Visit-to-visit blood pressure (BP) variability is an important predictor of stroke. However, which antihypertensive drug combination is better at reducing visit-to-visit BP variability and therefore at reducing stroke incidence remains uncertain. We have previously reported that the dihydropyridine calcium channel blocker benidipine combined with a(More)
80-Gbit/s (20 Gbit/s/spl times/4) optical time-division multiplexing is demonstrated using an optical time-division multiplexer based on a hybrid integrated planar lightwave circuit. Each channel signals independently modulated by mixing in semiconductor optical amplifiers.
We have developed a new high-speed 32-channel optical wavelength selector (OWS) with gate drivers using PLC hybrid integration. It has excellent characteristics consisting of a low insertion loss of 2.3 dB, a low cross talk of -46 dB and the error-free optical wavelength selection of 10-Gbit/s optical signal.
