Motivated by a recent experiment [Keizer et al., Nature (London) 439, 825 (2006)], we study the Josephson effect in superconductor/diffusive half metal/superconductor junctions using the recursive Green function method. The spin-flip scattering at the junction interfaces opens the Josephson channel of the odd-frequency spin-triplet Cooper pairs. As a consequence, the local density of states in ...

Mathematical models of cell electrical activity typically consist of a current balance equation, channel activation (or inactivation) variables and concentrations of regulatory agents. These models can be thought of as nonlinear filters whose input is some applied current I (possibly zero) and output is a membrane potential V. A natural question to ask is if the applied current I can be deduced...

Activated phospholipase C (PLC*) generates 1,4,5-triphosphate (IP3) and diacylglycerol (DAG) from phosphatidyl inositol (PIP2). The DAG remains in the plasma membrane and co-activates conventional protein kinase C (PKC) with Ca2+. We have developed a mathematical model for the activation of the Ca2+-dependent PKC and its negative feedback on phospholipase C (PLC) and coupled it to the De Young-...

Many models of bursting electrical activity (BEA) in pancreatic β-cells have been proposed. BEA is characterized by a periodic oscillation of the membrane potential consisting of a silent phase during which the membrane potential is varying slowly and an active phase during which the membrane potential is undergoing rapid oscillations. An important experimental observation of BEA is a correlati...
