The purpose of this paper is to reveal the spread rules of the three pneumonia: COVID-19,
SARS and MERS. We compare the new spread characteristics of COVID-19 with those of …

In this paper, by taking full consideration of demographics, transfer from infectious to
susceptible and contact heterogeneity of the individuals, we construct an improved …

In this work, we provide a general mathematical formalism to study the optimal control of an
epidemic, such as the COVID-19 pandemic, via incentives to lockdown and testing. In …

Locating the propagation source is one of the most important strategies to control the
harmful diffusion process on complex networks. Most existing methods only consider the …

Consider an epidemic that propagates in a network of N individuals. The dynamics of the
infection are governed by the N-intertwined SIR model, which is a non-linear model. Our …

准确度量复杂网络中节点的重要度对于研究网络结构和功能等方面具有重要的指导意义.
现有多数节点重要度评估算法考虑了节点及其邻居节点的相关信息, 却忽略了节点间的拓扑结构 …

In this paper, a simplified discrete-time SIR model with nonlinear incidence and recovery
rates is discussed. Here, using the integral step size and the intervention level as control …

In this paper, we examined the codimension-two bifurcation analysis of a two-dimensional
discrete epidemic model. More precisely, we examined the codimension-two bifurcation …

Nowadays, viruses and worms create the most critical problems in computer security issues.
Hence, the spreading behavior of computer viruses and the investigation of their control …

The main aim to build models capable of simulating the spreading of infectious diseases is
to control them. And along this way, the key to find the optimal strategy for disease control is …
