These articles focus on the question of the relative significance of periodic and chaotic dynamics in biological systems, and their connection with pathological and non-pathological conditions. Among the many topics are polypeptide hormones and receptors, periodic forcing of a biochemical system, intercellular communication mechanisms, forced oscillations, pancreatic B-cell factors, biological information processing, ecology and epidemiology, and the mathematical implications of these and other factors.
