| 1 | Clinical outcomes of ampullary neoplasms in resected margin positive or uncertain cases after endoscopic papillectomy显示文摘BACKGROUND Endoscopic papillectomy(EP) for benign ampullary neoplasms could be a lessinvasive alternative to pancreatoduodenectomy(PD). There are some problems and limitations with EP. The post-EP resection margins of ampullary tumors are often positive or uncertain because of the burning effect of EP. The clinical outcomes of resected margin positive or uncertain cases after EP remain unknown.AIM To investigate the clinical outcomes of resected margin positive or uncertain cases after EP.METHODS Between January 2007 and October 2018, all patients with ampullary tumors who underwent EP at Kobe University Hospital were included in this study. The indications for EP were as follows: adenoma, as determined by preoperative endoscopic biopsy, without bile/pancreatic duct extension, according to endoscopic ultrasound or intraductal ultrasound. The clinical outcomes of resected margin positive or uncertain cases after EP were retrospectively investigated.RESULTS Of the 45 patients, 29 were male, and 16 were female. The mean age of the patients was 65 years old. Forty-one patients(89.5%) underwent en bloc resection,and 4 patients(10.5%) underwent piecemeal resection. After EP, 33 tumors were histopathologically diagnosed as adenoma, and 12 were diagnosed as adenocarcinoma. The resected margins were positive or uncertain in 24 patients(53.3%). Of these cases, 15 and 9 were diagnosed as adenoma and adenocarcinoma, respectively. Follow-up observation was selected for all adenomas and 5 adenocarcinomas. In the remaining 4 adenocarcinoma cases,additional PD was performed. Additional PD was performed in 4 cases, and residual carcinoma was found after the additional PD in 1 of these cases. In the follow-up period, local tumor recurrence was detected in 3 cases. Two of these cases involved primary EP-diagnosed adenoma. The recurrent tumors were also adenomas detected by biopsy. The remaining case involved primary EPdiagnosed adenocarcinoma. The recurrent tumor was also an adenocarcinoma.All of the recurrent tumors were successfully treated with argon plasma coagulation(APC). There was no local or lymph node recurrence after the APC.The post-APC follow-up periods lasted for 57.1 to 133.8 mo. No ampullary tumor-related deaths occurred in all patients.CONCLUSION Resected margin positive or uncertain cases after EP could be managed by endoscopic treatment including APC, even in cases of adenocarcinoma. EP could become an effective less-invasive first-line treatment for early stage ampullary tumors. | Arata Sakai Masahiro Tsujimae Atsuhiro Masuda Takao Iemoto Shigeto Ashina Kohei Yamakawa Takeshi Tanaka Shunta Tanaka Yasutaka Yamada Ryota Nakano Yu Sato Manabu Kurosawa Takuya Ikegawa Seiji Fujigaki Takashi Kobayashi Hideyuki Shiomi Yoshifumi Arisaka Tomoo Itoh Yuzo Kodama | 2019 | World Journal of Gastroenterology2019，25，11： | 9 |
| 2 | 一种高频开关应用的新型1200V IGBT模块显示文摘医疗仪器、焊机和等离子切割机用电源的市场在不断扩大,这些设备工作在20~50kHz或更高的高频范围。本文讲述了近来开发的、用于这一高频领域的I G BT模块的设计理念。由于在这些应用中工作频段为高频范围,因此器件的开关损耗(开通、关断以及反向恢复损耗)是主要的功耗。通过降低背P+层载流子密度(注**——见正文),减小IGBT芯片中元胞的重复步距,并优化IGBT/FWD通态电压与开关损耗之间的折衷关系,可以得到更低的开关损耗。因而,这种新开发的IGBT模块的总功耗比标准IGBT模块(第5代系列)降低了25%。使用这种模块,能进一步提高效率、实现系统的小型化。 | Taku Takaku Shunta Horie Shogo Ogawa 李兴鲁 刘钺杨 吴郁 | 2010 | 电力电子2010，，4： | 2 |

| 4 | 可见光驱动改性氮化碳无牺牲剂光催化析氢显示文摘载铂石墨氮化碳(g-C_(3)N_(4))是一种较好的可见光下催化析氢光催化剂.但催化水裂解需要牺牲电子供体,如三乙醇胺等.目前,无牺牲剂条件下g-C_(3)N_(4)的催化析氢仍是一个挑战.本文通过尿素热处理制备了氮化碳纳米片(NS-C_(3)N_(4)),并研究了其在可见光(λ>400 nm)下利用可逆电子给体无牺牲剂条件下析氢的光催化活性.在含有I−,Fe^(2+)或[Fe(CN)_(6)]^(4−)的水溶液中,负载铂的NS-C_(3)N_(4)上无H_(2)产生,用CrO_(x)改性Pt/NS-C_(3)N_(4)的光催化剂上可观察到H_(2)的析出.透射电镜和能量色散X射线光谱结果表明,在NS-C_(3)N_(4)上形成了Pt/CrO_(x)核壳结构.在[Fe(CN)_(6)]^(3−/4−)氧化还原介质存在下,CrO_(x)/Pt/NS-C_(3)N_(4)与改性WO_(3)光催化剂在可见光下共同催化水分解析氢. | Shunta Nishioka Kengo Shibata Yugo Miseki Kazuhiro Sayama Kazuhiko Maeda | 2022 | Chinese Journal of Catalysis2022，43，9： | 1 |

| 9 | Coevolution of Myoelectric Hand Control under the Tactile Interaction among Fingers and Objects显示文摘The usability of a prosthetic hand difers significantly from that of a real hand.Moreover,the complexity of manipulation increases as the number of degrees of freedom to be controlled increases,making manipulation with biological signals extremely difficult.To overcome this problem,users need to select a grasping posture that is adaptive to the object and a stable grasping method that prevents the object from flling.In previous studies,these have been left to the operating skills of the user,which is extremely difficult to achieve.In this study,we demonstrate how stable and adaptive grasping can be achieved according to the object regardless of the user's operation technique.The required grasping technique is achieved by determining the correlation bet ween the motor output and each sensor through the interaction between the prosthetic hand and the surrounding stimuli,such as myoelectricity,sense of touch,and grasping objects.The agents of the 16 DOF robot hand were trained with the myoelectric signals of six participants,including one child with a congenital forearm deficiency.Consequently,each agent could open and close the hand in response to the myoeletric stimuli and could accomplish the object pickup task.For the tasks,the agents successfully identified grasping patterns suitable for practical and stable positioning of the objects.In addition,the agents were able to pick up the object in a similar posture regardless of the partiipant,suggesting that the hand was optimized by evolutionary computation to a posture that prevents the object from being dropped. | Yuki Kuroda Yusuke Yamanoi Shunta Togo Yinlai Jiang Hiroshi Yokoi | 2022 | Cyborg and Bionic Systems2022，，1： | 0 |
| 10 | Survey on Main Drive Methods Used in Humanoid Robotic Upper Limbs显示文摘Humanoid robotic upper limbs including the robotic hand and robotic arm are widely studied as the important parts of a humanoid robot.A robotic upper limb with light weight and high output can perform more tasks.The drive system is one of the main factors affecting the weight and output of the robotic upper limb,and therefore,the main purpose of this study is to compare and analyze the effects of the different drive methods on the overall structure.In this paper,we first introduce the advantages and disadvantages of the main drive methods such as tendon,gear,link,fluid(hydraulic and pneumatic),belt,chain,and screw drives.The design of the drive system is an essential factor to allow the humanoid robotic upper limb to exhibit the structural features and functions of the human upper limb.Therefore,the specific applications of each drive method on the humanoid robotic limbs are illustrated and briefly analyzed.Meanwhile,we compared the differences in the weight and payload(or grasping force)of the robotic hands and robotic arms with different drive methods.The results showed that the tendon drive system is easier to achieve light weight due to its simple structure,while the gear drive system can achieve a larger torque ratio,which results in a larger output torque.Further,the weight of the actuator accounts for a larger proportion of the total weight,and a reasonable external placement of the actuator is also beneficial to achieve light weight. | Yiwei Wang Wenyang Li Shunta Togo Hiroshi Yokoi Yinlai Jiang | 2021 | Cyborg and Bionic Systems2021，，1： | 0 |
| 11 | Learning Data Correction for Myoelectric Hand Based on“Survival of the Fittest”显示文摘In recent years,myoelectric hands have become multi-degree-of-freedom(DOF)devices,which are controlled via machine learning methods.However,currently,learning data for myoelectric hands are gathered manually and thus tend to be of low quality.Moreover,in the case of infants,gathering accurate learning data is nearly impossible because of the difficulty of communicating with them.Therefore,a method that automatically corrects errors in the learning data is necessary.Myoelectric hands are wearable robots and thus have volumetric and weight constraints that make it infeasible to store large amounts of data or apply complex processing methods.Compared with general machine learning methods such as image processing,those for myoelectric hands have limitations on the data storage,although the amount of data to be processed is quite large.If we can use this huge amount of processing data to correct the learning data without storing the processing data,the machine learning performance is expected to improve.We then propose a method for correcting the learning data through utilisation of the signals acquired during the use of the myoelectric hand.The proposed method is inspired by“survival of the fittest.”The effectiveness of the method was verified through offline analysis.The method reduced the amount of learning data and learning time by approximately a factor of 10 while maintaining classification rates.The classification rates improved for one participant but slightly deteriorated on average among all participants.To solve this problem,verifying the method via interactive learning will be necessary in the future. | Yusuke Yamanoi Shunta Togo Yinlai Jiang Hiroshi Yokoi | 2021 | Cyborg and Bionic Systems2021，，1： | 0 |
| 12 | 根据高频振幅峰值的到时快速估算地震震级显示文摘提出了一种利用加速度记录图中的体波初动与高频振幅峰值的到时差(T_(op))测量地震震级M的简单方法。用这种方式测量,我们发现,对于5≤M_W≤7的地震M_W与2logT_(op)成正比,如果T_(op)与震源尺度成正比并且应力降量级不变,这与理论结果相一致。使用高频(>2Hz)数据,M_W与M_(T_(op))(根据T_(op)估计的M)之间的均方根(rms)残差约为0.5个震级单位。在2~16Hz通带中高频数据的均方根残差,均匀地小于从较低频数据获得的值。T_(op)的值与震中距弱相关,在震中距<200km范围内可以忽略这种相关性。该算法对2011年日本东北地震的回顾性应用,在该地震发震时刻之后120s内做出M9.0的最终震级估算。我们由此得出结论,高频(>2Hz)加速度记录的T_(op)值,在发生特大地震时对地震预警很有价值。 | Shunta Noda Shunroku Yamamoto William L.Ellsworth 张立文(译) 吕春来(校) | 2017 | 世界地震译丛2017，48，3： | 0 |

| 14 | Predictive-based optimal automatic formation control of mobile vehicles显示文摘In recent years,formation control has received a great deal of attention as one of the most interesting issues in multiple mobile robots systems.In variable formation control systems,multiple mobile vehicles can form an appropriate formation from a list of possible formations,such that all mobile vehicles can pass even when the width of the course is narrow,and simultaneously the vehicles maintain a set distance between the course and each vehicle.This paper presents a predictive-based automatic formation control.In our formation control system,a unique formation is determined from feasible formations at any given sampling point.This control is formulated by its corresponding mixed-integer quadratic programing by introducing binary variables that are used to specify the formation.The effectiveness of the proposed methods is verified by applying two-wheeled mobile vehicles through simulations and experiments. | Tadanao Zanma Shunta Haga Kenta Koiwa Kang‐Zhi Liu | 2021 | IET Cyber-Systems and Robotics2021，3，4： | 0 |
| 15 | Effect of multifunction cavitation using phosphoric acid on fatigue and surface properties of AZ31 magnesium alloy显示文摘Magnesium alloy is attractive for lightweight construction but often suffers from poor corrosion resistance and low strength.Cavitation processing with chemicals,i.e.,multifunction cavitation(MFC),was introduced to form a high-corrosion film and improve the fatigue properties of an AZ31 magnesium alloy.Surface analysis and plane bending fatigue tests were conducted for the MFC-treated magnesium alloy at a stress ratio,R,of-1.The mechanical action of cavitation bubbles improved the fatigue life of magnesium alloys due to increasing the surface hardness and generating compressive residual stress.However,the combined mechanical and electrochemical action during MFC formed pits on the surface.These pits were large enough to easily nucleate an initial fatigue crack.In addition,the magnesium alloys without pit formation,for which a coating process using phosphoric acid was conducted after MFC using water,showed superior fatigue properties. | Shunta Matsuoka Fumihiro Kato Toshihiko Yoshimura Masataka Ijiri Shoichi Kikuchi | 2023 | Journal of Magnesium and Alloys2023，11，6： | 0 |
