Global stability of a delayed SARS-CoV-2 reactivation model with logistic growth, antibody immunity and general incidence rate [PDF]

open access: yesAlexandria Engineering Journal, 2022
Mathematical models have been considered as a robust tool to support biological and medical studies of the coronavirus disease 2019 (COVID-19). This new disease is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Modeling and prediction of the third wave of COVID-19 spread in India

open access: yesComputational and Mathematical Biophysics, 2022
In this work, we proposed a simple SEIHR compartmental model to study and analyse the third wave of COVID-19 in India. In addition to the other features of the disease, we also consider the reinfection of recovered individuals in the model.

Dynamics of an eco-epidemic model with Allee effect in prey and disease in predator

open access: yesComputational and Mathematical Biophysics, 2023
In this work, the dynamics of a food chain model with disease in the predator and the Allee effect in the prey have been investigated. The model also incorporates a Holling type-III functional response, accounting for both disease transmission and ...

Orbital stability and Zhukovskiǐ quasi-stability in impulsive dynamical systems

open access: yesOpen Mathematics, 2022
In this article, we deal with orbital stability and Zhukovskiǐ quasi-stability of periodic or recurrent orbits in an impulsive dynamical system defined in the n-dimensional Euclidean space Rn{{\mathbb{R}}}^{n}.

An eco-epidemiological model with predator switching behavior

open access: yesComputational and Mathematical Biophysics, 2023
Switching mechanism is adopted by predator populations when they are provided with two types of prey: susceptible and infected. In this study, we propose a modification of an eco-epidemiological model with the predator switching mechanism.
