Using a single-channel active Raman gain medium, we show a 220±20 ns advance time for an optical pulse of FWHM=15.4 s propagating through a 10 cm medium, a lead
Six different tetracalcium phosphate products were synthesized by solid state reaction at high temperature by varying the overall calcium to phosphate ratio of
A flow-level Markov model for fair bandwidth sharing with packet retransmissions under random flow arrivals/departures is proposed and discussed. Fluctuations
Reliable state detection plays a central role in quantum-limited metrology and quantum information processing. For example, in quantum computation low error
