(m,�n)-Paranormal Composition Operators
(Springer, 2022-03-22)In this paper, we prove some characterizations for the class of (m,�n)-paranormal operators acting on the complex Hilbert space H. The class of (m,�n)-paranormal operators is characterized in terms of the Radon�Nikodym ... -
A malaria model with Caputo-Fabrizio and Atangana-Baleanu derivatives
(World Scientific, 2020-11-02)In this paper, we study two fractional models in the Caputo-Fabrizio sense and Atangana-Baleanu sense, in which the effects of malaria infection on mosquito biting behavior and attractiveness of humans are considered. Using ... -
Mathematical structure of mosaic disease using microbial biostimulants via Caputo and Atangana�Baleanu derivatives
(Elsevier B.V., 2021-04-21)In this research collection, we analysed two different fractional non-linear mathematical models of a well-known mosaic epidemic of plants, which is underlying by begomoviruses and is distributed to plants by whitefly. We ... -
A mathematical study of a tuberculosis model with fractional derivatives
(World Scientific, 2021-02-04)In this work, we use a Predictor-Corrector method to implement and derive an iterative solution of an existing Tuberculosis (TB) model with two fractional derivatives, namely, Caputo-Fabrizio fractional derivative and the ... -
Mild solutions of coupled hybrid fractional order system with caputo-hadamard derivatives
(World Scientific, 2021-05-15)This paper is devoted to prove the existence of mild solutions of coupled hybrid fractional order system with Caputo-Hadamard derivatives using Dhage fixed point theorem in Banach algebras. In order to confirm the applicability ... -
Modeling Bivariate Data Using Linear Exponential and Weibull Distributions as Marginals

Moderation effects of serotype on dengue severity across pregnancy status in Mexico
(BioMed Central Ltd, 2023-03-26)Background: Pregnancy increases a woman�s risk of severe dengue. To the best of our knowledge, the moderation effect of the dengue serotype among pregnant women has not been studied in Mexico. This study explores how ... -
Monkeypox Viral Transmission Dynamics And Fractional-Order Modeling With Vaccination Intervention
(World Scientific, 2023-03-20)A current outbreak of the monkeypox viral infection, which started in Nigeria, has spread to other areas of the globe. This affects over 28 nations, including the United Kingdom and the United States. The monkeypox virus ... -
