Purpose The variational principle views a complex problem in an energy way, it gives good
physical understanding of an iteration method, and the variational-based numerical methods …

A tumor is most dangerous disease of medical science which is a mass or lumps of tissue
that's formed by an accumulation of abnormal cells. A famous fractional tumor-immune …

The parasitoid is a broad evolutionary association of hymenopteran insects which are well‐
known as biological control agents. Parasites are different from predators because parasites …

This paper proposes a new definition of fractional derivative with non-singular kernel in the
sense of Caputo which generalizes various forms existing in the literature. Furthermore, the …

In the Nidovirales order of the Coronaviridae family, where the coronavirus (crown‐like
spikes on the surface of the virus) causing severe infections like acute lung injury and acute …

A fractional compartmental mathematical model for the spread of the COVID-19 disease is
proposed. Special focus has been done on the transmissibility of super-spreaders …

The range of effectiveness of the novel corona virus, known as COVID-19, has been
continuously spread worldwide with the severity of associated disease and effective …

At a microgravity condition, a spaceflight might be subject to a microgravity‐induced
vibration. There is no theory so far to study the effect of microgravity on the vibration …

Abstract The Lotka‐Volterra model is a very famous model and frequently used to describe
the dynamics of ecological systems in which two species interact, one a predator and one its …

This paper presents a thorough study of a time-dependent nonlinear Schrödinger (NLS)
differential equation with a time-fractional derivative. The fractional time complex transform is …
