We propose a standardization procedure that provides a convenient, quantitative and reproducible laboratory-based method for measuring the state of polarization (SOP) fluctuations produced by polarization varying devices. This method is based on the

PMD effects impose severe penalties on older fiber plants at 10Gb/s and on virtually all plants at 40Gb/s. An optical compensator can mitigate these penalties, allowing error-free performance without severely limiting the regenerator distances. A rep

Exposure of winter rye leaves grown at 20 degrees C and an irradiance of either 50 or 250 micromol m(-2) s(-1) to high light stress (1600 micromol m(-2) s(-1), 4 h) at 5 degrees C resulted in photoinhibition of PSI measured in vivo as a 34% and 31% d
