1应用双能CT显示泌尿系统结石的特征:低剂量扫描方案的体外和在体评估显示文摘评价双能CT评估泌尿系统结石的低剂量方案的辐射剂量和效能。双能CT低剂量肾结石检查方案(140kV,46mAs:80kV,210mas)衍生于我院检查肾结石的单能CT检查方案(120kV,75mAs)。采用上述2种检查方案分别对配置热释光剂量仪的Alderson—Rando模型进行扫描。计算有效剂量。51例怀疑或确诊的泌尿系结石病人行双能CT扫描。检测到结石后用专用软件包进行双能分析,将结果与术后取出结石的化学分析进行对比。双能扫描时,C.

2Increased liver stiffness in alcoholic liver disease:Differentiating fibrosis from steatohepatitis显示文摘AIM:To test if inflammation also interferes with liver stiffness (LS) assessment in alcoholic liver disease (ALD) and to provide a clinical algorithm for reliable fibrosis assessment in ALD by FibroScan (FS).METHODS:We first performed sequential LS analysis before and after normalization of serum transaminases in a learning cohort of 50 patients with ALD admitted for alcohol detoxification. LS decreased in almost all patients within a mean observation interval of 5.3 d. Six patients (12%) would have been misdiagnosed with F3and F4 fibrosis but LS decreased below critical cut-off values of 8 and 12.5 kPa after normalization of trans-aminases. RESULTS:Of the serum transaminases,the decrease in LS correlated best with the decrease in glutamic oxaloacetic transaminase (GOT). No significant chang-es in LS were observed below GOT levels of 100 U/L. After establishing the association between LS and GOT levels,we applied the rule of GOT < 100 U/L for reliable LS assessment in a second validation cohort of 101 patients with histologically confi rmed ALD. By ex-cluding those patients with GOT > 100 U/L at the time of LS assessment from this cohort,the area under the receiver operating characteristic (AUROC) for cirrhosis detection by FS improved from 0.921 to 0.945 while specificity increased from 80% to 90% at a sensitivity of 96%. A similar AUROC could be obtained for lower F3 fibrosis stage if LS measurements were restricted to patients with GOT < 50 U/L. Histological grading of inflammation did not further improve the diagnostic accuracy of LS.CONCLUSION:Coexisting steatohepatitis markedly increases LS in patients with ALD independent of fibrosis stage. Postponing cirrhosis assessment by FS during alcohol withdrawal until GOT decreases to < 100 U/mL signif icantly improves the diagnostic accuracy.Sebastian Mueller Gunda Millonig Lucie Sarovska Stefanie Friedrich Frank M Reimann Maria Pritsch Silke Eisele Felix Stickel Thomas Longerich Peter Schirmacher Helmut Karl Seitz 2010World Journal of Gastroenterology2010,16,8:10
3现代功率模块及器件应用技术(2)显示文摘现代的快速开关器件要求采用快速的二极管作为续流二极管。在每一次开关的开通过程中,续流二极管由导通切换到截止状态。这一过程要求二极管具有软恢复的特性。但是,在很长一段时期里,忽视了快速二极管的作用,使得开关器件工作频率的提高受到了限制。在过去的几年中,它又受到了高度的重视,特别是通过改善它的反向恢复特性而得到了长足的发展。Ulrich Nicolai Tobias Reimann 李毅 魏宇浩 2005电源技术应用2005,8,2:3
4Thermoelectric properties of silicon and recycled silicon sawing waste显示文摘Large-scale-applicable thermoelectric materials should be both self-sustaining,in order to survive longterm duty cycles,and nonpolluting.Among all classes of known thermoelectric materials,these criteria reduce the available candidate pool,leaving silicon as one of the remaining options.Here we first review the thermoelectric properties of various silicon-related materials with respect to their morphologies and microstructures.We then report the thermoelectric properties of silicon sawing wastes recycled from silicon wafer manufacturing.We obtain a high power factor of~32 mWcm1 K2 at 1273 K with 6%phosphorus substitution in the Si crystal,a value comparable to that of phosphorus-doped silicongermanium alloys.Our work suggests the large-scale thermoelectric applicability of recycled silicon that would otherwise contribute to the millions of tons of industrial waste produced by the semiconductor industry.Ran He Wieland Heyn Felix Thiel Nicolas Perez Christine Damm Darius Pohl Bernd Rellinghaus Christian Reimann Maximilian Beier Jochen Friedrich Hangtian Zhu Zhifeng Ren Kornelius Nielsch Gabi Schierning 2019Journal of Materiomics2019,5,1:2
