Global dynamics for a model of amyloid fibril formation in pancreatic islet beta cells subjected to a therapy

open access: yesJournal of Biological Dynamics, 2020
Amyloid polypeptide (IAPP) fibril formation is the main cause of type II diabetes mellitus (T2DM) disease and cardiovascular disease (CVD). Therefore, implementing therapeutic interventions strategies to control IAPP fibril formation plays a crucial role

An ecoepidemic model with healthy prey herding and infected prey drifting away

open access: yesNonlinear Analysis, 2023
We introduce here a predator–prey model where the prey are affected by a disease. The prey are assumed to gather in herds, while the predators are loose and act on an individualistic basis.

Periodic Behaviour of an Epidemic in a Seasonal Environment with Vaccination

open access: yesMathematics, 2023
Infectious diseases include all diseases caused by the transmission of a pathogenic agent such as bacteria, viruses, parasites, prions, and fungi. They, therefore, cover a wide spectrum of benign pathologies such as colds or angina but also very serious ...

Mathematical Analysis of a Bacterial Competition in a Continuous Reactor in the Presence of a Virus

open access: yesMathematics, 2023
In this paper, we discuss the competition of two species for a single essential growth-limiting nutriment with viral infection that affects only the first species.

Effects of Media Coverage on Global Stability Analysis and Optimal Control of an Age-Structured Epidemic Model with Multi-Staged Progression

open access: yesMathematics, 2022
In this paper, a hybrid SEIAM model for infectious disease with a continuous age structure is established, where combined dynamic effects of media coverage and multi-staged infected progression on threshold dynamics are discussed.

Bacterial Competition in the Presence of a Virus in a Chemostat

open access: yesMathematics, 2023
We derive a mathematical model that describes the competition of two populations in a chemostat in the presence of a virus. We suppose that only one population is affected by the virus.

The effect of vector control strategy against Dengue transmission between mosquitoes and humans

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
With the consideration of mechanism of prevention and control for the spread of dengue fever, a mathematical model of dengue fever dynamical transmission between mosquitoes and humans, incorporating a vector control strategy of impulsive culling of ...

Analysis of a diffusive host-pathogen model with standard incidence and distinct dispersal rates

open access: yesAdvances in Nonlinear Analysis, 2020
This paper concerns with detailed analysis of a reaction-diffusion host-pathogen model with space-dependent parameters in a bounded domain. By considering the fact the mobility of host individuals playing a crucial role in disease transmission, we ...

Global behavior of Heroin epidemic model with time distributed delay and nonlinear incidence function

open access: yesResults in Physics, 2021
In this research, we investigate the global properties of the heroin epidemic model with time distributed delay and nonlinear incidence function. We show that the system has threshold dynamics in terms of R0, and we prove, a Lyapunov function, that for ...

Dynamics analysis of an HIV infection model with latent reservoir, delayed CTL immune response and immune impairment

open access: yesNonlinear Analysis, 2022
In this paper, we propose an HIV model with latent reservoir, delayed CTL immune response and immune impairment in which both virus-to-cell infection and cell-to-cell viral transmission are considered.
