| 2 | 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.

| 3 | Western medication plus Traditional Chinese Medicine preparations in patients with chronic heart failure:a prospective,single-blind,randomized,controlled,and multicenter clinical trial显示文摘OBJECTIVE: To assess the efficacy and safety in patients with chronic heart failure(CHF) of Western medication plus Traditional Chinese Medicine(TCM) preparations.METHODS: This prospective, single-blind, randomized, controlled, and multicenter clinical trial began on September 17, 2008, and was completed on June 25, 2011. A total of 340 inpatients, aged 40-79 years, with exacerbating CHF from 10 hospitals were enrolled and randomly allocated within 24 h of admission. The trial included three intervention periods. During hospitalization, the control group received western medication for CHF and the treatment group received Danhong injection with Shenfu injection or Shenmai injection. After discharge,all patients were treated with Qiliqiangxin capsules and Buyiqiangxin tablets or a placebo for 6 months. After the 6-month intervention, both groups received only continuous western medication. The primary endpoint was all-cause mortality.The efficacy assessments were as follows: B-type natriuretic peptide(BNP), Lee's HF score, the 6-minute walking test(6 MWT), left ventricular ejection fraction(LVEF), and the Minnesota Living with Heart Failure Questionnaire(MLHFQ). The safety assessments were as follows: blood and urine routine examination, hepatic and renal function, electrolytes in blood and adverse events.RESULTS: Compared with the control group, the treatment group showed a 30.99% reduction in all-cause mortality and an improved survival rate.The treatment group showed greater improvement in 6 MWT(P = 0.02) than the control group on discharge, after 12-month follow-up, there was a time-group interaction for MLHFQ(P = 0.03). Incidence rate of adverse events and other relevant safety indexes were not statistically significant between the two groups.CONCLUSION: Western medication plus TCM treatment can increase 6-minute walking distance(improve exercise tolerance) and quality of life with heart failure patients. | Wang Xianliang Hou Yazhu Mao Jingyuan Zhao Yingqiang Niu Tianfu Yuan Ruyu Wang Yonggang Cui Jin-rong Shi Le Jia Xiuli Fan Ruihong Lin Qian Zhang Yan Li Zhijun Shang Hongcai Wang Baohe Wang Hongwu Wang Henghe Cui Xiaolei Soh Shanbin Ruan Jishou Zhang Boli | 2017 | Journal of Traditional Chinese Medicine2017，37，6： | 15 |

| 5 | Effect of ultrasonic melt treatment on degassing of Mg-6Zn-1Ca alloy显示文摘The effect of ultrasonic power and treatment time on degassing of Mg-6Zn-1Ca alloy was studied in this paper. The degassing effect was characterized by measuring densities of ingots. The results show that proper ultrasonic treatment can remove hydrogen from the melt of the Mg-6Zn-1Ca alloy. The ultrasonic degassing effect is closely related to the ultrasonic power density and treatment time. The degassing efficiency increases with an increase in ultrasonic power density when the melt is treated at 690 °C for 120 s, reaching its highest value at 1.2 W·cm-3. When the power density is 1.2 W·cm-3, with an increase in ultrasonic treatment time, the degassing efficiency increases at first, reaches its peak value at 120 s, then decreases as the ultrasonic treatment is further prolonged. In this experiment, the optimum degassing effect with an efficiency of 67.5 % is obtained by ultrasonic treatment with the power density of 1.2 W·cm-3 for 120 s. The maximum density of ingot can be increased from 1.8069 g·cm-3 to 1.8146 g·cm-3(increased by 0.43%). | Zheng Jia Wen-ming Zhang Fu Yang Zhi-qiang Zhang Qi-chi Le Jian-zhong Cui | 2015 | China Foundry2015，12，1： | 14 |
| 6 | Effect of homogenization treatment on microstructure evolution and the distributions of RE and Zr elements in various MgeLieREeZr alloys显示文摘Mge3Lie0.4Zr alloys containing RE elements(Gd,La,Nd)(Mge3LieREe0.4Zr alloys)are investigated to reveal the influence of homogenization treatment on microstructures and distributions of RE,Zr elements.It is found that 300C24 h homogenization treatment shows better improvement on the microstructure including the refinement of grain size,the dispersion of cellular dendrite and low melting point particles.Before treatment,La and Nd segregate effectively at grain boundary and Zr segregates in the form of precipitates.Homogenization treatment induces the reduction of RE segregation.However,the segregation of Zr in precipitates cannot be abated due to the relatively low diffusion rate compared with RE elements. | Lei Bao Qichi Le Zhiqiang Zhang Jianzhong Cui Qinxue Li | 2013 | Journal of Magnesium and Alloys2013，1，2： | 10 |
| 7 | A plasmonic route for the integrated wireless communication of subdiffraction-limited signals显示文摘Perfect lenses,superlenses and time-reversal mirrors can support and spatially separate evanescent waves,which is the basis for detecting subwavelength information in the far field.However,the inherent limitations of these methods have prevented the development of systems to dynamically distinguish subdiffraction-limited signals.Utilizing the physical merits of spoof surface plasmon polaritons(SPPs),we demonstrate that subdiffraction-limited signals can be transmitted on planar integrated SPP channels with low loss,low channel interference,and high gain and can be radiated with a very low environmental sensitivity.Furthermore,we show how deep subdiffraction-limited signals that are spatially coupled can be distinguished after line-of-sight wireless transmission.For a visualized demonstration,we realize the high-quality wireless communication of two movies on subwavelength channels over the line of sight in real time using our plasmonic scheme,showing significant advantages over the conventional methods. | Hao Chi Zhang Le Peng Zhang Pei Hang He Jie Xu Cheng Qian Francisco J.Garcia-Vidal Tie Jun Cui | 2020 | Light(Science & Applications)2020，9，1： | 8 |
| 8 | Role of pre-vertical compression in deformation behavior of Mg alloy AZ31B during super-high reduction hot rolling process显示文摘Mg alloy AZ31 B plates were processed by hot rolling with different thickness reductions per pass and prevertical compression followed by super-high reduction hot rolling(PVCR), respectively. Microstructure evolution, rolling formability variation and mechanical responses were investigated. As reduction per pass increased, the number of shear bands deflecting toward rolling direction increased, resulting in easy crack initiation in and around the bands. With increasing reduction per pass up to 80%, twinning and twinning-induced dynamic recrystallization(DRX) dominated the deformation of the edge material at350?C, resulting in local recrystallization with coarse grains and further largest edge-crack degree. Preinduced {10ī12} tensile twins by pre-vertical compression(PVC) increased number density of nucleation sites for dynamic recrystallization during the subsequent severe rolling, which enhanced the dominant role of continuous dynamic recrystallization. Designed PVCR-b was proved to be a relatively effective method to improve rolling formability of rolled Mg alloy AZ31 B plates. With this method, mean grain size of AZ31 B plate was significantly refined from ~600 mm to ~14.1 mm and more homogeneous grain size distribution along transverse direction(TD) was achieved. In addition, basal texture intensity was greatly weakened. As a result, tensile anisotropy was distinctly decreased and fracture elongation increased dramatically. | Weitao Jia Qichi Le Yan Tang Yunpeng Ding Fangkun Ning Jianzhong Cui | 2018 | Journal of Materials Science & Technology2018，34，11： | 8 |
| 9 | Effects of Extrusion Speed on the Microstructure and Mechanical Properties of Mg-9Gd-3Y-1.5Zn-0.8Zr alloy显示文摘The effects of the extrusion speed on the microstructures,mechanical properties and aging hardening behaviors of Mg—9Gd—3Y—1.5Zn—0.8Zr alloy have been investigated.The microstructure evolution during hot extrusion has also been discussed.The microstructures of the extruded alloys mainly consist of the equiaxed dynamically recrystallized grains and fiber-like long period stacking ordered(LPSO)phase.The increasing extrusion speed results in grain coarsening and the mechanical properties deterioration.Meanwhile,it could also retard the aging hardening response.The extrudability of the investigated alloy is limited.Cracks nucleate and grow up rapidly when the extrusion speed is over 0.3 m/min.It should be closely related to the large amount of LPSO phase and the unique microstructure evolution.The rapidly precipitating fine lamella during extrusion could pin the dislocations and grain boundaries effectively.It could strengthen the alloy but also limit the extrudability of the investigated alloy. | Xuan Liu Zhiqiang Zhang Wenyi Hu Qichi Le Lei Bao Jianzhong Cui | 2016 | Journal of Materials Science & Technology2016，32，4： | 7 |
| 10 | 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 (http://gffzzc750bc0108fa4044skxpvx50xqwqb665u.ffgz.tsg.suse.edu.cn/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 |
| 11 | Whole-genome sequencing provides insights into the genetic diversity and domestication of bitter gourd(Momordica spp.)显示文摘Bitter gourd(Momordica charantia)is a popular cultivated vegetable in Asian and African countries.To reveal the characteristics of the genomic structure,evolutionary trajectory,and genetic basis underlying the domestication of bitter gourd,we performed whole-genome sequencing of the cultivar Dali-11 and the wild small-fruited line TR and resequencing of 187 bitter gourd germplasms from 16 countries.The major gene clusters(Bi clusters)for the biosynthesis of cucurbitane triterpenoids,which confer a bitter taste,are highly conserved in cucumber,melon,and watermelon.Comparative analysis among cucurbit genomes revealed that the Bi cluster involved in cucurbitane triterpenoid biosynthesis is absent in bitter gourd.Phylogenetic analysis revealed that the TR group,including 21 bitter gourd germplasms,may belong to a new species or subspecies independent from M.charantia.Furthermore,we found that the remaining 166 M.charantia germplasms are geographically differentiated,and we identified 710,412,and 290 candidate domestication genes in the South Asia,Southeast Asia,and China populations,respectively.This study provides new insights into bitter gourd genetic diversity and domestication and will facilitate the future genomics-enabled improvement of bitter gourd. | Junjie Cui Yan Yang Shaobo Luo Le Wang Rukui Huang Qingfang Wen Xiaoxia Han Nansheng Miao Jiaowen Cheng Ziji Liu Changyuan Zhang Chengcheng Feng Haisheng Zhu Jianwen Su Xinjian Wan Fang Hu Yu Niu Xiaoming Zheng Yulan Yang Dai Shan Zhensheng Dong Weiming He Narinder P.S.Dhillon Kailin Hu | 2020 | Horticulture Research2020，7，1： | 7 |
| 12 | A comparative study of the characteristics of two Coxsackie A virus type 16 strains (genotype B)显示文摘Coxsackie A virus is one of the major pathogens associated with hand, foot and mouth disease (HFMD). The etiological characteristics of Coxsackie A virus type 16 (CA16) are thought to correlate with the pathological process of its infection. Two CA16 strains that were isolated from a severe HFMD patient presented with different plaque forms. This observation, along with biological analysis, indicated that the differences in the strains' biological characteristics, such as proliferation kinetics and immunogenicity, correlate with differences in their pathogenicity toward neonatal mice. Furthermore, these differences are thought to be associated with the sequence of the 5′ non-coding region of the viral genome and the VP1 structural region sequence. The results suggest that the biological and genetic characteristics of the CA16 viral strains are relevant to their pathogenicity. | YANG ErXia ZHAO Heng ZHANG Ying LIU JianSheng LIAO Yun WANG LiChun CUI PingFang YANG LiXian LIU LongDing DONG ChengHong DONG ShaoZhong SHAO CongWen JIANG Li SUN Le LI QiHan | 2012 | Science China(Life Sciences)2012，55，4： | 5 |

| 14 | Active digital spoof plasmonics显示文摘Digital coding and digital modulation are the foundation of modern information science.The combination of digital technology with metamaterials provides a powerful scheme for spatial and temporal controls of electromagnetic waves.Such a technique,however,has thus far been limited to the control of free-space light.Its application to plasmonics to shape subwavelength fields still remains elusive.Here,we report the design and experimental realization of a tunable conformal plasmonic metasurface;which is capable of digitally coding and modulating designer surface plasmons at the deep-subwavelength scale.Based on dynamical switching between two discrete dispersion states in a controlled manner;we achieve digital modulations ofboth amplitude and phase of surface waves with nearly 100%modulation depth on a single device.Our study not only introduces a new approach for active dispersion engineering,but also constitutes an important step towards the realization of subwavelength integrated plasmonic circuits. | Hao Chi Zhang Tie Jun Cui Yu Luo Jingjing Zhang Jie Xu Pei Hang He Le Peng Zhang | 2020 | National Science Review2020，7，2： | 5 |
| 15 | 18β-Glycyrrhetinic acid protects against alpha-naphthylisothiocyanate- induced cholestasis through activation of the Sirt1/FXR signaling pathway显示文摘Cholestasis is a common feature of liver injury, which manifests as bile acid excretion and/or enterohepatic circulation disorders. However, very few effective therapies exist for cholestasis. Recently, 18β-Glycyrrhetinic acid (18b-GA), a major metabolic component of glycyrrhizin, which is the main ingredient of licorice, was reported to protect against alpha-naphthylisothiocyanate (ANIT)-induced cholestasis. However, its protective mechanism remains unclear. We hypothesized that 18b-GA may stimulate the signaling pathway of bile acid (BA) transportation in hepatocytes, resulting its hepatoprotective effect. According to the results, 18b-GA markedly attenuated ANIT-induced liver injury as indicated the hepatic plasma chemistry index and histopathology examination. In addition, the expression levels of nuclear factors, including Sirt1, FXR and Nrf2, and their target efflux transporters in the liver, which mainly mediate bile acid homeostasis in hepatocytes, signi?cantly increased. Furthermore, we first revealed that 18b-GA treatment significantly activated FXR, and which can be significantly reduced by EX-527 (a potent and selective Sirt1 inhibitor), indicating that 18b-GA activates FXR through Sirt1. Taken together, 18b-GA confers hepatoprotection against ANIT-induced cholestasis by activating FXR through Sirt1, which promotes gene expression of the efflux transporter, and consequently attenuates dysregulation of bile acid homeostasis in hepatocyte compartments. | Shou-yan Wu Shi-chao Cui Le Wang Yi-ting Zhang Xiao-xia Yan Heng-lei Lu Guo-zhen Xing Jin Ren Li-kun Gong | 2018 | Acta Pharmacologica Sinica2018，39，12： | 4 |
| 16 | DTI and pathological changes in a rabbit model of radiation injury to the spinal cord after ^(125)I radioactive seed implantation显示文摘Excessive radiation exposure may lead to edema of the spinal cord and deterioration of the nervous system. Magnetic resonance imaging can be used to judge and assess the extent of edema and to evaluate pathological changes and thus may be used for the evaluation of spinal cord injuries caused by radiation therapy. Radioactive ^(125)I seeds to irradiate 90% of the spinal cord tissue at doses of 40–100 Gy(D90) were implanted in rabbits at T_(10) to induce radiation injury, and we evaluated their safety for use in the spinal cord. Diffusion tensor imaging showed that with increased D90, the apparent diffusion coefficient and fractional anisotropy values were increased. Moreover, pathological damage of neurons and microvessels in the gray matter and white matter was aggravated. At 2 months after implantation, obvious pathological injury was visible in the spinal cords of each group. Magnetic resonance diffusion tensor imaging revealed the radiation injury to the spinal cord, and we quantified the degree of spinal cord injury through apparent diffusion coefficient and fractional anisotropy. | Xia Cao Le Fang Chuan-yu Cui Shi Gao Tian-wei Wang | 2018 | Neural Regeneration Research2018，13，3： | 4 |
| 17 | Influence of high-intensity ultrasonic treatment on the phase morphology of a Mg-9.0wt.%Al binary alloy显示文摘The effect of ultrasonic treatment on the β-phase (Mg17Al12) morphology of an Mg-9.0wt.%Al alloy was studied. The result shows that with high-intensity ultrasonic vibration employed during the solidifying of Mg-9.0wt.%Al, the β-phase in the entire cross section of the billet is significantly refined and also changed from continuous to discontinuous morphology. Spherical β-phase is formed during the solidification of the billet treated with high-intensity ultrasonic vibration. | ZHANG Zhiqiang LE Qichi CUI Jianzhong | 2009 | Rare Metals2009，28，1： | 4 |

| 19 | Effects of casting process on microstructures and flow stress behavior of Mg-9Gd-3Y-1.5Zn-0.8Zr semi-continuous casting billets显示文摘Mg-9Gd-3Y-1.5Zn-0.8Zr alloys own high strength,good heat and corrosion resistance.However,it is difficult for the fabrication of large-scale billets,due to the poor deformation ability and strong hot-crack tendency.This work investigated the casting process on the microstructures and flow stress behaviors of the semi-continuous casting billets for the fabrication of large-scale Mg-9Gd-3Y-1.5Zn-0.8Zr billets.The casting process(electromagnetic intensity and casting speed)shows outstanding effects on the microstructures and flow stress behavior of the billets.The billets with the specific casting process(I=68 A,V=65 mm/min)exhibit uniform microstructures and good deformation uniformity. | Xuan liu Qichi Le Zhiqiang Zhang Lei Bao Zhengxing Fan Jianzhong Cui | 2014 | Journal of Magnesium and Alloys2014，2，4： | 3 |
| 20 | A multivariate grey incidence model for different scale data based on spatial pyramid pooling显示文摘In order to solve the problem that existing multivariate grey incidence models cannot be applied to time series on different scales, a new model is proposed based on spatial pyramid pooling.Firstly, local features of multivariate time series on different scales are pooled and aggregated by spatial pyramid pooling to construct n levels feature pooling matrices on the same scale. Secondly,Deng's multivariate grey incidence model is introduced to measure the degree of incidence between feature pooling matrices at each level. Thirdly, grey incidence degrees at each level are integrated into a global incidence degree. Finally, the performance of the proposed model is verified on two data sets compared with a variety of algorithms. The results illustrate that the proposed model is more effective and efficient than other similarity measure algorithms. | ZHANG Ke CUI Le YIN Yao | 2020 | Journal of Systems Engineering and Electronics2020，31，4： | 3 |
