Stability analysis of fractional order SEIR model for malaria disease in Khyber Pakhtunkhwa

open access: yesDemonstratio Mathematica, 2021
We discussed stability analysis of susceptible-exposed-infectious-removed (SEIR) model for malaria disease through fractional order and check that malaria is epidemic or endemic in Khyber Pakhtunkhwa (Pakistan).

A Dynamic SIqIRV Mathematical model with Non-linear Force of Isolation, Infection and Cure

open access: yesNonautonomous Dynamical Systems, 2022
The Susceptible-Isolated-Infected-Recovered-Vaccinated (SIqIRV) deterministic model is examined in this paper. This model considers a nonlinear force of quarantine, infection and care, where vaccinated individuals lose their immunity after a period of ...

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 ...

A mathematical analysis of the impact of maternally derived immunity and double-dose vaccination on the spread and control of measles

open access: yesComputational and Mathematical Biophysics, 2023
Measles is a highly communicable viral infection that mostly affects children aged 5 years and below. Maternal antibodies in neonates help protect them from infectious diseases, including measles. However, maternal antibodies disappear a few months after

Existence and uniqueness of periodic orbits in a discrete model on Wolbachia infection frequency

open access: yesAdvances in Nonlinear Analysis, 2021
In this paper, we study a discrete model on Wolbachia infection frequency. Assume that a periodic and impulsive release strategy is implemented, where infected males are released during the first N generations with the release ratio α, and the release is

Low temperatures or high isolation delay increases the average COVID-19 infections in India : A Mathematical modeling approach

open access: yesComputational and Mathematical Biophysics, 2021
The dynamics of COVID-19 in India are captured using a set of delay differential equations by dividing a population into five compartments. The Positivity and Boundedness of the system is shown.

Metapopulation Dynamics with Migration and Local Competition [PDF]

open access: yes, 2002
MSC2000: primary 34D15, 34D23, 92B05; secondary 34K60, 34E13, 92D40.Many patch-based metapopulation models assume that the local population within each patch is at its equilibrium and independent of changes in patch occupancy.

An in-host model of HIV incorporating latent infection and viral mutation [PDF]

open access: yes, 2015
We construct a seven-component model of the in-host dynamics of the Human Immunodeficiency Virus Type-1 (i.e, HIV) that accounts for latent infection and the propensity of viral mutation. A dynamical analysis is conducted and a theorem is presented which
