| 1 | Clinical characteristics of 24 asymptomatic infections with COVID-19 screened among close contacts in Nanjing,China显示文摘Previous studies have showed clinical characteristics of patients with the 2019 novel coronavirus disease(COVID-19)and the evidence of person-to-person transmission.Limited data are available for asymptomatic infections.This study aims to present the clinical characteristics of 24 cases with asymptomatic infection screened from close contacts and to show the transmission potential of asymptomatic COVID-19 virus carriers.Epidemiological investigations were conducted among all close contacts of COVID-19 patients(or suspected patients)in Nanjing,Jiangsu Province,China,from Jan 28 to Feb 9,2020,both in clinic and in community.Asymptomatic carriers were laboratory-confirmed positive for the COVID-19 virus by testing the nucleic acid of the pharyngeal swab samples.Their clinical records,laboratory assessments,and chest CT scans were reviewed.As a result,none of the 24 asymptomatic cases presented any obvious symptoms while nucleic acid screening.Five cases(20.8%)developed symptoms(fever,cough,fatigue,etc.)during hospitalization.Twelve(50.0%)cases showed typical CT images of ground-glass chest and 5(20.8%)presented stripe shadowing in the lungs.The remaining 7(29.2%)cases showed normal CT image and had no symptoms during hospitalization.These 7 cases were younger(median age:14.0 years;P=0.012)than the rest.None of the 24 cases developed severe COVID-19 pneumonia or died.The median communicable period,defined as the interval from the first day of positive nucleic acid tests to the first day of continuous negative tests,was 9.5 days(up to 21 days among the 24 asymptomatic cases).Through epidemiological investigation,we observed a typical asymptomatic transmission to the cohabiting family members,which even caused severe COVID-19 pneumonia.Overall,the asymptomatic carriers identified from close contacts were prone to be mildly ill during hospitalization.However,the communicable period could be up to three weeks and the communicated patients could develop severe illness.These results highlighted the importance of close contact tracing and longitudinally surveillance via virus nucleic acid tests.Further isolation recommendation and continuous nucleic acid tests may also be recommended to the patients discharged. | Zhiliang Hu Ci Song Chuanjun Xu Guangfu Jin Yaling Chen Xin Xu Hongxia Ma Wei Chen Yuan Lin Yishan Zheng Jianming Wang Zhibin Hu Yongxiang Yi Hongbing Shen | 2020 | Science China(Life Sciences)2020，63，5： | 77 |

| 6 | Projected Changes in Temperature and Precipitation Extremes over China as Measured by 50-yr Return Values and Periods Based on a CMIP5 Ensemble显示文摘Future changes in the 50-yr return level for temperature and precipitation extremes over China's Mainland are investigated based on a CMIP5 multi-model ensemble for RCP2.6, RCP4.5 and RCP8.5 scenarios. The following indices are analyzed:TXx and TNn(the annual maximum and minimum of daily maximum and minimum surface temperature), RX5 day(the annual maximum consecutive 5-day precipitation) and CDD(maximum annual number of consecutive dry days). After first validating the model performance, future changes in the 50-yr return values and return periods for these indices are investigated along with the inter-model spread. Multi-model median changes show an increase in the 50-yr return values of TXx and a decrease for TNn, more specifically, by the end of the 21 st century under RCP8.5, the present day 50-yr return period of warm events is reduced to 1.2 yr, while extreme cold events over the country are projected to essentially disappear.A general increase in RX5 day 50-yr return values is found in the future. By the end of the 21 st century under RCP8.5, events of the present RX5 day 50-yr return period are projected to reduce to < 10 yr over most of China. Changes in CDD-50 show a dipole pattern over China, with a decrease in the values and longer return periods in the north, and vice versa in the south. Our study also highlights the need for further improvements in the representation of extreme events in climate models to assess the future risks and engineering design related to large-scale infrastructure in China. | Ying XU Xuejie GAO Filippo GIORGI Botao ZHOU Ying SHI Jie WU Yongxiang ZHANG | 2018 | Advances in Atmospheric Sciences2018，35，4： | 11 |

| 8 | Ni-Co/Mg-Al catalyst derived from hydrotalcite-like compound prepared by plasma for dry reforming of methane显示文摘Ni-Co bimetallic catalysts with different Ni/Co content were derived from cold plasma jet decomposition and reduction of hydrotalcite-like compounds containing Ni,Co,Mg and Al,and their catalytic performance was investigated with dry reforming of methane.Experimental results showed that the hydrotalcite-like precursors could be completely decomposed and partly reduced by cold plasma jet,and the Nicontained catalysts exhibited much higher activity than the catalyst without Ni.Especially,the catalyst with Ni/Co ratio of 8/2 achieved not only the highest conversions of 80.3%and 69.3%for CH4 and CO2,respectively,but also the best stability in 100 h testing.The catalysts were characterized by XRD,XPS,TEM and N2 adsorption techniques,and the results showed that the better performance of the 8Ni2Co bimetallic catalyst was attributed to its higher metal dispersion,smaller metal particle size,as well as the interaction effect between Ni and Co,which were brought by the special catalyst preparation method. | Huali Long Yan Xu Xiaoqing Zhang Shijing Hu Shuyong Shang Yongxiang Yin Xiaoyan Dai | 2013 | Journal of Energy Chemistry2013，22，5： | 8 |
| 9 | Trial of small gateroad pillar in top coal caving longwall mining of large mining height显示文摘Coal seams in Tashan Mine of Datong Coal Group in China average 15 m thick and have been mined by the top coal caving longwall mining method of large mining height. Mining height was 3.8 m and the top coal caving height was 11.2 m. The gateroad pillar between panels was 38 m. During retreat mining,serious bumps occurred in the gateroads on both sides of the pillar affecting safety production. Therefore,pillarless mining was experimented. Using numerical modeling and comparative study of cases of similar mining condition,it was decided to employ a 6 m wide pillar,rather than the previous 38 m wide pillar.Support system for the gateroads was designed and implemented. During gateroad development,pillar failure conditions and entry deformation were monitored. Hydraulic fracturing method was employed to cut off the K3 sandstone along the entry rib so as to reduce the abutment pressure induced during retreat mining. Support reinforcement method combining grouting and advanced reinforcement methods was proposed to insure stable gateroad ahead of mining. Methane drainage and nitrogen injection were implemented to eliminate hazards associated with mine fire and spontaneous combustion. Since the development of gateroad has just completed,and retreat mining has not begun,the effectiveness of the proposed methods is unknown at this point. However,monitoring will continue until after mining.The results will be published in a separate paper. | Li Huamin Syd Peng Li Huigui Xu Yongxiang Yuan Ruifu Yue Shuaishuai Li Kun | 2016 | International Journal of Mining Science and Technology2016，26，1： | 8 |
| 10 | Effects of Shuanghuanglian oral liquids on patients with COVID-19:a randomized,open-label,parallel-controlled,multicenter clinical trial显示文摘We conducted a randomized,open-label,parallel-controlled,multicenter trial on the use of Shuanghuanglian(SHL),a traditional Chinese patent medicine,in treating cases of COVID-19.A total of 176 patients received SHL by three doses(56 in low dose,61 in middle dose,and 59 in high dose)in addition to standard care.The control group was composed of 59 patients who received standard therapy alone.Treatment with SHL was not associated with a difference from standard care in the time to disease recovery.Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group(93.4%vs.73.9%,P=0.006).Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia,which was evaluated by density reduction of inflammatory focus from baseline,at day 7(mean difference(95%CI),−46.39(−86.83 to−5.94)HU;P=0.025)and day 14(mean difference(95%CI),−74.21(−133.35 to−15.08)HU;P=0.014).No serious adverse events occurred in the SHL groups.This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19. | Li Ni Zheng Wen Xiaowen Hu Wei Tang Haisheng Wang Ling Zhou Lujin Wu Hong Wang Chang Xu Xizhen Xu Zhichao Xiao Zongzhe Li Chene Li Yujian Liu Jialin Duan Chen Chen Dan Li Runhua Zhang Jinliang Li Yongxiang Yi Wei Huang Yanyan Chen Jianping Zhao Jianping Zuo Jianping Weng Hualiang Jiang Dao Wen Wang | 2021 | Frontiers of Medicine2021，15，5： | 7 |
| 11 | Permanent Magnet Shape Optimization Method for PMSM Air Gap Flux Density Harmonics Reduction显示文摘This paper proposed a permanent magnet optimization method to suppress the air gap flux density harmonic of permanent magnet synchronous motor(PMSM).The method corrected the effective air gap length of the motor,calculated the magnetization length of the permanent in the case of parallel magnetization,and took the influence of the permanent magnet relative permeability into consideration.Based on these works,for a given sinusoidal air gap flux density waveform,the corresponding structural parameters can be calculated,so as to achieve the optimization of the permanent magnet.By using this method to optimize the shape of the magnet,the fundamental wave of the air gap flux density can be retained to the greatest extent,so as to eliminate harmonics and maintain the output capacity at the same time.The feasibility and accuracy of the method have been verified by finite element analysis(FEA)and prototype machine experiment.This method is simple and time-saving,and has a satisfactory accuracy,which provides a reference method for permanent magnet optimization of PMSM. | Chengsi Liu Yongxiang Xu Jibin Zou Guodong Yu Liang Zhuo | 2021 | CES Transactions on Electrical Machines and Systems2021，5，4： | 4 |
| 12 | Reduction of High-frequency Vibration Noise for Dual-branch Three-phase Permanent Magnet Synchronous Motors显示文摘Two-level voltage source inverters with pulse width modulation(PWM)generate multiple carrier harmonics,thereby exciting high-frequency noise from the motor.Based on a special dual-branch three-phase permanent magnet synchronous motor(PMSM),a method that utilizes a known modified space vector PWM technique is proposed.This method is able to suppress unpleasant high-frequency vibration noise as well as acoustic noise more effectively than other methods.Vibration noise near the twice carrier frequency is eliminated,and PWM vibration noise around the carrier frequency is also reduced.In particular,vibration and acoustic noise at the twice carrier frequency are eliminated using a carrier phase-shift of 0.5πand the special winding structure of the dual-branch PMSM.The effectiveness of the proposed method is confirmed using detailed experimental results. | Wentao Zhang Yongxiang Xu Yingliang Huang Jibin Zou | 2020 | Chinese Journal of Electrical Engineering2020，6，2： | 4 |
| 13 | Process-based modeling analyses of Sabina przewalskii growth response to climate factors around the northeastern Qaidam Basin显示文摘Sabina przewalskii is the longest living endemic tree species in the northeastern Tibetan Plateau,and has been widely employed in tree ring based climate research in China.However,most dendroclimatic reconstructions have been primarily based on empirical relationships between tree growth and climate factors identified by statistical assessment.To date,the physiological relationships between tree growth and their limiting climate factors have not been properly assessed.Here,we simulated the physiological response of Sabina przewalskii tree growth to major limiting climate factors based on the Vaganov-Shashkin (VS) model.The VS modeled results validated the relationships between tree ring and climate factors constructed by statistical models,both approaches suggesting that precipitation during the early growing season,especially in May and June,has significant effect on tree growth,while temperature mainly affects tree growth by warming-induced drought and by extending the growing season.Under current and projected climate scenarios,our modeling results predict an increase in radial growth of Sabina przewalskii around the Qaidam Basin,with the potential outcome that regional forests will increase their capacity to sequester carbon. | ZHANG YongXiang SHAO XueMei XU Yan WILMKING Martin | 2011 | Chinese Science Bulletin2011，56，14： | 4 |

| 15 | Ni/MgO catalyst prepared using atmospheric high-frequency discharge plasma for CO_2 reforming of methane显示文摘A new type of Ni/MgO catalyst was prepared using atmospheric high-frequency discharge cold plasma. The influences of conventional method, plasma method, and plasma plus calcination method on the catalytic activity were studied and the CO2 reforming of methane was chosen as the probe reaction. The catalysts were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), X-ray photoelectron spectroscopy, and CO2 temperature-programmed surface reaction techniques. The results suggested that the nickel-based catalyst prepared by plasma plus calcination method possessed a smaller particle size and a higher dispersion of active component, better low-temperature activity and enhanced anti-coking ability. The conversion of CO2 and CH4 was 90.70% and 89.37%, respectively, and the reaction lasted for 36 h without obvious deactivation under 101.325 kPa and 750°C with CO2/CH4 = 1/1. | Pan Qin Huiyuan Xu Huali Long Yi Ran Shuyong Shang Yongxiang Yin Xiaoyan Dai | 2011 | Journal of Natural Gas Chemistry2011，20，5： | 3 |

| 19 | Survey of Safety Management Approaches to Unmanned Aerial Vehicles and Enabling Technologies显示文摘Unmanned aerial vehicle(UAV)has a rapid development over the last decade.However,an increasing number of severe flight collision events caused by explosive growth of UAV have drawn widespread concern.It is an important issue to investigate safety management approaches of UAVs to ensure safe and efficient operation.In this paper,we present a comprehensive overview of safety management approaches in large,middle and small scales.In large-scale safety management,path-planning problem is a crucial issue to ensure safety and ordered operation of UAVs globally.In middle-scale safety management,it is an important issue to study the conflict detection and resolution methods.And in small-scale safety management,real-time collision avoidance is the last line of ensuring safety.Moreover,a UAV can be regarded as a terminal device connected through communication and information network.Therefore,the enabling technologies,such as sensing,command and control communication,and collaborative decision-making control technology,have been studied in the last. | Xuejun Zhang Yanshuang Du Bo Gu Guoqiang Xu Yongxiang Xia | 2018 | Journal of Communications and Information Networks2018，3，4： | 1 |
| 20 | Photocrosslinkable Col/PCL/Mg composite membrane providing spatiotemporal maintenance and positive osteogenetic effects during guided bone regeneration显示文摘Guided bone regeneration membranes have been effectively applied in oral implantology to repair bone defects.However,typical resorbable membranes composed of collagen(Col)have insufficient mechanical properties and high degradation rate,while non-resorbable membranes need secondary surgery.Herein,we designed a photocrosslinkable collagen/polycaprolactone methacryloyl/magnesium(Col/PCLMA/Mg)composite membrane that provided spatiotemporal support effect after photocrosslinking.Magnesium particles were added to the PCLMA solution and Col/PCLMA and Col/PCLMA/Mg membranes were developed;Col membranes and PCL membranes were used as controls.After photocrosslinking,an interpenetrating polymer network was observed by scanning electron microscopy(SEM)in Col/PCL and Col/PCL/Mg membranes.The elastic modulus,swelling behavior,cytotoxicity,cell attachment,and cell proliferation of the membranes were evaluated.Degradation behavior in vivo and in vitro was monitored according to mass change and by SEM.The membranes were implanted into calvarial bone defects of rats for 8 weeks.The Col/PCL and Col/PCL/Mg membranes displayed much higher elastic modulus(p<0.05),and a lower swelling rate(p<0.05),than Col membranes,and there were no differences in cell biocompatibility among groups(p>0.05).The Col/PCL and Col/PCL/Mg membranes had lower degradation rates than the Col membranes,both in vivo and in vitro(p<0.05).The Col/PCL/Mg groups showed enhanced osteogenic capability compared with the Col groups at week 8(p<0.05).The Col/PCL/Mg composite membrane represents a new strategy to display space maintenance and enhance osteogenic potential,which meets clinical needs. | Feilong Wang Dandan Xia Siyi Wang Ranli Gu Fan Yang Xiao Zhao Xuenan Liu Yuan Zhu Hao Liu Yongxiang Xu Yunsong Liu Yongsheng Zhou | 2022 | Bioactive Materials2022，7，7： | 1 |
