The evolution of resource distribution, slow diffusion, and dispersal strategies in heterogeneous populations

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
Population diffusion in river-ocean ecologies and for wild animals, including birds, mainly depends on the availability of resources and habitats. This study explores the dynamics of the resource-based competition model for two interacting species in ...

Existence and stability criteria for global synchrony and for synchrony in two alternating clusters of pulse-coupled oscillators updated to include conduction delays. [PDF]

open access: yesMath Biosci
Phase Response Curves (PRCs) have been useful in determining and analyzing various phase-locking modes in networks of oscillators under pulse-coupling assumptions, as reviewed in Mathematical Biosciences, 226:77-96, 2010.

Second-order sufficient conditions in the sparse optimal control of a phase field tumor growth model with logarithmic potential [PDF]

open access: yesE S A I M: Control, Optimisation and Calculus of Variations, 2023
This paper treats a distributed optimal control problem for a tumor growth model of viscous Cahn--Hilliard type. The evolution  of the tumor fraction is governed by a thermodynamic force induced by a double-well potential of logarithmic type.

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.

Global stability dynamics and sensitivity assessment of COVID-19 with timely-delayed diagnosis in Ghana

open access: yesComputational and Mathematical Biophysics, 2022
In this paper, we study the dynamical effects of timely and delayed diagnosis on the spread of COVID-19 in Ghana during its initial phase by using reported data from March 12 to June 19, 2020. The estimated basic reproduction number, ℛ0, for the proposed

Bifurcation and sensitivity analysis reveal key drivers of multistability in a model of macrophage polarization

open access: yesbioRxiv, 2020
In this paper, we present and analyze a mathematical model for polarization of a single macrophage which, despite its simplicity, exhibits complex dynamics in terms of multistability.
