1Preliminary results pertaining to coseismic displacement and preseismic strain accumulation of the Lushan M_S7.0 earthquake,as reflected by GPS surveying显示文摘This paper presents the coseismic displacement and preseismic deformation fields of the Lushan MS7.0 earthquake that occurred on April 20,2013.The results are based on GPS observations along the Longmenshan fault and within its vicinity.The coseismic displacement and preseismic GPS results indicate that in the strain release of this earthquake,the thrust rupture is dominant and the laevorotation movement is secondary.Furthermore,we infer that any possible the rupture does not reach the earth’s surface,and the seismogenic fault is most likely one fault to the east of the Guanxian-Anxian fault.Some detailed results are obtainable.(1)The southern segment of the Longmenshan fault is locked preceding the Lushan earthquake.After the Wenchuan earthquake,the strain accumulation rate in the southeast direction accelerates in the epicenter of the Lushan earthquake,and the angle between the principal compressional strain and the seismogenic fault indicates that a sinistral deformation background in the direction of the seismogenic fault precedes the Lushan earthquake.Therefore,it is evident that the Wenchuan MS8.0 earthquake accelerated the pregnancy of the Lushan earthquake.(2)The coseismic displacements reflected by GPS data are mainly located in a region that is 230 km(NW direction)×100 km(SW direction),and coseismic displacements larger than 10 mm lie predominantly in a100-km region(NW direction).(3)On a large scale,the coseismic displacement shows thrust characteristics,but the associated values are remarkably small in the near field(within 70 km)of the earthquake fault.Meanwhile,the thrust movement in this70-km region does not correspond with the attenuation characteristics of the strain release,indicating that the rupture of this earthquake does not reach the earth’s surface.(4)The laevorotation movements are remarkable in the 50-km region,which is located in the hanging wall that is close to the earthquake fault,and the corresponding values in this case correlate with the attenuation characteristics of the strain release.WU YanQiang JIANG ZaiSen WANG Min CHE Shi LIAO Hua LI Qiang LI Peng YANG YongLin XIANG HePing SHAO ZhiGang WANG WuXing WEI WenXin LIU XiaoXia 2013Chinese Science Bulletin2013,58,28:33
2Observation and analysis of near-surface atmospheric aerosol optical properties in urban Beijing显示文摘Year-round measurements of the mass concentration and optical properties of fine aerosols(PM_(2.5)) from June 2009 to May 2010 at an urban site in Beijing were analyzed.The annual mean values of the PM_(2.5) mass concentration,absorption coefficient(Ab),scattering coefficient(Sc) and single scattering albedo(SSA)at 525 nm were 67±66μg/m^3,64 ±62 Mm^(-1),360 ±405 Mm^(-1) and 0.82 ±0.09,respectively.The bulk mass absorption efficiency and scattering efficiency of the PM_(2.5) at 525 nm were 0.78 m^2/g and 5.55 m^2/g,respectively.The Ab and Sc showed a similar diurnal variation with a maximum at night and a minimum in the afternoon,whereas SSA displayed an opposite diurnal pattern.Significant increases in the Ab and Sc were observed in pollution episodes caused by the accumulation of pollutants from both local and regional sources under unfavorable weather conditions.Aerosol loadings in dust events increased by several times in the spring,which had limited effects on the Ab and Sc due to the low absorption and scattering efficiency of dust particles.The frequency of haze days was the highest in autumn because of the high aerosol absorption and scattering under unfavorable weather conditions.The daily PM_(2.5)concentration should be controlled to a level lower than 64 μg/m^3 to prevent the occurrence of haze days according to its exponentially decreased relationship with visibility.Junshan Jing Yunfei Wu Jun Tao Huizheng Che Xiangao Xia Xiaochun Zhang Peng Yan Deming Zhao Leiming Zhang 2015Particuology2015,13,1:16
3Comparative Analysis of Nutrient Composition of Caulerpa lentillifera from Different Regions显示文摘This study investigated the difference of nutrient composition in Caulerpa lentillifera collected from different regions.The nutrient compositions of C.lentillifera from China's Hainan and Shandong provinces were determined and compared with those from Semporna(Malaysia),Sabah(Malaysia),Petchburi(Thailand),and two other species of seaweeds(Malaysia).The results showed that the polysaccharide and protein contents of C.lentillifera from Hainan(44.82%±0.98%and 12.5%±0.70%),Shandong(43.22%±1.42%and 14.7%±0.72%),Petchburi(59.27%±2.31%and 12.49%±0.30%),and Sabah(44.02%±2.01%and 19.38%±1.48%)were higher than those of Eucheuma cottonii(26.49%±3.01%and 9.76%±1.33%)and Sargassum polycystum(33.49%±1.70%and 5.40%±0.07%),respectively.The polyunsaturated fatty acid contents in C.lentillifera from Hainan(29.98%)and Shandong(22.11%)were higher than that in Semporna(16.76%±0.27%),Sabah(9.49%),and S.polycystum(20.34%±0.43%),but lower than that in E.cottonii(51.55%±0.57%).In Caulerpa lentillifera of Hainan and Shandong provinces,the essential amino acid(EAA)/total amino acid(TAA)ratios were 35.22%and 38.78%,respectively;and the EAA/ETAA ratios were 54.36%and 63.35%,respectively.The EAA composition of C.lentillifera was close to the ideal model of Food and Agriculture Organization/World Health Organization.C.lentillifera was rich in mineral elements,including calcium((3315.85±127.55)mg(100 g)^-1 and(3728.35±92.38)mg(100 g)^-1),magnesium((6715.74±82.58)mg(100 g)^-1 and(8128.59±242.72)mg(100 g)^-1),and trace elements,including iron((510.65±5.47)mg(100 g)^-1 and(1972.97±183.35)mg(100 g)^-1),selenium((1.04±0.08)mg(100 g)^-1 and(0.83±0.15)mg(100 g)^-1),and zinc((33.90±0.13)mg(100 g)^-1 and(11.75±2.05)mg(100 g)^-1).These results showed that C.lentillifera was more nutritious than S.polycystum or E.cottonii in terms of polysaccharide,protein,and fatty acid contents.Furthermore,both C.lentillifera species collected from Hainan and Shandong provinces show more basic nutrients.Therefore,C.lentillifera has important development and application prospects.ZHANG Meijian MA Yurong CHE Xinyi HUANG Zumei CHEN Peng XIA Guanghua ZHAO Meihui 2020Journal of Ocean University of China2020,19,2:8
4Effects of dietary supplementation with essential oils and protease on growth performance,antioxidation,inflammation and intestinal function of weaned pigs显示文摘This experiment evaluated the impacts of essential oils(EO)and protease(PRO),independently or in combination,on growth performance,antioxidation,inflammation and intestinal function of weaned pigs.One hundred and sixty weaned pigs(21 d of age,BW of 6.74±0.20 kg)were randomly divided into 4 treatments with 8 replicate pens of 5 pigs per pen.Dietary treatments included the following:1)control diet(CON),2)CON with 300 mg/kg essential oils(EO),3)CON with 500 mg/kg protease(PRO),4)CON with 300 mg/kg essential oil and 500 mg/kg protease(EO + PRO).On d 8,one pig from each penwas selected for sampling.The remaining pigs were fed for an additional week and growth performance was monitored during this period.Dietary treatments had no marked effects(P>0.05)on the growth performance of pigs.However,pigs receiving EO diet had higher(P<0.05)serumglutathione peroxidase(GSH-Px)activity,and tended to decrease(P=0.063)serum concentration of tumor necrosis factor-a(TNF-a).In addition,pigs receiving EO diet had higher(P<0.05)abundances of phylum Actinobacteria,and genera Bifidobacterium,and lower(P<0.05)phylum Bacteroidetes and genera Alloprevotella in colonic digesta.Pigs receiving PRO diet decreased(P<0.05)the serum concentration of malondialdehyde(MDA)and diamine oxidase activity,increased(P<0.05)the villus height and the ratio of villus height to crypt depth in duodenum,increased sucrase activity in jejunal mucosa,and also increased the abundance of phylum Actinobacteria in colonic digesta.Furthermore,the synergistic effects of EO and PROwas observed(P<0.05)for pigs with decreasing serum TNF-a concentration and increasing serum GSH-Px activity.Collectively,the results indicated that dietary supplementation of EO and PRO had no significant effects on growth performance of weaned pigs.EO diet appeared to improve antioxidant activity and intestinal microbiota,while PRO diet improved intestinal morphology and digestive enzyme activity,and there was a synergistic effect of EO and PRO on reducing inflammatory parameters in weaned pigs.Xie Peng Qiang Zhou Cheng Wu Jian Zhao Quan Tan Ying He Liang Hu Zhengfeng Fang Yan Lin Shengyu Xu Bin Feng Jian Li Yong Zhuo Chris Van Ginneken Xuemei Jiang De Wu Lianqiang Che 2022Animal Nutrition2022,,2:8
5Natatanuran frogs used the Indian Plate to step-stone disperse and radiate across the Indian Ocean显示文摘Investigating the evolutionary history of widespread higher taxa, subjected to multiple tectonic events, can provide evidence for or against various palaeogeographical models of early Earth history (1,2)Contemporary biotic distributions have been strongly influenced by events associated with the breakup of Gondwana into present-day Africa,Antarctica, Australia, South America,Madagascar and India, during the Late Mesozoic and Early Palaeogene (2)The fragmentation of Gondwana and subsequent tectonic drift ultimately allowed biotic exchanges between Laurasia and Gondwana [2,3], influencing the global distributions of many taxa.Zhi-Yong Yuan Bao-Lin Zhang Christopher J.Raxworthy David W.Weisrock Paul M.Hime Jie-Qiong Jin Emily M.Lemmon Alan R.Lemmon Sean D.Holland Michelle L.Kortyna Wei-Wei Zhou Min-Sheng Peng Jing Che Elizabeth Prendini 2019National Science Review2019,6,1:5
6Expression of indoleamine 2,3-dioxygenase in a murine model of Aspergillus fumigatus keratitis显示文摘AIM: To observe the presence and expression of indoleamine 2,3-dioxygenase(IDO) during the corneal immunity to Aspergillus fumigatus(A. fumigatus) in the murine models.·METHODS: The murine model of fungal keratitis was established by smearing with colonies of A. fumigatus after scraping central epithelium of cornea and covering with contact lenses in C57BL/6 mice. The mice were randomly divided into control group, sham group and A.fumigatus keratitis group. The cornea was monitored daily using a slit lamp and recorded disease score after infection. Corneal lesion was detected by immunofluorescence staining. IDO m RNA and protein were also detected by quantitative reverse transcription-polymerase chain reaction(q RT-PCR) and Western blot.· RESULTS: The disease score and slit lamp photography indicated that disease severity was consistent with corneal inflammation in the murine models, and the disease scores in A. fumigatus keratitis group were obviously higher than those in the sham group. By immunofluorescence staining, IDO was mainly localized in corneal epithelium and stroma in the murine corneal tissues with A. fumigatus keratitis. Compared with the sham group, IDO m RNA expression was significantly enhanced in corneal epithelium infected by A. fumigatus. Furthermore, IDO protein expression detected by Western blot was in accord with transcript levels of IDO m RNA measured by q RT-PCR. IDO protein expression was enhanced after A. fumigatus infection compared with the sham group.·CONCLUSION: IDO is detected in corneal epithelium and stroma locally, which indicates IDO takes part in the pathogenesis of A. fumigatus keratitis and plays a key role in immune regulation at the early stage.Nan Jiang Gui-Qiu Zhao Jing Lin Li-Ting Hu Cheng-Ye Che Cui Li Qian Wang Qiang Xu Jie Zhang Xu-Dong Peng 2016International Journal of Ophthalmology(English edition)2016,9,4:4

8Applying the WRF Double-Moment Six-Class Microphysics Scheme in the GRAPES_Meso Model: A Case Study显示文摘This study incorporated the Weather Research and Forecasting(WRF) model double-moment 6-class(WDM6) microphysics scheme into the mesoscale version of the Global/Regional Assimilation and Pr Ediction System(GRAPES_Meso). A rainfall event that occurred during 3–5 June 2015 around Beijing was simulated by using the WDM6, the WRF single-moment 6-class scheme(WSM6), and the NCEP 5-class scheme, respectively. The results show that both the distribution and magnitude of the rainfall simulated with WDM6 were more consistent with the observation. Compared with WDM6, WSM6 simulated larger cloud liquid water content, which provided more water vapor for graupel growth, leading to increased precipitation in the cold-rain processes. For areas with the warmrain processes, the sensitivity experiments using WDM6 showed that an increase in cloud condensation nuclei(CCN)number concentration led to enhanced CCN activation ratio and larger cloud droplet number concentration(Nc) but decreased cloud droplet effective diameter. The formation of more small-size cloud droplets resulted in a decrease in raindrop number concentration(Nr), inhibiting the warm-rain processes, thus gradually decreasing the amount of precipitation. For areas mainly with the cold-rain processes, the overall amount of precipitation increased; however, it gradually decreased when the CCN number concentration reached a certain magnitude. Hence, the effect of CCN number concentration on precipitation exhibits significant differences in different rainfall areas of the same precipitation event.Meng ZHANG Hong WANG Xiaoye ZHANG Yue PENG Huizheng CHE 2018Journal of Meteorological Research2018,32,2:3
9Parthenolide inhibits the proliferation and induces the apoptosis of human uveal melanoma cells显示文摘AIM: To explore the effect of parthenolide(PTL) on human uveal melanoma(UM) cells(C918 and SP6.5 cells) and its molecular mechanism. METHODS: Carboxyfluorescein succinimidyl amino ester(CFSE) assays and cell counting kit-8(CCK-8) were performed to detect the cell viability. Flow cytometry was used to analyze cell cycle and apoptosis. Quantitative realtime polymerase chain reaction(qRT-PCR) and Western blot assays were performed to measure proliferation-related and apoptosis-related factors.RESULTS: Firstly, PTL decreased the viability of C918 and SP6.5 cells in a dose-dependent manner, and the effect of PTL on C918 cells was stronger than on SP6.5;however, it did not affect normal cells. Secondly, PTL increased the proportion of cell number at cell cycle G1 phase in C918 cells, and decreased the proportion of cell number at S phase, but the proportion did not change at G2 phase. In addition, PTL induced the apoptosis of C918 cells, and decreased the expressions of Cyclin D1, B-cell lymphoma-2(Bcl-2) and B-cell lymphoma-extra large(Bcl-XL). Also, PTL increased Cyclin inhibition protein 1(P21), Bcl-2-associated X protein(Bax), Cysteinyl aspartate specific proteinas-3(Caspase-3) and Caspase-9 expression. However, the expression of Caspase-8 was not changed. CONCLUSION: PTL inhibites proliferation and induces apoptosis in UM cells by arresting G1 phase and regulating mitochondrial pathway, however, it does not affect normal cells.Song-Tian Che Li Bie Xu Li Hui Qi Peng Yu Ling Zuo 2019International Journal of Ophthalmology(English edition)2019,12,10:3
10Impact of B-mode-ultrasound-guided transhepatic and transperitoneal cholecystostomy tube placement on laparoscopic cholecystectomy显示文摘BACKGROUND B-mode-ultrasound-guided percutaneous cholecystostomy(PC)may be performed by a transhepatic or transperitoneal approach,called percutaneous transhepatic gallbladder drainage(PHGD)and percutaneous transperitoneal gallbladder drainage(PPGD),respectively.We compared the impact of PC related to the route of catheter placement on subsequent laparoscopic cholecystectomy(LC).AIM To compare the impact of PC related to the route of catheter placement on subsequent LC.METHODS We retrospectively studied 103 patients with acute calculous cholecystitis who underwent scheduled LC after PC between January 2010 and January 2019.Group I included 58 patients who underwent scheduled LC after PHGD.Group II included 45 patients who underwent scheduled LC after PPGD.Clinical outcomes were analyzed according to each group.RESULTS Baseline demographic characteristics did not differ significantly between both groups(P>0.05).Both PHGD and PPGD were able to quickly resolve cholecystitis sepsis.Group I showed significantly higher efficacy than group II in terms of lower pain score during puncture(3.1 vs 4.5;P=0.001)and at 12 h follow-up(1.5 vs 2.2;P=0.001),lower rate of fever within 24 h after PC(13.8%vs 42.2%;P=0.001),shorted operation duration(118.3 vs 139.6 min;P=0.001),lower amount of intraoperative bleeding(72.1 vs 109.4 mL;P=0.001)and shorter length of hospital stay(14.3 d vs 18.0 d;P=0.001).However,group II had significantly lower rate of local bleeding at the PC site(2.2%vs 20.7%;P=0.005)and lower rate of severe adhesion(33.5%vs 55.2%;P=0.048).No significant differences were noted between both groups regarding the conversion rate to laparotomy,rate of subtotal cholecystectomy,complications and pathology.CONCLUSION B-mode-ultrasound-guided PHGD is superior to PPGD followed by LC for treatment of acute calculous cholecystitis,with shorter operating time,minimal amount of intraoperative bleeding and short length of hospital stay.Peng Liu Che Liu Yin-Tao Wu Jian-Yong Zhu Wen-Chao Zhao Jing-Bo Li Hong Zhang Ying-Xiang Yang 2020World Journal of Gastroenterology2020,26,36:3
11Conductive photo-thermal responsive bifunctional hydrogel system with self-actuating and self-monitoring abilities显示文摘Despite enormous efforts in actuators,most researches are only limited to various actuation behaviors and demonstrations of soft materials.It has not yet been reported to capture and monitor its movement status in an invisible environment.Therefore,it is of great significance to develop a self-sensing and self-actuating dual-function hydrogel actuator system to realize real-time monitoring.Here,we report a bifunctional hydrogel system with self-actuating and self-monitoring abilities,which combines the functions of photothermal actuation and electrical resistance sensing into a single material.The bilayer tough conductive hydrogel synthesized by unconventional complementary concentration recombination and cryogenic freezing technique presents a dense conductive network and high-porosity structure,achieving high toughness at 190.3 kPa of tensile strength,high stretchability(164.3%strain),and the toughness dramatically(1,471.4 kJ·m^(−3)).The working mechanism of the monitoring and self-sensing system is accomplished through the integrated monitoring device of surface temperature–bending angle–electron current,to solve the problem of not apperceiving actuator motion state when encountering obstacles in an invisible environment.We demonstrated for the first time a photothermal actuator’s motion of a football player and goalkeeper to finish the penalty and a soft actuator hand,which can achieve the action of sticking to grab and release under photo-thermal actuation.When connected to the control closed circuit,the actuator realized closed-loop monitoring and sensing feedback.The development of bifunctional hydrogel systems may bring new opportunities and ideas in the fields of material science,circuit technology,sensors,and mechanical engineering.Neng Chen Yang Zhou Yinping Liu Yuanyuan Mi Sisi Zhao Wang Yang Sai Che Hongchen liu FengJiang Chen Chong Xu Guang Ma Xue Peng Yongfeng Li 2022Nano Research2022,15,8:3
12Mincle in the innate immune response of mice fungal keratitis显示文摘AIM: To investigate how macrophage inducible C-type lectin(Mincle) influences inflammation in mice fungal keratitis induced by Aspergillus fumigatus(A. fumigatus).METHODS: C57 BL/6 mice were infected with A. fumigatus after pretreated with Mincle agonist TDB or Mincle neutralizing antibody(MincleAb), taking DMSO or IgG as control group respectively. The cornea lesions were monitored with slit-lamp microscope and evaluated by clinical score. Mincle expression was assessed using reverse transcriptionploymerase chain reaction(RT-PCR) and immunostaining. The expression of cytokines(IL-1β, TNF-α and IL-6) chemokines(CXCL-1 and MIP-2) was determined by RTPCR and ELISA. Neutrophil infiltration was observed by immunostaining. The levels of nitric oxide(NO) generated by corneas were tested by Griess reaction. RESULTS: Mincle mRNA and protein levels were higher in infected corneas than normal corneas of C57 BL/6 mice, saving clinical scores revealed differences. When pretreated with Mincle agonist TDB, the mRNA and protein levels of IL-1β, TNF-α and IL-6 in infected corneas were significantly increased compared with the control group(P<0.01). Results of the counterpart in corneas pretreated with Mincle neutralizing antibody was decreased consistently(P<0.01). Expression of CXCL1 and MIP-2 mRNA levels were upregulated in TDB group and down-regulated in Mincle Ab group(P<0.01), coincide with neutrophil aggregation degree in corneas showed by immunostaining. As for the concentration of NO, it was promoted in TDB group compared with DMSO control group, and decreased in Mincle Ab group compared with Ig G control group.CONCLUSION: Mincle plays a dual role in mice fungal keratitis. It participates in the innate immune system by enhancing inflammation. What's more, Mincle can mediate cytotoxic effects by regulating the formation of NO.Guo-Rong Yu Jing Lin Jie Zhang Cheng-Ye Che Xu-Dong Peng Cui Li Li-Ting Hu Guo-Qiang Zhu Kun He Gui-Qiu Zhao 2018International Journal of Ophthalmology(English edition)2018,11,4:3
13Azvudine is a thymus-homing anti-SARS-CoV-2 drug effective in treating COVID-19 patients显示文摘Azvudine(FNC)is a nucleoside analog that inhibits HIV-1 RNA-dependent RNA polymerase(RdRp).Recently,we discovered FNC an agent against SARS-CoV-2,and have taken it into Phase III trial for COVID-19 patients.FNC monophosphate analog inhibited SARS-CoV-2 and HCoV-OC43 coronavirus with an EC_(50) between 1.2 and 4.3 μM,depending on viruses or cells,and selective index(SI)in 15-83 range.Oral administration of FNC in rats revealed a substantial thymus-homing feature,with FNC triphosphate(the active form)concentrated in the thymus and peripheral blood mononuclear cells(PBMC).Treating SARS-CoV-2 infected rhesus macaques with FNC(0.07 mg/kg, qd,orally)reduced viral load,recuperated the thymus,improved lymphocyte profiles,alleviated in flammation and orga n damage,and lessened grou nd・glass opacities in chest X-ray.Sin gle-cell seque ncing suggested the promotion of thymus function by FNC.A randomized,single-arm clinical trial of FNC on compassionate use(n=31)showed that oral FNC(5 mg,qd)cured all COVID-19 patients,with 100%viral ribonucleic acid negative conversion in 3.29±2.22 days(range:1-9 days)and 100%hospital discharge rate in 9.00±4.93 days(range:2-25 days).The side-effect of FNC is minor and transient dizziness and nausea in 16.12%(5/31)patients.Thus,FNC might cure COVID-19 through its anti-SARS-CoV-2 activity concentrated in the thymus,followed by promoted immunity.Jin-Lan Zhang Yu-Huan Li Lu-Lu Wang Hong-Qi Liu Shuai-Yao Lu Yong Liu Ke Li Bin Liu Su-Yun Li Feng-Min Shao Kun Wang Ning Sheng Rui Li Jin-Jin Cui Pei-Chun Sun Chun-Xia Ma Bo Zhu Zhe Wang Yuan-Hao Wan Shi-Shan Yu Yongsheng Che Chao-Yang Wang Chen Wang Qiangqian Zhang Li-Min Zhao Xiao-Zhong Peng Zhenshun Cheng Jun-Biao Chang Jian-Dong Jiang 2022Signal Transduction and Targeted Therapy2022,7,1:3

15CD23 mediated the induction of pro-inflammatory cytokines Interleukin-1 beta and tumor necrosis factors-alpha in Aspergillus fumigatus keratitis显示文摘To the Editor:Fungal keratitis is primarily caused by pathogenic fungi species,such as Fusarium solani and Aspergillus fumigatus.The incidence of A.fumigatus has been increased worldwide.[1]Although new therapies have been used for fungal keratitis,the efficacy of antifungal drugs remains unsatisfactory at present.[2]Fungal keratitis is still a challenge for ophthalmologists because of its difficult and delayed diagnosis,as well as the lack of effective drugs and treatment.Hai-Jing Yan Nan Jiang Li-Ting Hu Qiang Xu Xu-Dong Peng Hua Yang Wen-Yi Zhao Le-Yu Lyu Li-Mei Wang Cheng-Ye Che 2021Chinese Medical Journal2021,,8:2
16Comparison of Submicron Particles at a Rural and an Urban Site in the North China Plain during the December 2016 Heavy Pollution Episodes显示文摘An extensive field experiment for measurement of physical and chemical properties of aerosols was conducted at an urban site in the Chinese Academy of Meteorological Sciences(CAMS) in Beijing and at a rural site in Gucheng(GC), Hebei Province in December 2016. This paper compares the number size distribution of submicron particle matter(PM1, diameter < 1 μm) between the two sites. The results show that the mean PM1 number concentration at GC was twice that at CAMS, and the mass concentration was three times the amount at CAMS. It is found that the accumulation mode(100–850 nm) particles constituted the largest fraction of PM1 at GC, which was significantly correlated with the local coal combustion, as confirmed by a significant relationship between the accumulation mode and the absorption coefficient of soot particles. The high PM1 concentration at GC prevented the occurrence of new particle formation(NPF) events, while eight such events were observed at CAMS. During the NPF events, the mass fraction of sulfate increased significantly, indicating that sulfate played an important role in NPF. The contribution of regional transport to PM1 mass concentration was approximately 50% at both sites, same as that of the local emission. However, during the red-alert period when emission control took place, the contribution of regional transport was notably higher.Xiaojing SHEN Junying SUN Xiaoye ZHANG Yangmei ZHANG Yaqiang WANG Kaiyan TAN Peng WANG Lu ZHANG Xuefei QI Haochi CHE Zhouxiang ZHANG Junting ZHONG Huarong ZHAO Sanxue REN 2018Journal of Meteorological Research2018,32,1:2
17Compact CubeSat Gamma-ray detector for GRID mission显示文摘Gamma-Ray Integrated Detectors(GRID)mis-sion is a student project designed to use multiple gamma-ray detectors carried by nanosatellites(CubeSats),forming a full-time all-sky gamma-ray detection network that monitors the transient gamma-ray sky in the multi-mes-senger astronomy era.A compact CubeSat gamma-ray detector,including its hardware and firmware,was designed and implemented for the mission.The detector employs four Gd 2 Al 2 Ga 3 O 12:Ce(GAGG:Ce)scintillators coupled with four silicon photomultiplier(SiPM)arrays to achieve a high gamma-ray detection efficiency between 10 keV and 2 MeV with low power and small dimensions.The first detector designed by the undergraduate student team onboard a commercial CubeSat was launched into a Sun-synchronous orbit on October 29,2018.The detector was in a normal observation state and accumulated data for approximately one month after on-orbit functional and performance tests,which were conducted in 2019.Jia-Xing Wen Xu-Tao Zheng Jian-Dong Yu Yue-Peng Che Dong-Xin Yang Huai-Zhong Gao Yi-Fei Jin Xiang-Yun Long Yi-Hui Liu Da-Cheng Xu Yu-Chong Zhang Ming Zeng Yang Tian Hua Feng Zhi Zeng Ji-Rong Cang Qiong Wu Zong-Qing Zhao Bin-Bin Zhang Peng An GRID collaboration 2021Nuclear Science and Techniques2021,32,9:2
18Discovery of a wild,genetically pure Chinese giant salamander creates new conservation opportunities显示文摘Effective conservation of threatened biota relies on accurate assessments and scientific guidance.As an unfortunate example,Chinese giant salamanders(Andrias,CGS)remain critically endangered in nature.Misguided conservation efforts,e.g.,commercial propagation and releasing of millions of likely non-indigenous or interspecific hybrids,have further compromised conservation initiatives.Limited information on wild populations of CGS poses a significant conservation challenge.Following 18-month long field monitoring,we now report the discovery of a wild population of CGS in a closed nature reserve in Jiangxi Province,China.Genomic assessments reveal its genetic distinctiveness and do not detect genetic admixture with other species.Based on morphological and molecular evidences,we describe this CGS as a new species Andrias jiangxiensis sp.nov.This is the only known species of CGS today with a genetically pure,reproducing,in situ population.This discovery emphasizes the important role that closed nature reserves play in protecting species,and the necessity of integrating long-term field monitoring and genetic assessments.It sets a new pathway for discovering and conserving endangered species,especially for those biotas that are similarly being extirpated by anthropogenic translocations and overexploitation.Jing Chai Chen-Qi Lu Mu-Rong Yi Nian-Hua Dai Xiao-Dong Weng Ming-Xiao Di Yong Peng Yong Tang Qing-Hua Shan Kai Wang Huan-Zhang Liu Hai-Peng Zhao Jie-Qiong Jin Ru-Jun Cao Ping Lu Lai-Chun Luo Robert W.Murphy Ya-Ping Zhang Jing Che 2022Zoological Research2022,43,3:2
