With the vaccination against Covid-19 now available, how vaccination campaigns influence
the mathematical modeling of epidemics is quantitatively explored. In this paper, the …

A simulation is needed to observe and indicate how much preventive measures influence
the pandemic flow, controlling and stopping it. This study succeeded in making a stochastic …

This paper portrays the exploitation/exploration of artificial intelligence (AI) inspired
computing to study the behavior of the multi-delay differential systems that revealed the …

The existing research models of SIQRS are often defined by linear incidence, ignoring the
impact of lagging public awareness during outbreaks of infectious diseases. Their research …

Although the incidence of measles has been significantly reduced through vaccination, it
remains an important public health problem. In this paper, a measles model with pulse …

Impulsive dynamical systems have become increasingly popular during the past decades
because they provide a natural framework for mathematical modeling of many real-world …

Finding a rumor source is a major issue in the analysis of social networks. In this problem,
the rumor source is usually estimated from a given diffusion snapshot. How to estimate the …

This paper focuses on the dynamical behaviors of two stochastic SVIR models with media
coverage. The first system is based on system perturbation. It is shown that the transmission …

In this short communication, we deal with an integrability analysis of nonlinear three-
dimensional differential systems. Right-hand sides of these systems are linear in one …

In this paper, we are concerned with the existence, nonexistence, and multiplicity of positive
solutions for a impulsive periodic boundary value problem with positive parameter λ λ. Using …
