A technique to enhance the response of Brillouin distributed sensors is proposed and experimentally validated. The method consists in creating a multi-frequency pump pulse interacting with a multi-frequency continuous-wave probe. The power of each pu

Sensitive optical hydrophone is a key component for the design of compact fully optical acoustic arrays and one major issue about this kind of sensors is their sensitivity to hydrostatic pressure and temperature. We present in this paper a compact hy

Several L-enantiomers of nucleoside analogues were stereospecifically synthesized by a multi-step reaction from L-xylose and their antiviral properties were examined in vitro. Two of them, namely β-L-2′,3,′-dideoxycytidine (β-L-ddC) and its 5-f

A series of adenine nucleoside derivatives, most of them prepared for the first time, have been evaluated as substrates or inhibitors of adenosine deaminase. The best inhibitory results were obtained with the 3′, 5′-di-O-benzoyl esters of 9-β-D-

Starting from D-ribose, the title compound 8 was prepared by a multistep approach in 6.6% overall yield. In none of the biological assays in which it was evaluated did α-guanosine demonstrate appreciable activity.

In TDMA communications systems using all feedforward synchronization techniques, the quality of data decoding strictly depends on the estimation accuracy of the synchronization parameters (timing, carrier phase/frequency and preamble detection) extra

In burst transmission, carrier recovery is a critical point for synchronization systems. With a feedforward carrier phase recovery algorithm, a small frequency offset can significantly increase the cycle slip rate and then the phase error variance. T

In burst transmission, carrier recovery is a crucial point for synchronization systems. Indeed, an imprecise frequency estimation can cause cycle slips. An unbiased feedforward frequency estimator, for M-PSK modulated signals, in the non data aided m
