The majority of medical accelerators for radiation therapy use frequencies in the S-band range. Having a compact accelerator allows for a wide range of treatments. The size and weight of the accelerator are substantially reduced if a higher frequency is used. X-band frequencies are suitable for such applications. X-band accelerator technology has been used in high-energy, as well as, industrial...

pyridostigmine bromide (pb) is a reversible cholinesterase inhibitor. the aim of this study was to determine the effect of orally administration of single dose sustained-released tablet of pyridostigmine bromide (pbsr) on the frequency domain indices of heart rate variability (hrv). thirty-two healthy young men were participated in this study. they were divided into 2 groups; the pyridostigmine...

In multi-band optical networks, a band-switchable cross-connect (MB-OXC), which enables not only the output port but also wavelength band of input signals to be switched, can significantly increase accommodated traffic volume. An all-optical inter-band converter (AO-WC) is key device achieve MB-OXC and required have little signal degradation even when pass through it many times. this paper, we ...
