3Zircon SHRIMP U-Pb geochronology,geochemistry and petrogenesis of the upper Eocene Shuangmaidi peraluminous granite in Baoshan Block,Western Yunnan Terrain,southwestern China显示文摘The Baoshan Block is tectonically located in the middle segment of the Sibumasu plate.Granitic magmatism within the Baoshan Block has been considered weakly active due mainly to very limited exposures during the Himalaya orogenic episode.The geochronological study on the buried Shuangmaidi granite has confirmed the existence of the Cenozoic granitoids in the Baoshan Block.The present study indicates that:(1) It is medium-to coarse-grained two mica phyric granite,characterized by high SiO 2 (73.55%-77.16%) and low CaO (0.34%-1.38%) contents,with a total alkalis (K 2 O+Na 2 O) of 5.22%-8.03%,K 2 O/Na 2 O ratios of 0.24-1.79,and total rare earth elements (ΣREE) of the granite between 85 and 125 ppb.All samples are enriched in light REE and exhibit medium negative Eu anomalies;and they show pronounced negative anomalies in Ba,Sr,Ti,and Nb but significant positive anomalies in K,Rb,U,Th,and Pb on mantle-normalized trace element patterns,indicating typi-cally peraluminous to strongly peraluminous S-type granite.(2) The zircon SHRIMP U-Pb ages of the granite are 36.27±0.48 Ma for the samples from ZK7-1 and 35.78±0.49 Ma for those from ZK0-1,respectively.The similar zircon ages from these two drill cores may suggest that the granite samples come from the same buried pluton.(3) 206 Pb/204 Pb values of the granite vary from 20.115 to 25.359,207 Pb/204 Pb from 15.776 to 16.160,and 208 Pb/204 Pb from 39.236 to 41.285,showing the characteristics of radio-active lead anomaly of the upper crust.The (87 Sr/86 Sr) i values calculated on the average age of the two-mica orthoclase granite (36 Ma) range from 0.72524 to 0.77503 and ε Nd (t) values vary from 10.9 to 11.7.These data,along with the depleted-mantle Nd modal ages of 1.73-1.80 Ga,imply that the granites might have formed from partial melting of the Precambrian crystal basements.(4) On the Hf-Rb-Ta diagram,almost all the samples fall within the field of post-collision tectonic setting.The CaO/Na 2 O and Al 2 O 3/TiO 2 ratios suggest that the granitic magma may have formed from partial melting of clay-rich crustal materials with a pos-sible melting temperature of about 900°C and a possible crystallization temperature of 775-795°C.(5) During the post-collision of the Himalaya orogen,with the southeastward extrusion of the Indochina continent resulting from the continuous northward indentation of the India continent into the Asia,the Gaoligong Fault,as the western boundary of the Indochina continent,moved in the dextral strike-slip on a large scale to trigger partial melting of the thickened crust,and the peraluminous granitic magma from which the Shuangmaidi two-mica orthoclase granite derived was formed.HUANG JingNing CHEN YongQing ZHAI XiaoMing LU YingXiang XIE YongFu CHENG ZhiZhong 2011Science China Earth Sciences2011,54,7:7

5Gamma-ray attenuation technique for measuring void fraction in horizontal gas-liquid two-phase flow显示文摘The measurement of void fraction is of importance to the oil industry and chemical industry. In this article, the principle and mathematical method of determining the void fraction of horizontal gas-liquid flow by using a sin- gle-energy γ-ray system is described. The γ-ray source is the radioactive isotope of 241Am with γ-ray energy of 59.5 keV. The time-averaged value of the void fraction in a 50.0-mm i.d. transparent horizontal pipeline is measured under various combinations of the liquid flow and gas flow. It is found that increasing the gas flow rate at a fixed liquid flow rate would increase the void fraction. Test data are compared with the predictions of the correlations and a good agreement is found. The result shows that the designed γ-ray system can be used for measuring the void fraction in a horizontal gas-liquid two-phase flow with high accuracy.LI Zhibiao WU Yingxiang LI Donghui 2007Nuclear Science and Techniques2007,18,2:6
6Experimental study of vortex-induced vibrations of a cylinder near a rigid plane boundary in steady flow显示文摘In this study,the vortex-induced vibrations of acylinder near a rigid plane boundary in a steady flow arestudied experimentally.The phenomenon of vortex-inducedvibrations of the cylinder near the rigid plane boundary isreproduced in the flume.The vortex shedding frequency andmode are also measured by the methods of hot film velocime-ter and hydrogen bubbles.A parametric study is carried out toinvestigate the influences of reduced velocity,gap-to-diame-ter ratio,stability parameter and mass ratio on the amplitudeand frequency responses of the cylinder.Experimental resultsindicate:(1)the Strouhal number(St)is around 0.2 for thestationary cylinder near a plane boundary in the sub-criti-cal flow regime;(2)with increasing gap-to-diameter ratio(e_0/D),the amplitude ratio(A/D)gets larger but frequencyratio(f/fn)has a slight variation for the case of larger val-ues of e_0/D(eo/D > 0.66 in this study);(3)there is a cleardifference of amplitude and frequency responses of the cylin-der between the larger gap-to-diameter ratios(e_0/D > 0.66)and the smaller ones(e_0/D < 0.3);(4)the vibration of thecylinder is easier to occur and the range of vibration in termsof V_r number becomes more extensive with decrease of thestability parameter,but the frequency response is affectedslightly by the stability parameter;(5)with decreasing mass ratio,the width of the lock-in ranges in terms of Vr and thefrequency ratio(f/fn)become larger.Bing Yang Fuping Gao Dong-Sheng Jeng Yingxiang Wu 2009Acta Mechanica Sinica2009,25,1:5

8Vitality evaluation of the waterfront space in the ancient city of Suzhou显示文摘With a history spanning thousands of years,the water system of Suzhou is an indispensable carrier of urban space and civil culture.Quantificational model analysis of the waterfront in the ancient city of Suzhou has significant implications for the future design of waterfront space and the establishment of an evaluation method to determine the vitality of such space.In this study,a vitality evaluation model was first constructed using river attributes,the spatial type of waterfront areas,vision accessibility,transportation accessibility,and combined new data extracted using spatial factor analysis.Second,a vitality evaluation matrix was established using the analytic hierarchy process to simulate the vitality of waterfront spaces.Third,a hash algorithm was employed to determine the fitting degree between the vitality model of Suzhou’s waterfront space and crowd activity.The different areas between them were found and then the factor evaluation process was adjusted on this basis of analyzing the causes.Thus,this study identified the factors influencing the vitality of Suzhou’s waterfront.Furthermore,this research constructed a model for evaluating the vitality of waterfront spaces.Finally,some guidelines were presented regarding the design and implementation of waterfront spaces in urban design.Yingxiang Niu Xiaoyan Mi Zhao Wang 2021Frontiers of Architectural Research2021,10,4:3
9Modulation of evening complex activity enables north-to-south adaptation of soybean显示文摘Soybean,a typical short-day crop,is sensitive to photoperiod,which is a major limiting factor defining its north-to-south cultivation range.The long-juvenile(LJ)trait is controlled primarily by the J locus which has been used for decades by soybean breeders to delay flowering and improve grain yield in tropical regions.The J gene encodes an ortholog of the Arabidopsis Evening Complex(EC)component EARLY FLOWERING 3(ELF3).To identify modifiers of J,we conducted a forward genetic screen and isolated a mutant(eoj57)that in combination with j has longer flowering delay compared with j single mutant plants.Map-based cloning and genome re-sequencing identified eoj57(designated as GmLUX2)as an ortholog of the Arabidopsis EC component LUX ARRHYTHMO(LUX).To validate that GmLUX2 is a modifier of J,we used trans-complementation and identified a natural variant allele with a similar phenotype.We also show that GmLUX2 physically interacts with GmELF3a/b and binds DNA,whereas the mutant and natural variant are attenuated in both activities.Transcriptome analysis shows that the GmLUX2-GmELF3a complex co-regulates the expression of several circadian clock-associated genes and directly represses E1 expression.These results provide mechanistic insight into how GmLUX2-GmELF3 controls flowering time via synergistic regulation of gene expression.These novel insights expand our understanding of the regulation of the EC complex,and facilitate the development of soybean varieties adapted for growth at lower latitudes.Xiaolong Fang Yapeng Han Mengshi Liu Jiacan Jiang Xiang Li Qichao Lian Xianrong Xie Yian Huang Qibin Ma Hai Nian Ji Qi Cunyi Yang Yingxiang Wang 2021Science China(Life Sciences)2021,64,2:3
10Geochronology and geochemistry of Cretaceous-Eocene granites,Tengchong Block(SW China):Petrogenesis and implications for Mesozoic-Cenozoic tectonic evolution of Eastern Tethys显示文摘The Early Cretaceous-Early Eocene granitoids in the Tengchong Block record the evolutionary history of the Mesozoic-Cenozoic tectono-magmatic evolution of Eastern Tethys.(a)The Early Cretaceous granitoids with relatively low(^(87)Sr/^(86)Sr)iratios of 0.7090-0.7169 andε_(Nd)(t)values of-9.8 to-7.8 display metaluminous,calc-alkaline dominated by I-type granite affinity and hybrid mantle-crust geochemical signatures.They may have been derived from melting of the subducted Meso-Tethyan BangongNujiang oceanic crust with terrigenous sediments in an arc-continent collisional setting.(b)The Late Cretaceous-Paleocene granitoids with relatively high(^(87)Sr/^(86)Sr)iratios of 0.7109-0.7627,andε_(Nd)(t)values of-12.1 to-7.9 exhibit metaluminous to peraluminous,calc-alkaline dominated by S-type granite affinity and hybrid Lower-Upper crust geochemical signatures,which may be originated from partial melting of the Meso-Proterozoic continental crust in the collision setting between the Tengchong Block and Baoshan Block.(c)The Early Eocene granitoids have metaluminous,calc-alkaline I-type and S-type granites dual affinity,with relatively high(^(87)Sr/^(86)Sr)iratios of 0.711-0.736,ε_(Nd)(t)values of-9.4 to-4.7,showing crust-mantle mixing geochemical signatures.They may have been originated from partial melting of the late Meso-Proterozoic upper crustal components mixed with some upper mantle material during the ascent process of mantle magma caused by the subduction of the Neo-Tethyan Putao-Myitkyian oceanic crust,and collision between the Western Burma Block and the Tengchong Block.It is these multi-stage subductions and collisions that caused the spatial and temporal distribution of the granitic rocks in the Tengchong Block.Yongqing Chen Guangjie Li Luxue Qin Yingxiang Lu Chengxing Jiang 2022Geoscience Frontiers2022,13,2:3

12High proton conductivity in metalloring-cluster based metalorganic nanotubes显示文摘Two novel anionic single-walled metal-organic nanotubes(MONTs),[(CH_(3))_(2)NH_(2)][ln(cdc)(thb)].2DMF.9.5H_(2)O(FJU-105)and[(CH_(3))_(2)NH_(2)][ln(cdc)(H-btc)]-2DMA·11H_(2)O(FJU-106)(H_(2)cdc=9H-carbazole-3,6-dicarboxylic acid,H_(2)thb=2,5-thiophene dicarboxylic acid,H3btc=1,3,5-benzene tricarboxylic acid),are achieved by employing[ln_(6)(cdc)_(6)]^(6+)metalloring cluster with largest diameter as the secondary building blocks(SBUs).The inner surface of FJU-106 is functionalized by uncoordinated-COOH groups of the H-btc linkers,leading to a higher proton conduction than FJU-105.At 70℃,FJU-106 displays the proton conduction performances among MONTs,up to 1.80×10^(-2)S·cm(^-1).And FJU-105 and FJU-106 are the first examples of MONT proton conductors operating at subzero temperature.Quanjie Lin Yingxiang Ye Lizhen Liu Zizhu Yao Ziyin Li Lihua Wang Chulong Liu Zhangjing Zhang Shengchang Xiang 2021Nano Research2021,14,2:2
13bZIP71 delays flowering by suppressing Ehd1 expression in rice显示文摘Flowering time is a fundamental factor determining the global distribution and final yield of rice(Oryza sativa).Although diverse flowering time genes have been reported in this crop,the transcriptional regulation of its key flowering genes are poorly understood.Here,we report that a basic leucine zipper transcription factor,bZIP71,functions as a flowering repressor.The overexpression of bZIP71 delays flowering,while the bzip71 mutant flowers early in both long-day and short-day conditions.A genetic analysis showed that the regulation of flowering by bZIP71 might be independent of Heading date 2(Hd2),Hd4,and Hd5.Importantly,bZIP71 directly associates with the Early heading date 1(Ehd1)promoter and represses its transcription,and genetically the function of bZIP71 is impaired in the ehd1 mutant.Moreover,bZIP71 interacts with major components of polycomb repressive complex 2(PRC2),SET domain group protein 711(SDG711),and Fertilization independent endosperm 2(FIE2),through which bZIP71 regulates the H3K27me3 level of Ehd1.Taken together,we present a transcriptional regulatory mechanism in which bZIP71 enhances the H3K27me3 level of Ehd1 and transcriptionally represses its expression,which not only offers a novel insight into a flowering pathway,but also provides a valuable putative target for the genetic engineering and breeding of elite rice cultivars.Xiufeng Li Xiaojie Tian Mingliang He Xinxin Liu Zhiyong Li Jiaqi Tang Enyang Mei Min Xu Yingxiang Liu Zhenyu Wang Qingjie Guan Wei Meng Jun Fang Jian Zhang Qingyun Bu 2022Journal of Integrative Plant Biology2022,64,7:2

17QNE1 is a key flowering regulator determining the length of the vegetative period in soybean cultivars显示文摘The soybean E1 gene is a major regulator that plays an important role in flowering time and maturity.However,it remains unclear how cultivars carrying the dominant E1 allele adapt to the higher latitudinal areas of northern China.We mapped the novel quantitative trait locus QNE1(QTL near E1) for flowering time to the region proximal to E1 on chromosome 6 in two mapping populations.Positional cloning revealed Glyma.06G204300,encoding a TCP-type transcription factor,as a strong candidate gene for QNE1.Association analysis further confirmed that functional single nucleotide polymorphisms(SNPs) at nucleotides 686 and 1,063 in the coding region of Glyma.06G204300 were significantly associated with flowering time.The protein encoded by the candidate gene is localized primarily to the nucleus.Furthermore,soybean and Brassica napus plants overexpressing Glyma.06G204300 exhibited early flowering.We conclude that despite their similar effects on flowering time,QNE1 and E4 may control flowering time through different regulatory mechanisms,based on expression studies and weighted gene co-expression network analysis of flowering time-related genes.Deciphering the molecular basis of QNE1 control of flowering time enriches our knowledge of flowering gene networks in soybean and will facilitate breeding soybean cultivars with broader latitudinal adaptation.Zhengjun Xia Hong Zhai Yanfeng Zhang Yaying Wang Lu Wang Kun Xu Hongyan Wu Jinglong Zhu Shuang Jiao Zhao Wan Xiaobin Zhu Yi Gao Yingxiang Liu Rong Fan Shihao Wu Xin Chen Jinyu Liu Jiayin Yang Qijian Song Zhixi Tian 2022Science China(Life Sciences)2022,65,12:1
