1Adakite-type sodium-rich rocks in Awulale Mountain of west Tianshan:Significance for the vertical growth of continental crust显示文摘The sodium-rich dacites and albite porphyries of Permian in the Awulale Mountain of west Tianshan have unique chemical and trace element signatures identical to adakite. These intermediate-acidic igneous rocks are characterized by high Na2O, Al2O3 and Sr contents and high Sr/Y and La/Y ratios (>40 and >20, respectively), and low Y and Yb contents, and strong depletion in HREE, and positive Eu anomaly. The (143Nd/144Nd)i is in the range from0.51236 to 0.51248 and the εNd(t) is positive value (+0.79-+3.11); the (87Sr/86Sr)i is in the range from 0.7052 to 0.7054. These Nd and Sr isotopic composition features indicate that the source rocks of these adakite-type rocks are from a weakly depleted mantle, or a depleted mantle, but was contaminated by the crustal materials. These adakite-type rocks were most likely derived from the partial melting of new underplated basaltic rocks under the conditions of amphibo-lite to eclogite transition in the postcollisional environment of North Xinjiang during the PermianXIONG Xiaolin ZHAO Zhenhua BAI Zhenghua MEI Houjun WANG Yixian WANG Qiang XU Jifeng Niu Hecai BAO Zhiwei 2001Chinese Science Bulletin2001,46,10:25
2Geochemistry of Alkali-rich Igneous Rocks of Northern Xinjiang and Its Implications for Geodynamics显示文摘Five nearly E-W-trending alkali-rich igneous rock belts are distributed from north to south in northern Xinjiang, and they are composed mainly of riebeckite, K-feldspar granite and high-K and medium-K calc-alkaline volcanic rocks and shoshonite. They were mainly emplaced or erupted between the Carboniferous and Permian. The compositions of Sr, Nd, Pb, and O isotopes imply that their principal resource materials are derived from the upper mantle or juvenile crust, indicating obvious continental growth in the Phanerozoic. The trace element association implies that their tectonic settings are within plate and volcanic arc for alkali-rich granites, and post-collisional arc, late oceanic arc and continental arc for alkali-rich volcanic rocks. An archipelago model was suggested for the tectonic evolution in northern Xinjiang. It can be named the central-Asia-type orogeny, which is different from the so called circum-Pacific ocean-continent-type tectonics or the Alpine-HimalayanZHAO Zhenhua BAI Zhenghua XIONG Xiaolin MEI Houjun WANG Yixian 2000Acta Geologica Sinica(English Edition)2000,74,2:16
3Adakites related to subduc-tion in the northern margin of Junggar arc for the Late Paleozoic:Products of slab melting显示文摘Volcanic rocks with adakitic compositional signature have been recognized in the northern margin of ancient Junggar island arc for the Late Paleozoic. These adakites for the early Devonian from the Tuoranggekudouke Group (D1t) are characteristic of high Sr, Sr/Y and (La/Yb)N but low Y, Yb and HREE. Their compositional characteristics are much similar to those of the typical adakites in the world but distinct from those of the normal arc volcanic rocks from the same Group. We conclude that these adakitic volcanic rocks were produced by slab melting during the early period of Paleoasia-ocean lithosphere subduction. This infers that the Paleoasia Ocean in the north Junggar area began a new subduction process in the early Devonian.Jifeng Xu Houjun Mei Xueyuan Yu Zhenghua Bai Hecai Niu Fanrong Chen Zuoping Zhen Qiang Wang 2001Chinese Science Bulletin2001,46,15:11

5PagGRF12a interacts with PagGIF1b to regulate secondary xylem development through modulating PagXND1a expression in Populus alba×P.glandulosa显示文摘Growth-regulating factors(GRFs)are important regulators of plant development and growth,but their possible roles in xylem development in woody plants remain unclear.Here,we report that Populus alba×Papulus glandulosa PagGRF12a negatively regulates xylem development in poplar.PagGRF12a is expressed in vascular tissues.Compared to non-transgenic control plants,transgenic poplar plants overexpressing PagGRF12a exhibited reduced xylem width and plants with repressed expression of PagGRF12a exhibited increased xylem width.Xylem NAC domain 1(XND1)encodes a NAC domain transcription factor that regulates xylem development and transcriptional analyses revealed that PagXND1a is highly upregulated in PagGRF12a-overexpressing plants and downregulated in PagGRF12a-suppressed plants,indicating that PagGRF12a may regulate xylem development through PagXND1a.Transient transcriptional assays and chromatin immunoprecipitation-polymerase chain reaction assays confirmed that PagGRF12a directly upregulates PagXND1a.In addition,PagGRF12a interacts with the GRF-Interacting Factor(GIF)PagGIF1b,and this interaction enhances the effects of PagGRF12a on PagXND1a.Our results indicate that PagGRF12a inhibits xylem development by upregulating the expression of PagXND1a.Jinnan Wang Houjun Zhou Yanqiu Zhao Cheng Jiang Jihong Li Fang Tang Yingli Liu Shutang Zhao Jianjun Hu Xueqin Song MengZhu Lu 2021Journal of Integrative Plant Biology2021,63,10:3

7Problems of Family Farms in China and Countermeasures显示文摘In the Communiqué of the Third Plenary Session of the 18 th Central Committee of the CPC,it proposed the tasks of accelerating the building of a new type of agricultural operation system,endowing farmers with more property rights,promoting equal exchanges of factors of production and balanced allocation of public resources between urban and rural areas,and improving the institutions and mechanisms for promoting the sound development of urbanization. However,as new agricultural operating entities,family farms have problems of land circulation,lack of scientific and technological talents,and backward infrastructure. In line with these problems,this study put forward recommendations and countermeasures,in the hope of promoting increase in farmers' income,increasing agricultural intensification and large-scale level,and realizing agricultural modernization.Huamei LIN Houjun WANG 2014Asian Agricultural Research2014,6,6:1

19A Trust Assessment-Based Distributed Localization Algorithm for Sensor Networks Under Deception Attacks显示文摘Dear Editor,This letter is concerned with the distributed localization issue for wireless sensor networks subject to deception attacks.It is assumed that malicious nodes randomly launch attacks to tamper the ranging information between sensors.In order to accommodate the effects of deception attacks,a trust assessment-based distributed localization algorithm is proposed.Combined with data fusion of barycentric coordinates,our algorithm can achieve accurate localization.Finally,numerical simulations are given to validate the effectiveness of the proposed localization algorithm.Ya Wang Xinming Chen Lei Shi Yuhua Cheng Houjun Wang 2022IEEE/CAA Journal of Automatica Sinica2022,9,10:0
20Microecological Prevention and Control Technology of Facility Strawberry Continuous Cropping Diseases and Its Application Effects显示文摘In order to actively develop green ecological strawberry, the authors have studied integrated microecological prevention and control technologies of strawberry continuous cropping diseases, including increasing soil biomass and solar high temperature disinfection during strawberry greenhouse leisure period in summer, biological fertilizer (agent) treatment before colonization, root irrigation treatment with biocontrol agent, as well as appropriate amount of fulvic acid and cytex after colonization, forming a supporting technical system for the microecological prevention and control of soil-borne diseases in facilities. The demonstration application in production shows that the technology has the functions of restoring and enhancing soil biological fertility, enriching beneficial microbial flora, antagonizing harmful bacteria, significantly promoting the growth and development of strawberry, reducing the incidence of soil-borne diseases, reducing the use of chemical fertilizers and pesticides, promoting the early ripening and high yield of strawberry, significantly improving the quality and flavor of strawberry, reducing the risk of pesticide residues, and boosting consumer confidence, which further improves the economic benefit, social benefit and ecological benefit, with good application prospect in production.Houjun HE Jiexu HUANG Xiaolin WANG Yushan QIAO Muxiang JI 2022Plant Diseases and Pests2022,13,6:0
