Sensory-evoked signal flow, at cellular and network levels, is primarily determined by the synaptic wiring of the underlying neuronal circuitry. Measurements of synaptic innervation, connection probabilities and subcellular organization of synaptic inputs are thus among the most active fields of research in contemporary neuroscience. Methods to measure these quantities range from electrophysiol...

The primary event occurring during the E-to-Z photoisomerization reaction of retinal protonated Schiff base (rPSB) is single-to-double bond inversion. In this work we examine nuclear dynamics that occurs when initial excited state a superposition S1 and S2 electronic states might be created in laser experiment. dominated by double inversion parallel to derivative coupling vector S2. Thus, molec...

Polysulfide shuttle effect, causing extremely low Coulombic efficiency and cycling stability, is one of the toughest challenges hindering development practical lithium sulfur batteries (LSBs). Introducing catalytic nanostructures to stabilize otherwise soluble polysulfides promote their conversion solids has been proved be an effective strategy in attacking this problem, but heavy mass catalyst...

The ability of the present semiempirical quantum mechanics methods are surveyed for reproducing the transannular interaction in the bifunctional N-phenyl-5-azocanones. The AM1 method is the best with the order of reliability being Am1, PM3, MNDO and MINDO/3. AM1 calculations were then carried out for quantification of transannular interaction. The n(o) ionization potential has be...
