A New Class of Generalized Fractal and Fractal-Fractional Derivatives with Non-Singular Kernels
Fractal and Fractional, 2023 The present paper introduces a new class of generalized differential and integral operators. This class includes and generalizes a large number of definitions of fractal-fractional derivatives and integral operators used to model the complex dynamics of ...

Information fractal dimension of mass function [PDF]
Fractals, 2021 Fractal plays an important role in nonlinear science. The most important parameter to model fractal is fractal dimension. Existing information dimension can calculate the dimension of probability distribution.

Fractal Analysis of Particle Distribution and Scale Effect in a Soil–Rock Mixture
Fractal and Fractional, 2022 A soil–rock mixture (SRM) is a type of heterogeneous geomaterial, and the particle distribution of SRM can be described by fractal theory. At present, it is difficult to quantify the fractal dimension of a particle size distribution and understand the ...

Homotopy Perturbation Method for the Fractal Toda Oscillator
Fractal and Fractional, 2021 The fractal Toda oscillator with an exponentially nonlinear term is extremely difficult to solve; Elias-Zuniga et al. (2020) suggested the equivalent power-form method.

Vaccines Alone Cannot Slow the Evolution of SARS-CoV-2
Vaccines, 2023 The rapid emergence of immune-evading viral variants of SARS-CoV-2 calls into question the practicality of a vaccine-only public-health strategy for managing the ongoing COVID-19 pandemic. It has been suggested that widespread vaccination is necessary to

Convergence and density results for parabolic quasi-linear Venttsel’ problems in fractal domains [PDF]
, 2019 In this paper we study a quasi-linear evolution equation with nonlinear dynamical boundary conditions in a three dimensional fractal cylindrical domain Q, whose lateral boundary is a fractal surface S.
