Mathematical Analysis of a Malaria Model with Partial Immunity to Reinfection

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
A deterministic model with variable human population for the transmission dynamics of malaria disease, which allows transmission by the recovered humans, is first developed and rigorously analyzed. The model reveals the presence of the phenomenon of backward bifurcation, where a stable disease‐free equilibrium coexists with one or more stable endemic ...

Modelling HIV/AIDS Epidemic among Men Who Have Sex with Men in China

open access: yesBioMed Research International, Volume 2013, Issue 1, 2013., 2013
A compartmental model with antiviral therapy was proposed to identify the important factors that influence HIV infection among gay men in China and suggest some effective control strategies. We proved that the disease will be eradicated if the reproduction number is less than one.

Process Completing Sequences for Resource Allocation Systems with Synchronization

open access: yesJournal of Control Science and Engineering, Volume 2012, Issue 1, 2012., 2012
This paper considers the problem of establishing live resource allocation in workflows with synchronization stages. Establishing live resource allocation in this class of systems is challenging since deciding whether a given level of resource capacities is sufficient to complete a single process is NP‐complete.

Mathematical Analysis of a Periodic Delay Differential System for Mosquito Population Suppression Using Wolbachia‐Infected Males Releases

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This paper presents a mathematical analysis of a nonautonomous delay differential system. This system models mosquito population dynamics under the influence of seasonal environmental fluctuations and a biological control strategy based on the continuous release of Wolbachia‐infected males.

On Conley′s fundamental theorem of dynamical systems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 26, Page 1397-1401, 2004., 2004
We generalize Conley′s fundamental theorem of dynamical systems in Conley index theory. We also conclude the existence of a regular index filtration for every Morse decomposition.

Dynamical Analysis of an HIV Infection Model Including Quiescent Cells and Immune Response

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 15, Page 14301-14315, October 2025.
ABSTRACT This research gives a thorough examination of a human immunodeficiency virus (HIV) infection model that includes quiescent cells and immune response dynamics in the host. The model, represented by a system of ordinary differential equations, captures the complex interaction between the host's immune response and viral infection.

Approximate inertial manifolds for nonlinear parabolic equations via steady‐state determining mapping

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 1, Page 1-24, 1995., 1993
For nonlinear parabolic evolution equations, it is proved that, under the assumptions of local Lipschitz continuity of nonlinearity and the dissipativity of semiflows, there exist approximate inertial manifolds (AIM) in the energy space and that the approximate inertial manifolds are constructed as the graph of the steady‐state determining mapping ...

Nonlocal Cooperative Behavior, Psychological Effects, and Collective Decision‐Making: An Exemplification With Predator–Prey Models

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12011-12037, August 2025.
ABSTRACT In bio‐social models, cooperative behavior has evolved as an adaptive strategy, playing multi‐functional roles. One of such roles in populations is to increase the success of the survival and reproduction of individuals and their families or social groups.
