Orbital stability and Zhukovskiǐ quasi-stability in impulsive dynamical systems

open access: yesOpen Mathematics, 2022
In this article, we deal with orbital stability and Zhukovskiǐ quasi-stability of periodic or recurrent orbits in an impulsive dynamical system defined in the n-dimensional Euclidean space Rn{{\mathbb{R}}}^{n}.

An eco-epidemiological model with predator switching behavior

open access: yesComputational 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.

A mathematical model to study the spread of COVID-19 and its control in India

open access: yesComputational and Mathematical Biophysics, 2023
In this article, a nonlinear mathematical model is proposed and analyzed to study the spread of coronavirus disease (COVID-19) and its control. Due to sudden emergence of a peculiar kind of infection, no vaccines were available, and therefore, the ...

A mathematical analysis of the impact of maternally derived immunity and double-dose vaccination on the spread and control of measles

open access: yesComputational and Mathematical Biophysics, 2023
Measles is a highly communicable viral infection that mostly affects children aged 5 years and below. Maternal antibodies in neonates help protect them from infectious diseases, including measles. However, maternal antibodies disappear a few months after

Dynamical analysis of a Lotka Volterra commensalism model with additive Allee effect

open access: yesOpen Mathematics, 2022
We propose and analyze a Lotka-Volterra commensal model with an additive Allee effect in this article. First, we study the existence and local stability of possible equilibria.

Within-host models of dengue virus transmission with immune response

open access: yesComputational and Mathematical Biophysics, 2023
Dengue fever is an infectious viral fever. The complex behavior of the virus within the body can be explained through mathematical models to understand the virus’s dynamics.

Gene Content and Distribution in the Nuclear Genome of Fragaria vesca

open access: yesThe Plant Genome, Volume 2, Issue 1, March 2009., 2009
Thirty fosmids were randomly selected from a library of Fragaria vesca subsp. americana (cv. Pawtuckaway) DNA. These fosmid clones were individually sheared, and ∼4‐ to 5‐kb fragments were subcloned. Subclones on a single 384‐well plate were sequenced bidirectionally for each fosmid. Assembly of these data yielded 12 fosmid inserts completely sequenced,

Global analysis and control for a vector-borne epidemic model with multi-edge infection on complex networks

open access: yesOpen Mathematics, 2023
In this study, a vector-borne epidemic model with multi-edge infection on complex networks is built. Using the method of next-generation matrix, the basic reproduction number R0{R}_{0} is calculated, and if R01{R}_{0}\gt 1, there exists a unique endemic ...
