Dynamical Behavior of a Fractional Order Model for Within-Host SARS-CoV-2
Mathematics, 2022 The prime objective of the current study is to propose a novel mathematical framework under the fractional-order derivative, which describes the complex within-host behavior of SARS-CoV-2 by taking into account the effects of memory and carrier.

On Λ-Fractional Wave Propagation in Solids
Mathematics, 2023 Wave propagation in solids is discussed, based upon inherently non-local Λ-fractional analysis. Following the governing equations of Λ-fractional continuum mechanics, the Λ-fractional wave equations are derived.

How did climate drive the historical distribution of relict plants: a case study on Metasequoia using deep-time ecological niche modelling [PDF]
PeerJRelict plants are those that once had a wide distribution but are now restricted to small areas. It is important to study the process of their distribution in the geological past to better understand the climatic factors that shape their current ...
