Notable examples include the diffusion of ions and macromolecular solutes through channels of varying cross-section, such as pores in biological membranes, living tissues, zeolites, carbon nanotubes, and synthetic porous materials. In these systems, the observed diffusion can exhibit anomalous behavior characterized by a nonlinear increase in the mean squared displacement. In this article, we present a toy model of the diffusion of rod-shaped particles through a narrowing, conical pore with a trapezoidal longitudinal cross-section. Particles of different sizes undergo a random walk due to interactions with the environment (modeled as noise). We study how the diffusion properties change with particle size as a function of pore width. The numerical analysis of diffusion-driven transport through narrowing conical channels reveals its effective subdiffusive, i.e., anomalous, character.},\nDOI = {10.3390/e27030293}\n}\n\n

It has been intensively studied in recent years. Especially in biological cells, the movement of molecules through channel systems plays an essential role in controlling almost every physiological function of living organisms. The subject of our study is the kinetics of spherical particles passing through a conical pore restricted by absorbing and reflecting boundaries from a wider to a narrower end and vice versa. We study the properties of diffusion as a function of particle size with respect to pore width. Particles of different diameters are subjected to a random force. In addition to the mean squared displacement, which indicates the (effective) subdiffusive or superdiffusive character of the motion (depending on whether the absorbing boundary is located at the narrow or wide end of the channel), we measured the mean and median of the first passage times. Additional in silico experiments allowed us to thoroughly discuss the interplay of entropic forces and boundary conditions influencing the obtained results.},\n    issn = {1054-1500},\n    doi = {10.1063/5.0243989},\n    url = {https://doi.org/10.1063/5.0243989},\n    eprint = {https://pubs.aip.org/aip/cha/article-pdf/doi/10.1063/5.0243989/20400711/023143\\_1\\_5.0243989.pdf},\n}\n\n\n\n\n

As individual objects pass through a pore, they cause a transient change in the current that can be correlated with the object size, surface charge, and even chemical properties. The majority of experiments and modeling have been performed with spherical objects, while much less is known about the transport characteristics of aspherical particles, which would act as a model system, for example, for proteins and bacteria. The transport kinetics of aspherical objects is an especially important, yet understudied, problem in nanopore analytics. Here, using the Wiener process, we present a simplified model of the diffusion of rod-shaped particles through a cylindrical pore, and apply it to understand the translation and rotation of the particles as they pass through the pore. Specifically, we analyze the influence of the particles� geometrical characteristics on the effective diffusion type, the first passage time distribution, and the particles� orientation in the pore. Our model shows that thicker particles pass through the channel slower than thinner ones, while their lengths do not affect the passage time. We also demonstrate that both spherical and rod-shaped particles undergo normal diffusion, and the first passage time distribution follows an exponential asymptotics. The model provides guidance on how the shape of the particle can be modified to achieve an optimal passage time.},\nDOI = {10.3390/molecules29163795}\n}\n\n

The model with continuous positional and orientational degrees of freedom was considered. During sedimentation, the particle undergoes random translational and rotational Brownian motions and downward movements controlled by gravitation. Interrelation between gravitational and random motions was determined by the P�clet number varied in the interval $Pe=0.05-0.2$ (i.e. random walks were dominant). The value of particle aspect ratio (the length-to-width ratio) was varied in the interval $\\varepsilon=1.1-10$. In the studied systems, the initial hindered sedimentation process was followed by a consolidation process at the bottom sediment. Studies revealed the complicated sedimentation-driven self-assembly, orientational ordering, and formation of stacks (tactoids) in sediment films. Permeability of sediment films was tested using the random walker method and was characterized by diffusion coefficient through the sediment film $D$. The evolution of the deposit height, order parameter, and diffusion coefficient $D$ at different values of $\\varepsilon$ and $Pe$ are discussed.}\n}\n\n

The competitive random sequential adsorption (RSA) with simultaneous deposition of particles was considered. The aspect ratio was changed within the range $\\varepsilon=1-10$. In the competitive model, the particle was selected with probability $p_d$ (disks) and $p_\\varepsilon=1-p_d$ (discorectangles), and then they were placed sequentially on a solid surface without overlapping with previously placed particles. Behavior of the total coverage in jamming state $\\phi_T$  at different values of $p_d$ and $\\varepsilon$ was analyzed. For core–shell structure of the particles the percolation connectivity of films was also discussed.}\n}\n\n

The Axelrod model is based on two sociological phenomena: homophily (a tendency for individuals to form bonds with people similar to themselves) and social influence (the way how individuals change their behavior due to social pressure). However, the Axelrod model does not take into account the fact that cultural attributes may have different significance for a given individual. This is a limitation in the context of how the model reflects mechanisms driving the evolution of real societies. The study aims to modify the Axelrod model by giving individual features different weights that have a decisive impact on the possibility of aligning cultural traits between (interacting) individuals. The comparison of the results obtained for the classic Axelrod model and its modified version shows that introduced weights have a significant impact on the course of the system development, in particular, increasing the final fragmentation of the system and increasing the time needed to reach the final state.}\n}\n\n

Incorporation of the resetting to the random walks can result in a decrease in the mean first passage time due to the ability to limit unfavorably meandering, sub-optimal trajectories. In this paper, we examine how stochastic resetting influences escape dynamics from the   ( − ∞ , 1 ) interval in the presence of the single-well power-law    | x   | κ potentials with   κ \\\\&gt; 0. Examination of the mean first passage time is complemented by the analysis of the coefficient of variation, which provides a robust and reliable indicator assessing the efficiency of stochastic resetting. The restrictive nature of resetting is compared to placing a reflective boundary in the system at hand. In particular, for each potential, the position of the reflecting barrier giving the same mean first passage time as the optimal resetting rate is determined. Finally, in addition to reflecting, we compare the effectiveness of other resetting strategies with respect to optimization of the mean first passage time.}",\n    issn = {1054-1500},\n    doi = {10.1063/5.0159475},\n    url = {https://doi.org/10.1063/5.0159475},\n    eprint = {https://pubs.aip.org/aip/cha/article-pdf/doi/10.1063/5.0159475/18169355/103124\\_1\\_5.0159475.pdf},\n}\n\n

In out-of-equilibrium setups, e.g., for motions under action of Lévy noises, the existence of the stationary state is not only determined by the potential but also by the noise. Potential wells need to be steeper than parabolic in order to assure the existence of stationary states. The existence of stationary states, in sub-harmonic potential wells, can be restored by stochastic resetting, which is the protocol of starting over at random times. Herein, we demonstrate that the combined action of Lévy noise and Poissonian stochastic resetting can result in the phase transition between non-equilibrium stationary states of various multimodality in the overdamped system in super-harmonic potentials. Fine-tuned resetting rates can increase the modality of stationary states, while for high resetting rates, the multimodality is destroyed as the stochastic resetting limits the spread of particles.}",\n    issn = {1054-1500},\n    doi = {10.1063/5.0143821},\n    url = {https://doi.org/10.1063/5.0143821},\n    note = {063105},\n    eprint = {https://pubs.aip.org/aip/cha/article-pdf/doi/10.1063/5.0143821/17960782/063105\\_1\\_5.0143821.pdf},\n}\n\n

The efficiency of the escape process or time scales matching is responsible for occurrence of the stochastic resonance and (stochastic) resonant activation. Here, we are extending the discussion on how the structure of the potential can be used to optimize the mean first passage time. It is demonstrated that corrugation of the potential can be beneficial under action of the weak Gaussian white noise. Furthermore, we show that the noise tuning can be more effective than shaping the potential. Therefore, action of the tuned additive α-stable noise can accelerate the escape kinetics more than corrugation of the potential. Finally, we demonstrate that mean first passage time from a potential well can be a non-monotonous function of the stability index α.}\n}\n\n

One of the most important factors that is widely believed to be crucial for the formation of new phases is the pear-like shape of mesogenic molecules. Such molecules were treated using second-virial density functional theory in [De Gregorio{,} P et al.{,} Soft Matter{,} 2016{,} 12(23){,} 5188–5198]{,} where the authors showed that the K11 splay elastic constant can become negative due to solely entropic reasons leading to long-range splay and polar correlations. To verify whether the predictions are correct{,} we performed Monte Carlo simulations of the same hard–core molecules used in the DFT study. As our results suggest{,} no polar or modulated liquid crystalline phases emerge; polar and splay correlations are either at most short-range or completely absent. On the other hand{,} a polar ferroelectric splay crystal was observed."}\n\n

The purpose of this study is to understand the relationship between membrane structures, external forces, and the characteristic features of diffusive transport. We investigate Cauchy flight diffusion with drift in heterogeneous membrane-like structures. The study focuses on numerical simulation of particle movement across different membrane structures with differently spaced obstacles. Four studied structures are similar to real polymeric membranes filled with inorganic powder, while the next three structures are designed to show which distribution of obstacles can cause changes in transport. The movement of particles driven by Cauchy flights is compared to a Gaussian random walk both with and without additional drift action. We show that effective diffusion in membranes with an external drift depends on the type of the internal mechanism that causes the movement of particles as well as on the properties of the environment. In general, when movement steps are provided by the long-tailed Cauchy distribution and the drift is sufficiently strong, superdiffusion is observed. On the other hand, strong drift can effectively stop Gaussian diffusion.},\nDOI = {10.3390/membranes13040417}\n}\n\n

The system is known to spontaneously break mirror symmetry, as it forms a macroscopically chiral, twist-bend nematic phase [Phys. Rev. Lett. 115, 147801 (2015)]. We examined a full phase diagram by altering the molecules’ curvature along with packing fractions and observed several phases characterized by the orientational and/or translational ordering of molecules. Apart from conventional nematic, smectic A, and the aforementioned twist-bend nematic phase, we identified splay-bend smectic phase. For large densities and strongly curved molecules, another smectic phase emerged, where the polarization vector rotates within a single smectic layer.}\n}\n\n

This design offers the possibility to combine the polymer&rsquo;s easy processability and superior separation performance. For a better understanding of the mechanisms of mixture separation, we analyze the diffusion motion of a particle in the hybrid membrane environment. We model structures of two-dimensional heterogenic membranes, which resemble real membrane structures, and then we simulate a random walk on them. We investigate how the additional action of drift changes the motion properties of the diffusing particles through the polymeric membrane filled with inorganic powder. We test the effect of two parameters: the distribution of obstacles (filling) in the membrane and the value of drift on the nature of diffusion. It appears that the synergy between drift, the diffusion, and the membrane structure affect the occurrence of the superdiffusive and subdiffusive character of particle motion as measured by the time-averaged mean square displacement. An important point is the observation that the strong drift supports subdiffusive motion as it increases the chances of particle trapping. Moreover, there exists the optimal value of drift, for which the transport through a membrane speeds up and does not cause trapping.},\nDOI = {10.3390/membranes12080788}\n}\n\n

These factors may lead to the formation of single- or double-strand breaks. Recently, an atomic force microscopy emerged as an attractive tool for determination of the length of DNA fragments deposited at surfaces, allowing quantification of double-strand breaks (DSBs). In spite of this, the length of objects provided via AFM is strictly related to the image spatial resolution, which in consequence leads to underestimation of DSBs quantity. To correct this deficiency, we provide here a novel methodology based on statistics of DNA fragments length. This approach allows for highly accurate determination of the DSBs number. Moreover, we provide the software that enables to automatically calculate the number of DSBs according to the described methodology. Finally, the method is applied for characterization of the DNA plasmid fragmentation by bleomycin - an anticancer chemotherapeutic drug.}\n}\n\n

In the first part of this paper, we demonstrate how the RSA model can be applied to interpret the experimental data and extract information about the density of the adsorption monolayer, the kinetics of its growth, and microstructural properties such as pair-correlation function and monolayer roughness. We briefly summarized the most important generalizations of the RSA model for monolayers and reviewed its extensions considering, e.g., various particle shapes, the introduction of electrostatic interaction, or adsorption on non-uniform substrates. We thoroughly scrutinized the extended RSA model developed for bilayer and multilayer formation. We collected the mean saturated packing fractions of various two- and three-dimensional objects and provided the most accurate result for two-dimensional disk packing. In the second part of this paper, we summarize various numerical algorithms and techniques that allow one to effectively implement RSA algorithms. We describe efficient methods for detecting intersections of various shapes and techniques enabling generation of strictly saturated RSA packings built of a wide range of different shapes. We hinted at how an inherently sequential RSA scheme can be parallelized. Finally, we critically discuss the limitations of the model and possible directions for future studies.}\n}\n\n

It was determined how surface structure influences random packing properties such as the packing fraction, the kinetics of packing growth and the two-particle density correlation function. Until the substrate varies within the range one order of magnitude smaller than the particle’s diameter, the properties of the packings obtained do not differ significantly from those on a flat surface. On the other hand, for the higher amplitude of unevenness, the packing fraction, low-density growth kinetics and the density autocorrelation function change significantly, while asymptotic growth kinetics seems to be barely sensitive to surface waviness. Besides fundamental significance, the study suggests that the experimental measurement of the aforementioned basic properties of adsorption monolayers can reveal the surface’s porous structure without investigating the surface itself.}\n}\n\n

The motion of such a particle is described by the full Langevin equation and the particle is characterized by the position and velocity. We compare three resetting protocols, which restarts velocity or position (partial resetting) and the whole motion (position and velocity—full resetting). Using the mean first passage time we assess efficiency of restarting protocols in facilitating or suppressing the escape kinetics. There are fundamental differences between partial resetting scenarios which restart velocity or position, as in the limit of very frequent resets only the position resetting (regardless of initial velocity) can trap the particle in the finite domain of motion. The velocity resetting or the simultaneous position and velocity restarting provide a possibility of facilitating the undamped escape kinetics.}\n}\n\n

Here, we demonstrate a minimal, deterministic force-free setup allowing for the occurrence of resonant, noise-induced effects. We show that in the archetypal problem of escape from finite intervals driven by α-stale noise with a periodically modulated stability index, depending on the initial direction of the modulation, resonant-activation-like or noise-enhanced-stability-like phenomena can be observed. Consequently, in comparison to traditional Lévy flights, Lévy flights with a time-dependent jump length exponent are capable of facilitating or slowing down the escape from finite intervals in an analogous way, such as the modulation of the potential in the resonant activation setup.}\n}\n\n

Basic physicochemical characteristics of fibrinogen and the particles were acquired using dynamic light scattering and the electrophoretic mobility methods, whereas the zeta potential of the substrates was determined using streaming potential measurements. Subsequently, an efficient method for the preparation of the particles with coronas, characterized by a controlled fibrinogen coverage, was developed. This enabled us to carry out measurements, which confirmed that the deposition kinetics of the particles at mica vanished at pH above 5. In contrast, the particle deposition of PLL modified mica was at maximum for pH above 5. It was shown that the deposition kinetics could be adequately analyzed in terms of the mean-field approach, analogously to the ordinary colloid particle behavior. This contrasts the fibrinogen molecule behavior, which efficiently adsorbs at negatively charged substrates for the entire range pHs up to 9.7. These results have practical significance for conducting label-free immunoassays governed by the specific antigen/antibody interactions.},\nDOI = {10.3390/molecules26206299}\n}\n\n\n\n\n\n

Applying the Monte-Carlo type, random sequential modeling, the kinetics of particle deposition, their maximum coverage and the structure of the layers were determined. It is shown that the maximum coverage of the nanoparticles linearly decreases with the heterogeneity degree quantified in terms of the larger particle coverage. It is also confirmed that the nanoparticle layers exhibit a pronounced short-range ordering analogous to a two-dimensional liquid phase. The theoretical results derived from the modeling are used to interpret nanoparticle deposition kinetics acquired by the atomic force microscopy and the quartz microbalance (QCM) measurements. This allowed to determine the hydration function, which enables a proper interpretation of the QCM signal for the heterogeneous systems, extending the applicability range of this technique. Given that the problem of nanoparticle deposition on geometrically heterogeneous surfaces, relevant for predicting protein, virus and other bioparticle behavior, was not treated in the literature before, the results obtained in this work significantly advance the field of colloid science.}\n}\n\n

Sleep loss causes perturbations of circadian rhythmicity and degradation of waking alertness as reflected in attention, cognitive efficiency and memory. Understanding whether and how the human brain recovers from chronic sleep loss is important not only from a scientific but also from a public health perspective. In this work we report on behavioral, motor, and neurophysiological correlates of sleep loss in healthy adults in an unprecedented study conducted in natural conditions and comprising 21 consecutive days divided into periods of 4 days of regular life (a baseline), 10 days of chronic partial sleep restriction (30\\% reduction relative to individual sleep need) and 7 days of recovery. Throughout the whole experiment we continuously measured the spontaneous locomotor activity by means of actigraphy with 1-minute resolution. On a daily basis the subjects were undergoing EEG measurements (64-electrodes with 500 Hz sampling frequency): resting state with eyes open and closed (8 minutes long each) followed by Stroop task lasting 22 minutes. Altogether we analyzed actigraphy (distributions of rest and activity durations), behavioral measures (reaction times and accuracy from Stroop task) and EEG (amplitudes, latencies and scalp maps of event-related potentials from Stroop task and power spectra from resting states). We observed unanimous deterioration in all the measures during sleep restriction. Further results indicate that a week of recovery subsequent to prolonged periods of sleep restriction is insufficient to recover fully. Only one measure (mean reaction time in Stroop task) reverted to baseline values, while the others did not.},\n    number = {9},\n\n}\n\n

For that purpose, we have performed a version of steered molecular dynamics (SMD) calculations. The sample trajectories have been analyzed to derive distribution of work done on the system. In order to induce stretching of the linker, we have applied a constant pulling force to the molecule and allowed for a subsequent relaxation of its structure. The use of fluctuation relations (FR) relevant to non-equilibrium systems subject to thermal fluctuations allows us to assess the difference in free energy between stretched and relaxed conformations. To further understand effects of potential mutations on elastic properties of the linker, we have performed similar in silico studies on a structure formed of a polyalanine sequence (Ala-only) and on three other structures, created by substituting selected types of amino acid residues in the linker's sequence with alanine (Ala) ones. The results of SMD simulations indicate a crucial role played by the Asparagine (Asn) and Lysine (Lys) residues in controlling stretching and relaxation properties of the linker domain of the motor.},\ndoi={10.1038/s41598-020-61399-z}\n}\n\n\n\n

Under certain constraints, mathematical theory can advance predictions of the expected neural dynamics based solely on the statistical properties of the synaptic interaction matrix. This work explores the application of free random variables to the study of large synaptic interaction matrices. Besides recovering in a straightforward way known results on eigenspectra in types of models of neural networks proposed by Rajan and Abbott (2006), we extend them to heavy-tailed distributions of interactions. More important, we analytically derive the behavior of eigenvector overlaps, which determine the stability of the spectra. We observe that on imposing the neuronal excitation/inhibition balance, despite the eigenvalues remaining unchanged, their stability dramatically decreases due to the strong nonorthogonality of associated eigenvectors. This leads us to the conclusion that understanding the temporal evolution of asymmetric neural networks requires considering the entangled dynamics of both eigenvectors and eigenvalues, which might bear consequences for learning and memory processes in these models. Considering the success of free random variables theory in a wide variety of disciplines, we hope that the results presented here foster the additional application of these ideas in the area of brain sciences. }\n}\n\n

By solving the space-fractional diffusion equation, we analyse the fractional-order moments of the first-passage time probability density function for different values of the index of stability and the skewness parameter. A comparison with results using the Langevin approach to Lévy flights is presented. For the semi-infinite domain, in certain special cases analytic results are derived explicitly, and in bounded intervals a general analytical expression for the mean first-passage time of Lévy flights with arbitrary skewness is presented. These results are complemented with extensive numerical analyses.}\n}\n\n\n

When implemented for systems close to equilibrium, the approach correctly explains the emergence of the Boltzmann distribution for the ensemble of trajectories generated by the Langevin equation and relates the intensity of the noise strength to the mobility. This scenario can be further generalized to include effects of non-Gaussian, burstlike forcing modeled by Lévy noise. In this case, however, the pulsatile additive noise cannot be treated as the internal (thermal) since the relation between the strength of the friction and variance of the noise is violated. Heavy tails of Lévy noise distributions not only facilitate escape kinetics, but also, more importantly, change the escape protocol by altering the final stationary state to a non-Boltzmann, nonequilibrium form. As a result, contrary to the kinetics induced by a Gaussian white noise, escape rates in environments with Lévy noise are determined not by the barrier height, but instead by the barrier width. We further discuss consequences of simultaneous action of thermal and Lévy noises on statistics of passage times and population of reactants in double-well potentials.}\n}\n\n

This study presents a solution that can be used for any molecule occupying the surface that can be modelled by any number of different disks. Additionally, the presented algorithm stops when there is no possibility to add another shape to the monolayer. This allows to study properties of fully saturated, two-dimensional random packings built of complex shapes.

For suitable choices, this “dielectric Skyrme model” has static solutions saturating the pertinent topological bound in the sector of baryon number (or topological charge) B=±1 but not for higher |B|. This implies that higher charge field configurations are unbound, and loosely bound higher skyrmions can be achieved by small deformations of this dielectric Skyrme model. We provide a simple and explicit example for this possibility. Further, we show that the |B|=1 BPS sector continues to exist for certain generalizations of the model like, for instance, after its coupling to a specific version of the BPS Skyrme model, i.e., the addition of the sextic term and a particular potential."\n}\n\n

The increase of the conductivity of conjugated material is one of the effects that is well documented in the literature. However, to-this-day there is no consistent explanation for this phenomenon. Herein, a lamellar system based on the regioregular poly(3-hexylthiophene) (R-P3HT), and the recently developed poly(4-vinylpyridine) (P4VP) cross-linked with d-block metal complexes is studied. Bilayer samples, mimicking organic Field Effect Transistors, are fabricated in a three-step procedure: (i) R-P3HT thin film casting, (ii) subsequent P4VP film casting on top of the R-P3HT, and (iii) cross-linking of the P4VP surface. The Cobalt and Zinc complexes exist only on the surface of the bilayer and do not penetrate the semiconductor. The conductivity of the system increases with each preparation step, to reach a value four orders higher as compared to the as-cast R-P3HT. Additional experiments show that the described effect is a consequence of the contact of R-P3HT and P4VP. Observed increase in the system's conductivity is attributed to the electric field induced in the semiconductor area by the pyridine dipole moments directed by surface-oriented metal complex. These findings open up new possibilities in tuning the performance of organic electronic devices."\n}\n\n

Each of them consists of two parts: subdiffusion based on the continuous-time random walk scheme and independent resetting events generated uniformly in time according to the Poisson point process. In the first model the whole process is reset to the initial state, whereas in the second model only the position is subject to resets. The distinction between these two models arises from the non-Markovian character of the subdiffusive process. We derive exact expressions for the two lowest moments of the full propagator, stationary distributions, and first hitting time statistics. We also show, with an example of a constant drift, how these models can be generalized to include external forces.

In this work, we apply the over-damped SCN-driven Langevin equations as an effective, one-component model of the dynamics in dense binary mixtures. We derive the thermodynamically consistent fluctuation-dissipation relation for SCN to show that it predicts the molecular arrest resembling the glass transition, i.e. the critical slow-down of dynamics in the disordered phases. We show that the mechanism of singular dissipation is embedded in the dissipation matrix, accompanying SCN. We are also able to identify the characteristic length of collective dissipation, which diverges at critical packing. This novel physical quantity conveniently describes the difference between the ergodic and non-ergodic dynamics. The model is fully analytically solvable, one-dimensional and admits arbitrary interactions between the particles. It qualitatively reproduces several different modes of arrested disorder encountered in binary mixtures, including e.g. the re-entrant arrest. The model can be effectively compared to the mode coupling theory.},\ndoi={10.1038/s41598-019-54321-9},\nurl={https://doi.org/10.1038/s41598-019-54321-9}\n}\n\n

As a result, the variance of Lévy flights diverges and the trajectory is characterised by occasional extremely long jumps. Such long jumps significantly decrease the probability to revisit previous points of visitation, rendering Lévy flights efficient search processes in one and two dimensions. To further quantify their precise property as random search strategies we here study the first-passage time properties of Lévy flights in one-dimensional semi-infinite and bounded domains for symmetric and asymmetric jump length distributions. To obtain the full probability density function of first-passage times for these cases we employ two complementary methods. One approach is based on the space-fractional diffusion equation for the probability density function, from which the survival probability is obtained for different values of the stable index  and the skewness (asymmetry) parameter . The other approach is based on the stochastic Langevin equation with -stable driving noise. Both methods have their advantages and disadvantages for explicit calculations and numerical evaluation, and the complementary approach involving both methods will be profitable for concrete applications. We also make use of the Skorokhod theorem for processes with independent increments and demonstrate that the numerical results are in good agreement with the analytical expressions for the probability density function of the first-passage times.}\n}\n\n

Nevertheless, in the long-time limit (t→), the average energies grow as power law with exponents dependent on the steepness of the potential n.

In the simplest version Lévy walks move with a finite speed. Here, we present an extension of the Lévy walk scenario for the case when external force fields influence the motion. The resulting motion is a combination of the response to the deterministic force acting on the particle, changing its velocity according to the principle of total energy conservation, and random velocity reversals governed by the distribution of waiting times. For the fact that the motion stays conservative, that is, on a constant energy surface, our scenario is fundamentally different from thermal motion in the same external potentials. In particular, we present results for the velocity and position distributions for single well potentials of different steepness. The observed dynamics with its continuous velocity changes enriches the theory of Lévy walk processes and will be of use in a variety of systems, for which the particles are externally confined. © 2018 IOP Publishing Ltd.},\nauthor_keywords={conservative random walks;  Lévy flight;  Lévy walk},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Measurements were performed at pH 3.5, 4, and 7.4 for various ionic strengths. The experimental data were interpreted in terms of a hybrid random sequential adsorption model. This allowed the mass transfer rate coefficient for the OWLS cell and maximum coverages to be determined at various pHs. The appearance of different, pH-dependent mechanisms of fibrinogen adsorption on silica substrates was confirmed. At pH 3.5 the molecules mostly adsorb in the side-on orientation that produces a low maximum coverage of ca. 1 mg m-2. At this pH, the kinetics derived from the OWLS measurements agree with those theoretically predicted using the convective-diffusion theory. In consequence, a comparison of the OWLS and QCM results allows the water factor and the dynamic hydration of fibrinogen molecules to be determined. At pH 7.4, the OWLS method gives inaccurate kinetic data for the low coverage range. However, the maximum coverage that was equal to ca. 4 mg m-2 agrees with the QCM results and with previous literature results. It is postulated that the limited accuracy of the OWLS method for lower coverage stems from a heterogeneous structure of fibrinogen monolayers, which consist of side-on and end-on adsorbed molecules. One can expect that the results acquired in this work allow development of a robust procedure for preparing fibrinogen monolayers of well-controlled coverage and molecule orientation, which can be exploited for efficient immunosensing purposes.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Using size-excursion chromatography (SEC), dynamic light scattering (DLS), native-PAGE and atomic force microscopy (AFM) we studied the nature of enzyme aggregation. Partial protein de-aggregation was facilitated by the presence of non-ionic detergent such as Tween 20 or by a high degree of protein dilution but not by addition of a reducing agent or an increase of ionic strength. De-aggregating influence of Tween 20 had no impact on either enzyme's specific activity or FAD reconstitution to recombinant AcmB. The joint experimental (DLS, isoelectric focusing) and theoretical investigations demonstrated gradual shift of enzyme's isoelectric point upon aggregation from 8.6 for a monomeric form to even 5.0. The AFM imaging on mica or highly oriented pyrolytic graphite (HOPG) surface enabled observation of individual protein monomers deposited from a highly diluted solution (0.2 μg/ml). Such approach revealed that native AcmB can indeed be monomeric. AFM imaging supported by theoretical random sequential adsorption (RSA) kinetics allowed estimation of distribution enzyme forms in the bulk solution: 5\\%, monomer, 11.4\\% dimer and 12\\% trimer. Finally, based on results of AFM as well as analysis of the surface of AcmB homology models we have observed that aggregation is most probably initiated by hydrophobic forces and then assisted by electrostatic attraction between negatively charged aggregates and positively charged monomers. © 2019 Elsevier B.V.},\nauthor_keywords={Adsorption kinetics;  Atomic force microscopy of proteins;  Isoelectric point;  Protein aggregation;  Quaternary structure;  Size excursion chromatography},\nkeywords={dimer;  flavine adenine nucleotide;  monomer;  oligomer;  polysorbate 20;  steroid reductase, Article;  atomic force microscopy;  dehydrogenation;  denitrifying bacterium;  ionic strength;  isoelectric focusing;  molecular model;  nonhuman;  photon correlation spectroscopy;  polyacrylamide gel electrophoresis;  priority journal;  protein aggregation;  protein quaternary structure;  size exclusion chromatography;  Sterolibacterium denitrificans},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Besides nematic, chiral twist-bend nematic and cholesteric phases of vanishing global polarization, we find their polar analogues.

Here we investigate theoretically how an external uniform field can affect structural properties and the stability of NTB. Assuming that the driving force responsible for the formation of this phase is packing entropy, we show, within Landau-de Gennes theory, that NTB can undergo a rich sequence of structural changes with the field. For the systems with positive anisotropy of permittivity, we first observe a decrease of the tilt angle of NTB until it transforms through a field-induced phase transition to the ordinary prolate uniaxial nematic phase (N). Then, at very high fields, this nematic phase develops polarization perpendicular to the field (Np+). For systems with negative anisotropy of permittivity, the results reveal new modulated structures. Even an infinitesimally small field transforms NTB to its elliptical counterpart (NTBe), where the circular base of the cone of the main director becomes elliptic. With stronger fields, the ellipse degenerates to a line, giving rise to a nonchiral periodic structure, the nematic splay- bend (NSB), where the two nematic directors are restricted to a plane. The three structures-NTB, NTBe, and NSB-with a modulated polar order are globally nonpolar. But further increase of the field induces phase transitions into globally polar structures with nonvanishing polarization along the field's direction. We found two such structures, one of which is a polar and chiral modification of NSB, where splay and bend deformations are accompanied by weak twist deformations (N∗ SBp). Further increase of the field unwinds this structure into a polar nematic (Np) of polarization parallel to the field. © 2018 National Academy of Sciences.

In accordance to one’s expectations, we confirm that energy is pumped into the system. We demonstrate that, as a function of time, initially total energy displays abrupt oscillatory changes, but then transits to the linear dependence in the long-time limit.

The measurements were carried out at pHs 3.5 and 7.4 and for NaCl/PBS concentration of 10-2 and 0.15 M. Initially, the dependence of the electrophoretic mobility and zeta potential of microparticles on the bulk concentration of lysozyme was determined. These results were interpreted in terms of the general electrokinetic model. This allowed the authors to devise a formula for precise determination of lysozyme coverage at microparticles under in situ conditions. The maximum coverage of irreversibly adsorbed lysozyme was also determined with the use of the electrokinetic concentration depletion methods and the ELISA assay. At pH 7.4 (PBS buffer) and ionic strength of 0.15 M, the maximum coverage was equal to 0.95 mg m-2 that agrees with theoretical modeling performed according to the random sequential adsorption approach. The stability of acid base properties of lysozyme monolayers was also determined via the electrophoretic mobility measurements carried out for different ionic strength and pH range of 3-12.

For a symmetric but otherwise arbitrary distribution fG(x) we find the optimal potential that minimizes the MFPT. The minimal MFPT is given by a nonstandard measure of the dispersion, which can be related to the cumulative Rényi entropy. We compare optimal times in this model with optimal times obtained for the model of diffusion with stochastic resetting, in which the diffusive motion is interrupted by intermittent jumps (resets) to the initial position.

Recently, we have proposed a novel type of thermodynamically consistent Langevin dynamics driven by spatially correlated noise (SCN) that can contribute to the understanding of this problem. This model draws a link between the theory of effective interactions in binary colloidal mixtures and the properties of SCN. In the current article, we review this model from the perspective of collective diffusion and generalize it to the case of multiple (N > 2) particles. Since our theory of SCN-driven Langevin dynamics has certain issues that could not be resolved within this framework, in this article we also provide another approach to the problem of collectivity. We discuss the multi-particle Mori-Zwanzig model, which is fully microscopically consistent. Indeed, we show that this model supplies a lot of information, complementary to the SCN-based approach, e.g. it predicts the deterministic dynamics of the relative distance between the particles, it provides an approximation for non-equilibrium effective interactions and predicts the collective sub-diffusion of tracers in the group. These results provide the short-range, inertial limit of the earlier model and agree with its predictions under some general conditions. In this article we also review the origin of SCN and its consequences for a variety of physical systems, with emphasis on the colloids. © 2017 IOP Publishing Ltd.},\nauthor_keywords={collective diffusion;  colloids;  effective interactions;  generalized Langevin equation;  spatially correlated noise},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Here, we show how presence of two favored (leading) nodes affects properties of the network connecting individuals. In particular, we study how nodes characteristics depend on relative asymmetry between two leading nodes. It is shown that without strong and rigorous avoidance mechanism, individuals can support both dominating nodes. Slow redistribution of resources enhances this effect. Moreover, slow redistribution of resources results in development of social networks with a very limited number of layers. © 2017 World Scientific Publishing Company.},\nauthor_keywords={complex networks;  hierarchy development;  hierarchy maintenance;  Social dynamics},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Thorough electrophoretic mobility measurements were carried out that enabled to monitor in situ the progress of protein adsorption. The maximum coverage of irreversibly adsorbed HSA on microparticles was determined by different concentration depletion methods, one of them involving AFM imaging of residual molecules. An anomalous adsorption of HSA on the positive microparticles was observed at pH 3.5 where the maximum coverage attained 1.0 mg m−2 for NaCl concentrations of 0.05 M despite that the molecules were on average positively charged. For comparison, the maximum coverage of HSA on negatively charged microparticles was equal to 1.3 mg m−2 at this pH and NaCl concentration. At pH 7.4 the maximum coverage on positive microparticles was equal to 2.1 mg m−2 for 0.05 M NaCl concentration. On the other hand, for negative microparticles, negligible adsorption of HSA was observed at pH 7.4 and 9.7. These experimental data were adequately interpreted in terms of the random sequential adsorption approach exploiting the bead model of the HSA molecule. Different orientations of adsorbed molecules, inert alia, the edge-on orientation prevailing for positively charged microparticles at pH 7.4, were confirmed. This was explained in terms of a heterogeneous charge distribution over the HSA molecule prevailing for a wide range of pHs. © 2017 Elsevier B.V.},\nauthor_keywords={Adsorption of HSA on microparticles;  HSA adsorption on microparticles;  HSA monolayers;  Maximum coverage of HSA on microparticles;  Monolayers of HSA on microparticles;  Zeta potential of HSA covered microparticles},\nkeywords={Body fluids;  Electrophoretic mobility;  Molecules;  Monolayers;  Sodium chloride, Adsorbed molecules;  Formation mechanism;  Human serum albumin adsorption (HSA);  Human serum albumins;  Micro-particles;  Polystyrene microparticles;  Positively charged;  Random sequential adsorption, Adsorption, human serum albumin;  polystyrene;  sodium chloride;  human serum albumin;  polymer, adsorption;  Article;  chemical structure;  controlled study;  electrophoretic mobility;  pH;  physical chemistry;  priority journal;  theoretical model;  chemistry;  human;  membrane microparticle, Adsorption;  Cell-Derived Microparticles;  Humans;  Hydrogen-Ion Concentration;  Polymers;  Serum Albumin, Human;  Sodium Chloride},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The mesh is built of straight horizontal and vertical one-dimensional lines of a given distance between them. The packing fraction and structure as well as the kinetics of packing growth dependence on mesh size are analyzed to provide information, whether surface inhomogeneity will affect the properties of random packings. It has been shown that the number of disks in a packing slightly decreases with growing distance between mesh lines while the kinetics may change significantly even for very dense meshes. As packings obtained in random sequential adsorption resemble monolayers produced by irreversible adsorption processes, results of this study show that by measuring properties of a random packing it may be possible to determine fine structure of an underlying surface. © 2017 Author(s).},\nkeywords={Adsorption;  Atomic physics;  Growth kinetics;  Mesh generation, Fine structures;  Irreversible adsorption;  Packing fractions;  Random packing;  Random sequential adsorption;  Surface fines;  Surface inhomogeneity;  Underlying surface, Packing},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In the experimental part, the morphology of membranes is described by the following characteristics: the amount of polymer matrix, the fractal dimension of polymer matrix, the average size of polymer matrix domains, the average number of obstacles in the proximity of each polymer matrix pixel. The simulation work concentrates on the motion of a particle in the membrane environment. The focus is set on the relationship between membranes morphology characterized by polymer matrix density, its fractal dimension, the average size of domains, and the average number of near obstacles and the characteristics of diffusive transport in them. The comparison of diffusion driven by Gaussian random walk and Lévy flights shows that the effective diffusion exponent at long time limits is subdiffusive and it does not depend on the details of the underlying random process causing diffusion. The analysis of the parameters describing the membrane structure shows that the most important factor for the diffusion character is the average size of a domain penetrated by diffusing particles. The presented results may be used in the design and preparation of membrane structures with specific diffusion properties. © 2017 American Physical Society.},\nkeywords={Composite membranes;  Diffusion;  Fractal dimension;  Fractals;  Matrix algebra;  Membrane structures;  Particle size analysis;  Polymer matrix;  Random processes, Diffusing particles;  Diffusion character;  Diffusion properties;  Diffusive transport;  Effective diffusion;  Gaussian random walk;  Membranes morphology;  Two dimensional diffusion, Membranes},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Additionally, quantum–chemical model based on the density functional theory was also applied. It was found that mixture studied did not exhibit antiferroelectric phase at any rate of heating or cooling in contradiction to its ingredients. On the other hand it has a wide temperature range of ferroelectric smectic C* phase, which is invariant with respect to different heating and cooling rates within the range of thermal hysteresis. Furthermore, temperature dependence of switching time and spontaneous polarization were measured.}\n}\n\n

Besides nematic and cholesteric phases, we find four bulk ODMNS for nonchiral materials, two of which, to the best of our knowledge, have not been reported so far. These two structures are longitudinal (NLP) and transverse (NTP) periodic waves where the polarization field being periodic in one dimension stays parallel and perpendicular, respectively, to the wave vector. The other two phases are the twist-bend nematic phase (NTB) and the splay-bend nematic phase (NSB), but their fine structure appears more complex than that considered so far. The presence of molecular chirality converts nonchiral NTP and NSB into new NTB phases.

However, when the overdamped particle is subjected to white Lévy noise, time-reversal symmetry is broken and microscopic reversibility is violated, even when the noise is symmetric. We, furthermore, derive how for an overdamped particle inside a parabolic potential microscopic reversibility is violated in the presence of Lévy white noise. Similar to Brownian vortexes, Lévy flights can be associated with the presence of Lévy vortexes in phase space. © CopyrightEPLA, 2016.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Previous studies on humans regularly deprived of sleep or suffering from sleep disorders predicted a change in the invariant scale parameters with respect to those for healthy subjects. In this study we investigate the signal patterns from actigraphy recordings by means of characteristic measures of fractional point processes. We analyse spontaneous locomotor activity of healthy individuals recorded during a week of regular sleep and a week of chronic partial sleep deprivation. Behavioural symptoms of lack of sleep can be evaluated by analysing statistics of duration times during active and resting states, and alteration of behavioural organisation can be assessed by analysis of power laws detected in the event count distribution, distribution of waiting times between consecutive movements and detrended fluctuation analysis of recorded time series. We claim that among different measures characterising complexity of the actigraphy recordings and their variations implied by chronic sleep distress, the exponents characterising slopes of survival functions in resting states are the most effective biomarkers distinguishing between healthy and sleep-deprived groups. © 2016 IOP Publishing Ltd and SISSA Medialab srl.},\nauthor_keywords={fluctuations (theory);  self-organised criticality (theory);  signal transduction (theory);  stochastic processes (theory)},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In particular, very little is known about the relation between friction and SCN. In this article, starting from the microscopic, deterministic model, we derive the analytical formula for the spatial correlation function in the particle-bath interactions. This expression shows that SCN is the inherent component of binary mixtures, originating from the effective (entropic) interactions. Further, employing this spatial correlation function, we postulate the thermodynamically consistent Langevin equation driven by the Gaussian SCN and calculate the adequate fluctuation-dissipation relation. The thermodynamical consistency is achieved by introducing the spatially variant friction coefficient, which can be also derived analytically. This coefficient exhibits a number of intriguing properties, e.g., the singular behavior for certain types of interactions. Eventually, we apply this new theory to the system of two charged particles in the presence of counter-ions. Such particles interact via the screened-charge Yukawa potential and the inclusion of SCN leads to the emergence of the anomalous frictionless regime. In this regime the particles can experience active propulsion leading to the transient attraction effect. This effect suggests a nonequilibrium mechanism facilitating the molecular binding of the like-charged particles. © 2016 American Physical Society.},\nkeywords={Bins;  Charged particles;  Differential equations;  Friction;  White noise, Analytical formulas;  Deterministic modeling;  Fluctuation-dissipation relation;  Friction coefficients;  Nonequilibrium mechanisms;  Spatial correlation functions;  Spatially correlated noise;  Temporal correlations, Binary mixtures},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In this work, monolayers of dHSA on polystyrene microparticles were prepared and thoroughly characterized. The changes in the electrophoretic mobility of microparticles upon the addition of controlled amounts of dHSA were measured using Laser Doppler Velocimetry (LDV) technique. These dependencies were quantitatively interpreted in terms of the 3D electrokinetic model. This allowed to determine the coverage of dHSA on microparticles under in situ conditions. Additionally, the maximum coverage of dHSA was precisely determined by the concentration depletion method. At physiological ionic strength, the maximum coverage of dHSA monolayer on microparticles was 1.05 mg m−2. This agrees with the theoretical value predicted from the random sequential adsorption approach by assuming a side-on orientation of molecules. A high stability of the monolayers under pH cycling was confirmed, which proved irreversibility of the protein adsorption on the microparticles. The obtained results can be exploited to prepare and characterize polymeric drug-capsule conjugated with albumin dimer. © 2016 Elsevier B.V.},\nauthor_keywords={Adsorption of dimeric HSA on microspheres;  HSA in dimeric form adsorption on microspheres;  Isoelectric point of dHSA monolayers on microspheres;  Monolayers of dimeric HSA on microspheres},\nkeywords={Adsorption;  Dimers;  Doppler effect;  Electrodynamics;  Electrophoretic mobility;  Ionic strength;  Laser Doppler velocimeters;  Microspheres;  Polymers, Electrokinetic characteristics;  Iso-electric points;  Laser Doppler Velocimetry;  Orientation of molecules;  Physiological ionic strength;  Polymeric microparticles;  Polystyrene microparticles;  Random sequential adsorption, Monolayers, dimer;  human serum albumin;  human serum albumin dimer;  polystyrene;  unclassified drug;  microsphere;  polymer;  serum albumin, adsorption;  Article;  chemical phenomena;  concentration (parameters);  controlled study;  electrokinetics;  electrophoretic mobility;  ionic strength;  laser Doppler flowmetry;  molecule;  pH;  priority journal;  quantitative analysis;  chemistry;  dimerization;  human;  kinetics, Adsorption;  Dimerization;  Humans;  Kinetics;  Microspheres;  Polymers;  Serum Albumin},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The structure of the pattern formed by magnetic particles in the membrane matrix was studied. Description of the system was based on the phenomenological and molecular (random walk on a fractal lattice) approaches. Two parameters were calculated: the fractal dimension of random walk dw, and the fractal dimension of membrane structure df. The knowledge of both parameters made it possible to use the generalized equation of diffusion on the fractal structure obtained by Metzler et al. The research was carried out to determine the influence of magnetic powder granulation on the transport properties. The results showed that the random walk within the membranes of the smallest magnetic powder granulation was of the most subdiffusive character.

The experimental were interpreted in terms of theoretical calculations performed according to the random sequential adsorption model (RSA). In this way, the hydration functions and water factors of fibrinogen monolayers were quantitatively evaluated at various pHs. It was revealed that for the lower range of fibrinogen coverage the hydration function were considerably lower than previously obtained for the silica sensor [33]. The lower hydration of fibrinogen monolayers on the gold sensor was attributed to its higher roughness. However, for higher fibrinogen coverage the hydration functions for both sensors became identical exhibiting an universal behavior. By using the hydration functions, the fibrinogen adsorption/desorption runs derived from QCM-D measurements were converted to the Γd vs. the time relationships. This allowed to precisely determine the maximum coverage that varied between 1.6mgm-2 at pH 3.5 and 4.5mgm-2 at pH 7.4 (for ionic strength of 0.15M). These results agree with theoretical eRSA modeling and previous experimental data derived by using ellipsometry, OWLS and TIRF.

These results allow one to develop a method for preparing fibrinogen monolayers of well-controlled coverage and molecule orientation. © 2015 Elsevier B.V.},\nauthor_keywords={Adsorption of fibrinogen on gold;  Fibrinogen adsorption on gold;  Hydration of fibrinogen monolayers on gold;  Kinetic of fibrinogen adsorption on gold;  Mechanisms of fibrinogen adsorption;  QCM-D measurements of fibrinogen adsorption on gold},\nkeywords={Gold;  Hydration;  Ionic strength;  Monolayers, Adsorption kinetics;  Fibrinogen adsorption;  Maximum coverage;  Measurements of;  Molecule orientation;  Random sequential adsorption models;  Theoretical calculations;  Universal behaviors, Adsorption, fibrinogen;  gold;  silicon dioxide;  water;  fibrinogen;  gold, adsorption;  Article;  desorption;  ellipsometry;  hydration;  ionic strength;  mathematical model;  pH;  priority journal;  quantitative analysis;  quartz crystal microbalance;  sensor;  time;  adsorption;  chemistry;  kinetics;  quartz crystal microbalance;  surface property;  thermodynamics, Adsorption;  Fibrinogen;  Gold;  Hydrogen-Ion Concentration;  Kinetics;  Quartz Crystal Microbalance Techniques;  Surface Properties;  Thermodynamics;  Water},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Within this mesh structure, a tracer molecule is allowed to perform a Cauchy random walk with uncorrelated steps. Our analysis shows that the presence of obstacles significantly influences the motion, which in an obstacle-free space would be of a superdiffusive type. At the same time, the selfdiffusive process reveals different anomalous properties, both at the level of a single trajectory realization and after the ensemble averaging. In particular, due to obstacles, the sample mean squared displacement asymptotically grows sublinearly in time, suggesting a non-Markov character of motion.

However, activity fluctuations also appear over a wide range of temporal scales, from days to a few seconds, resulting from the concatenation of a myriad of individual smaller motor events. Furthermore, individuals present di?erent propensity to wakefulness and thus to motor activity throughout the circadian cycle. Are activity fluctuations across temporal scales intrinsically different, or is there a universal description encompassing them? Is this description also universal across individuals, considering the aforementioned variability? Here we establish the presence of universality in motor activity fluctuations based on the empirical study of a month of continuous wristwatch accelerometer recordings. We study the scaling of average fluctuations across temporal scales and determine a universal law characterized by critical exponents α, τ and 1/µ. Results are highly reminiscent of the universality described for the average shape of avalanches in systems exhibiting crackling noise. Beyond its theoretical relevance, the present results can be important for developing objective markers of healthy as well as pathological human motor behavior. © 2013, Instituto de Fisica de Liquidos y Sistemas Biologicos.

This hierarchy of results can be calculated thanks to the α stability of the Gaussian distribution. In this paper we show that it is possible to generalize the model of Gaussian chain to the entire class of α-stable distributions, obtaining the analogous hierarchy of results expressed by the analytical closed-form formulas in the Fourier space. This allows us to establish the α-stable chain model. We begin with reviewing the applications of Levy flights in the context of polymer sciences, which include: chains described by the heavy-tailed distributions of persistence length; polymers adsorbed to the surface; and the chains driven by a noise with power-law spatial correlations. Further, we derive the distribution of segments around the mass center of the α-stable chain and construct the coarse-grained interaction potential between two chains. These results are employed to discuss the model of binary mixture consisting of the α-stable chains. In what follows, we establish the spinodal decomposition condition generalized to the mixtures of the α-stable polymers. This condition is further applied to compare the on-surface phase separation of adsorbed polymers (which are known to be described with heavy-tailed statistics) with the phase separation condition in the bulk. Finally, we predict the four different scenarios of simultaneous mixing and demixing in the two- and three-dimensional systems. © 2015 American Physical Society.},\nkeywords={Chains;  Gaussian distribution;  Mixtures;  Phase separation;  Polymers;  Spinodal decomposition, Alpha-stable distribution;  Effective interactions;  Gaussian chain models;  Heavy-tailed distribution;  Interaction potentials;  Separation condition;  Spatial correlations;  Three dimensional systems, Binary mixtures},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In particular, it shows that a consistent theory should involve general couplings between primary uniaxial and biaxial order parameters. These couplings are only partly accounted for by the standard Landau-de Gennes approach as indicated by molecular theories. The Landau theory of biaxial nematics can be derived in a systematic way from density functional theory, like molecular field. The chapter not only gives a molecular interpretation of the alignment tensor, but also expresses the Landau expansion coefficients in terms of molecular parameters. That gives a bridge between phenomenological phase diagrams and microscopic modelling. One of the most fundamental descriptions of the symmetry change from isotropic to uniaxial and biaxial nematics is offered by the phenomenological Landau theory. © 2015 John Wiley & Sons, Ltd.

In this paper, we analyze spontaneous locomotor activity of healthy individuals recorded in two different conditions: during a week of regular sleep and a week of chronic partial sleep deprivation. After separating activity from rest with a pre-defined activity threshold, we have detected distinct statistical features of duration times of these two states. The cumulative distributions of activity periods follow a stretched exponential shape, and remain similar for both control and sleep deprived individuals. In contrast, rest periods, which follow power-law statistics over two orders of magnitude, have significantly distinct distributions for these two groups and the difference emerges already after the first night of shortened sleep. We have found steeper distributions for sleep deprived individuals, which indicates fewer long rest periods and more turbulent behavior.

We use Gleeson's et al., Phys. Rev. E80, 036107 (2009) algorithm to create clustered networks in which a proportion of individuals is located in fully-connected cliques of certain size. A SIR model is extended to include delayed and imperfect detection of infectious individuals. We also include a combination of responsive (palliative) and preventive (vaccination) treatments and design cost-effective disease control strategies. Cost-benefit analysis is used in combination with epidemiological simulations to identify an optimal radius for a treatment centred upon the symptomatic individual. Three general control strategies occur depending on the relative cost of treatment and prevention. Network topology and, in particular, clustering also affects the applicability of the control strategy. The average path length appears to be more important; the range for the control strategy is wider with the length, but the optimal radius of control also extends. As the proportion of individuals in cliques and therefore the coefficient of clustering is higher, the range of the costs for which control scenario is optimal is greater. This results have important consequences for designing disease control strategies that also satisfy economic optimality criteria.},\nkeywords={Average path length;  Clustered networks;  Control strategies;  Epidemiological simulations;  Infectious disease;  Network topology;  Optimality criteria;  Random network, Cost benefit analysis;  Electric network topology;  Epidemiology, Optimization},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In this paper, we propose a theory of binary systems that results in a relatively simple analytical expression combining arbitrary microscopic potentials into effective interaction. The derivation is based on translating a many-particle Hamiltonian including particle-depletant and depletant-depletant interactions into the occupation field language, which turns the partition function into multiple Gaussian integrals, regardless of what microscopic potentials are chosen. As a result, we calculate the effective Hamiltonian and discuss when our formula is a dominant contribution to the effective interactions. Our theory allows us to analytically reproduce several important characteristics of systems under scrutiny. In particular, we analyze the following: the effective attraction as a demixing factor in the binary systems of Gaussian particles, the screening of charged spheres by ions, which proves equivalent to Derjaguin-Landau-Verwey-Overbeek (DLVO) theory, effective interactions in the binary mixtures of Yukawa particles, and the system of particles consisting of both a repulsive core and an attractive/repulsive Yukawa interaction tail. For this last case, we reproduce the "attraction-through-repulsion" and "repulsion-through-attraction" effects previously observed in simulations. © 2014 American Physical Society.},\nkeywords={Analytical theory;  Colloidal system;  Effective interactions;  Soft particles, colloid, colloid;  Fourier analysis;  normal distribution;  theoretical model, Colloids;  Fourier Analysis;  Models, Theoretical;  Normal Distribution},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Stationary states in single-well potentials can be multimodal. Moreover, a potential well needs to be steep enough in order to produce stationary states. Here it is demonstrated that two-dimensional (2D) systems driven by bivariate α-stable noises are even more surprising than their 1D analogs. In 2D systems, intriguing properties of stationary states originate not only due to heavy tails of noise pulses, which are distributed according to α-stable densities, but also because of properties of spectral measures. Consequently, 2D systems are described by a whole family of Langevin and fractional diffusion equations. Solutions of these equations bear some common properties, but also can be very different. It is demonstrated that also for 2D systems potential wells need to be steep enough in order to produce bounded states. Moreover, stationary states can have local minima at the origin. The shape of stationary states reflects symmetries of the underlying noise, i.e., its spectral measure. Finally, marginal densities in power-law potentials also have power-law asymptotics. © 2014 American Physical Society.},\nkeywords={Bivariate;  Stationary state;  Two-dimensional systems, theoretical model, Models, Theoretical},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Connections between individuals are indispensable for cooperative action of agents building social groups. Moreover, social groups usually evolve and their structure changes over time. Consequently, an underlying network connecting individuals is not static, reflecting an ongoing adaptation to new conditions. The evolution of social connections is influenced by the relative position (hierarchy) of individuals building the system as well as by the availability of resources. We explore this aspect of human ambition by modeling the interplay of social networking and an uneven distribution of external resources. The model naturally generates social hierarchies. Remarkably, this social structure exhibits a rise-and-fall behavior. A well pronounced quasi-periodic dynamics, which is closely associated with the dissipation of resources that are needed to sustain the social links, is revealed. © 2014 The Royal Swedish Academy of Sciences.},\nauthor_keywords={entropy and other measures of information;  fluctuation phenomena;  random processes;  social and economic systems},\nkeywords={Molecular physics;  Physics, External resources;  Fluctuation phenomena;  Measures of information;  Relative positions;  Social and economic systems;  Social connection;  Social hierarchy;  Underlying networks, Random processes},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The work focuses on the dependence between level of the orientational order (degree of environmental crowding) of fibrinogen molecules inside a layer and non-Fickian character of the diffusion process of spherical tracer particles moving within the domain. It is shown that in general particles motion is subdiffusive and strongly anisotropic, and its characteristic features significantly change with the orientational order parameter, concentration of fibrinogens, and radius of a diffusing probe. © 2014 AIP Publishing LLC.},\nkeywords={Computer simulation;  Molecules;  Nematic liquid crystals, Diffusion process;  Gaussian random walk;  Non-Fickian;  Orientational order parameters;  Orientational orderings;  Particles motions;  Spherical tracers;  Tracer diffusion, Anisotropy},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The differences in models affect choice of the strategy only for very cheap treatment and slow spreading disease. However for the combinations of parameters that are important from the epidemiological perspective (high infectiousness and expensive treatment) the models give similar results. Moreover, even where the choice of the strategy is different, the total cost spent on controlling the epidemic is very similar for both models. © 2013 Oleś et al.},\nkeywords={article;  disease control;  disease transmission;  epidemic;  infection control;  infection sensitivity;  mathematical model, Communicable Disease Control;  Communicable Diseases;  Epidemics;  Humans;  Models, Theoretical},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Motivated by Onsager's approach, we extend the theory to fluctuations including Lévy processes. We assume that deviations from Gaussian distributions, which are often observed in non-equilibrium systems, may be described by convoluted Gauss-Lévy distributions and their relation to stationary states by generalized Smoluchowski equations. The central part of the distributions we study here is determined by the Gaussian core with the wings decaying according to a power law characteristic for a Lévy-type contribution to statistics. Furthermore, we develop a generalization of Onsager's theory of linear relaxation processes to those which include statistically independent Gaussian fluctuations and (non-equilibrium) Lévy noises. We apply the generalized version of the fluctuation- dissipation theorem (FDT) to analyze regime of the linear response of the non-equilibrium system driven by Lévy (Cauchy) white noise and subject to thermal (Gaussian) fluctuations. In the last part, applications to non-Maxwellian velocity fluctuations and their relaxations are investigated.},\nkeywords={Fluctuation theory;  Gaussian fluctuations;  Irreversible process;  Nonequilibrium system;  Onsager's theory;  Power-law characteristics;  Smoluchowski equation;  Velocity fluctuations, Relaxation processes;  Statistical mechanics;  White noise, Gaussian distribution},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Resonance behavior can also be observed in non-dynamical systems. The simplest example is a threshold triggered device. It consists of a periodic modulated input and noise. Every time an output crosses the threshold the signal is recorded. Such a digitally filtered signal is sensitive to the noise intensity. There exists the optimal value of the noise intensity resulting in the "most" periodic output. Here, we explore properties of the non-dynamical stochastic resonance in non-equilibrium situations, i.e. when the Gaussian noise is replaced by an α-stable noise. We demonstrate that non-equilibrium α-stable noises, depending on noise parameters, can either weaken or enhance the non-dynamical stochastic resonance. © 2013 The Author(s).},\nkeywords={Classical model;  Combined actions;  Filtered signals;  Noise intensities;  Noise parameters;  Overdamped particles;  Periodic output;  Stochastic resonances, Circuit resonance;  Dynamical systems;  Gaussian noise (electronic), Magnetic resonance},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Fibrinogen molecule shape was approximated by the bead model considering the presence of flexible side arms. Various cases were considered inter alia, the side-on adsorption mechanisms and the simultaneous side-on/end-on adsorption mechanism. The latter mechanisms is pertinent to fibrinogen adsorption at lower pH (below isoelectric point of 5.8) where the entire molecule is positively charged. Extensive calculations enabled one to determine the jamming surface concentration (coverage) of molecules adsorbed under the side-on and end-on orientations as well as the total coverage. For the simultaneous side-on/end-on model the maximum surface concentration was 7.29 × 103 μm-2 corresponding to the protein coverage of 4.12 mg m-2 (without considering hydration). Additionally, the surface blocking functions for different adsorption regimes were determined and analytically approximated for the entire range of coverage by the interpolating polynomials. Using these blocking functions, fibrinogen adsorption kinetics for diffusion controlled transport conditions was evaluated. Comparison of these theoretical results with experimental data was made. It was demonstrated that the simultaneous side-on/end-on model properly reflects the maximum coverage of fibrinogen adsorbed on latex particles determined via the electrokinetic (electrophoretic mobility) and AFM measurements. Also, streaming potential measurements of fibrinogen adsorption kinetics on mica were successfully interpreted in terms of this model. The theoretical results derived in this work have implications for basic science providing information on mechanisms of anisotropic protein adsorption. © 2013 American Chemical Society.},\nkeywords={Adsorption mechanism;  Diffusion controlled;  Fibrinogen adsorption;  Interpolating polynomials;  Iso-electric points;  Random sequential adsorption models;  Streaming potential measurements;  Surface concentration, Adsorption;  Electrophoretic mobility;  Mica;  Molecules, Three dimensional, fibrinogen, adsorption;  article;  chemistry;  pH;  surface property, Adsorption;  Fibrinogen;  Hydrogen-Ion Concentration;  Surface Properties},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Measurements were carried out for pH 3.5 and an ionic strength range of 10 -3 to 0.15 M NaCl. The electrophoretic mobility of latex was determined as a function of the amount of adsorbed fibrinogen (surface concentration). A monotonic increase in the electrophoretic mobility (zeta potential) of the latex was observed, indicating a significant adsorption of fibrinogen on latex for all ionic strengths. No changes in the latex mobility were observed for prolonged time periods, suggesting the irreversibility of fibrinogen adsorption. The maximum coverage of fibrinogen on latex particles was precisely determined using the depletion method. The residual protein concentration after making contact with latex particles was determined by electrokinetic measurements and AFM imaging where the surface coverage of fibrinogen on mica was quantitatively determined. The maximum fibrinogen coverage increased monotonically with ionic strength from 1.8 mg m-2 for 10-3 M NaCl to 3.6 mg m-2 for 0.15 M NaCl. The increase in the maximum coverage was interpreted in terms of the reduced electrostatic repulsion among adsorbed fibrinogen molecules. The experimental data agree with theoretical simulations made by assuming a 3D unoriented adsorption of fibrinogen. The stability of fibrinogen monolayers on latex was also determined in ionic strength cycling experiments. It was revealed that cyclic variations in NaCl concentration between 10-3 and 0.15 M induced no changes in the latex electrophoretic mobility, suggesting that there were no irreversible molecule orientation changes in the monolayers. On the basis of these experimental data, a robust procedure of preparing fibrinogen monolayers on latex particles of well-controlled coverage was proposed. © 2013 American Chemical Society.},\nkeywords={Electrokinetic measurements;  Electrostatic repulsion;  Fibrinogen adsorption;  Microelectrophoretic;  Molecule orientation;  Polystyrene latex particles;  Surface concentration;  Theoretical simulation, Adsorption;  Electrophoretic mobility;  Latexes;  Mica;  Molecules;  Monolayers;  Polystyrenes;  Three dimensional computer graphics;  Zeta potential, Ionic strength, fibrinogen;  latex, adsorption;  article;  chemistry;  colloid;  human;  osmolarity, Adsorption;  Colloids;  Fibrinogen;  Humans;  Latex;  Osmolar Concentration},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In non-cycling (G0-phase) lymphocytes the induction and the repair of excess fragments was measured by means of the premature chromosome condensation (PCC) technique and the distribution of breaks among cells was analysed. The PCC-data were further compared with those reported recently for stimulated lymphocytes at the first post-irradiation mitosis. Our experiments show that a single nuclear traversal by a Fe-ion produced more initial chromatin breakage than one Cr-ion, but after 24 h of repair the number of excess fragments/cell was similar for both ion species. All distributions of aberrations were overdispersed. For low energy Cr-ions, where the track radius is smaller than the radius of the cell nucleus, the data could be well described by a Neyman type A distribution. In contrast, the data obtained for high energy Fe-ions were fitted with a convoluted Poisson-Neyman distribution to account for the fact that the dose is deposited not only in the cell actually traversed but also in neighbouring cells. By applying metaphase analysis a different picture emerged with respect to the aberration yield, i.e. more aberrations were detected in cells exposed to Fe-ions than in those irradiated with Cr-ions. Yet, as observed for non-cycling lymphocytes all aberration distributions generated for metaphase cells were overdispersed. The obtained results are discussed with respect to differences in particle track structure. Additionally, the impact of confounding factors such as apoptosis that affect the number of aberrations expressed in a cell population is addressed. © 2012 COSPAR. Published by Elsevier Ltd.

Accordingly, the response or the generalized susceptibility, which is a function of the unperturbed equilibrium system, can be related to the correlation between spontaneous fluctuations of a given conjugate variable. There have been several attempts to extend the FDT far from equilibrium, introducing new terms or using effective temperatures. Here, we discuss applicability of the generalized FDT to out-of-equilibrium systems perturbed by time-dependent deterministic forces and acting under the influence of white Lévy noise. For the linear and Gaussian case, the equilibrium correlation function provides a full description of the dynamic properties of the system. This is, however, no longer true for non-Gaussian Lévy noises, for which the second and sometimes also the first moments are divergent, indicating absence of underlying physical scales. This self-similar behavior of Lévy noises results in violation of the classical dissipation theorem for the stability index α<2. We show that by properly identifying appropriate variables conjugated to external perturbations and analyzing time-dependent distributions, the generalized FDT can be restored also for systems subject to Lévy noises. As a working example, we test the use of the generalized FDT for a linear system subject to Cauchy white noise. © 2012 Europhysics Letters Association.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Three general strategies emerge: global preventive treatment, local treatment within a neighborhood of certain size and only palliative treatment with no prevention. While the choice between the strategies depends on a relative cost of palliative and preventive treatment, the details of the local strategy and, in particular, the size of the optimal treatment neighborhood depend on the epidemiological factors. The required extent of prevention is proportional to the size of the infection neighborhood, but depends on time till detection and time till treatment in a non-nonlinear (power) law. The optimal size of control neighborhood is also highly sensitive to the relative cost, particularly for inefficient detection and control application.

Being enzymes, they undergo chemical reactions leading to energy conversion and changes of their conformation. Being mechanodevices, they use the chemical energy to perform mechanical work, leading to the phenomena of motion. Over the past 20 years a series of novel experiments (e.g. single molecule observations) has been performed to gain the deeper knowledge about chemical states of molecular motors as well as their dynamics in the presence or absence of an external force. At the same time, many theoretical models have been proposed, offering various insights into the nano-world dynamics. They can be divided into three main categories: mechanochemical models, ratchet models and molecular dynamics simulations. We demonstrate that by combining those complementary approaches a deeper understanding of the dynamics and chemistry of the motor proteins can be achieved. As a working example, we choose kinesin - a motor protein responsible for directed transport of organelles and vesicles along microtubule tracts.},\nkeywords={Chemical energy;  Chemical state;  Directed transport;  External force;  Kinesins;  Large parts;  Mechanical work;  Mechanochemicals;  Microtubules;  Molecular dynamics simulations;  Molecular motors;  Motor proteins;  Operating principles;  Processivity;  Ratchet models;  Single-molecule observation;  Theoretical models, Dynamics;  Energy conversion;  Linear motors;  Molecular dynamics, Proteins},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Rates of transitions between the two branches of the hysteresis curve are modeled with single-barrier kinetics by introducing a real-valued "reaction coordinate" parametrizing the protein's conformational change between the two states of gate tension. The resulting scenario suggests a reanalysis of former experiments with NSVDC channels.},\nkeywords={Positive ions;  Reaction rates, Cation channels;  Conformational change;  Counter-clockwise;  Human erythrocytes;  Hysteresis curve;  Hysteresis cycles;  Phenomenological models;  Reaction coordinates, Hysteresis},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

We present a comprehensive analysis of a two-dimensional model polymer chain, driven by the spatially correlated Gaussian noise, for which we have varied the amplitude and the correlation length. The chain model is based on a bead-spring approach, enriched with a global Lennard-Jones potential and angular interactions. We show that spatial correlations in the noise inhibit the chain geometry dynamics, enhancing the preservation of the polymer shape. This is supported by the analysis of correlation functions of both the module length and angles between neighboring modules, which have been measured for the noise amplitude ranging over three orders of magnitude. Moreover, we have observed the correlation length dependent bead motion synchronization and the spontaneous polymer unfolding, resulting from an interplay between chain potentials and the spatially structured noise. © 2012 American Physical Society.},\nkeywords={Chain geometry;  Chain models;  Comprehensive analysis;  Correlated Gaussian noise;  Correlation function;  Correlation lengths;  Noise amplitude;  Polymer chains;  Spatial correlations;  Spatially correlated noise;  Structured noise;  Three orders of magnitude;  Two dimensional model, Gaussian noise (electronic);  Soil structure interactions, Polymers},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

They are constructed as a 2-dimensional Newman and Watts model (500 × 500 square lattice with additional shortcuts), where the dynamics involves rewiring shortcuts in every time step of the epidemic spread. We assume susceptible-infectious-removed (SIR) model of the disease. We study the behaviour of the epidemic over the range of shortcut probability per underlying bond ø = 0-0.5. We calculate percolation thresholds for the epidemic outbreak, for which numerical results are checked against an approximate analytical model. We find a significant lowering of percolation thresholds on the dynamic network in the parameter range given. The result shows the behaviour of the epidemic on dynamic network is that of a static small world with the number of shortcuts increased by 20.7±1.4 \\%, while the overall qualitative behaviour stays the same. We derive corrections to the analytical model which account for the effect. For both dynamic and static small worlds we observe suppression of the average epidemic size dependence on network size in comparison with the finite-size scaling known for regular lattice. We also study the effect of dynamics for several rewiring rates relative to infectious period of the disease. © 2011 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.},\nkeywords={Analytical model;  Dynamic network;  Epidemic spread;  Finite size scaling;  Infectious period;  Network size;  Numerical results;  ON dynamics;  Parameter range;  Percolation thresholds;  Regular lattice;  Size dependence;  Small world networks;  Small worlds;  Square lattices;  Static and dynamic;  Susceptible-infectious-removed models;  Time step, Behavioral research;  Computer simulation;  Mathematical models;  Models;  Percolation (computer storage);  Percolation (fluids);  Percolation (solid state);  Solvents, Epidemiology},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Amongst statistical theories of nematic liquid crystals, a molecular mean-field model has proven to be quite effective in predicting phase sequences for thermotropic biaxial nematic molecules endowed with D2h symmetry, as a function of the parameters entering their interaction potential [2,3]. This model has highlighted the role of a partially repulsive quadrupolar potential of mean torque in promoting condensed phases. It has been shown that the quadrupolar approximation to the excluded-volume interaction between hard spherocuboids can be written precisely as the superposition of two London interactions: one repulsive and one attractive [4]; furthermore, polar steric interactions have been shown to be capable of inducing orientationally ordered states possibly unexpected [5]. By adapting a numerical code available to the scientific community, we evaluate the analytical excluded volume function for non-convex tetrahedral molecules, modelled as chains of tangent hard spheres. Since this function is overly complicated, we expand it over a suitable set of Symmetry Adapted Wigner Functions (SAWFs).

The asymptotic relation between properly scaled CTRW and fractional diffusion process has been worked out via various approaches widely discussed in literature. Here, we focus on a correspondence between CTRWs and time and space fractional diffusion equation stemming from two different methods aimed to accurately approximate anomalous diffusion processes. One of them is the Monte Carlo simulation of uncoupled CTRW with a Lévy α-stable distribution of jumps in space and a one-parameter Mittag-Leffler distribution of waiting times. The other is based on a discretized form of a subordinated Langevin equation in which the physical time defined via the number of subsequent steps of motion is itself a random variable. Both approaches are tested for their numerical performance and verified with known analytical solutions for the Green function of a space-time fractional diffusion equation. The comparison demonstrates a trade off between precision of constructed solutions and computational costs. The method based on the subordinated Langevin equation leads to a higher accuracy of results, while the CTRW framework with a Mittag-Leffler distribution of waiting times provides efficiently an approximate fundamental solution to the FFPE and converges to the probability density function of the subordinated process in a long-time limit. © 2010 American Institute of Physics.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In the case of X-rays the energy is deposited uniformly within the cell nucleus and produces damages in a purely stochastic manner. In contrast, for particles the energy is deposited inhomogeneously along the ion trajectory and the local dose decays with the square radial distance from the center of the track. This nonuniformity affects the yield and the distribution of aberrations among cells. Moreover, after high LET exposure a relationship between the aberration yield and cell cycle delay was observed. In this study, we present a detailed analysis of the distribution of aberrations in human lymphocytes reaching mitosis at early and later times after low and high LET exposure. Aberration data were fit to stochastic distributions demonstrating that the delay is related to the number of particle traversals per cell nucleus. To further elucidate this relationship, we introduce a Monte Carlo phenomenological model which incorporates the number of particle hits per nucleus. This value was derived by fitting theoretical distributions to the experimental data. Additionally, the probability that a cell traversed by a particle reaches mitosis at a given time was calculated. The analysis of biological data and numerical simulations clearly show the impact of the track structure on the formation of chromosome aberrations and their distribution among cells. © 2010 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The efficiency of the motor is defined as the ratio of the power exerted in the uphill motion with respect to the energy influx from the depot. We analyze the efficiency of this system by adapting the motor model in which only the internal motion includes inertia, whereas the motion of its center of mass becomes overdamped. Based on the numerical simulations of the center of mass trajectories and analysis of directed fluxes of motor particles moving along a one-dimensional track, we derive thermodynamic estimates of the motor efficiency as a function of the opposing force.},\nkeywords={Center of mass;  Chemical energy;  Energy influx;  Energy reservoirs;  Fluctuating forces;  Internal motion;  Living cell;  Mechanical work;  Motor efficiencies;  Motor models;  Motor particles;  Nano-scale machines;  Numerical simulation;  Stepper motor;  Uphill motion, Computer simulation;  Energy conversion;  Physics;  Stepping motors;  Wavelet transforms, Flight dynamics},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

Applying analytical arguments and numerical methods, we demonstrate that the presence of long waiting times distributed according to a power-law distribution with a diverging mean leads to very general asymptotic properties of the survival probability. The observed survival probability asymptotically decays like a power law whose form is not affected by the value of the exponent characterizing the power law jump length distribution. It is demonstrated that this behavior is typical of and generic for systems exhibiting long waiting times. We also show that the survival probability has a universal character not only asymptotically, but also at small times. Finally, it is indicated which properties of the first passage time density are sensitive to the exact value of the exponent characterizing the jump length distribution. © 2010 American Institute of Physics.},\nkeywords={Asymptotic properties;  First-passage-time density;  Fractional diffusion equation;  Jump length;  Potential wells;  Power law;  Power law distribution;  Survival probabilities;  Waiting time, Asymptotic analysis;  Competition;  Numerical methods, Probability distributions},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The competition between anomalously long jumps and long waiting times leads to a very general kind of behavior.

The presence of long jumps which can be distributed according to nonsymmetric heavy tailed distributions does not affect asymptotic properties of the survival probability. Therefore, the probability of finding a random walker within a domain of motion decays asymptotically according to the universal pattern derived from the Mittag-Leffler function, which describes decay of single modes in subdiffusive dynamics.},\nkeywords={Absorbing boundaries;  Asymptotic properties;  Decay patterns;  Domain of motion;  Finite intervals;  Heavy-tailed distribution;  Mittag-Leffler functions;  Nonsymmetric;  Power law distribution;  Random walkers;  Single mode;  Survival probabilities;  Waiting time, Asymptotic analysis;  Physics;  Probability density function, Probability distributions},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

Analogously, the jump length is adjusted to the shortest or to the longest jump length.

In the decoupled case, with power-law distributed waiting times and jump lengths, the CTRW scenario is asymptotically described by the double (space and time) fractional Fokker-Planck equation. Properties of a system described by such an equation are determined by the subdiffusion parameter and the jump length exponent. Nevertheless, the stationary state is determined solely by the jump length distribution and the potential. The waiting time distribution determines only the rate of convergence to the stationary state. Here, we inspect the competition between long waiting times and long jumps and how this competition is reflected in the way in which a stationary state is reached. In particular, we show that the distance between a time-dependent and a stationary solution changes in time as a double power law. © 2010 IOP Publishing Ltd and SISSA.},\nauthor_keywords={Diffusion;  Stochastic particle dynamics (theory);  Stochastic processes (experiment);  Stochastic processes (theory)},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Numerical simulation of the Monte Carlo type enabled one to determine the dependence of the surface blocking function (available surface function) on the protein coverage. These numerical results were interpolated using analytical functions based on a polynomial expansion. The dependence of the jamming coverage on the size of the simulation area was also determined. By an extrapolation of these results to the infinite area size, the maximum surface concentration of fibrinogenfor the side-on adsorption was determined to be 2.26 × 10 3 μm -2. This corresponds to a jamming coverage θ∞ of 0.29. It was shown that the blocking function can well be approximated in the limit of highcoverage by the dependence C(θ∞ - θ) 4. Using this interpolating expression, the kinetics of fibrinogen adsorption under convection and diffusion transportconditions were evaluated for various bulk concentrations of the protein. These kinetic curves were derived by numericallysolving the mass transport equation in the bulk with the blocking function used as a nonlinear boundary condition at the interface. It was shown that our theoretical results are in agreement with experimental kinetic data obtained by AFM, ellipsometry, and other techniques for hydrophilic surfaces in thelimit of low bulk fibrinogen concentration. © 2010 American Chemical Society.},\nkeywords={AFM;  Analytical functions;  Bulk concentration;  Convection and diffusion;  Experimental kinetics;  Fibrinogen adsorption;  Fibrinogen concentration;  Hydrophilic substrate;  Hydrophilic surfaces;  Kinetic curves;  Linear chain;  Mass transport equation;  MONTE CARLO;  Non-linear boundary conditions;  Numerical results;  Numerical simulation;  Polynomial expansion;  Random sequential adsorption models;  Surface blocking;  Surface concentration;  Surface functions;  Theoretical result, Hydrophilicity;  Jamming;  Nonlinear equations, Adsorption, fibrinogen, adsorption;  article;  chemical phenomena;  chemical structure;  chemistry;  kinetics;  protein conformation;  surface property, Adsorption;  Fibrinogen;  Hydrophobic and Hydrophilic Interactions;  Kinetics;  Models, Molecular;  Protein Conformation;  Surface Properties},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Here we explore in details the fact that this kind of qualification, if applied straightforwardly, may be misleading: there are anomalous transport motions revealing perfectly "normal" diffusive character (x2 (t) t) yet being non-Markov and non-Gaussian in nature. We use recently developed framework of Monte Carlo simulations which incorporates anomalous diffusion statistics in time and space and creates trajectories of such an extended random walk.

We assume that the elements (energy depots) are provided at discrete times with packets of chemical energy which is subsequently converted into acceleration of motion. In contrast to the mechanical white noise which is incorporated in the equations of mechanical motion and has no preferred direction, the energetic noise, as discussed in this study, is directed and it does not reverse the direction of mechanical motion. We characterize the effective noise acting on the particles and show that the stochastic energy supply may be modeled as a shot-noise driven Ornstein-Uhlenbeck process in energy which finally results in fluctuations of the velocity. We study the energy and velocity distributions for different regimes and estimate the crossover time from ballistic to diffusion motion. Further we investigate the dynamics of swarms and find a transition from translational to rotational motion depending on the rate of the shot noise. © 2009 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.},\nkeywords={Brownian Dynamics;  Chemical energy;  Diffusion motion;  Energy supplies;  Individual particles;  Mechanical motions;  Ornstein-Uhlenbeck process;  Rotational motion;  Two-dimension, Agriculture;  Brownian movement;  Chemical elements;  Dynamics;  Equations of motion;  Food supply;  Shot noise;  Stochastic systems, Time and motion study},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

An additional assumption about the existence of timescale separation between the dynamics of the measured observable and the typical timescale of the noise allows external fluctuations to be modeled as temporally uncorrelated and therefore white. However, in many natural phenomena the assumptions concerning the above mentioned properties of 'Gaussianity' and 'whiteness' of the noise can be violated. In this context, in contrast to the spatiotemporal coupling characterizing general forms of non-Markovian or semi-Markovian Lévy walks, so called Lévy flights correspond to the class of Markov processes which can still be interpreted as white, but distributed according to a more general, infinitely divisible, stable and non-Gaussian law. Lévy noise-driven non-equilibrium systems are known to manifest interesting physical properties and have been addressed in various scenarios of physical transport exhibiting a superdiffusive behavior. Here we present a brief overview of our recent investigations aimed at understanding features of stochastic dynamics under the influence of Lévy white noise perturbations. We find that the archetypal phenomena of noise-induced ordering are robust and can be detected also in systems driven by memoryless, non-Gaussian, heavy-tailed fluctuations with infinite variance. © 2009 IOP Publishing Ltd.},\nauthor_keywords={Driven diffusive systems (theory);  Stochastic particle dynamics(theory);  Stochastic processes (theory);  Transport processes/heat transfer (theory)},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

We study the progression of mammalian cells through the cell cycle after exposure. The analysis reveals a prolonged block of damaged cells in the G2 phase.

We present the results of radiation-induced fragmentation of plasmid DNA analyzed by atomic force microscopy (AFM) to allow the visualization of individual DNA molecules. Linear ΦX174 plasmid DNA was exposed to a wide range of doses of low-LET X rays and high-LET carbon, nickel and uranium ions. The induced DNA fragments were detected and measured based on the recorded AFM images and fragment length distributions were derived for each radiation type and dose. The results show a dose- and radiation type-dependent DNA fragmentation with a significantly larger fraction of short fragments produced by high-LET radiation compared to X rays. This can be considered as experimental evidence of DSB clustering due to inhomogeneous energy deposition at the level of the plasmid DNA molecule. Additionally, the experimentally derived fragment profiles were compared and found to be in agreement with the prediction of a model simulating the fragmentation of DNA molecules induced by radiation. © 2009 by Radiation Research Society.},\nkeywords={carbon;  nickel;  plasmid DNA;  uranium;  DNA, article;  atomic force microscopy;  controlled study;  DNA fragmentation;  double stranded DNA break;  ionizing radiation;  priority journal;  radiation dose;  X ray;  chemical model;  chemical structure;  chemistry;  computer simulation;  conformation;  DNA damage;  methodology;  radiation exposure;  radiation response;  ultrastructure, Computer Simulation;  DNA;  DNA Damage;  Dose-Response Relationship, Radiation;  Microscopy, Atomic Force;  Models, Chemical;  Models, Molecular;  Nucleic Acid Conformation;  Radiation Dosage},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Our model is a stochastic machine able to acquire energy from the environment and convert it into kinetic energy of motion. We present characteristic features and demonstrate the possibility of tuning these motors by adapting the mean frequency of the discrete energy inputs, which are described as a special shot noise. In particular, the effect of stochastically driven directionality and uphill flux in systems acquiring energy from the shot noise is analyzed.

Here we explore in details the fact that this kind of qualification, if applied straightforwardly, may be misleading: there are anomalous transport motions revealing perfectly "normal" diffusive character (x2 (t) t) yet being non-Markov and non-Gaussian in nature. We use recently developed framework of Monte Carlo simulations which incorporates anomalous diffusion statistics in time and space and creates trajectories of such an extended random walk. For special choice of stability indices describing statistics of waiting times and jump lengths, the ensemble analysis of anomalous diffusion is shown to hide temporal memory effects which can be properly detected only by examination of formal criteria of Markovianity (fulfillment of the Chapman-Kolmogorov equation). © 2009 The American Physical Society.},\nkeywords={Anomalous behavior;  Anomalous diffusion;  Anomalous transport;  Central moments;  Chapman-Kolmogorov equation;  Diffusive behavior;  Jump length;  Linear dependence;  Monte Carlo Simulation;  Non-Gaussian;  ON time;  Random Walk;  Stability indices;  Temporal memory;  Time and space;  Time dependence;  Waiting time, Computational complexity;  Computer simulation;  Monte Carlo methods;  Special effects;  Stability criteria, Equations of motion},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Within the model we focus on a study of vectors' properties and on the interplay between vectors' characteristics and their dispersal patterns.

We also search for a type of a random walk which leads to the highest severity of epidemics. On the basis of numerical simulations we can conclude that from the whole considered class of random walks some are favored over others.

If the process is Markovian, its transition probability does not depend on the history of the process and it fulfills the Smoluchowski-Chapman-Kolmogorov equation. A practical verification of these two criteria is not always possible or fully conclusive. Therefore, we present an additional method which can be used to confirm the simplest version of Markovianity. This method is based on the properties of sums of independent random variables. We apply the presented method to prove the increment dependent character of an anomalous process combining long waiting times with long jumps. Such a process, despite being non-Markovian in nature, due to a competition between long waiting times and long jumps, can reveal 'normal' behavior. We also demonstrate that this anomalous process breaks the ergodicity in the weak sense. Finally, we apply the suggested method to some experimental time series proving their Markovian nature for small timescales. © 2009 IOP Publishing Ltd and SISSA.},\nauthor_keywords={Ergodicity breaking (theory);  Stochastic particle dynamics (theory);  Stochastic processes (experiment);  Stochastic processes (theory)},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

An additional assumption about the existence of timescale separation between the dynamics of the measured observable and the typical timescale of the noise allows external fluctuations to be modeled as temporally uncorrelated and therefore white. However, in many natural phenomena the assumptions concerning the above mentioned properties of 'Gaussianity' and 'whiteness' of the noise can be violated. In this context, in contrast to the spatiotemporal coupling characterizing general forms of non-Markovian or semi-Markovian Lévy walks, so called Lévy flights correspond to the class of Markov processes which can still be interpreted as white, but distributed according to a more general, infinitely divisible, stable and non-Gaussian law. Lévy noise-driven non-equilibrium systems are known to manifest interesting physical properties and have been addressed in various scenarios of physical transport exhibiting a superdiffusive behavior. Here we present a brief overview of our recent investigations aimed at understanding features of stochastic dynamics under the influence of Lévy white noise perturbations. We find that the archetypal phenomena of noise-induced ordering are robust and can be detected also in systems driven by memoryless, non-Gaussian, heavy-tailed fluctuations with infinite variance. © 2009 IOP Publishing Ltd.},\nauthor_keywords={Driven diffusive systems (theory);  Stochastic particle dynamics(theory);  Stochastic processes (theory);  Transport processes/heat transfer (theory)},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The infection spreads on a two-dimensional lattice with the fixed nearest neighbour connections. In addition, long-range dynamical links are formed by moving agents (vectors). Vectors perform random walks, with step length distributed according to a thick-tail distribution. Two distributions are considered in this paper, an a-stable distribution describing self-similar vector movement, yet characterized by an infinite variance and an exponential power characterized by a large but finite variance. Such long-range interactions are hard to track and make control of epidemics very difficult. We also allowed for cryptic infection, whereby an infected individual on the lattice can be infectious prior to showing any symptoms of infection or disease. To account for such cryptic spread, we considered a control strategy in which not only detected, i.e. symptomatic, individuals but also all individuals within a certain control neighbourhood are treated upon the detection of disease. We show that it is possible to eradicate the disease by using such purely local control measures, even in the presence of long-range jumps. In particular, we show that the success of local control and the choice of the optimal strategy depend in a non-trivial way on the dispersal patterns of the vectors. By characterizing these patterns using the stability index of the a-stable distribution to change the power-law behaviour or the exponent characterizing the decay of an exponential power distribution, we show that infection can be successfully contained using relatively small control neighbourhoods for two limiting cases for long-distance dispersal and for vectors that are much more limited in their dispersal range. © 2009 The Royal Society.},\nauthor_keywords={Disease spread;  Dispersal patterns;  Epidemiological control;  Epidemiological modelling;  Stochastic modelling},\nkeywords={Stochastic control systems;  Vectors, Disease spread;  Dispersal patterns;  Epidemiological control;  Epidemiological modelling;  Stochastic modelling, Disease control, alpha stable distribution;  article;  control strategy;  dispersion;  epidemic;  infection control;  mathematical analysis;  mathematical model;  mathematical variable;  nonhuman;  normal distribution;  random walk;  vector movement},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

When the accumulated exposure is larger than the individual's resistance, an agent becomes infectious and consequently introduces a new source of an epidemic which is capable of passing the disease further.

In the second part of our presentation we consider applications of ABM to ratchet systems with different forms of differentiable potentials. Both analytical and numerical evaluations are discussed for three cases of sinusoidal, staircaselike and Mateos ratchet potentials, also with the additional loads modelled by tilted potential structure. In addition, stochastic character of the kinetics is investigated by considering perturbation by Gaussian white noise which is shown to be responsible for driving the directionality of the asymptotic flux in the ratchet. This stochastically driven directionality effect is visualized as a strong nonmonotonic dependence of the statistics of the right versus left trajectories of motion leading to a net current of particles. Possible applications of the ratchet systems to molecular motors are also briefly discussed. © 2008 Springer.},\nkeywords={Active Brownian particles;  Additional loads;  Brownian Motion models;  Brownian motions;  Energy of motions;  Gaussian white noises;  Kinetic;  Molecular motors;  Nonmonotonic dependences;  Numerical evaluations;  Potential structures;  Ratchet potentials;  Stochastic, Applications;  White noise, Brownian movement},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The dynamics of tumor and immune cells populations is based on the generic Michaelis-Menten kinetics depicting interaction and competition between the tumor and the immune system. The appropriate phenomenological equation modeling cell-mediated immune surveillance against cancer is of the predator-prey form and exhibits bistability within a given choice of the immune response-related parameters. Under the influence of weak external fluctuations, the model may be analyzed in terms of a stochastic differential equation bearing the form of an overdamped Langevin-like dynamics in the external quasi-potential represented by a double well. We analyze properties of the system within the range of parameters for which the potential wells are of the same depth and when the additional perturbation, modeling a periodic treatment, is insufficient to overcome the barrier height and to cause cancer extinction. In this case the presence of a small amount of noise can positively enhance the treatment, driving the system to a state of tumor extinction. On the other hand, however, the same noise can give rise to return effects up to a stochastic resonance behavior. This observation provides a quantitative analysis of mechanisms responsible for optimization of periodic tumor therapy in the presence of spontaneous external noise. Studying the behavior of the extinction time as a function of the treatment frequency, we have also found the typical resonant activation effect: For a certain frequency of the treatment, there exists a minimum extinction time. © 2008 Springer.},\nkeywords={Barrier heights;  Bi-stability;  Cancer growths;  Double wells;  External noises;  External-;  Extinction times;  Host organisms;  Immune cells;  Immune responses;  Immune surveillances;  Immune systems;  Langevin;  Modeling;  Periodic;  Phenomenological equations;  Potential wells;  Quantitative analyses;  Resonant activations;  Resonant effects;  Stochastic differential equations;  Stochastic resonances;  Tumor therapies, Differential equations;  Dynamics;  Immunology;  Population statistics;  Resonance;  Stochastic models;  Stochastic programming;  Tumors, Mathematical models},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The integration of experimental constraints into the model calculations changes the resulting distributions strongly.

Due to the nonthermal character of the driving noise, the particle exhibits a motion with a preferred direction. The additional periodic modulation of the noise asymmetry changes the behavior of the static "Lévy ratchet." For the fast rate of the noise asymmetry modulation, the Lévy ratchet behaves like the one driven by the symmetric α -stable noise. When the modulation period is larger, the nontrivial effects of the noise asymmetry on the behavior of the Lévy ratchet are visible. In particular, the current inversion is observed in the system at hand.

Here we employ random search strategies to identify all possible links, representing direct or indirect interactions between individuals building up the system. In order to recognize all contacts, the searcher performs symmetric Lévy flights onto the accessible area. We investigate the influence of local and non-local information, the exponent characterizing asymptotic behavior of Lévy flights, boundary conditions, density of links and type of a search strategy on the efficiency of the search process. Monte Carlo examination of the suggested model reveals that the efficiency of the search process is sensitive to the type of boundary conditions. Depending on the assumed type of boundary conditions, efficiency of the search process can be a monotonic or non-monotonic function of the exponents characterizing asymptotic behavior of Lévy flights. Consequently, among the whole spectrum of exponents characterizing the power law behavior of jumps' length, there exist distinguished values of stability index representing the most efficient search processes. These exponents correspond to extreme (minimal or maximal) or intermediate values of stability index associated with Gaussian, maximally heavy-tailed or Cauchy-like strategies, respectively. © 2008 Elsevier B.V.

Due to the nonthermal character of the Lévy noise, the particle exhibits a motion with a preferred direction even in the absence of whatever additional time-dependent forces. The examination of the Lévy ratchet has to be based on the characteristics of directionality which are different from typically used measures such as mean current and the dispersion of particle positions, since these become inappropriate when the moments of the noise diverge. To overcome this problem, we discuss robust measures of directionality of transport such as the position of the median of the particle displacement distribution characterizing the group velocity and the interquantile distance giving the measure of the distribution width. Moreover, we analyze the behavior of splitting probabilities for leaving an interval of a given length, unveiling qualitative differences between the noises with Lévy indices below and above unity. © 2008 The American Physical Society.},\nkeywords={Light velocity;  Probability distributions, Group velocities;  Mean currents;  Non-thermal;  Particle displacements;  Periodic potentials;  Qualitative differences;  Spatial symmetries;  Time-dependent, Risk assessment},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

A prototype of such behavior can be found in lyotropic systems-a mixture of potassium laurate, 1-decanol, and D2 O, where distribution of the micellar shape adjusts to actual equilibrium conditions. Further examples of materials with the biaxial nematic phase, where molecular shape is subject to fluctuations, are thermotropic materials composed of flexible trimericlike or tetrapodlike molecular units. Our calculations show that the Gaussian equilibrium distribution of the variables describing molecular shape (dispersion force) anisotropy gives rise to new classes of the phase diagrams, absent in the original model. Depending on properties of the shape fluctuations, the stability of the biaxial nematic phase can be either enhanced or depressed, relative to the uniaxial nematic phases. In the former case the splitting of the Landau point into two triple points with a direct phase transition line from isotropic to biaxial phase is observed. © 2007 The American Physical Society.},\nkeywords={Gaussian distribution;  Mathematical models;  Molecular structure;  Random processes;  Software prototyping;  Tensors, Biaxial nematic phase;  Molecular shape anisotropy, System stability},\ncorrespondence_address1={Longa, L.; Department of Statistical Physics, Marian Smoluchowski Institute of Physics, Jagiellonian University, Reymonta 4, Kraków, Poland; email: longa@th.if.uj.edu.pl},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Our primary goal was a pedagogical exposition of fundamental equilibrium properties of isolated polymers in dilutions with a model that contains many features of real materials. The polymer was chosen to be a three-dimensional chain of N identical beads (monomers) without internal structure. Each monomer interacted with its two neighbors by a harmonic potential, which modeled a chemical bond. Additionally all monomers within a chain were assumed to interact through the Lennard-Jones (LJ) potential. Interaction with solvent and with other polymers was introduced using Langevin forces. Analyzing internal energy per polymer and radius of gyration as function of temperature we observed a rapid globule to coil phase transition. Also we studied clastic properties of single polymer chain for temperatures below the transition and identified three regions with different elastic behavior. Typical chain lengths in our simulations ranged from 100 to 1000 monomers. The elaborated software package can easily be modified to study e.g. the effect of polymer stiffness on thermodynamic behavior.},\nkeywords={Chain length;  Dilution;  Molecular interactions;  Molecular modeling;  Monomers;  Polymers;  Software packages;  Solvents, Langevin forces;  Lennard-Jones (LJ) potential;  Lennard-Jones polymers, Molecular dynamics},\ncorrespondence_address1={Cieśla, M.; Department of Statistical Physics, M.

Materials and methods: Normal human fibroblasts (AG01522C) were exposed in G0/G1 to either 11 MeV u-1 C ions (LET = 153.5 keV μm-1) or 9.9 MeV u-1 Ni ions (LET = 2455 keV μm-1), subcultured in medium containing 5-Bromo-2'-deoxyuridine (BrdU) and at multiple time-points post-irradiation the yield of chromosomal damage, the mitotic index and the cumulative BrdU-labelling index were determined. Furthermore, a mathematical approach was used to analyse the entire cell population. Results: Following high LET exposure normal fibroblasts suffer a transient delay into S-phase and into mitosis as well as a prolonged, probably permanent cell cycle arrest in the initial G0/G1-phase. Cells that reach the first mitosis at early times carried less aberrations than those collected at later times indicating a relationship between cell cycle delay and the number of aberrations. However, with respect to the whole cell population, only a few aberrant fibroblasts are able to progress to the first mitosis. For all endpoints studied the relative biological effectiveness (RBE) of C ions is in the range of 2 - 4, while for Ni ions RBE < 1 is estimated. In contrast, when compared on a per particle basis Ni ions with the higher ionization density were found to be more effective. Conclusions: Detailed analysis of the data demonstrates that the number of fibroblasts at risk for neoplastic transformation is significantly reduced by a chronic cell cycle arrest in the initial G0/G1-phase and, for the first time, the LET-dependence of this effect has been shown. © 2007 Informa UK Ltd.},\nauthor_keywords={Biological dosimetry;  Cell cycle effects;  Chromosome aberrations;  High LET radiation;  Human fibroblasts;  Relative biological effectiveness (RBE)},\nkeywords={carbon;  nickel, article;  cell cycle arrest;  cell cycle G0 phase;  cell cycle G1 phase;  cell cycle S phase;  cell population;  chromosome aberration;  chromosome damage;  controlled study;  fibroblast;  human;  human cell;  linear energy transfer;  mathematical analysis;  mitosis;  mitosis index;  normal human;  priority journal;  relative biologic effectiveness, Bromodeoxyuridine;  Carbon;  Cell Cycle;  Cell Death;  Cells, Cultured;  Chromosome Aberrations;  Dose-Response Relationship, Radiation;  Fibroblasts;  G0 Phase;  G1 Phase;  Humans;  Ions;  Linear Energy Transfer;  Mitosis;  Nickel;  Radiation-Sensitizing Agents;  Relative Biological Effectiveness;  Time Factors},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The behavior of escaping trajectories from one well to another is investigated by pointing to the special character that underpins the noise-induced discontinuity which is caused by the generalized Brownian paths that jump beyond the barrier location without actually hitting it. This fact implies that the boundary conditions for the mean first passage time (MFPT) are no longer determined by the well-known local boundary conditions that characterize the case with normal diffusion. By numerically implementing properly the set up boundary conditions, we investigate the survival probability and the average escape time as a function of the corresponding Lévy white noise parameters. Depending on the value of the skewness β of the Lévy noise, the escape can either become enhanced or suppressed: a negative asymmetry parameter β typically yields a decrease for the escape rate while the rate itself depicts a non-monotonic behavior as a function of the stability index α that characterizes the jump length distribution of Lévy noise, exhibiting a marked discontinuity at α=1. We find that the typical factor of 2 that characterizes for normal diffusion the ratio between the MFPT for well-bottom-to-well-bottom and well-bottom-to-barrier-top no longer holds true. For sufficiently high barriers the survival probabilities assume an exponential behavior versus time. Distinct non-exponential deviations occur, however, for low barrier heights. © 2007 The American Physical Society.},\nkeywords={Asymptotic stability;  Boundary conditions;  Brownian movement;  Probability;  Trajectories;  White noise, Brownian particles;  Brownian path;  Lévy white noise parameters;  Mean first passage time (MFPT), Alpha particles},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In the present study we focus on the distributions of chromosome aberrations induced in human peripheral blood lymphocytes after exposure to 990 MeV/u Fe ions (LET = 155 keV/μm) or X-rays. For the analysis three different types of distributions were applied, namely a Poisson distribution, a compound Poisson-Poisson (Neyman type A) distribution and a convoluted Poisson-Neyman distribution. The analysis showed that after low LET radiation the distribution of aberrations can be well described by Poisson statistics, reflecting a simple random distribution of damages as expected according to the homogeneous pattern of energy depositions. In contrast, for particles the energy is deposited spatially very inhomogeneous and concentrated along the ion trajectories. After exposure to high energy, high LET particles where the track radius is much larger than the cell nucleus, best fits to the data were achieved by a convoluted Poisson-Neyman statistics. The analysis indicates that, under this exposure condition, the distribution of aberrations is determined by two independent components. The first component is determined by the damage induced by a center of the tracks and follows the Neyman distribution. The second component is determined by the overlapping part of tracks which in the case of very high energetic particles leads to a "photon-like" background dose and is thus characterized by a Poisson distribution. © 2007 COSPAR.},\nauthor_keywords={Chromosome aberrations;  Ionizing radiation;  Track structure},\nkeywords={Blood;  Characterization;  Poisson distribution;  Radiation effects;  Statistical methods;  X rays, Chromosome aberrations;  Energetic particles;  Energy deposition;  Statistical distribution;  Track structure, Chromosomes},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

We have numerically analyzed effects of the addition of external noise to a dynamical system representing a bistable over-damped oscillator and detected constructive influence of noise in the phenomena of resonant activation (RA), stochastic resonance (SR), dynamical hysteresis and noiseinduced stability (NES), We have documented that all above-mentioned effects can be observed in the very same system, although for slightly different regimes of parameters characterizing external periodic driving or (and) noise.

The behavior of escaping trajectories from one well to another is investigated by pointing to the special character that underpins the noise-induced discontinuity which is caused by the generalized Brownian paths that jump beyond the barrier location without actually hitting it. This fact implies that the boundary conditions for the mean first passage time (MFPT) are no longer determined by the well-known local boundary conditions that characterize the case with normal diffusion. By numerically implementing properly the set up boundary conditions, we investigate the survival probability and the average escape time as a function of the corresponding Lévy white noise parameters. Depending on the value of the skewness β of the Lévy noise, the escape can either become enhanced or suppressed: a negative asymmetry parameter β typically yields a decrease for the escape rate while the rate itself depicts a non-monotonic behavior as a function of the stability index α that characterizes the jump length distribution of Lévy noise, exhibiting a marked discontinuity at α=1. We find that the typical factor of 2 that characterizes for normal diffusion the ratio between the MFPT for well-bottom-to-well-bottom and well-bottom-to-barrier-top no longer holds true. For sufficiently high barriers the survival probabilities assume an exponential behavior versus time. Distinct non-exponential deviations occur, however, for low barrier heights. © 2007 The American Physical Society.},\nkeywords={Asymptotic stability;  Boundary conditions;  Brownian movement;  Probability;  Trajectories;  White noise, Brownian particles;  Brownian path;  Lévy white noise parameters;  Mean first passage time (MFPT), Alpha particles},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Our primary goal was a pedagogical exposition of fundamental equilibrium properties of isolated polymers in dilutions with a model that contains many features of real materials. The polymer was chosen to be a three-dimensional chain of N identical beads (monomers) without internal structure. Each monomer interacted with its two neighbors by a harmonic potential, which modeled a chemical bond. Additionally all monomers within a chain were assumed to interact through the Lennard-Jones (LJ) potential. Interaction with solvent and with other polymers was introduced using Langevin forces. Analyzing internal energy per polymer and radius of gyration as function of temperature we observed a rapid globule to coil phase transition. Also we studied clastic properties of single polymer chain for temperatures below the transition and identified three regions with different elastic behavior. Typical chain lengths in our simulations ranged from 100 to 1000 monomers. The elaborated software package can easily be modified to study e.g. the effect of polymer stiffness on thermodynamic behavior.},\nkeywords={Chain length;  Dilution;  Molecular interactions;  Molecular modeling;  Monomers;  Polymers;  Software packages;  Solvents, Langevin forces;  Lennard-Jones (LJ) potential;  Lennard-Jones polymers, Molecular dynamics},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

The robustness of the SR is examined by use of standard measures within a continuous and a two-state description of the system.

We show that delay in detection of infectious individuals and presence of long-range links are the most important factors determining the cost. However, the details of long-range links are usually the least-known element of the social interactions due to their occasional character and potentially short life-span. We show that under some conditions on the probability of disease spread, it is advisable to attempt to track those links, even if this involves additional costs. Thus, collecting some additional knowledge about the network structure might be beneficial to ensure a successful and cost-effective control.},\nkeywords={Cost effectiveness;  Disease control;  Epidemiology;  Information retrieval;  Knowledge acquisition;  Probability, Epidemics;  Network structure;  Social interactions, Economic and social effects},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

The robustness of the SR is examined by use of standard measures within a continuous and a two-state description of the system. Since the α-stable noises are characterized by a whole set of parameters, our research focuses on the analysis of the influence of noise parameters on a shape of the signal-to-noise ratio and spectral power amplification curves, revealing presence of the SR in the system at hand. Examination of the driving noise asymmetry indicates that the resonant response weakens when the symmetric noises with a decreasing value of the stability index α are applied.},\nkeywords={Acoustic noise;  Amplification;  Mathematical models;  Parameter estimation;  Random processes;  Robustness (control systems);  Signal to noise ratio, Spectral power amplification;  State description;  Stochastic resonance (SR), Resonance},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

Its intrinsic symmetry properties are exploited to restrict the relevant ranges of coupling constants. Further on, properties of the model are thoroughly investigated by means of bifurcation theory as proposed by Kayser and Raveché [Phys. Rev. A 17, 2067 (1978)] and Mulder [Phys. Rev. A 39, 360 (1989)]. As a first step toward this goal, the bifurcation theory is applied to a general formulation of density functional theory in terms of direct correlation functions. On a general formal level, the theory is then analyzed to show that the bifurcation points from the reference, high-symmetry equilibrium phase to a low-symmetry structure depend only on the properties of the one-particle distribution function and the direct pair correlation function of the reference phase. The character of the bifurcation (whether spinodal, critical, tricritical, isolated Landau point, etc.) depends, in addition, on a few higher-order direct correlation functions. Explicit analytical results are derived for the case when only the leading L=2 terms of the potential (mean-field analysis) or of the direct pair correlation function expansion in the symmetry-adapted basis are retained. Formulas are compared with the numerical calculations for the mean-field, momentum L=2 potential model, in which case they are exact. In particular, bifurcations from the isotropic and uniaxial nematic to the biaxial nematic phases are discussed. The possibility of the recently reported nematic uniaxial-nematic biaxial tricritical point [A. M. Sonnet, E. G. Virga, and G. E. Durand, Phys. Rev. E 67, 061701 (2003)] is analyzed as well. © 2005 The American Physical Society.},\nkeywords={Biaxial nematic phases;  Coupling model;  High-symmetry equilibrium phase;  Isotropics, Bifurcation (mathematics);  Correlation methods;  Probability density function;  Theorem proving, Nematic liquid crystals},\ncorrespondence_address1={Longa, L.; Department of Statistical Physics, Marian Smoluchowski Institute of Physics, Jagiellonian University, Reymonta 4, Kraków, Poland; email: lech@alek.if.uj.edu.pl},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

To account for those properties of the environment, a standard kinetic approach in description of the system is addressed either in the framework of continuous-time random walks (CTRWs) or fractional diffusion. In this paper the power of the CTRW approach is illustrated by use of the probabilistic formalism and limit theorems that allow one to rigorously predict the limiting distributions of the paths traversed by charges and to derive effective relaxation properties of the entire system of interest. In particular, the standard CTRW scenario is generalized to a new class of coupled memory CTRWs that effectivly can lead to the well known Havriliak-Negami response. Application of the method is discussed for nonexponential electron-transfer processes controlled by dynamics of the surrounding medium. © 2005 The American Physical Society.},\nkeywords={Continuous-time random walks (CTRW);  Havriliak-Negami responses;  Hopping models;  Probabilistic formalism, Chemical relaxation;  Diffusion;  Kinetic theory;  Mathematical models;  Molecular dynamics;  Probabilistic logics, Charge transfer},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Recently published data on the time-course of chromosome aberrations in V79 first-cycle metaphases after exposure to 10.4 MeV u-1 Ar ions (LET = 1226 keV μ-1) were supplemented and reanalysed. A statistical analysis of the distribution of aberrations among cells was performed. Furthermore., cells were grouped into subpopulations carrying 0, 1-2, 3-4, 5-6 and 7 or more aberrations. Then, based on the mitotic index, the flux of each subgroup through the first mitosis was determined and the average entrance time to mitosis was estimated. For comparison, the flux of aberrant V79 cells generated by X-irradiation was analysed. Analysis of the Ar ion data revealed that the flux of each subpopulation through the first mitosis is strongly affected by its aberration burden, i.e. a positive correlation between the mitotic delay and the number of aberrations carried by a cell was observed. The distribution of aberrations among cells could be well described by Neyman-type A statistics; the corresponding fit parameters also reflect the damage-dependent mitotic delay. Interestingly, comparison of the flux of Ar ion and X-ray-irradiated V79 cells through mitosis revealed (1) that a direct correlation exists between the number of aberrations carried by a cell and its average entrance time to mitosis, and (2) that this effect is independent of the linear energy transfer. The role of these observations for radiation cytogenetics is discussed. © 2005 Taylor &amp; Francis Group Ltd.},\nauthor_keywords={Aberration yield;  Compound Poisson distribution;  High LET radiation;  Mitotic delay;  Time-course of aberrations},\nkeywords={argon, animal cell;  article;  cell strain V 79;  cell subpopulation;  cell transport;  chromosome aberration;  chromosome damage;  controlled study;  correlation coefficient;  cytogenetics;  linear energy transfer;  metaphase;  mitosis;  mitosis index;  nonhuman;  Poisson distribution;  priority journal;  statistical analysis;  X irradiation, Animals;  Argon;  Cell Proliferation;  Cells, Cultured;  Chromosome Aberrations;  Chromosome Breakage;  Cricetinae;  Mitosis;  Radiation Injuries},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The effectiveness of local (e.g. ring vaccination or culling) vs global (e.g. random vaccination) control measures is evaluated, with the aim of minimising the total cost of an epidemic. The costs include direct costs of treating infected individuals as well as costs of treatment. We first consider a random (global) vaccination strategy designed to stop any potential outbreak. We show that if the costs of the preventive vaccination are ignored, the optimal strategy is to vaccinate the whole population, although most of the resources are wasted on preventing a small number of cases. If the vaccination costs are included, or if a local strategy (within a certain neighbourhood of a symptomatic individual) is chosen, there is an optimum number of treated individuals. Inclusion of non-local contacts ('small-worlds' or scale-free networks) increases the levels of preventive (random) vaccination and radius of local treatment necessary for stopping the outbreak at a minimal cost. The number of initial foci also influences our choice of optimal strategy. The size of epidemics and the number of treated individuals increase for outbreaks that are initiated from a larger number of initial foci, but the optimal radius of local control actually decreases. The results are important for designing control strategies based on cost effectiveness.},\nkeywords={Cost effectiveness;  Diseases;  Epidemiology;  Optimization;  Social aspects;  Vaccines, Control strategies;  Scale-free networks;  Vaccination strategies, Disease control},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

The most appropriate theoretical tools to study chirality-induced structures are statistical field theory of correlation functions and computer simulations. The correlations are calculated for the order parameter fields that enter phenomenological description of a given chiral phase, like two-point correlations for cholesterics as constructed out of the alignment tensor field. A quantity that could subsequently be derived from such correlations and used to measure chirality is, for example, the optical activity tensor or, as for bent-core systems, the traceless and symmetric third-rank tensor. In this paper we explicitly show a relation between chirality and two-point correlations of the alignment tensor field. The correlations are determined from Monte-Carlo simulations for a model isotropic liquid of chiral Gay-Berne fluid. The calculated molecular quantities are consistent with recent predictions of statistical field theory.},\nauthor_keywords={Alignment tensor;  Chiral liquid crystals;  Computer simulations;  Correlation functions;  Measure of chirality},\nkeywords={Alignment;  Computer simulation;  Correlation theory;  Light scattering;  Liquid crystals;  Mathematical models;  Tensors, Alignment tensor;  Chiral liquid crystals;  Correlation function;  Measure of chirality, Molecular structure},\ncorrespondence_address1={Longa, L.; Marian Smoluchowski Inst. of Physics, Department of Statistical Physics, Jagellonian University, Reymonta 4, Krakow, Poland},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n\n

The kinetics of such a reaction is represented by an enzymatic-like Michaelis-Menten two step process. Effective free-energy surface for the process is further parameterised by the fluctuating energy barrier between the states of high and low concentration of cancerous cells. By analysing the far from equilibrium escape problem across the fluctuating potential barrier, we determine conditions of the most efficient decay kinetics of the cancer cell-population in the presence of dichotomously fluctuating concentration of cytotoxic cells. © 2004 Elsevier B.V.

We have analyzed the phenomenon with the simplest possible phenomenological models by assuming 2×2 discrete states, i.e. two normal open/closed states with two different states of "gate tension." Rates of transitions between the two branches of the hysteresis curve have been modeled with single-barrier kinetics by introducing a real-valued "reaction coordinate" parameterizing the protein's conformational change. When described in terms of the effective potential with cyclic variations of the control parameter (an activating voltage), this model exhibits typical "resonant effects": synchronization, resonant activation and stochastic resonance. Occurrence of the phenomena is investigated by running the stochastic dynamics of the model and analyzing statistical properties of gating trajectories.},\nauthor_keywords={Channel gating;  Hysteresis;  Power spectrum;  Resonant activation;  Signal to noise ratio;  Spectral amplification;  Stochastic resonance;  Synchronization},\nkeywords={Channel gating;  Power spectrum;  Resonant activation;  Spectral amplification;  Stochastic resonance, Biological membranes;  Correlation methods;  Hysteresis;  Information technology;  Information theory;  Magnetization;  Parameter estimation;  Proteins;  Signal processing;  Statistical methods;  Stochastic programming;  Synchronization, Biotechnology},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

In consequence, the distribution of PCC chromosomes plus excess fragments among cells has followed Poisson statistics after X-ray irradiation while the overdispersion of the frequencies has been observed after C-irradiation indicating that a single particle traversal through a cell nucleus can produce multiple chromatin lesions.},\nauthor_keywords={Chromatin fragmentation;  High LET C ions;  PCC technique},\nkeywords={carbon;  heavy ion, animal cell;  cell line;  cell nucleus;  cell regeneration;  Chinese hamster;  chromatin;  chromatin assembly and disassembly;  chromosome;  conference paper;  ionizing radiation;  irradiation;  linear energy transfer;  nonhuman;  Poisson distribution;  premature chromosome condensation;  priority journal;  radiation;  radiation dose;  X irradiation;  animal;  article;  CHO cell;  chromosome aberration;  DNA repair;  hamster, Animals;  Carbon;  CHO Cells;  Chromosome Aberrations;  Cricetinae;  DNA Repair;  Heavy Ions;  Linear Energy Transfer;  Poisson Distribution},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

We have analyzed the phenomenon with the simplest possible phenomenological models by assuming 2×2 discrete states, i.e. two normal open/closed states with two different states of "gate tension." Rates of transitions between the two branches of the hysteresis curve have been modeled with single-barrier kinetics by introducing a real-valued "reaction coordinate" parameterizing the protein's conformational change. When described in terms of the effective potential with cyclic variations of the control parameter (an activating voltage), this model exhibits typical "resonant effects": synchronization, resonant activation and stochastic resonance. Occurrence of the phenomena is investigated by running the stochastic dynamics of the model and analyzing statistical properties of gating trajectories.},\nauthor_keywords={Channel gating;  Hysteresis;  Power spectrum;  Resonant activation;  Signal to noise ratio;  Spectral amplification;  Stochastic resonance;  Synchronization},\nkeywords={Channel gating;  Power spectrum;  Resonant activation;  Spectral amplification;  Stochastic resonance, Biological membranes;  Correlation methods;  Hysteresis;  Information technology;  Information theory;  Magnetization;  Parameter estimation;  Proteins;  Signal processing;  Statistical methods;  Stochastic programming;  Synchronization, Biotechnology},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

We consider a case when individuals can be infectious before showing symptoms and thus before detection. For small to moderately severe incidence of infection with a small number of nonlocal links, it is possible to control disease spread by using purely local methods applied in a neighborhood centered around a detected infectious individual. There exists an optimal radius for such a control neighborhood leading to the lowest severity of the epidemic in terms of economic costs associated with disease and treatment. The efficiency of a local control strategy is very sensitive to the choice of the radius. Below the optimal radius, the local strategy is unsuccessful; the disease spreads throughout the system, necessitating treatment of the whole population. At the other extreme, a strategy involving a neighborhood that is too large controls the disease but is wasteful of resources. It is not possible to stop an epidemic on scale-free networks by preventive actions, unless a large proportion of the population is treated. © 2004 The American Physical Society.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Among diverse types of melanins, the human melanins, eumelanins, are brown or black nitrogen-containing pigments, mostly known for their photoprotective properties in human skin. We have undertaken theoretical studies aimed to understand absorption spectra of eumelanins and their chemical precursors. The structure of the biopigment is poorly defined, although it is believed to be composed of cross-linked heteropolymers based on indolequinones. As a basic model of the eumelanin structure, we have chosen pentamers containing hydroquinones (HQ) and/or 5,6-indolequinones (IQ) and/or semiquinones (SQ) often listed as structural melanin monomers. The eumelanin oligomers have been constructed as random compositions of basic monomers and optimized for the energy of bonding. Absorption spectra of model assemblies have been calculated within the semiempirical intermediate neglect of differential overlap (INDO) approximation. Model spectrum of eumelanin has been further obtained by sum of independent spectra of singular polymers. By comparison with experimental data it is shown that the INDO/CI method manages to reproduce well characteristic properties of experimental spectrum of synthetic eumelanins.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Full advantage is taken of the symmetry of the nematic state and of the molecules. The explicit analysis and classification of the terms involving spherical harmonics with indices not exceeding 4 is given and illustrated using computer simulations for the nematic phase of a Gay-Berne mesogen. The theory is contrasted with the commonly used approach employing invariants that describe orientational correlations in molecular fluids. The role of the new representation in obtaining a correct understanding of a variety of observables, like the elastic constants, is demonstrated. In particular, the long-standing puzzle concerning the splay-bend degeneracy is resolved.},\ncorrespondence_address1={Longa, L.; Inst. fur Theor. und Angew.

In extended time-course studies an drastic increase in the number of aberrations with sampling time has been observed after particle irradiation, while after the exposure to sparsely ionizing radiation a less pronounced effect has been found. This difference in the time-course of chromosomal damage is particularly important for the determination of accurate RBE values. As will be discussed, meaningful RBE values for particles can only be obtained, if cells are analysed at multiple sampling times and the complete time-course of aberrations is considered. Otherwise, particle-induced damage will be over- or underestimated. Moreover, depending on the cell system chosen for the analysis, factors like the loss of damaged cells due to apoptosis or a permanent cell cycle arrest complicate the determination of accurate RBE values based on chromosome data.},\nauthor_keywords={High LET radiation;  Radiation risk assessment;  RBE;  Time-course of chromosome aberrations},\nkeywords={animal cell;  apoptosis;  cell cycle;  CHO cell;  chromosome aberration;  chromosome damage;  conference paper;  controlled study;  ionizing radiation;  linear energy transfer;  metaphase;  mitosis;  nonhuman;  radiation exposure;  radiation hazard, Animals;  Apoptosis;  Cell Cycle;  Cell Line;  Chromosome Aberrations;  Cricetinae;  Cricetulus;  Dose-Response Relationship, Radiation;  Heavy Ions;  Humans;  Linear Energy Transfer;  Metaphase;  Mitosis;  Relative Biological Effectiveness;  Skin;  Time Factors;  X-Rays, Animalia},\ndocument_type={Conference Paper},\nsource={Scopus},\n}\n\n

At high temperatures, this frustrated Gay-Berne mesogen exhibits an ideally oriented nematic phase, which is the reference state of the system. In the limit of vanishing dipole moment nematic, smectic-A and smectic B phases are stable. Interestingly, by changing the magnitude and location of the molecular dipole in the nematic reference state we found dipole-induced smectic A, smectic B and tetragonal crystal phases, in addition to crystalline structures with smectic Ad and A2-like dipolar organization. Various singlet, pair and triplet distribution functions were evaluated to elucidate short and long range organization in these phases. In particular, the importance of triplet correlations for a proper understanding of the structures and their local, dipolar organization is demonstrated.},\ncorrespondence_address1={Longa, L.; Institute of Physics, Jagellonian University, Reymonta 4, 30-059 Kraków, Poland},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Materials and methods: Cells were exposed in G1 to 10.4 MeV/u Ar ions (LET = 1226 keV/μm) and chromosomal damage was measured at 2 h sampling intervals between 10 h and 34 h after irradiation. To distinguish between cells in different post-irradiation cycles, the fluorescence-plus-Giemsa technique was applied. Results: For first- and second-generation cells, the number of aberrant metaphases and aberrations per metaphase were found to increase markedly with sampling time, demonstrating that cell cycle progression was delayed according to the number of lesions carried by the cell. To account for the time-dependent expression of chromosomal damage a mathematical approach was used based on the integrated flux of aberrant cells entering mitosis. Moreover, the analysis of Ar ion-induced chromosome lesions confirmed that high-LET radiation results in specific changes in the spectrum of aberration types. In particular, an increased rate of chromatid-type aberrations as well as a high frequency of chromosomal breaks was found, although the cells were exposed in G1. Conclusions: Due to the fact that cells collected at one sampling time are not representative of the entire population, the complete time-course of chromosomal damage has to be taken into account for the determination of a meaningful RBE value. Otherwise, the analysis of chromosomal damage can result in a pronounced over- or underestimation of the RBE depending on the subpopulation of cells entering mitosis at that particular sampling time.},\nkeywords={argon, animal cell;  article;  cell cycle;  cell cycle G1 phase;  cell strain V 79;  Chinese hamster;  chromatid;  chromosome aberration;  controlled study;  fluorescence;  Giemsa stain;  ionizing radiation;  mathematical analysis;  metaphase;  mitosis;  nonhuman;  priority journal;  radiation dose;  sampling, Animals;  Cell Line;  Chromosome Aberrations;  Chromosomes;  Cricetinae;  Cricetulus, Animalia;  Cricetinae;  Cricetulus griseus},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

It is based on a functional Taylor expansion of the free energy of a distorted biaxial nematic with respect to the one-particle distribution function. Detailed microscopic expressions for the biaxial elastic constants of bulk and surface deformations are derived by expanding further the distribution functions into symmetry-adapted Wigner matrices. The final expressions depend on generalized orientational order parameters characterizing the biaxial nematic and on expansion coefficients of the direct pair correlation function. The case where the expansions are truncated at the lowest nontrivial order with respect to the momentum index of the Wigner matrices is analyzed in detail. It gives only six distinct, nonzero bulk elastic constants. The mixed elastic constants, which measure distortions of more than one director, vanish within this approximation. As in the uniaxial case, a splay-bend degeneracy for all directors is apparent. The theory is next applied to the biaxial nematic phase recently studied by Biscarini et al. [Phys. Rev. Lett. 75, 1803 (1995)] providing numerical estimates of biaxial elastic constants for the case of thermodynamically stable biaxial ordering. It is shown that the values of the elastic constants connected with secondary directors are much lower than those associated with the primary one. © 1998 American Institute of Physics.},\ncorrespondence_address1={Longa, L.; Instytut Fizyki, Uniwersytet Jagielloński, Reymonta 4, 30-059 Kraków, Poland},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Stark and H.-R. Trebin, Phys. Rev. A 44, 2752 (1991)]. In the present approach not only the wave vectors of the cubic structures are distorted, but also the scalar amplitudes of the order parameter. By considering a full spectrum of the distortions exact formulas (within the Landau-deGennes approach) for the components of the electrostriction tensor are derived. Detailed results of the numerical calculations are compared with those obtained from the earlier model and with experimental data. It is shown that the electrostriction coefficients are strongly affected by the deformations of the amplitudes. Quantitatively, for low temperatures (or high chiralities) the contribution due to the deformed amplitudes exceeds that from the distortions of the wave vectors. The results are in good agreement with experimental data except for the region where the anomalous electrostriction of the blue phase I is observed. This proves that a correct description of the anomalous electrostriction is beyond the standard Landau-deGennes theory of the blue phases as suggested in our recent publication [L. Longa, M.

On the basis of these simulations for the nematic phase, a subset of the spherical harmonic expansion coefficients of the direct pair correlation function (DPCF) were determined from the pair distribution function (PDF) by solving the Ornstein-Zernike (OZ) equation. This was achieved by generalizing the Wiener-Hopf factorization scheme for the numerical solution of the OZ equation. Only the expansion coefficients gl1,l2,l(r) (lα≤4) of the PDF in the laboratory frame were used when solving the OZ equation; this means that the DPCF so obtained is equivalent to that for a nematic in which the director is randomly distributed. From the DPCF, the scaled Oseen-Zöcher-Frank elastic constants K11*, K22*, and K33*, as well as the surface constant K13*, have been calculated from the subset of expansion coefficients. Generally, we find that K33*&lt;K11*,&lt;K22*, in agreement with what is expected and found for discotic nematics. These results are quantitatively but not qualitatively different from those calculated with the help of analytical approximations for the the same spherical harmonic expansion coefficients of the direct pair correlation function. For example, the values of the bulk elastic constants determined via the OZ equation are about three times larger than the bulk elasticity obtained with the low density approximation. © 1997 American Institute of Physics.},\ncorrespondence_address1={Stelzer, J.; Instytut Fizyki, Uniwersytet Jagielloński, Reymonta 4, Kraków, Poland},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

This phenomenon is termed anomalous electrostriction and together with topology of phase diagrams of the blue phases awaits elucidation. Standard theory of blue phases is not able to explain these observations. Following the experiments of Pierański et al. we generalized the standard theory by incorporating a nonlinear dielectric susceptibility tensor (NDS). It is shown that the distortion of the cubic blue phase I in the presence of the NDS may display the anomalous electrostriction, in accordance with experiment. These results seem to indicate that nonlinear susceptibility tensor is a relevant order parameter for the blue phases.},\ncorrespondence_address1={Longa, L.; Jagiellonian University, Institute of Physics, Reymonta 4, Kraków, Poland},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Standard theories of blue phases based on an expansion of the free energy in powers of the alignment tensor Q(r) are not able to explain this anomaly. Cubic blue phases possess a strong nonlinear dielectric susceptibility [Formula Presented], as shown by experiments of Pierański, Cladis, Garel, and Barbet-Massin [J. Phys. (Paris) 47, 139 (1986)]. Hence the corresponding order parameter, which we denote “bond orientational tensor,” must be included in a theoretical description of the blue phases. Indeed, it has been proposed that the blue phase III is a structure of pure bond orientational order. Incorporating the bond orientational tensor into the free energy expansion, we have calculated the distortion of the [Formula Presented](I[Formula Presented]32) and [Formula Presented](P[Formula Presented]32) blue phase lattices by a weak electric field within the model of rigid helices. The resulting fourth-order electrostriction tensor is expressed in terms of the order parameters characterizing the [Formula Presented] and the [Formula Presented] ground states of the undistorted system. The relations generalize studies of Stark and Trebin [Phys. Rev. A 44, 2752 (1991)]. It is found that there exists a range for the coupling strength between Q(r) and [Formula Presented] where anomalous electrostriction is predicted for blue phase I, in accordance with experiment. Thus bond orientational order seems to provide a link between two unsolved problems: that of the anomalous electrostriction of the blue phase I and that of the structure of the blue phase III. © 1996 The American Physical Society.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In some preparations, the steady-state probabilities of observing these levels do not follow a binomial distribution. This behavior has been reported in sodium channels, potassium channels, acetylcholine receptor channels and gap junction channels. A non-binomial distribution suggests interaction of the channels or the presence of channels with different open probabilities. However, the current trace sometimes exhibits single transitions spanning several levels. Since the probability of simultaneous transitions of independent channels is infinitesimally small, such observations strongly suggest a cooperative gating behavior. We present a Markov model to describe the cooperative gating of channels using only the all-points current amplitude histograms for the probability of observing the various conductance levels. We investigate the steady-state (or equilibrium) properties of a system of N channels and provide a scheme to express all the probabilities in terms of just two parameters. The main feature of our model is that lateral interaction of channels gives rise to cooperative gating. Another useful feature is the introduction of the language of graph theory which can potentially provide a different avenue to study ion channel kinetics. We write down explicit expressions for systems of two, three and four channels and provide a procedure to describe the system of N channels. © 1996 Society for Mathematical Biology.},\nkeywords={cholinergic receptor;  ion channel, animal;  article;  biological model;  cell junction;  cell membrane;  channel gating;  mathematics;  patch clamp;  physiology;  probability, Animals;  Cell Membrane;  Gap Junctions;  Ion Channel Gating;  Ion Channels;  Markov Chains;  Mathematics;  Models, Biological;  Patch-Clamp Techniques;  Receptors, Cholinergic, Animalia},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

We noticed that this effect was less pronounced in patients with hypercholesterolemia. The aim of the study was to prove this observation. The effects of aspirin on thrombin generation were evaluated in (1) 46 healthy volunteers, 2 hours after ingestion of a single, 500-mg dose and (2) 28 survivors of myocardial infarction who took 300 mg aspirin/d for 2 weeks. In both populations, two well-matched subgroups were distinguished, using a serum cholesterol level of 6.2 mmol/L (240 mg/dL) and an LDL cholesterol level of 4.0 mmol/L (155 mg/dL) as borderline. Thrombin generation was monitored ex vivo in blood emerging from a skin microvasculature injury and additionally, in a single-dose study in vitro in recalcified plasma. Aspirin depressed thrombin generation in the group of subjects with serum cholesterol <6.2 mmol/L and LDL cholesterol <4.0 mmol/L but not in the group with high blood cholesterol levels. Inhibitory effects of aspirin were more pronounced after the 2-week treatment than after a single dose. There was a significant correlation between total serum cholesterol or LDL cholesterol and total amount of thrombin generated after aspirin treatment. In subjects with high blood cholesterol levels, thrombin generation was not affected by aspirin. Blunting of aspirin action in hypercholesterolemia might be explained by (1) alterations in platelet lipid-protein matrix that render their membrane proteins less accessible for acetylation by aspirin and (2) changes in composition and structure of plasma lipoproteins that diminish the chance of aspirin to interact with prothrombin.},\nauthor_keywords={hypercholesterolemia;  myocardial infarction;  thrombin generation},\nkeywords={acetylsalicylic acid;  cholesterol;  low density lipoprotein cholesterol;  membrane protein;  prothrombin;  thrombin, acetylation;  adult;  aged;  article;  blood clotting;  cholesterol blood level;  female;  heart infarction;  human;  human experiment;  hypercholesterolemia;  lipid bilayer;  lipoprotein blood level;  male;  priority journal;  protein analysis;  protein lipid interaction;  protein structure;  thrombocyte structure},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In deriving the elastic constants a direct correlation function approach of Poniewierski and Stecki1 in a version proposed by Lipkin et al.5 was choosen. The final formulas have been expressed in terms of the orientational order parameters and of the angular coefficients of the direct correlation function of an unoriented nematic. The latter have been determined exactly from the molecular dynamics simulations in the NVT ensemble. Results for the surface elastic constants, qualitatively different than those obtained from all previous treatments, clearly show that the surface deformations are strongly sensitive to details of the direct correlation function.

Rev. E 47, 343 (1993)]. On the basis of these simulations the absolute values of the Oseen-Zöcher- Frank elastic constants K11, K22, and K33 as well as the surface constants K13 and K24 have been calculated ab initio within the framework of the direct correlation function approach of Lipkin et al. [J. Chem. Phys. 82, 472 (1985)]. The angular coefficients of the direct pair correlation function, which enter the final equations, have been determined from the computer simulation data for the pair correlation function of the nematic by combining the Ornstein-Zernike relation and the Wiener-Hopf factorization scheme. The unoriented nematic approximation has been assumed when constructing the reference state of Lipkin et al. By an extensive study of the model over a wide range of temperatures, densities and pressures, very detailed information is provided on the elastic behavior of the Gay-Berne nematic. Interestingly, it is found that the results for the surface elastic constants are qualitatively different from those obtained with the help of analytical approximations for the isotropic direct pair correlation function. For example, the values of the surface elastic constants are partly negative and an order of magnitude smaller than the bulk elasticity. The negative values of the surface constant K13 indicate on the possibility of surface instabilities of the director pattern in a thin, free standing or weakly anchored Gay-Berne nematic liquid crystal. © 1995 American Institute of Physics.},\ncorrespondence_address1={Stelzer, J.; Institut für Theoretische und Angewandte Physik, Universität Stuttgart, Pfaffenwaldring 57, D-70550 Stuttgart, Germany},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

In particular, the cholesteric phase, the cubic blue phases, and the phases characterized by an icosahedral space group symmetry are analyzed in detail. Also, a general question concerning the applicability of the mean-field approximation in describing the chiral phases is addressed. By an extensive study of the model over a wide range of the parameters, a class of phenomena, not present in the original de GennesGinzburgLandau model, has been found. These include (a) reentrant phase transitions between the cholesteric and the cubic blue phases and (b) the existence of distinct phases of the same symmetry but of different biaxialities. The phase biaxiality serves here as an extra scalar order parameter. Furthermore, it has been shown that, due to the presence of competing bulk terms in the free energy, the stable phases may acquire a large degree of biaxiality, also in liquid crystalline materials composed of effectively uniaxial molecules. A study of icosahedral space group symmetries provides a partial answer to the question of whether or not an icosahedral quasicrystalline state can be stabilized in liquid crystals. Although, in general, the stability of icosahedral structures could be enhanced by the extra terms in the free energy, no absolutely stable icosahedral phase has been found. © 1994 The American Physical Society.},\ncorrespondence_address1={Longa, L.; International Centre for Theoretical Physics, P.

Recent molecular dynamics (MD) studies of reaction centers (RC) show that the dynamical response of the proteic environment has noticeable nonlinear behavior, and the observed slow decay of the time correlation functions is suggestive of glassy dynamics in the system. In this context, we consider two possible models for the RC relaxation times. The first model of a "static disorder" discusses relaxation dynamics in the presence of a "rough" free energy potential. A rough potential has a smooth background on which randomly fluctuating local perturbations are superimposed. Distribution of the perturbations determines the relaxation dynamics and may be responsible for the dynamical, temperature-dependent phase change in the medium. In particular, the mean sojourn time in such a free energy potential well is no longer exponentially distributed, and this effect may explain the complex decay dynamics of the primary donor in RCs. A similar behavior can be found in a complementary model of a "dynamic disorder" where spontaneous conformational isomerization of chromophores causes the transition from one configurational state to another and back. The importance of such a transition, induced by a polar group isomerization in the neighboring amino acid side chains of bacteriochlorophylls, has been suggested in the MD studies of the time-variations of the electrostatic energy at the chromophores in RCs. With the assumption that the time the system spends in a particular conformation state is Poisson distributed, the decay time is evaluated by a stochastic analysis of the isomerization process and compared with kinetics predicted by other models of the primary ET in RCs. © 1994 American Chemical Society.},\nkeywords={Electron transfer;  Heterogeneity;  Molecular dynamics;  Reaction centers, Chemical relaxation;  Electron energy levels;  Order disorder transitions;  Phase transitions, Photosynthesis},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

However, the amplitudes of these revivals are very small. For long times, individual revivals partially overlap to form fractional revivals, and for even longer times superrevivals (revivals of the revivals) appear.

These superstructures generalize phenomena described previously (fractional revivals). They result from beating of not-nearest-neighbor eigenstates of the system, and we show which beats lead to particular types of revivals. In addition, the cavity field develops macroscopically distinguishable states (optical Schrödinger-cat states). These stages emerge when the fractional revivals with a frequency of 2/tR, 3tR, and 4/tR, where tR is the single-revival period, appear for the second, fourth, sixth, etc., time in the superstructure pattern. © 1993 The American Physical Society.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

This observation seemed to deserve verification since atopic patients whose production of IgE was excessive had been reported to have depressed haemostatic platelet function and impaired thrombinogenesis. Methods: We measured levels of serum IgE in 386 patients with AMI at the time of admission to the coronary care unit. Patients were divided into two groups, depending on the presence (n = 55) or absence (n = 331) of sudden cardiac arrest. The two groups did not differ with respect to age, sex, or risk factors for coronary artery disease. Results: The mean level of serum IgE was significantly higher in the group without sudden cardiac arrest than in the group with this complication. In a separate study we found that high serum IgE levels were associated with delayed thrombin generation in the clotting blood of survivors of myocardial infarction. Conclusion: Early determination of serum IgE levels might help to detect patients at risk of sudden cardiac arrest during myocardial infarction. Patients with high serum IgE levels might be protected against sudden cardiac death through the depression of clot formation because of the late appearance of thrombin in their coronary arteries.},\nauthor_keywords={atopy;  myocardial infarction;  serum IgE;  sudden cardiac death;  thrombin generation},\nkeywords={immunoglobulin E;  thrombin, acute heart infarction;  adult;  aged;  article;  atopy;  blood clotting;  controlled study;  coronary care unit;  female;  heart arrest;  high risk patient;  human;  immune response;  immunoglobulin blood level;  major clinical study;  male;  priority journal;  sudden death;  thrombin time},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

We studied the effects of four antiplatelet drugs on thrombin formation in healthy volunteers. Thrombin generation was monitored both in vitro-in recalcified plasma-and ex vivo-in blood emerging from a standardized skin microvasculature injury, which also served to determine bleeding time. A mathematical model has been developed to describe the latter reaction. It is based on estimation of the rate of increase in fibrinopeptide A (FPA), a specific marker of thrombin activity, in blood emerging from skin incisions. Two hours after the ingestion of 500 mg of aspirin, thrombin formation became significantly impaired both in vitro and ex vivo. In contrast, 2 hours after the oral administration of placebo, indomethacin 50 mg, or OKY-046 (a thromboxane synthase inhibitor) 400 mg, thrombinogenesis remained unaltered. Ticlopidine, studied either 3 hours after 500 mg oral administration, or after 5 days of intake at a daily dose of 500 mg, had no effect on thrombin generation. Thus, aspirin, contrary to other antiplatelet drugs, depresses thrombin formation in clotting blood, a phenomenon that might be of clinical relevance. It is suggested that aspirin exerts this effect by acetylating prothrombin and/or macromolecules of platelet membrane.},\nkeywords={acetylsalicylic acid;  antithrombocytic agent;  fibrinopeptide a;  indometacin;  ozagrel;  ticlopidine, article;  bleeding;  bleeding time;  blood clotting;  controlled study;  drug effect;  human;  mathematical model;  priority journal;  protein secretion;  thrombin time, Adult;  Aspirin;  Blood Coagulation;  Female;  Fibrinopeptide A;  Human;  In Vitro;  Indomethacin;  Kinetics;  Male;  Mathematics;  Methacrylates;  Middle Age;  Models, Biological;  Platelet Aggregation Inhibitors;  Skin;  Thrombin;  Thromboxane-A Synthase;  Ticlopidine},\ndocument_type={Article},\nsource={Scopus},\n}\n\n%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\n%\n% Bartłomiej Dybiec\n%\n%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\n

Full advantage is taken of the symmetry of the order parameters by systematic use of the method of integrity bases, which allows us to establish an expansion of the most general SO(3)-invariant free-energy density to arbitrary powers in the components Q and P. A coordinate-independent parametrization of the invariants is introduced that yields a classification of local polar structures and some predictions about possible topologies of phase diagrams without the necessity of performing numerical calculations. As one prominent result, the theory predicts a polar, chiral biaxial state that exists due to a piezoelectric coupling of a chiral biaxial tensor field and the polarization field and which disappears if tensor is uniaxial. We then provide a general theory of flexopolarization in biaxial systems. A general biaxial system is described by 12 fundamental flexopolarization modes. Special cases, obtained by imposing symmetry restrictions to the tensor field Q, reduce the number of modes. Finally, the theory is applied to chiral phases. Simple polar chiral structures including cholesteric and smectic-C* liquid crystals are analyzed. In particular, it is shown that if the smectic-C* phase is stabilized due to the piezoelectric coupling between Q, P, and a density wave, then it must be described as a biaxial uniform spiral with at least two nonvanishing commensurate harmonics. The minimization of the quadratic part of the Landaude Gennes energy supplemented by (flexo)polarization terms may give rise to incommensurate two- or three-dimensional polar structures that can be stabilized by cubic terms. © 1990 The American Physical Society.},\ncorrespondence_address1={Longa, L.; Institute of Physics, Jagellonian University, Reymonta 4, Kraków, Poland},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Experimental redox and optical results for puckered porphyrins have also established that such conformational variations can affect the highest occupied and lowest unoccupied molecular orbitals of the chromophores and thereby modulate their light-absorption properties. The concept is applied to the bacteriochlorophyll a (BChl) antenna protein complex from Prosthecochloris aestuarii, whose structure has been solved by X-ray diffraction (J. Mol. Biol. 1986, 188, 443). INDO/s calculations, based on the crystallographic data for the seven individual BChls that comprise the antenna complex, yield absorption maxima that reflect the observed conformational variations and clearly establish that skeletal differences can influence the optical properties of the chromophores.

In particular, the tricritical points are found for a large class of orderparameter theories of nematic-smectic A (-A1, -AD) and -A2 (NA) phase transitions. These include generalizations to antiferroelectric smectic-A phases of McMillan and Meyer-Lubensky mean-field theories and the Ramakrishnan-Youssouff(RY) density-functional approach. The use of these different approaches allows study of influence of various couplings between nematic (orientational) and smectic (translational) degrees of freedom and polarization field, P1(cos θ), on various NA and AA phase transitions. From the results, it is of interest that the coupling between orientational degrees of freedom (P4(cos θ) and density waves can destabilize the smectic-A phase at low temperatures-pointing to the existence of a nematic-smectic-A-reentrant-nematic phase transition. A possible relation of this result to Ad, C2, Cd and [ctilde] phases is discussed. Some relations between Fourier components of correlation functions and order parameters at tricritical points are derived from the RY density-functional theory. Despite some limitations, the theory presented here seems to provide the simplest approach to study topologies of phase diagrams in molecular theories. © 1989 Taylor and Francis Group, LLC.},\ncorrespondence_address1={Longa, L.; Universität Paderborn, Physikalische Chemie, Postfach 1621, Paderborn, 4790, Germany},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

By this method all linearly independent elastic invariants and surface terms are constructed for nematics and cholesterics up to fourth order terms. In particular it is shown that up to fourth order in the tensor order parameter there are nineteen bulk elastic constants and four surface terms in the free energy of a general, biaxial nematic. In addition, the stability of this expansion is studied in detail. Some special cases of the elastic free energy of liquid crystals, already discussed in the literature, are reexamined and discrepancies with our results are emphasized. Finally, a thermo-dynamically correct way of establishing contact between the generalized de Gennes elastic free energy and other theories, like those of Oseen-Frank or Meyer, is proposed by applying fluctuation theory. Thus, the degeneracy of splay and bend elastic constants is removed even when these are calculated from the standard de Gennes free energy. Restrictions on higher order elastic constants are also obtained by comparing mean field relations and stability conditions with available experimental data. © 1987 Taylor & Francis Group, LLC.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

The theory is applied to some molecular models of the nematic-smectic A (NA) phase transition of liquid crystals. It is shown exactly that for a large class of molecular theories the NA tricritical temperature depends only on the couplings between the two lowest order translational order parameters and the orientational degrees of freedom. The relative importance of these couplings on tricritical behavior is studied in detail in the mean-field approximation. Numerical analysis is carried out for various molecular models of the smectic A phase including the McMillan model and its generalizations. It is shown that for an experimentally relevant class of models, the presence of second and higher order harmonics does not influence the tricritical temperature in an essential way, which means that the coupling between orientational and translational degrees of freedom is likely to be dominant in determining the character of the NA phase transition. Another interesting aspect of orientational-translational coupling is the possibility of the existence of the nematic-smectic A-reentrant nematic phase transition. © 1986 American Institute of Physics.},\ncorrespondence_address1={Longa, L.; Institut für Theoretische und Angewandte Physik, Universität Stuttgart, Pfaffenwaldring 57/VI, 7000 Stuttgart 80, Germany},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

First the experimental evidence is reviewed, which leads to a division in strong complexing (electron-donor- acceptor complex as indicated by a charge-transfer band) and weak complexing, where only indirect evidence is available. Within the mean field approximation a theoretical model is given in which the influence of complex formation on the nematic-smectic A transition temperature is investigated for ideal orientational order. The ISP mechanism is attributed to the dispersive interactions between the complexes. However, in principle in a two-component mixture without complexing also ISP can be obtained due to interactions involving permanent dipoles. From fits to experimental phase diagrams and from estimates of parameters it follows that the first mechanism is more likely. Three nonstandard groups of phase diagrams with characteristic maxima or minima are predicted. The location of the extrema is calculated as a function of complex concentration and effective intermolecular interactions. The model correctly describes presently existing, very rich, experimental data. © 1986 American Institute of Physics.},\ncorrespondence_address1={De Jeu, W.H.; Solid State Physics Laboratory, Melkweg 1, 9718 EP Groningen, Netherlands},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

Order parameters are introduced that retain information on the head-tail asymmetry of the constituent molecules. Minimum ingredients are given for a mean-field model potential, with the additional use of the approximation of ideal orientational order. With reasonable estimates for the various types of interaction (dispersion, dipole induced-dipole, and dipole-dipole) no ferroelectric smectic phase is found. Polarized layers can couple, however, to double layers, which leads to the antiferroelectric smectic-A2 phase. In addition, an antiferroelectric smectic-A1 phase is found, which has a single-layer periodicity. In that case there is a bilayer structure as in smectic-A2, which is now not long ranged. For high orientational order the antiferroelectricity of these phases is shown to be the best compromise between the repulsion of the permanent dipole moments and the attractive induced interactions. The relative stability of the various phases is considered in detail. The predictions agree well with present experimental observations. © 1983 The American Physical Society.},\ncorrespondence_address1={Longa, L.; Solid State Physics Laboratory, University of Groningen, Melkweg 1, 9718-EP Groningen, Netherlands},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

It is shown that the induced forces between dimers, monomers, and between monomers and dimers, respectively, under suitable conditions of temperature and density lead to a smectic layer structure with a period equal to the length of the dimer. However, with decreasing temperature or increasing density, repulsive steric forces, due to the unfavorable packing of the dimers in the smectic planes, may take over and thus favor the nematic phase again. In agreement with experiment the best conditions to get a reentrant nematic phase are predicted for the ratio of the length of the dimer to that of the monomer between 1.3 and 1.4. The predictions of the model are in good agreement with currently available experimental data. In principle, the model applies also to discotic liquid crystals. © 1982 The American Physical Society.},\ncorrespondence_address1={Longa, L.; Solid State Physics Laboratory, University of Groningen, Melkweg 1, 9718 EP Groningen, Netherlands},\ndocument_type={Article},\nsource={Scopus},\n}\n\n

These structures facilitate transitions between homogeneous steady states. Moreover, the dependence of the transition time on diffusion is not monotonous, but shows a significant minimum. © 1982.},\ndocument_type={Article},\nsource={Scopus},\n}\n\n%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\n%\n% Paweł Góra\n%\n%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\n\n

The phase transition temperatures are lower than that of a ferromagnetic Ising model and increase with decreasing frustration.

Particles interact with each other through the infinite-range, infinitely weak attractive Kac potential, and through a nearest-neighbor short-range potential. The latter depends also on the internal states of the interacting particles. Exact results for thermodynamic properties and for some correlation functions are obtained. It is found that the considered system exhibits several first-order transitions between phases with different "rotational structure," i.e., with different ordering with respect to the internal degrees of freedom. The calculated equation of state seems to suggest that in the solutions of liquid-crystalline substances in neutral solvents there may exist regions in which the coefficient of thermal expansion is negative-an effect similar to that well known in liquid water. © 1979 Plenum Publishing Corporation.},\nauthor_keywords={hard-core softening;  internal degrees of freedom;  liquid crystals;  One-dimensional systems;  phase transitions;  rotational order},\ncorrespondence_address1={Fuliński, A.; Institute of Physics, Jagellonian University, Kraków, Poland},\ndocument_type={Article},\nsource={Scopus},\n}\n\n%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\n%\n% Ewa Gudowska-Nowak\n%\n%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\n
