| 1 | The crustal structures of the central Longmenshan along and its margins as related to the seismotectonics of the 2008 Wenchuan Earthquake显示文摘In 2010,a 500-km-long wide-angle reflection/refraction seismic profile was completed,running northwest from the central Sichuan Basin.This profile orthogonally crosses the meizoseismal area of great Wenchuan earthquake of 12 May 2008,which occurred in the central part of the Longmenshan.The profile also passes through the northwestern Sichuan Plateau,along which a new deep seismic sounding observation system was set up that was much improved over previous datasets and enabled abundant observations to be recorded.Seismic wave phase records that reflect the structural characteristics of different tectonic blocks,especially the complicated phase features associated with the Wenchuan earthquake,were calculated and analyzed in detail.A 2D crustal P-wave velocity model for the orogenic belt in the central Longmenshan and its margins was determined,and crustal structure differences between the stable Sichuan Basin and the thickened northwestern Sichuan Plateau were characterized.Lithological variations within the upper and lower crust in the interior of the plateau,especially a great velocity decrease and plastic rheological properties associated with strong lithologic weakening in lower crust,were detected.From west to east in the lower crust beneath the orogenic belt lying between the Sichuan Basin and the northwestern Sichuan Plateau,a giant shovel-like upwelling is observed that dips gently in the lower part and at higher angles in the upper part;this is inferred to be related to the fault systems in the central Longmenshan.An upwelling in the upper-middle crust along the eastern margin of the orogenic belt is associated with steeply dipping thrusts that strongly uplift the upper crust and crystalline basement beneath a central fault system in the Longmenshan.The data,combined with an understanding of the regional tectonic stress field and previous geological results,enable a discussion of basin-and-range coupling,orogenic tectonics,the crustal fault system,and the seismogenic tectonic environment of the central Longmenshan along the eastern margin of the Qinghai-Tibet Plateau. | JIA ShiXu LIU BaoJin XU ZhaoFan LIU Zhi FENG ShaoYing ZHANG JianShi LIN JieYan TIAN XiaoFeng LIU QiaoXia GUO WenBin | 2014 | Science China Earth Sciences2014，57，4： | 26 |

| 3 | Lithospheric structure and faulting characteristics of the Helan Mountains and Yinchuan Basin: Results of deep seismic reflection profiling显示文摘The Helan Mountains and Yinchuan Basin(HM-YB) are located at the northern end of the North-South tectonic belt,and form an intraplate tectonic deformation zone in the western margin of the North China Craton(NCC).The HM-YB has a complicated history of formation and evolution,and is tectonically active at the present day.It has played a dominant role in the complex geological structure and modern earthquake activities of the region.A 135-km-long deep seismic reflection profile across the HM-YB was acquired in early 2014,which provides detailed information of the lithospheric structure and faulting characteristics from near-surface to various depths in the region.The results show that the Moho gradually deepens from east to west in the depth range of 40-48 km along the profile.Significant differences are present in the crustal structure of different tectonic units,including in the distribution of seismic velocities,depths of intra-crustal discontinuities and undulation pattern of the Moho.The deep seismic reflection profile further reveals distinct structural characteristics on the opposite sides of the Helan Mountains.To the east,The Yellow River fault,the eastern piedmont fault of the Helan Mountains,as well as multiple buried faults within the Yinchuan Basin are all normal faults and still active since the Quaternary.These faults have controlled the Cenozoic sedimentation of the basin,and display a 'negative-flower' structure in the profile.To the west,the Bayanhaote fault and the western piedmont fault of the Helan Mountains are east-dipping thrust faults,which caused folding,thrusting,and structural deformation in the Mesozoic stratum of the Helan Mountains uplift zone.A deep-penetrating fault is identified in the western side of the Yinchuan Basin.It has a steep inclination cutting through the middle-lower crust and the Moho,and may be connected to the two groups of faults in the upper crust.This set of deep and shallow fault system consists of both strike-slip,thrust,and normal faults formed over different eras,and provides the key tectonic conditions for the basin-mountains coupling,crustal deformation and crust-mantle interactions in the region.The other important phenomenon revealed from the results of deep seismic reflection profiling is the presence of a strong upper mantle reflection(UMR) at a depth of 82-92 km beneath the HM-YB,indicating the existence of a rapid velocity variation or a velocity discontinuity in that depth range.This is possibly a sign of vertical structural inhomogeneity in the upper mantle of the region.The seismic results presented here provide new clues and observational bases for further study of the deep structure,structural differences among various blocks and the tectonic relationship between deep and shallow processes in the western NCC. | LIU BaoJin FENG ShaoYing JI JiFa WANG ShuaiJun ZHANG JianShi YUAN HongKe YANG GuoJun | 2017 | Science China Earth Sciences2017，60，3： | 11 |

| 6 | Phylogenetic Analyses Reveal a Unique Species of Elaphe(Serpentes,Colubridae)New to Science显示文摘The snakes comprising the monophyletic group referred to as ratsnakes are found throughout Asia,Europe and the New World.Recently,three snake samples likely belonging to the ratsnakes were collected in Zoige County,Sichuan Province,China.Species identity was difficult to delimit morphologically because the specimens were juveniles and partially damaged.Subsequently,a molecular phylogenetic approach was used.Portions of three mitochondrial genes(cyt b,ND4 and 12S rRNA) were sequenced and analyzed.The results showed that they were sister to the genus Elaphe.Very little genetic variation was found among the three samples.The minimum genetic distances between these samples and those within Elaphe were greater than any currently recognized species within the genus.We conclude that this likely represents a new species within the genus Elaphe.Adult specimens and a morphologic description are needed for further study. | LING Chen LIU Shaoying HUANG Song Frank T.Burbrink GUO Peng SUN Zhiyu ZHAO Jie | 2010 | Asian Herpetological Research2010，1，2： | 4 |
| 7 | Test Case Generation from Conjunctions of Predicates with Model Checking显示文摘Automatic test case generation from a prepost style formal specification must deal with the issue of how to generate test cases from a conjunction of atomic predicate expressions, but unfortunately this problem has not been effectively solved due to its intrinsic difficulty. We describe a practical approach to tackling this problem by utilizing the model checking technique. An algorithm that converts test case generation from a conjunction of atomic predicate expressions into model checking is proposed. We discuss how the algorithm deals with atomic predicate expressions involving only variables of numeric types, and extend the discussion to variables of compound types such as set, sequence, and composite types. Case studies are presented to assess the feasibility and effectiveness of our approach. | TIAN Cong LIU Shaoying DUAN Zhenhua | 2014 | Chinese Journal of Electronics2014，23，2： | 4 |
| 8 | Compressed sensing digital receiver and orthogonal reconstructing algorithm for wideband ISAR radar显示文摘This paper proposes a novel design of intermediate frequency(IF) digital receiver for wideband inverse synthetic aperture radar(ISAR) based on compressed sensing(CS). For the convenience in engineering application, we use random sampling in the digital receiver and make it possible to digitize the wideband IF signal using a commercial off-the-shelf analog-to-digital converter with sub-Nyquist sample rate. Besides, a novel basis for the sparse representation of real-valued ISAR radar echoes is built in this paper, and an orthogonal CS reconstructing algorithm is proposed based on this. Using our proposed method, the complex-valued range profile of target can be directly reconstructed from the subsampled real raw echo. The phase information of target range profile, which is very important for the coherent processing in ISAR imaging, is well reserved during the reconstruction. As a result, the down converter and matched filter, which are essential in conventional radar receiver, can be eliminated in our CS digital receiver. A series of simulation validates our design and demonstrates the feasibility of the sub-Nyquist sampling. The simulation results of ISAR imaging verify the validity and superiority of the proposed orthogonal reconstructing method. | HOU QingKai LIU Yang FAN LiJie SU ShaoYing | 2015 | Science China(Information Sciences)2015，58，2： | 4 |
| 9 | GPU-CA model for large-scale land-use change simulation显示文摘Land-use change simulation for large-scale regions(i.e.provincial regions or countries) is very useful for many global studies.Such simulation,however,is affected by computational capability of general computers.This paper proposes a method to implement cellular automata(CA) for land use change simulation based on graphics processing units(GPUs).This method can be applied to large-scale land-use change simulations by combining the latest GPU high-performance computing technology and CA.We carried out the experiments by simulating land-use change processes at a provincial scale.This involves a lot of sophisticated techniques,such as model mapping,and computational procedure of GPU-CA model.This proposed model has been validated by land-use change simulation in Guangdong Province,China.The comparison indicates that the GPU-CA model is faster than traditional CA by 30 times.Such improvement is crucial for land-use change simulations in provincial regions and countries.The outputs of the simulation can be further used to provide information to other global change models. | LI Dan LI Xia LIU XiaoPing CHEN YiMin LI ShaoYing LIU Kai QIAO JiGang ZHENG YiZhong ZHANG YiHan LAO ChunHua | 2012 | Chinese Science Bulletin2012，57，19： | 4 |
| 10 | Energy Optimization of the Fin/Rudder Roll Stabilization System Based on the Multi-objective Genetic Algorithm (MOGA)显示文摘精力优化是为在最后十年的轮船转动减小系统的关键问题之一。根据轮船运动的非线性的特征,自由的四度鳍 / 赤睛鱼转动稳定的非线性的模型能被建立。这份报纸分析克服抵抗和 yaw 引起的精力消费,它作为新性能索引被加到鳍 / 赤睛鱼转动稳定系统。以便达到转动减小,轮船路线保留和精力优化的目的,自我调节的 PID 控制器基于多客观的基因算法(MOGA ) ,方法被用来优化性能索引。另外,随机的重量系数被采用造一个多客观的基因算法优化模型。客观功能被改进以便客观功能能被规范化为经常的水平。模拟结果证明控制方法基于 MOGA,与传统的控制方法相比,不是仅仅改进效率卷稳定并且偏航控制精确,而且优化系统的精力。建议方法论能以不同的海状态得到更好的表演。 | Lijun Yu Shaoying Liu Fanming Liu Hui Wang | 2015 | Journal of Marine Science and Application2015，14，2： | 3 |
| 11 | Projected total energy surface description for axial shape asymmetry in ^(172)W显示文摘The projected total energy surface(PTES)approach has been developed based on the triaxial projected shell model(TPSM)hybridized with the macroscopic–microscopic method.The total energy of an atomic nucleus is decomposed into macroscopic,microscopic and rotational terms.The macroscopic and microscopic components are described with the liquid drop model and Strutinsky method,respectively,and the rotational energy is given by the TPSM,the term beyond the mean field.To test theory,the PTES calculations have been carried out for the yrast states of the well deformed rare earth nucleus172W,and the theoretical results are in good agreement with the experimental data.By using the equilibrium quardrupole deformations(ε2andγ)determined by the PTES,the calculation of the transition quardrupole moment(Qt)in function of spin also reproduces the experimental data.A comparison between the PTES and TRS methods has been made for theoretical and application uses. | TU Ya CHEN YongShou GAO ZaoChun YU ShaoYing LIU Ling | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，11： | 3 |
| 12 | Modeling and verifying chlorine decay and chloroacetic acid formation in drinking water chlorination显示文摘This study presents a phenomenological model that can be used by the water professionals to quantify chlorine decay and disinfection byproduct(DBP)formation in water.The kinetic model was developed by introducing the concept of limiting chlorine demand and extending an established reactive species approach.The limiting chlorine demand,which quantifies chlorine reactive natural organic matter(NOM)on an equivalent basis,was mathematically defined by the relation between ultimate chlorine residue and initial chlorine dose.It was found experimentally that NOM in water has limiting chlorine demand that increases with chlorine dose once the ultimate residue is established.These results indicated that the complex NOM has a unique ability to adjust chemically to the change in redox condition caused by the free chlorine.It is attributed mainly to the redundant functional groups that persist in heterogeneous NOM molecules.The results also demonstrated that the effect of chlorine dose on the rate of chlorine decay can be quantitatively interpreted with the limiting chlorine demand.The kinetic model developed was validated for chlorine decay and chloroacetic acid formation in finished drinking water. | Wenjun LIU Shaoying QI | 2010 | Frontiers of Environmental Science & Engineering2010，4，1： | 3 |
| 13 | Synthesis of Poly(isosorbide carbonate) via Melt Polycondensation Catalyzed by a KF/MgO Catalyst显示文摘MgO loaded with KF was prepared by using tlie impregnation method and was employed as the catalyst for tlie direct traiisesterification of diphenyl carbonate(DPC) witli isosorbide to synthesize high-molecular-weight poly(isosorbide carbonate)(PIC). The relationship between physical-chemical properties and catalytic performance for KF/MgO in this melt process was investigated by various characterization techniques. The basic site amount and strength were found to be responsible for this transesterification process, and the medium and strong basic sites tended to promote the polycondensation reaction. 20-KF/Mg0-500 exhibited the best catalytic performance, giving PIC with Mw of 84200 and glass transition temperature(rg) of 173℃ under optimal conditions. Additionally, 20-KF/MgO-500 was found to catalyze the transerification of DPC with isosorbide and other diols to syntliesize the corresponding poly(aliphatic diol-co-isosorbide carbonate)s(PAICs). This excellent activity can be ascribed to the presence of an abundance of basic sites and their specific basic strength on the surface of KF/MgO. | SHEN Xiaolong LIU Shaoying WANG Qingyin ZHANG Hua WANG Gongying | 2019 | Chemical Research in Chinese Universities2019，35，4： | 3 |
| 14 | Synthesis and Properties of Poly(butylene carbonate-co-spirocyclic carbonate)显示文摘Poly(butylene carbonateXPBC) has significantly promising applications as a degradable material in the field of polymers, while its poor thermal performance and low crystallization rate are its main defects. To overcome these shortcomings, a series of poly(butylene carbonate-co-spirocyclic carbonateXPBSC) copolymers were synthesized from diphenyl carbonate, 1,4-butanediol and spiroglycol via two-step polycondensation reactions, using magnesium oxide as a catalyst. Differential scanning calorimetry(DSC) results indicated that the glass transition temperature(Tg) values of PBSC copolymers were enhanced from -19℃ to 56℃ with rising the spiroacetal moiety content. Thermogravimetric analysis(TGA) results showed that the resulting PBSCs have a higher thermal stability than that of poly(butylene carbonate). Wide angle X-ray diflraction(WXRD) patterns were characterized to investigate the crystallization behaviour of PBSCs. Tensile testing demonstrated that copolymerization of spiroacetal moieties into PBC chains imparted PBSC with favourable mechanical performance. Typically, PBSC 30 had a tensile modulus of (1735±430) MPa, a tensile strength of (42±5) MPa and an elongation of 504%±36%. | ZHU Changliang LIU Shaoying WANG Qingyin ZHANG Hua | 2019 | Chemical Research in Chinese Universities2019，35，4： | 3 |
| 15 | Derivation and characterization of human embryonic stem cell lines from poor quality embryos显示文摘Poor quality embryos discarded from in vitro fertilization (IVF) laboratories are good sources for deriving human embryonic stem cell (hESC) lines. In this study, 166 poor quality embryos donated from IVF centers on day 3 were cultured in a blastocyst medium for 2 days, and 32 early blastocysts were further cultured in a blastocyst optimum culture medium for additional 2 days so that the inner cell masses (ICMs) could be identified and isolated easily. The ICMs of 17 blastocysts were isolated by a mechanical method, while those of the other 15 blastocysts were isolated by immunosurgery. All isolated ICMs were inoculated onto a feeder layer for subcultivation. The rates of ICM at- tachment, primary ICM colony formation and the efficiency of hESC derivation were similar between the ICMs isolated by the two methods (P>0.05). As a result, four new hESC lines were established. Three cell lines had normal karyotypes and one had an unbalanced Robertsonian translocation. All cell lines showed normal hESC characteristics and had the differentiation ability. In conclusion, we established a stable and effective method for hESC isolation and culture, and it was confirmed that the mechanical isolation was an effective method to isolate ICMs from poor embryos. These results further indicate that hESC lines can be derived from poor quality embryos discarded by IVF laboratories. | Weiqiang Liu, Yifei Yin, Xiaolin Long, Yumei Luo, Yonghua Jiang, Wenhong Zhang, Hongzi Du, Shaoying Li, Yuhong Zheng, Qing Li, Xinjie Chen, Baoping Liao, Guohong Xiao, Weihua Wang, Xiaofang Sun Guangzhou Key Laboratory of Reproductive and Genetics Institute of Gynecology and Obstetrics, The Third Affiliated Hospital of Guangzhou Medical College, Guangzhou 510150, China | 2009 | Journal of Genetics and Genomics2009，36，4： | 3 |

| 17 | Coupled carbon and sulfur isotope behaviors and other geochemical perspectives into marine methane seepage显示文摘Methane seepage is the signal of the deep hydrocarbon reservoir. The determination of seepage is significant to the exploration of petroleum, gas and gas hydrate. The seepage habits microbial and macrofaunal life which is fueled by the hydrocarbons, the metabolic byproducts facilitate the precipitation of authigenic minerals. The study of methane seepage is also important to understand the oceanographic condition and local ecosystem. The seepage could be active or quiescent at different times. The geophysical surveys and the geochemical determinations reveal the existence of seepage. Among these methods, only geochemical determination could expose message of the dormant seepages. The active seepage demonstrates high porewater methane concentration with rapid SO_4^(2–) depleted, low H_2S and dissolved inorganic carbon(DIC), higher rates of sulfate reduction(SR) and anaerobic oxidation of methane(AOM). The quiescent seepage typically develops authigenic carbonates with specific biomarkers, with extremely depleted ~13C in gas, DIC and carbonates and with enriched ~34S sulfate and depleted ~34S pyrite. The origin of methane, minerals precipitation, the scenario of seepage and the possible method of immigration could be determined by the integration of solutes concentration, mineral composition and isotopic fractionation of carbon, sulfur. Numerical models with the integrated results provide useful insight into the nature and intensity of methane seepage occurring in the sediment and paleooceanographic conditions. Unfortunately, the intensive investigation of a specific area with dormant seep is still limit. Most seepage and modeling studies are site-specific and little attempt has been made to extrapolate the results to larger scales. Further research is thus needed to foster our understanding of the methane seepage. | LIU Lihua FU Shaoying ZHANG Mei GUAN Hongxiang WU Nengyou | 2017 | Acta Oceanologica Sinica2017，36，6： | 2 |
| 18 | SLC1A1-mediated cellular and mitochondrial influx of R-2-hydroxyglutarate in vascular endothelial cells promotes tumor angiogenesis in IDH1-mutant solid tumors显示文摘Muta nt isocitrate dehydrog en ase 1(mlDH1)drives tumorigenesis via produci ng on cometabolite R-2-hydroxyglutarate(R-2-HG)across various tumor types.However,mlDHl in hibitors appear only effective in hematological tumors.The therapeutic ben efit in solid tumors remains elusive,likely due to the complex tumor microenvironment.In this study,we discover that R-2-HG produced by IDH1-mutant tumor cells is preferentially imported into vascular endothelial cells and remodels mitochondrial respiration to promote tumor angiogenesis,conferring a therapeutic vulnerability in IDH1-mutant solid tumors.Mechanistically,SLC1 Alz a Na'-depe ndent glutamate tran sporter that is prefere ntially expressed in en dothelial cells,facilitates the in flux of R-2-HG from the tumor microenvironment into the endothelial cells as well as the intracellular trafficking of R-2-HG from cytoplasm to mitochondria.R-2-HG hijacks SLC1A1 to promote mitochondrial Na^(+)/Ca^(2+)exchange,which activates the mitochondrial respiratory chain and fuels vascular en dothelial cell migratio n in tumor an giogenesis.SLC1A1 deficiency in mice abolishes mlDHl-promoted tumor an giogenesis as well as the therapeutic benefit of mlDHl in hibitor in solid tumors.Moreover,we report that HH2301,a newly discovered mlDHl inhibitor,shows promising efficacy in treating IDH1-mutant cholangiocarcinoma in preclinical models.Together,we identify a new role of SLC1A1 as a gatekeeper of R-2-HG-mediated crosstalk between IDH1-mutant tumor cells and vascular en dothelial cells,and dem on strate the therapeutic potential of mlDHl in hibitors in treating IDH1-muta nt solid tumors via disrupting R-2-HG-promoted tumor angiogenesis. | Xiaomin Wang Ziqi Chen Jun Xu Shuai Tang Nan An Lei Jiang Yixiang Zhang Shaoying Zhang Qingli Zhang Yanyan Shen Shijie Chen Xiaojing Lan Ting Wang Linhui Zhai Siyuwei Cao Siqi Guo Yingluo Liu Aiwei Bi Yuehong Chen Xiameng Gai Yichen Duan Ying Zheng Yixian Fu Yize Li Liang Yuan Linjiang Tong Kun Mo Mingcheng Wang Shu-Hai Lin Minjia Tan Cheng Luo Yi Chen Jia Liu Qiansen Zhang Leping Li Min Huang | 2022 | Cell Research2022，32，7： | 2 |

| 20 | Comprehensive Multi-Level Exploration of Buried Active Faults:an Example of the Yinchuan Buried Active Fault显示文摘The paper introduces the steps and methods of multi-approach,multi-level exploration of buried faults in thick Quaternary sediment regions by taking the test exploration of the Yinchuan active fault as example.Based on the comprehensive analyses of previous data,we choose the Xinqushao Village of Xingqing District of Yinchuan City as the test site for the comprehensive exploration.Firstly,we adopted shallow seismic investigation with group intervals of 10m,5m and 1m to gradually trace layer by layer the master fault of the Yinchuan buried fault from a deep depth to a shallow depth where drilling could be used.Then,with composite geological profile drilling,we determined the precise location and dip angle of the fault.The drilling show the buried depth of the upper offset point is 8.3m.Finally,large-scale trenching revealed that the actual buried depth of the upper offset point of the fault is 1.5m from the ground surface and there are paleoearthquake events of 5 stages.Combined with the preliminary result of corresponding sample age,we conclude the Yinchuan buried fault is a mid to late Holocene active fault. | Chai Chizhang Meng Guangkui Du Peng Wang Yin Liu Baojin Shen Weihua LeiQiyun Liao Yuhua Zhao Chengbin Feng Shaoying Zhang Xuehui Xie Xiaofeng | 2007 | Earthquake Research in China2007，21，3： | 1 |
