An epidemic model with density dependent parameters and vaccination
International Journal of Mathematics and Mathematical Sciences, Volume 19, Issue 4, Page 805-814, 1996., 1994 A model originally suggested by Greenhalgh [12] and later modified by that same author [13,14] is considered under the assumption that the transmission coefficient is inversely proportional to the total population size. The purpose of this study is to see the effect of this density dependent transmission coefficient on the stability criteria for the ...

Bifurcations for a deterministic SIR epidemic model in discrete time
, 2014 In this paper, we are concerned with the theoretical analysis of the bifurcations for a deterministic SIR epidemic model in discrete time. By deriving equations describing flows on the center manifolds, we discuss the transcritical bifurcation at the ...

GLOBAL STABILITY ANALYSIS FOR LASSA FEVER TRANSMISSION DYNAMICS WITH OPTIMAL CONTROL APPLICATION
International Journal of Apllied Mathematics, 2018 A mathematical model for transmission dynamics of Lassa fever with optimal control application is presented. The existence of region where the model is epidemiologically feasible is established with respect to the use of pesticide control measure. We use

Stability of a secondary dengue viral infection model with multi-target cells
Alexandria Engineering Journal, 2022 Dengue is one of the vector-borne diseases spread in most parts of the world. The number of infected individuals is increased each year. This paper proposes a mathematical model describing the secondary dengue viral infection in micro-environment.

The Effect of a Refractory Period on the Power Spectrum of Neuronal Discharge [PDF]
, 1995 The interspike intervals in steady-state neuron firing are assumed to be independently and identically distributed random variables. In the simplest model discussed, each interval is assumed to be the sum of a random neuron refractory period and a ...

Do Longer Delays Matter? The Effect of Prolonging Delay in CTL Activation [PDF]
, 2010 The activation of a specific immune response takes place in the lymphoid organs such as the spleen. We present here a simplified model of the proliferation of specific immune cells in the form of a single delay equation.

An Energetic Variational Approach for ion transport
, 2014 The transport and distribution of charged particles are crucial in the study of many physical and biological problems. In this paper, we employ an Energy Variational Approach to derive the coupled Poisson-Nernst-Planck-Navier-Stokes system.
