While COVID-19 is rapidly propagating around the globe, the need for providing real-time
forecasts of the epidemics pushes fits of dynamical and statistical models to available data …

In this work, we investigate the stability of an SIR epidemic model with a generalized
nonlinear incidence rate and distributed delay. The model also includes vaccination term …

In this paper we have discussed about the dynamics of three species (two preys and one
predator) delayed predator–prey model with cooperation among the preys against …

Rumor cause unnecessary conflicts and confusion by misleading the cognition of the public,
its spreading has largely influence on human affairs. All kinds of rumors and people's …

In this paper, the global dynamics of an SEI epidemic model with constant immigration and
general nonlinear incidence function is investigated. It is shown that there is neither a …

We investigate the global behaviour of a SIRI epidemic model with distributed delay and
relapse. From the theory of functional differential equations with delay, we prove that the …

Subway emergency may lead to passengers' panic, especially under self‐organizing
circumstance, which will spread rapidly and have an adverse impact on the society. This …

Internet worms exploiting zero‐day vulnerabilities have drawn significant attention owing to
their enormous threats to Internet in the real world. To begin with, a worm propagation model …

A two‐city SIR epidemic model with transport‐related infections is proposed. Some good
analytical results are given for this model. If the basic reproduction number ℜ0γ≤ 1, there …

This work considers a multi-group epidemic SIR models with vaccination. The fluctuation of
the environment is taken into account by introducing both color noise and white noise to a …
