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 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.

Vibrational properties characterization of mouse embryo during microinjection [PDF]

open access: yes, 2013
To determine the vibration characteristics (natural frequencies and mode shapes) of a mouse embryo during microinjection the modal analysis is used. The spherical mouse embryo 60 μm in diameter is modeled as elastic finite elements biostructure ...

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.

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

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 ...

Bifurcation-based parameter tuning in a model of the GnRH pulse and surge generator [PDF]

open access: yes, 2008
We investigate a model of the GnRH pulse and surge generator, with the definite aim of constraining the model GnRH output with respect to a physiologically relevant list of specifications. The alternating pulse and surge pattern of secretion results from
