A carbon-supported Ru catalyst, Ru/BP2000, is able to simultaneously convert cellobiose into sorbitol and gluconic acid. This reaction occurs as the result of hydrolytic disproportionation in water at 393 K under an Ar atmosphere, without bases or sacrificial reagents. In-situ XANES measurements suggest that the active Ru species involved is composed of partially oxidized Ru metal.

A quasi-stationary alternating current （AC） operation assisted by lower hybrid waves （LHW） was achieved recently in HT-7. It is found that the particle confinement time of the positive current plasma is lower than that of the negative current plasma. The particle transport coefficients are investigated in AC plasmas by a gas puff modulation method. It is observed that the particle diffusion coefficient for the positive plasma current case is almost the same as that for the negative one, but the absolute value of inward pinch velocity for the positive current plasma is much lower than Vhat of the negative one. The result of the particle transport model study is in agreement with the experimental confinement study. The intensity of Hα emission and impurities emission of CⅢ, OII and OV for the negative current plasma are much lower than that for the positive current plasma. The radiation from Hα, OⅡ, CⅢ and ECE signals from the negative to the positive current phase showed less ionization and lower parameters than those from the positive to the negative one. The difference of particle transport and confinement in AC plasmas is not predicted by the current theory.

我们将早稻田大学校园内的4号楼改建为新的村上春树图书馆，成为一条穿过原有建筑的“木隧道”。木隧道超越了时间和空间，我们将村上春树小说中连接不同维度的“隧道”转译为建筑空间。我们通过将外墙重新漆成白色涂装和原来的建筑，强调了新建的三维木屏风雨棚。雨棚作为隧道入口的指示，也代表了维度之间的边界。这条木制隧道纵向贯穿了原有的楼板，同时用作书架、剧院和演讲厅。20世纪是混凝土的时代，混凝土具有“坚硬”和“冰冷”的特性。相比之下，对于这个图书馆，我们想象了一条隧道，通过使用细腻柔软的木材来保护我们、培育梦想。

This paper proposes a system for stable ladder climbing of the human-sized four-limbed robot“WAREC-1”,including the following 3 components:(a)Whole-body motion planning;(b)Rung recognition system and(c)Reaction force *** 3 components guarantee appropriate ladder climbing motion,successful rung grub and proper reaction force distribution at contact points throughout the climbing motion,*** this system,(1)Stable ladder climbing in 2-point contact gait by a human-sized robot and(2)Successful and stable climbing of an irregular ladder(with a higher or inclined rung)in both 3-point and 2-point contact gait with the capability of recognizing the target rung and the corresponding motion planning are realized,which have rarely been realized by former ***,experiment results and data of the robot ladder climbing are also presented to evaluate the proposed system.

Ketamine is a noncompetitive N-methyl-D-aspartate receptor （NMDAR） antagonist that has attracted wide- spread attention for its rapid-onset antidepressant effects, especially in individuals with treatment-resistant depres- sion and suicidal ideation [1-3]. Compared with the tra- ditional antidepressants that take weeks, if not months, to benefit patients and are associated with a high rate of relapse, ketamine exerts its antidepressant effects within several hours. These clinical benefits can last for 2 weeks after a single injection [1, 2, 4]. However, ketamine still has limited clinical application, psychotomimetic side-effects and liability of abuse. A recent paper in Nature [5] showed that the ketamine metabolite enantiomer （2R,6R）-hydroxynorketamine （HNK） has rapid and sustained antidepressant effects without the side-effects associated with ketamine, such as abuse potential. The discovery of （R）-ketamine is a land- mark in the field of depression. Investigations of its mechanism of action will inspire the development of a new

An outbreak of COVID-19 developed aboard the Princess Cruises Ship during January eFebruary *** mathematical modeling and time-series incidence data describing the trajectory of the outbreak among passengers and crew members,we characterize how the transmission potential varied over the course of the *** estimate of the mean reproduction number in the confined setting reached values as high as^11,which is higher than mean estimates reported from community-level transmission dynamics in China and Singapore(approximate range:1.1e7).Our findings suggest that Rt decreased substantially compared to values during the early phase after the Japanese government implemented an enhanced quarantine *** recent estimates of Rt reached values largely below the epidemic threshold,indicating that a secondary outbreak of the novel coronavirus was unlikely to occur aboard the Diamond Princess Ship.

Following an increase in the use of the GIA stapler for treating a pancreatic stump, more techniques to prevent postoperative pancreatic juice leakage have been required. We describe one successful case using our new technique of invaginating the cut end of the pancreas into the stomach to prevent a pancrea-tic fistula(PF) from occurring. A 50-year-old woman with pancreatic cancer in the tail of the pancreas underwent distal pancreatectomy, causing a grade A PF. We resected the distal pancreas without additional reinforcement to invaginate the stump into the gastric posterior wall with single layer anastomosis using a 3-0 absorbable suture. The drain tubes were removed on the third postoperative day. Although a grade A PF was noted, the patient was discharged on foot on the eleventh postoperative day. Our technique may be a suitable method for patients with a pancreatic body and tail tumor.
