Prostate cancer is relatively common cancer occurring in males. Radical prostatectomy (RP) is the most effective treatment for a localized tumor but erectile dysfunction (ED) is common complication, even when bilateral nerve-sparing RP (BNSRP) is performed. Clinical trials have shown varied effectiveness of phosphodiesterase type-5 inhibitors (PDE5-Is) for… (More)
The nonlinear transmission and phase noise tolerance performance of three different 8-ary constellations (8PSK, star-shaped 8QAM and circular 8QAM) in coherent optical communication systems are investigated with the improved Viterbi-Viterbi algorithms for carrier phase estimation and radius-directed linear Kalman filter for polarization de-multiplexing.
OBJECTIVE To investigate the quantity and distribution of motor fiber of rat's C7 nerve root. METHODS Motor fiber quantity and section area in the main nerves of the upper extremity and the fascicles of C7 in 30 SD rats were analyzed. RESULTS Fascicles and certain amount (207) of motor fibers from the anterior division of C7 were distributed to… (More)
