In this report, I present a simple model using springs to conceptualize the relationship between ionic conductances across a cellular membrane and their effect on membrane potential. The equation describing the relationships linking membrane potential, ionic equilibrium potential, and ionic conductance is of similar form to that describing the force generated by a spring as a function of its di...

The ill-posedness arises from the influence of transition on the upstream boundary layer via the potential flow and the viscous displacement effect. When transition begins at xtr, both δ and H first decrease rapidly from their laminar values. The transition region therefore looks like a sink to the potential flow. This effective sink accelerates the upstream potential flow ue(x) towards the tra...

BACKGROUND Mortality displacement (or "harvesting") has been identified as a key issue in the assessment of the temperature-mortality relationship. However, only a few studies have addressed the "harvesting" issue and findings have not been consistent. OBJECTIVES We examined the potential impact of both short- and long-term harvesting effects on heat-related deaths in Brisbane, Australia. M...
