The quantitative knowledge of interface anisotropy in lattice models is a major issue, both for the parametrization continuum models, and analysis experimental observations. In this paper, we focus on line tension stiffness, which plays role equilibrium shapes fluctuations, selection nonequilibrium growth patterns. We consider 2D Ising Hamiltonian square with first second-nearest-neighbor inter...

The beta delayed deuteron emission from 6He is studied in a dynamical microscopic cluster model. This model gives a reasonably good description for all the subsystems of 6He and 6Li in a coherent way, without any free parameter. The beta decay transition probability to the 6Li ground state is underestimated by a few percents. The theoretical beta delayed deuteron spectrum is close to experiment...

Mathematical models of the spread epidemic diseases are studied, paying special attention to networks. We treat Susceptible-Infected-Recovered (SIR) model and Susceptible-Exposed-Infectious-Recovered (SEIR) described by differential equations. perform microscopic numerical simulations for corresponding on Comparing a random network scale-free infection, we emphasize role hubs in network. also p...

PURPOSE We investigated the autofluorescence (AF) signature of the microscopic features of retina with age-related macular degeneration (AMD) using 488 nm excitation. METHODS The globes of four donors with AMD and four age-matched controls were embedded in paraffin and sectioned through the macula. Sections were excited using a 488 nm argon laser, and the AF emission was captured using a lase...
