| 1 | First ceratopsid dinosaur from China and its biogeographical implications显示文摘Ceratopsid dinosaurs represent one of the best known dinosaur groups in the Late Cretaceous, and their unquestionable fossil re-cords are exclusively restricted to western North America.Here we report a new ceratopsid dinosaur, Sinoceratops zhuchengensis gen.et sp.nov., from the Upper Cretaceous Wangshi Group of Zhucheng, Shandong Province, China.Cladistic analysis places this new taxon as the only known ceratopsid from outside North America, in a basal position within the Centrosaurinae.It is con-siderably larger than most other centrosaurines but similar in size to basal chasmosaurines.Furthermore, it is more similar to chasmosaurines than to other centrosaurines in several features, thus blurring the distinction of the two ceratopsid subgroups.This new find not only provides significant information on the morphological transition from non-ceratopsid to ceratopsid dinosaurs, but also complicates the biogeography of the Ceratopsidae, and further demonstrates that fossil sampling has profound effects on reconstructing dinosaurian biogeography. | XU Xing WANG KeBai ZHAO XiJin LI DunJing | 2010 | Chinese Science Bulletin2010，55，16： | 18 |
| 2 | TOPICS AND TRENDS OF THE ON-LINE PUBLIC CONCERNS BASED ON TIANYA FORUM显示文摘Many social events spread fast through the Intemet and arouse wide community discussions.Those on-line public opinions emerge into diverse topics along the time.Moreover,the strength of the topics is fluctuating.How to catch both primary topics and trend of topics over the shifting on-line discussions are not only of theoretical importance for scientific research,but also of practical importance for societal management especially in current China.To try the cutting-edge text analytic technologies to deal with unstructured on-line public opinions and provide support for social problem-solving in the big data era is worth an endeavour.This paper applies dynamic topic model(DTM)to explore the changing topics of new posts collected from Tianya Zatan Board of Tianya Club,the most influential Chinese BBS in China's Mainland.By analysis of the hot and cold terms trends,we catch the topics shift of main on-line concerns with illustrations of topics of school bus and environment in December of 2011.An algorithm is proposed to compute the strength fluctuation of each topic.With visualized analysis of the respective main topics in several months of 2012,some patterns of the topics fluctuation on the board are summarized. | Lina Cao Xijin Tang | 2014 | Journal of Systems Science and Systems Engineering2014，23，2： | 11 |
| 3 | Recent advances in the improvement of g-C_(3)N_(4) based photocatalytic materials显示文摘g-C_(3)N_(4) have been widely used in the fields of photocatalytic hydrogen production,photocatalytic degradation of dyes and oxidative degradation of toxic gases due to their excellent performance.It has attracted extensive attention in recent years due to its highly efficient photocatalytic capacity of hydrogen generation,water oxidation,carbon dioxide reduction and degradation of organic pollutants.Because of the abundant carbon and nitrogen composition of the earth,large-scale production and industrial applications of this material are possible.The modification of this material makes its performance more excellent so that this new material can obtain a steady stream of vitality.These outstanding works have become important materials and milestones on the road to mankind's photocatalytic hydrogen production.This review will begin with the basic idea of designing,synthesizing and improving g-C_(3)N_(4) based photocatalytic materials,and introduce the latest development of g-C_(3)N_(4) photocatalysts in hydrogen production from four aspects of controlling the carbon/nitrogen ratio,morphology,element doping and heterojunction structure of g-C_(3)N_(4) materials. | Yupeng Xing Xiaoke Wang Shuhua Hao Xueli Zhang Xiao Wang Wenxuan Ma Gang Zhao Xijin Xu | 2021 | Chinese Chemical Letters2021，32，1： | 10 |
| 4 | EXPLORING ON-LINE SOCIETAL RISK PERCEPTION FOR HARMONIOUS SOCIETY MEASUREMENT显示文摘The nearly 30-year economic growth miracle brings the consequent tremendous poor-rich gap leading strong drives for social transformation in current China.Chinese top leaders have realized to increase the peoples' income,improve quality of life and construct a 'harmonious society' as key missions especially in recent 10 years.How to measure a harmonious society is one important topic as different measures may lead to different development policies.This paper outlines over 10 indices relevant to measure a harmonious society.Some are global indicators,while some are contributed by domestic researchers and arouse debates.Most of those indicators require conducting surveys on social attitudes under micro levels,which is always time consuming with problem of data quality.As Internet technology advances provide ways to record and disseminate fresh community ideas and thoughts conveniently,detecting topics or emotions from on-line public opinions is becoming a trend or one supplement way to overcome those data acquisition problems.This paper discusses one approach to on-line societal risk perception using hot search words and BBS posts.Such a trial aims to provide another way to societal risk perception different from those in traditional socio psychology studies. Challenges are also indicated. | Xijin TANG | 2013 | Journal of Systems Science and Systems Engineering2013，22，4： | 9 |
| 5 | A New Ceratopsian from the Upper Jurassic Houcheng Formation of Hebei, China显示文摘A new ceratopsian taxon Xuanhuaceratops niei gen. et sp. nov. is erected based on four fragmentary specimens collected from the Late Jurassic Houcheng Formation, Hebei Province, China. Xuanhuaceratops shares a number of derived features with, and is closely related to, another probable Late Juarassic ceratopsian Chaoyangsaurus youngi, from which it differs in only possessing a single premaxillary tooth as well as in details of quadrate and scapular morphology. We hypothesize that these two taxa represent a primitive lineage of Ceratopsia that is basal to the psittacosaurid-neoceratopsian diversity, and propose the name Chaoyangsauridae for | ZHAO Xijin CHENG Zhengwu XU Xing Peter J.

| 6 | A New Titanosaurian Sauropod from Late Cretaceous of Nei Mongol, China显示文摘A specimen collected from the Upper Cretaceous Erlian Formation of Nei Mongol (Inner Mongolia), China, represents a new genus and species of titanosaurian sauropod. The new taxon is named and described on the basis of the holotype and the only known specimen, which comprises several dorsal, sacral, and caudal vertebrae, several dorsal ribs, one anterior chevron, and much of the pelvis. Diagnostic features of the new species include a thick ridge extending down from the postzygapophysis on the lateral surface of the neural arch of the posterior dorsal vertebrae, a transversely oriented accessory lamina present between the anterior centroparapophyseal limina and the lateral centraprezygapophyseal lamina of the posterior dorsal vertebrae, long, anteroventrally directed caudal rib that bears two distinctive fossae on its posterior margin on the anterior caudal vertebrae and a prominent vertical ridge above the pubic peduncle on the medial surface of the ilium, among others. The ilium is pneumatic, a feature not common among non-avian dinosaurs. The new taxon has an unusual combination of primitive and derived character states. Preliminary character analysis shows a complex character distribution within the Titanosauriformes. Recent titanosauriform discoveries suggest that a significant radiation occurred in Asia early in the titanosauriform evolution. | XU Xing ZHANG Xiaohong TAN Qingwei ZHAO Xijin TAN Lin | 2006 | Acta Geologica Sinica(English Edition)2006，80，1： | 7 |

| 8 | Constructing highly dispersed 0D Co3S4 quantum dots/2D g-C3N4 nanosheets nanocomposites for excellent photocatalytic performance显示文摘The development of noble-metal-free catalysts with high efficiency photocatalytic properties is critical to the heterogeneous catalysis. Herein, zero-dimensional(0 D) metal sulfide quantum dots/two-dimensional(2 D) g-C3N4 nanosheets(Co3S4/CNNS) nanocomposites are synthesized by a two-step method, including the ways of in-situ deposition and water bath. The highly dispersed Co3S4 quantum dots(particle size is2–4 nm) are evenly and tightly fixed on CNNS, which can be used as co-catalyst to effectively replace noble metals to improve the photocatalytic properties of CNNS. Co3S4/CNNS-900 has the apparent quantum efficiency, which is up to 7.85% at 400 nm. At the same time, the H2 evolution rate of Co3S4/CNNS-900 is 20,536.4 lmol gà1 hà1, which is 555 times than CNNS. The excellent photocatalytic performance is due to the highly dispersed Co3S4 quantum dots on 2 D CNNS, which facilitate the formation of more active sites, Co3S4/CNNS promotes the separation and migration of photogenerated carriers, shortens the migration distance of photogenerated carriers, and eventually leads to an increase of the photocatalytic performance. | Hongcen Yang Jiangmei Yin Ruya Cao Pengxiao Sun Shouwei Zhang Xijin Xu | 2019 | Science Bulletin2019，64，20： | 7 |

| 10 | Hierarchical CuCo_2O_4@nickel-cobalt hydroxides core/shell nanoarchitectures for high-performance hybrid supercapacitors显示文摘Ni_(0.5)Co_(0.5)(OH)_2 nanosheets coated CuCo_2O_4 nanoneedles arrays were successfully designed and synthesized on carbon fabric. The core/shell nanoarchitectures directly served as the binder-free electrode with a superior capacity of 295.6 mAh g^(-1) at 1 Ag^(-1), which still maintained 220 mAh g^(-1) even at the high current density of 40 Ag^(-1), manifesting their enormous potential in hybrid supercapacitor devices. The asassembled CuCo_2O_4@Ni_(0.5)Co_(0.5)(OH)_2//AC hybrid supercapacitor device exhibited favorable properties with the specific capacitance as high as 90 Fg^(-1) at 1 Ag^(-1) and the high energy density of 32 Wh kg^(-1) at the power density of 800 Wkg^(-1). Furthermore, the as-assembled device also delivered excellent cycling performance(retaining 91.9% of the initial capacitance after 12,000 cycles at 8 Ag^(-1)) and robust mechanical stability and flexibility, implying the huge potential of present hierarchical electrodes in energy storage devices. | Chenggang Wang Kai Guo Weidong He Xiaolong Deng Peiyu Hou Fuwei Zhuge Xijin Xu Tianyou Zhai | 2017 | Science Bulletin2017，62，16： | 6 |
| 11 | Synthesis of Z-scheme g-C3N4 nanosheets/Ag3PO4 photocatalysts with enhanced visible-light photocatalytic performance for the degradation of tetracycline and dye显示文摘Graphene-like C3N4/Ag3PO4 photocatalysts are synthesized by calcination and solutions precipitating method.The obtained g-C3N4/Ag3PO4 composites display excellent photocatalytic activity for the degradation of methylene orange(MO),rhodamine B(RhB)and tetracycline(TC)under visible light irradiation.The solutions containing RhB(10 mg/L)and MO(10 mg/L)can be efficiently degraded within15 min and 30 min.Especially,nearly 80%of TC(50 mg/L)is degraded within 20 min.which are much better than those of pure g-C3N4 nanosheets and Ag3PO4,implying that strong interaction and reasonable energy band alignment in the contact interface can effectively transfer the carries.Furthermore,the g-C3N4/Ag3PO4 composites exhibit the improved stability,and only a slight decrease is observed after three recycling runs.Moreover,the impact of inorganic ions and PH values on the degradation performance is rather small.The Z-scheme photocatalytic mechanism of the g-C3N4/Ag3PO4 composites based on the active species trapping experimental is proposed.This work demonstrates the promising applications of the g-C3N4/Ag3PO4 composites in environmental issues. | Meng Ding Juanjuan Zhou Hongcen Yang Ruya Cao Shouwei Zhang Minghui Shao Xijin Xu | 2020 | Chinese Chemical Letters2020，31，1： | 6 |

| 13 | SOME DEVELOPMENTS IN THE STUDIES OF META-SYNTHESIS SYSTEM APPROACH显示文摘In the early 1990s, Professor Qian Xuesen (Tsien HsueShen) and his colleagues proposed the Metasynthesis system approach for solving the open complex giant system problems. The method emphasizes the synthesis of collected information and knowledge of various kinds of experts, and combining quantitative methods with qualitative knowledge. Later it is evolved into Hall of Workshop for Meta-Synthetic Engineering (HWMSE) which emphasizes to make use of breaking advances in information technologies. Then continuous endeavors have been taken to put those ideas into practice. With tremendous advances in networking and distributed computing technologies, past difficulties in implementation are disappearing together with further understandings of HWMSE and fruitful results achieved in similar or relevant research fields in recent years in China. In this paper some of those development are introduced, together with some parallel research work abroad. | JifaGU Xijin TANGInstitute of Systems Science, Academy of Mathematics and System Sciences Chinese Academy of Sciences, Beijing 100080 P.

| 14 | Study on Energy Conversion Characteristics in Volute of Pump as Turbine显示文摘A volute is a curved funnel with cross-sectional area increasing towards the discharge port.The volute of a centrifugal pump is the casing hosting the fluid being pumped by the impeller.In Pump-as-turbine devices(PAT),vice versa the volute plays the role of energy conversion element.In the present analysis,this process is analyzed using CFD.The results show that in the contraction section of volute the conversion between dynamic pressure energy and static pressure energy essentially depends on the reduction of flow area,while in the spiral section,frictional losses also play a significant role.From the throat to the end of the volute,the flow decreases in a wave-like manner. | Senchun Miao Hongbiao Zhang Fengxia Shi Xiaohui Wang Xijin Ma | 2021 | Fluid Dynamics & Materials Processing2021，17，1： | 5 |
| 15 | Enhanced photocatalytic activity of quantum-dot-sensitized one-dimensionally-ordered ZnO nanorod photocatalyst显示文摘An efcient photocatalyst was fabricated by assembling quantum dots(QDs) onto one-dimensionally-ordered ZnO nanorods, and the photocatalytic properties for Methyl Orange degradation were investigated by scanning electron microscopy, transmission electron microscopy, X-ray difraction, UV-Vis-NIR absorption spectroscopy and photoluminescence. The results indicate that the catalyst with assembled QDs is more favorable for the degradation than the pristine ZnO nanorods. The QDs with core-shell structure lower the photocatalytic ability due to the higher carrier transport barrier of the ZnS shell layer. Besides its degradation efciency, the photocatalyst has several advantages given that the one-dimensionally-ordered ZnO nanorods have been grown directly on indium tin oxide substrates. The article provides a new method to design an efective and easily recyclable photocatalyst. | Jinzhao Huang Song Liu Lei Kuang Yongdan Zhao Tao Jiang Shiyou Liu Xijin Xu | 2013 | Journal of Environmental Sciences2013，25，12： | 5 |
| 16 | Aquaporin 5 is degraded by autophagy in diabetic submandibular gland显示文摘Autophagy is a catabolic process which is involved in the development of many diseases including diabetes mellitus and its complications. Hyposalivation is a common complication of diabetes mellitus, whereas its mechanism remains unclear. Here, we observed that the stimulated salivary flow rate of SMG was significantly decreased in db/db mice, a diabetic mice model. The expressions of aquaporin 5(AQP5), a water channel protein, were decreased, whereas the m RNA level of AQP5 was increased in SMGs of both diabetic patients and mice. Under transmission electron microcope, more autophagosomes were detected in diabetic SMGs. Expressions of autophagy related proteins LC3 II, Beclin-1 and ATG5 were increased, meanwhile autophagy substrate p62 was decreased in SMGs of diabetic patients and mice, indicating that autophagy was activated in diabetic SMG.Double immunofluorescence staining showed that the colocalization of AQP5 and LC3 was increased in SMGs of diabetic mice.In cultured SMG-C6 cells, high glucose(HG), but not high osmotic pressure, reduced AQP5 protein expression and induced autophagy. Moreover, inhibition of autophagy by 3-methyladenin, an autophagy inhibitor, or by autophagy-related gene 5 siRNA, decreased HG-induced AQP5 reduction in SMG-C6 cells. Additionally, the expression of p-p85, p-Akt and p-mTOR were decreased in HG-treated SMG-C6 cells. Pretreatment with 740 Y-P, a PI3 K agonist, significantly suppressed HG-induced autophagy and AQP5 degradation. Taken together, these results indicate that autophagy plays a crucial role in AQP5 degradation in diabetic SMG via PI3 K/Akt/mTOR signaling pathway, which contributes to the dysfunction of diabetic SMG. Our study provides a novel mechanism of diabetic hyposalivation. | Yan Huang Xijin Shi Qianying Mao Yan Zhang Xin Cong Xueming Zhang Zhejing Zhang Liling Wu Ruolan Xiang Guangyan Yu | 2018 | Science China(Life Sciences)2018，61，9： | 5 |
| 17 | ZIF-67 derived hollow Ni-Co-Se nano-polyhedrons for flexible hybrid supercapacitors with remarkable electrochemical performances显示文摘Nano-polyhedral NiSe2/CoSe2(Ni-Co-Se) with hollow architectures are synthesized by selenizing the precursors of Ni-Co bimetallic hydroxides that are directly derived from ZIF-67.The as-fabricated Ni-Co-Se electrodes exhibit high specific capacitance of 1668 F/g at 1 A/g accompanying with outstanding rate capability(about 82.8% retention of the initial capacity at 20 A/g).The corresponding Ni-Co-Se//AC all-solid-state hybrid supercapacitors are assembled by directly using the Ni-Co-Se on carbon fabric as the positive electrode,which deliver high energy density and power density(38.5 Wh/kg at 802.1 W/kg,32.0 Wh/kg at 8008.8 W/kg),excellent cyclic stability(82.3% retention after 5000 cycle) and robust mechanical flexibility(no obvious attenuation at bending to different angles).This work will provide a new and smart route for constructing transition metal selenides for supercapacitor devices. | Guangmeng Qu Xixi Zhang Guotao Xiang Yunrui Wei Jiangmei Yin Zonghua Wang Xiaoli Zhang Xijin Xu | 2020 | Chinese Chemical Letters2020，31，7： | 3 |
