1Magma mixing of granites at Lianghe:In-situ zircon analysis for trace elements, U-Pb ages and Hf isotopes显示文摘In this paper, we report an integrated study of trace element, U-Pb age and Hf isotopic composition of zircons from alkali feldspar granites, granodiorites and diorite enclaves in a recently discovered ring complex at Lianghe in western Yunnan, Chi na. The granitoids showed identical U-Pb ages of 127, 115 and 122 Ma, from felsic to mafic, but had different zircon trace el ements and Hf isotopic compositions. Trace element content decreased with a gradual increase in εHf(t) values of ?9.1 to ?5.4, ?4.5 to 0, and 3.6 to 6.2, respectively. Results indicate that changes in zircon trace elements generally correlate with changes in Hf isotope signatures within single samples and among various granitoids. These relationships reflect the mixing of felsic and mafic magmas. Evidence indicates that depleted mantle-derived mafic magma underplating caused ancient crustal melting, and then formed large-scale granites in Lianghe during the Early Cretaceous. These granodiorites were formed mainly by the mix ing of mafic magma and granitic magma.CONG Feng LIN ShiLiang ZOU GuangFu LI ZaiHui XIE Tao PENG ZhiMin LIANG Ting 2011Science China Earth Sciences2011,54,9:26

3Molecular evolution and functional divergence of HAK potassium transporter gene family in rice(Oryza sativa L.)显示文摘The high-affinity K+(HAK) transporter gene family is the largest family in plant that functions as potassium transporter and is impor-tant for various aspects of plant life.In the present study,we identified 27 members of this family in rice genome.The phylogenetic tree divided the land plant HAK transporter proteins into 6 distinct groups.Although the main characteristic of this family was established before the origin of seed plants,they also showed some differences between the members of non-seed and seed plants.The HAK genes in rice were found to have expanded in lineage-specific manner after the split of monocots and dicots,and both segmental duplication events and tandem duplication events contributed to the expansion of this family.Functional divergence analysis for this family provided statis-tical evidence for shifted evolutionary rate after gene duplication.Further analysis indicated that both point mutant with positive selection and gene conversion events contributed to the evolution of this family in rice.Zefeng Yang Qingsong Gao Changsen Sun Wenjuan Li Shiliang Gu Chenwu Xu 2009Journal of Genetics and Genomics2009,36,3:21
4Flotation separation of calcareous minerals using didodecyldimethylammonium chloride as a collector显示文摘The flotation separation of scheelite from fluorite and calcite using dodecyltrimethylammonium chloride(DTAC),dodecyldimethylbenzylammonium chloride(DDBAC),or didodecyldimethylammonium chloride(DDDAC) as the collector has been investigated.The results show that the selectivity of these collectors for these three calcareous minerals falls in the order:DDDAC > DDBAC > DTAC.A significantly different flotation response of scheelite compared to the other two calcareous minerals was observed over the pH range from 7 to 8 for DDDAC as the collector.A concentrate containing 41.40% WO3 could be produced from a feed mixture containing 23.22% WO3 at the DDDAC concentration of 4.0 10à4 mol/L.The WO3 recovery was 92.92% under these conditions.The results of zeta potential measurements suggest that electrostatic interactions are the main forces between DDDAC and the minerals.When the concentration of DDDAC is from 2 10à4 to 4 10à3 mol/L large differences in adsorption density,and adsorption kinetics,of DDDAC onto scheelite,calcite,and fluorite provide desirable conditions for achieving high selectivity.Zhang Ying Wang Yuhua Li Shiliang 2012International Journal of Mining Science and Technology2012,22,2:18
5Phylogeny and Classifcation of Prunus sensu lato (Rosaceae)显示文摘The classifcation of the economically important genus Prunus L.sensu lato(s.l.)is controversial due to the high levels of convergent or the parallel evolution of morphological characters.In the present study,phylogenetic analyses of ffteen main segregates of Prunus s.l.represented by eighty-four species were conducted with maximum parsimony and Bayesian approaches using twelve chloroplast regions(atpB-rbcL,matK,ndhF,psbA-trnH,rbcL,rpL16,rpoC1,rps16,trnS-G,trnL,trnL-F and ycf1)and three nuclear genes(ITS,s6pdh and SbeI)to explore their infrageneric relationships.The results of these analyses were used to develop a new,phylogeny-based classifcation of Prunus s.l.Our phylogenetic reconstructions resolved three main clades of Prunus s.l.with strong supports.We adopted a broad-sensed genus,Prunus,and recognised three subgenera corresponding to the three main clades:subgenus Padus,subgenus Cerasus and subgenus Prunus.Seven sections of subgenus Prunus were recognised.The dwarf cherries,which were previously assigned to subgenus Cerasus,were included in this subgenus Prunus.One new section name,Prunus L.subgenus Prunus section Persicae(T.T.Yü&L.T.Lu)S.L.Zhou and one new species name,Prunus tianshanica(Pojarkov)S.Shi,were proposed.Shuo Shi Jinlu Li Jiahui Sun Jing Yu Shiliang Zhou 2013Journal of Integrative Plant Biology2013,55,11:18

7Enhancing photocatalytic performance by constructing ultrafine TiO2 nanorods/g-C3N4 nanosheets heterojunction for water treatment显示文摘Photocatalysis is considered to be a clean, green and efficient method to purify water. In this report, we first developed a highly efficient ultrafine TiO_2 nanorods/g-C3 N4 nanosheets(TiO_2 NR/CN NS) composites via a simple hydrothermal method. Tiny TiO_2 nanorods(diameter:~1.5 nm and length:~8.3 nm) were first loaded in situ on the CN NS by adding graphitic carbon nitride(g-C3 N4) to the reaction solution.The TiO_2 NR/CN NS composites present high charge separation efficiency and broader light absorbance than P25 TiO_2. Furthermore, we illustrate that the Ti0_2 NR/CN NS catalyst possesses high performance for the photocatalytic degradation of the common and stubborn pollutants in water, such as the rhodamine B(RhB) dye and phenol. Under visible light(λ> 420 nm) irradiation, the apparent rate of the TiO_2 NR/CN NR is 172 and 41 times higher than that of the P25 TiO_2 and TiO_2 NR, respectively.Additionally, we speculated that the heterojunction formed between TiO_2 NR and CN NS, which is the basis for the experiments we have designed and the corresponding results. We demonstrated that reactive oxidative species such as superoxide anion radical and holes play critical roles in the degradation,and the hydroxyl radical contributes nothing to the degradation.Shiliang Luan Dan Qu Li An Wenshuai Jiang xiang Gao Shixin Hua Xiang Miao Yuanjing Wen Zaicheng Sun 2018Science Bulletin2018,63,11:16
8Effect of temperature,salinity and irradiance on growth and photosynthesis of Ulva prolifera显示文摘Intensive Pyropia aquaculture in the coast of southwestern Yellow Sea and its subsequent waste, including disposed Ulva prolifera, was speculated to be one of the major sources for the large-scale green tide proceeding in the Yellow Sea since 2007. It was, however, unclear how the detached U. prolifera responded and resumed growing after they detached from its original habitat. In this study, we investigated the growth and photosynthetic response of the detached U. prolifera to various temperature, salinity and irradiance in the laboratory. The photosynthetic rate of the detached U. prolifera was significantly higher at moderate temperature levels(14–27°C)and high salinity(26–32), with optimum at 23°C and 32. Both low(<14°C) and highest temperature(40°C), as well as low salinity(8) had adverse effects on the photosynthesis. Compared with the other Ulva species, U. prolifera showed higher saturated irradiance and no significant photoinhibition at high irradiance, indicating the great tolerance of U. prolifera to the high irradiance. The dense branch and complex structure of floating mats could help protect the thalli and reduce photoinhibition in field. Furthermore, temperature exerted a stronger influence on the growth rate of the detached U. prolifera compared to salinity. Overall, the high growth rate of this detached U. prolifera(10.6%–16.7% d^(–1)) at a wide range of temperature(5–32°C) and salinity(14–32) implied its blooming tendency with fluctuated salinity and temperature during floating. The environmental parameters in the southwestern Yellow Sea at the beginning of green tide were coincident with the optimal conditions for the detached U. prolifera.XIAO Jie ZHANG Xiaohong GAO Chunlei JIANG Meijie LI Ruixiang WANG Zongling LI Yan FAN Shiliang ZHANG Xuelei 2016Acta Oceanologica Sinica2016,35,10:14
9Novel and potent inhibitors targeting DHODH are broad-spectrum antivirals against RNA viruses including newly-emerged coronavirus SARS-CoV-2显示文摘Emerging and re-emerging RNA viruses occasionally cause epidemics and pandemics worldwide,such as the on-going outbreak of the novel coronavirus SARS-CoV-2.Herein,we identified two potent inhibitors of human DHODH,S312 and S416,with favorable drug-likeness and pharmacokinetic profiles,which all showed broad-spectrum antiviral effects against various RNA viruses,including influenza A virus,Zika virus,Ebola virus,and particularly against SARS-CoV-2.Notably,S416 is reported to be the most potent inhibitor so far with an EC5o of 17 nmol/L and an SI value of 10,505.88 in infec-ted cells.Our results are the first to validate that DHODH is an attractive host target through high antiviral efficacy in vivo and low virus replication in DHODH knock-out cells.This work demonstrates that both S312/S416 and old drugs(Leflunomide/Teriflunomide)with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide,no matter such viruses are mutated or not.Rui Xiong Leike Zhang Shiliang Li Yuan Sun Minyi Ding Yong Wang Yongliang Zhao Yan Wu Weijuan Shang Xiaming Jiang Jiwei Shan Zihao Shen Yi Tong Liuxin Xu Yu Chen Yingle Liu Gang Zou Dimitri Lavillete Zhenjiang Zhao Rui Wang Lili Zhu Gengfu Xiao Ke Lan Honglin Li Ke Xu 2020Protein & Cell2020,11,10:14
10Protonation induced high-T_c phases in iron-based superconductors evidenced by NMR and magnetization measurements显示文摘Chemical substitution during growth is a well-established method to manipulate electronic states of quantum materials, and leads to rich spectra of phase diagrams in cuprate and iron-based superconductors. Here we report a novel and generic strategy to achieve nonvolatile electron doping in series of(i.e.11 and 122 structures) Fe-based superconductors by ionic liquid gating induced protonation at room temperature. Accumulation of protons in bulk compounds induces superconductivity in the parent compounds, and enhances the Tclargely in some superconducting ones. Furthermore, the existence of proton in the lattice enables the first proton nuclear magnetic resonance(NMR) study to probe directly superconductivity. Using Fe S as a model system, our NMR study reveals an emergent high-Tcphase with no coherence peak which is hard to measure by NMR with other isotopes. This novel electric-fieldinduced proton evolution opens up an avenue for manipulation of competing electronic states(e.g.Mott insulators), and may provide an innovative way for a broad perspective of NMR measurements with greatly enhanced detecting resolution.Yi Cui Gehui Zhang Haobo Li Hai Lin Xiyu Zhu Hai-Hu Wen Guoqing Wang Jinzhao Sun Mingwei Ma Yuan Li Dongliang Gong Tao Xie Yanhong Gu Shiliang Lie Huiqian Luo Pu Yu Weiqiang Yu 2018Science Bulletin2018,63,1:7
11Ultrafast optical spectroscopy evidence of pseudogap and electronphonon coupling in an iron-based superconductor KCa_(2)Fe_(4)As_(4)F_(2)显示文摘We use ultrafast optical spectroscopy to study the nonequilibrium quasiparticle relaxation dynamics of the iron-based superconductor KCa_(2)Fe_(4)A_(s4)F_(2)with T_(c)= 33.5 K. Our results reveal a possible pseudogap(△_(PG)=(2.4 ± 0.1) me V) below T*≈ 50 K but prior to the opening of a superconducting gap(△SC(0) ≈(4.3 ± 0.1) me V). Measurements under high pump fluence reveal two distinct, coherent phonon oscillations with 1.95 and 5.51 THz frequencies, respectively. The high-frequency A1 g(2) mode corresponds to the c-axis polarized vibrations of Fe As planes with a nominal electron-phonon coupling constant λA1 g(2)= 0.194 ± 0.02.Our findings suggest that the pseudogap is likely a precursor of superconductivity, and the electron-phonon coupling may play an essential role in the superconducting pairing in KCa_(2)Fe_(4)A_(s4)F_(2).Chen Zhang Qi-Yi Wu Wen-Shan Hong Hao Liu Shuang-Xing Zhu Jiao-Jiao Song Yin-Zou Zhao Fan-Ying Wu Zi-Teng Liu Shu-Yu Liu Ya-Hua Yuan Han Huang Jun He Shiliang Li Hai-Yun Liu Yu-Xia Duan Hui-Qian Luo Jian-Qiao Meng 2022Science China(Physics,Mechanics & Astronomy)2022,65,3:7
12Community structure and controlled factor of attached green algae on the Porphyra yezoensis aquaculture rafts in the Subei Shoal, China显示文摘This study analyzes the community structure, the quantity changes of the algae and the effect of important environmental factors and estimates the total biomass of the attached green algae in the survey areas. The study uses data from surveys of the attached green algae on the Porphyra yezoensis aquaculture rafts and data regarding the environmental factors from October 2010 to April 2011 in the Subei Shoal. The attached green algae on the rafts included Ulva prolifera, Capsosiphon groenlandicus, U. linza, U. intestinalis, U. clathrata, and U. compressa.The biomass changes of the attached green algae exhibited an inverted parabola: the biomass was the highest(14 898 t) in April, and was the second highest(2 034 t) in November; it was lowest in February(only 729 t) and increased sharply from March to April. The species diversity differed significantly among the seasons. In September and October, when the P. yezoensis aquaculture rafts were initially set up, the attached green algae had a high biodiversity, while from December to the next February, a variety of green algae species coexisted on the rafts, although the biomass was low, and from March to April, as the biomass increased sharply, the species diversity dropped to the minimum. During this time, C. groenlandicus was apparently dominant with the maximum biomass proportion up to 80%, while the U. prolifera proportion increased exponentially to 20% to 40%.The water temperature had a direct regulating effect on the biomass and the species succession of the attached green algae. The estimation of the community dynamics and the biomass of the green algae provided the evidence needed to track the origin of the large-scale green tide in the southern Yellow Sea.LI Yan XIAO Jie DING Lanping WANG Zongling SONG Wei FANG Song FAN Shiliang LI Ruixiang ZHANG Xuelei 2015Acta Oceanologica Sinica2015,34,8:6
13Arbitrary focusing lens by holographic metasurface显示文摘In this paper, an ultrathin metalens has been proposed based on a holographic metasurface that consists of elongated apertures in 40 nm gold film, which exhibit intriguing properties such as on-and off-axis focusing and also can concentrate light into multiple, discrete spots for circularly polarized incident lights. First, the spatial transmission phase distributions of the designed metalens with arbitrary focusing can be obtained by computergenerated holography. Then, the discrete phase distributions can be continuously encoded by subwavelength nanoapertures with spatially varying orientations in gold film. The simulation results show that our designed metalens can work efficiently for different types of focusing. Finally, our metasurface shows superior broadband characteristics between 670 and 810 nm, and the corresponding focal lengths of the designed lenses also can be efficiently modulated with the incident lights at different wavelengths.Rongzhen Li Zhongyi Guo Wei Wang Jingran Zhang Keya Zhou Jianlong Liu Shiliang Qu Shutian Liu Jun Gao 2015Photonics Research2015,3,5:6
14Ultra-thin,planar,broadband,dual-polarity plasmonic metalens显示文摘An ultrathin,planar,broadband metalens composed of metal rectangular split-ring resonators(MRSRRs) has been designed,which shows dual-polarity characteristics for different types of circularly polarized(CP) light incidence.The designed metalens can be considered as the focusing lens and the diverging lens under left-handed CP and right-handed CP light incidence,respectively.The phase discontinuity of the cross-polarized transmission light is produced by optical-axis rotation through modulating two arms’ lengths of the MRSRR.The MRSRR metalens possesses a wavelength-controllable focal length and a relatively larger chromatic aberration compared with the conventional lenses.And the focal length changes from 9 to 7 μm with incident wavelength from 740 to 950 nm.The dual-polarity flat metalens opens a door for new applications of phase discontinuity devices,and it will promote the fabricating capability of on-chip or fiber-embedded optical devices.Wei Wang Zhongyi Guo Rongzhen Li Jingran Zhang Yi Liu Xinshun Wang and Shiliang Qu 2015Photonics Research2015,3,3:4
15The contribution of attached Ulva prolifera on Pyropia aquaculture rafts to green tides in the Yellow Sea显示文摘Green tides caused by the unusual accumulation of high floating Ulva prolifera have occurred regularly in the Yellow Sea since 2007.The primary source of the Yellow Sea green tides is the attached algae on the Pyropia aquaculture rafts in the Subei Shoal.Ulva prolifera and Blidingia(Italic)sp.are the main species observed on Pyropia aquaculture rafts in the Subei Shoal.We found that U.prolifera has strong buoyancy and a rapid growth rate,which may explain why it is the dominant species of green tides that occur in the China's sea area of the Yellow Sea.The growth rate of floating U.prolifera was about 20%–31%d–1,which was much higher than Blidingia(Italic)sp.There were about 1.7×104 t of attached algae on the Pyropia aquaculture rafts in May 2012.We found that 39%of attached algae could float when the tide rose in the Subei Shoal,and U.prolifera accounted for 63%of the floating algae.Our analysis estimated that about 4000 t of attached U.prolifera floated into the surrounding waters of the Subei Shoal during the recycling period of aquaculture rafts.These results suggest that the initial floating biomass of large-scale green tides in the Yellow Sea is determined by the U.prolifera biomass attached to Pyropia aquaculture rafts,further impacting the scale of the green tide。Hongbin Han Shiliang Fan Wei Song Yan Li Jie Xiao Zongling Wang Xuelei Zhang Dewen Ding 2020Acta Oceanologica Sinica2020,39,2:3
16The Distribution of Green Algal Micro-Propagules and Macroalgae at the Early Stage of Green Tide in the Coastal Area of South Jiangsu Province in 2014显示文摘An integrated investigation was carried out during late April to late May of 2014 in the coastal area of South Jiangsu Province to understand the early development of green tide in the Yellow Sea and discover the temporal and spatial distribution of green algal micro-propagules and macroalgae at the early stage of green tide. The results showed that green algal micro-propagules distributed in all stations from late April to late May, and micro-propagules of high density(> 300 ind. L^(-1)) concentrated in the adjacent Porphyra aquaculture area. Floating macroalgae were initially observed in the northern survey areas, and increased gradually. The dominant species was U. prolifera in the floating macroalgae, ranging between 90% and 100%. The seawater surface temperature and salinity in the above mentioned time period were suitable for the growth of macroalgae. This work can help government to strengthen management to reduce the blooms of macroalgae in the coastal area of South Jiangsu Province and also facilitate the decision-making for managers at the early stage of green tide.LIU Xiangqing WANG Zongling FAN Shiliang ZHANG Xuelei LI Ruixiang LI Yan 2017Journal of Ocean University of China2017,16,1:3
17Landscape Network Approach to Assess Ecological Impacts of Road Projects on Biological Conservation显示文摘Awareness of the adverse ecological effects of road and other large construction projects has resulted in a rapidly growing demand to quantitatively predict and evaluate the effects on gene flow among plants and animals in natural habitats.In this study,we evaluated the effects of different road construction scenarios on animal species movement by using the methods of ecological landscape connectivity in the typical regions of Yunnan Province,China.The results showed landscape connectivity levels(Probability of Connectivity(PC))decreased after road construction and species with lower dispersal abilities were more affected to the subsequent habitat fragmentation.First level roads affected landscape connectivity most significantly.At a distance of 100 m,the PC index decreased more than 50%.Further analysis suggested that the use of landscape connectivity to assess landscape processes revealed the adverse effects on the species movement more effectively compared with the traditional landscape pattern analysis.In addition,we conducted a graph theory and a least-cost modeling discussion,it is obvious that they are powerful tools to represent and analyze landscape networks with respect to related species movement.Network analysis offers a quantitative and simple but effective tool for ecological process assessment and biological conservation on large scales.LIU Shiliang DENG Li CHEN Liding LI Junran DONG Shikui ZHAO Haidi 2014Chinese Geographical Science2014,24,1:3
18Evidence for charge and spin density waves in single crystals of La_(3)Ni_(2)O_(7) and La_(3)Ni_(2)O_(6)显示文摘Charge and spin orders are intimately related to superconductivity in copper oxide superconductors.Elucidation of the competing orders in various nickel oxide compounds is crucial,given the fact that superconductivity has been discovered in Nd_(0.8)Sr_(0.2)NiO_(2)films.Herein,we report structural,electronic transport,magnetic,and thermodynamic characterizations of single crystals of La_(3)Ni_(2)O_(7)and La_(3)Ni_(2)O_(6).La_(3)Ni_(2)O_(7)is metallic with mixed Ni^(2+)and Ni^(3+)valent states.Resistivity measurements yield two transition-like kinks at~110 and 153 K.The kink at 153 K is further revealed from magnetization and specific heat measurements,indicative of the formation of charge and spin density waves.La_(3)Ni_(2)O_(6)single crystals obtained from the topochemical reduction of La_(3)Ni_(2)O_(7)are insulating and show an anomaly at~176 K on magnetic susceptibility.The transition-like behaviors of La_(3)Ni_(2)O_(7)and La_(3)Ni_(2)O_(6)are analogous to those observed in La_(4)Ni_(3)O_(10) and La_(4)Ni_(3)O_(8),suggesting that charge and spin density waves are a common feature in the ternary La-Ni-O system with mixed-valent states of nickel.Zengjia Liu Hualei Sun Mengwu Huo Xiaoyan Ma Yi Ji Enkui Yi Lisi Li Hui Liu Jia Yu Ziyou Zhang Zhiqiang Chen Feixiang Liang Hongliang Dong Hanjie Guo Dingyong Zhong Bing Shen Shiliang Li Meng Wang 2023Science China(Physics,Mechanics & Astronomy)2023,66,1:2
19Association of human leukocyte antigen-DR-DQ-DP haplotypes with the risk of hepatitis B virus-related hepatocellular carcinoma显示文摘Aim:Genetic polymorphisms of human leukocyte antigen(HLA)class II molecules are associated with chronic hepatitis B virus(HBV)infection.We aimed to investigate the impacts of HLA-II haplotypes on viral evolution and the risks of HBV-caused liver diseases.Methods:HLA-DR-DQ-DP haplotypes were estimated in 1210 healthy controls,296 HBV clearance subjects,301 asymptomatic hepatitis B surface antigen carriers,770 chronic hepatitis B patients,443 HBV-related liver cirrhosis(LC)patients,and 1037 HBV-related hepatocellular carcinoma(HCC)patients.HBV mutations were determined by sequencing.The associations of HLA-DR-DQ-DP haplotypes with viral mutations and the risks of liver diseases were assessed by multivariate logistic regression.Results:Compared to HBV-free subjects,the haplotypes CCAACG,CCGACG,TCAATA,and TCGATA were associated with decreased HCC risk,with an odds ratio(OR)[95%confidence interval(CI)]of 0.62(0.40-0.95),0.60(0.39-0.92),0.73(0.54-0.98),and 0.58(0.42-0.78),respectively.CCAACG,CCGACG,and TCAATA were significantly associated with decreased frequencies of the HCC-risk HBV mutations:preS1 deletion,APOBECsignature HBV mutations in the core promoter and preS regions,A51C/T,G104C/T,and G146C/T.TCGATA and TTAACG were associated with increased LC risk,with an OR(95%CI)of 1.54(1.03-2.30)and 2.23(1.50-3.33),respectively.However,TCGATA and TTAACG were not consistently associated with the cirrhosis-risk HBV mutations.Conclusion:CCAACG,CCGACG,and TCAATA are inversely associated with HCC risk,possibly because they are involved in creating an immune microenvironment attenuating the generation of HCC-risk HBV mutations.TCGATA and TTAACG might predispose the polarity of immunity towards Th17 isotype related to LC.Yifan Chen Jiansheng Lin Yang Deng Wenbin Liu Zishuai Li Xinyu Zhou Shiliang Cai Rui Pu Jianhua Yin Xiaojie Tan Jun Zhao Xue Han Guangwen Cao 2022Hepatoma Research2022,8,1:2
