| 1 | Endoscopic and clinicopathologic characteristics of early gastric cancer with high microsatellite instability显示文摘AIM:To investigate endoscopic and clinicopathologic characteristics of early gastric cancer (EGC) according to microsatellite instability phenotype.METHODS:Data were retrospectively collected from a single tertiary referral center.Of 981 EGC patients surgically treated between December 2003 and October 2007,73 consecutive EGC patients with two or more microsatellite instability (MSI) mutation [high MSI (MSI-H)] and 146 consecutive EGC patients with one or no MSI mutation (non-MSI-H) were selected.The endoscopic and clinicopathologic features were compared between the MSI-H and non-MSI-H EGC groups.RESULTS:In terms of endoscopic characteristics,MSI-H EGCs more frequently presented with elevated pattern (OR 4.38,95% CI:2.40-8.01,P < 0.001),moderateto-severe atrophy in the surrounding mucosa (OR 1.91,95% CI:1.05-3.47,P = 0.033),antral location (OR 3.99,95% CI:2.12-7.52,P < 0.001) and synchronous lesions,compared to non-MSI-H EGCs (OR 2.65,95% CI:1.16-6.07,P = 0.021).Other significant clinicopathologic characteristics of MSI-H EGC included predominance of female sex (OR 2.77,95% CI:1.53-4.99,P < 0.001),older age (> 70 years) (OR 3.30,95% CI:1.57-6.92,P = 0.002),better histologic differentiation (OR 2.35,95% CI:1.27-4.34,P = 0.007),intestinal type by Lauren classification (OR 2.34,95% CI:1.15-4.76,P = 0.019),absence of a signet ring cell component (OR 2.44,95% CI:1.02-5.86,P = 0.046),presence of mucinous component (OR 5.06,95% CI:1.27-20.17,P = 0.022),moderate-to-severe lymphoid stromal reaction (OR 3.95,95% CI:1.59-9.80,P = 0.003),and co-existing underlying adenoma (OR 2.66,95% CI:1.43-4.95,P = 0.002).CONCLUSION:MSI-H EGC is associated with unique endoscopic and clinicopathologic characteristics including frequent presentation in protruded type,co-existing underlying adenoma,and synchronous lesions. | Jaehoon Jahng Young Hoon Youn Kwang Hyun Kim Junghwan Yu Yong Chan Lee Woo Jin Hyung Sung Hoon Noh Hyunki Kim Hoguen Kim Hyojin Park Sang In Lee | 2012 | World Journal of Gastroenterology2012，18，27： | 6 |
| 2 | 纯铜高压扭转压缩阶段塑性变形的实验及有限元分析(英文)显示文摘利用实验及有限元分析等手段,对纯铜高压扭转压缩阶段的塑性变形行为、硬度及显微组织分布进行了研究,结果表明,试样经压缩后,其硬度分布极为不均匀,边缘硬度高,轴心部位硬度低,而中间部位硬度变化较为平缓。模拟结果显示,试样在压缩过程中的应力应变呈不均匀变化,由此引起试样各部位显微组织及晶粒变形不均匀。进一步研究表明,试样与模具间的摩擦对于压缩阶段试样变形具有重要影响。 | 王文珂 宋月鹏 高东升 JungHwan Lee EunYoo Yoon DongJun Lee ChongSoo Lee HyoungSeop Kim | 2013 | 稀有金属材料与工程2013，42，S2： | 4 |
| 3 | Fast Model-based Design of High Performance Permanent Magnet Machine for Next Generation Electric Propulsion for Urban Aerial Vehicle Application显示文摘Model order reduction(MOR)is considered as a good alternative to reduce the computational scale for electro-magnetic problems.The aim of this work is to introduce the use of dynamic mode decomposition(DMD)as a promising tool for MOR to analyze its effectiveness in creating a fast model-based design platform for the permanent magnet motor design for ur-ban aerial vehicles(UAVs).Using a singular value decomposition(SVD)based DMD,the design process is constructed and verified against different scenarios. | Sarbajit Paul Junghwan Chang | 2021 | CES Transactions on Electrical Machines and Systems2021，5，2： | 3 |
| 4 | Robotic Intra-Operative Ultrasound:Virtual Environments and Parallel Systems显示文摘Robotic intra-operative ultrasound has the potential to improve the conventional practice of diagnosis and procedure guidance that are currently performed manually.Working towards automatic or semi-automatic ultrasound,being able to define ultrasound views and the corresponding probe poses via intelligent approaches become crucial.Based on the concept of parallel system which incorporates the ingredients of artificial systems,computational experiments,and parallel execution,this paper utilized a recent developed robotic trans-esophageal ultrasound system as the study object to explore the method for developing the corresponding virtual environments and present the potential applications of such systems.The proposed virtual system includes the use of 3 D slicer as the main workspace and graphic user interface(GUI),Matlab engine to provide robotic control algorithms and customized functions,and PLUS(Public software Library for Ultra Sound imaging research)toolkit to generate simulated ultrasound images.Detailed implementation methods were presented and the proposed features of the system were explained.Based on this virtual system,example uses and case studies were presented to demonstrate its capabilities when used together with the physical TEE robot.This includes standard view definition and customized view optimization for pre-planning and navigation,as well as robotic control algorithm evaluations to facilitate real-time automatic probe pose adjustments.To conclude,the proposed virtual system would be a powerful tool to facilitate the further developments and clinical uses of the robotic intra-operative ultrasound systems. | Shuangyi Wang James Housden Tianxiang Bai Hongbin Liu Junghwan Back Davinder Singh Kawal Rhode Zeng-Guang Hou Fei-Yue Wang | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，5： | 3 |

| 6 | Zn-doped nickel iron(oxy)hydroxide nanocubes passivated by polyanions with high catalytic activity and corrosion resistance for seawater oxidation显示文摘Electrochemical water splitting to produce hydrogen fuel is a promising renewable energy-conversion technique.Large-scale electrolysis of freshwater may deplete water resources and cause water scarcity worldwide.Thus,seawater electrolysis is a potential solution to the future energy and water crisis.In seawater electrolysis,it is critical to develop cost-effective electrocatalysts to split seawater without chloride corrosion.Herein,we present zinc-doped nickel iron(oxy)hydroxide nanocubes passivated by negatively charged polyanions(NFZ-PBA-S)that exhibits outstanding catalytic activity,stability,and selectivity for seawater oxidation.Zn dopants and polyanion-rich passivated surface layers in NFZ-PBA-S could effectively repel chlorine ions and enhance corrosion resistance,enabling its excellent catalytic activity and stability for seawater oxidation. | So Jung Kim Heechae Choi Jeong Ho Ryu Kang Min Kim Sungwook Mhin Arpan Kumar Nayak Junghwan Bang Minyeong Je Ghulam Ali Kyung Yoon Chung Kyeong-Han Na Won-Youl Choi Sunghwan Yeo Jin Uk Jang HyukSu Han | 2023 | Journal of Energy Chemistry2023，，6： | 1 |
