Mean square exponential and non-exponential asymptotic stability of impulsive stochastic Volterra equations

Journal of Inequalities and Applications, 2011
In this article, some inequalities on convolution equations are presented firstly. The mean square stability of the zero solution of the impulsive stochastic Volterra equation is studied by using obtained inequalities on Liapunov function, including mean

Stochastic optimal and time-optimal control studies for additional food provided prey–predator systems involving Holling type III functional response

Computational and Mathematical Biophysics, 2023
This article consists of a detailed and novel stochastic optimal control analysis of a coupled non-linear dynamical system. The state equations are modelled as an additional food-provided prey–predator system with Holling type III functional response for

Roosting ecology of endangered plant‐roosting bats on Okinawa Island: Implications for bat‐friendly forestry practices

Ecology and Evolution, Volume 11, Issue 20, Page 13961-13971, October 2021., 2021
We investigated the roosting ecology of two threatened island bats: the Ryukyu tube‐nosed bat Murina ryukyuana and Yanbaru whiskered bat Myotis yanbarensis. Murina ryukyuana roosted primarily in understory foliage, using tree cavities more often as maternity roosts, while M.

The effect of public health awareness and behaviors on the transmission dynamics of syphilis in Northwest China, 2006–2018, based on a multiple-stages mathematical model

Infectious Disease Modelling, 2021
Syphilis, a sexually transmitted infectious disease caused by the bacterium treponema pallidum, has re-emerged as a global public health issue with an estimated 12 million people infected each year.

From ODE to Open Markov Chains, via SDE: an application to models for infections in individuals and populations

Computational and Mathematical Biophysics, 2020
We present a methodology to connect an ordinary differential equation (ODE) model of interacting entities at the individual level, to an open Markov chain (OMC) model of a population of such individuals, via a stochastic differential equation (SDE ...

Coexistence for a kind of stochastic three-species competitive models

Open Mathematics, 2019
The coexistence of species sustains the ecological balance in nature. This paper focuses on sufficient conditions for the coexistence of a three-species stochastic competitive model, where the model has non-linear diffusion parts.

Uniform Convergence in some Limit Theorems for Multiple Particle Systems

, 1996
For n particles diffusing throughout R (or R d ), let j n;t (A), A 2 B, t 0, be the random measure that counts the number of particles in A at time t.

Analysis of a fractional-order prey-predator model with prey refuge and predator harvest using the consumption number: Holling type III functional response

Computational and Mathematical Biophysics
In this article, we study a fractional-order prey-predator model incorporating prey refuge and predator harvesting, employing a Holling type III functional response.

An alternative approach to modelling relapse in cancer with an application to adencarcinoma of the prostate

, 2006
This paper proposes an alternative approach to modelling relapse in cancer. In particular, the dynamic model for the tumor or biomarker will be subjected to a lower elastic boundary at which the process either will be absorbed or reflected.

Analytic solution of a fractional-order hepatitis model using Laplace Adomian decomposition method and optimal control analysis

Computational and Mathematical Biophysics
Infectious illnesses like hepatitis place a heavy cost on global health, and precise mathematical models must be created in order to understand and manage them.
