It is increasingly recognized that a key component of successful infection control efforts is
understanding the complex, two-way interaction between disease dynamics and human …

An ecosystem shifts to an alternative stable state when a threshold of accumulated pressure
(ie direct impact of environmental change or human activities) is exceeded. Detecting this …

A novel delayed fractional-order gene regulatory network model is proposed in this paper.
Firstly, the sum of delays is chosen as the bifurcation parameter, the conditions of the …

Empirical results indicate that inducible defenses of plants have effects on herbivore
populations. However, little is known about how inducible defenses of plants have …

In a predator-prey metapopulation, two traits are adversely related: synchronization and
persistence. A decrease in synchrony apparently leads to an increase in persistence and …

The popularity of the Web improves the growth of web threats. Formulating mathematical
models for accurate prediction of malicious propagation over networks is of great …

Hepatitis B is an infectious disease caused by the hepatitis B virus (HBV) which affects
livers. In this paper, we formulate a hepatitis B model to study the transmission dynamics of …

This study is aimed to investigate the melting of phase change material (PCM) in a
horizontal double pipe heat exchanger. The area between the pipes is filled with RT50 as …

An appropriate mathematical structure to describe the population dynamics is given by the
partial differential equations of reaction–diffusion type. The spatiotemporal dynamics and …

Empirical studies indicate that many populations of herbivorous insects exhibit periodic
outbreaks, but the intrinsic causes of this behavior are not well understood. Thus, in this …
