| 2 | Carbon carry capacity and carbon sequestration potential in China based on an integrated analysis of mature forest biomass显示文摘Forests play an important role in acting as a carbon sink of terrestrial ecosystem.Although global forests have huge carbon carrying capacity(CCC)and carbon sequestration potential(CSP),there were few quantification reports on Chinese forests.We collected and compiled a forest biomass dataset of China,a total of 5841 sites,based on forest inventory and literature search results.From the dataset we extracted 338 sites with forests aged over 80 years,a threshold for defining mature forest,to establish the mature forest biomass dataset.After analyzing the spatial pattern of the carbon density of Chinese mature forests and its controlling factors,we used carbon density of mature forests as the reference level,and conservatively estimated the CCC of the forests in China by interpolation methods of Regression Kriging,Inverse Distance Weighted and Partial Thin Plate Smoothing Spline.Combining with the sixth National Forest Resources Inventory,we also estimated the forest CSP.The results revealed positive relationships between carbon density of mature forests and temperature,precipitation and stand age,and the horizontal and elevational patterns of carbon density of mature forests can be well predicted by temperature and precipitation.The total CCC and CSP of the existing forests are 19.87 and 13.86 Pg C,respectively.Subtropical forests would have more CCC and CSP than other biomes.Consequently,relying on forests to uptake carbon by decreasing disturbance on forests would be an alternative approach for mitigating greenhouse gas concentration effects besides afforestation and reforestation. | LIU Ying Chun YU Gui Rui WANG Qiu Feng ZHANG Yang Jian XU Ze Hong | 2014 | Science China(Life Sciences)2014，57，12： | 15 |
| 3 | Identification of biomarkers for hepatocellular carcinoma by semiquantitative immunocytochemistry显示文摘AIM:To investigate the expression of key biomarkers in hepatoma cell lines,tumor cells from patients’blood samples,and tumor tissues.METHODS:We performed the biomarker tests in two steps.First,cells plated on coverslips were used to assess biomarkers,and fluorescence intensities were calculated using the NIH Image J software.The measured values were analyzed using the SPSS19.0 software to make comparisons among eight cell lines.Second,eighty-four individual samples were used to assess the biomarkers’expression.Negative enrichment of the blood samples was performed,and karyocytes were isolated and dropped onto pretreated glass slides for further analysis by immunofluorescence staining.Fluorescence intensities were compared among hepatocellular carcinoma(HCC)patients,chronic HBV-infected patients,and healthy controls following methods similar to those used for cell lines.The relationships between the expression of biomarkers and clinical pathological parameters were analyzed by Spearman rank correlation tests.In addition,we studied the distinct biomarkers’expression with three-dimensional laser confocal microscopy reconstructions,and Kaplan-Meier survival analysis was performed to understand the clinical significance of these biomarkers.RESULTS:Microscopic examination and fluorescence intensity calculations indicated that cytokeratin 8/18/19(CK)expression was significantly higher in six of the seven HCC cell lines examined than in the control cells,and the expression levels of asialoglycoprotein receptor(ASGPR)and glypican-3(GPC3)were higher in all seven HCC cell lines than in the control.Cells obtained from HCC patients’blood samples also displayed significantly higher expression levels of ASGPR,GPC3,and CK than cells from chronic HBV-infected patients or healthy controls;these proteins may be valuable surface biomarkers for identifying HCC circulating tumor cells isolated and enriched from the blood samples.The stem cell-like and epithelial-mesenchymal transition-related biomarkers could be detected on the karyocyte slides.ASGPR and GPC3 were expressed at high levels,and thus three-dimensional reconstructions were used to observe their expression in detail.This analysis indicated that GPC3 was localized in the cytoplasm and membrane,but that ASGPR had a polar localization.Survival analyses showed that expression of GPC3 and ASGPR is associated with a patient’s overall survival(OS).CONCLUSION:ASGPR,GPC3,and CK may be valuable HCC biomarkers for CTC detection;the expression of ASGPR and GPC3 might be helpful for understanding patients’OS. | Hong Mu Kai-Xuan Lin Hong Zhao Shu Xing Cong Li Fang Liu Hai-Zhen Lu Ze Zhang Yu-Lin Sun Xi-Yun Yan Jian-Qiang Cai Xiao-Hang Zhao | 2014 | World Journal of Gastroenterology2014，20，19： | 8 |

| 6 | Back-n white neutron source at CSNS and its applications显示文摘Back-streaming neutrons from the spallation target of the China Spallation Neutron Source(CSNS)that emit through the incoming proton channel were exploited to build a white neutron beam facility(the so-called Back-n white neutron source),which was completed in March 2018.The Back-n neutron beam is very intense,at approximately 29107 n/cm2/s at 55 m from the target,and has a nominal proton beam with a power of 100 kW in the CSNS-I phase and a kinetic energy of 1.6 GeV and a thick tungsten target in multiple slices with modest moderation from the cooling water through the slices.In addition,the excellent energy spectrum spanning from 0.5 eV to 200 MeV,and a good time resolution related tothe time-of-flight measurements make it a typical white neutron source for nuclear data measurements;its overall performance is among that of the best white neutron sources in the world.Equipped with advanced spectrometers,detectors,and application utilities,the Back-n facility can serve wide applications,with a focus on neutron-induced cross-sectional measurements.This article presents an overview of the neutron beam characteristics,the experimental setups,and the ongoing applications at Backn. | Jing-Yu Tang Qi An Jiang-Bo Bai Jie Bao Yu Bao Ping Cao Hao-Lei Chen Qi-Ping Chen Yong-Hao Chen Zhen Chen Zeng-Qi Cui Rui-Rui Fan Chang-Qing Feng Ke-Qing Gao Xiao-Long Gao Min-Hao Gu Chang-Cai Han Zi-Jie Han Guo-Zhu He Yong-Cheng He Yang Hong Yi-Wei Hu Han-Xiong Huang Xi-Ru Huang Hao-Yu Jiang Wei Jiang Zhi-Jie Jiang Han-Tao Jing Ling Kang Bo Li Chao Li Jia-Wen Li Qiang Li Xiao Li Yang Li Jie Liu Rong Liu Shu-Bin Liu Xing-Yan Liu Ze Long Guang-Yuan Luan Chang-Jun Ning Meng-Chen Niu Bin-Bin Qi Jie Ren Zhi-Zhou Ren Xi-Chao Ruan Zhao-Hui Song Kang Sun Zhi-Jia Sun Zhi-Xin Tan Xin-Yi Tang Bin-Bin Tian Li-Jiao Wang Peng-Cheng Wang Zhao-Hui Wang Zhong-Wei Wen Xiao-Guang Wu Xuan Wu Li-Kun Xie Xiao-Yun Yang Yi-Wei Yang Han Yi Li Yu Tao Yu Yong-Ji Yu Guo-Hui Zhang Lin-Hao Zhang Qi-Wei Zhang Xian-Peng Zhang Yu-Liang Zhang Zhi-Yong Zhang Lu-Ping Zhou Zhi-Hao Zhou Ke-Jun Zhu 无 | 2021 | Nuclear Science and Techniques2021，32，1： | 4 |
| 7 | Singularity Robust Path Planning for Real Time Base Attitude Adjustment of Free-floating Space Robot显示文摘This paper presents a singularity robust path planning for space manipulator to achieve base(satellite) attitude adjustment and end-effector task. The base attitude adjustment by the movement of manipulator will save propellant compared with conventional attitude control system. A task-priority reaction null-space control method is applied to achieve the primary task of adjusting attitude and secondary task of accomplishing end-effector task. Furthermore, the algorithm singularity is eliminated in the proposed algorithm compared with conventional reaction null-space algorithm. And the singular value filtering decomposition is introduced to dispose the dynamic singularity, the unit quaternion is also introduced to overcome representation singularity. Hence, a singularity robust path planning algorithm of space robot for base attitude adjustment is derived. A real time simulation system of the space robot under Linux/RTAI(realtime application interface) is developed to verify and test the feasibility and reliability of the method. The experimental results demonstrate the feasibility of online base attitude adjustment of space robot by the proposed algorithm. | Cheng Zhou Ming-He Jin Ye-Chao Liu Ze Zhang Yu Liu Hong Liu | 2017 | International Journal of Automation and computing2017，14，2： | 3 |
| 8 | Oxygen Atom Exchange Mechanism in Reaction of OH Radical with AsO显示文摘Oxygen atom exchange reaction mechanism in the reaction of OH radicals with AsO was investigated by means of the density functional theory (DFT) with 6 311++G( 3df,3pd ) and 6 311++G( d,p ) basis sets. The calculated results suggest that the reaction between OH and AsO should make the oxygen atoms exchange rapidly because the barrier to isomerization is significantly less than the HO-AsO bond dissociation energy. | CHI Yu-juan 1, YU Hai tao 1,2** , FU Hong gang 1,2 HUANG Xu ri 2, LI Ze sheng 2 and SUN Chia chung 21.

| 10 | Verticillium dahliae Secretory Effector PevD1 Induces Leaf Senescence by Promoting ORE1-Mediated Ethylene Biosynthesis显示文摘Leaf senescence,the final stage of leaf development,is influenced by numerous internal and environmental signals.So far,how biotic stresses such as pathogen infection regulate leaf senescence is unclear.Here,we found that the premature leaf senescence caused by a soil-borne vascular fungus Verticillium dahliae in Arabidopsis was impaired by the mutation of a protein elicitor from V.dahliae 1(PevD1).Constitutive or inducible overexpression of PevD1 accelerated Arabidopsis leaf senescence.A senescence-associated NAC transcription factor,ORE1,was targeted by PevD1.PevD1 interacted with and stabilized ORE1 protein by disrupting its interaction with the RING-type ubiquitin E3 ligase NLA.Mutation of ORE1 suppressed the premature senescence caused by overexpressing PevD1.Overexpression of ORE1 or PevD1 led to enhanced ethylene production,and ORE1 mediated PevD1-induced ethylene biosynthesis by directly binding to the ACS6 promoter.Loss-of-function of ACSs suppressed V.dahliae-induced leaf senescence in ORE1-overexpressing plants.Interestingly,PevD1 also interacted with Gossypium hirsutum ORE1(GhORE1),and virus-induced gene silencing of GhORE1 delayed V.dahliae-triggered leaf senescence in cotton,indicative of the existence of a conserved mechanism in plants.Altogether,our study demonstrates that V.dahliae induces leaf senescence by secreting the effector PevD1 to regulate the ORE1-ACS6 cascade,providing new insight into biotic stress-induced senescence in plants. | Yi Zhang Yuhan Gao Hou-Ling Wang Chengcheng Kan Ze Li Xiufen Yang Weilun Yin Xinli Xia Hong Gil Nam Zhonghai Li Hongwei Guo | 2021 | Molecular Plant2021，14，11： | 2 |

| 13 | Discrete twinning dynamics and size-dependent dislocation-to twin transition in body-centred cubic tungsten显示文摘Body-centred cubic(BCC) metals are known to have unstable intrinsic stacking faults and high resistance to deformation twinning, which can strongly influence their twinning behaviour. Though twinning mechanisms of BCC metals have been investigated for more than 60 years, the atomistic level dynamics of twinning remains under debate, especially regarding its impact on competition between twinning and slip. Here, we investigate the atomistic level dynamics of twinning in BCC tungsten(W) nanowires using in situ nanomechanical testing. Quantitative experimental studies directly visualize that deformation twins in W nanowires have a minimum size of six-layers and grow in increments of approximately three-layers at a time, in contrast to the layer-by-layer growth of deformation twins in face-centred cubic metals. These unique twinning dynamics induces a strong competition with ordinary dislocation slip,as exhibited by a size-dependent dislocation-to-twin transition in W nanowires, with a transition size of ~40 nm. Our work provides physical insight into the dynamics of twinning at the atomic level, as well as a size-dependent dislocation-twinning competition, which have important implications for the plastic deformation in a broad class of BCC metals and alloys. | Jiangwei Wang Anik H.M.Faisal Xiyao Li Youran Hong Qi Zhu Hongbin Bei Ze Zhang Scott X Mao Christopher R.Weinberger | 2022 | Journal of Materials Science & Technology2022，，11： | 2 |
| 14 | Molecular detection of Anaplasma infections in ixodid ticks from the Qinghai-Tibet Plateau显示文摘Anaplasma species are tick-transmitted obligate intracellular bacteria that infect many wild and domestic animals and humans.The prevalence ofAnaplasma spp.in ixodid ticks of Qinghai Province is poorly understood.In this study,a total of 1104 questing adult ticks were investigated for the infection ofAnaplasma species.As a result,we demonstrated the total infection rates of 3.1,11.1,5.6,and 4.5%forA.phagocytophilum,A.bovis,A.ovis andA.capra,respectively.All of the tick samples were negative forA.marginale.The positive rates ofA.phagocytophilum,A.ovis andA.capra in different tick species were significantly different.The positive rates ofA.capra andA.bovis in the male ticks were significantly higher than that in the female ticks.Sequence analysis ofA.ovis showed 99.5-100%identity to the previous reported isolates.The sequences ofA.phagocytophilum had 100%identity to strains Ap-SHX21,JC3-3 and ZAM dog-181 from sheep,Mongolian gazelles,and dogs.Two genotypes ofA.capra were found based on 16S rRNA,citrate synthase(gltA)gene and heat shock protein(groEL)gene analysis.In conclusion,A.bovis,A.ovis,A.phagocytophilum,andA.capra were present in the ticks in Qinghai Province.Anaplasma infection is associated with tick species,gender and distribution.These data will be helpful for understanding prevalence status ofAnaplasma infections in ticks in Qinghai-Tibet Plateau. | Rong Han Ji-Fei Yang Muhammad Uzair Mukhtar Ze Chen Qing-Li Niu Yuan-Qing Lin Guang-Yuan Liu Jian-Xun Luo Hong Yin Zhi-Jie Liu | 2019 | Infectious Diseases of Poverty2019，8，1： | 2 |
| 15 | Occurrence and characteristics of sporadic K layer observed by lidar over Beijing, China显示文摘A double-laser-beam lidar was successfully developed in 2010 to measure the K layer over Yanqing County, Beijing(40.5°N, 116.2°E). Comprehensive statistical analyses of sporadic K(Ks) layer parameters were conducted using two years of lidar data, and the parameters of the Ks layers and their distribution obtained by the analyses are described. The seasonal distribution of Ks occurrence was obtained, with two maxima observed in January and July, respectively. The seasonal distributions of sporadic E(Es) occurrence over Beijing differ from those of Ks occurrence. However, good correlations between Es and Ks in case by case study were found. We also found that four Ks events with peak altitudes lower than 90 km were associated with large and sharp temperature increases in five comparative examples. | JIAO Jing YANG Guo Tao WANG Ji Hong WANG Ze Long YANG Yong | 2016 | Science China Earth Sciences2016，59，3： | 2 |

| 18 | Determination of long-term strength of frozen loess after numerous freeze-thaw cycles显示文摘In order to determine the changing rule of long-term frozen soil strength and elucidate the connection between long-term strength and soil physical properties,frozen loess was subjected to 4,6,8,10,and 50 freeze-thaw cycles,under closed-state conditions in a constant-temperature box.The frozen samples were tested on a spherical template indenter,and the results show that under the effect of repeated freeze-thaw cycles,the long-term strength of frozen loess decreased; changes in the mechanical property indices were highly unstable during the first 10 cycles; the soil strength and density were the greatest at the eighth cycle while the void ratio was the smallest; and after eight cycles all of the indices had less fluctuation and certain rising or falling tendencies.By converting the number of freeze-thaw cycles into elapsed time in the tests,three different forecasting methods of long-term soil strength could be assessed and the soil equivalent cohesive force after 10 years,20 years,or 30 years could be estimated. | Hong Zhou Ze Zhang WenJie Feng Jiao Ming ZhongQiong Zhang | 2014 | Research in Cold and Arid Regions2014，6，5： | 2 |
| 19 | An Investigation on the Molecular Characteristics and Intracellular Growth Ability among Environmental and Clinical Isolates of Legionella pneumophila in Sichuan Province, China显示文摘Objective To investigate the molecular characteristics and intracellular growth ability of Legionella pneumophila(L. pneumophila) strains from 1989 to 2016 in Sichuan Province, China. Methods Seventy-nine isolates of L. pneumophila were collected from environmental and clinical sources, including cooling towers, hot springs, bath water, fountains, and patients, and identified with 16 S rRNA gene analysis and serum agglutination assay. The isolates were then typed by Sequence-Based Typing(SBT), and Genotyping of forty-two LP1 strains were analyzed by means of multiple-locus VNTR analysis with 8 loci(MLVA-8). All strains were further analyzed for two virulence genes: Legionella vir homologue(lvh) and repeats in structural toxin(rtx A). The intracellular growth ability of 33 selected isolates was determined by examining their interaction with J774 cells. Results All isolates were identified to L. pneumophila including 11 serogroups, among which the main serogroup were LP1, accounting for 54.43%. Thirty-three different sequence types(STs) from five main clonal groups and five singletons were identified, along with 8 different MLVA patterns. Both the lvh and rtx A loci were found in all 79 strains. Thirty isolates showed high intracellular growth ability in J774 cells. Conclusion L. pneumophila is a potential threat to public health, and effective control and prevention strategies are urgently needed. | ZENG Lin Zi LIAO Hong Yu LUO Long Ze HE Shu Sen QIN Tian ZHOU Hai Jian LI Hong Xia CHEN Da Li CHEN Jian Ping | 2019 | Biomedical and Environmental Sciences2019，32，7： | 1 |
