| 1 | Stable classi?cation with limited sample: transferring a 30-m resolution sample set collected in 2015 to mapping 10-m resolution global land cover in 2017显示文摘As the world strives to reduce the impact of population growth, urbanization, agricultural expansion, and climate change on food security, energy and water shortage, resource over-exploration, biodiversity loss, environmental pollution, and ultimately human health, timely and higher resolution land cover information is urgently needed to achieve the sustainable development goals of the United Nations. | Peng Gong Han Liu Meinan Zhang Congcong Li Jie Wang Huabing Huang Nicholas Clinton Luyan Ji Wenyu Li Yuqi Bai Bin Chen Bing Xu Zhiliang Zhu Cui Yuan Hoi Ping Suen Jing Guo Nan Xu Weijia Li Yuanyuan Zhao Jun Yang Chaoqing Yu Xi Wang Haohuan Fu Le Yu Iryna Dronova Fengming Hui Xiao Cheng Xueli Shi Fengjin Xiao Qiufeng Liu Lianchun Song | 2019 | Science Bulletin2019，64，6： | 166 |
| 2 | Qi-Qin Accretionary Belt in Central China Orogen: accretion by trench jam of oceanic plateau and formation of intra-oceanic arc in the Early Paleozoic Qin-Qi-Kun Ocean显示文摘Most orogenic belts have experienced a complex accretionary process with multiple episodes of sea?oor subduction and trench retreat.This accretionary process is important in continenta development and growth[1,2].Three giant orogens extend in China,e.g.,the Central Asian Orogen in the north,the Central China Orogen in the middle and the Himalayan Orogen in the southwest.They are keys for the formation of the Eurasian continent(Fig.1a).The Central China Orogen | Shuguang Song Liming Yang Yuqi Zhang Yaoling Niu Chao Wang Li Su Yanlin Gao | 2017 | Science Bulletin2017，62，15： | 28 |
| 3 | The first all-season sample set for mapping global land cover with Landsat-8 data显示文摘We report the world's first all-season training and validation sample sets for global land cover classification with Landsat-8 data.Prior to this,such samples were only available at a single date primarily from the growing season.It is unknown how much limitation such a single-date sample has to mapping global land cover in other seasons of the year.To answer this question,we selected available Landsat-8 images from four seasons and collected training and validation samples from them.We compared the performances of training samples in different seasons using Random Forest algorithm.We found that the use of training samples from any individual season would result in the best overall classification accuracy when validated by samples in the same season.The global overall accuracy from combined best seasonal results was 67.2% when classifying the 11 Level-1 classes in the Finer Resolution Observation and Monitoring of Global Land Cover(FROM-GLC) classification system.The use of training samples from all seasons(named all-season training sample set hereafter) produced an overall accuracy of 67.0%.We also tested classification within 10° latitude 60° longitude zones using all-season training subsample within each zone and obtained an overall accuracy of 70.2%.This indicates that properly grouped subsamples in space can help improve classification accuracies.All the results in this study seem to suggest that it is possible to use an all-season training sample set to reach global optimality with universal applicability in classifying images acquired at any time of a year for global land cover mapping. | Congcong Li Peng Gong Jie Wang Zhiliang Zhu Gregory S.

| 4 | Comprehensive assessment for removing multiple pollutants by plants in bioretention systems显示文摘Bioretention is a best management practice which uses vegetation to improve the pollutant removal rates in the rain water management.To select the best plant species to remove multiple pollutants in a bioretention system,we tested thirty species of plants in a laboratory in Beijing,China.We found that the ability of the plants to reduce concentrations of heavy metals including cadmium(Cd),lead(Pb),zinc(Zn),and ammonium(NH4?–N)is more than90%.The removal efficiencies for NH4?–N,nitrate(NO3-–N),total phosphorus,and copper(Cu)varied markedly among plant species.The single overall best plant was not easy to be determined.To select the best plant species,we used a dynamic neural network to establish an assessment index system,assessment criteria,and an assessment model that is used here for the first time for multiple pollutants’removal.Applying the theory and model,we discovered that Plantago asiatica L.and Digitaria sanguinalis(L.)Scop.are the overall best plants for removing the seven typicalpollutants.This paper will provide a simple and useful guide for the comprehensive assessment of multiple pollutant removal by plants in complex ecological systems. | Xiaohua Yang Ying Mei Jun He Rong Jiang Yuqi Li Jianqiang Li | 2014 | Chinese Science Bulletin2014，59，13： | 14 |

| 7 | Diamond Raman laser:a promising high-beam-quality and low-thermal-effect laser显示文摘Stimulated Raman-scattering-based lasers provide an effective way to achieve wavelength conversion.However,thermally induced beam degradation is a notorious obstacle to power scaling and it also limits the applicable range where high output beam quality is needed.Considerable research efforts have been devoted to developing Raman materials,with diamond being a promising candidate to acquire wavelength-versatile,high-power,and high-quality output beam owing to its excellent thermal properties,high Raman gain coefficient,and wide transmission range.The diamond Raman resonator is usually designed as an external-cavity pumped structure,which can easily eliminate the negative thermal effects of intracavity laser crystals.Diamond Raman converters also provide an approach to improve the beam quality owing to the Raman cleanup effect.This review outlines the research status of diamond Raman lasers,including beam quality optimization,Raman conversion,thermal effects,and prospects for future development directions. | Yulan Li Jie Ding Zhenxu Bai Xuezong Yang Yuqi Li Jingling Tang Yu Zhang Yaoyao Qi Yulei Wang Zhiwei Lu | 2021 | High Power Laser Science and Engineering2021，9，3： | 7 |

| 9 | Measurement of overburden failure zones in close-multiple coal seams mining显示文摘In the Kaiping Coal field,mining of five coal seams,located within 80 m in the Kailuan Group,#5,#7,#8,#9 and#12 coal seam,is difficult due to small interburden thickness,concentrated stress distributions,high coal seam metamorphism,and complex geological conditions.By using the ZTR12 geological penetration radar(GPR)survey combined with borehole observations,the overburden caving due to mining of the five coals seams was measured.The development characteristics of full-cover rock fractures after mining were obtained from the GPR scan,which provides a measurement basis for the control of rock strata in close multiple coal seam mining.For the first time,it was found that the overburden caving pattern shows a periodic triangular caved characteristic.Furthermore,it is proposed that an upright triangular collapsed pile masonry and an inverted triangular with larger fragments piled up alternately appear in the lower gob.The research results show that the roof structure formed in the gob area can support the key overlying strata,which is beneficial to ensure the integrity and stability of the upper coal seams in multiple-seam mining of close coal seams. | Yang Li Yuqi Ren Syd S.Peng Haozhou Cheng Nan Wang Junbo Luo | 2021 | International Journal of Mining Science and Technology2021，31，1： | 5 |
| 10 | Regulation of phenylpropanoid biosynthesis by MdMYB88 and MdMYB124 contributes to pathogen and drought resistance in apple显示文摘MdMYB88 and MdMYB124 have been demonstrated to be responsible for lignin accumulation in apple under drought stress.In this study,using a metabolomic approach,we identified differentially accumulated phenylpropanoid and flavonoid metabolites in MdMYB88/124 transgenic RNAi plants under control and long-term drought stress conditions in apple roots.We confirmed the regulation of phenylalanine by MdMYB88 and MdMYB124 via UPLC-MS in apple roots under both control and drought conditions.Using Electrophoretic Mobility Shift Assay(EMSA)and ChIPquantitative PCR(qPCR)analyses,we found that MdMYB88 positively regulates the MdCM2 gene,which is responsible for phenylalanine biosynthesis,through binding to its promoter region.Under long-term drought conditions,MdMYB88/124 RNAi plants consistently accumulated increased amounts of H2O2 and MDA,while MdMYB88 and MdMYB124 overexpression plants accumulated decreased amounts of H2O2 and MDA.We also examined the accumulation of metabolites in the phenylpropanoid biosynthesis pathway in the leaves of MdMYB88 and MdMYB124 transgenic apple plants after long-term drought stress.We found that metabolites responsible for plant defense,including phenylpropanoids and flavonoids,accumulated less in the RNAi plants but more in the overexpression plants under both control and drought conditions.We further demonstrated that MdMYB88/124 RNAi plants were more sensitive to Alternaria alternata f.sp.mali and Valsa mali,two pathogens that currently severely threaten apple production.In contrast,MdMYB88 and MdMYB124 overexpression plants were more tolerant to these pathogens.The cumulative results of this study provided evidence for secondary metabolite regulation by MdMYB88 and MdMYB124,further explained the molecular roles of MdMYB88 and MdMYB124 in drought resistance,and provided information concerning molecular aspects of their roles in disease resistance. | Dali Geng Xiaoxia Shen Yinpeng Xie Yusen Yang Ruiling Bian Yuqi Gao Pengmin Li Liying Sun Hao Feng Fengwang Ma Qingmei Guan | 2020 | Horticulture Research2020，7，1： | 5 |
| 11 | Separation process of butanol-butyl acetate-methyl isobutyl ketone system by the analysis to residual curve and the double effect pressure-swing distillation显示文摘The separation of ternary mixture of butanol, butyl acetate, and methyl isobutyl ketone(MIBK) was initially analyzed by the residual curve. In this process, MIBK was chosen as the azeotropic agent during the first step of separation. The optimum mass ratio of extra MIBK was 1.6 in the modified feed stream according to the residual curve. Thus on this condition the top product was butanol-MIBK azeotrope while the bottom product was butyl acetate in the preliminary separation of the mixture. Then the butanol and MIBK azeotrope was separated by the double effect pressureswing distillation with the low pressure column performing at 30 kPa and the atmospheric pressure column at 101 kPa. The optimal operating conditions were then obtained by using Aspen Plus to simulate and optimize the process. The results showed that the mass purities of butanol, butyl acetate, and MIBK were all more than 99% and reached the design requirements. Additionally, compared with the traditional distillation with outside heating, the double effect pressure swing distillation saved the reboiler duty by 48.6% and the condenser duty by 44.6%. | Chunli Li Yuanyuan Song Jing Fang Yang Liu Weiyi Su Yuqi Hu | 2017 | Chinese Journal of Chemical Engineering2017，25，3： | 4 |
| 12 | Hydrolysis of cellobiose catalyzed by zeolites—the role of acidity and micropore structure显示文摘The roles of acidity and micropore structure of zeolite were studied in the hydrolysis of the model oligosaccharide of cellulose–cellobiose. HZSM-5, HY, HMOR and Hβ zeolites were selected as model catalysts for the hydrolysis of cellobiose. The effect of acidity of zeolite, including the strength, type and location, on its catalytic activity was investigated. The strong Br?nsted acid sites located in micropores are the active sites for the hydrolysis of cellobiose to glucose. Meanwhile, the catalytic performance of zeolite is also dependent on the micropore size of zeolite. | Lipeng Zhou Zhen Liu Yuqi Bai Tianliang Lu Xiaomei Yang Jie Xu | 2016 | Journal of Energy Chemistry2016，25，1： | 4 |

| 14 | The cost of obsessive- compulsive disorder (OCD) in China: a multi- center cross- sectional survey based on hospitals显示文摘Background Obsessive-compulsive disorder(OCD)is considered a very debilitating disorder with severe loss of quality of life and income.Aims This study estimates the quality of life and economic consequences of OCD in China.Methods The research team interviewed 639 patients with OCD in 13 hospitals in 12 cities in China.The direct method was used to get the direct cost of OCD.Indirect costs associated with OCD were estimated using the human capital approach.Linear regression analysis was conducted for quality of life and generalised linear model analysis was conducted for total cost.Sensitivity analysis was used to analyse the uncertainty of total cost.Results The mean quality of life score for OCD was 52.78(20.46).The annual total cost of OCD per capita was 24503.78(95%CI:22621.53 to 26386.03)renminbi(RMB)(US$3465.88(95%CI:US$3199.65 to US$3732.11)).The annual cost of OCD in China was estimated to be 37.74 billion(95%CI:34.95 billion to 40.53 billion)RMB(equal to US$5.34 billion(95%CI:US$4.94 billion to US$5.73 billion)).Sensitivity analysis showed that the total annual cost of OCD in China was between 23.15 billion RMB(US$3.27 billion)and 370.00 billion RMB(US$52.33 billion).Worse social function status,more psychiatric symptoms and higher Yale Brown Obsessive-Compulsive Scale(Y-BOCS)score were associated with worse quality of life.The numbers of clinic visits and hospitalisations,socioeconomic status,education,Y-BOCS scores and age were found to be significantly associated with total cost.Conclusions OCD is associated with low quality of life and high costs in China.The findings call for concerted efforts to improve services for patients with OCD.Improvements may include early detection and diagnosis,the provision of evidence-based treatments and relapse prevention strategies. | Weili Yang Zhen Tang Xijin Wang Xiancang Ma Yuqi Cheng Bin Wang Ping Sun Wenxin Tang Jia Luo Changhong Wang Ping Li Guiyun Xu Jun Yan Vlasios Brakoulias Zhen Wang | 2021 | General Psychiatry2021，34，6： | 3 |
| 15 | Shape-controlled synthesis of liquid metal nanodroplets for photothermal therapy显示文摘The capping agents for liquid metal (LM) nanodroplets in aqueous solutions are restricted to thiol-containing and positively-charged molecules or macromolecules.However,both thiolate-metal complex and electrostatic interaction are liable to detachment upon strong mechanical forces such as sonication,leading to limited stability and applications.To address this,we utilized ultrasmall water soluble melanin nanoparticles (MNPs) as the capping agent,which exhibited strong metal binding capability with the oxide layer of gallium based LMs and resulted in enhanced stability.Interestingly,shape-controlled synthesis of LM nanodroplets can be achieved by the incorporation of MNPs.Various EGaln nanostructures including nanorice,nanosphere and nanorod were obtained by simply tuning the feed ratio,sonication time,and suspension temperature.Among these shapes,EGaln nanorice has the best photothermal conversion efficiency,which could be leveraged for photothermal therapy. | Junjie Yan Xudong Zhang Yang Liu Yanqi Ye Jicheng Yu Qian Chen Jinqiang Wang Yuqi Zhang Quanyin Hu Yang Kang Min Yang Zhen Gu | 2019 | Nano Research2019，12，6： | 2 |

| 20 | Liposome-based anchoring and core-encapsulation for combinatorial cancer therapy显示文摘Downregulated pro-apoptotic protein in cancer cells compromises the chemotherapy by a cytotoxic drug.Here,we report co-delivery of a pro-apoptotic protein,caspase 3(Cas 3),and cytotoxic agent,oridonin(ORD),for synergistic cancer treatment,using a method of liposome-based anchoring and core encapsulation.First,ORD is modified with hyaluronic acid(HA)to improve its solubility.Then,the targeted co-delivery system is prepared by assembling the conjugate HA-ORD onto the Cas 3-loaded liposomes,which the surface HA can target the CD44 receptor on cancer cells.In vitro,the co-loaded liposomes(120 nm)are specifically taken up by 4T1 cells and endow a 1.5-fold increase of Cas 3.After intravenous injection into the tumor-bearing mice,the liposomes accumulate in the tumor with high efficacy and significantly inhibit tumor growth via promoting apoptosis and anti-proliferation of cancer cells.Mechanistically,the co-delivery works synergistically by upregulating the activated Cas form,cleaved-Cas 3. | Qingqing Xiao Xiaotong Li Chang Liu Yi Yang Yuqi Hou Ying Wang Mengxiang Su Wei He | 2022 | Chinese Chemical Letters2022，33，9： | 2 |
