| 1 | Discovery of ultrahigh-pressure magnesite-bearing garnet lherzolite (>3.8 GPa) in the Altyn Tagh, Northwest China显示文摘Magnesite-bearing garnet Iherzolite from the Altyn Tagh, associated with garnet pyroxenite, and garnet-bearing felsic gneiss, crops out as lenses in Proterozoic gneiss about 100 km east of the Jianggelasayi River. The garnet Iherzolite, together with the eclogite in western Jianggelasayi, composes a high-pressure to ultrahigh-pressure metamorphic belt in the southern margin of the Altyn Tagh. Parageneses of minerals from magnesite-bearing garnet Iherzolite indicate that the rock evolved a multi-stage metamorphism. The peak-stage metamorphism produces an assemblage of Grt+Ol+Opx+Cpx±Mgs, in which A12O3 content of Opxis very low (0.30-0.66wt%). The calculated P-T condition of the peak stage is 3.8-5.lGPa and 880-970°C, some exsolution rods of clinopyroxene and rutile occur in the Grt and magnesite is rimed by dolomite and orthopyroxene, all implying that the peak stage was a UHP metamorphic process.

| 2 | High-precision timing of the Quaternary standard samples with thermal ionization mass spectrometry (TIMS) U-series method显示文摘Two national stalagmite standard (GBW04412, GBW04413) and one international coral standard (RKM4) have been determined by using thermal ionization mass spectrometry (TIMS) method. The values of ( 234 U/ 238 U) act , ( 230 Th/ 234 U) act and age are all consistent in error range with the standard values obtained by using α spectrometry. | Peng Zicheng Wang Zhaorong Sun Weidong Ma Zhibang Xia Ming Zhang Chenhui Chen Wenji Zhang Zhonglu An Zhisheng | 1998 | Chinese Science Bulletin1998，43，4： | 14 |
| 3 | A new compensation current real-time computing method for power active filter based on double linear construction algorithm显示文摘Considering the detection principle that “when load current is periodic current, the integral in a cycle for absolute value of load current subtracting fundamental active current is the least”, harmonic current real-time detection methods for power active filter are proposed based on direct computation, simple iterative algorithm and optimal iterative algorithm. According to the direct computation method, the amplitude of the fundamental active current can be accurately calculated when load current is placed in stable state. The simple iterative algorithm and the optimal iterative algorithm provide an idea about judging the state of load current. On the basis of the direct computation method, the simple itera- tive algorithm, the optimal iterative algorithm and precise definition of the basic concepts such as the true amplitude of the fundamental active current when load current is placed in varying state, etc., the double linear construction idea is proposed in which the amplitude of the fundamental active current at the moment of the sample is accurately calculated by using the first linear construction and the condition which disposes the next sample is created by using the second linear construction. On the basis of the double linear con- struction idea, a harmonic current real-time detection method for power active filter is proposed based on the double linear construction algorithm. This method has the char- acteristics of small computing quantity, fine real-time performance, being capable of ac- curately calculating the amplitude of the fundamental active current and so on. | LI Zicheng SUN Yukun | 2006 | Science China(Technological Sciences)2006，49，4： | 8 |
| 4 | Osmium isotope determination on mantle-derived peridotite xenoliths from Panshishan with N-TIMS显示文摘The 187Os/ 188Os ratios of spinel lherzolite xenoliths from Panshishan determined with N-TIMS are lower than that of the primitive mantle, which shows depleted mantle characteristics. Their positive correlation with Al-2O-3/MgO suggests that the geochemical behavior of trace elements Re and Os is similar to that of Al-2O-3 and MgO respectively during the magmatic evolution and Re-Os isotopic system is largely immune to mantle metasomatism. A model age of 2 8-3 4 Ga obtained by 187Os/ 188Os-Al-2O-3/MgO correlation might represent the homogeneous age of the mantle lithosphere beneath the area. | Weidong Sun Zicheng Peng Xiachen Zhi Daogong Chen Zhaorong Wang Xinhua Zhou | 1998 | Chinese Science Bulletin1998，43，7： | 7 |
| 5 | High-precision U-series dating of Holocene corals from South China Sea by thermal ionization mass spectrometry(TIMS)显示文摘Using the isotopic diluting and thermal ionization mass spectrometric (TIMS) technique, the U-series dating procedure was established on the basis of measurement of national standard GBW04412. With this highly precise technique the Holocene corals from the South China Sea were dated. Comparison between this method and α-spectrometry was made. The results show that a thriving period of corals in the South China Sea appeared at 6 800—5 800 a BP, during which the paleosea level was the higher than at present in the Holecene. | Zhibang Ma Ming Xia Chenghui Zhang Zicheng Pen Zhaorong Wang Weidong Sun Zhisheng An | 1999 | Chinese Science Bulletin1999，44，10： | 4 |
| 6 | High-precision uranium-series dating of lacustrine carbonates from Daihai Lake显示文摘Ages of small aragonite samples retrieved from sediments from the Daihai Lake are determined by using the Thermal Ionization Mass Spectrometry (TIMS) technique. The ages of the samples range from (8740±601) to (10446±489) a, with a precision of 2%-3% for non-corrected dating ages and 4.7%-9.8% for corrected ages respectively, and are consistent within the deviation range. At about 10.5 ka BP, the grain-size of the sediments coarsens sharply, the frequency curves of grain-size distribution show coarse grain dominated single-double kurtosis, indicating cooling, decreased hydrodynamic conditions and increased wind influence procedure. This is in good agreement with previous results obtained from the Daihai Lake, which suggests that the climate was cold and the lake surface was shrinking. The TIMS ages of the sediments are therefore believed to be credible. | SUN Qianli ZHOU Jie PENG Zicheng LIU Weiguo Xiao Jule | 2001 | Chinese Science Bulletin2001，46，7： | 3 |
| 7 | Os isotopic composition of the earth's primitive upper mantle显示文摘The osmium isotopic ratio of 187Os/ 188Os ranging from 0.126 to 0.127 for the primitive upper mantle (PUM) is obtained according to the correlation between 187Os/ 188Os and Al 2O 3 of mantle-derived xenoliths and orogenic peridotites, which consists with Allegre and Luck’s ALM value and similar to Yin’s nuggets uniform reservoir (NUR) value. It shows that the Os isotope ratio is lower than enstatite or ondinary chondrites, similar to carbonaceous chondrites (CV3). | Weidong Sun Xiachen Zhi Zicheng Peng Zhaorong Wang Ningjie Ge Xinhua Zhou | 1998 | Chinese Science Bulletin1998，43，18： | 3 |
| 8 | The potent roles of salt-inducible kinases(SIKs)in metabolic homeostasis and tumorigenesis显示文摘Salt-inducible kinases(SIKs)belong to AMP-activated protein kinase(AMPK)family,and functions mainly involve in regulating energy response-related physiological processes,such as gluconeogenesis and lipid metabolism.However,compared with another well-established energy-response kinase AMPK,SIK roles in human diseases,especially in diabetes and tumorigenesis,are rarely investigated.Recently,the pilot roles of SIKs in tumorigenesis have begun to attract more attention due to the finding that the tumor suppressor role of LKB1 in non-small-cell lung cancers(NSCLCs)is unexpectedly mediated by the SIK but not AMPK kinases.Thus,here we tend to comprehensively summarize the emerging upstream regulators,downstream substrates,mouse models,clinical relevance,and candidate inhibitors for SIKs,and shed light on SIKs as the potential therapeutic targets for cancer therapies. | Zicheng Sun Qiwei Jiang Jie Li Jianping Guo | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 1 |

| 10 | Optimization of fracture reduction robot controller based on improved sparrow algorithm显示文摘The accuracy of a fracture reduction robot(FRR)is critical for ensuring the safety of surgery.Improving the repositioning accuracy of a FRR,reducing the error,and realizing a safer and more stable folding motion is critical.To achieve this,a sparrow search algorithm(SSA)based on the Levy flight operator was proposed in this study for self-tuning the robot controller parameters.An inverse kinematic analysis of the FRR was also performed.The robot dynamics model was established using Simulink,and the inverse dynamics controller for the fracture reduction mechanism was designed using the computed torque control method.Both simulation and physical experiments were also performed.The actual motion trajectory of the actuator drive rod and its error with a desired trajectory was obtained through simulation.An optimized Levy-sparrow search algorithm(Levy-SSA)crack reduction robot controller demonstrated an overall reduction of two orders of magnitude in the reduction error,with an average error reduction of 98.74%compared with the traditional unoptimized controller.The Levy-SSA increased the convergence of the crack reduction robot control system to the optimal solution,improved the accuracy of the motion trajectory,and exhibited important implications for robot controller optimization. | Baichuan An Jianwen Chen Hao Sun Minghuan Yin Zicheng Song Chao Zhuang Cheng Chang Minghe Liu | 2023 | Biomimetic Intelligence & Robotics2023，3，4： | 1 |
| 11 | Study of Star-Delta Soft Switch to Extend AC Motor High Speed Operation Region显示文摘In traction application,speed range of motor is an important index for motor drives.In AC motor control,the maximum speed of the motor is limited by the output voltage capability of the traditional three-phase inverter with star connenction of windings.Switching the star connection to delta connection in high-speed range can extend the speed range.In order to extend the speed operation region,star-delta switch proposed by many literatures relies on mechanical relay,which needs a dead zone of tens of milliseconds and seriously affects torque output.Besides,the traditional method will cause current overshoot during the switch transient process,decreasing the device security and reliability.Aiming at the defects existing in the star-delta hard switching,this paper proposes a star-delta soft switching method.Without adding extra power electronics devices,DC-bus capacitor is used to provide the path of zero axis current in the transient process,which helps to achieve the smooth torque output and zero current switch in the transient.Experiments have been done to validate the performance of the proposed method.The switching transient from star to delta connection in the motor drive can be much more stable than hard switching method. | Yixuan Shuai Dong Jiang Zhuo Chen Zicheng Liu Haijing Sun Peng Li | 2023 | CES Transactions on Electrical Machines and Systems2023，7，3： | 0 |
| 12 | Whole-exome sequencing reveals genetic underpinnings of salivary adenoid cystic carcinoma in the Chinese population显示文摘Salivary gland carcinomas(SGCs)are rare malignancies that remain poorly understood owing to their low incidence(Matsuba et al.,1986b;Liu et al.,2012).As per GLOBOCAN 2018.52.800 new cancers arising from salivary glands were estimated to be diag-nosed across the world that year.Because of their high propensity to invade local and perineural structures. | Shuhang Wang Yue Yu Yuan Fang Huiyao Huang Dawei Wu Hong Fang Ying Bai Chao Sun Anqi Yu Qi Fan Zicheng Yu Chao Zhang Changxi Wang Zaixian Tai Yi Huang Ning Li | 2020 | Journal of Genetics and Genomics2020，47，7： | 0 |
| 13 | Petroleum exploration breakthrough and geological significance in Cretaceous Yingcheng and Denglouku formations of Shuangcheng area, northern Songliao Basin, NE China显示文摘Based on drilling geological,geochemical,geophysical and production test data,the characteristics of source rocks,reservoir rocks and caprocks,as well as the process of hydrocarbon generation,trap evolution and oil accumulation of the oil-bearing assemblage composed of the Cretaceous Yingcheng Formation(K1yc)and Denglouku Formation(K1d)in the Shuangcheng area,northern Songliao Basin,NE China,were analyzed by using the research methods for petroleum systems.The source rocks mainly exist in K1yc,with the organic matters mainly originated from lower aquatic organisms and algae,and reaching the grade of high-quality source rock in terms of organic abundance.The crude oil,which is characterized by low density,high freezing point and high wax content,is believed to have generated by the K1yc source rocks.The reservoir rocks include K1d sandstones and K1yc glutenites.The mudstone in the fourth member of K1d serves as the direct caprock of the oil reservoir.The oil was generated during the period between Yaojia Formation and Nenjiang Formation,and then accumulated during the periods of Nenjiang Formation and Paleogene–Neogene.The traps evolved in three stages:the late Yingcheng Formation,the late Quantou Formation and the late Nenjiang Formation,forming structural and structural-lithologic reservoirs.It is concluded that good source-reservoir-caprock assemblage,late hydrocarbon charging,short migration distance and stable tectonic setting are favorable factors for the formation of oil reservoirs. | LIU Chao FU Xiaofei LI Yangcheng WANG Haixue SUN Lidong LU Jiamin LI Junhui SUN Youhai SHI Lidong HU Huiting YUAN Hongqi YANG Zicheng | 2023 | Petroleum Exploration and Development2023，50，1： | 0 |
| 14 | Chemical Composition of the Primitive Mantle Source of Peridotite Inclusions at Mount Lianshan, Liuhe County,Jiangsu Province显示文摘This paper presents a study of the major and trace element compositions of fresh mantle-derived spinel lherzolite and harzburgite inclusions from Cenozoic alkaline basalt in Mount Lianshan and Mount Panshi, Liuhe County, Jiangsu Province. An estimation is made of the contents of the major elements and some of the trace elements in the primitive mantle source region of the area, from which the authors have obtained MgO/Al2O3= 7.86. The contents of MgO and Al2O3 are also obtained as 37.58% and 4.78% respectively based on the correlation of MgO-Al2O3. Then, the contents of various elements in the primitive mantle are calculated using their regression equations with MgO, and the compositor) of the primitive mantle, a basic issue in geochemistry study, is discussed on that basis. | SUN Weidong PENG Zicheng CHEN Daogong ZHI Xiachen WANG Zhaorong GE Ningjie | 1998 | Acta Geologica Sinica(English Edition)1998，72，2： | 0 |
| 15 | Chondroitin Polymerizing Factor (CHPF) promotes cell proliferation and tumor growth in human osteosarcoma by inhibiting SKP2's ubiquitination while activating the AKT pathway显示文摘Osteosarcoma is a common malignant tumor occurring in children and young adults. Chondroitin sulfate (CS) participates in cell adhesion, cell division, and the formation of neural networks in the body, the biosynthesis of which requires the participation of glycosyltransferases. CHPF, a glycosyltransferase, plays a role in the extension of CS. Recently, CHPF's biological roles and functional importance in human diseases including malignant tumors have been widely discussed. However, whether CHPF is involved in osteosarcoma development and growth has not been revealed. The present work aimed to investigate the expression levels, functional significance and molecular mechanism of CHPF in osteosarcoma progression. Our results revealed that CHPF is strongly expressed in osteosarcoma tissues and cells. Furthermore, CHPF serves as a tumor promoter in the development and progression of osteosarcoma through enhancing cell proliferation and migration while suppressing apoptosis. Exploration of the mechanism by which CHPF promotes osteosarcoma indicated that CHPF promotes osteosarcoma through counteracting SKP2's ubiquitination and activating the Akt signaling pathway. For the first time, we clarified the roles of CHPF in osteosarcoma, and our results suggested that CHPF might be a novel therapeutic target in the treatment strategies for osteosarcoma. | Yi Shen Jun Li Dan Peng Lele Liao Xia Chen Weiye Zhong Zicheng Liu Chao Yu Yuanliang Sun | 2023 | Genes & Diseases2023，10，5： | 0 |
| 16 | Study on Effect of Performance on Excess Sludge Disintegration by Ozone显示文摘In order to study the effect of excess sludge ozonation,a continuous experiment in lab scale process was carried out. During the treatment process,a high level of ozone was produced by the electrolysis-type ozone generator,and various parameters,such as Soluble Chemical Oxygen Demand ( SCOD) ,Mixed Liquor Suspended Solids ( MLSS) ,Mixed Liquor Volatile Suspended Solids ( MLVSS) ,pH and so on,which characterize sludge were investigated. A substantial reduction in the volume of sludge and the release of intracellular materials were observed: SCOD proliferated as a consequence of extending the ozone feeding time; MLSS and MLVSS,especially the ratio of MLVSS to MLSS,dwindled as the action time rose. Through analyzing the effluent quality and excess sludge activity,the sludge-water volume mixture ratio of 1∶ 20 with 50-60 minutes' oxidation treatment was found to be the optimal condition for ozonic disintegration of excess sludge. A remarkable sludge reduction rate of 57% could be achieved under the ozone feeding time of 40 minutes,which revealed the optimal action time. | Hui Jin Chuyin He Chunwei Bu Zicheng Wen Yun Li Lianpeng Sun | 2013 | Meteorological and Environmental Research2013，4，2： | 0 |
| 17 | Perceptual Quality Assessment for Point Clouds:A Survey显示文摘A point cloud is considered a promising 3D representation that has achieved wide applications in several fields.However,quality degradation inevitably occurs during its acquisition and generation,communication and transmission,and rendering and display.Therefore,how to accurately perceive the visual quality of point clouds is a meaningful topic.In this survey,we first introduce the point cloud to emphasize the importance of point cloud quality assessment(PCQA).A review of subjective PCQA is followed,including common point cloud distortions,subjective experimental setups and subjective databases.Then we review and compare objective PCQA methods in terms of modelbased and projection-based.Finally,we provide evaluation criteria for objective PCQA methods and compare the performances of various methods across multiple databases.This survey provides an overview of classical methods and recent advances in PCQA. | ZHOU Yingjie ZHANG Zicheng SUN Wei MIN Xiongkuo ZHAI Guangtao | 2023 | ZTE Communications2023，21，4： | 0 |
