An extended car following model is proposed by incorporating intelligent transportation system and the backward looking effect under certain condition in traffic flow. The neutral stability condition of this model is obtained by using the linear stability theory. The results show that...

The coverage of vicinal, stepped surfaces with molecules is simulated with the help of a two-dimensional Ising model including local distortions and an Ehrlich-Schwoebel barrier term at the steps. An effective two-spin model is capable to describe the main properties of this distorted Ising...

We study numerically the effect of sequence heterogeneity on the thermodynamic properties of a Poland-Scheraga model for DNA denaturation taking into account self-avoidance, i.e. with exponent c<Subscript>p</Subscript>=2.15 for the loop length probability distribution. In complement to previous on-lattice Monte Carlo...</subscript>

According to extensive experimental findings, the Ginzburg temperature t<Subscript>G</Subscript> for ionic fluids differs substantially from that of nonionic fluids [W. Schröer, H. Weigärtner, Pure Appl. Chem. <Emphasis Type="Bold">76, 19 (2004)]. A theoretical investigation of this outcome is proposed here by a mean field analysis of...</emphasis></subscript>

We apply a new entropic scheme to study the critical behavior of the square-lattice Ising model with nearest- and next-nearest-neighbor antiferromagnetic interactions. Estimates of the present scheme are compared with those of the Metropolis algorithm. We consider interactions in the range where...

Extensive Monte Carlo simulations are used to investigate the stability of the ferromagnetic ground state in three-dimensional systems of Ising dipoles with added quenched disorder. These systems model the collective ferromagnetic order observed in various systems with dipolar long-range...
