]]>Using the bilinear Markov chain approach, we study statistical properties of natural random symbolic sequences with complex correlation properties. In the limit of weak correlations, we present analytically the entropy of sequence by means of correlation functions of the second and third orders. We ...

]]>We develop a technique for calculating three-dimensional classical partition functions using projected entangled-pair states (PEPS). Our method is based on variational PEPS optimization algorithms for two-dimensional quantum spin systems, and allows us to compute free energies directly in the thermo...

]]>While the phase transitions in binary propagation on complex networks have been studied a great deal from diverse fields during the past years, the effect of feedback has rarely been systematically addressed in a general manner. Here, we study a minimal network model of binary propagation with a gen...

]]>We study structural changes of adaptive networks in the coevolutionary susceptible-infected-susceptible (SIS) network model along its phase transition. We clarify to what extent these changes can be used as early-warning signs for the transition at the critical infection rate ${\lambda}_{c}$ at which the network...

]]>The geographical distribution of production is getting an increased amount of attention in economics. Distributed trade opens for production where it is cheapest, which in turn is reinforced by *economies of scale*. Using a simple agent-based model for the geographical interplay between transportation...

]]>Characteristic diffusion in a Lorentz gas system and its extensions are typically described through a scale-free order parameter. The relative validity of possible order parameters for the diffusion of a thick tracer rod through spherical scatterers in two and three dimensions as a function of the r...

]]>Slip flow in ducts and porous media is simulated using lattice-Boltzmann method incorporated with interfacial force models. The dependence of the results on the viscosity, LBM scheme (D3Q15 and D3Q19) and the relaxation time model (single- or multirelaxation time) is investigated. The severity of sp...

]]>We present a numerical study of the time-dependent motion of a two-dimensional vesicle in a channel under an imposed flow. In a Poiseuille flow the shape of the vesicle depends on the flow strength, the mechanical properties of the membrane, and the width of the channel as reported in the past. This...

]]>We show via particle-in-cell simulations that small normalized magnetic fields (${\omega}_{c}/{\omega}_{p}\ll 1$) can significantly modify the evolution of backward stimulated Raman scattering (SRS) in the kinetic regime due to the enhanced dissipation of nonlinear electron plasma waves propagating perpendicular to magnetic...

]]>A tomographic or image representation of three-dimensional (3D) porous media is a primary tool for the consistent correlation and prediction of multiple physical properties. For multiscale media a single imaging scale may not be sufficient, and a compromise between field of view and resolution is re...
