1Effects of water management on arsenic and cadmium speciation and accumulation in an upland rice cultivar显示文摘Pot and field experiments were conducted to investigate the effects of water regimes on the speciation and accumulation of arsenic(As) and cadmium(Cd) in Brazilian upland rice growing in soils polluted with both As and Cd. In the pot experiment constant and intermittent flooding treatments gave 3–16 times higher As concentrations in soil solution than did aerobic conditions but Cd showed the opposite trend. Compared to arsenate, there were more marked changes in the arsenite concentrations in the soil solution as water management shifted, and therefore arsenite concentrations dominated the As speciation and bioavailability in the soil. In the field experiment As concentrations in the rice grains increased from 0.14 to 0.21 mg/kg while Cd concentrations decreased from 0.21 to 0.02 mg/kg with increasing irrigation ranging from aerobic to constantly flooding conditions. Among the various water regimes the conventional irrigation treatment produced the highest rice grain yield of 6.29 tons/ha. The As speciation analysis reveals that the accumulation of dimethylarsinic acid(from 11.3% to 61.7%) made a greater contribution to the increase in total As in brown rice in the intermittent and constant flooding treatments compared to the intermittent-aerobic treatment. Thus, water management exerted opposite effects on Cd and As speciation and bioavailability in the soil and consequently on their accumulation in the upland rice. Special care is required when irrigation regime methods are employed to mitigate the accumulation of metal(loid)s in the grain of rice grown in soils polluted with both As and Cd.Pengjie Hu Younan Ouyang Longhua Wu Libo Shen Yongming Luo Peter Christie 2015Journal of Environmental Sciences2015,27,1:43

3Sharing Clinical Trial Data: A Proposal from the International Committee of Medical Journal Editors显示文摘The International Committee of Medical Journal Editors (ICMJE) believes that there is an ethical obligation to responsibly share data generated by interventional clinical trials because participants have put themselves at risk.In a growing consensus,many funders around the world-foundations,government agencies,and industry-now mandate data sharing.Here,we outline ICMJE's proposed requirements to help meet this obligation.We encourage feedback on the proposed requirements.Anyone can provide feedback at www.icmje.org by April 18,2016.Darren B Taichman Joyce Backus Christopher Baethge Howard Bauchner Peter W de Leeuw Jeffrey M Drazen John Fletcher Frank Frizelle Irish Groves Abraham Haileamlak Astrid James Christine Laine Larry Peiperl Anja Pinborg Peush Sahni Si-Nan Wu 2016Chinese Medical Journal2016,,2:20
4How Could Agricultural Land Systems Contribute to Raise Food Production Under Global Change?显示文摘To feed the increasing world population,more food needs to be produced from agricultural land systems.Solutions to produce more food with fewer resources while minimizing adverse environmental and ecological consequences require sustainable agricultural land use practices as supplementary to advanced biotechnology and agronomy.This review paper,from a land system perspective,systematically proposed and analyzed three interactive strategies that could possibly raise future food production under global change.By reviewing the current literatures,we suggest that cropland expansion is less possible amid fierce land competition,and it is likely to do less in increasing food production.Moreover,properly allocating crops in space and time is a practical way to ensure food production.Climate change,dietary shifts,and other socio-economic drivers,which would shape the demand and supply side of food systems,should be taken into consideration during the decision-making on rational land management in respect of sustainable crop choice and allocation.And finally,crop-specific agricultural intensification would play a bigger role in raising future food production either by increasing the yield per unit area of individual crops or by increasing the number of crops sown on a particular area of land.Yet,only when it is done sustainably is this a much more effective strategy to maximize food production by closing yield and harvest gaps.WU Wen-bin YU Qiang-yi Verburg H Peter YOU Liang-zhi YANG Peng TANG Hua-jun 2014Journal of Integrative Agriculture2014,13,7:19

6A Survey of Image Synthesis and Editing with Generative Adversarial Networks显示文摘This paper presents a survey of image synthesis and editing with Generative Adversarial Networks(GANs). GANs consist of two deep networks, a generator and a discriminator, which are trained in a competitive way. Due to the power of deep networks and the competitive training manner, GANs are capable of producing reasonable and realistic images, and have shown great capability in many image synthesis and editing applications.This paper surveys recent GAN papers regarding topics including, but not limited to, texture synthesis, image inpainting, image-to-image translation, and image editing.Xian Wu Kun Xu Peter Hall 2017Tsinghua Science and Technology2017,22,6:14
7Spatio-Temporal Changes in the Rice Planting Area and Their Relationship to Climate Change in Northeast China: A Model-Based Analysis显示文摘Rice is one of the most important grain crops in Northeast China(NEC)and its cultivation is sensitive to climate change.This study aimed to explore the spatio-temporal changes in the NEC rice planting area over the period of 1980-2010 and to analyze their relationship to climate change.To do so,the CLUE-S(conversion of land use and its effects at small region extent)model was first updated and used to simulate dynamic changes in the rice planting area in NEC to understand spatio-temporal change trends during three periods:1980-1990,1990-2000 and 2000-2010.The changing results in individual periods were then linked to climatic variables to investigate the climatic drivers of these changes.Results showed that the NEC rice planting area expanded quickly and increased by nearly 4.5 times during 1980-2010.The concentration of newly planted rice areas in NEC constantly moved northward and the changes were strongly dependent on latitude.This confirmed that climate change,increases in temperature in particular,greatly influenced the shift in the rice planting area.The shift in the north limit of the NEC rice planting area generally followed a 1°C isoline migration pattern,but with an obvious time-lag effect.These findings can help policy makers and crop producers take proper adaptation measures even when exposed to the global warming situation in NEC.XIA Tian WU Wen-bin ZHOU Qing-bo YU Qiang-yi Peter H Verburg YANG Peng LU Zhong-jun TANG Hua-jun 2014Journal of Integrative Agriculture2014,13,7:12

10Electroacupuncture improves microcirculation and neuronal morphology in the spinal cord of a rat model of intervertebral disc extrusion显示文摘Most studies on spinal cord neuronal injury have focused on spinal cord tissue histology and the expression of nerve cell damage and repair-related genes. The importance of the microcirculation is often ignored in spinal cord injury and repair research. Therefore, in this study, we established a rat model of intervertebral disc extrusion by inserting a silica gel pad into the left ventral surface of T13. Electroacupuncture was used to stimulate the bilateral Zusanli point(ST36) and Neiting point(ST44) for 14 days. Compared with control animals, blood flow in the first lumbar vertebra(L1) was noticeably increased in rats given electroacupuncture. Microvessel density in the T13 segment of the spinal cord was increased significantly as well. The number of normal neurons was higher in the ventral horn of the spinal cord. In addition, vacuolation in the white matter was lessened. No obvious glial cell proliferation was visible. Furthermore, hindlimb motor function was improved significantly. Collectively, our results suggest that electroacupuncture can improve neuronal morphology and microcirculation, and promote the recovery of neurological functions in a rat model of intervertebral disc extrusion.Dai-xun Jiang Zhi-song Lu Ge-bin Li Sheng-yong Sun Xiang Mu Peter Lee Wu Chen 2015Neural Regeneration Research2015,10,2:9
11Adsorption and desorption characteristics of diphenylarsenicals in two contrasting soils显示文摘Diphenylarsinic acid(DPAA) is formed during the leakage of aromatic arsenic chemical weapons in soils,is persistent in nature,and results in arsenic contamination in the field.The adsorption and desorption characteristics of DPAA were investigated in two typical Chinese soils,an Acrisol(a variable-charge soil) and a Phaeozem(a constant-charge soil).Their thermodynamics and some of the factors influencing them(i.e.,initial pH value,ionic strength and phosphate) were also evaluated using the batch method in order to understand the environmental fate of DPAA in soils.The results indicate that Acrisol had a stronger adsorption capacity for DPAA than Phaeozem.Soil DPAA adsorption was a spontaneous and endothermic process and the amount of DPAA adsorbed was affected significantly by variation in soil pH and phosphate.In contrast,soil organic matter and ionic strength had no significant effect on adsorption.This suggests that DPAA adsorption may be due to specific adsorption on soil mineral surfaces.Therefore,monitoring the fate of DPAA in soils is recommended in areas contaminated by leakage from chemical weapons.Anan Wang Shixin Li Ying Teng Wuxin Liu Longhua Wu Haibo Zhang Yujuan Huang Yongming Luo Peter Christie 2013Journal of Environmental Sciences2013,25,6:8
12Allogeneic Vγ9Vδ2 T-cell immunotherapy exhibits promising clinical safety and prolongs the survival of patients with late-stage lung or liver cancer显示文摘Vγ9Vδ2 T cells are promising candidates for cellular tumor immunotherapy.Due to their HLA-independent mode of action,allogeneic Vγ9Vδ2 T cells can be considered for clinical application.To apply allogeneic Vγ9Vδ2 T cells in adoptive immunotherapy,the methodology used to obtain adequate cell numbers with optimal effector function in vitro needs to be optimized,and clinical safety and efficacy also need to be proven.Therefore,we developed a novel formula to improve the expansion of peripheralγδT cells from healthy donors.Then,we used a humanized mouse model to validate the therapeutic efficacy of expandedγδT cells in vivo;furthermore,the expandedγδT cells were adoptively transferred into late-stage liver and lung cancer patients.We found that the expanded cells possessed significantly improved immune effector functions,including proliferation,differentiation,and cancer cell killing,both in vitro and in the humanized mouse model.Furthermore,a phase I clinical trial in 132 late-stage cancer patients with a total of 414 cell infusions unequivocally validated the clinical safety of allogeneic Vγ9Vδ2 T cells.Among these 132 patients,8 liver cancer patients and 10 lung cancer patients who received≥5 cell infusions showed greatly prolonged survival,which preliminarily verified the efficacy of allogeneic Vγ9Vδ2 T-cell therapy.Our clinical studies underscore the safety and efficacy of allogeneic Vγ9Vδ2 T-cell immunotherapy,which will inspire further clinical investigations and eventually benefit cancer patients.Yan Xu Zheng Xiang Mohammed Alnaggar Léonce Kouakanou Jiawei Li Junyi He Jiashuang Yang Yi Hu Yan Chen Li Lin Jianlei Hao Jingxia Li Jibing Chen Man Li Qingling Wu Christian Peters Qinghua Zhou Jianshuang Li Yingqing Liang Xiaohua Wang Baohui Han Meili Ma Dieter Kabelitz Kecheng Xu Wenwei Tu Yangzhe Wu Zhinan Yin 2021Cellular & Molecular Immunology2021,18,2:8
13Interpretation of Climate Change and Agricultural Adaptations by Local Household Farmers: a Case Study at Bin County, Northeast China显示文摘Although climate change impacts and agricultural adaptations have been studied extensively,how smallholder farmers perceive climate change and adapt their agricultural activities is poorly understood.Survey-based data(presents farmers’personal perceptions and adaptations to climate change)associated with external biophysical-socioeconomic data(presents real-world climate change)were used to develop a farmer-centered framework to explore climate change impacts and agricultural adaptations at a local level.A case study at Bin County(1980s-2010s),Northeast China,suggested that increased annual average temperature(0.6°C per decade)and decreased annual precipitation(46 mm per decade,both from meteorological datasets)were correctly perceived by 76 and 66.9%,respectively,of farmers from the survey,and that a longer growing season was confirmed by 70%of them.These reasonably correct perceptions enabled local farmers to make appropriate adaptations to cope with climate change:Longer season alternative varieties were found for maize and rice,which led to a significant yield increase for both crops.The longer season also affected crop choice:More farmers selected maize instead of soybean,as implicated from survey results by a large increase in the maize growing area.Comparing warming-related factors,we found that precipitation and agricultural disasters were the least likely causes for farmers’agricultural decisions.As a result,crop and variety selection,rather than disaster prevention and infrastructure improvement,was the most common ways for farmers to adapt to the notable warming trend in the study region.YU Qiang-yi WU Wen-bin LIU Zhen-huan Peter H Verburg XIA Tian YANG Peng LU Zhong-jun YOU Liang-zhi TANG Hua-jun 2014Journal of Integrative Agriculture2014,13,7:8
14Low-noise 1.3 μm InAs/GaAs quantum dot laser monolithically grown on silicon显示文摘We report low-noise, high-performance single transverse mode 1.3 μm InAs/GaAs quantum dot lasers monolithically grown on silicon(Si) using molecular beam epitaxy. The fabricated narrow-ridge-waveguide Fabry–Perot(FP) lasers have achieved a room-temperature continuous-wave(CW) threshold current of 12.5 mA and high CW temperature tolerance up to 90°C. An ultra-low relative intensity noise of less than-150 dB∕Hz is measured in the 4–16 GHz range. Using this low-noise Si-based laser, we then demonstrate 25.6 Gb/s data transmission over13.5 km SMF-28. These low-cost FP laser devices are promising candidates to provide cost-effective solutions for use in uncooled Si photonics transmitters in inter/hyper data centers and metropolitan data links.MENGYA LIAO SIMING CHEN ZHIXIN LIU YI WANG LALITHA PONNAMPALAM ZICHUAN ZHOU JIANG WU MINGCHU TANG SAMUEL SHUTTS ZIZHUO LIU PETER M.SMOWTON SIYUAN YU ALWYN SEEDS HUIYUN LIU 2018Photonics Research2018,,11:7

16863 genomes reveal the origin and domestication of chicken显示文摘Despite the substantial role that chickens have played in human societies across the world,both the geographic and temporal origins of their domestication remain controversial.To address this issue,we analyzed 863 genomes from a worldwide sampling of chickens and representatives of all four species of wild jungle fowl and each of the five subspecies of red jungle fowl(RJF).Our study suggests that domestic chickens were initially derived from the RJF subspecies Gallus gallus spadiceus whose present-day distribution is predominantly in southwestern China,northern Thailand and Myanmar.Following their domestication,chickens were translocated across Southeast and South Asia where they interbred locally with both RJF subspecies and other jungle fowl species.In addition,our results show that the White Leghorn chicken breed possesses a mosaic of divergent ancestries inherited from other subspecies of RJF.Despite the strong episodic gene flow from geographically divergent lineages of jungle fowls,our analyses show that domestic chickens undergo genetic adaptations that underlie their unique behavioral,morphological and reproductive traits.Our study provides novel insights into the evolutionary history of domestic chickens and a valuable resource to facilitate ongoing genetic and functional investigations of the world's most numerous domestic animal.Ming-Shan Wang Mukesh Thakur Min-Sheng Peng Yu Jiang Laurent Alain Francois Frantz Ming Li Jin-Jin Zhang Sheng Wang Joris Peters Newton Otieno Otecko Chatmongkon Suwannapoom Xing Guo Zhu-Qing Zheng Ali Esmailizadeh Nalini Yasoda Hirimuthugoda Hidayat Ashari Sri Suladari Moch Syamsul Arifin Zein Szilvia Kusza Saeed Sohrabi Hamed Kharrati-Koopaee Quan-Kuan Shen Lin Zeng Min-Min Yang Ya-Jiang Wu Xing-Yan Yang Xue-Mei Lu Xin-Zheng Jia Qing-Hua Nie Susan Joy Lamont Emiliano Lasagna Simone Ceccobelli Humpita Gamaralalage Thilini Nisanka Gunwardana Thilina Madusanka Senasige Shao-Hong Feng Jing-Fang Si Hao Zhang Jie-Qiong Jin Ming-Li Li Yan-Hu Liu Hong-Man Chen Cheng Ma Shan-Shan Dai Abul Kashem Fazlul Haque Bhuiyan Muhammad Sajjad Khan Gamamada Liyanage Lalanie Pradeepa Silva Thi-Thuy Le Okeyo Ally Mwai Mohamed Nawaz Mohamed Ibrahim Megan Supple Beth Shapiro Olivier Hanotte Guojie Zhang Greger Larson Jian-Lin Han Dong-Dong Wu Ya-Ping Zhang 2020Cell Research2020,30,8:7

18Concentrations of Heavy Metals in Suburban Horticultural Soils and Their Uptake by Artemisia selengensis显示文摘A total of 222 surface soil samples and 40 plant samples were collected to investigate the spatial distribution and possible sources of soil heavy metals and to know the uptake and translocation of heavy metals from roots to different plant parts in a representative vegetable production area in the Baguazhou Island, a suburb of Nanjing City, East China. The arithmetic mean values of total Cd, Cr,Cu, Ni, Pb, and Zn concentrations in the soils were 0.314, 133, 41.0, 58.0, 31.8, and 114 mg kg-1, respectively. All of these values were above the topsoil background values in the Nanjing area. Multivariate and geostatistical analyses showed that soil Cd contamination was derived mainly from agricultural practices. In contrast, Cu and Zn were derived mainly from soil parent materials and Pb from atmospheric deposition from highway gasoline stations. Artemisia selengensis, a locally important specialty vegetable, accumulated heavy metals primarily in the edible leaves. The general distribution of heavy metal concentrations in this plant species showed that the highest occurred in the leaves, intermediate in the stems and lowest in the roots. Cd had the highest concentration factor(root-to-soil ratio) and may pose increased health risks in the future to the local population through the consumption of contaminated vegetables.CUI Xu SUN Xulei HU Pengjie YUAN Cheng LUO Yongming WU Longhua Peter CHRISTIE 2015Pedosphere2015,25,6:6

20ESR Dating of the Evolution of the Shuanghu Basin in the Northern Tibetan Plateau显示文摘The Shuanghu basin is a NE-trending rift basin bounded by NE-striking normal faults and NW-striking shear-extensional faults of the northern Tibetan Plateau. Four samples from calcite veins in marginal faults and one sample from mudstone (S-3) were collected for dating the evolution of the Shuanghu basin by using the ESR spectrograph of EXM-type. Ages were calculated according to the close-equilibrium model on the basis of the measured ESR signal spectra of samples, providing good chronological information. It is known from the ESR dating that the extensional faulting and rifting of the Shuanghu area began at 4.92 Ma B.P., followed by regional folding in 3.56-1.36 Ma, NW-striking faulting in 0.60 Ma and normal faulting in 0.024 Ma in the Shuanghu basin.WU Zhenhan JIANG Wan Peter Blisniuk BI Siwen ZHANG Shukun Olaf Kuchel MAO Yi 1999Acta Geologica Sinica(English Edition)1999,73,3:6
