Plankton interaction model: Effect of prey refuge and harvesting

Computational and Mathematical Biophysics
Harmful algal blooms are one of the major threats to aquatic ecosystem. Some phytoplankton species produce toxins during algal bloom and affect other aquatic species as well as human beings.

Analysis of backward bifurcation induced by nonlinear vertical transmission in COVID-19 dynamics with optimal control

Computational and Mathematical Biophysics
A mathematical model is designed to investigate transmission dynamics of COVID-19 in a setting where both horizontal and vertical transmission of COVID-19 occur concurrently.

A muscle crossbridge theory with internal crossbridge dynamics

Computational and Mathematical Biophysics
We develop a crossbridge model in which an attached crossbridge behaves like a linear spring with a variable rest length. We assume in particular that the rest length has a linear force–velocity relation, and that the force and rest length are both zero ...

Dynamic ecological system measures

Results in Applied Mathematics, 2019
The system decomposition theory has recently been developed for the dynamic analysis of nonlinear compartmental systems. The application of this theory to the ecosystem analysis has also been introduced in a separate article.

Role of limited medical resources in an epidemic model with media report and general birth rate

Infectious Disease Modelling
This paper formulates an SEIRSHM epidemic model with general birth rate, media report and limited medical resources. Firstly, the well-posedness of the solutions and the extinction of the disease are discussed.

Biological and Mechanical Transmission Models of Dengue Fever

Communication in Biomathematical Sciences, 2019
Dengue fever disease is caused by the dengue virus and transmitted primarily by the Aedes aegypti mosquitoes. There is no vaccine available to prevent transmission of the disease until recently which makes 30% of the worlds population is at risk of the ...

Mathematical modelling and analysis of stochastic malaria and COVID-19 co-infection model

Applied Mathematics in Science and Engineering
In this article, we construct and analyse a stochastic mathematical model to study the co-infection dynamics of malaria and COVID-19 in a population. We derive the basic reproduction number associated with the disease-free equilibrium of the stochastic ...
