The coronavirus disease 2019 (COVID-19) is a recent outbreak of respiratory infections that have affected millions of humans all around the world. Initially, the major intervention strategies used to combat the infection were the basic publ...
Modeling supply chain viability and adaptation against underload cascading failure during the COVID-19 pandemic [0.03%]
新冠肺炎疫情下供应链的欠载级联失效预警与阻断模型研究

Supply chain viability concerns the entire supply system rather than one company or one single chain to survive COVID-19 disruptions. Mobility restriction and overall demand decline lead to systematically cascading disruptions that are more...
Coevolving spreading dynamics of negative information and epidemic on multiplex networks [0.03%]
多层网络上负面信息与流行病的协同演化动力学

Jiaxing Chen et al.
The widespread dissemination of negative information on vaccine may arise people's concern on the safety of vaccine and increase their hesitancy in vaccination, which can seriously impede the progress of epidemic control. Existing works on ...
The fractional-order discrete COVID-19 pandemic model: stability and chaos [0.03%]
分数阶离散COVID-19流行病模型：稳定性与混沌现象
Abderrahmane Abbes,Adel Ouannas,Nabil Shawagfeh et al.
Abderrahmane Abbes et al.
This paper presents and investigates a new fractional discrete COVID-19 model which involves three variables: the new daily cases, additional severe cases and deaths. Here, we analyze the stability of the equilibrium point at different valu...
The effect of information-driven resource allocation on the propagation of epidemic with incubation period [0.03%]
基于信息的资源配置对具有潜伏期的流行病传播的影响研究
Xuzhen Zhu,Yuxin Liu,Xiaochen Wang et al.
Xuzhen Zhu et al.
In the pandemic of COVID-19, there are exposed individuals who are infected but lack distinct clinical symptoms. In addition, the diffusion of related information drives aware individuals to spontaneously seek resources for protection. The ...
The impact of the global and local awareness diffusion on epidemic transmission considering the heterogeneity of individual influences [0.03%]
考虑个体异质影响下全局局部awareness扩散对流行病传播的影响
Haidong Xu,Ye Zhao,Dun Han
Haidong Xu
In this paper, we propose a coupled awareness-epidemic spreading model considering the heterogeneity of individual influences, which aims to explore the interaction between awareness diffusion and epidemic transmission. The considered heter...

Higuchi's method of determining fractal dimension is an important, well-used, research tool that, compared to many other methods, gives rapid, efficient, and robust estimations for the range of possible fractal dimensions. One major shortco...
When might host heterogeneity drive the evolution of asymptomatic, pandemic coronaviruses? [0.03%]
宿主异质性可能何时会驱动无症状冠状病毒的进化？

Kenichi W Okamoto et al.
Controlling many infectious diseases, including SARS-Coronavirus-2 (SARS-CoV-2), requires surveillance followed by isolation, contact-tracing and quarantining. These interventions often begin by identifying symptomatic individuals. However,...
A multicompartment mathematical model to study the dynamic behaviour of COVID-19 using vaccination as control parameter [0.03%]
