| 1 | Development of a national VNIR soil-spectral library for soil classification and prediction of organic matter concentrations显示文摘Soil visible-near infrared diffuse reflectance spectroscopy(vis-NIR DRS)has become an important area of research in the fields of remote and proximal soil sensing.The technique is considered to be particularly useful for acquiring data for soil digital mapping,precision agriculture and soil survey.In this study,1581 soil samples were collected from 14 provinces in China,including Tibet,Xinjiang,Heilongjiang,and Hainan.The samples represent 16 soil groups of the Genetic Soil Classification of China.After air-drying and sieving,the diffuse reflectance spectra of the samples were measured under laboratory conditions in the range between 350 and 2500 nm using a portable vis-NIR spectrometer.All the soil spectra were smoothed using the Savitzky-Golay method with first derivatives before performing multivariate data analyses.The spectra were compressed using principal components analysis and the fuzzy k-means method was used to calculate the optimal soil spectral classification.The scores of the principal component analyses were classified into five clusters that describe the mineral and organic composition of the soils.The results on the classification of the spectra are comparable to the results of other similar research.Spectroscopic predictions of soil organic matter concentrations used a combination of the soil spectral classification with multivariate calibration using partial least squares regression(PLSR).This combination significantly improved the predictions of soil organic matter(R2=0.899;RPD=3.158)compared with using PLSR alone(R2=0.697;RPD=1.817). | SHI Zhou WANG QianLong PENG Jie JI WenJun LIU HuanJun LI Xi Raphael A VISCARRA ROSSEL | 2014 | Science China Earth Sciences2014，57，7： | 32 |
| 2 | Os isotopic compositions of a cobalt-rich ferromanganese crust profile in Central Pacific显示文摘187Os/188Os ratios in all sub-layers of the Co-rich ferromanganese crust MP5D17 from Line Seamount in Central Pacific have been systematically determined. The 187Os/188Os values in this crust are highly variable, ranging from 0.4262 to 1.0155. From the bottom to the top, the os-mium isotopic ratios of the crust display a regular variation trend, which correlates well with its changes in structure and texture in the vertical profile. In comparison with the evolu-tion curve of Os isotopic composition in seawater over the past 80 Ma, a similar evolution tendency can be found with respect to the Os isotopic composition of the crust in this study. It is preliminarily concluded that the crust MP5D17 began to grow at about 72 Ma, and underwent three growth hiatuses, corresponding to the geological ages of 64, 53 and 37 Ma, respectively. | FU Yazhou PENG Jiantang QU Wenjun HU Ruizhong SHI Xuefa DU Andao | 2005 | Chinese Science Bulletin2005，50，18： | 13 |
| 3 | Re-Os dating of auriferous pyrite from the Zhenyuan super-large gold deposit in Ailaoshan gold belt,Yunnan Province,Southwestern China显示文摘Zhenyuan gold deposit is the largest super large gold deposit in the Ailaoshan gold belt,but its precise mineralization age is still lack.Re-Os isotopic age of the auriferous pyrite from the Zhenyuan gold deposit was determined by using a high-resolution inductively coupled plasma mass spectrometry(HR-ICP-MS).The pyrite samples were decomposed in carius tubes,Os was separated by distillation and Re was extracted by acetone,respectively.The results show that the Re-Os isochron age is 229±38 Ma(MSWD=2.0,confidence level is 95%),with an initial 187 Os/188 Os value of 0.68±0.24 and a corresponding Os value of 442±91.The Re/Os ratios of the pyrite vary from 40.8 to 100.5.The data suggest that at least one important ore-forming event was occurred during Indosinian epoch,and the ore-forming materials probably derived from mixed sources of crustal and mantle,while the later dominated.The Ailaoshan composite orogen experienced complicated evolutional processes,including formation of Precambrian-Early Paleozoic basement,subduction and orogenesis of Late Paleozoic era,collisional orogenesis of Late Hercynian-Indosinain epoch,and extensional or striking orogenesis of Yanshainan-Cenozoic epoch.The polycycle tectonic evolution and magmatism in this area caused multi-stage and superposition metallization characteristics of the Zhenyuan gold deposit:the mineralization probably occur mainly during the Indosinian collisional orogeny,while the minor gold ores of altered granite-porphyry and altered lamprophyre may be formed in the late superposition metallization. | SHI GuiYong SUN XiaoMing PAN WeiJian HU BeiMing QU WenJun DU AnDao LI Chao | 2012 | Chinese Science Bulletin2012，57，35： | 9 |
| 4 | Allele-defined genome reveals biallelic differentiation during cassava evolution显示文摘Dear Editor,Generation of heterozygous genomes by hybridization between or within species can help maintain plant diversity and serve as a potential source of new species(Baek et al.,2018).Moreover,genomic heterozygosity is associated with genomic coadaptation,developmental stability,and heterosis.Accurate definition of alleles in haplotypes is necessary to precisely characterize allelic variation controlling agriculturally important traits(Shi et al.,2019).Currently,most released genomes have mosaic assembly of haplotypes due to random selection or collapse of alleles during genome assembly(Shi et al.,2019),which masked allelic variation and functional differentiation of divergent alleles in heterozygous species. | Wei Hu Changmian Ji Haitao shi Zhe Liang Zehong Ding Jianqiu Ye Wenjun Ou Gang Zhou Weiwei Tie Yan Yan Jinghao Yang Xiaoying Yang Yunxie Wei Zhiqiang Jin Jianghui Xie Ming Peng Wenquan Wang Anping Guo Biyu Xu Jianchun Guo Songbi Chen Liming Ma Mingcheng Wang Yang Zhou Xiaolong Li Ruoxi Li Siyi Guo Xinhui Xiao Zhongqing Wan Feifei An Jie Zhang Qingyun Leng Yin Li Ray Ming Kaimian Li | 2021 | Molecular Plant2021，14，6： | 8 |
| 5 | Classification of Ferrallitic Soils in Chinese Soil Taxonomy显示文摘The development of the classification of ferrallitic soils in China is reviewed and the classification ofFerralisols and Ferrisols in Chinese Soil Taxonomy is introduced in order to discuss the correlation betweenthe ferrallitic soil classification in the Chinese Soil Taxonomy and those of the other soil classification systems.In the former soil classification systems of China, the ferrallitic soils were classified into the soil groups ofLatosols, Latosolic red soils, Red soils, Yellow soils and Dry red soils, according to the combination of soilforming conditions, soil-forming processes, soil features and soil properties. In the Chinese Soil Taxonomy,most of ferrallitic soils are classified into the soil orders of Ferralisols and Ferrisols based on the diagnostichorizons and/or diagnostic characteristics with quantitatively defined properties. Ferralisols are the soilsthat have ferralic horizon, and they are merely subdivided into one suborder and two soil groups. Ferrisolsare the soils that have LAC-ferric horizon but do not have ferralic horizon, and they are subdivided intothree suborders and eleven soil groups. Ferralisols may correspond to part of Latosols and Latosolic red soils.Ferrisols may either correspond to part of Red soils, Yellow soils and Dry red soils, or correspond to part ofLatosols and Latosolic red soils. | GONG ZITONG CHEN ZHICHENG ZHAO WENJUN and SHI HUA(Institute of Soil Science, the Chinese Academy of Sciences, P.O.

| 7 | Nano-selenium controlled cadmium accumulation and improved photosynthesis in indica rice cultivated in lead and cadmium combined paddy soils显示文摘Selenium nanoparticles(Se NPs) are less toxic and more biocompatible than selenite or selenate. However, studies involving spraying with Se NPs for reducing accumulation of cadmium(Cd) and lead(Pb) in rice grains have been rarely reported as yet. Herein, indica rice seedlings cultivated in Cd + Pb-spiked paddy soils(denoted as positive control) were sprayed with Se NPs sols for four times from tillering to booting stage. Compared to positive control, 50–100 μmol/L Se NPs downregulated Cd transporters-related genes such as Os LCT 1, OsH MA 2 and Os CCX2 in leaves and OsLCT1, Os PCR1 and Os CCX2 genes in node I at filling stage. Meanwhile, Se-binding protein 1 was distinctly elevated, involving the repression of Cd and Pb transportation to rice grains. Se NPs also differentially improved RuBP carboxylase and chlorophylls especially some key genes and proteins involving photosynthetic system. Besides, 25–50 μmol/L Se NPs diminished reactive oxygen species overproduction from NADPH oxidases whereas boosted glutathione peroxidase, reducing protein carbonylation in rice seedlings. However, the antioxidant isozymes and oxidatively modified proteins were slightly rebounded at 100 μmol/L. Se contents were noticeably elevated and confirmed to exist as selenomethionine in the rice grains following all the treatments by Se NPs. Thus, the optimal dosage of Se NPs for foliar application is 50 μmol/L, which significantly decreased Cd accumulation, improved photosynthesis and Se enrichment whereas caused no distinct reduction of Pb in the grains. Thus, an appropriate dosage of Se NPs can be conducted to decrease Cd accumulation, improve photosynthesis, and organic Se contents in rice grains. | Chengrun Wang Tingting Cheng Haitao Liu Fangyun Zhou JifengZhang Min Zhang Xinya Liu Wenjun Shi Tong Cao | 2021 | Journal of Environmental Sciences2021，33，5： | 5 |

| 9 | Microstructure and cutting performance of Ti(C, N)-based cermets heat-treated in nitrogen显示文摘Ti(C, N)-based cermets were treated using hot isostatic pressing (HIP) at 1423 K in nitrogen. The microstructures compared with the as-sintered cermets were investigated using X-ray diffraction, scanning electron microscopy, transmis- sion electron microscopy, energy-dispersive X-ray analysis, and electron microprobe analysis. It was found that high nitro- gen activity in the surface zone resulted in the formation of gradient structure. Approximately 20-μm-deep, nitrogen-rich and titanium-rich hard surface zone was introduced by the heat treatment. The nitrogen activity was the driving force that caused the transportation of the atoms through the binder, titanium towards the surface, and tungsten and molybdenum in- wards. In the surface zone, the particle size became fine, the inner rim disappeared, and the volume fraction of the outer rim and the binder phase considerably reduced. Small grains of TiN, WC, Mo2C, and nitrogen-rich carbonitride phases formed in the surface zone during the heat treatment, improving the tribological property of the heat-treated cermet. | LIU Wenjun XIONG Weihao ZHENG Yong SHI Zengmin YE Jiajian | 2007 | Rare Metals2007，26，4： | 4 |
| 10 | Post-marketing safety surveillance and reevaluation of Motherwort injection:A clinical study of 10094 cases显示文摘OBJECTIVE:To investigate the safety profiles of Motherwort injection(MI).METHODS:A multi-center,prospective and drugderived hospital intensive monitoring method was conducted to assess the safety of MI in real world applications.This study was based on a very large population after the injection was approved and marketed in China.All patients using the injection in participating hospitals were monitored to determine the incidence,pattern,severity and outcome of associated adverse events.RESULTS:The post-marketing surveillance was performed in 10 094 female patients from April to December,2015.The incidence of adverse drug reactions(ADRs) was 0.79‰(8/10 094).Among the 8 patients,the reported adverse events mainly included systemic abnormalities,such as fever,chills and eyelid edema;skin and appendages disorders,such as pruritus and rash;gastrointestinal disorders,such as nausea,abdominal distension and pain;heart rate and rhythm disorders,such as palpitation and increased heart rate.All of these ADRs were mild in severity.CONCLUSION:In this study the ADRs incidence rate of MI is very low,which supports that it is generally safe for use in obstetric and gynecological diseases.However,the total number of 8 ADRs recorded over a relatively short time span seems limited,and the low number of reports could not represent an absolute guarantee of safety. | Cao Shan Zhang Wenhao Zhao Ziwei Heng Mingli Bu Huaien Wang Hongwu Liu Xinghui Wang Zhong Cai Yan Ma Yuyan Cui Shihong Deng Jihong Ding Guifeng Ding Yajuan Dong Linhong Duan Zhentao Fan Ling Fan Yang Fu Fen He Jing Ji Shuying Jin Lin Li Hong Li Hongying Liao Tao Lu Wei Luo Xiucui Lü Zhihui Ma Fengchun Ma Dafeng Shi Tianyun Sun Juying Sun Xiaotong Teng Hong Wang Jinhua Wang Ruihua Wang Ying Wang Zhengling Xi Jie Xu Minjuan Xu Zhihong Yan Qian Yang Cuirong Yang Yimei Yin Jie Yu Jinhua Yuan Wenjun Zhang Guanli Zhang Meihua Zhao Renfeng Zhong Yonghong Zhou Jian | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 4 |
| 11 | Materials Experiment on Tiangong-2 Space Laboratory显示文摘During the China's Tiangong-2(TG-2) flight mission, the experiments of 18 kinds of material samples were conducted in space by using a Multiple Materials Processing Furnace(MMPF) mounted in the orbital module of the TG-2 space laboratory. After the experiments of 12 kinds of samples of the first and second batches were completed successfully, astronauts packed and brought them back to the ground by ShenzhouII spacecraft. By studying processing and formation on semiconductor and optoelectronics materials, metal alloys and metastable materials, functional single-crystal, micro-and nano-composite materials encapsulated in sample ampoules both in space and on Earth, we expect to explore some physical and chemical processes and mechanism of the materials formation that are normally obscured and therefore are difficult to study quantitatively on the ground due to the gravity-induced convection, to obtain the processing and synthesis technology for preparing high quality materials, and lead to the improvement and development of materials processing techniques on Earth, and also develop the experiment device and comprehensive ability for materials experiment in microgravity environment. This report briefly introduces the main points of each research work and preliminary comparative analysis results of 12 samples carried out by scientists undertaking research task. | LI Xiangyang LU Ye MENG Xiangjian WANG Jianlu WANG Reng CHEN Lidong HUA Zile LI Xiaoya SHI Jianlin LIU Jinfeng XU Guisheng WEI Bingbo XIE Wenjun YIN Zhigang ZHANG Xingwang JIANG Hongxiang LI Hong LUO Xinghong ZHANG Haifeng ZHAO Jiuzhou WANG Binbin PAN Mingxiang | 2018 | 空间科学学报2018，38，5： | 4 |
| 12 | Design and Implementation of a TDD-Based 128-Antenna Massive MIMO Prototype System显示文摘Owing to the dramatic mobile IP growth,the emerging Internet of Things,and cloud-based applications,wireless networking is witnessing a paradigm shift.By fully exploiting spatial degrees of freedom,massive multiple-input-multiple-output(MIMO) systems promise significant gains in data rates and link reliability.Although the research community has recognized the theoretical benefits of these systems,building the hardware of such complex systems is a challenge in practice.This paper presents a time division duplex(TDD)-based 128-antenna massive MIMO prototype system from theory to reality.First,an analytical signal model is provided to facilitate the setup of a feasible massive MIMO prototype system.Second,a link-level simulation consistent with practical TDDbased massive MIMO systems is conducted to guide and validate the massive MIMO system design.We design and implement the TDDbased 128-antenna massive MIMO prototype system with the guidelines obtained from the link-level simulation.Uplink real-time video transmission and downlink data transmission under the configuration of multiple single-antenna users are achieved.Comparisons withstate-of-the-art prototypes demonstrate the advantages of the proposed system in terms of antenna number,bandwidth,latency,and throughput.The proposed system is also equipped with scalability,which makes the system applicable to a wide range of massive scenarios. | Xi Yang Wenjun Lu Ning Wang Karl Nieman Chao-Kai Wen Chuan Zhang Shi Jin Xiaomin Mu Ian Wong Yongming Huang Xiaohu You | 2017 | China Communications2017，14，12： | 3 |
| 13 | Influenza A virus use of BinCARD1 to facilitate the binding of viral NP to importinα7 is counteracted by TBK1-p62 axis-mediated autophagy显示文摘As a major component of the viral ribonucleoprotein(vRNP)complex in influenza A virus(IAV),nucleoprotein(NP)interacts with isoforms of importinαfamily members,leading to the import of itself and vRNP complex into the nucleus,a process pivotal in the replication cycle of IAV.In this study,we found that BinCARD1,an isoform of Bcl10-interacting protein with CARD(BinCARD),was leveraged by IAV for efficient viral replication.BinCARD1 promoted the nuclear import of the vRNP complex and newly synthesized NP and thus enhanced vRNP complex activity.Moreover,we found that BinCARD1 interacted with NP to promote NP binding to importinα7,an adaptor in the host nuclear import pathway.However,we also found that BinCARD1 promoted RIG-I-mediated innate immune signaling by mediating Lys63-linked polyubiquitination of TRAF3,and that TBK1 appeared to degrade BinCARD1.We showed that BinCARD1 was polyubiquitinated at residue K103 through a Lys63 linkage,which was recognized by the TBK1-p62 axis for autophagic degradation.Overall,our data demonstrate that IAV leverages BinCARD1 as an important host factor that promotes viral replication,and two mechanisms in the host defense system are triggered—innate immune signaling and autophagic degradation—to mitigate the promoting effect of BinCARD1 on the life cycle of IAV. | Xuyuan Wang Li Jiang Guangwen Wang Wenjun Shi Yuzhen Hu Bo Wang Xianying Zeng Guobin Tian Guohua Deng Jianzhong Shi Liling Liu Chengjun Li Hualan Chen | 2022 | Cellular & Molecular Immunology2022，19，10： | 3 |

| 15 | A-π-D-π-A small-molecule donors with different end alkyl chains obtain different morphologies in organic solar cells显示文摘For bulk-heterojunction organic solar cells, the morphology of the blend films highly influence the exciton dissociation and charge transport process. In this work, two novel A-π-D-π-A(A represents the acceptor unit and D represents the donor unit) backbone structure small molecular electron donors based on two dimensional conjugated naphtho[1,2-b:5,6-b']dithiophene(NDT) with different end alkyl chains, named as NDT-3T-EH and NDT-3T-O, have been designed and synthesized. The photovoltaic property of NDT-3T-O-based device is better than that of the NDT-3T-EH and the best efficiency reaches 7.06%, and the photovoltaic property of NDT-3T-EH reaches 6.11%. The difference in the performance should be attributed to the different morphology and phase separation resulted from the different crystallinity and aggregation ability of two donors. The results demonstrate that the optimized end alkyl chains can be used to design A-π-D-π-A backbone structure small molecular electron donors for smallmolecule organic solar cells. | Yanan Shi Chen Yang Huan Li Lixuan Liu Ruimin Zhou Wenjun Zou Zhen Wang Qiong Wu Dan Deng Jianqi Zhang Kun Lu Zhixiang Wei | 2019 | Chinese Chemical Letters2019，30，4： | 3 |
| 16 | Osmium isotope of the Co-rich crust from seamount Allison, central Pacific and its use for determination of growth hiatus and growth age显示文摘Based on its microstructure, Co-rich crust A1-1 from seamount Allison, central Pacific, was scraped at averaged interval of 1.3 mm to measure osmium isotopic composition, and subsequently to establish the 187Os/188Os profile of scraping section of the crust. By observing the variation of 187Os/188Os under 10Be chronology and matching it to the well-known seawater Os isotope evolution of the past 40 Ma, two growth hiatuses (H1 and H2) occurring in the periods respectively between 13.6 and 29.6 Ma and between 8 and 9.8 Ma in the crust were recognized. According to the two hiatuses, the dating scheme for each scraped layer of the crust was suggested. For the upper layers younger than 6.8Ma, their growth ages were calibrated under 10Be chronology; for the lower layers older than 6.8Ma, their growth ages were obtained from 187Os/188Os evaluation curve by linear interpolation. Hereby, the age for the most inner layer of the crust was determined to be 39.5 Ma. H1 and H2 exactly correspond to the boundary between phosphatization and non-phosphatization and volcanic ash layer in the crust, respectively. | MENG XianWei LIU YanGuang QU WenJun SHI XueFa | 2008 | Science China Earth Sciences2008，51，10： | 2 |

| 18 | Endothelial METRNL determines circulating METRNL level and maintains endothelial function against atherosclerosis显示文摘METRNL is a recently identified secreted protein with emerging functions.This study is to find major cellular source of circulating METRNL and to determine METRNL novel function.Here,we show METRNL is abundant in human and mouse vascular endothelium and released by endothelial cells using endoplasmic reticulum-Golgi apparatus pathway.By creating endothelial cell-specific Metrnl knockout mice,combined with bone marrow transplantation to produce bone marrow-specific deletion of Metrnl,we demonstrate that most of circulating METRNL(approximately 75%)originates from the endothelial cells.Both endothelial and circulating METRNL decrease in atherosclerosis mice and patients.By generating endothelial cell-specific Metrnl knockout in apolipoprotein E-deficient mice,combined with bone marrow-specific deletion of Metrnl in apolipoprotein E-deficient mice,we further demonstrate that endothelial METRNL deficiency accelerates atherosclerosis.Mechanically,endothelial METRNL deficiency causes vascular endothelial dysfunction including vasodilation impairment via reducing eNOS phosphorylation at Ser1177 and inflammation activation via enhancing NFκB pathway,which promotes the susceptibility of atherosclerosis.Exogenous METRNL rescues METRNL deficiency induced endothelial dysfunction.These findings reveal that METRNL is a new endothelial substance not only determining the circulating METRNL level but also regulating endothelial function for vascular health and disease.METRNL is a therapeutic target against endothelial dysfunction and atherosclerosis. | Sili Zheng Zhiyong Li Jie Song Pin Wang Jian Xu Wenjun Hu Yi Shi Qi Qi Zhuwei Miao Yunfeng Guan Chaoyu Miao | 2023 | Acta Pharmaceutica Sinica B2023，13，4： | 2 |
| 19 | Investigation on color variation of Morpho butterfly wings hierarchical structure based on PCA显示文摘Morpho butterfly wings show brilliant blue color,which has a close relationship with the hierarchical micro/nano structures on the surface of scales.When liquids such as methanol,ethanol and isopropanol with different refractive indexes drop onto the scales,the reflectance of wings would decrease.The main peaks of reflectance shift to the right and the scales turn to yel-low-green.After the liquids volatilizes completely,the scales revert to the original blue color.The typical micro/nano struc-tures of Morpho butterfly wing scales are modeled,and the reflectance variation in the course of dropping liquids is simulated.Furthermore,the principal component analysis(PCA) method is employed to analyze the experimental and simulation reflec-tance data,extract principal components and reduce dimensions.As a result,the curves mapping the reflectance variation are clearly shown in the coordinate system consisting of three principal components.The typical color variation of scales during the dropping process could be monitored,and different kinds of liquids could be obviously distinguished according to the dis-tributed regions of mapping points.This study provides guidance to environmental media detecting as well as data processing,and enhances the fabrication and application of the mimic Morpho butterfly wings micro/nano structures. | JIANG Xuan SHI TieLin ZUO HaiBo YANG XueFeng WU WenJun LIAO GuangLan | 2012 | Science China(Technological Sciences)2012，55，1： | 2 |
