Electrical and chemical synapses exist within the same networks of inhibitory cells, and each kind of synapse is known to be able to foster synchrony among oscillating neurons. Using numerical and analytical techniques, we show here that the electrical and inhibitory coupling play different roles in the synchronization of rhythms in inhibitory networks. The parameter range chosen is motivated b...
When dissociated neurons from the mollusc, Aplysia californica, are placed in primary cell culture, they form electrical synapses in a specific, yet alterable, manner. Pairs of neurons from the same ganglion ("homoganglionic" pairs) form electrical synapses with high coupling coefficients. This is due to relatively high macroscopic junctional conductance as determined directly by voltage clampi...
The Icicle have the thickness-waves along themselves with proper wave-length. We show such waves can be introduced by the resonance between the fluctuation of solid surface and the ones of surface of water flow on the icicle.
Oligoynes are archetypical molecular wires due to their 1-D chain of conjugated carbon atoms and ability to transmit charge over long distances by coherent tunneling. However, the stability of the oligoyne can be an issue. Here we address this problem by two stabilization methods, namely sterically shielding endgroups, and rotaxination to produce an insulated molecular wire. We demonstrate the ...
We investigate Aharonov-Bohm oscillations of the electrical current through a strongly correlated quantum dot embedded in an arbitrary scattering geometry in the linear and nonlinear regime. We also study the temperature and ux dependence of the thermopower S and nd that it changes sign with temperature. At the temperature where S(T0) = 0, the thermal properties are strongly ux dependent as com...
Electrical conductance measurements are being used experimentally to diagnose caries. Current equipment, e.g. the electronic caries monitor (ECM), uses a probe to scan occlusal fissures. For full-mouth examination this method is rather time-consuming. A method with which only one measurement is needed for an entire (occlusal) surface would be preferable. However, the enlargement of the area bei...
