The extinction and persistence of the stochastic SIS epidemic model with vaccination

Zhao, Yanan; Jiang, Daqing; O’Regan, Donal - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 20, pp. 4916-4927

In this paper, we discuss the dynamics of a stochastic SIS epidemic model with vaccination. When the noise is large, the infective decays exponentially to zero regardless of the magnitude of R0. When the noise is small, sufficient conditions for extinction exponentially and persistence in the...

On the thresholds, probability densities, and critical exponents of Bak–Sneppen-like models

Garcia, Guilherme J.M.; Dickman, Ronald - In: Physica A: Statistical Mechanics and its Applications 342 (2004) 1, pp. 164-170

We report a simple method to accurately determine the threshold and the exponent ν of the Bak–Sneppen (BS) model and … also investigate the BS universality class. For the random-neighbor version of the BS model, we find the threshold x∗=0 …
