Mathematical Modeling and Optimal Control of the Dynamics of an Internal Radicalization Process
Abstract and Applied Analysis, Volume 2025, Issue 1, 2025.This study presents a deterministic system of differential equations to model the internal radicalization process. Unlike previous models, we explicitly incorporate the subpopulation of eligibles, individuals who have experienced negative interactions with state institutions due to factors such as corruption, inequality, and poor governance.

International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.In ecological point of view, fears from predator may reduce the reproduction of prey and harvesting and intraspecific competition among predators, may changes the behavior of dynamical interaction between predator and their prey. In this paper, a Holling Type II prey–predator model with SI‐type of disease in prey has been modified and analyzed. Firstly,

The Dynamical Analysis of Food‐Web System With a Group Defense and Antipredator Property
International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.Prey employ group defense as a tactic to increase their chances of escaping predator attacks. Antipredator behavior, which involves synchronized movements and heightened awareness to deceive predators, may result from it. When one prey species has group defensive systems while the other does not, there is a complex interaction between two competing ...

Local Bifurcation and Global Stability of Two‐Prey‐One‐Predator Model
International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.This paper deals with dynamical analysis of an ecological model. This model includes two logistically growing prey species, namely, Prey X and Prey Y, and the third species Z behaves as the predator, predating both Prey X and Prey Y according to the extended Holling type‐II functional response.

Journal of Applied Mathematics, Volume 2025, Issue 1, 2025.In an ecological point of view, fears from predator cause physiological changes of prey population and these physiological changes may reduce the reproduction of prey. This paper deals with studying the effect of fear that is incorporated in the growth rate of prey on the dynamics of a delay ecological model consisting of two logistically growing prey ...

Journal of Mathematics, Volume 2025, Issue 1, 2025.Considering the low cost and minimal environmental impact, nonlinear impulsive biological control strategies are more consistent with the pest management. From this basic standpoint, we formulate a pest control model incorporating delayed stage structure for the pest population and nonlinear impulsive release of natural enemies, and then conduct a ...

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 104, Issue 3, March 2024.Abstract We derive and investigate a stationary model for the electrothermal behavior of organic thin‐film devices including their electrical and thermal environment. Whereas the electrodes are modeled by Ohm's law, the electronics of the organic device itself is described by a generalized van Roosbroeck system with temperature‐dependent mobilities and

Analysis of Prey‐Predator Scheme in Conjunction with Help and Gestation Delay
Journal of Mathematics, Volume 2024, Issue 1, 2024.This paper presents a three‐dimensional continuous time dynamical system of three species, two of which are competing preys and one is a predator. We also assume that during predation, the members of both teams of preys help each other and the rate of predation of both teams is different.

Mathematical Problems in Engineering, Volume 2024, Issue 1, 2024.Malaria is a complex disease with many factors influencing the transmission dynamics, including age. This research analyzes the transmission dynamics of malaria by developing an age‐structured mathematical model using the classical integer order and Atangana–Baleanu–Caputo fractional operators.
