A mathematical description of biological clocks

Biosystems, 1967
Abstract The implications of a concise mathematical formulation of the effect of light pulses on circadian rhythms are presented and discussed. The description is based on a model originally proposed by Pittendrigh.

Mathematics in the biological sciences

International Studies in the Philosophy of Science, 1992
Abstract Although mathematical descriptions of the dynamics of system are widely employed in the physical sciences, they are employed infrequently in the biological sciences. The explanation for this usually appeals to the complexity of biological systems.

A mathematical model of evolution of biological populations

Cybernetics, 1990
Summary: We determine the laws of evolution of closed populations in a self- regulating biogeocenosis. We show that the evolutionary moving force creating new genotypes is the variability of the biotypic effects, whereas the evolutionary factor that regulates (stabilizes) the size of the population is the variability of the biocenotic effects.

BioLogic: A Mathematical Modeling Framework for Immunologists

2009
The immune response to pathogens is a result of complex interactions among many cell types and a large number of molecular processes. As such it poses numerous challenges for modeling, simulation, and analysis. In this work we aim at addressing major issues regarding modeling of large biological systems with a special focus on the immune system.

A mathematical model of biological growth and regression

Biosystems, 1969
Abstract A mathematical model of cell and bacterial growth and regression is presented. The model is, in part, composed of tentative laws of growth and regression. The mathematical solutions of the model were obtained; they indicate the factors which affect various aspects of growth and regression behavior.

Mathematical Description of Biological Structures and Mechanisms

2008 International Conference on Biocomputation, Bioinformatics, and Biomedical Technologies, 2008
A new formalism and approach to describing cellular and molecular processes and structures is introduced, designed to support the creation of knowledge bases of molecular and cellular mechanisms, structures, and states in which all structural information about the entities, at all levels of detail, is represented formally.
