Non-local diffusion and pulse intervention in a faecal-oral model with moving infected fronts

Advances in Nonlinear Analysis
How individual dispersal patterns and human intervention behaviours affect the spread of infectious diseases constitutes a central problem in epidemiological research.

New parameters estimation in an ordinary differential equation model for the multistep transformation of cancer cells using particle swarm optimization

Computational and Mathematical Biophysics
The research on cancer cells has proposed many hypotheses as a basic conceptual framework for understanding how normal cells transform into cancer cells. Cancer cells are assumed to undergo a multilevel mutation process from normal cells to cancer cells.

Stability property of the prey free equilibrium point

Open Mathematics, 2019
We revisit a prey-predator model with stage structure for predator, which was proposed by Tapan Kumar Kar. By using the differential inequality theory and the comparison theorem of the differential equation, we show that the prey free equilibrium is ...

Modeling of the switching effect on two prey and one predator with the presence of Allee effects and refuge

Computational and Mathematical Biophysics
To examine the dynamics of a predator’s interaction with two prey species, this study develops a comprehensive mathematical model that accounts for ecological complexities, including the Allee effect, prey switching behavior, and prey refuge.

ON ESTIMATING THE CONTROL REPRODUCTION NUMBER OF ZIKA VIRUS DISEASE CONTROL MODEL

, 2019
In this paper, the possibility of stopping the spread of zika virus disease by introducing wolbachia-infected aedes aegypti mosquitoes in the zika endemic area is shown. A system of 14 nonlinear ordinary di erential equations is constructed, which models

Homogenization of Smoluchowski-type equations with transmission boundary conditions

Advanced Nonlinear Studies
In this work, we prove a two-scale homogenization result for a set of diffusion-coagulation Smoluchowski-type equations with transmission boundary conditions.

© Hindawi Publishing Corp. SUBTHRESHOLD DOMAIN OF BISTABLE EQUILIBRIA FOR A MODEL OF HIV EPIDEMIOLOGY

, 2002
A homogeneous-mixing population model for HIV transmission, which incorpo-rates an anti-HIV preventive vaccine, is studied qualitatively. The local and global stability analysis of the associated equilibria of the model reveals that the model can have ...

Metapopulation Dynamics with Migration and Local Competition

, 2002
MSC2000: primary 34D15, 34D23, 92B05; secondary 34K60, 34E13, 92D40.Many patch-based metapopulation models assume that the local population within each patch is at its equilibrium and independent of changes in patch occupancy.
