1U-Pb zircon dating of Early Paleozoic gabbro from the Nantinghe ophiolite in the Changning-Menglian suture zone and its geological implication显示文摘The Nantinghe ophiolite is located in the northern part of the Changning-Menglian suture zone in southeast Tibet. It is composed of meta-peridotite, cumulative gabbro, meta-gabbro, plagioclase amphibolite and meta-basalt. Zircon U-Pb dating of the cumulative gabbro gives concordant ages of 473.0±3.8 Ma and 443.6±4.0 Ma respectively, indicating the early and late episodes of mafic magmatisms during the Paleo-Tethys oceanic rifting. The 16 LA-ICPMS zircon U-Pb analyses of meta-gabbro yield a weight mean age of 439±2.4Ma. The gabbro shows relatively low contents of SiO2 (46.46%-52.11%), TiO2 (0.96%-1.14%) and K2O (0.48%-0.75%). Its trace element distribution patterns are partly similar to those of the mid-ocean ridge basalts, and part is depleted in high field strength elements such as Nb, Ta, Zr, Hf and Ti. These features suggest that the mafic rocks were probably formed in a MORB-like or backarc rift basin setting. The zircon U-Pb age of gabbro is consistent with a late crystallization age of the cumulative gabbro from the Nantinghe ophiolite, suggesting that the Paleo-Tethys oceanic basin was opened during 444-439 Ma, possibly as a backarc basin. It is the first precise age which defines the formation time of the early Paleozoic ophiolite in the Changning-Menglian suture zone. These geochronological and geochemical characteristics of the Nantinghe ophiolite are consistent with those from the Guoganjianianshan and Taoxinghu of the Longmu Co-Shuanghu suture in the Qiangtang region. Thus, we suggest that the both Changning-Menglian and Longmu Co-Shuanghu sutures were probably transformed from the relic oceanic crust of the uniform Paleo-Tethys, which likely represents the original and main Paleo-Tethys oceanic basin.WANG BaoDi WANG LiQuan PAN GuiTang YIN FuGuang WANG DongBing TANG Yuan 2013Chinese Science Bulletin2013,58,8:54
2Research and development of new neodymium laser glasses显示文摘This work presents a brief introduction on three kinds of newly developed Nd^(3+)-doped laser glasses in Shanghai Institute of Optics and Fine Mechanics(SIOM), China. Two Nd^(3+)-doped phosphate glasses with lower thermal expansion coefficient and thermal shock resistance 4 times higher than that of N31 glass are developed for laser processing.Nd:Silicate and Nd:Aluminate glasses with peak emission wavelength at 1061 and 1065 nm, effective emission bandwidth of 34 and 50 nm, respectively, are developed for Exawatt-class laser system application. Fluorophosphate glasses with low nonlinear refractive index(n_2=0.6–0.86) and long fluorescence lifetime(430–510 μs) are investigated for the purpose of decreasing B integral in high-power laser system. The properties of all these glasses are presented and compared with those of commercial neodymium laser glasses.Dongbing He Shuai Kang Liyan Zhang Lin Chen Yajun Ding Qianwen Yin Lili Hu 2017High Power Laser Science and Engineering2017,5,1:6
3Characterization and validation of somatic mutation spectrum to reveal heterogeneity in gastric cancer by single cell sequencing显示文摘Gastric cancer(GC) is a highly heterogeneous disease with multiple cellular types and poor prognosis.However, the cellular evolution and molecular basis of GC at the individual intra-tumor level has not been well demonstrated. We performed single-cell whole exome sequencing to detect somatic singlenucleotide variants(SNVs) and significantly mutated genes(SMGs) among 34 tumor cells and 9 normal cells from a patient with GC. The Complete Prediction for Protein Conformation(CPPC) approach directly predicting the folding conformation of the protein 3D structure with Protein Folding Shape Code, combined with functional experiments were used to confirm the characterization of mutated SMGs in GC cells. We identified 201 somatic SNVs, including 117 non-synonymous mutations in GC cells. Further analysis identified 24 significant mutated genes(SMGs) in single cells, for which a single amino acid change might affect protein conformation. Among them, two genes(CDC27 and FLG) that were mutated only in single cells but not in the corresponding tumor tissue, were recurrently present in another GC tissue cohort, and may play a potential role to promote carcinogenesis, as confirmed by functional characterization. Our findings showed a mutational landscape of GC at intra-tumor level for the first time and provided opportunities for understanding the heterogeneity and individualized target therapy for this disease.Lihua Peng Rui Xing Dongbing Liu Li Bao Wenxiang Cheng Hongyi Wang Yuan Yu Xiaofeng Liu Lu Jiang Yan Wu Zhongxue An Qiaoyi Liang Ryong Nam Kim Young Kee Shin Huanming Yang Jian Wang Jun Yu Xiuqing Zhang Xun Xu Jiaan Yang Kui Wu Shida Zhu Youyong Lu 2019Science Bulletin2019,64,4:3
4Control Effects of Jinggangmycin and Its Compounded Reagents against Rice Sheath Blight显示文摘The control effects of six kinds of reagents against rice sheath blight were compared in the test.The results showed that 24% thifluzamide SC 300 mL /hm 2 and 20% Jinggangmycin.prochloraz WP 750 g /hm 2 had good control effect against rice sheath blight,and their control effects after spraying for 7 and 14 d were 72.16%,77.91% and 66.52%,71.08%,respectively.The control effects of both reagents were significantly better than other test reagents and control reagent Jinggangmycin,and they had no adverse effect on growth and development of rice.Considering from the aspects of control effect and economy,20% Jinggangmycin.prochloraz WP was suggested to be used to control rice sheath blight,its recommended dosage was 600-750 g /hm 2,and the reagent volume was 750kg with coarse spraying.Zhaolin SHU Dongbing HE Kebing YAO Laicheng ZHAO Kang MIAO Hongfu YANG Muxiang JI 2012Plant Diseases and Pests2012,3,3:2

6Polymerization Kinetics and Stabilization Mechanism of the Monodisperse PMMA Microspheres显示文摘The effects of the concentration of monomer, crosslinking agent, initiator, stabilizer, and the polarity of medium on the polymerization kinetics were investigated. The results show that the rate of polymerization (Rp) and conversion increased with the increase of monomer concentration from 8% to 15% (total mass); the water content in dispersion medium and the initiator 2, 2′ -azobis (isobutyronitrile) (AIBN) concentration increased as well. Rp and conversion decreases with the increase of PVP when it is low, while it increases when it is high. Moreover, PVP plays an important role in microsphere stabilization. The stabilization mechanism was investigated primarily, which involves both adsorbing mechanism and graft mechanism. Within a certain range of crosslinking degree, Rp and conversion increased with the increase of the crosslinker concentration. The effect can be ignored when crosslinker concentration is above 0.3 % (total mass), and the reason was that the monomer can hardly be diffused into the microsphere phase with a certain degree of crosslinking.YU Xianglin YE Chunjie LI Junbo CHENG Dongbing WANG Jun CHEN Rong 2011Wuhan University Journal of Natural Sciences2011,16,4:2

11Multi-Modality Video Representation for Action Recognition显示文摘Nowadays,action recognition is widely applied in many fields.However,action is hard to define by single modality information.The difference between image recognition and action recognition is that action recognition needs more modality information to depict one action,such as the appearance,the motion and the dynamic information.Due to the state of action evolves with the change of time,motion information must be considered when representing an action.Most of current methods define an action by spatial information and motion information.There are two key elements of current action recognition methods:spatial information achieved by sampling sparsely on video frames’sequence and the motion content mostly represented by the optical flow which is calculated on consecutive video frames.However,the relevance between them in current methods is weak.Therefore,to strengthen the associativity,this paper presents a new architecture consisted of three streams to obtain multi-modality information.The advantages of our network are:(a)We propose a new sampling approach to sample evenly on the video sequence for acquiring the appearance information;(b)We utilize ResNet101 for gaining high-level and distinguished features;(c)We advance a three-stream architecture to capture temporal,spatial and dynamic information.Experimental results on UCF101 dataset illustrate that our method outperforms other previous methods.Chao Zhu Yike Wang Dongbing Pu Miao Qi Hui Sun Lei Tan 2020Journal on Big Data2020,2,3:1

17Bimodal PE prepared with combined iron (II) and nickel (II) olefin polymerization catalysts显示文摘Combined iron (II) and nickel (II) olefin polymerization catalysts could produce a kind of PE having the characters of ideal bimodal PE with ap- propriate conditions and catalysts. In the ethylene homopolymerization with triethylalkylaluminum (AlEt3) as the activator, the prepared bimodal PE contained not only branched PE of high molecular weight, but also linear PE of low molecular weight. And the amounts of both fractions were similar. Ideal bimodal PE resin was prepared in one polymerization reactor.WANG Shibo LIU Dongbing XU Renwei MAO Bingquan 2006Chinese Science Bulletin2006,51,1:1
