| 1 | Dual origins of Xiaoqinling gold-bearing quartz veins:Fluid inclusion evidence显示文摘Fluid inclusion research in Archean metamorphic rocks, Yanshanian granite and gold-bearing quartz veins shows that regional metamorphic fluids are high temperature and high saline, Yanshanian post-granitic fluids are CO2-bearing low saline, and ore-forming fluids are also CO2-rich low saline. In gold-barren/free parts of quartz veins in gold deposits, daughter mineral-bearing high saline inclusions related with metamorphic fluids remained. This proclaims quartz veins hosting gold ores might have been formed in early metamorphism, and overlapped or mineralized by late Yanshanian gold-bearing fluids. | Hongrui Fan Yihan Xie Rui Zhao Yinglan Wang | 2000 | Chinese Science Bulletin2000，45，15： | 17 |
| 2 | Zircon U-Pb dating of basement gneisses in the super-large Bayan Obo REE-Fe-Nb deposit, Inner Mongolia显示文摘Zircon U-Pb ages have been determined for basement gneisses in the Bayan Obo REE-Fe-Nb deposit. On the U-Pb concordia diagram data of three samples yield up-per intercept ages of 1948-1917 Ma. Thus, these basement gneisses are of Paleoproterozoic. Rock association of these basement gneisses includes tonalite, syenite and paragneiss, not belonging to a sedimentary package. It is more appro-priate to consider this association as a basement complex rather than a stratigraphic 'Group'. | WANG Kaiyi FAN Hongrui XIE Yihan LI Huimin | 2002 | Chinese Science Bulletin2002，47，3： | 16 |
| 3 | Application of Smith Predictor Based on Single Neural Network in Cold Rolling Shape Control显示文摘Flatness is one of the most important criterion factors to evaluate the quality of the steel strip. To improve the strip’s flatness quality, the most frequently used methodology is to employ the closed-loop automatic shape control system. However, in the shape control system, the shape-meter is always installed at the down way of the exit of the cold rolling mill and can not sense the changes of the strip flatness in the rolling gap directly. This kind of installation results in the delay of the feedback in the control system. Therefore, the stability and response performance of the system are strongly affected by the delay. At present, there is still no mature way to design controllers for systems with time delay. Although the conventional PID controller used in most practical applications has the capability to compensate the delay, the effect of the compensation is limited, especially for the systems with long time delay. Smith predictor, as a compensator for solving this problem, is now widely used in industry systems. However, the request of highly precise model of the system and the poor adaptive performance to the changes of related parameters limit the application of the Smith predictor in practice. In order to overcome the drawbacks of the Smith predictor, a new Smith predictor based on single neural network PID (SNN-PID) is proposed. Because the single neural network is employed into the Smith predictor to improve the controller’s self-adaptability, the adaptive capability to the varying parameters of the system is improved. Meanwhile, for the purpose of solving the problems such as time-consuming and complicated calculation of the neural networks in real time, the learning coefficient of neural network is divided into several stages as usually done in expert control system. Therefore, the control system can obtain fast response due to the improved calculation speed of the neural networks. In order to validate the performance of the proposed controller, the experiment is conducted on the shape control system in a 300 mm four-high reversing cold rolling mill. The experimental results show that the SNN-PID with Smith predictor controller can effectively compensate the delay effects and achieve better control performance than the conventional PID controller. | WANG Yiqun SUN FD LIU Jian SUN Menghui XIE Yihan | 2009 | Chinese Journal of Mechanical Engineering2009，22，2： | 14 |
| 4 | Surface acoustic wave humidity sensors based on uniform and thickness controllable graphene oxide thin films formed by surface tension显示文摘Graphene oxide(GO)is a promising candidate for humidity sensing,and the uniformity and thickness of GO films are important for the reproducibility and test signal strength of humidity sensors.In this paper,uniform and thicknesscontrollable GO films are first formed by the surface tension of different concentrations of GO solution and then transferred to surface acoustic wave(SAW)humidity sensors.This GO film formation and transfer process has very good repeatability and stability,as evidenced by the humidity response of the sensors.With the help of the uniform and highly oxidized GO film,the humidity sensors show a significantly high sensitivity(absolute sensitivity of 25.3 kHz/%RH and relative sensitivity of 111.7 p.p.m./%RH)in a wide test range from 10%RH to 90%RH with very little hysteresis(<1%RH).The sensors achieve good reversibility,excellent short-term repeatability and stability.Moreover,the humidity sensors also show a fast response and recovery time of<10 s. | Xianhao Le Yihan Liu Li Peng Jintao Pang Zhen Xu Chao Gao Jin Xie | 2019 | Microsystems & Nanoengineering2019，5，1： | 4 |

| 7 | CNT@leather-based electronic bidirectional pressure sensor显示文摘The ability of perceiving external pressures and conducting corresponding signals is one of the important functions of flexible electronics,which has been widely studied in electronic skin,prosthetics,robotics,healthcare,human-machine interfaces,etc.Pressure sensor should not be limited to the detection of unidirectional pressure.Here,a leather-based electronic pressure sensor and corresponding arrays with bidirectional sensing capability are demonstrated.The sensor/arrays consisting of two pieces of stacked leather both modified with acidified carbon nanotubes(a-CNTs)can achieve multi-level response to pressure over a broad working range and sense pulling force opposite to pressure.With polyurethane mixed with ferriferrous oxide(Fe3O4)powder being applied to their upper surface,the resistive sensor/individual units of arrays can also detect the magnetic field because of the contactless pulling force generated by the magnetized Fe3O4.Being able to sense pressure,pulling force and magnetic field,the leather-based electronic bidirectional pressure sensor and corresponding arrays with good performance not only exhibit potential for mass production and their broad application prospects,but also provide a new insight for the development of flexible electronics. | CHEN Yuan Yuan XIE RuiJie ZOU BingHua LIU YiHan ZHANG Kang LI Sheng ZHENG Bing ZHANG WeiNa WU JianSheng HUO Feng | 2020 | Science China(Technological Sciences)2020，63，10： | 1 |
| 8 | Genome-wide identification and expression analysis of NtbHLH gene family in tobacco(Nicotiana tabacum)and the role of NtbHLH86 in drought adaptation显示文摘The bHLH transcription factors play pivotal roles in plant growth and development,production of secondary metabolites and responses to various environmental stresses.Although the bHLH genes have been well studied in model plant species,a comprehensive investigation of the bHLH genes is required for tobacco with newly obtained high-quality genome.In the present study,a total of 309 NtbHLH genes were identified and can be divided into 23 subfamilies.The conserved amino acids which are essential for their function were predicted for the NtbHLH proteins.Moreover,the NtbHLH genes were conserved during evolution through analyzing the gene structures and conserved motifs.A total of 265 NtbHLH genes were localized in the 24 tobacco chromosomes while the remained 44 NtbHLH genes were mapped to the scaffolds due to the complexity of tobacco genome.Moreover,transcripts of NtbHLH genes were obviously tissue-specific expressed from the gene-chip data from 23 tobacco tissues,and expressions of 20 random selected NtbHLH genes were further confirmed by quantitative real-time PCR,indicating their potential functions in the plant growth and development.Importantly,overexpressed NtbHLH86 gene confers improve drought tolerance in tobacco indicating that it might be involved in the regulation of drought stress.Therefore,our findings here provide a valuable information on the characterization of NtbHLH genes and further investigation of their functions in tobacco. | Ge Bai Da-Hai Yang Peijian Chao Heng Yao MingLiang Fei Yihan Zhang Xuejun Chen Bingguang Xiao Feng Li Zhen-Yu Wang Jun Yang He Xie | 2021 | Plant Diversity2021，43，6： | 1 |
| 9 | Risk factors and a prediction model for sepsis: A multicenter retrospective study in China显示文摘Background:Sepsis is typically associated with poor outcomes.There are various risk factors and predictive mod-els for sepsis based on clinical indicators.However,these models are usually predictive of all critical patients.This study explored the risk factors for 28-day outcomes of patients with sepsis and developed a prognosis prediction model.Methods:This was a multicenter retrospective analysis of sepsis patients hospitalized in three intensive care units(ICUs)from September 1st 2015,to June 30th 2020.Demographic,clinical history,and laboratory test data were extracted from patient records.Investigators explored the risk factors affecting 28-day sepsis prognosis by univariate analysis.The effects of confounding factors were excluded by multivariate logistic regression analysis,and new joint predictive factors were calculated.A model predicting 28-day sepsis prognosis was constructed through data processing analysis.Results:A total of 545 patients with sepsis were included.The 28-day mortality rate was 32.3%.Risk factors including age,D-dimer,albumin,creatinine,and prothrombin time(PT)were predictive of death from sepsis.The goodness-of-fit value for this prediction model was 0.534,and the area under the receiver operating characteristic curve was 0.7207.Further analysis of the immune subgroups(n=140)revealed a significant decrease in CD3+,CD4+CD8-,and CD4+CD29+memory effector T lymphocytes and an increase in CD56+natural killer(NK)cells in the hypoalbuminemia group compared with the normal albumin group(65.5 vs.58.3,P=0.005;41.2 vs.32.4,P=0.005;21.8 vs.17.1,P=0.029;12.6 vs.17.6,P=0.004).Conclusions:Risk factors for 28-day sepsis mortality include age,D-dimer,creatinine,PT,and albumin.A decrease in albumin level may exacerbate immunosuppression in patients with sepsis.This study establishes a prediction model based on these indicators,which shows a good degree of calibration and differentiation.This model may provide good predictive value for clinical sepsis prognosis. | Ming Li Peijie Huang Weiwei Xu Zhigang Zhou Yun Xie Cheng Chen Yihan Jiang Guangqing Cui Qi Zhao Ruilan Wang | 2022 | Journal of Intensive Medicine2022，2，3： | 1 |

| 13 | A novel monoacylglycerol lipase-targeted^(18)F-labeled probe for positron emission tomography imaging of brown adipose tissue in the energy network显示文摘Monoacylglycerol lipase(MAGL)constitutes a serine hydrolase that orchestrates endocannabinoid homeostasis and exerts its function by catalyzing the degradation of 2-arachidonoylglycerol(2-AG)to arachidonic acid(AA).As such,selective inhibition of MAGL represents a potential therapeutic and diagnostic approach to various pathologies including neurodegenerative disorders,metabolic diseases and cancers.Based on a unique 4-piperidinyl azetidine diamide scaffold,we developed a reversible and peripheral-specific radiofluorinated MAGL PET ligand[^(18)F]FEPAD.Pharmacokinetics and binding studies on[^(18)F]FEPAD revealed its outstanding specificity and selectivity towards MAGL in brown adipose tissue(BAT)–a tissue that is known to be metabolically active.We employed[^(18)F]FEPAD in PET studies to assess the abundancy of MAGL in BAT deposits of mice and found a remarkable degree of specific tracer binding in the BAT,which was confirmed by post-mortem tissue analysis.Given the negative regulation of endocannabinoids on the metabolic BAT activity,our study supports the concept that dysregulation of MAGL is likely linked to metabolic disorders.Further,we now provide a suitable imaging tool that allows non-invasive assessment of MAGL in BAT deposits,thereby paving the way for detailed mechanistic studies on the role of BAT in endocannabinoid system(ECS)-related pathologies. | Ran Cheng Masayuki Fujinaga Jing Yang Jian Rong Ahmed Haider Daisuke Ogasawara Richard S.Van Tuo Shao Zhen Chen Xiaofei Zhang Erick R.Calderon Leon Yiding Zhang Wakana Mori Katsushi Kumata Tomoteru Yamasaki Lin Xie Shaofa Sun Lu Wang Chongzhao Ran Yihan Shao Benjamin Cravatt Lee Josephson Ming-Rong Zhang Steven H.Liang | 2022 | Acta Pharmacologica Sinica2022，43，11： | 0 |
| 14 | Packing Adjustment Towards High Mobility Luminescent Conjugated Polymers显示文摘Next generation display and lighting technology calls for thinner,cheaper and more-flexible unit devices.Polymer light emitting transistor(PLET),which integrates logic function of organic field effect transistor(OFET),luminescence function of organic light emitting diode(OLED),and potential mechanical properties,is believed to be the raising star in this field.However,great challenges remain in developing the core materials of PLETs,which simultaneously require the integration of high ambipolar mobility and strong solid-state luminescence properties.Herein,high mobility luminescent thienopyrroledione-benzodiathiadiazole-fluorene-based conjugated polymer was chosen as polymer backbone,and polymers TBT-1 and TBT-2(TBT=thienopyrroledione-benzodiathiadiazole-thienopyrrole-dione)with red luminescence were obtained by direct arylation polymerization(DArP).By introducing linear alkyl side chains,the packing orientation is changed from face-on in TBT-1 thin film to edge-on in TBT-2 thin film,which is beneficial for improving the field effect performance.The average hole and electron mobility of TBT-2 are 1.1×10^(-2)and 2.0×10^(-3)cm^(2)·V^(-1)·s^(-1),respectively.This work provides new design strategy for high mobility luminescent conjugated polymers,which can be used in PLETs. | ZHANG Yihan LIU Qingqing GAO Can XIE Ziyi HU Beining DONG Huanli | 2023 | Chemical Research in Chinese Universities2023，39，5： | 0 |
| 15 | Boosting the energy density of aqueous MXene-based supercapacitor by integrating 3D conducting polymer hydrogel cathode显示文摘The wide-spread proliferation of aqueous MXene-based supercapacitor has been largely shadowed by the limited cell potential window(typically in the range of 0-0.6 V).To address this baffling issue,designing asymmetric supercapacitor(ASC)is proposed as a rational strategy to enlarge the potential window(thus energy density)of individual cell in aqueous electrolytes.To this date,however,it still remains a great challenge to develop easy fabricating,3D nanostructured,and pseudocapacitive cathode materials that can perfectly match with MXene anodematerials.In this work,we propose a supramolecular strategy to construct conducting polymer hydrogel(CPH)with highly interconnected 3D nanostructures and large pseudocapacitance,which can finely match with 2D Ti_(3)C_(2)T_(x).The as-assembled CPH//Ti_(3)C_(2)T_(x) ASCwith CPH cathode and MXene anode can operate in a broadened potential window of 1.15 V in aqueous PVA/H_(2)SO_(4) gel electrolyte with remarkably improved energy density of 16.6μWh/cm^(2)(nine times higher than that of symmetric MXene supercapacitor).Additionally,this ASC exhibits outstanding cyclic stability with no trackable performance decay over 30,000 galvanostatic charge and discharge cycles.It is demonstrated in this work that employing positive CPH electrode is a feasible yet promising strategy to enhance the potential window and energy density of aqueous MXene supercapacitors. | Xiang Chu Yihan Wang Lucheng Cai Haichao Huang Zhong Xu Yanting Xie Cheng Yan Qing Wang Haitao Zhang Hong Li Weiqing Yang | 2022 | SusMat2022，2，3： | 0 |

| 17 | Deep seabed mining:Frontiers in engineering geology and environment显示文摘Ocean mining activities have been ongoing for nearly 70 years,making great contributions to industrialization.Given the increasing demand for energy,along with the restructuring of the energy supply catalyzed by efforts to achieve a low-carbon economy,deep seabed mining will play an important role in addressing energy-and resource-related problems in the future.However,deep seabed mining remains in the exploratory stage,with many challenges presented by the high-pressure,low-temperature,and complex geologic and hydrodynamic environments in deep-sea mining areas,which are inaccessible to human activities.Thus,considerable efforts are required to ensure sustainable,economic,reliable,and safe deep seabed mining.This study reviews the latest advances in marine engineering geology and the environment related to deep-sea min-ing activities,presents a bibliometric analysis of the development of ocean mineral resources since the 1950s,summarizes the development,theory,and issues related to techniques for the three stages of ocean mining(i.e.,exploration,extraction,and closure),and discusses the engineering geology environment,geological disasters,in-situ monitoring techniques,envi-ronmental protection requirements,and environmental effects in detail.Finally,this paper gives some key conclusions and future perspectives to provide insights for subsequent studies and commercial mining operations. | Xingsen Guo Ning Fan Yihan Liu Xiaolei Liu Zekun Wang Xiaotian Xie Yonggang Jia | 2023 | International Journal of Coal Science & Technology2023，10，2： | 0 |
| 18 | Comparison of two end-member styles of epithermal Au-(Cu)deposits显示文摘EPITHERMA Au-(Cu) deposits occur largely in volcano-plutonic arcs (island arcs as well as continentalarcs) associated with subduction zones, with ages similar to those of volcanism. These deposits form atshallow depth,<1 km, and are hosted mainly by volcanic rocks. Modern volcanic-hydrothermal systems provide an analogue to the environment for the ancient intrusion-related and volcanic epithermal deposits. Recent studies also indicate that the volcanic epithennalore deposits are formed from magmatic fluids, although the magmatic signatures have been largely erasedby meteoric water. At depth (fig. 1), the magmatic fluid from the high-level intrusive magma will result in the formation of intrusion-related deposits (e.g. porphyry Cu, Au, Mo deposits). Detailed studies of fluid inclusions and stable isotopes indicate that the hydrothermal system that form these deposits are initially | FAN Hongrui and XIE Yihan Institute of Geology, Chinese Academy of Sciences, Beijing 100029, China | 1999 | Chinese Science Bulletin1999，44，S2： | 0 |
| 19 | Systematic review on the adverse reactions of oral administration of Indigo Naturalis and its preparations显示文摘Objective:This article systematically analyses the effects of adverse drug events/adverse drug reactions(ADEs/ADRs)of oral Indigo Naturalis(Qingdai)preparations in order to provide references for its rational clinical application.Methods:All clinical studies reporting ADE/ADR related to the oral administration of Qingdai preparations were searched through electronic databases,including PubMed,the Cochrane Library,Embase,China National Knowledge Infrastructure(CNKI),China Biology Medicine disc(CBM),VIP Information Chinese Journal Service Platform(VIP),and Wanfang database,from inception to September 27,2020.Information were extracted from these literatures,including primary disease,type of adverse reactions,dose,treatment,outcomes and so on.Incidence of ADE/ADR was estimated,as well as distribution of primary diseases and victim organs and systems were analyzed.Results:A total of 682 articles were included,with 651 clinical population studies and 31 case reports.Among them,604 detailed ADR/AE involving 33459 patients using oral Qingdai preparations,and a total of 5061 cases were found to present adverse events,including 2827 cases of digestive system(abdominal pain,diarrhea,etc.),469 cases of blood system damage(thrombocytopenia,leukopenia,anemia,etc.),313 cases of liver damage(abnormal liver function,liver toxicity,elevated liver enzymes,etc.),327 cases of nervous system reactions(headache,dizziness,poor sleep,etc.)and 1186 cases of other systems and organs.Severe adverse events(SAEs)mainly were liver damage,and could be relived after symptomatic treatment.Conclusion:From the systematic information retrieval and analysis,it is found that oral Qingdai preparations application may clinically cause ADEs/ADRs in terms of gastrointestinal tract and liver damage.Therefore,when using oral Qingdai preparations,liver and stomach protection should be done.At the same time,pay close attention to various biochemical indicators and the patient's drug response during the treatment process,and,if necessary,deal with it in time so as not to deteriorate the condition.Moreover,active surveillance system should be conducted to monitor ADE/ADR,so as to establish a clearer causal relationship between the drug and the adverse event. | Xueyi Deng Rui Lan Qianwen Xie Jingmin Xiao Jiaqi Lai Jing Chen Yihan He Shaonan Liu Lihong Yang Xinfeng Guo | 2021 | TMR Modern Herbal Medicine2021，4，1： | 0 |
