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.

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 ...

Outstanding junior investigator program. [Final technical report, 8/1/92-10/31/97] [PDF]

open access: yes, 1999
Much of the authors work over the past five years has been aimed at bridging the gap between the exactly supersymmetric world of string theories and the world that is actually observed. Her report discusses the following subjects: (1) supersymmetry breaking; related work on the mass hierarchy and the relation between supersymmetry and grand unified ...

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 ...

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.

A Separate Higgs? [PDF]

open access: yes, 1992
We investigate the possibility of a multi-Higgs doublet model where the lightest neutral Higgs boson ($h^0$) decouples from the fermion sector. We are partially motivated by the four $\ell^+\ell^-\gamma\gamma$ events with $M_{\gamma\gamma}\simeq60$\,GeV ...

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 ...
