Global properties of virus dynamics with B-cell impairment

open access: yesOpen Mathematics, 2019
In this paper we construct a class of virus dynamics models with impairment of B-cell functions. Two forms of the incidence rate have been considered, saturated and general. The well-posedness of the models is justified.

On modelling of epidemic childhood diseases with the Caputo-Fabrizio derivative by using the Laplace Adomian decomposition method

open access: yesAlexandria Engineering Journal, 2020
We present a fractional-order epidemic model for childhood diseases with the new fractional derivative approach proposed by Caputo and Fabrizio. By applying the Laplace Adomian decomposition method (LADM), we solve the problem and the solutions are ...

Exact controllability for nonlinear thermoviscoelastic plate problem

open access: yesDemonstratio 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 ...

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

open access: yesOpen 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

Growth of tumor due to Arsenic and its mitigation by black tea in Swiss albino mice

open access: yesAlexandria Engineering Journal, 2020
Inorganic arsenic causes carcinogenesis in a large part of the world. Its potential is elicited by the generation of ROS, which leads to damages to DNA, lipid and protein. Black tea, an antioxidant, can mitigate such deleterious effects by quenching ROS.

Consequences of Culling in Deterministic ODE Predator-Prey Models [PDF]

open access: yes
We show, within the context of the standard class of deterministic ODE predator-prey mathematical models, that predator culling does not produce a long term decrease in the predator population.
