Magnetic nerve stimulation is a noninvasive, noncontact means of exciting nerves. Magnetic stimulators generate eddy currents in tissue by producing a high-amplitude, short-duration magnetic pulse from a small coil located near the tissue. A simple circuit can generate the large coil currents necessary for magnetic nerve stimulation. Careful selection of circuit components is necessary to contr...

Compact, high-gain magnetic flux compressors (FCGs) are convenient sources of substantial energy for plasma-physics and electron-beam-physics experiments, but the need for highvoltage, fast-rising pulses is difficult to meet directly with conventional generators. While a variety of novel concepts employing simultaneous, axially-detonated explosive systems are under development, power-conditioni...

In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic ran...

in this article, we have used 36 electricity distribution companies of iran and by using input-oriented dea, we analysis the companies technical efficiency with respect to group frontier and metafrontier following restructuring, then we investigate the factors affecting efficiency. the companies decomposed to two groups in terms of high and low circuit density. for discussing the impact of stru...

The neural substrate subserving magnetoreception and magnetic orientation in mammals is largely unknown. Previous experiments have demonstrated that the processing of magnetic sensory information takes place in the superior colliculus. Here, the effects of magnetic field conditions on neuronal activity in the rodent navigation circuit were assessed by quantifying c-Fos expression. Ansell's mole...

In this paper, a novel approach to achieving the independent control of multiple magnetic microrobots is presented. The approach utilizes a specialized substrate consisting of a fine grid of planar, MEMS-fabricated micro coils of the same size as the microrobots (≤ 500 μm). The coils can be used to generate real magnetic potentials and, therefore, attractive and repulsive forces in the workspac...

With the development of superconducting magnets, the chances of exposure to intense static magnetic fields (SMFs) have increased. Therefore, safety concerns related to magnetic field exposure need to be studied, especially the effects of magnetic field exposure on the central nervous system. Only a limited number of studies prove a direct connection between magnetic fields and electrophysiologi...
