A new method based on the local analysis of the orientational order has been presented for analysis of the phase behavior of the Stockmayer fluid. A quantity has been introduced to quantitatively describe the ordering degree of particles at small distances. It has been used to analyze the phase diagram of the model under consideration.

Численное моделирование модели Штокмаера проводится методом Монте-Карло для частиц с достаточно большим дипольным моментом (m*<4.2). При концентрациях 0.16<p<0.31 показано наличие колончатой фазы, состоящей из параллельных цилиндрических слоёв, причём в каждом цилиндре частицы образуют кристаллическую структуру, а их дипольи сонаправлены и параллельны оси цилиндра. Направления диполей ближайших цилиндров противоположны. ...

The population annealing method is a promising approach for large-scale simulations because it is potentially scalable on any parallel architecture. We present an implementation of the algorithm on a hybrid program architecture combining CUDA and MPI. The problem is to keep all general-purpose graphics processing unit devices as busy as possible by efficiently redistributing replicas. ...

Atomistic aspects of the structural organization, dynamics, and functioning of hydrated lipid bilayers - model cell membranes - are primarily governed by the fine balance of intermolecular interactions between all constituents of these systems. Besides the hydrophobic effect, which shapes the overall skeleton of lipid membranes, very important contribution to their behavior is made by ...

We review recent advances in the analysis of the Wang–Landau algorithm, which is designed for the direct Monte Carlo estimation of the density of states (DOS). In the case of a discrete energy spectrum, we present an approach based on introducing the transition matrix in the energy space (TMES). The TMES fully describes a random ...

We observe the self-assembling of the dipolar hard sphere particles at low temperature by Monte Carlo simulation. We find different types of stable structures of dipolar particles which appear when the isotropic phase of the system becomes unstable. Specifically, we find an interesting case of parallel cylindrical domains. The value of the total dipole moment ...

The rise of sea level will enhance erosion of cliffs that will be in the reach of storm waves in the distant future. We analyse the possible consequences of erosion-driven collapse of the cliff of Cap Canaille, located approximately 20 km from Marseille, France. A resulting fall of large amount of rocks (several millions m3) ...

In the framework of circular restricted three-body problem the libration point orbits form the families of periodic and quasi-periodic solutions. In the paper, the mapping of initial conditions is utilized to describe and study the structure and properties of these families. A new numerical method for orbit generation, which is applicable both for the periodic ...

The gas-phase fragmentation reactions of Keggin-type [PW11O39MCl]5– (M = Rh, Ir) polyoxometalates (POMs) featuring chloride terminal ligands have been investigated. Different adducts of the general formulas [PW11O39MCl + 2cat]3– and [PW11O39MCl + 3cat]2– [cat = alkylammonium cations (Me4N+, Bu4N+), alkali cations (Na+, K+) or protons] were subjected to collision-induced dissociation (CID) conditions.

Entropy balance in the one-dimensional hyperbolic quasi-gasdynamic (HQGD) system of equations is analyzed. In regular flow regimes, it is shown that the behavior of entropy in the HQGD system is determined by terms involving the natural viscosity and thermal conductivity coefficients. The total entropy production differs from the Navier–Stokes equations for viscous compressible heat-conducting gases ...

Invagination of epithelial sheets is an important type of morphogenetic deformation. Primary
invagination during gastrulation in the sea urchin provides one of the simplest and best-studied examples.
The specific mechanisms of invagination remain unclear in spite of numerous observations. The problem of
plane-stress deformation of an initially circular layer exposed to a constant internal pressure is considered.
Active forces ...

Предложена модель первичного вакуума, состоящего из частиц с планковскими масштабами длины, времени жизни и массы, которые названы эфиронами. Квантовое гравитационное поле отождествляется с возбужденным состоянием эфиронного бозе-конденсата. Гравитон определяется как квазичастица волнового поля свободных эфиронов. В рамках квантово-полевого подхода дано объяснение формулы закона всемирного тяготения. ...

We consider an initial-boundary value problem for a generalized 2D time-dependent Schrödinger equation on a semi-infinite strip. For the Crank-Nicolson finite-difference scheme with approximate or discrete transparent boundary conditions (TBCs), the Strang-type splitting with respect to the potential is applied. For the resulting method, the uniform in time L2-stability is proved. Due to the ...

We construct asymptotic solutions of the Navier–Stokes equations. Such solutions describe periodic systems of localized vortices and are related to topological invariants of divergence-free vector fields on two-dimensional cylinders or tori and to the Fomenko invariants of Liouville foliations. The equations describing the evolution of a vortex system are given on a graph that is ...

In this article, we show numerically the strong finite-size effects in exponential random graphs. Particularly, for the two-star model above the critical value of the chemical potential for triplets a ground state is a star-like graph with the finite set of hubs at network density p<0.5p<0.5 or as the single cluster at p>0.5p>0.5. We find that there exists ...
