Optimal strategies for controlling the outbreak of COVID-19: Reducing its cost and duration
Nonautonomous Dynamical Systems, 2023 Social distancing plays an essential role in controlling the spread of an epidemic, but changing the behavior of individuals regarding social distancing is costly.

Bifurcation-based parameter tuning in a model of the GnRH pulse and surge generator [PDF]
, 2008 We investigate a model of the GnRH pulse and surge generator, with the definite aim of constraining the model GnRH output with respect to a physiologically relevant list of specifications. The alternating pulse and surge pattern of secretion results from

The Dynamics of an HIV/AIDS Model with Screened Disease Carriers
Computational and Mathematical Methods in Medicine, Volume 10, Issue 4, Page 287-305, 2009., 2009 The presence of carriers usually complicates the dynamics and prevention of a disease. They are not recognized as disease cases themselves unless they are screened and they usually spread the infection without them being aware. We argue that this has been one of the major causes of the spread of human immunodeficiency virus (HIV).

Mathematical analysis of a MERS-Cov coronavirus model
Demonstratio Mathematica, 2022 In this study, we have proposed a mathematical model to describe the dynamics of the spread of Middle East Respiratory Syndrome disease. The model consists of six-coupled ordinary differential equations.

Computational and Mathematical Methods in Medicine, Volume 9, Issue 2, Page 105-119, 2008., 2008 We invented a standardization method to measure the cup′s anteversion after total hip arthroplasty without the influence of patient′s position. We measured 68 radiographs of 10 patients after total hip replacement (THR) and calculated the error of each measurement, defined as the difference with the average of the same measuring method on the same ...

Modelling Immune Response and Drug Therapy in Human Malaria Infection
Computational and Mathematical Methods in Medicine, Volume 9, Issue 2, Page 143-163, 2008., 2008 A new intra‐host model of malaria that describes the dynamics of the blood stages of the parasite and its interaction with red blood cells and immune effectors is proposed. Local and global stability of the disease free equilibrium are investigated. Conditions for existence and uniqueness of the endemic equilibrium are derived.

Computational and Mathematical Biophysics, 2023 This article presents a cost-effective optimal control analysis of interventions applied to a S2EI2RS type deterministic compartmental model of COVID-19, considering community awareness and immunity loss. We introduce two time-dependent controls, namely,

A Stochastic Model of Icosahedral Capsid Growth
Computational and Mathematical Methods in Medicine, Volume 6, Issue 2, Page 95-97, 2005., 2005 A model of growth of icosahedral capsids is proposed. It is similar to the stochastic model of fullerene growth, but takes into account variations in the composition of pentamers and hexamers that are responsible for the final capsid size. We show that the observed high yield of capsid production implies a high level of self‐organization of the ...

Effect of randomly fluctuating environment on autotroph‐herbivore model system
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 68, Page 3703-3716, 2004., 2004 First we deal with a brief introduction of the autotroph‐herbivore model system along with deterministic analysis of local stability, bifurcation behavior, and persistence of the populations. The second part consists of the stochastic formulation of the model system to incorporate the effect of environmental fluctuation and then analysis of ...
