We propose a new mathematical model to investigate the recent outbreak of the coronavirus
disease (COVID-19). The model is studied qualitatively using stability theory of differential …

Environmental factors such as, humidity and temperature pose significant impacts on the
dynamics of hepatitis B virus (HBV). The stochastic modeling has been proved to be a …

HIV/AIDS and COVID-19 co-infection is a common global health and socio-economic
problem. In this paper, a mathematical model for the transmission dynamics of HIV/AIDS and …

In recent years, the availability of advanced computational techniques has led to a growing
emphasis on fractional-order derivatives. This development has enabled researchers to …

Students' day-to-day activities can be influenced by internal and external factors that can
cause academic turbulence. These factors vehemently impart to the setback of bad …

ABSTRACT The novel Coronavirus (COVID-19) infection has become a global public health
issue, and it has been a cause for morbidity and mortality of more people throughout the …

In this study, we analyse the behaviour of the coinfection of the HIV-TB model using a
piecewise operator in the classical-Caputo sense. For the aforementioned disease model …

Distinct fractional models of falling object with linear and quadratic air resistive forces are
explored under Caputo fractional derivative. Analytical solutions to each model are extracted …

HIV/AIDS and pneumonia coinfection have imposed a major socioeconomic and health
burden throughout the world, especially in the develo** countries. In this study, we …

HIV/AIDS-COVID-19 co-infection is a major public health concern especially in develo**
countries of the world. This paper presents HIV/AIDS-COVID-19 co-infection to investigate …
