Fractional Calculus as a Simple Tool for Modeling and Analysis of Long Memory Process in Industry
Mathematics, 2019 This paper deals with the application of the fractional calculus as a tool for mathematical modeling and analysis of real processes, so called fractional-order processes. It is well-known that most real industrial processes are fractional-order ones. The

Fractional Differential and Integrating Equations by Numerical Solution
INTERNATIONAL JOURNAL OF MATHEMATICS AND COMPUTER RESEARCH, 2022 The main objective of this paper is to investigate a new fractional mathematical model that includes a nonsingular derivative factor. The basic properties of the new model including non-negative, finite solution, numerical simulations are shown, and some discussions from mathematical perspectives are given. Then, the optimal control problem for the new

Axioms, 2020 We propose two efficient numerical approaches for solving variable-order fractional optimal control-affine problems. The variable-order fractional derivative is considered in the Caputo sense, which together with the Riemann–Liouville integral operator ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Discrete Laplacian Operator and Its Applications in Signal Processing
IEEE Access, 2020 Fractional calculus has increased in popularity in recent years, as the number of its applications in different fields has increased. Compared to the traditional operations in calculus (integration and differentiation) which are uniquely defined, the ...

A new scheme for the solution of the nonlinear Caputo–Hadamard fractional differential equations
Alexandria Engineering JournalThis paper introduces a numerical approach by generalizing Legendre wavelets for solving nonlinear Caputo–Hadamard fractional differential equations. The methodology involves the extension of classical Legendre wavelets, namely the generalized Legendre ...
