Viral infections pose significant threats to public health globally. Understanding the
behavior, transmission, and epidemiology of viruses is essential for develo** strategies to …

This paper aims to model the COVID-19 mortality rates in Italy, Mexico, and the Netherlands,
by specifying an optimal statistical model to analyze the mortality rate of COVID-19. A new …

This study explores the intricacies of the COVID-19 pandemic by employing a four-
compartment model with a fractal-fractional derivative based on Caputo concept. The …

We develop a new mathematical model by including the resistive class together with
quarantine class and use it to investigate the transmission dynamics of the novel corona …

Fractional-order derivative-based modeling is very significant to describe real-world
problems with forecasting and analyze the realistic situation of the proposed model. The aim …

In this article we study a fractional-order mathematical model describing the spread of the
new coronavirus (COVID-19) under the Caputo-Fabrizio sense. Exploiting the approach of …

COVID-19 is caused by the increase of SARS-CoV-2 viral load in the respiratory system.
Epithelial cells in the human lower respiratory tract are the major target area of the SARS …

It is of great curiosity to observe the effects of prevention methods and the magnitudes of the
outbreak including epidemic prediction, at the onset of an epidemic. To deal with COVID-19 …

Abstract Corona-virus disease 2019 (COVID-19) is an infectious disease that has affected
different groups of humankind such as farmers, soldiers, drivers, educators, students …

In this study, we investigate the nonlinear dynamics of solitary waves in saturated
ferromagnetic materials with an external field of zero conductivity. Here, we talk about how …
