2007 article

Comparison between stochastic and deterministic selection-mutation models

Ackleh, A. S., Hu, S., Ackleh, A. S., & Hu, S. (2007, January 1). Mathematical Biosciences & Engineering.

By: A. Ackleh*, S. Hu n, A. Ackleh* & S. Hu n

author keywords: selection-mutation models; competitive exclusion; coexistence; stochastic differential equations
MeSH headings : Algorithms; Animals; Biological Evolution; Computer Simulation; Genetic Variation / genetics; Genetics, Population; Humans; Models, Genetic; Models, Statistical; Mutation / genetics; Selection, Genetic; Stochastic Processes
topics (OpenAlex): Evolution and Genetic Dynamics; Mathematical and Theoretical Epidemiology and Ecology Models; Stochastic processes and statistical mechanics
TL;DR: If the differences in the growth-to-mortality ratios are small in the pure selection case, it cannot be determined a priori which subpopulation will have the highest probability of surviving and winning the competition. (via Semantic Scholar)

2006 article

A structured erythropoiesis model with nonlinear cell maturation velocity and hormone decay rate

Ackleh, A. S., Deng, K., Ito, K., & Thibodeaux, J. (2006, August 21). Mathematical Biosciences.

By: A. Ackleh*, K. Deng*, K. Ito n & J. Thibodeaux*

author keywords: erythropoiesis; structured model; finite difference approximation; existence-uniqueness; behavior of solutions
MeSH headings : Cell Differentiation / physiology; Computer Simulation; Erythroid Precursor Cells / physiology; Erythropoiesis / physiology; Erythropoietin / physiology; Humans; Models, Biological
topics (OpenAlex): Erythrocyte Function and Pathophysiology; Blood properties and coagulation; Blood groups and transfusion
TL;DR: A quasilinear structured model that describes the regulation of erythropoiesis, the process in which red blood cells are developed shows that a velocity of precursor cells maturation rate and a decay rate of the hormone which is an increasing function of the number of precursor Cells have a stabilizing effect on the dynamics of the model.
