We investigate optimal strategies to defend valuable goods against the attacks of a thief. Given the value of the goods and the probability of success for the thief, we look for the strategy that assures the largest benefit to each player irrespective of the strategy of his opponent. Two...

As cell proliferation is limited due to the loss of telomere repeats in DNA of normal somatic cells during division, telomere attrition can possibly play an important role in determining the maximum life span of organisms as well as contribute to the process of biological ageing. With computer...

In this paper, a simple (2+1) solid-on-solid model of the epitaxial films growth based on random deposition followed by breaking particle–particle lateral bonds and particles surface diffusion is introduced. The influence of the critical number of the particle–particle lateral bonds z and...

The kink density and its influence on the growth velocity in the kinetic BCSOS model are studied using an exact finite-size analysis based on the transition matrix method and a kinetic Monte Carlo simulation at equilibrium and during growth. The bcc(001) surface fluctuates in the model through...

The influence of interaction and lattice coordination number on the reactivity and structure of adsorbed particles on a surface has been analysed for a reaction of a monomer and a dimer that dissociates, both of which are adsorbed on a surface and react. For the case without interaction there is...

Tracer and collective diffusion of repulsively interacting particles adsorbed on a bivariate trap surface are studied by means of Monte Carlo modelling. Adsorption isotherms are obtained via simulations in the grand-canonical ensemble. Simulations in the canonical ensemble are used to mimick...

We generate a porous structure by computer simulation in (2+1) dimension using a bidisperse ballistic deposition model. Particles of two different sizes are deposited randomly creating a porous bulk bounded by a highly irregular upper surface. The structure of the interface is connected to the...

In this work we study the problem of tax evasion on a fully-connected population. For this purpose, we consider that the agents may be in three different states, namely honest tax payers, tax evaders and undecided, that are individuals in an intermediate class among honests and evaders. Every...

Molecular dynamics simulations were performed for eight different metals to calculate their constant volume heat capacity and latent heat in both liquid and solid phases. The atomic interaction for the simulations is taken as modeled by the n-body semi-empirical Gupta potential. The per atom...

A CO+NO→CO2+12N2 surface reaction model is studied by means of Monte Carlo simulations. The surface is represented by triangular and square lattices and the diffusion of N and lateral interaction between reactant nearest-neighbor adatoms is considered. The influence of diffusion of N to...
