High peak power, tunable, narrowband terahertz emitters are becoming sought after given their portability, efficiency, and ability to be deployed in the field for industrial, medical, military applications. The use of accelerator systems producing THz frequencies via Cherenkov radiation, generated by passing an electron beam through a slow-wave wakefield structure, is promising method meet futu...

A new micro T-tube, 0.6 mm in outer diameter, has been constructed. Use of this tube has allowed 1-mm common carotid artery (CCA) bypass ofr periods of time up to 22 minutes. After bypass, scanning electron microscopic observation of sutured CCA endothelium showed widespread destruction, scattered attached platelets and other formed blood elements, as well as microthrombi both at suture lines a...

Rectifier neurons differ from standard ones only in that the sigmoid activation function is replaced by the rectifier function, max(0, x). Several recent studies suggest that rectifier units may be more suitable building units for deep nets. For example, we found that with deep rectifier networks one can attain a similar speech recognition performance than that with sigmoid nets, but without th...

An approach recently introduced to correct the power factor of single-phase and three-phase diode rectifiers is extended to single-phase line-frequency phase-controlled rectifiers. First of all, the conventional circuit of the thyristor based rectifier is proposed to be modified in order to make possible the control of the DC-voltage mean value also in presence of a fully resistive behaviour of...
