Based on the statistical mechanics model, the coverage rate of the type I antifreeze protein (AFP) on the surface of ice-crystal in a protein solution is studied by including the adsorption orientation, as well as both the AFP–ice and AFP–water hydrophobic interactions. As an example, the...

This paper investigates how the introduction of heterogeneous relationships and the subsequent investment preference influences the evolution of cooperation in prisoner’s dilemma games. We consider random tie strength values drawn from distributions with different heterogeneity. We show that...

In recent years, online social networks (OSN) have emerged as a platform of sharing variety of information about people, and their interests, activities, events and news from real worlds. Due to the large scale and access limitations (e.g., privacy policies) of online social network services...

A method to introduce the damping terms in the equations of motion of magnetization in a material consists in defining a positive dissipative function that has a quadratic form in the velocities. The coefficients that appear in this dissipative function must be symmetric. The theory developed by...

Computer viruses are evolving by developing spreading mechanisms based on the use of multiple vectors of propagation. The use of the social network as an extra vector of attack to penetrate the security measures in IP networks is improving the effectiveness of malware, and have therefore been...

Unlike earthquake frequency that was proved following the Poisson distribution, seismic hazard (the annual rate of earthquake ground motions) is assumed to be the same type of random variables without tangible support. Instead of using total-probability algorithms currently employed, this study...

In this paper, we study the dynamics of a correlated continuous time random walk with time averaged waiting time. The mean square displacement (MSD) shows this process is subdiffusive and generalized Einstein relation holds. We also get the asymptotic behavior of the probability density function...

The presence of chaos in traffic flow is studied using a modified discrete dynamic coupled map model which is derived from both the flow–density–speed fundamental diagram and Del Castillo’s speed–density model. The modified model employs occupancy as its new variable and introduces a...

This paper concerns the magneto-fluid dynamics modeled by the stochastic flow where the turbulent term is driven by the random forcing. Magnetohydrodynamic (MHD) turbulence can be interpreted in terms of a standard map (SM), modeling perturbed Hamiltonian systems, to explain some of the features...

This work studies long-term autocorrelation asymmetries in the dynamics of crude oil markets for prices in the period from 1986 to 2014. Autocorrelations in crude oil price returns are quantified in terms of the Hurst exponent estimated with the rescaled range (R/S) method. The results obtained...
