A Stochastic Model of Icosahedral Capsid Growth
Computational and Mathematical Methods in Medicine, Volume 6, Issue 2, Page 95-97, 2005., 2005 A model of growth of icosahedral capsids is proposed. It is similar to the stochastic model of fullerene growth, but takes into account variations in the composition of pentamers and hexamers that are responsible for the final capsid size. We show that the observed high yield of capsid production implies a high level of self‐organization of the ...

Nabla inequalities and permanence for a logistic integrodifferential equation on time scales
Open Mathematics, 2017 In this paper, by using the theory of calculus on time scales and some mathematical methods, several nabla dynamic inequalities on time scales are established. As an application, we apply the obtained results to a logistic integrodifferential equation on

Prey-predator model in drainage system with migration and harvesting
Nonautonomous Dynamical Systems, 2021 In this paper, we consider a prey-predator model with a reserve region of predator where generalist predator cannot enter. Based on the intake capacity of food and other factors, we introduce the predator population which consumes the prey population ...

Effect of randomly fluctuating environment on autotroph‐herbivore model system
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 68, Page 3703-3716, 2004., 2004 First we deal with a brief introduction of the autotroph‐herbivore model system along with deterministic analysis of local stability, bifurcation behavior, and persistence of the populations. The second part consists of the stochastic formulation of the model system to incorporate the effect of environmental fluctuation and then analysis of ...

On numerical study of Parkinson tremor
bioRxiv, 2016 Parkinson’s disease and Parkinson’s tremor are the two most common movement disorders, nor do we fully understand the origin of one of the disease’s cardinal symptom: the Parkinsonian tremor.

Subthreshold domain of bistable equilibria for a model of HIV epidemiology
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 58, Page 3679-3698, 2003., 2003 A homogeneous‐mixing population model for HIV transmission, which incorporates 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 multiple stable equilibria simultaneously.

Metapopulation Dynamics with Migration and Local Competition [PDF]
, 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.

ON THE OBSERVABILITY AND STATE ESTIMATION IN A CLASS OF GENE-EXPRESSION SYSTEM
Dynamic systems and applications, 2018 The failure of available physical sensors for the online measurement of protein concentration in cells is a key problem to understanding the transition in bio-systems.

The generalized Turner‐Bradley‐Kirk‐Pruitt equation
International Journal of Mathematics and Mathematical Sciences, Volume 32, Issue 2, Page 73-80, 2002., 2002 Several recent results pertaining to nonlinear equations of ecology are applied to a generalization of the Turner‐Bradley‐Kirk‐Pruitt (TBKP) equation, which illustrates a variety of interesting possibilities as regards persistence and extinction. The chief novelty consists in exploiting the value set of the equation, that is, the set of values taken on

An eco-epidemiological model with predator switching behavior
Computational and Mathematical Biophysics, 2023 Switching mechanism is adopted by predator populations when they are provided with two types of prey: susceptible and infected. In this study, we propose a modification of an eco-epidemiological model with the predator switching mechanism.
