Study of transmission pattern of COVID-19 among cardiac and noncardiac population using a nonlinear mathematical model

Computational and Mathematical Biophysics
Recent studies have intensified the risk of post-COVID-19 cardiovascular diseases. In an effort to understand the intricate dynamics of COVID-19 infection, this article suggests a four-compartment model to portray the dynamic interplay between the ...

Almost periodic solutions of a commensalism system with Michaelis-Menten type harvesting on time scales

Open Mathematics, 2019
In this paper, we consider an almost periodic commensal symbiosis model with nonlinear harvesting on time scales. We establish a criterion for the existence and uniformly asymptotic stability of unique positive almost periodic solution of the system. Our

Exact controllability for nonlinear thermoviscoelastic plate problem

Demonstratio Mathematica
In this article, we consider a problem of exact controllability in the processes described by a nonlinear damped thermoviscoelastic plate. First, we prove the global well-posedness result for the nonlinear functions that are continuous with respect to ...

A model of competing species that exhibits zip bifurcation

Revista Integración, 2017
The purpose of this paper is to present a concrete model of competing population species that exhibits a phenomenon called zip bifurcation. The Zip Bifurcation was introduced by Farkas in 1984 for a three dimensional ODE prey-predator system describing a
