| 1 | Orbit determination of Chang'E-3 and positioning of the lander and the rover显示文摘Chang’E-3 landed on the east of Sinus Iridum area on December 14,2013,performing China’s first successful soft landing on the lunar surface.We present the results on precision orbit determination and positioning of the lander and the rover.We describe the data,modeling,and methods used to achieve position knowledge over the period December 2–21,2014.In addition to the radiometric X-band range and Doppler tracking data,delta differential one-way ranging data are also used in the calculation,which show that they strongly improve the accuracy of the orbit reconstruction.Total position overlap differences are about 20 and 30 m for the 100 km 9 100 km and100 km9 15 km lunar orbit,respectively,increased by*50%with respect to CE-2 and at the same level as other lunar spacecrafts of recent era such as SELENE and lunar reconnaissance orbiter(LRO).The position error of the soft landing trajectory is less than 100 m.A kinematic statistical method is applied to determine the position of the lander and relative position of the rover with respect to the lander.The position difference of the lander is better than50 m compared to LRO photograph result.Compared with the delta very long baseline interferometry(VLBI)group delay between the lander and the rover,the delta VLBI phase delay can improve the relative position of the rover from*1,000 to*1 m. | Yong Huang Shengqi Chang Peijia Li Xiaogong Hu Guangli Wang Qinghui Liu Weimin Zheng Min Fan | 2014 | Chinese Science Bulletin2014，59，29： | 28 |
| 2 | Occurrence, polarity and bioavailability of dissolved organic matter in the Huangpu River,China显示文摘Dissolved organic matter(DOM)plays an important role in biogeochemical cycles in aquatic ecosystem.To investigate the characteristics of DOM in Huangpu River(the last tributary of the Yangtze River),surface water samples were collected along the river from December2011 to June,2013.The concentrations of dissolved organic carbon(DOC),the absorbance and fluorescence spectrum of DOM in water samples were measured.Fluorescent DOM in the Huangpu River was decomposed into four components by the parallel factor analysis(PARAFAC),including one humic-like substance and three protein-like substances.It showed that high spatial variability of DOC concentration was observed in the upstream water compared to the downstream water,and so did the absorbance coefficients of chromophoric dissolved organic matter and the total fluorescence intensities of different PARAFAC components of DOM.Furthermore,there was a large difference between the polarity and bioavailability of DOM in the Huangpu River.Polar compounds dominated tyrosine-like component of fluorescent DOM in all seasons.Tryptophan-like and humic-like substances had more polar fraction in summer and autumn than those in winter,while aromatic protein-like materials had the highest polar fraction in winter.Almost all of fluorescent DOM components were refractory in spring,while less than 20%of fluorescent DOM in average were biodegradable within 4 weeks in other seasons.We concluded that the spatial variation in the abundance of DOM in the Huangpu River is mainly affected by the water discharges from the Hangjiahu Plain and the seasonal difference in polarity and bioavailability of DOM is largely determined by its origins. | Qianqian Dong Penghui Li Qinghui Huang Ahmed A.Abdelhafez Ling Chen | 2014 | Journal of Environmental Sciences2014，26，9： | 7 |
| 3 | A Resource for Inactivation of MicroRNAs Using Short Tandem Target Mimic Technology in Model and Crop Plants显示文摘microRNAs (miRNAs)are endogenous small non-coding RNAs that bind to mRNAs and target them for cleavage and/or translational repression,leading to gene silencing.We previously developed short tandem target mimic (STTM)technology to deactivate endogenous miRNAs in Arabidopsis.Here,we created hundreds of STTMs that target both conserved and species-specific miRNAs in Arabidopsis,tomato,rice,and maize,providing a resource for the functional interrogation of miRNAs.We not only revealed the functions of several miRNAs in plant development,but also demonstrated that tissue-specific inactivation of a few miRNAs in rice leads to an increase in grain size without adversely affecting overall plant growth and development.RNA-seq and small RNAseq analyses of STTM156/157 and STTM165/166 transgenic plants revealed the roles of these miRNAs in plant hormone biosynthesis and activation,secondary metabolism,and ion-channel activity-associated electrophysiology,demonstrating that STTM technology is an effective approach for studying miRNA functions.To facilitate the study and application of STTM transgenic plants and to provide a useful platform for storing and sharing of information about miRNA-regulated gene networks,we have established an online Genome Browser (https://blossom.ffr.mtu.edu/designindex2.php) to display the transcriptomic and miRNAomic changes in STTMinduced miRNA knockdown plants. | Ting Peng Mengmeng Qiao Haiping Liu Sachin Teotia Zhanhui Zhang Yafan Zhao Bobo Wang Dongjie Zhao Lina Shi Cui Zhang Brandon Le Kestrel Rogers Chathura Gunasekara Haitang Duan Yiyou Gu Lei Tian Jinfu Nie Jian Qi Fanrong Meng Lan Huang Qinghui Chen Zhenlin Wang Jinshan Tang Xiaoqing Tang Ting Lan Xuemei Chen Hairong Wei Quanzhi Zhao Guiliang Tang | 2018 | Molecular Plant2018，11，11： | 7 |
| 4 | Distribution and origin of biologically available phosphorus in the water of the Meiliang Bay in summer显示文摘The investigation and continuous monitoring with an innovative iron oxide embedded cellulose acetate membrane (FeO/CAM) on the concentrations of biologically available phosphorus (BAP) were conducted in the Meiliang Bay of the Taihu Lake during summer in 2004. The results showed that the concentrations of dissolved (FeO-DP), particulate (FeO-PP) and total bioavailable phosphorus (FeO-P) had similar horizontal distribution. The BAP concentrations were the highest in those estuaries in the northern bay. With the decrease of the distance to the estuary or long shore,there was little difference between BAP concentrations in an open lake area. During the observation period, algal blooms occurred in most waters of the northern bay, which was reflected from the high concentrations of chlorophyll a (Chl-a). While they were not highest in the estuarine waters of those major rivers, this is the case for the BAP concentrations. The concentrations of Chl-a had a significantly positive correlation with those of bioavailable phosphorus in the open area of the Meiliang Bay.With the sediment resuspension induced by wind and wave, BAP concentrations increased in a short-term, indicating that the riverine P inputs mainly contribute to the concentrations of BAP in the estuarine water while internal P release was the major source of BAP in the open lake area. In the eutrophic shallow lake, the blooms of alga may cause pH increase and further result in internal P release. The above results showed that the new membrane of FeO/CAM can be used to monitor the concentrations of BAP and provide the scientific justifications for the control strategy of the lake eutrophication. | HUANG Qinghui, WANG Zijian, WANG Donghong, MA Mei & WANG Chunxia State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing 100085, China Key Laboratory of Yangtze Aquatic Environment (Ministry of Education), College of Environmental Science and Engineering, Tongji University, Shanghai 200092, China | 2006 | Science China Earth Sciences2006，49，z1： | 4 |
| 5 | Growth and photosynthesis responses of Phaeodactylum tricornutum to dissolved organic matter from salt marsh plant and sediment显示文摘The effects of allochthonous dissolved organic matter (DOM) on the growth and photosynthesis of Phaeodactylum tricornutum were investigated. P. tricornutum incubated in f/2 medium was exposed to DOM additives, which were extracted from the plant and sediment samples of a salt marsh in North Branch of the Yangtze estuary, China. During 12 days incubation, the chlorophyll fluorescence parameters of P. tricornutum were measured by a Phyto-PAM phytoplankton analyzer. Spectral properties of DOM in algae filtrates were also observed. The concentrations of chlorophyll a, active chlorophyll a, and the maximum quantum yield of photosystem II significantly decreased after four days of incubation, suggesting that the growth and photosynthetic efficiency of P. tricornutum were inhibited. After adding sediment-DOM extract, both a 250 /a 365 (the ratio of the absorption coefficients at 250 and 365 nm) and S values (spectral slope coefficients) of algae filtrates declined in the first two days, which demonstrated a loss of low molecular weight DOM. Parallel factor analysis of fluorescence spectra of DOM in algae filtrates revealed that DOM could be classified into two humic-like and two protein-like components. The fluorescence intensity of tyrosine-like component originating from algae increased significantly during incubation. This study supports the hypothesis that allochthonous DOM derived from salt marsh plant and sediment have a strong influence on the adjacent aquatic ecosystems. | Yihua Xiao Qinghui Huang Ling Chen Penghui Li | 2010 | Journal of Environmental Sciences2010，22，8： | 3 |

| 15 | Clinical significance of serum IgM and IgG levels in COVID-19 patients in Hubei Province,China显示文摘Background:There have been many studies about coronavirus disease 2019(COVID-19),but the clinical signifi-cance of quantitative serum severe acute respiratory syndrome-coronavirus-2(SARS-CoV-2)-specific IgM and IgG levels of COVID-19 patients have not been exhaustively analyzed.We aimed to investigate the time profiles of these IgM/IgG levels in COVID-19 patients and their correlations with clinical features.Methods:A multicenter clinical study was conducted from February 20 to March 52020.It involved 179 COVID-19 patients(108 males and 71 females)from five hospitals in Huangshi in Hubei Province,China.To detect SARS-CoV-2-specific IgM/IgG,quantitative antibody assays(two-step indirect immunoassays with direct chemilu-minescence technology)based on the nucleocapsid protein(NP)and spike protein 1(S1)were used.For normally distributed data,means were compared using the t-test,��2-test,or exact probability method.For categorical data,medians were compared using Mann-Whitney U test.Results:The median age was 57(44-69)years(58[38-69]for males and 57[49-68]for females).The median duration of positive nucleic acid test was 22.32(17.34-27.43)days.The mortality rate was relatively low(3/179,1.68%).Serum SARS-CoV-2-specific IgG was detected around week 1 after illness onset,gradually increased until peaking in weeks 4 and 5,and then declined.Serum IgM peaked in weeks 2 and 3,then gradually declined and returned to its normal range by week 7 in all patients.Notably,children had milder respiratory symptoms with lower SARS-CoV-2-specific IgM/IgG levels.The duration of positive nucleic acid test in the chronic obstructive pulmonary disease(COPD)group was 30.36(18.99-34.76)days,which was significantly longer than that in the non-COPD group(21.52[16.75-26.51]days;P=0.025).The peak serum SARS-CoV-2-specific IgG was sig-nificantly positively correlated with the duration of positive nucleic acid test.The incidence rate of severe and critical cases in the IgM hi group(using the median IgM level of 29.95 AU/mL as the cutofffor grouping)was about 38.0%(19/50),which was twice as much as that in the IgM lo group(18.4%;9/49).The patients with positive chest imaging and lymphocytopenia(<1×10^(9)/L)had a higher SARS-CoV-2-specific IgM level.Conclusions: Quantitative SARS-CoV-2-specific IgM and IgG levels are helpful for the diagnosis, severity classifi- cation, and management of COVID-19 patients, and they should be monitored in each stage of this disease. | Zhenjiang Bai Qing Li Qinghui Chen Changming Niu Yu Wei Hanpeng Huang Wei Zhao Nian Chen Xin Yao Qiang Zhang Chuanyong Mu Jian Feng Chuanlong Zhu Zhuo Li Ming Ding Binhui Feng Chaochao Jin Xiang Lu Yi Yang Shuiyan Wu Xiaochen Shu Haibo Qiu YingZi Huang | 2022 | Journal of Intensive Medicine2022，2，1： | 0 |

| 18 | Method for detecting soil total nitrogen contents based on pyrolysis and artificial olfaction显示文摘Soil nitrogen is an essential nutrient element for crop growth and development,and an important indicator of soil fertility characteristics.This study proposed a method based on pyrolysis and artificial olfaction to quickly and accurately determine the soil total nitrogen(STN)content.A muffle furnace was used to pyrolyze the soil samples,and ten different types of oxide semiconductor gas sensors were used to construct a sensor array to detect the soil samples’pyrolysis gas.The response curves of the sensors were tested at pyrolysis temperatures of 200℃,300℃,400℃,and 500℃ and at pyrolysis times of 1 min,3 min,5 min,and 10 min to obtain the optimal pyrolysis state of the soil samples.The optimal pyrolysis temperature was 400℃,and the pyrolysis time was 3 min.The response area,maximum value,average differential coefficient,variance value,maximum gradient value,average value,and 8th-second transient value of the sensor response curve were extracted to construct an artificial olfactory feature space of 121×10×7(121 soil samples,ten sensor numbers,seven extracted eigenvalues).Back-propagation neural network algorithm(BPNN),partial least squares regression algorithm(PLSR),and partial least squares regression combined with back-propagation neural network algorithm(PLSR-BPNN)were used to establish a prediction model of artificial olfactory feature space and STN content.Moreover,coefficient of determination(R2),root mean square error(RMSE),and the ratio of performance to deviation(RPD)were used as the performance indicators of the prediction results.The test results showed that the R2 of the PLSR,BPNN,and PLSR-BPNN models were 0.89033,0.81185,and 0.92186,and the RMSE values were 0.24297,0.37370,and 0.21781,and the RPD were 2.9964,1.9482,and 3.3426,respectively.The model established by the PLSR-BPNN algorithm has the highest R2 and RPD and the smallest RMSE,can achieve the accurate prediction of STN content,and therefore the model is rated as“excellent”.The detection method in this study achieves a low-cost,rapid,and accurate determination of STN content,and provides a new reference for the measurement of STN. | Mingwei Li Qinghui Zhu He Liu Xiaomeng Xia Dongyan Huang | 2022 | International Journal of Agricultural and Biological Engineering2022，15，3： | 0 |
