To comprehensively understand the Arctic and Antarctic upper atmosphere, it is often crucial to analyze various data that are obtained from many regions. Infrastructure that promotes such interdisciplinary studies on the upper atmosphere has been developed by a Japanese inter-university project called the Inter-university Upper atmosphere Global Observation Network （1UGONET）. The objective of this paper is to describe the infrastructure and tools developed by IUGONET. We focus on the data analysis software. It is written in Interactive Data Language （IDL） and is a plug-in for the THEMIS Data Analysis Software suite （TDAS）, which is a set of IDL libraries used to visualize and analyze satellite- and ground-based data. We present plots of upper atmospheric data provided by IUGONET as examples of applications, and verify the usefulness of the software in the study of polar science. We discuss IUGONET＇s new and unique developments, i.e., an executable file of TDAS that can run on the IDL Virtual Machine, IDL routines to retrieve metadata from the IUGONET database, and an archive of 3-D simulation data that uses the Common Data Format so that it can easily be used with TDAS.

An integrated analysis platform merging SuperDARN data within the THEMIS tool developed by ERG-Science Center (ERG-SC)

Advances in Polar Science 2013年第1期24卷 69-77页

The Energization and Radiation in Geospace （ERG） mission seeks to explore the dynamics of the radiation belts in the Earth＇s inner magnetosphere with a space-borne probe （ERG satellite） in coordination with related ground observations and simulations/modeling studies. For this mission, the Science Center of the ERG project （ERG-SC） will provide a useful data analysis platform based on the THEMIS Data Analysis software Suite （TDAS）, which has been widely used by researchers in many conjunction studies of the Time History of Events and Macroscale Interactions during Substorms （THEMIS） spacecraft and ground data. To import SuperDARN data to this highly useful platform, ERG-SC, in close collaboration with SuperDARN groups, developed the Common Data Format （CDF） design suitable for fitacf data and has prepared an open database of SuperDARN data archived in CDE ERG-SC has also been developing programs written in Interactive Data Language （IDL） to load fltacf CDF files and to generate various kinds of plots-not only range-time-intensity-type plots but also two-dimensional map plots that can be superposed with other data, such as all-sky images of THEMIS-GBO and orbital footprints of various satellites. The CDF-TDAS scheme developed by ERG-SC will make it easier for researchers who are not familiar with SuperDARN data to access and analyze SuperDARN data and thereby facilitate collaborative studies with satellite data, such as the inner magnetosphere data pro- vided by the ERG （Japan）-RBSP （USA）-THEMIS （USA） fleet.

线粒体可增强RNA病毒侵染引起的细胞先天免疫。线粒体介导的先天免疫通过信号分子调节聚集到线粒体膜,并依赖于线粒体内膜电位(Δψm)。本试验主要研究线粒体膜电位的生理学相关性及先天免疫中与线粒体相关的甲型流感病毒蛋白PB1-F2。当在宿主细胞中表达时,PB1-F2经由Tom40渠道完全转位到线粒体内膜空间,它的积累促进了因线粒体膜电位降低而导致的线粒体碎片的生成。相比之下,在低致病亚型病毒中发现的缺乏C-末端多肽的PB1-F2变体却不影响线粒体功能。PB1-F2介导的线粒体膜电位的降低抑制RIG-I信号通路及NLRP3炎症因子的激活。结果表明PB1-F2转位到线粒体与受损细胞先天免疫密切相关,使这种易位成为一个潜在的治疗靶点。

2014年,丰田汽车公司推出了全球首款商用燃料电池汽车(FCV)MIRAI[1]。与第1代MIRAI车型使用的燃料电池(FC)电堆相比,新款MIRAI车型使用的燃料电池堆采用了新的双极板流道和改进的电极,成为世界上体积功率密度最高的产品之一,其功率密度为5.4kW/L(不包括端板),性能比第1代MIRAI车型的燃料电池堆提高了1.5倍[2]。提高电流密度是提高动力系统功率性能、减小体积的重要手段,双极板的作用是在电池内部合理地分配气体和排水,以稳定电流的产生。传统的直流通路容易被水淹没,很难维持稳定的电流。为了提高氧气的扩散效率,设计了1个局部窄流道,而不需要在原燃料电池堆中采用三维网格流场。这项新技术可使催化剂层中的氧浓度比传统的直流通道高2.3倍。除双极板外,催化剂载体和离聚物也得到了改进。铂(Pt)表面的离聚物会引起磺酸中毒,导致催化活性下降。为了解决这一难题,开发了介孔碳作为催化剂载体,在介孔碳的孔中携带Pt,通过减少离聚物与Pt表面的接触来抑制磺酸中毒。采用了1种高透氧离聚物,其透氧性能是先前燃料电池堆使用的离聚物的3倍。

8层和16层多层CT检查冠状动脉节段的可见度和图像质量的比较

世界核心医学期刊文摘（心脏病学分册） 2005年第7期1卷 58-58页

作者： Maruyama T. yoshizumi T. Tamura R. 李天霞 Dr.Dept. of Int. Med. and Molec. Sci. Graduate School of Medicine Osaka University 2-2 Yamadaoka Suita Osaka 565-0871 Japan

Ten patients who underwent conventional coronary angiography(CA) were examined with both 8-and 16-slice multidetector-row computed tomography(MDCT) angiography within 6 months, and visibility and image quality of 16-slice MDCT-CA were compared with those of 8-slice MDCT-CA directly. In 136 segments determined by conventional CA, 101(74.3%) and 126(92.6%) segments were judged assessable by 8-and 16-slice MDCT-CA, respectively. Segment visibility in the right coronary and left circumflex arteries, as well as distal segments and small segments with diameters of< 3.0 mm, was higher using 16-slice MDCT-CA than that of 8-slice MDCTCA. As causes for invisibility in segments considered to be invisible, adjacent structures, as well as small diameters, were reduced by 16-slice MDCT-CA, suggesting that high spatial resolution contributes to higher visibility; however, nonassessable segments due to extensive calcium by 8-slice MDCT-CA were also judged nonassessable by 16-slice MDCT-CA.
