A mathematical model to study the spread of COVID-19 and its control in India

open access: yesComputational and Mathematical Biophysics, 2023
In this article, a nonlinear mathematical model is proposed and analyzed to study the spread of coronavirus disease (COVID-19) and its control. Due to sudden emergence of a peculiar kind of infection, no vaccines were available, and therefore, the ...

Analysis and estimation of the COVID-19 pandemic by modified homotopy perturbation method

open access: yesApplied Mathematics in Science and Engineering, 2023
The Bernoulli equation is useful to assess the motility and recovery rate with respect to time in order to measure the COVID-19 outbreak. The homotopy perturbation method was applied in the current article to compute the Bernoulli equation.

A developmentally-stable pattern of premorbid schizoid-schizotypal features predicts psychotic transition from the clinical high-risk for psychosis state

open access: yesComprehensive Psychiatry, 2019
Background: Despite the extensive research performed on prediction of psychosis from a Clinical High Risk for Psychosis state (CHR-P), the positive predictive value of the CHR-P designation remains unsatisfactory and further models including additional ...

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 ...

Derangement model of ligand-receptor binding

open access: yesComputational and Mathematical Biophysics, 2022
We introduce a derangement model of ligand-receptor binding that allows us to quantitatively frame the question “How can ligands seek out and bind to their optimal receptor sites in a sea of other competing ligands and suboptimal receptor sites?” To ...

Unconditionally positive NSFD and classical finite difference schemes for biofilm formation on medical implant using Allen-Cahn equation

open access: yesDemonstratio Mathematica, 2022
The study of biofilm formation is becoming increasingly important. Microbes that produce biofilms have complicated impact on medical implants.

Natural Killer Cells for Immunotherapy – Advantages of the NK-92 Cell Line over Blood NK Cells

open access: yesFrontiers in Immunology, 2016
Natural killer (NK) cells are potent cytotoxic effector cells for cancer therapy and potentially for severe viral infections. However, there are technical challenges to obtain sufficient numbers of functionally active NK cells from a patient’s blood ...

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.

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 ...

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.
