A Study on the Sensor Applications for Position Detection and Guideway Monitoring in High Speed Maglev

引用

Modern Mechanical Engineering 2014年第4期4卷 165-174页

作者： Jinho lee Jeongmin Jo Yongjae Han Changyoung lee Yan Sun Maglev Train Research Team Korea Railroad Research Institute Uiwang-si Republic of Korea

The high speed maglev is mainly characterized by propulsion using linear synchronous motor (LSM) and vehicle levitation from the guideway surface. In LSM propulsion control, the position detection sensor is used to detect running vehicle position for synchronized current generation. To maintain the stable levitating condition during vehicle running, the irregularity of guideway surface should be monitored by sensors measuring the displacement and acceleration between vehicle and guideway. In this study, the application methods of these sensors in the high speed maglev are investigated and through the experiments by using the small-scale test bed, the validity of examined methods is confirmed.

A Retroperitoneal Inflammatory Myofibroblastic Tumor Mimicking a Germ Cell Tumor of the Undescended Testis: A Case Report and Literature Review

引用

Advances in Computed Tomography 2016年第3期5卷 35-41页

作者： Seul-Bi lee Jung-Hee Yoon Seung-Ho Kim Yedaun lee Jin-Soo lee Jung-Wook Seo Department of Radiology Inje University Haeundae Paik Hospital College of Medicine Busan South Korea Department of Radiology Inje University Ilsan Paik Hospital College of Medicine Goyang-si South Korea

We report here a case of an inflammatory myofibroblastic tumor in the retroperitoneum, which mimicked a germ cell tumor of the undescended testis. A 75-year-old healthy man presented with a palpable abdominal mass. On the computed tomography image, there was large, well-defined soft tissue mass in the left side of the retroperitoneum, and there was no visible left testis or seminal vesicle. After contrast enhancement, the mass appeared to be relatively homogeneous, considering its large size. With ultrasonography, it appeared as a well-defined, hypoechoic mass with intratumoral vascularity. This solid mass was surgically diagnosed as an inflammatory myofibroblastic tumor.

CAPPh A Cytoskeleton-Based Localization Assay Reports Protein-Protein Interaction in Living Cells by Fluorescence Microscopy

Molecular Plant 2017年第11期10卷 1473-1476页

Dear EditorProbing protein-protein interaction has become a routine practice in the post genomic era. Multiple in vitro or in vivo techniques have been developed to detect or report direct or indirect interactions of functionally related proteins （Lalonde et al., 2008）. These techniques sometimes are technically challenging, however, because the readout would demand sophisticated detectors and/or complicated calculations. Besides, a common drawback of many of these techniques is they can render inherent false positives to various degrees so that an interaction often cannot be judged unambiguously.

Improvement of resolution in 2-D gel analysis by simple pre-treatment of human urine with EDTA

引用

Open Journal of Clinical Diagnostics 2012年第2期2卷 40-43页

作者： Jin-Woo lee Ju-Young lee Jinkyu Lim Department of Animal Science and Biotechnology Kyungpook University Daegu Korea

Regardless of thermodynamic stability, less complex proteome than plasma, convenient and noninvasive sampling of urine, reproducibility and comparability of the data among laboratories are challenges for the urine proteome analysis. Pretreatment of urine with 10 mM EDTA in conjunction with desalting methods to remove interfering molecules significantly improved the presentation of urine proteome on 2-D gels. Statistical analysis of the average ratio of the spot numbers on 2-D gels between EDTA-treated and non-treated samples were 1.35 ± 0.167, 1.26 ± 0.091, and 1.24 ± 0.095 for dialysis, ultrafiltration, and desalting column, respectively, with the p-value of 5.85 × 10–6 for the overall comparison. This result came from the fact that EDTA-treated samples showed better resolutions with less streaks and clearer spots on 2-D gels than the control samples. The results suggest that a simple and non-fractionating EDTA-treatment can be employed to the procedures for the high resolution 2-D gel analysis and other urinary proteomic analysis.

该项研究中采用三种不同焊料 (W 4 0 ,BAg - 1,BAg3S)对低碳钢锯片基体和青铜基烧结刀头进行焊接。使用DIEXCorp(迪爱克斯公司 )SAB7型高频感应焊接机进行焊接实验。利用OLM(金相分析 ) ,SEM(扫描电子显微镜 ) ,EDS(能谱分析 )和XRD(X射线衍射分析 )等手段对不同焊接温度与时间条件下焊接区的焊缝宽度、气孔率和显微结构进行了评价。为了评价焊接强度 ,还进行了抗弯强度 (扭矩 )测试。焊接温度对焊缝强度有较大影响。对于青铜基刀头和锯片钢基体的匹配焊接 ,其合理的焊接温度为 70 0～ 850℃。焊接区的反应程度 ,气孔含量和焊缝宽度三个因素影响焊接强度。在青铜基刀头靠近接面处形成反应区 ,由于在该区形成富Cu相 ,Cu5.6Sn ,CuZn4 ,β(CuZn)和CdAg相 ,而对焊接强度产生有害影响。当焊接温度提高 ,焊接时间增加 ,则气孔率将增大。当焊缝区气孔率小于 3～ 5%时 ,则青铜基刀头将获得最佳强度。焊缝宽度大于 30

AIMTo investigate the benefits of the Seattle protocol in the diagnosis of Chinese individuals with Barrett’s *** enrolled were patients from one center with endoscopically-suspected esophageal metaplasia. These patients first received narrow-band imaging-targeted biopsy, and later, the Seattle protocol-guided biopsy, within a period from October 2012 to December 2014. Those cases without initial pathologic patterns of intestinal metaplasia （IM） and then appearance or loss of IM tissue were designated as Group A or B, respectively. Those with initial pathologic patterns ofIM, which then persisted or were lost were designated as Group C or D, *** number of cases for each group was as follows： A： 20, B： 78, C： 31 and D： 14. The distribution of the Prague criteria M levels of Group A was significantly higher than Group B （ P = 0.174）. Among these groups, Group C had the highest proportions of hiatus hernia （54.8%）, long segment Barrett’s esophagus （29%）, and also the highest Prague criteria M levels. The sensitivity of IM detection was 69.2% for the narrow-band imaging-targeted biopsy and 78.5% for the lee SW et al . Seattle protocol for Barrett’s esophagusSeattle protocol-guided biopsy. The difference was not signifcant （P = 0.231）. The number of detectable dysplasias increased from one case via the NBI-target biopsy to five cases via the Seattle protocol-guided biopsy, including one case of *** Seattle protocol improved the IM detection in our subjects with higher Prague criteria M levels and disclosed more cases with dysplastic tissues.
