Summary Objective Genetic alterations have been identified in the CACNA1H gene, encoding the CaV3.2 T‐type calcium channel in patients with absence epilepsy, yet the precise mechanisms relating to seizure propagation and spike‐wave‐discharge (S

The thesis here by shows that the extant suspension wire, which is stretched between electric poles to support a variety of communication wires, can be replaced by specially-redesigned cables called OPSW(Composite Suspension Wire with Optical Fiber)

Neural stem cells (NSCs) have mainly been applied to neurodegeneration in some medically intractable neurologic diseases. In this study, we established a novel NSC line and investigated the cytotoxic responses of NSCs to exogenous neurotoxicants, glu

We have designed an extended L-band Erbium-doped fiber amplifier to amplify 1625 nm optical time domain reflectometry signal for a long distance monitoring system. The proposed amplifier has a dual-stage structure without an isolator. Gain improvemen

A two-stage erbium-doped fiber amplifier (EDFA) with a band pass filter is used to get optical pulses of high peak value. The pulse signal has a 32 ㏈ extinction ratio, 125 W peak power and 79 ㎽ pulse off power. A nonlinear optical loop mirror (NO

Nanosecond pulses are efficiently amplified by a two-stage EDFA. The EDFA employs an optical bandpass filter between stages to remove the amplified spontaneous emission of the first EDFA that strongly saturates the gain of the second EDFA. The peak p
