| 1 | An Outbreak of Multidrug-Resistant Tuberculosis in a Secondary School --Hubei Province, 2019显示文摘What is already known about this topic?Multidrug-resistant tuberculosis(MDR-TB)is a type of tuberculosis with resistance to common treatments such as isoniazid and rifampicin.MDR-TB is a major global health challenge and needs to be controlled tightly through prevention measures,early diagnosis,and full treatment and management.What is added by this report?This outbreak was the first MDR-TB related public health emergency in Hubei Province.In total,five MDR-TB cases and nine clinically diagnosed cases were identified within one class in a secondary school.Students and teachers from other classes were monitored,but no other cases were found.What are the implications for public health practice?The implementation of TB prevention and control measures in schools is important to increase knowledge on TB and to raise awareness on protecting personal wellbeing.The Automatic Early Warning Information System alerted the local health department and allowed for a timely response to prevent further disease spread. | Mengxian Zhang Tang Wang Shuangyi Hou Jianjun Ye Liping Zhou Zhong Zhang Zhiqiang Deng Qin Da Guoming Li Shiyue Li | 2019 | China CDC weekly2019，1，5： | 5 |
| 2 | TIO: A VLC-Enabled Hybrid Data Center Network Architecture显示文摘To satisfy the ever-increasing bandwidth demand of modern data centers, researchers have proposed hybrid Data Center Networks(DCNs), which employ high-bandwidth Optical Circuit Switches(OCSs) to compensate for Electrical Packet Switches(EPS). Existing designs, such as Helios and c-Through, mainly focus on reconfiguring optical devices to meet the estimated traffic requirements. However, these designs face two major challenges in their OCS-based networks, namely, the complex control mechanism and cabling problems. To solve these challenges, we propose TIO, a hybrid DCN that employs Visible Light Communication(VLC) instead of wired OCS design to connect racks. TIO integrates the wireless VLC-based Jellyfish and wired EPS-based Fat Tree seamlessly and combines the opposite and complementary characteristics, including wireless VLC direct connection and wired electrical packet switching, random graph, and Clos topology properties. To further exploit the merits of TIO, we design a hybrid routing scheme and congestion-aware flow scheduling method. Comprehensive evaluations indicate that TIO outperforms the Jellyfish and Fat Tree in both topology properties and network performance, and the flow scheduling method also evidently improves performance. | Yudong Qin Deke Guo Guoming Tang Bangbang Ren | 2019 | Tsinghua Science and Technology2019，24，4： | 2 |
| 3 | Kinematics Analysis of Motion Simulation Subsystem for Unmanned Vehicle显示文摘Unmanned vehicle has attracted wide attention and interests throughout the world since it first deputed in the 1960s. However, the experimental methods for unmanned vehicle's intelligent behavior, such as semi-physical simulation and motion subsystem, have not been widely explored. First, the requirements of the motion subsystem in unmanned vehicle semi-physical facility are analyzed, and a six DOF parallel manipulator is selected to reproduce the pose of the vehicle. The link lengths of the motion subsystem are worked out under the given rotational angles of the vehicle. According to the geometric properties of tetrahedron, three joint positions of the top platform are determined, and the rest are obtained from the first three position vectors. Six constraint equations are set up based on the vertices on the top platform and the link lengths. In order to solve the six angle variables, a numerical algorithm built on the Newton-Raphson iterative method is presented, which is based on Taylor series expansion of six constraint equations. The pose of the top platform is ultimately calculated. The eigenvalues of the top platform are solved to obtain the natural frequencies of the motion subsystem. The coordinates of six joint centers on the top platform and six constraint equations can be realized by simple algebraic manipulation, which allows significant abbreviation in the formulation and provides a systematic way of obtaining the kinematic solution of the parallel manipulator. A numerical example is given and its efficacy is demonstrated by the inverse kinematics. The computation strategy based on tetrahedron method and Newton-Raphson iterative method provide a simple and cost-effective method for solving forward kinematics of six DOF parallel manipulators, and this method sheds light on other parallel manipulators. | TANG Guoming MEI Tao LIU Wei LI Bichun | 2011 | Chinese Journal of Mechanical Engineering2011，24，6： | 1 |
| 4 | The impact of Typhoon Lekima (2019) on East China: a postevent survey in Wenzhou City and Taizhou City显示文摘Typhoon Lekima(2019)struck Zhejiang Province on 10 August 2019 as a supertyphoon,which severely impacted Zhejiang Province.The typhoon killed 45 people and left three others missing,and the total economic loss reached 40.71 billion yuan.This paper reports a postdisaster survey that focuses on the storm precipitation,flooding,landslides,and weather services associated with Typhoon Lekima(2019)along the southeastern coastline of Zhejiang Province.The survey was conducted by a joint survey team from the Shanghai Typhoon Institute and local meteorological bureaus from 26 to 28 August,2019,approximately two weeks after the disaster.Based on this survey and subsequent analyses of the results,we hope to develop countermeasures to prevent future tragedies. | Cong ZHOU Peiyan CHEN Shifang YANG Feng ZHENG Hui YU Jie TANG Yi LU Guoming CHEN Xiaoqing LU Xiping ZHANG Jing SUN | 2022 | Frontiers of Earth Science2022，16，1： | 1 |
| 5 | Wind erosion from crusted playa surfaces by no saltation and with saltation:A comparison through laboratory wind tunnel experiments显示文摘Playas are common in many arid regions and recognized as a major source of hypersaline particles.A better understanding of wind erosion on crusted playas has significant implications for land management and pollution control practices.We hypothesized that wind erosion rates of crusted playas were complicated and controlled by the interactions between playa crust and wind-induced saltation conditions.However,comparisons regarding the effects of different playa crusts on wind erosion under no saltation(NS)and with saltation(WS)conditions were lacking.In this study,laboratory wind tunnel experiments were carried out to simulate both NS and WS conditions,to investigate the erosion rates of different crust types(Salt,Takyr,and Puffic crust)at different wind speeds.Results showed that:1)Salt crust had greater crust strengths than did Takyr crust and Puffic crust;2)wind erosion rates under the WS condition were up to 60 times greater than those under the NS condition,suggesting that sand bombardment was the dominant mechanism responsible for removal of fine material from crusted playa surfaces;3)both sand bombardment rate and wind erosion rate of the playa crusts increased with increasing wind speed under the WS conditions;4)Puffic crust exhibited a greater rate of wind erosion compared to both the Takyr and Salt crusts under the Ns condition,yet tended to have a lower rate of wind erosion compared to both the Takyr and Salt crusts under the WS condition.This difference can be attributed to the fact that soft Puffic crusts are pliable and can dissipate the force of impacting grains under the Ws conditions.Our results indicated that wind erosion processes on crusted playas are complicated and are affected by wind-induced saltation and crust type,specifically crust strength and elasticityofthesurface. | Guoming Zhang Li Li Wenjian Tang Lianyou Liu Peijun Shi Xujiao Han jiadong Dai | 2023 | International Soil and Water Conservation Research2023，11，3： | 0 |
| 6 | Microstructure Evolution and Its Effect on Mechanical Properties in an Electron Beam Weldedβ-Solidified TiAl Alloy显示文摘TiAl alloys are susceptible to cracks during electron beam welding because their limited ductility cannot accommodate the stress generated under fast cooling rate.In this work,pre-heating and post-heating via defocused electron beam were used to obtain well-welded joints without cracks.Lower crack sensitivity of joints was attributed to the microstructure evolution to obtain more ability of stress accommodation with the increasing heating beam current and heating time.Long-time pre-heating of 5 min and post-heating of 12 min led to reduced volume fraction of residualβ0 phase with the growth ofα2/γlamellar colonies in the fusion zone(FZ).The refined microstructure of FZ contributed to the highest hardness of the FZ,and the fracture happened at the base material(BM)in tensile tests,indicating that the tensile properties of the welding seam surpassed that of the BM.This work provides an effective way to obtain TiAl joints with better mechanical properties of the welding seam than that of the BM,which is a breakthrough in the welding of TiAl alloys. | Songkuan Zhao Bin Tang Guoming Zheng Mengqi Zhang Wei Chen Tong Zhao Beibei Wei Lei Zhu Jinshan Li | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，10： | 0 |
