Yunbo Tu et al.
In this paper, a reaction-diffusion COVID-19 model is proposed to explore how vaccination-isolation strategies affect the development of the epidemic. First, the basic dynamical properties of the system are explored. Then, the system's asym...

Calistus N Ngonghala et al.
The effectiveness of control interventions against COVID-19 is threatened by the emergence of SARS-CoV-2 variants of concern. We present a mathematical model for studying the transmission dynamics of two of these variants (Delta and Omicron...
Exploring meteorological impacts based on Köppen-Geiger climate classification after reviewing China's response to COVID-19 [0.03%]
基于对中国应对COVID-19的回顾，基于Köppen-Geiger气候分类探讨气象影响
Fangyuan Chen,Siya Chen,Mengmeng Jia et al.
Fangyuan Chen et al.
More than 30 months into the novel coronavirus 2019 (COVID-19) pandemic, efforts to bring this prevalence under control have achieved tentative achievements in China. However, the continuing increase in confirmed cases worldwide and the nov...
Spatial and temporal dynamics of SARS-CoV-2: Modeling, analysis and simulation [0.03%]

A reaction-diffusion viral infection model is formulated to characterize the infection process of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a heterogeneous environment. In the model, the viral production, infection...
Zonal modeling of air distribution impact on the long-range airborne transmission risk of SARS-CoV-2 [0.03%]
分区模型中空气分布对SARS-CoV-2长程气溶胶传播风险的影响
Amar Aganovic,Guangyu Cao,Jarek Kurnitski et al.
Amar Aganovic et al.
A widely used analytical model to quantitatively assess airborne infection risk is the Wells-Riley model which is limited to complete air mixing in a single zone. However, this assumption tends not to be feasible (or reality) for many situa...
A possibilistic-robust-fuzzy programming model for designing a game theory based blood supply chain network [0.03%]
基于博弈论的血液供应链网络设计的Possibilistic-Robust-Fuzzy编程模型
Peiman Ghasemi,Fariba Goodarzian,Ajith Abraham et al.
Peiman Ghasemi et al.
This paper presents a bi-level blood supply chain network under uncertainty during the COVID-19 pandemic outbreak using a Stackelberg game theory technique. A new two-phase bi-level mixed-integer linear programming model is developed in whi...
Assessing the Impact of Contact Tracing, Quarantine and Red Zone on the Dynamical Evolution of the Covid-19 Pandemic using the Cellular Automata Approach and the Resulting Mean Field System: A Case study in Mauritius [0.03%]
基于元胞自动机方法和由此产生的平均场系统评估毛里求斯新冠肺炎疫情期间密切接触者追踪、隔离和红区设置对疫情动态演变的影响
Yusra Bibi Ruhomally,Maheshsingh Mungur,Abdel Anwar Hossen Khoodaruth et al.
Yusra Bibi Ruhomally et al.
A cellular automaton (CA) depicting the dynamics of the Covid-19 pandemic, is set up. Unlike the classic CA models, the present CA is an enhanced version, embodied with contact tracing, quarantine and red zones to model the spread of the Co...
There exists the "smartest" movement rate to control the epidemic rather than "city lockdown" [0.03%]
存在最优的“限流”措施而非“一刀切”的“封城”措施
