Stochastic Lotka–Volterra mutualism model with jumps
Modern Stochastics: Theory and ApplicationsThe existence and uniqueness of the global positive solution are proved for the system of stochastic differential equations describing a two-species Lotka–Volterra mutualism model disturbed by white noise, centered and noncentered Poisson noises. For the

Dynamics Analysis of a Stochastic Delay Gilpin-Ayala Model with Markovian Switching
Discrete Dynamics in Nature and Society, 2019 This paper considers a stochastic delay Gilpin-Ayala model with Markovian switching. Using Lyapunov method, we show existence and uniqueness of global positive solution.

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Survival Analysis of a Nonautonomous Logistic Model with Stochastic Perturbation
Journal of Applied Mathematics, 2012 Taking white noise into account, a stochastic nonautonomous logistic model is proposed and investigated. Sufficient conditions for extinction, nonpersistence in the mean, weak persistence, stochastic permanence, and global asymptotic stability are ...

Asymptotic properties of a stochastic nonautonomous competitive system with impulsive perturbations
Advances in Difference Equations, 2017 In this paper, a generalized nonautonomous stochastic competitive system with impulsive perturbations is studied. By the theories of impulsive differential equations and stochastic differential equations, we have established some asymptotic properties of
