By March 14th 2022, Spain is suffering the sixth wave of the COVID-19 pandemic. All the previous waves have been intimately related to the degree of imposed mobility restrictions and its consequent release. Certain factors explain the incid...

While understanding of periodic recurrent waves of Covid-19 epidemics would aid to combat the pandemics, quantitative analysis of data over a two years period from the outbreak, is lacking. The complexity of Covid-19 recurrent waves is rela...
How and to what extent does the anti-social behavior of violating self-quarantine measures increase the spread of disease? [0.03%]
违反隔离措施等不遵从抗疫指引的行为如何以及在多大程度上加剧了疫情蔓延？

COVID-19 has shown that quarantine (or self-isolation) may be the only available tool against an unknown infectious disease if neither an effective vaccine nor anti-viral medication is available. Motivated by the fact that a considerable nu...
The influence of quadratic Lévy noise on the dynamic of an SIC contagious illness model: New framework, critical comparison and an application to COVID-19 (SARS-CoV-2) case [0.03%]
二次Lévy噪声对SIC传染病模型动态的影响：新框架、关键比较及COVID-19 (SARS-CoV-2) 应用案例分析

Yassine Sabbar et al.
This study concentrates on the analysis of a stochastic SIC epidemic system with an enhanced and general perturbation. Given the intricacy of some impulses caused by external disturbances, we integrate the quadratic Lévy noise into our mod...
Empirical study and model simulation of global stock market dynamics during COVID-19 [0.03%]

To understand the transmission dynamics of any infectious disease outbreak, identification of influential nodes plays a crucial role in a complex network. In most infectious disease outbreaks, activities of some key nodes can trigger rapid ...
A study on prosocial behavior of wearing a mask and self-quarantining to prevent the spread of diseases underpinned by evolutionary game theory [0.03%]
基于进化博弈论的预防疾病传播的戴口罩和自我隔离利他行为研究

In the wake of COVID-19, mask-wearing practice and self-quarantine is thought to be the most effective means of controlling disease spread. The current study develops an epidemiological model based on the SEIR process that takes into accoun...
The interconnection between independent reactive control policies drives the stringency of local containment [0.03%]
独立反应控制政策之间的相互联系决定了局部防控的严格程度
