| 1 | Numerical prediction experiment on Typhoon Maggie (9903)显示文摘The movement of Typhoon Maggie (9903) in June 1999 is one of the rare cases ever seen in the history. At 00U on June 6 Maggie was located at about 70 km to the southwest of Taiwan. When it arrived at the coastal region of Shanwei City (22.8N, 116.5E), it turned suddenly to move southwestward along the southern China coastal line. De June 7 Maggie finally turned to move northward, making landfall to the north of Shangchuan Island. The experimental numerical prediction system on typhoon movement that was designed based on MM5 is proved quite successful for the 48h prediction of Maggie’s movement and rainfall. The mean prediction error of typhoon track is 81 km for 0-24 h and 74 km for 24-48 h. The location of typhoon center in the initial field of the model is approximately 100 km away from the actual observations. In order to modify the location of typhoon center, a bogus typhoon was intro- duced into the model and the prediction of typhoon track was improved in 0-24 h time interval. But the prediction error was enlarged in 24-36 h. We also performed a sensitivity experiment of changing the land of southern China into the ocean. It is found that the orientation of South China coastal line and the topography have no obvious effect on the movement of Typhoon Maggie. | Fong Soi Kun, Wu Chisheng, Hao I Pan, Lam Kin Hang Ku Chi Meng, Wang Anyu, Lin Wenshi (1.

| 2 | Spatiotemporal Changes of Hazard Intensity-Adjusted Population Exposure to Multiple Hazards in Tibet During 1982–2015显示文摘The dynamic changes of population exposure to hazards in high-altitude areas are an important factor in the scientific evaluation of environmental risks. In this study,the hazards of hypoxia, earthquakes, and snowstorms in Tibet were respectively described by the percentage of oxygen at sea level, earthquake intensity, and mean annual maximum snow depth. The rates of population affected by hypoxia, earthquakes, and snowstorms were calculated by chronic mountain sickness and historical disaster data.Based on these, the study examined the change in population exposure to the three hazards and their combinations by hazard intensity level at the 1 km 9 1 km grid scale in1982–2015. The results show that population exposures to hypoxia, earthquakes, and snowstorms were about 745 thousand, 97 thousand, and 168 thousand in 2015,respectively, among a total population in Tibet of 3.24 million. These exposures were mainly concentrated in the3400–5000 m above sea level zone. The population exposed to hypoxia and earthquakes showed a rising trend from 1982 to 2015, while the population exposed tosnowstorms decreased after 2000 due to reduced snowstorm intensity. Hypoxia-earthquake and hypoxia-snowstorm are the main multiple hazard combinations that people in Tibet suffered from and their personátime exposures were estimated at around 842 thousand and 913 thousand in 2015, respectively, with an average annual increase of 1.7% and 1.3%. Hypoxia is the most important health risk in Tibet. The areas of high personátime exposure to multiple hazards of hypoxia-earthquake-snowstorm are the key areas for strengthening integrated risk governance. | Anyu Zhang Jingai Wang Yao Jiang Yanqiang Chen Peijun Shi | 2018 | International Journal of Disaster Risk Science2018，9，4： | 3 |
| 3 | AN INNER-FEEDBACK-STYLE TRAVELING-WAVE TUBE OSCILLATOR显示文摘A new concept of inner-feedback-style traveling wave tube oscillator, which is based on a traveling-wave tube having a partial reflector located at near the junction between the slow-wave structure and the output coupler and a mechanical tuner connected to the input coupler, is proposed. Simulations by CHIPIC code show that the inner-feedback-style traveling wave tube oscillator having 100W of power, about 10% of electron efficiency and a tunable band of 73.35-73.91 GHz may be achieved. Compared with Backward Wave Oscillators (BWOs), the new devices have similar ability for tuning, and have much higher electron efficiency, suggesting much more potential as a Terahertz source. | Wang Zicheng Li Haiqiang Xu Anyu Liu Qinglun Liu Wei | 2012 | Journal of Electronics(China)2012，29，6： | 2 |

| 6 | Thermal Runaway of Lithium-Ion Batteries Employing Flame-Retardant Fluorinated Electrolytes显示文摘Fluorinated electrolytes possess good antioxidant capacity that provides high compatibility to high-voltage cathode and flame retardance;thus,they are considered as a promising solution for advanced lithium-ion batteries carrying both high-energy density and high safety.Moreover,the fluorinated electrolytes are widely used to form stable electrolyte interphase,due to their chemical reactivity with lithiated graphite or lithium.However,the influence of this reactivity on the thermal safety of batteries is seldom discussed.Herein,we demonstrate that the flame-retardant fluorinated electrolytes help to reduce the flammability,while the lithium-ion batteries with flame-retardant fluorinated electrolytes still undergo thermal runaway and disclose their different thermal runaway pathway from that of battery with conventional electrolyte.The reduction in fluorinated components(e.g.,LiPF 6 and fluoroethylene carbonate(FEC))by fully lithiated graphite accounts for a significant heat release during battery thermal runaway.The 13%of total heat is sufficient to trigger the chain reactions during battery thermal runaway.This study deepens the understanding of the thermal runaway mechanism of lithium-ion batteries employing flame-retardant fluorinated electrolytes,providing guidance on the concept of electrolyte design for safer lithium-ion batteries. | Junxian Hou Li Wang Xuning Feng Junpei Terada Languang Lu Shigeaki Yamazaki Anyu Su Yoshiko Kuwajima Yongjiang Chen Tomoya Hidaka Xiangming He Hewu Wang Minggao Ouyang | 2023 | Energy & Environmental Materials2023，6，1： | 1 |
| 7 | Dynamic Assessment of Global Maize Exposure to Extremely High Temperatures显示文摘Exposure to extreme heat can severely harm crop growth and development,and it is essential to assess such exposure accurately to minimize risks to crop production.However,the actual distribution of crops and its changes have neither been examined in sufficient detail nor integrated into the assessments of exposure to ensure their accuracy.By examining the distribution of maize at a high resolution through species distribution modeling,we assessed the past and future exposure of maize to temperatures above 37℃worldwide.Such exposure is likely to be widespread and severe,mainly in the subtropics,and may even expand to the mid-latitudes to encompass some major maize-producing areas.Many areas at both high and low latitudes may become exposed for the first time in the next 20 years.By the 2050 s,the total area exposed could increase by up to 185%to 308.18 million ha,of which the area exposed for over 60 days may increase nearly sevenfold.The average length of exposure may increase by 69%to 27 days,and areas optimally suited to maize planting may see the fastest increase by up to 772%.Extreme heat can threaten global maize production severely,and measures to mitigate that threat and to adapt to it are urgently needed. | Yuan Gao Peng Su Anyu Zhang Ran Wang Jing'ai Wang | 2021 | International Journal of Disaster Risk Science2021，12，5： | 1 |

| 18 | The Localized Method of Fundamental Solution for Two Dimensional Signorini Problems显示文摘In this work,the localized method of fundamental solution(LMFS)is extended to Signorini problem.Unlike the traditional fundamental solution(MFS),the LMFS approximates the field quantity at each node by using the field quantities at the adjacent nodes.The idea of the LMFS is similar to the localized domain type method.The fictitious boundary nodes are proposed to impose the boundary condition and governing equations at each node to formulate a sparse matrix.The inequality boundary condition of Signorini problem is solved indirectly by introducing nonlinear complementarity problem function(NCP-function).Numerical examples are carried out to validate the reliability and effectiveness of the LMFS in solving Signorini problems. | Zhuowan Fan Yancheng Liu Anyu Hong Fugang Xu Fuzhang Wang | 2022 | Computer Modeling in Engineering & Sciences2022，，7： | 0 |
| 19 | A generalized synthesis method for freestanding multiferroic twodimensional layered supercell oxide films via a sacrificial buffer layer显示文摘Multiferroics are an intriguing family of materials due to the simultaneous presence of two ferroic orderings,namely,ferroelectricity and ferromagnetism.They are scientifically and technologically important and have numerous potential applications,such as four-state logic memories and multiferroic tunneling junctions.However,the growth of epitaxial singlephase multiferroic thin films typically requires single crystalline oxide substrates,which hinders their future integration with Sibased devices.In this study,we report a generalized synthesis method that uses the polydimethylsiloxane(PDMS)-assisted wetetching method with an Sr_(3)Al_(2)O_(6)(SAO)sacrificial layer to transfer freestanding single-phase multiferroic Bi_(2)NiMnO_(6)(BNMO)films from conventional SrTiO_(3)(STO)substrates onto a Si wafer.The structures and properties of the films have been characterized before and after the transfer.These transferred films possess good multiferroic properties on Si wafers,indicating full compatibility with modern Si technology.This method can be generally applicable to other Bi-based multiferroic materials as well.Lastly,the original STO substrates after the transfer process have been recycled for preparing new batches of freestanding BNMO films,indicating a low-cost and sustainable method for manufacturing large-volume freestanding complex oxide thin films. | Jianan Shen Benson Kunhung Tsai Ke Xu Anyu Shang James PBarnard Yizhi Zhang Rahul Tripathi Zhihong Chen Xinghang Zhang Haiyan Wang | 2023 | Nano Research2023，16，7： | 0 |
| 20 | Sulfurized hematite for photo-Fenton catalysis显示文摘A hematite/amorphous sulfur composite was prepared via simple heating hematite and α-sulfur in Teflon-lined autoclave at low temperature. The composite was characterized by X-ray diffraction(XRD), Raman spectrum,Thermal Gravity Analysis(TGA), Transmission Electron Microscopy(TEM) and X-ray photoelectron spectroscopy(XPS). The results revealed that an allotrope sulfur at 5-37% weight percent was found in the composite.After sulfuration, S_n^(2-) or S_2^(2-) was doped in the lattice of hematite, large amounts of OH and SO_4 were adsorbed on the surface of hematite. Hematite/amorphous sulfur composite had superior photo-Fenton activities than pure hematite. This work also demonstrated that amorphous sulfur also had the activity of photo-Fenton catalysis. OH^-and SO_4 radicals facilitated dye adsorption and acted as a bridge to link H_2 O_2. Moreover, SO_4 radicals on hematite served as electron trapping center that can receive photo-induced electron from conduction band of hematite and transfer it to the adsorbed H_2 O_2, increasing the rate of photo-Fenton reaction eventually. | Yaping Zhang Kaituo Dong Zheng Liu Haolin Wang Shengxiang Ma Anyu Zhang Ming Li Lianqing Yu Yan Li | 2017 | Progress in Natural Science:Materials International2017，27，4： | 0 |
