Regulation of Th1/Th2 cells in asthma development: A mathematical model.
, 2019 Airway exposure levels of lipopolysaccharide (LPS) determine type I versus type II helper T cell induced experimental asthma. While high LPS levels induce Th1-dominant responses, low LPS levels derive Th2 cell induced asthma. The present paper develops a

Mathematical model for pulsed chemotherapy
ITM Web of Conferences, 2015 A pulsed chemotherapeutic treatment model is investigated in this work. We prove the existence of nontrivial periodic solutions by the mean of Lyapunov-Schmidt bifurcation method of a cancer model. In this model we consider the case of application of two

Mathematical Modelling Economy
Bulletin of the South Ural State University. Series "Mathematical Modelling, Programming and Computer Software", 2023 Summary: The article presents an overview of the main methods of economic modelling used in scientific research over the past twenty years. This overview does not claim to cover all areas, methods and models used in scientific research in the field of economics, since it is impossible to do within a single article. We consider mathematical modelling of

A MATHEMATICAL MODEL to aid in the Design and Evaluation of a Sound Navigation and Ranging (SONAR) System [PDF]
, 1969 The literature on relevant parameters used in the model is reviewed. A Rigid Mathematical Model and a Stochastic Model are developed to describe acoustic propagation in the medium. The two models are used to determine bounds on the design parameters

Mathematical model on HIV and nutrition
Journal of Biological Dynamics, 2023 HIV continues to be a major global health issue, having claimed millions of lives in the last few decades. While several empirical studies support the fact that proper nutrition is useful in the fight against HIV, very few studies have focused on ...
