| 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 | Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection. | Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu | 2020 | Science China(Life Sciences)2020，63，3： | 157 |

| 4 | Geological Characteristics and Zircon U-Pb Dating of Volcanic Rocks from the Beizhan Iron Deposit in Western Tianshan Mountains, Xinjiang, NW China显示文摘The Beizhan large iron deposit located in the east part of the Awulale metallogenic belt in the western Tianshan Mountains is hosted in the Unit 2 of the Dahalajunshan Formation as lens, veinlets and stratoid, and both of the hanging wall and footwall are quartz-monzonite; the dip is to the north with thick and high-grade ore bodies downwards. Ore minerals are mainly magnetite with minor sulfides, such as pyrite, pyrrhotite, chalcopyrite and sphalerite. Skarnization is widespread around the ore bodies, and garnet, diopside, wollastonite, actinolite, epidote, uralite, tourmaline sericite and calcite are ubiquitous as gangues. Radiating outwards from the center of the ore body the deposit can be classified into skarn, calcite, serpentinite and marble zones. LA-ICP-MS zircon U-Pb dating of the rhyolite and dacite from the Dahalajunshan Formation indicates that they were formed at 301.3±0.8 Ma and 303.7±0.9 Ma, respectively, which might have been related to the continental arc magmatism during the late stage of subduction in the western Tianshan Mountains. Iron formation is genetically related with volcanic eruption during this interval. The Dahalajunshan Formation and the quartz-monzonite intrusion jointly control the distribution of ore bodies. Both ore textures and wall rock alteration indicate that the Beizhan iron deposit is probably skarn type. | ZHANG Zuoheng HONG Wei JIANG Zongsheng DUAN Shigang XU Lingang LI Fengming GUO Xincheng ZHAO Zhengang | 2012 | Acta Geologica Sinica(English Edition)2012，86，3： | 29 |
| 5 | Critical illness polyneuropathy and myopathy:a systematic review显示文摘Critical illness polyneuropathy and critical illness myopathy are frequent complications of severe illness that involve sensorimotor axons and skeletal muscles,respectively.Clinically,they manifest as limb and respiratory muscle weakness.Critical illness polyneuropathy/myopathy in isolation or combination increases intensive care unit morbidity via the inability or difficulty in weaning these patients off mechanical ventilation.Many patients continue to suffer from decreased exercise capacity and compromised quality of life for months to years after the acute event.Substantial progress has been made lately in the understanding of the pathophysiology of critical illness polyneuropathy and myopathy.Clinical and ancillary test results should be carefully interpreted to differentiate critical illness polyneuropathy/myopathy from similar weaknesses in this patient population.The present review is aimed at providing the latest knowledge concerning the pathophysiology of critical illness polyneuropathy/myopathy along with relevant clinical,diagnostic,differentiating,and treatment information for this debilitating neurological disease. | Chunkui Zhou Limin Wu Fengming Ni Wei Ji Jiang Wu Hongliang Zhang | 2014 | Neural Regeneration Research2014，9，1： | 15 |
| 6 | Large-scale analysis of small RNAs derived from traditional Chinese herbs in human tissues显示文摘Plant-derived microRNAs have recently been reported to function in human blood and tissues. Controversy was immediately raised due to possible contamination and the lack of large sample sizes. Here, we report thousands of unique small RNAs derived from traditional Chinese medicine(TCM) herbs found in human blood cells and mouse lung tissues using a large-scale analysis.We extracted small RNAs from decoctions of 10 TCM plants(Ban Zhi Lian, Chai Hu, Chuan Xin Lian, Di Ding Zi Jin, Huang Qin, Jin Yin Hua, Lian Qiao, Pu Gong Ying, Xia Ku Cao, and Yu Xing Cao) and obtained millions of RNA sequences from each herb. We also obtained RNA-Seq data from the blood cells of humans who consumed herbal decoctions and from the lung tissues of mice administered RNAs from herbal decoctions via oral gavage. We identified thousands of unique small RNA sequences in human blood cells and mouse lung tissues. Some of these identified small RNAs from Chuan Xin Lian and Hong Jing Tian could be mapped to the genomes of the herbs, confirming their TCM plant origin. Small RNAs derived from herbs regulate mammalian gene expression in a sequence-specific manner, and thus are a superior novel class of herbal drug components that hold great potential as oral gene-targeted therapeutics, highlighting the important role of herbgenomics in their development. | Fengming Huang Jianchao Du Zhu Liang Zhichao Xu Jiantao Xu Yan Zhao Yexuan Lin Song Mei Quan He Jindong Zhu Qiang Liu Yanxu Zhang Yuhao Qin Wei Sun Jingyuan Song Shilin Chen Chengyu Jiang | 2019 | Science China(Life Sciences)2019，62，3： | 14 |
| 7 | Group decision-making method based on entropy and experts cluster analysis显示文摘According to the aggregation method of experts' evaluation information in group decision-making,the existing methods of determining experts' weights based on cluster analysis take into account the expert's preferences and the consistency of expert's collating vectors,but they lack of the measure of information similarity.So it may occur that although the collating vector is similar to the group consensus,information uncertainty is great of a certain expert.However,it is clustered to a larger group and given a high weight.For this,a new aggregation method based on entropy and cluster analysis in group decision-making process is provided,in which the collating vectors are classified with information similarity coefficient,and the experts' weights are determined according to the result of classification,the entropy of collating vectors and the judgment matrix consistency.Finally,a numerical example shows that the method is feasible and effective. | Xuan Zhou Fengming Zhang Xiaobin Hui Kewu Li | 2011 | Journal of Systems Engineering and Electronics2011，22，3： | 12 |
| 8 | Wave localization in randomly disordered periodic layered piezoelectric structures显示文摘就联合的 mechnoelectrical 而言,在混乱周期的分层的压电的结构的嘘波浪的本地化被学习。在对层正常、正切的方向宣传的波浪被考虑。在二个连续单位房间之间的转移矩阵根据连续性条件被获得。在混乱周期的结构的本地化因素和本地化长度的表情被介绍。为混乱周期的压电的结构,本地化因素和本地化长度的数字结果被介绍并且讨论。它能从结果被看见频率通带和站乐队为订的周期的结构出现,波浪本地化现象发生在混乱的周期的,并且变化的系数越大,波浪本地化的度是越多 greater。当连续压电的材料的性质是类似的,当某个材料参数有大变化时,站乐队的间隔变得更宽广时,在订的周期的结构的站乐队的宽度是很狭窄的。为在方向正常宣传到层的波浪,本地化长度在频率上有更少的依赖,要不是在对层正切的方向宣传本地化长度的波浪强烈依赖于频率。 | Fengming Li Yuesheng Wang Chao Hu Wenhu Huang | 2006 | Acta Mechanica Sinica2006，22，6： | 11 |
| 9 | The Coix Genome Provides Insights into Panicoideae Evolution and Papery Hull Domestication显示文摘Coix is a grass crop domesticated as early as the Neolithic era.It is still widely cultivated for both highly nutritional food and medicinal use.However,the genetic study and breeding of this crop are hindered by the lack of a sequenced genome.Here,we report de novo sequencing and assembly of the 1619-Mb genome of Coix,and annotation of 75.39%repeats and 39629 protein-coding genes.Comparative genomics analysis showed that Coix is more closely related to sorghum than maize,but intriguingly only Coix and maize had a recent genome duplication event,which was not detected in sorghum.We further constructed a genetic map and mapped several important traits,especially the strength of hull.Selection of papery hull(thin:easy dehulling)from the stony hull(thick:difficult dehulling)in wild progenitors was a key step in Coix domestication.The papery hull makes seed easier to process and germinate.Anatomic and global transcriptome analysis revealed that the papery hull is a result of inhibition of cell division and wall biogenesis.We also successfully demonstrated that seed hull pressure resistance is controlled by two major quantitative trait loci(QTLs),which are associated with hull thickness and color,respectively.The two QTLs were further fine mapped within intervals of 250 kb and 146 kb,respectively.These resources provide a platform for evolutionary studies and will facilitate molecular breeding of this important crop. | Chao Guo Yanan Wang Aiguo Yang Jun He Chaowen Xiao Shanhua Lv Fengming Han Yibing Yuan Yuan Yuan Xiaolong Dong Juan Guo YawenYang-Hailan Liu Ningzhi Zuo Yaxi Hu Kangxu Zhao Zhengbo Jiang Xing Wang Tingting Jiang Yaou Sherf Moju Cao Yuan Wang Zhaobo Long Tingzhao Rong Luqi Huang Shufeng Zhou | 2020 | Molecular Plant2020，13，2： | 11 |

| 11 | Soil Aggregate Stability and Iron and Aluminium Oxide Contents Under Different Fertiliser Treatments in a Long-Term Solar Greenhouse Experiment显示文摘Soil in greenhouses is likely to suffer a gradual decline in aggregate stability. Determination of the effects of different fertiliser practices on soil aggregate stability is important for taking advantage of solar greenhouses. Soil aggregate stability and iron(Fe) and aluminium(Al) oxide contents were investigated in a 26-year long-term fertilisation experiment in greenhouse in Shenyang, China,under eight fertiliser treatments: manure(M), fertiliser N(FN), fertiliser N with manure(MN), fertiliser P(FP), fertiliser P with manure(MP), fertiliser NP(FNP), fertiliser NP with manure(MNP), and control without any fertiliser(CK). A wet sieving method was used to determine aggregate size distribution and water-stable aggregates(WSA), mean weight diameter and geometric mean diameter as the indices of soil aggregate stability. Different fertiliser treatments had a statistically significant influence on aggregate stability and Fe and Al oxide contents. Long-term application of inorganic fertilisers had no obvious effects on the mass proportion of aggregates. By contrast, manure application significantly increased the mass proportion of macroaggregates at the expense of microaggregates. All treatments, with the exception of FNP, significantly increased the stability of macroaggregates but decreased that of microaggregates when compared with CK. Aggregation under MP and MN was better than that under M and MNP; however,no significant differences were found among inorganic fertiliser treatments(i.e., FN, FP, and FNP). A positive relation was found between pyrophosphate-extractable Fe and WSA(r = 0.269), but no significant relations were observed between other Fe and Al oxides and aggregate stability. | YIN Yan WANG Li LIANG Chenghua XI Fengming PEI Zhongjian DU Liyu | 2016 | Pedosphere2016，26，5： | 11 |
| 12 | Origin and accumulation of high-maturity oil and gas in deep parts of the Baxian Depression, Bohai Bay Basin, China显示文摘Great quantities of light oil and gas are produced from deep buried hill reservoirs at depths of 5,641 m to 6,027 m and 190 °C to 201 °C in the Niudong-1 Well, representing the deepest and hottest commercial hydrocarbons discovered in the Bohai Bay Basin in eastern China. This discovery suggests favorable exploration prospects for the deep parts of the basin. However, the discovery raises questions regarding the genesis and accumulation of hydrocarbons in deep reservoirs. Based on the geochemical features of the hydrocarbons and characteristics of the source rocks as well as thermal simulation experiments of hydrocarbon generation, we conclude that the oil and gas were generated from the highly mature Sha-4 Member (Es4 ) source rocks instead of thermal cracking of crude oils in earlier accumulations. The source kitchen with abnormal pressures and karsted carbonate reservoirs control the formation of high-maturity hydrocarbon accumulations in the buried hills (i.e., Niudong-1) in conjunction with several structural-lithologic traps in the Es4 reservoirs since the deposition of the upper Minghuazhen Formation. This means the oil and gas exploration potential in the deep parts of the Baxian Depression is probably high. | Zhao Xianzheng Jin Qiang Jin Fengming Ma Peng Wang Quan Wang Jing Ren Chunling Xi Qiuling | 2013 | Petroleum Science2013，10，3： | 10 |
| 13 | Application of Land-use Change Model in Guiding Regional Planning:A Case Study in Hun-Taizi River Watershed,Northeast China显示文摘This paper firstly investigated the land-use and land-cover change (LUCC) in the Hun-Taizi River watershed, Northeast China from 1988 to 2004 based on remotely sensed images and geographic information systems (GIS) technology. Then, using the famous land-use change model of Conversion of Land Use and its Effects at Small regional extent (CLUE-S), this paper simulated the land use changes under historical trend (HT), urban planning (UP) and ecological protection (EP) scenarios considering urban planning and ecological protection over the next 20 years. The simulated results under UP scenario in 2020 were compared with the planning map to assess the feasibility of using land-use change model to guide regional planning. Results show that forest land, dry farmland, paddy, and shrub land were the main land-use categories. Paddy and dry farmland being converted to urban area and rural settlement characterized the land-use change from 1988 to 2004. The main land-use categories changed over time. Landscape-pattern fragmentation will be worse under HT and UP scenarios, but better in EP scenario. The comparing results of simulated map with planning map in 2020 show that land-use change model is powerful tool to guide regional planning. Land-use scenarios can support regional planning and policy-making through analyzing future consequences scientifically. | LIU Miao HU Yuanman ZHANG Wei ZHU Junjun CHEN Hongwei XI Fengming | 2011 | Chinese Geographical Science2011，21，5： | 10 |

| 15 | Vast laminated diatom mat deposits from the west low-latitude Pacific Ocean in the last glacial period显示文摘Diatoms are one of the predominant contributors to global carbon fixation by accounting for over 40% of total oceanic primary production and dominate export production. They play a significant role in marine biogeochemistry cycle. The diatom mat deposits are results of vast diatoms bloom. By analysis of diatom mats in 136°00′―140°00′E,15°00′―21°00′N, Eastern Philippines Sea, we identified the species of the diatoms as giant Ethmodiscus rex (Wallich) Hendey. AMS 14C dating shows that the sediments rich in diatom mats occurred during 16000―28600 a B.P., which means the bloom mainly occurred during the last glacial period, while there are no diatom mat deposits in other layers. Preliminary analysis indicates that Antarctic Intermediate Water (AAIW) expanded northward and brought silicate-rich water into the area, namely, silicon leakage processes caused the bloom of diatoms. In addition, the increase of iron input is one of the main reasons for the diatom bloom. | ZHAI Bin LI TieGang CHANG FengMing CAO QiYuan | 2009 | Chinese Science Bulletin2009，54，23： | 9 |
| 16 | Palaeoenvironmental changes from pollen record in deep sea core PC-1 from northern Okinawa Trough,East China Sea during the past 24 ka显示文摘A pollen record of core PC-1 from the northern Okinawa Trough,East China Sea(ECS),provides information on vegetation and climate changes since 24 cal.kaBP.A total of 103 samples were palynologically analyzed at 8 cm intervals with a time resolution of 230 a.Four pollen zones are recognized:zone I(812―715 cm,24.2―21.1 cal.kaBP),zone II(715―451 cm,21.1―15.2 cal.kaBP),zone III(451―251 cm,15.2―10.8 cal.kaBP),zone IV(251―0 cm,10.8―0.3 cal.kaBP),corresponding to Late MIS 3,Last Glacial Maximum(LGM),deglaciation and Holocene,respectively.The LGM is characterized by the dominance of herbs,mainly Artemisia,and high pollen influx,implying an open vegetation on the exposed continental shelf and a cool and dry climate.The deglaciation is a climate warming stage with Pinus percentage increased and Artemisia percentage decreased and a rapid sealevel rise.The Holo-cene is characterized by predominance of tree pollen with rapid increase in Castanea-Castanopsis in-dicating the development of mixed evergreen and deciduous broad-leaved forest and a warm,humid climate.Low pollen influx during the Holocene probably implies submergence of the continental shelf and retreat of the pollen source area.The vegetation indicated by pollen assemblage found in this upper zone is consistent with the present vegetation found in Kyushu,Japan.Originating from the humid mountain area of North Luzon of the Philippines,Tasmania and New Zealand,Phyllocladus with sporadic occurrence throughout PC-1 core probably suggests the influence of Palaeo-Kuroshio Current or intense summer monsoon.The observed changes in Pinus and Herbs percentage indicate fluctuations of the sea level,and high Pinus percentage corresponds to high sea level.Spectrum analysis of the pollen percentage record reveals many millennial-scale periodicities,such as periodicities of 6.8,3.8,2.2,1.6 ka. | XU HongYan CHANG FengMing LUO YunLi SUN XiangJun | 2009 | Chinese Science Bulletin2009，54，20： | 9 |
| 17 | Characteristics analysis of a novel centralized-driving flip-flow screen显示文摘During screening operation, blinding or clogging of screen perforations generally occurs to reduce the sieving capacity and efficiency. Recently, the flip-flow screening has been widely recognized as a feasible method to deal with the problem. In this paper, a novel centralized-driving flip-flow screen(CFS) was developed for the separation of fine and moist coal, and the key structures, namely, a centralized-driving mechanism and a quasi-circle beam mounted with the mat were designed for high reliability and stability. By means of a test on an experimental prototype, the effect of some factors, i.e., initial stretch and hardness of the polyurethane panel, respectively, and the rotation speed of the driving motor on the kinematic characteristic of the screen surface was investigated. Results show that without an initial stretch, the sieve mat generates the largest vibratory amplitude while the slacker the sieve mat initially is, the smaller amplitude it will accomplish. And an increase in the rotation speed could cause a rise in the vibratory amplitude. Unlike the two factors, the hardness does not have a definite effect on the kinematic performance, on which a further study is required. Finally, screening processing on a laboratory prototype was conducted to draw the conclusion that the developed CFS also has a high sieving efficiency for the fine and moist coal. | Peng Liping Li Fengming Dong Hailin Liu Chusheng Zhao Yuemin Duan Chenlong | 2014 | International Journal of Mining Science and Technology2014，24，2： | 9 |

| 19 | ACTIVE VIBRATION CONTROL OF FINITE L-SHAPED BEAM WITH TRAVELLING WAVE APPROACH显示文摘In this paper,the disturbance propagation and active vibration control of a finite L-shaped beam are studied.The dynamic response of the structure is obtained by the travelling wave approach.The active vibration suppression of the finite L-shaped beam is performed based on the structural vibration power flow.In the numerical calculation,the influences of the near field effect of the error sensor and the small error of the control forces on the control results are all considered.The simulation results indicate that the structural vibration response in the medium and high frequency regions can be effectively computed by the travelling wave method.The effect of the active control by controlling the power flow is much better than that by controlling the acceleration in some cases.And the control results by the power flow method are slightly affected by the locations of the error sensor and the small error of the control forces. | Chunchuan Liu Fengming Li1 Wenhu Huang(P.O.Box 137,School of Astronautics,Harbin Institute of Technology,Harbin 150001,China) | 2010 | Acta Mechanica Solida Sinica2010，23，5： | 8 |
| 20 | Tuning of band gaps for a two-dimensional piezoelectric phononic crystal with a rectangular lattice显示文摘In this paper,the elastic wave propagation in atwo-dimensional piezoelectric phononic crystal is studiedby considering the mechanic-electric coupling.The gener-alized eigenvalue equation is obtained by the relation of themechanic and electric fields as well as the Bloch-Floquet the-orem.The band structures of both the in-plane and anti-planemodes are calculated for a rectangular lattice by the plane-wave expansion method.The effects of the lattice constantratio and the piezoelectricity with different filling fractionsare analyzed.The results show that the largest gap width isnot always obtained for a square lattice.In some situations,a rectangular lattice may generate larger gaps.The band gapcharacteristics are influenced obviously by the piezoelectric-ity with the larger lattice constant ratios and the filling frac-tions. | Yize Wang Fengming Li Yuesheng Wang Kikuo Kishimoto Wenhu Huang | 2009 | Acta Mechanica Sinica2009，25，1： | 8 |
