1Plasmonics for solid-state lighting: enhanced excitation and directional emission of highly efficient light sources显示文摘Light sources based on reliable and energy-efficient light-emitting diodes (LEDs) are instrumental in the development of solid-statelighting (SSL). Most research efforts in SSL have focused on improving both the intrinsic quantum efficiency (QE) and the stability oflight emitters. For this reason, it is broadly accepted that with the advent of highly efficient (QE close to 1) and stable emitters, thefundamental research phase of SSL is coming to an end. In this study, we demonstrate a very large improvement in SSL emission (above70-fold directional enhancement for p-polarized emission and 60-fold enhancement for unpolarized emission) using nanophotonicstructures. This is attained by coupling emitters with very high QE to collective plasmonic resonances in periodic arrays of aluminumnanoantennas. Our results open a new path for fundamental and applied research in SSL in which plasmonic nanostructures are able tomold the spectral and angular distribution of the emission with unprecedented precision.Gabriel Lozano Davy J Louwers Said RK Rodrı´guez Shunsuke Murai Olaf TA Jansen Marc A Verschuuren Jaime Gomez Rivas 2013Light(Science & Applications)2013,2,1:8

7测定血清S100蛋白用于诊断克-雅病:前瞻性病例对照研究显示文摘目的:分析克-雅病(Creutzfeldt-Jakob dis-ease,CJD)患者及对照组血清中脑特异性 S100蛋白浓度。设计:前瞻性病例对照研究。研究单位:国家 CJD 监测站。研究对象:224例疑为 CJD 的转诊患者及35例无痴呆的对照病例。主要结果测定:CJD 患者、其他疾病引起的痴呆患者及对照组血清 S100浓度。结果:224例疑为 CJD 的患者中,65例经病理证实确诊;6例有基因突变而肯定诊断;43例很可能患 CJD;36例可能患 CJD;74例患有其他疾病。108例为肯定或很可能 CJD 患者,其血清 S100浓度中位数为395 pg/ml(SD 387 pg/ml)。这明显高于患其他疾病的74例患者(S100浓度中位数为109pg/ml,SDl77pg/ml;P=0.0001)。以213pg/ml为界值,S100测定用于 CJD 诊断的敏感性为77.8%(95%的可信区间为66.8%~85.2%),特异性为81.1%(70.3%~89.3%)。在 Kaplan-Meier 曲线上,不同浓度 S100患者的存活时间差异有显著性(P=0.023)。结论:S100血清浓度测定是一种有价值的工具,在 CJD 的鉴别诊断中,较测定脑脊液更有价值。尚需更多的研究以确定连续测定是否有助于提高此病的诊断准确性。Markus Otto Jens Wiltfang Ekkehard Schtz Ingo Zerr Anke Otto Annette Pfahlberg Olaf Gefeller Manfred Uhr Armin Giese Thomas Weber Hans A Kretzschmar Sigrid Poser 张星虎 1998英国医学杂志中文版1998,0,1:1
