Since November 2021, there have been cases of COVID-19's Omicron strain spreading in competition with Delta strains in many parts of the world. To explore how these two strains developed in this competitive spread, a new compartmentalized m...
Hopf bifurcation without parameters in deterministic and stochastic modeling of cancer virotherapy, part II [0.03%]

In part II, we analyze our stochastic model which incorporates microenvironmental noises and uncertainties related to immune responses. Outcomes of the therapy in our model are largely determined by the infectivity constant, the infection v...

We derive a generalization of the Rogers generating function for the continuous q-ultraspherical/Rogers polynomials whose coefficient is a 2 ϕ 1. From that expansion, we derive corresponding specialization and limit transition expansions f...

The paper presents one of the possible approaches to pandemic spread modeling. The proposed model is based on the mean-field control inside separate groups of population, namely, suspectable (S), infected (I), removed (R) and cross-immune (...
Modelling the impact of reopening schools in the UK in early 2021 in the presence of the alpha variant and with roll-out of vaccination against SARS-CoV-2 [0.03%]
在阿尔法变异株出现及SARS-CoV-2疫苗接种 rollout背景下， modelling 2021年初英国学校复课的影响
J Panovska-Griffiths,R M Stuart,C C Kerr et al.
J Panovska-Griffiths et al.
Following the resurgence of the COVID-19 epidemic in the UK in late 2020 and the emergence of the alpha (also known as B117) variant of the SARS-CoV-2 virus, a third national lockdown was imposed from January 4, 2021. Following the decline ...
A population structure-sensitive mathematical model assessing the effects of vaccination during the third surge of COVID-19 in Italy [0.03%]
一种人口结构敏感的数学模型评估了在意大利新冠第三波大流行期间疫苗接种的效果
Pablo Jiménez-Rodríguez,Gustavo A Muñoz-Fernández,José C Rodrigo-Chocano et al.
Pablo Jiménez-Rodríguez et al.
We provide a non-autonomous mathematical model to describe some of the most relevant parameters associated to the COVID-19 pandemic, such as daily and cumulative deaths, active cases, and cumulative incidence, among others. We will take int...
Learning delay dynamics for multivariate stochastic processes, with application to the prediction of the growth rate of COVID-19 cases in the United States [0.03%]
用于预测美国COVID-19病例增长率的多变量随机过程延迟动态学习
Paromita Dubey,Yaqing Chen,Álvaro Gajardo et al.
Paromita Dubey et al.
Delay differential equations form the underpinning of many complex dynamical systems. The forward problem of solving random differential equations with delay has received increasing attention in recent years. Motivated by the challenge to p...
Mathematical analysis and topology of SARS-CoV-2, bonding with cells and unbonding [0.03%]
SARS-CoV-2的数学分析及拓扑结构，与细胞的结合和分离

Arni S R Srinivasa Rao
We consider the structure of the novel coronavirus (SARS-Cov-2) in terms of the number of spikes that are critical in bonding with the cells in the host. Bonding formation is considered for selection criteria with and without any treatments...

Atherosclerosis is a leading cause of death in the United States and worldwide; it emerges as a result of multiple dynamical cell processes including hemodynamics, endothelial damage, innate immunity and sterol biochemistry. Making matters ...

We consider favorite (i.e., most visited) sites of a symmetric persistent random walk on ℤ , a discrete-time process typified by the correlation of its directional history. We show that the cardinality of the set of favorite sites is ...
