CDMS-2000城市扬尘监测站(beta射线法) 近年来,随着工业化、城市化的快速推进,雾霾天气在我国频发。很多研究发现,扬尘是造成城市颗粒物污染的重要因素。针对城市扬尘问题, 聚光科技结合多年环境空气监测仪器的开发经验, 开发了一款基于beta射线法的扬尘在线监测系统。该系统可全天候24小时在线连续监测颗粒物浓度、噪声、...
-1a patients also had a significantly lower rate of a combined outcome (CDMS or the development of >1 new or enlarging T2 lesions on MRI at 6, 12, or 18 months). Patients were also evaluated separately by baseline brain MRI T2 lesion volume (high or low), as well as the presence or...
安慰剂对照阶段持续 2年,或直到患者发生了临床确诊的多发性硬化(CDMS),以更早者计。在安慰剂对照阶段之后,患者进入了一个预先计划的倍泰龙随访阶段,通过比较最初随机接受倍泰龙(“立即治疗组”)或安慰剂(“延迟治疗组”)的患者,以评估立即倍泰龙治疗和延迟开始倍泰龙治疗的影响。初始治疗分配对患者和研究者保持...
The dashed curves assume a recoil energy window between 10 − 100 keV for CDMS and between 35 − 100 keV for Argon, while the solid curves show the large increase in sensitivity if a window of 0 − 100...Arisaka K et al (2009) XAX: a multi-ton, multi-target detection system ...
We report on thin-film processing improvements in the fabrication of superconducting quasiparticle-trap-assisted electrothermal-feedback transition-edge sensors (QETs) used in the design of Cryogenic Dark Matter Search (CDMS) detectors. The work was performed as part of a detector upgrade project ...
