Periodic solutions of nonautonomous Mackey-type systems with delays [pre-print]
(Mathematical Research Publishers, 2013)
Nonautonomous systems of delay differential equations, that model classical Mackey-type hematopoietic stem cell dynamics and Mackey-type circuit systems, are under study. Explicit sufficient and necessary conditions for ...
Stability of Hahnfeldt angiogenesis models with time lags [post-print]
Mathematical models of angiogenesis, pioneered by Hahnfeldt, are under study. To enrich the dynamics of three models, we introduced biologically motivated time-varying delays. All models under study belong to a special ...
Existence of periodic solutions in the modified Wheldon model of CML
(Department of Mathematics, Texas State University, 2013)
The Wheldon model (1975) of a chronic myelogenous leukemia (CML) dynamics is modified and enriched by introduction of a time-varying microenvironment and time-dependent drug efficacies. The resulting model is a special ...
