High performance computational method for fractional model of solid tumour invasion

open access: yesAin Shams Engineering Journal, 2023
The behaviour of the solid tumour invasion system in the sense of Caputo fractional with time ζ and space x is analyzed by the high performance computational method: q-Homotopy Analysis Transform method (q-HATM).

Numerical solution of a malignant invasion model using some finite difference methods

open access: yesDemonstratio Mathematica, 2023
In this article, one standard and four nonstandard finite difference methods are used to solve a cross-diffusion malignant invasion model. The model consists of a system of nonlinear coupled partial differential equations (PDEs) subject to specified ...

Mathematical model of Ehrlichia chaffeensis transmission dynamics in dogs

open access: yesJournal of Biological Dynamics, 2023
Ehrlichia chaffeensis is a tick-borne disease transmitted by ticks to dogs. Few studies have mathematical modelled such tick-borne disease in dogs, and none have developed models that incorporate different ticks' developmental stages (discrete variable ...

An Experimental Study on Mechanical Modeling of Ceramics Based on Microstructure

open access: yesApplied Sciences, 2015
The actual grinding result of ceramics has not been well predicted by the present mechanical models. No allowance is made for direct effects of materials microstructure and almost all the mechanical models were obtained based on crystalline ceramics.

Modeling, Analysis and Physics Informed Neural Network approaches for studying the dynamics of COVID-19 involving human-human and human-pathogen interaction

open access: yesComputational and Mathematical Biophysics, 2022
In this work, the dynamics of the spread of COVID-19 is considered in the presence of both human-to-human transmission as well as environment-to-human transmission.

Spin-axion coupling [PDF]

open access: yes, 2015
We establish a new covariant phenomenological model, which describes an influence of pseudoscalar (axion) field on spins of test massive particles. The model includes general relativistic equations of particle motion and spin evolution in background ...

Global stability dynamics and sensitivity assessment of COVID-19 with timely-delayed diagnosis in Ghana

open access: yesComputational and Mathematical Biophysics, 2022
In this paper, we study the dynamical effects of timely and delayed diagnosis on the spread of COVID-19 in Ghana during its initial phase by using reported data from March 12 to June 19, 2020. The estimated basic reproduction number, ℛ0, for the proposed
