| 1 | Source mechanism of strong aftershocks (M_s≥5.6) of the 2008/05/12 Wenchuan earthquake and the implication for seismotectonics显示文摘Dozens of >M5, hundreds of >M4, and much more >M3 aftershocks occurred after the 2008/05/12 Wenchuan earthquake, which were well recorded by permanent and portable seismic stations. After relocated with P arrival, the >M3 aftershocks show two trends of distribution, with most of the aftershocks located along the north-east strike consistent with Longmenshan fault system, yet there is a north-west trend around the epicenter. It seems that substantially more aftershocks occur in regions with crystalline bedrocks. Then we collected waveform data from National Digital Seismograph Network and regional seismograph network of China, and employed 'Cut and Paste' method to obtain focal mechanisms and depths of the big aftershocks (M≥5.6). While most of those aftershocks show thrust mechanism, there are some strike slip earthquakes in the northern-most end of the rupture. Focal mechanisms show that the events located on the southern part of central Beichuan-Yingxiu Fault (BY) are mainly thrust earthquakes, which is consistent with initial mechanism of the main shock rupture. In the north part the aftershocks along the BY are also dominated by thrust slip, which is quite different from the right slip rupture of the main shock. Around Qingchuan-Pingwu Fault, the focal mechanisms are dominated by right-slip rupture with large depths (~18 km). So we suspected that in the north part the main shock might rupture on two faults: Beichuan Fault and Qingchuan-Pingwu Fault. The complex pattern of aftershock mechanisms argues for presence of a complicated fault system in the Longmenshan area. | ZHENG Yong1,2,MA HongSheng3,Lü Jian4,NI SiDao5,LI YingChun6 & WEI ShengJi2 1 Institute of Geodesy and Geophysics,Chinese Academy of Sciences,Wuhan 430077,China 2 Institute of Geophysics,Chinese Earthquake Administration,Beijing 100086,China 3 Institute of Earthquake Science,Chinese Earthquake Administration,Beijing 100086,China 4 Earthquake Administration of Jiangxi Province,Nanchang 330039,China 5 School of Earth and Space Science,University of Science and Technology of China,Hefei 230026,China 6 Earthquake Administration of Jiangsu Province,Nanjing 210014,China | 2009 | Science China Earth Sciences2009，52，6： | 100 |

| 7 | Influence of High Temperature Stress on Net Photosynthesis, Dry Matter Partitioning and Rice Grain Yield at Flowering and Grain Filling Stages显示文摘Climate change is recognized to increase the frequency and severity of extreme temperature events. At flowering and grain filling stages, risk of high temperature stress (HTS) on rice might increase, and lead to declining grain yields. A regulated cabinet experiment was carried out to investigate effects of high temperature stress on rice growth at flowering and grain-filling stages. Results showed that no obvious decrease pattern in net photosynthesis appeared along with the temperature rising, but the dry matter allocation in leaf, leaf sheath, culm, and panicle all changed. Dry weight of panicle decreased, and ratio of straw to total above ground crop dry weight increased 6-34% from CK, which might have great effects on carbon cycling and green house gas emission. Grain yield decreased significantly across all treatments on average from 15 to 73%. Occurrence of HTS at flowering stage showed more serious influence on grain yield than at grain filling stage. High temperature stress showed negative effects on harvest index. It might be helpful to provide valuable information for crop simulation models to capture the effects of high temperature stress on rice, and evaluate the high temperature risk. | L Guo-hua WU Yong-feng BAI Wen-bo MA Bao WANG Chun-yan SONG Ji-qing | 2013 | Journal of Integrative Agriculture2013，12，4： | 19 |

| 9 | On environment-driven software model for Internetware显示文摘Internetware is envisioned as a general software paradigm for the application style of resources integration and sharing in the open, dynamic and uncertain platforms such as the Internet. Continuing the agent-based Internetware model presented in a previous paper, in this paper, after an analysis of the behavioral patterns and the technical challenges of environment-driven applications, a software-structuring model is proposed for environment-driven Internetware applications. A series of explorations on the enabling techniques for the model, especially the modeling, management and utilization of context information are presented. Several prototypical systems have also been built to prove the concepts and evaluate the techniques. These research efforts make a further step toward the Internetware paradigm by providing an initial framework for the construction of context-aware and self-adaptive software application systems in the open network environment. | Lǔ Jian MA XiaoXing TAO XianPing CAO Chun HUANG Yu YU Ping | 2008 | Science in China(Series F)2008，51，6： | 17 |

| 11 | miR-182参与调节胶质母细胞瘤的凋亡、生长和分化(英文)显示文摘Glioblastoma multiforme(GBM)is a lethal,therapy-resistant brain cancer consisting of numerous tumor cell subpopulations,including stem-like glioma-initiating cells(GICs),which contribute to tumor recurrence following initial response to therapy.Here,we identified miR-182 as a regulator of apoptosis,growth,and differentiation programs whose expression level is correlated with GBM patient survival.Repression of Bcl2-like12(Bcl2L12),c-Met,and hypoxia-inducible factor 2α(HIF2A)is of central importance to miR-182 anti-tumor activity,as it results in enhanced therapy susceptibility,decreased GIC sphere size,expansion,and stemness in vitro.To evaluate the tumor-suppressive function of miR-182 in vivo,we synthesized miR-182-based spherical nucleic acids(182-SNAs);i.e.,gold nanoparticles covalently functionalized with mature miR-182 duplexes.Intravenously administered 182-SNAs penetrated the bloodbrain/blood-tumor barriers(BBB/BTB)in orthotopic GBM xenografts and selectively disseminated throughout extravascular glioma parenchyma,causing reduced tumor burden and increased animal survival.Our results indicate that harnessing the anti-tumor activities of miR-182 via safe and robust delivery of 182-SNAs represents a novel strategy for therapeutic intervention in GBM. | Kouri FM Hurley LA Daniel WL Day ES Hua Y Hao L Peng CY Merkel TJ Queisser MA Ritner C Zhang H James CD Sznajder JI Chin L Giljohann DA Kessler JA Peter ME Mirkin CA Stegh AH | 2015 | 中华神经外科疾病研究杂志2015，14，2： | 14 |

| 13 | Porcine Coronaviruses: Overview of the State of the Art显示文摘Like RNA viruses in general,coronaviruses(CoV)exhibit high mutation rates which,in combination with their strong tendency to recombine,enable them to overcome the host species barrier and adapt to new hosts.It is currently known that six CoV are able to infect pigs.Four of them belong to the genus Alphacoronavirus[transmissible gastroenteritis coronavirus(TEGV),porcine respiratory coronavirus(PRCV),porcine epidemic diarrhea virus(PEDV),swine acute diarrhea syndrome coronavirus(SADS-CoV)],one of them to the genus Betacoronavirus[porcine hemagglutinating encephalomyelitis virus(PHEV)]and the last one to the genus Deltacoronavirus(PDCoV).PHEV was one of the first identified swine CoV and is still widespread,causing subclinical infections in pigs in several countries.PRCV,a spike deletion mutant of TGEV associated with respiratory tract infection,appeared in the 1980 s.PRCV is considered nonpathogenic since its infection course is mild or subclinical.Since its appearance,pig populations have become immune to both PRCV and TGEV,leading to a significant reduction in the clinical and economic importance of TGEV.TGEV,PEDV and PDCoV are enteropathogenic CoV and cause clinically indistinguishable acute gastroenteritis in all age groups of pigs.PDCoV and SADS-CoV have emerged in 2014(US)and in 2017(China),respectively.Rapid diagnosis is crucial for controlling CoV infections and preventing them from spreading.Since vaccines are available only for some porcine CoV,prevention should focus mainly on a high level of biosecurity.In view of the diversity of CoV and the potential risk factors associated with zoonotic emergence,updating the knowledge concerning this area is essential. | Hanna Turlewicz-Podbielska Małgorzata Pomorska-Mo´l | 2021 | Virologica Sinica2021，36，5： | 12 |
| 14 | Ultra fast microwave-assisted leaching for the recovery of copper and tellurium from copper anode slime显示文摘The decomposition of copper anode slime heated by microwave energy in a sulfuric acid medium was investigated. Leaching experiments were carried out in a multi-mode cavity with microwave assistance. The leaching process parameters were optimized using response surface methodology(RSM). Under the optimized conditions, the leaching efficiencies of copper and tellurium were 99.56% ± 0.16% and 98.68% ± 0.12%, respectively. Meanwhile, a conventional leaching experiment was performed in order to evaluate the influence of microwave radiation. The mechanism of microwave-assisted leaching of copper anode slime was also investigated. In the results, the microwave technology is demonstrated to have a great potential to improve the leaching efficiency and reduce the leaching time. The enhanced recoveries of copper and tellurium are believed to result from the presence of a temperature gradient due to the shallow microwave penetration depth and the superheating at the solid-liquid interface. | Zhi-yuan Ma Hong-ying Yang Song-tao Huang Yang Lü Liu Xiong | 2015 | International Journal of Minerals,Metallurgy and Materials2015，22，6： | 11 |
| 15 | Structural coupling of the Dabie Orogen with Hefei Basin显示文摘Geological, geophysical and geochemical data show that both of the Dabie Orogen and Hefei Basin formed during a Mesozoic orogeny. A three-stage development of the Hefei Basin includes down-warping, half grabben, and positive inversion. Both the uplift in orogen and the depression in basin resulted from the 'de-rooting' of orogen and up-welling of the mantle. | Wang, QC Cong, B Ma, L | 1997 | Chinese Science Bulletin1997，42，18： | 10 |
| 16 | New aspects in celiac disease显示文摘Celiac disease (CD) is a common autoimmune disorder characterized by an immune response to ingested gluten and has a strong HLA association with HLA- DQ2 and HLA-DQ8 molecules, but human HLA-DQ risk factors do not explain the entire genetic susceptibility to gluten intolerance. CD is caused by the lack of immune tolerance (oral tolerance) to wheat gluten. In this sense, the expression of soluble HLA-G in CD is of special interest because the molecule plays an important role in the induction of immune tolerance. The enhanced expression of soluble HLA-G found in CD may be part of a mechanism to restore the gluten intolerance. In this editorial, we review recent progress in understanding CD in relation to its prevalence, diagnosis and possible mechanisms of pathogenesis. | MI Torres MA López Casado A Ríos | 2007 | World Journal of Gastroenterology2007，13，8： | 10 |
| 17 | 胡萝卜软腐果胶杆菌巴西亚种(Pectobacterium carotovorum subsp.brasiliense)引起的黄瓜细菌性软腐病在中国发生显示文摘2014—2015年,在中国山东、山西、河北、河南、辽宁等省的黄瓜茎叶上发生了毁灭性的细菌性软腐病,造成了黄瓜产业严重的经济损失。黄瓜叶片、茎、叶柄和果实表面出现流胶;茎基部呈深褐色进而出现湿腐。受侵染的黄瓜叶边缘出现黄斑和湿腐症状,并逐渐扩散至叶片中心。从受侵染组织中分离出45个细菌菌株,在形态学特性鉴定、生理学、生物化学和16Sr RNA基因序列分析的基础上,将病原体鉴定为胡萝卜软腐果胶杆菌(Pectobacterium carotovorum)。多位点序列分析(MLSA)证实,分离菌株是胡萝卜软腐果胶杆菌巴西亚种[Pectobacterium carotovorum subsp.brasiliensis(Pcb)],病原菌归入进化枝II。重新分离获得与原始菌株相同的菌株,证实了分离菌株的致病力。寄主范围测试表明,该菌株具有广泛的寄主范围。目前为止,这是对Pcb引起的黄瓜软腐病——这一对黄瓜生产具有重要经济影响的病害在中国乃至全球范围内的首次报道。 | 冯志琴(译) meng x l chai a l shi y x xie x w ma z h li b j | 2017 | 中国植保导刊2017，37，7： | 10 |
| 18 | Temporal and Spatial Distribution of the Late Devonian (Famennian) Strata in the Northwestern Border of the Junggar Basin, Xinjiang, Northwestern China显示文摘The base of the Saerba Member(Mbr) of the Hongguleleng Formation(Fm.) probably lies in the Famennian Palmatolepis crepida Zone;the Longkou Mbr is probably a sedimentary wedge that thins out northwards;the Duguer Mbr has an approximate age from the upper part of the Pa.marginifera Zone or the Lower Pa.rugosa trachytera Zone through the top of the Pa.perlobata postera Zone;the Wulan Mbr has an age approximately corresponding to the whole Pa.gracilis expansa Zone.In the Bulongguoer section,the Lower Mbr of the Hongguleleng Fm.corresponds to Famennian Pa.crepida Zone through Pa.marginifera Zone;the Middle Mbr probably ranges from the Pa.r.trachytera Zone through the Pa.g.expansa Zone.The basal Namu Mbr of the Heishantou Fm.is probably the product during and after the Hangenberg Event in the upper part of the Siphonodella praesulcata Zone,which is still within the Devonian.In this context,the underlying Chasi Mbr may approximately correspond to the lower part of the S.praesulcata Zone(before the Hangenberg Event).Lateral distribution of strata indicates that the Upper Devonian in the Gennaren and Saerba areas each constitutes a structure of syncline,which differs from the previous recognition of a monocline structure. | MA Xueping ZHANG Meiqiong ZONG Pu ZHANG Yubo Lü Dan | 2017 | Acta Geologica Sinica(English Edition)2017，91，4： | 9 |
| 19 | Field Measurements of Influence of Sand Transport Rate on Structure of Wind-sand Flow over Coastal Transverse Ridge显示文摘The structure of wind-sand flow under different total sand transport rates was measured with field vertical anemometer and sand trap on the crest of typical coastal transverse ridge in Changli Gold Coast of Hebei Province, which is one of the most typical coastal aeolian distribution regions in China and famous for the tall and typical coastal transverse ridges. The measurement results show that, on the conditions of approximate wind velocities and same surface materials and environments, some changes happen to the structure of wind-sand flow with the increase of total sand transport rate on the crest of coastal transverse ridge. First, the sand transport rates of layers at different heights in the wind-sand flow increase, with the maximum increase at the height layer of 4-8cm. Second, the ratios of sand trans-port rates of layers at different heights to total sand transport rate decrease at the low height layer (0-4cm), but increase at the high height layer (4-60cm). Third, the distribution of the sand transport rate in the wind-sand flow can be expressed by an exponential function at the height layer of 0-40cm, but it changes from power function model to ex-ponential function model in the whole height layer (0-60cm) and changes into polynomial function model at the height layer of 40-60cm with the increase of total sand transport rate. Those changes have a close relationship with the limit of sand grain size of wind flow transporting and composition of sand grain size in the wind-sand flow. | DONG Yuxiang S L NAMIKAS P A HESP MA Jun | 2008 | Chinese Geographical Science2008，18，3： | 9 |
| 20 | Mechanosignaling activation of TGFβmaintains intervertebral disc homeostasis显示文摘Intervertebral disc(IVD) degeneration is the leading cause of disability with no disease-modifying treatment.IVD degeneration is associated with instable mechanical loading in the spine, but little is known about how mechanical stress regulates nucleus notochordal(NC) cells to maintain IVD homeostasis. Here we report that mechanical stress can result in excessive integrin α_vβ_6-mediated activation of transforming growth factor beta(TGFβ), decreased NC cell vacuoles, and increased matrix proteoglycan production, and results in degenerative disc disease(DDD). Knockout of TGFβ type II receptor(TβRII) or integrin α_v in the NC cells inhibited functional activity of postnatal NC cells and also resulted in DDD under mechanical loading.Administration of RGD peptide, TGFβ, and α_vβ_6-neutralizing antibodies attenuated IVD degeneration. Thus,integrin-mediated activation of TGFβ plays a critical role in mechanical signaling transduction to regulate IVD cell function and homeostasis. Manipulation of this signaling pathway may be a potential therapeutic target to modify DDD. | Qin Bian Lei Ma Amit Jain Janet L Crane Khaled Kebaish Mei Wan Zhengdong Zhang X Edward Guo Paul D Sponseller Cheryle A Seguin Lee H Riley Yongjun Wang Xu Cao | 2017 | Bone Research2017，5，1： | 9 |
