Optimal COVID-19 epidemic strategy with vaccination control and infection prevention measures in Thailand [PDF]

open access: yesInfectious Disease Modelling, 2022
COVID-19 is a severe acute respiratory syndrome caused by the Coronavirus-2 virus (SARS-CoV-2). The virus spreads from one to another through droplets from an infected person, and sometimes these droplets can contaminate surfaces that may be another ...

Control of COVID-19 dynamics through a fractional-order model [PDF]

open access: yesAlexandria Engineering Journal, 2021
We investigate, through a fractional mathematical model, the effects of physical distance on the SARS-CoV-2 virus transmission. Two controls are considered in our model for eradication of the spread of COVID-19: media education, through campaigns ...

A fractional order model for Dual Variants of COVID-19 and HIV co-infection via Atangana-Baleanu derivative [PDF]

open access: yesAlexandria Engineering Journal, 2022
In this paper, a new mathematical model for dual variants of COVID-19 and HIV co-infection is presented and analyzed. The existence and uniqueness of the solution of the proposed model have been established using the well known Banach fixed point theorem.

Qualitative analysis of a reaction-diffusion SIRS epidemic model with nonlinear incidence rate and partial immunity [PDF]

open access: yesInfectious Disease Modelling, 2023
In this paper, a reaction-diffusion SIRS epidemic model with nonlinear incidence rate and partial immunity in a spatially heterogeneous environment is proposed. The well-posedness of the solution is firstly established. Then the basic reproduction number

Influence of incubation delays on COVID-19 transmission in diabetic and non-diabetic populations – an endemic prevalence case

open access: yesComputational and Mathematical Biophysics, 2023
The study of dynamics of diabetic population infected by COVID-19 is of pressing concern as people with diabetes are considered to be at higher risk of severe illness from COVID-19.

Modelling of a two prey and one predator system with switching effect

open access: yesComputational and Mathematical Biophysics, 2021
Prey switching strategy is adopted by a predator when they are provided with more than one prey and predator prefers to consume one prey over others. Though switching may occur due to various reasons such as scarcity of preferable prey or risk in hunting

Bifurcation and chaos in a discrete predator-prey system of Leslie type with Michaelis-Menten prey harvesting

open access: yesOpen Mathematics, 2022
In this paper, a discrete Leslie-Gower predator-prey system with Michaelis-Menten type harvesting is studied. Conditions on the existence and stability of fixed points are obtained.

Complex dynamics of a four-species food-web model: An analysis through Beddington-DeAngelis functional response in the presence of additional food

open access: yesComputational and Mathematical Biophysics, 2023
The four-dimensional food-web system consisting of two prey species for a generalist middle predator and a top predator is proposed and investigated. The middle predator is predating over both the prey species with a modified Holling type-II functional ...
