Agrin Converts Electrical Coupling to Chemical Coupling

Science's STKE, 2005
Agrin is a proteoglycan secreted by nerves that is well known for its role in organizing the postsynaptic regions of the neuromuscular junction (NMJ). However, agrin is not limited to nerves that innervate muscle and is a widely expressed protein, suggesting additional roles in synaptic organization in the central and peripheral nervous ...

Electrical coupling in multi-array charge coupled devices

SPIE Proceedings, 2016
Silicon based charge coupled device (CCD) performances have improved immensely over the years. Scientific community across the globe target challenging remote sensing applications with CCD as optical imaging detector. Over the years, both pixel count (from few hundreds to few tens of thousands) and line readout rate (from few kHz to few tens of kHz ...

Electric Coupling in Epileptogenesis

1996
One of the hallmarks of epileptiform activity is neural synchrony. There are several putative mechanisms for creating neural synchrony in a neural network including the chemical synaptic actions of decreased inhibition or increased excitation, extracellular ionic and volume shifts, and changes in electric coupling.

Gravitoelectric-electric coupling via superconductivity

Foundations of Physics Letters, 1993
Recently we demonstrated theoretically that the carriers of quantized angular momentum in superconductors are not the Cooper pairs but the lattice ions, which must execute coherent localized motion consistent with the phenomenon of superconductivity.

Electrical coupling between tunicate heart cells

Life Sciences, 1968
Abstract Heart cells of the tunicate, Chelyosoma , were found to be electrically coupled. The coupling ratio in cells adjacent to the polarized cell was 40%. Electrical current generated by an impulse was observed to spread through an area of local conduction block caused by an overstretched condition.

Electrically Coupled Graded Index Metamaterial

2008 International Workshop on Antenna Technology: Small Antennas and Novel Metamaterials, 2008
We have demonstrated that effective gradient index devices can be fabricated to collimate and steer microwave beams by designing the spatial profile of positive effective permittivity across the slab. Resonant losses in the devices is reduced dramatically by operating at frequency ranges far from the unit cell resonance, and substrate losses is reduced

Performance calculations on electric couplings

Electrical Engineering, 1952
ELECTRIC INDUCTION COUPLINGS often are made with the field inside and the secondary outside exactly like an alternator. The field can be just as readily the outer member if desired. The secondary member often is made as a squirrel cage as in induction motors, and even more often is a simple ring of steel in which eddy currents are induced.

The Basics of Electrical Coupling

1985
Cells are said to be electrically coupled when ionic current injected into one cell passes to the cell’s neighbour. Fig. 1 a illustrates the electrical circuit in the simplest case, when only two cells are present. In a), the cells are simply apposed, and the membranes are assumed to be homogeneous, that is to say no junctions are present.
