Gain narrowing effect
WebApr 11, 2024 · Compared with people who had no weight change, those with >5% weight gain were more likely to have radiographic progression, and those with >5% weight loss were less likely (odds ratios, 1.29 and 0.69, respectively). Among those with weight gain who had progressive changes, medial joint space narrowing was the dominant finding. WebDec 8, 2011 · hybrid gain media with different spectral properties [5], fiber self-phase modulators [6] and superstructure fiber Bragg grat-ing [7], have been applied in CPA chains to compensate for or alleviate gain narrowing effects.
