This article studies the global prescribed-time stabilization problem for a class of time-delay
nonlinear systems with uncertain parameters. First, we design two time-varying gains with …

We consider general virus dynamics model with virus‐to‐target and infected‐to‐target
infections. The model is incorporated by intracellular discrete or distributed time delays. We …

A stochastic prey‐predator system in a polluted environment with Beddington‐DeAngelis
functional response is proposed and analyzed. Firstly, for the system with white noise …

The initial focus of our research was to study the distribution of zero in a fifth-degree
exponential polynomial. Subsequently, we utilized the findings to examine the impact of …

Volume delay functions (VDFs) are mathematical relationships used by the traffic allocation
step of demand forecasting models to take into account the effect of increased traffic flow on …

Hepatitis B is a liver disease caused by the human hepatitis B virus (HBV). Mathematical
models help further the understanding of the processes involved and help make predictions …

We consider a general class of nonlinear dynamical systems with memory. We prove under
which conditions periodic perturbations allow solutions with the same period. In particular …

In this paper we derive some criteria of global attraction to a positive equilibrium for the
equation\begin {equation*} x'(t)=-\beta x (t)+\beta F (x (t-\sigma), x (t-\tau)),\end {equation*} …

In this paper we extend the classical “decomposing+ embedding” method for systems of
delay differential equations. Our extension has two advantages:(1) enhancing the range of …

The growth of the world population's number leads to increasing food needs. However, plant
diseases can decrease the production and quality of agricultural harvests. Mathematical …
