Analysis of a hyperbolic geometric model for visual texture perception
Journal of Mathematical Neuroscience, 2011 We study the neural field equations introduced by Chossat and Faugeras to model the representation and the processing of image edges and textures in the hypercolumns of the cortical area V1.

Stability analysis in terms of two measures for dynamic systems on time scales
International Journal of Stochastic Analysis, Volume 6, Issue 4, Page 325-344, 1993., 1993 Using the theory of Lyapunov′s second method developed earlier for time scales, we extend our stability results to two measures which give rise to unification of several stability concepts in a single set up.

Effect of population migration and punctuated lockdown on the spread of infectious diseases
Nonautonomous Dynamical Systems, 2021 One of the critical measures to control infectious diseases is a lockdown. Once past the lockdown stage in many parts of the world, the crucial question now concerns the effects of relaxing the lockdown and finding the best ways to implement further ...

Effect of saturated treatment on malaria spread with optimal intervention
Alexandria Engineering Journal, 2023 This work presents a new deterministic model which considers transmission mode through blood transfusion and saturated treatment function with a view to gaining more insights into the dynamical spread of malaria.

International Journal of Stochastic Analysis, Volume 5, Issue 3, Page 261-274, 1992., 1991 Differential equations of the form y′ = f(t, y, y′), where f is not necessarily linear in its arguments, represent certain physical phenomena and solutions have been known for quite some time. The well known Clairut′s and Chrystal′s equations fall into this category.

Nonautonomous Dynamical Systems, 2021 In this paper, we formulate a temperature-dependent model for malaria transmission dynamics which includes immature stages of mosquitoes. The model is constructed by using ordinary differential equations with some parameters which are periodic functions.

Lyapunov stability theory for dynamic systems on time scales
International Journal of Stochastic Analysis, Volume 5, Issue 3, Page 275-281, 1992., 1992 By use of the necessary calculus and the fundamental existence theory for dynamic systems on time scales, in this paper, we develop Lyapunov′s second method in the framework of general comparison principle so that one can cover and include several stability results for both types of equations at the same time.

Computational and Mathematical Biophysics, 2023 The four-dimensional food-web system consisting of two prey species for a generalist middle predator and a top predator is proposed and investigated. The middle predator is predating over both the prey species with a modified Holling type-II functional ...

Mathematical modeling of Zika disease in pregnant women and newborns with microcephaly in Brazil
, 2017 We propose a new mathematical model for the spread of Zika virus. Special attention is paid to the transmission of microcephaly. Numerical simulations show the accuracy of the model with respect to the Zika outbreak occurred in Brazil.Comment: This is a ...
