This work follows as a response to a problem posed in a previous work (Jeff-Eke, 2015b). Here we propose and explore a probable solution to the posed problem of how well a cellular system can tolerate random changes to the frequency of osmolytes infused into an...

This is a companion to A Gauge model for analysis of Biological systems. Here we reconcile the gauge model with a “real” system, which in this case is a unicellular system. We address effects of infusion of free osmolytes into an intracellular space of interest,...
