1中美急诊道路交通伤患者流行病学研究显示文摘目的阐明中美两国综合性医院急诊医学科道路交通伤患者的异同点,为两国在道路交通伤临床、教学和科研方面的进一步合作提供新思路。方法选取2013年11—12月中国浙江省人民医院急诊医学科和2013年7—9月美国纽约州立大学上州医科大学急诊医学科两家单位的道路交通伤患者作为调查对象。双方合作设计《MVC Survey Questionare》(中英文版),供两家单位开展问卷调查。调查方法为标准流行病学抽样调查。调查内容包括患者到达急诊医学科的方式、交通工具、损伤类型、影像学检查情况、会诊情况、转归等。结果共发放问卷425份,回收合格问卷399份,有效率为93.9%,其中中国有效问卷155份,美国244份。到达急诊医学科的方式:美国道路交通伤患者救护车使用率高于中国,自备车使用率低于中国(P<0.05)。交通工具:美国自行车、电动车、行人交通事故发生率低于中国,汽车交通事故发生率高于中国(P<0.05)。损伤类型:美国患者颅脑、皮肤软组织损伤发生率低于中国,胸部损伤、骨折发生率高于中国(P<0.05)。影像学检查:美国患者X线、CT检查率均高于中国(P<0.05)。两国住院率、病死率、救治成功出院率、入住ICU比例、急诊手术率比较,差异均无统计学意义(P>0.05)。结论与美国相比,中国较少选择救护车转运道路交通伤患者。中国有更多类型的机动车涉及道路交通伤事故,中国道路交通伤患者中骑电动车、摩托车和行人的比例较高,这在一定程度上导致了中国颅脑损伤的比例远高于美国。另外,中国患者影像学检查率明显低于美国。上述差异为未来双方在道路交通伤临床、教学和科研方面开展进一步合作提供了新思路。涂建锋 张可 周晟昂 陈环 蔡文伟 PaulKo Susan Wojcik Sabine Khan William D.

3Generalized Predictive Control for Superheated Steam Temperature Regulation in a Supercritical Coal-fired Power Plant显示文摘The design and implementation of a Generalized Predictive Control(GPC)strategy for the superheated steam temperature regulation in a supercritical(SC)coal-fired power plant is presented.A Controlled Auto-Regressive MovingAverage(CARMA)model of the plant is derived from using the experimental data to approximately predict the plant’s future behavior.This model is required by the GPC algorithm to calculate the future control inputs.A new GPC controller is designed and its performance is tested through extensive simulation studies.Compared with the performance of the plant using a conventional PID controller,the steam temperature controlled by the GPC controller is found to be more stable.The stable steam temperature leads to more efficient plant operation and energy saving,as demonstrated by the simulation results.Plant performance improvement is also tested while the plant experiences the load demand changes and disturbances resulting from the malfunctioning of coal mills.Mihai Draganescu Shen Guo Jacek Wojcik Jihong Wang Xiangjie Liu Guolian Hou Yali Xue Qirui Gao 2015CSEE Journal of Power and Energy Systems2015,1,1:7
4B cell development is critically dependent on NFATc1 activity显示文摘B cell development in bone marrow is a precisely regulated complex process.Through successive stages of differentiation,which are regulated by a multitude of signaling pathways and an array of lineage-specific transcription factors,the common lymphoid progenitors ultimately give rise to mature B cells.Similar to early thymocyte development in the thymus,early B cell development in bone marrow is critically dependent on IL-7 signaling.During this IL-7-dependent stage of differentiation,several transcription factors,such as E2A,EBF1,and Pax5,among others,play indispensable roles in B lineage specification and maintenance.Although recent studies have implicated several other transcription factors in B cell development,the role of NFATc1 in early B cell developmental stages is not known.Here,using multiple gene-manipulated mouse models and applying various experimental methods,we show that NFATc1 activity is vital for early B cell differentiation.Lack of NFATc1 activity in pro-B cells suppresses EBF1 expression,impairs immunoglobulin gene rearrangement,and thereby preBCR formation,resulting in defective B cell development.Overall,deficiency in NFATc1 activity arrested the pro-B cell transition to the pre-B cell stage,leading to severe B cell lymphopenia.Our findings suggest that,along with other transcription factors,NFATc1 is a critical component of the signaling mechanism that facilitates early B cell differentiation.Sabrina Giampaolo Gabriela Wojcik Stefan Klein-Hessling Edgar Serfling Amiya K.Patra 2019Cellular & Molecular Immunology2019,16,5:3
5Effects of the Facet Reflectivity of a Laser Diode on Fiber Bragg Grating Semiconductor Lasers显示文摘Effects of facet reflectivity of a laser diode on the performance of fiber Bragg grating semiconductor lasers are studied experimentally. Facet reflectivity of less than 10-4 is necessary to obtain stable oscillation wavelength.Honggang Yu Chang-Qing Xu Na Li Zhilin Peng Jacek Wojcik Peter Mascher 2003光学学报2003,23,S1:2
6Effects of a variety of cutting fluids administered using the minimum quantity lubrication method on the surface grinding process for nickel-based alloys显示文摘This paper presents the characteristics of nickel-based alloys, alongside their division into groups, and describes thefeatures that make such materials difficult to grind. The possibilities of exerting a positive influence upon machining conditions,especially through the proper application of grinding fluids, are briefly presented. Both the precise methodologies for, and theresults of, the experimental tests carried out on flat surfaces are also detailed. The aim of these tests was to determine the influenceof the application of two types of grinding liquid (Ecocut Mikro Plus 82 and Biocut 3000) upon the grinding force values andsurface roughness of the machined workpieces made from three nickel alloys (Nickel 201, INCONEL~ alloy 600, and MONEL^alloy 400). An additional goal of the tests was to determine the influence of grinding wheel structure on the course and results ofthe machining process. The results indicate that the physical and chemical properties of Biocut 3000 enabled the most advanta-geous properties of the machined surface roughness, alongside a simultaneous increase in grinding power, when compared to theresults when applying Ecocut Mikro Plus 82. The results showed an almost inversely proportional dependence upon the specifictangential grinding force Ft' and arithmetic mean deviation of the surface profile Ra values, especially in cases of machining Nickel201 and INCONEL alloy 600. The original traverse grinding methodology used in the tests made it possible to assess the changesof the grinding conditions within the conventionally selected zones.Ryszard WOJCIK Krzysztof NADOLNY 2017Journal of Zhejiang University-Science A(Applied Physics & Engineering)2017,18,9:2
