Biological and Mechanical Transmission Models of Dengue Fever

Communication in Biomathematical Sciences, 2019
Dengue fever disease is caused by the dengue virus and transmitted primarily by the Aedes aegypti mosquitoes. There is no vaccine available to prevent transmission of the disease until recently which makes 30% of the worlds population is at risk of the ...

Mathematical modelling and analysis of stochastic malaria and COVID-19 co-infection model

Applied Mathematics in Science and Engineering
In this article, we construct and analyse a stochastic mathematical model to study the co-infection dynamics of malaria and COVID-19 in a population. We derive the basic reproduction number associated with the disease-free equilibrium of the stochastic ...

Propagation dynamics for an epidemic patch model with variable incubation period

European Journal of Applied Mathematics
We study an epidemic patch model that describes the disease spread in population with variable latency due to the differences in immunologic tolerance between individuals. We focus on whether the disease can spread in space that leads to the emergence of

Estimation of spreading speeds and travelling waves for the lattice pioneer-climax competition system

Journal of Biological Dynamics
This paper concerns the invasion dynamics of the lattice pioneer-climax competition model with parameter regions in which the system is non-monotone. We estimate the spreading speeds and establish appropriate conditions under which the spreading speeds ...

Phase Reduction in the Noise Induced Escape Problem for Systems close to Reversibility

, 2013
We consider n-dimensional deterministic flows obtained by perturbing a gradient flow. We assume that the gradient flow admits a stable curve of stationary points, and thus if the perturbation is not too large the perturbed flow also admits an attracting ...

Absolute concentration robustness and multistationarity in reaction networks: Conditions for coexistence

European Journal of Applied Mathematics
Many reaction networks arising in applications are multistationary, that is, they have the capacity for more than one steady state, while some networks exhibit absolute concentration robustness (ACR), which means that some species concentration is the ...

The dynamical analysis of a nonlocal predator–prey model with cannibalism

European Journal of Applied Mathematics
Cannibalism is often an extreme interaction in the animal species to quell competition for limited resources. To model this critical factor, we improve the predator–prey model with nonlocal competition effect by incorporating the cannibalism term, and ...
