By tracking conformational transitions of individual ion channel proteins, single-channel recordings allow the observer to deduce gating mechanisms, as well as estimate rate constants of microscopic gating steps. For most ion channels, gating mechanisms are complex, comprising multiple stable open (O) and closed (C) conformations among which conformational transitions may follow a network of po...

– We analyzed skins and skulls of chevrotains (Moschiola sp., Artiodactyla) from Sri Lanka and India, and found considerable differences within this taxon. Based on the consistency of these differences we concluded that this taxon can be divided into three species: Moschiola indica from southern India, M. meminna from the Dry Zone in Sri Lanka, and M. kathygre n. sp. from Sri Lanka’s Wet Zone. ...

1.1.2 What is randomness? Successive observations, x(n-1), x(n), x(n+1), ... are dependent on one another • If x(n) can be predicted exactly from the previous samples then the time-series signal is deterministic • If x(n) cannot be predicted exactly from the previous samples the time-series signal is random or stochastic • If x(n) is independent from previous samples then the time-series signal...

Activation of presynaptic cAMP-dependent protein kinase A (PKA) triggers presynaptic long-term plasticity in synapses such as cerebellar parallel fiber and hippocampal mossy fiber synapses. RIM1alpha, a large multidomain protein that forms a scaffold at the presynaptic active zone, is essential for presynaptic long-term plasticity in these synapses and is phosphorylated by PKA at serine-413. Pr...
