1Xiba Granitic Pluton in the Qinling Orogenic Belt, Central China: Its Petrogenesis and Tectonic Implications显示文摘Xiba granitic pluton is located in South Qinling tectonic domain of the Qinling orogenic belt and consists mainly of granodiorite and monzogranite with significant number of microgranular quartz dioritic enclaves. SHRIMP zircon U-Pb isotopic dating reveals that the quartz dioritic enclaves formed at 214±3 Ma, which is similar to the age of their host monzogranite (218±1 Ma). The granitoids belong to high-K calc-alkaline series, and are characterized by enriched LILEs relative to HFSEs with negative Nb, Ta and Ti anomalies, and right-declined REE patterns with (La/Yb) N ratios ranging from 15.83 to 26.47 and δEu values from 0.78 to 1.22 (mean= 0.97). Most of these samples from Xiba granitic pluton exhibit εNd(t) values of 8.79 to 5.38, depleted mantle Nd model ages (T DM ) between 1.1 Ga and 1.7 Ga, and initial Sr isotopic ratios ( 87 Sr/ 86 Sr) i from 0.7061 to 0.7082, indicating a possible Meso-to Paleoproterozoic lower crust source region, with exception of samples XB01-2-1 and XB10-1 displaying higher ( 87 Sr/ 86 Sr) i values of 0.779 and 0.735, respectively, which suggests a contamination of the upper crustal materials. Quartz dioritic enclaves are interpreted as the result of rapid crystallization fractionation during the parent magmatic emplacement, as evidenced by similar age, texture, geochemical, and Sr-Nd isotopic features with their host rocks. Characteristics of the petrological and geochemical data reveal that the parent magma of Xiba granitoids was produced by a magma mingling process. The upwelling asthenosphere caused a high heat flow and the mafic magma was underplated into the bottom of the lower continent crust, which caused the partial melting of the lower continent crustal materials. This geodynamic process generated the mixing parent magma between mafic magma from depleted mantle and felsic magma derived from the lower continent crust. Integrated petrogenesis and tectonic discrimination with regional tectonic evolution of the Qinling orogen, it is suggested that the granitoids are most likely products in a post-collision tectonic setting.ZHANG Fan LIU Shuwen CHEN Xu LI Qiugen DAI Junzhi YANG Kai WU Fenghui CHEN Youzhang 2012Acta Geologica Sinica(English Edition)2012,86,5:13
2Waste oyster shell as a kind of active filler to treat the combined wastewater at an estuary显示文摘Estuaries have been described as one of the most difcult environments on Earth. It is difcult to know how to treat the combined wastewater in tidal rivers at the estuary, where the situation is very diferent from ordinary fresh water rivers. Waste oyster shell was used as the active filler in this study in a bio-contact oxidation tank to treat the combined wastewater at the Fengtang Tidal River. With a middle-experimental scale of 360 m3/day, the average removal efciency of COD, BOD, NH3-N, TP and TSS was 80.05%, 85.02%,86.59%, 50.58% and 85.32%, respectively, in this bio-contact oxidation process. The living microbes in the biofilms on the waste oyster shell in this bio-contact oxidation tank, which were mainly composed of zoogloea, protozoa and micro-metazoa species, revealed that waste oyster shell as the filler was suitable material for combined wastewater degradation. This treatment method using waste oyster shell as active filler was then applied in a mangrove demonstration area for water quality improvement near the experiment area, with a treatment volume of 5 × 103m3/day. Another project was also successfully applied in a constructed wetland, with a wastewater treatment volume of 1 × 103m3/day. This technology is therefore feasible and can easily be applied on a larger scale.Hongbing Luo Gu Huang Xiaoying Fu Xiaoling Liu Daocai Zheng Jian Peng Ke Zhang Bo Huang Liangqian Fan Fenghui Chen Xiubo Sun 2013Journal of Environmental Sciences2013,25,10:11
3Convergence of multi-block Bregman ADMM for nonconvex composite problems显示文摘The alternating direction method with multipliers(ADMM) is one of the most powerful and successful methods for solving various composite problems. The convergence of the conventional ADMM(i.e.,2-block) for convex objective functions has been stated for a long time, and its convergence for nonconvex objective functions has, however, been established very recently. The multi-block ADMM, a natural extension of ADMM, is a widely used scheme and has also been found very useful in solving various nonconvex optimization problems. It is thus expected to establish the convergence of the multi-block ADMM under nonconvex frameworks. In this paper, we first justify the convergence of 3-block Bregman ADMM. We next extend these results to the N-block case(N≥3), which underlines the feasibility of multi-block ADMM applications in nonconvex settings. Finally, we present a simulation study and a real-world application to support the correctness of the obtained theoretical assertions.Fenghui WANG Wenfei CAO Zongben XU 2018Science China(Information Sciences)2018,61,12:9
4Anti-infectious efficacy of essential oil from Caoguo(Fructus Tsaoko)显示文摘OBJECTIVE: To evaluate the anti-infectious efficacy of essential oil extracted from Caoguo(Fructus Tsaoko).METHODS: Minimum inhibitory concentrations(MICs) against clinical isolates of three extracts andthe essential oil from Caoguo(Fructus Tsaoko) were determined by the agar dilution method. The anti-infectious efficacy of the essential oil was evaluated using a mouse peritonitis model which was infected with Staphylococcus aureus or Escherichia coli. The chemical components of the essential oil were identified.RESULTS: The results showed that the essential oil exhibited strong antibacterial activity in vitro, with MICs ranging from 22.49 to 1438.91 μg/m L. The results of in vivo anti-infectious efficacy showed that the Caoguo(Fructus Tsaoko) essential oil can protect the mice from Staphylococcus aureus or Escherichia coli infection. The compositions of the essential oil and relative component percentages were examined. A total of 32 compounds, were identified. The major compounds of essential oil were 1,8-cineole(25.92%) and geraniol(13.69%).CONCLUSION: Our findings suggest that Caoguo(Fructus Tsaoko) essential oil has broad-spectrum antibacterial properties. It warrants further investigation as an antibacterial agent targeting some bacterium with multi-drug resistance.Dai Min Peng Cheng Sun Fenghui 2016Journal of Traditional Chinese Medicine2016,36,6:6
5A unique hormonal recognition feature of the human glucagon-like peptide-2 receptor显示文摘Glucagon-like peptides(GLP-1 and GLP-2)are two proglucagon-derived intestinal hormones that mediate distinct physiological functions through two related receptors(GLP-1R and GLP-2R)which are important drug targets for metabolic disorders and Crohn's disease,respectively.Despite great progress in GLP-1 R structure determination,our understanding on the differences of peptide binding and signal transduction between these two receptors remains elusive.Here we report the electron microscopy structure of the human GLP-2R in complex with GLP-2 and a Gs heterotrimer.To accommodate GLP-2 rather than GLP-1,GLP-2R fine-tunes the conformations of the extracellular parts of transmembrane helices(TMs)1,5,7 and extracellular loop 1(ECL1).In contrast to GLP-1,the N-terminal histidine of GLP-2 penetrates into the receptor core with a unique orientation.The middle region of GLP-2 engages with TM1 and TM7 more extensively than with ECL2,and the GLP-2 C-terminus closely attaches to ECL1,which is the most protruded among 9 class B G protein-coupled receptors(GPCRs).Functional studies revealed that the above three segments of GLP-2 are essential for GLP-2 recognition and receptor activation,especially the middle region.These results provide new insights into the molecular basis of ligand specificity in class B GPCRs and may facilitate the development of more specific therapeutics.Wen Sun Li-Nan Chen Qingtong Zhou Li-Hua Zhao Dehua Yang Huibing Zhang Zhaotong Cong Dan-Dan Shen Fenghui Zhao Fulai Zhou Xiaoqing Cai Yan Chen Yan Zhou Sarina Gadgaard Wijnand JCvan der Velden Suwen Zhao Yi Jiang Mette MRosenkilde HEric Xu Yan Zhang Ming-Wei Wang 2020Cell Research2020,30,12:4
6Elemental Content in Brown Rice by Inductively Coupled Plasma Atomic Emission Spectroscopy Reveals the Evolution of Asian Cultivated Rice显示文摘The phylogenetic relationship for classification traits and eight mineral elements in brown rice(Oryza sativa L.) from Yunnan Province in China was carried out using microwave assisted digestion followed by inductively coupled plasma atomic emission spectroscopy,and the analytical procedures were carefully controlled and validated.In general,the results show that the mean levels of K,Ca,Mg,Fe and Cu in brown rice for 789 accessions of rice landraces was distinctly lower than that of improved cultivars.They further demonstrate that Ca plays an important role in the differentiation of subspecies indica-japonica,especially to enhance adaptation of cold stress,and that five mineral elements in brown rice enhance the eurytopicity from landrace to improved cultivar.Hierarchical cluster analysis,using average linkage from SPSS software based on eight mineral elements in brown rice,showed that Yunnan rice could be grouped into rice landrace and improved cultivar,with the rice landrace being further clustered into five subgroups,and that,interestingly,purple rice does not cluster with either of the groups.Our present data confirm that indica is the closest relative of late rice and white rice,and that they constitute rice landraces together,whereas japonica is the closest relatives of non-nuda,early-mid and glutinous rice.It is further shown that japonica,non-nuda,early-mid,glutinous,white and red rice might be more primitive than indica,nuda,late,non-glutinous and purple rice,respectively.Yawen Zeng Luxiang Wang Juan Du Jiafu Liu Shuming Yang Xiaoying Pu Fenghui Xiao 2009Journal of Integrative Plant Biology2009,51,5:4
7Regulation of impedance matching feature and electronic structure of nitrogen-doped carbon nanotubes for high-performance electromagnetic wave absorption显示文摘In this study,we developed a facile method to fabricate three-dimensional(3D)structures composed of FeNi alloy nanoparticles encapsulated in N-doped carbon nanotubes that grafted on the SiO_(2) spheres(Fe_(x)Ni_(y)@NCNT@SiO_(2))for electromagnetic wave(EMW)absorption.The experimental results suggest that the impedance matching characteristic can be tuned by the introduction of SiO_(2) spheres in the 3D structure.Density functional theory(DFT)calculations showed that the introduction of Ni improved the polarization and conductive losses of the Fe_(x)Ni_(y)@NCNT@SiO_(2).As a result,the optimal 3D structure exhibits excellent EMW absorption property with a reflection loss and effective absorption bandwidth are-49.39 dB and 4.32 GHz,respectively,even though the matching thickness is only 1.6 mm,superior to most magnetic carbon-based composites.Thus,our current approach opens up an effective way to the development of low-cost,high-performance EMW absorbers.Fenghui Cao Jia Xu Minjie Liu Feng Yan Qiuyun Ouyang Xitian Zhang Xiaoli Zhang Yujin Chen 2022Journal of Materials Science & Technology2022,,13:3
8Wnt5a Plays Controversial Roles in Cancer Progression显示文摘WntSa is a representative Wnt ligand that regulates multiple cellular functions through the Wnt5a nonclassical pathway.Although Wnt5a has been implicated in various pathological conditions,its role in cancer is ambiguous and might involve methyl modifications,distinct mRNA isofbrms,as well as different downstream pathways.Therefore,it is an essential factor in cancers'progression(invasion,migration,proliferation,and epithelial-mesenchymal transition),and a potential biomarker for prognosis and treatment.Xu Chen Hongling Liu Fenghui Zhao Zongxian Jiao Jinsui Wang Yamei Dang 2020Chinese Medical Sciences Journal2020,35,4:2

18An Agent-based Adaptive Mechanism for Efficient Job Scheduling in Open and Large-scale Environments显示文摘Agent-based scheduling refers to applying intelligent agents to autonomously allocate resources to jobs.Decentralized agent-based scheduling approaches have achieved good performance in open and dynamic environments because the relationships of agents are flexible.For new jobs and resources and unexpected events,decentralized agents can respond adaptively and flexibly.Besides,decentralized approaches are easy to be extended because there is no central control agent that limits the scalability.However,decentralized approaches might have low efficiency in large-scale environments because behaviors of agents may be self-interested and competitive,due to their local views during decision making.When interacting with a large number of agents,each agent may spend a considerable amount of time on failed attempts before reaching the final agreements with other agents.To improve the efficiency of decentralized agent-based scheduling approaches in large-scale environments,and to keep the flexibility and adaptability of decentralized agents for the decision-making on scheduling,this paper provides a new agent-based adaptive mechanism for efficient job scheduling.A new type of agent named host agent is introduced to coordinate self-interested behaviors of agents without participating in the decision making of agents during job scheduling.The proposed mechanism was developed in JADE and tested in open and large-scale environments.The experimental results indicate that the proposed mechanism is effective and efficient in open and large-scale environments.Yikun Yang Fenghui Ren Minjie Zhang 2021Journal of Systems Science and Systems Engineering2021,30,4:1
