Abstract:

The flow between compartments in physical and biological systems is treated as a special case of a more general theory of transitions between any two distinct sets. Interest is focused on the flow rate from each set, i.e., the rate at which elements from that set appear in the other and on the entry rate from each, i.e., the rate at which elements from the set leave to enter the region not part of either set. In particular, the two flow rates are completely determined by means of explicit expressions for their rates and difference in terms of the two entry rates. An application to biological transport problems extends a result of Dantizig and Pace by demonstrating that for a system of channels each narrow enough to effect a lining-up of particles, counter-gradient flows may result, i.e., flows for which the flow rate is greatest from the compartment with the smallest entry rate.
