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.

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.

Nabla inequalities and permanence for a logistic integrodifferential equation on time scales

open access: yesOpen Mathematics, 2017
In this paper, by using the theory of calculus on time scales and some mathematical methods, several nabla dynamic inequalities on time scales are established. As an application, we apply the obtained results to a logistic integrodifferential equation on

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 ...

Modelling the Effects of Condom Use and Antiretroviral Therapy in Controlling HIV/AIDS among Heterosexuals, Homosexuals and Bisexuals

open access: yesComputational and Mathematical Methods in Medicine, Volume 11, Issue 3, Page 201-222, 2010., 2010
A deterministic compartmental sex‐structured HIV/AIDS model for assessing the effects of homosexuals and bisexuals in heterosexual settings in which homosexuality and bisexuality issues have remained taboo is presented. We extend the model to focus on the effects of condom use as a single strategy approach in HIV prevention in the absence of any other ...

A Study of Within-Host Dynamics of Dengue Infection incorporating both Humoral and Cellular Response with a Time Delay for Production of Antibodies

open access: yesComputational and Mathematical Biophysics, 2021
a. Background: Dengue is an acute illness caused by a virus. The complex behaviour of the virus in human body can be captured using mathematical models. These models helps us to enhance our understanding on the dynamics of the virus.

Optimal Control of Vertically Transmitted Disease: An Integrated Approach

open access: yesComputational and Mathematical Methods in Medicine, Volume 11, Issue 4, Page 369-387, 2010., 2010
We study the dynamics of a disease under administration of a vaccine and antiviral drug, where the disease transmits directly from the parents to the offspring (vertical transmission) and also through contact with infective individuals (horizontal transmission).

Dynamics of two-species delayed competitive stage-structured model described by differential-difference equations

open access: yesOpen Mathematics, 2019
Overf the last few years, by utilizing Mawhin’s continuation theorem of coincidence degree theory and Lyapunov functional, many scholars have been concerned with the global asymptotical stability of positive periodic solutions for the non-linear ...
