In this paper, we construct the SV1V2EIR model to reveal the impact of two-dose vaccination
on COVID-19 by using Caputo fractional derivative. The feasibility region of the proposed …

In this paper, we study a Caputo–Fabrizio fractional order epidemiological model for the
transmission dynamism of the severe acute respiratory syndrome coronavirus 2 pandemic …

In this paper, a non-singular SIR model with the Mittag-Leffler law is proposed. The
nonlinear Beddington-DeAngelis infection rate and Holling type II treatment rate are used …

In this work, we present a model that uses the fractional order Caputo derivative for the novel
Coronavirus disease 2019 (COVID-19) with different hospitalization strategies for severe …

This study examines the dynamics of COVID-19 variants using a Caputo–Fabrizio fractional
order model. The reproduction ratio R 0 and equilibrium solutions are determined. The …

Fractal-fractional derivatives, which are still rather new, are frequently used to look into the
complexities of an issue. Today, tumors are a prevalent and difficult-to-treat condition. The …

In this paper, we propose a physics-informed neural network-based scheme to solve time-
varying impulsive fractional differential equations without any labeled data. At first, the …

The SARS-CoV-2 pandemic is an urgent problem with unpredictable properties and is
widespread worldwide through human interactions. This work aims to use Caputo-Fabrizio …

The mathematical modeling of new emerging infectious diseases gaining high attention from
the researcher's around the world. We formulate a mathematical model with the statistical …

This paper is focused on the design of optimal control strategies for COVID-19 and the
model containing susceptible individuals with awareness of protection and susceptible …
