Who Replaces Whom? Local versus Non-local Replacement in Social and Evolutionary Dynamics [PDF]

open access: yes, 2012
In this paper, we inspect well-known population genetics and social dynamics models. In these models, interacting individuals, while participating in a self-organizing process, give rise to the emergence of complex behaviors and patterns.

Global analysis of a cocirculating target cells HIV model with differential drug efficacy and nonlinear incidence rate

open access: yes, 2016
The main purpose of this work is to investigate the qualitative behavior of an HIV dynamics model with two types of cocirculating target cells. The model takes into account both short-lived and long lived chronically infected cells.

Dynamic control of modern, network-based epidemic models [PDF]

open access: yes, 2014
In this paper we make the first steps to bridge the gap between classic control theory and modern, network-based epidemic models. In particular, we apply nonlinear model predictive control (NMPC) to a pairwise ODE model which we use to model a ...

On variable-order hybrid FracInt Covid-19 mathematical model: optimal control approach

open access: yesArab Journal of Basic and Applied Sciences, 2023
An optimal control problem for the variable-order fractional-integer mathematical model of vaccination Covid 19 is presented in this research, where the order of the derivatives varies during the course of the time interval, becoming fractional or ...

STABILITY ANALYSIS OF THE EULER DISCRETIZATION FOR THE HARVESTING LESLIE-GOWER PREDATOR-PREY MODEL

open access: yes, 2015
In this paper, a harvesting Leslie-Gower equations is discretized using the forward Euler method. The dynamical properties of the resulted discrete system is then analysed.

On the dynamics of a class of multi-group models for vector-borne diseases [PDF]

open access: yes, 2015
The resurgence of vector-borne diseases is an increasing public health concern, and there is a need for a better understanding of their dynamics. For a number of diseases, e.g.

Do Longer Delays Matter? The Effect of Prolonging Delay in CTL Activation [PDF]

open access: yes, 2010
The activation of a specific immune response takes place in the lymphoid organs such as the spleen. We present here a simplified model of the proliferation of specific immune cells in the form of a single delay equation.

Mathematical Analysis of a Resource‐Based Dispersal Model With Gompertz Growth and Optimal Harvesting

open access: yesInternational Journal of Differential Equations, Volume 2025, Issue 1, 2025.
Gompertz dynamics offer significant applications for the growth of invasive species, cancer modeling, optimal harvesting policies, sustainable yield, and maintaining population levels due to its pattern formation in low‐density cases. This paper examines a widely applicable nonhomogeneous diffusive Gompertz law with zero Neumann boundary conditions ...

On Kinetic Equations Modeling Evolution of Systems in Mathematical Biology

open access: yes, 2013
We develop a rigorous formalism for the description of the kinetic evolution of interacting entities modeling systems in mathematical biology within the framework of the evolution of marginal observables.

Delay-induced patterns in a two-dimensional lattice of coupled oscillators [PDF]

open access: yes, 2014
We show how a variety of stable spatio-temporal periodic patterns can be created in 2D-lattices of coupled oscillators with non-homogeneous coupling delays.
