Is the Increased Transmissibility of SARS-CoV-2 Variants Driven by within or Outside-Host Processes?
Publication Type: Academic Journal
Source(s): Mathematics (2227-7390). Oct2022, Vol. 10 Issue 19, p3422. 17p.
Abstract: Understanding the factors that increase the transmissibility of the recently emerging variants of SARS-CoV-2 can aid in mitigating the COVID-19 pandemic. Enhanced transmissibility could result from genetic variations that improve how the virus operates...
Explosivity and Time-Varying Granger Causality: Evidence from the Bubble Contagion Effect of COVID-19-Induced Uncertainty on Manufacturing Job Postings in the United States.
Publication Type: Academic Journal
Source(s): Mathematics (2227-7390). Dec2022, Vol. 10 Issue 24, p4780. 17p.
Abstract: This study evaluates the explosive behavior and Granger causality episodes in manufacturing job postings in the United States (JOBPUS) and COVID-19-induced uncertainty (COVIDEMV). This study applied the novel unit root tests with explosive behavior, an...
Advancing COVID-19 Understanding: Simulating Omicron Variant Spread Using Fractional-Order Models and Haar Wavelet Collocation.
Publication Type: Academic Journal
Source(s): Mathematics (2227-7390). Apr2023, Vol. 11 Issue 8, p1925. 30p.
Abstract: This study presents a novel approach for simulating the spread of the Omicron variant of the SARS-CoV-2 virus using fractional-order COVID-19 models and the Haar wavelet collocation method. The proposed model considers various factors that affect virus...
Multi-Agent Evolutionary Game Analysis of Group Panic Buying in China during the COVID-19 Pandemic.
Publication Type: Academic Journal
Source(s): Mathematics (2227-7390). Jul2023, Vol. 11 Issue 13, p3006. 24p.
Abstract: With the global outbreak of COVID-19, the panic-buying incidents triggered by the variants of the Omicron strain have severely affected the normal social order. This paper considers the complex interest game and interactive relationship among multiple ...

Stability and Numerical Solutions of Second Wave Mathematical Modeling on COVID-19 and Omicron Outbreak Strategy of Pandemic: Analytical and Error Analysis of Approximate Series Solutions by Using HPM.
Publication Type: Academic Journal
Source(s): Mathematics (2227-7390). Feb2022, Vol. 10 Issue 3, p343. 1p.
Abstract: This paper deals with the mathematical modeling of the second wave of COVID-19 and verifies the current Omicron variant pandemic data in India. We also we discussed such as uniformly bounded of the system, Equilibrium analysis and basic reproduction nu...
A (2+1)-Dimensional Fractional-Order Epidemic Model with Pulse Jumps for Omicron COVID-19 Transmission and Its Numerical Simulation.
Publication Type: Academic Journal
Source(s): Mathematics (2227-7390). Jul2022, Vol. 10 Issue 14, pN.PAG-N.PAG. 14p.
Abstract: In this paper, we would like to propose a (2+1)-dimensional fractional-order epidemic model with pulse jumps to describe the spread of the Omicron variant of COVID-19. The problem of identifying the involved parameters in the proposed model is reduced ...
Fractional-Order SEIRD Model for Global COVID-19 Outbreak.
Publication Type: Academic Journal
