| 1 | Petrogenesis of the Xihuashan Granite in Southern Jiangxi Province,South China:Constraints from Zircon U-Pb Geochronology,Geochemistry and Nd Isotopes显示文摘Mesozoic granitic intrusions are widely distributed in the Nanling region,South China.Yanshanian granites are closely connected with the formation of tungsten deposits.The Xihuashan granite is a typical representative of tungsten-bearing granite.The Xihuashan granite consists mainly of medium-grained porphyritic biotite granite,medium-grained biotite granite and fine-grained two-mica granite,which correspond to LA-ICP-MS zircon U-Pb ages of 155.5±0.4 Ma,153.0±0.6 Ma and 152.8±0.9 Ma,respectively.Rocks from the Xihuashan mining area displays high SiO2(73.85% to 76.49%) and Na2O+K2O contents(8.09% to 9.43%),belonging to high-K calc-alkaline series.They are metaluminous to weakly peraluminous with A/CNK values ranging from 0.96 to 1.06.All granites in this study area are rich in Rb,Th,U and Pb,and depleted in Ba,Sr,P,Ti,Nb and Eu,especially depleted in medium-grained biotite granite and fine-grained two-mica granite.The medium-grained porphyritic biotite granites usually have high LREE concentrations,whereas medium-grained biotite granite and fine-grained two-mica granite displays high HREE contents.Our geochemical data reveal that the studied rocks are highly fractionated I-type granite.The magma underwent strong magma differentiation with decreasing temperature and increasing oxygen fugacity,which may explain the formation of three types of distinct granites.Variations of Rb,Sr and Ba concentrations in different type granites were controlled by fractional crystallization of biotite and feldspar.Fractional crystallization of monazite,allanite and apatite resulted in LREE changes in granite,and formation of garnet mainly caused HREE changes.Granites from the Xihuashan mining area have relatively high εNd(t) values(-9.77 to -11.46),indicating that they were probably generated by partial melting of underlying Proterozoic metasedimentary rocks with minor addition of juvenile crust or mantle-derived magmas. | YANG Jiehua PENG Jiantang ZHAO Junhong FU Yazhou YANG Chen HONG Yinglong | 2012 | Acta Geologica Sinica(English Edition)2012，86，1： | 17 |
| 2 | Os isotopic compositions of a cobalt-rich ferromanganese crust profile in Central Pacific显示文摘187Os/188Os ratios in all sub-layers of the Co-rich ferromanganese crust MP5D17 from Line Seamount in Central Pacific have been systematically determined. The 187Os/188Os values in this crust are highly variable, ranging from 0.4262 to 1.0155. From the bottom to the top, the os-mium isotopic ratios of the crust display a regular variation trend, which correlates well with its changes in structure and texture in the vertical profile. In comparison with the evolu-tion curve of Os isotopic composition in seawater over the past 80 Ma, a similar evolution tendency can be found with respect to the Os isotopic composition of the crust in this study. It is preliminarily concluded that the crust MP5D17 began to grow at about 72 Ma, and underwent three growth hiatuses, corresponding to the geological ages of 64, 53 and 37 Ma, respectively. | FU Yazhou PENG Jiantang QU Wenjun HU Ruizhong SHI Xuefa DU Andao | 2005 | Chinese Science Bulletin2005，50，18： | 13 |
| 3 | A NOVEL APPROACH TO TESTING THE DYNAMIC SHEAR RESPONSE OF Ti-6Al-4V显示文摘Modifications were made on the traditional split Hopkinson pressure bar (SHPB) system to conduct dynamic shear tests. The shear response of Ti-6Al-4V was acquired at a shear strain rate of 10 4 s 1 by using this modified apparatus. The geometry as well as the clamping mode of the double-notch specimen was optimized by commercial FEM software ABAQUS, and the feasibility of the experiment set-up was validated. A shear stress calibration coefficient of τ = 1.03 and a shear strain calibration coefficient of Γ = 0.50 were obtained.We have employed high-speed photography to record the deformation process, especially the initiation and propagation of adiabatic shear band (ASB), during the dynamic shear test. The frames show that the time duration from ASB initiation to its completion is less than 2 μs, from which we can estimate that the propagation speed of ASB within Ti-6Al-4V is more than 1250 m/s under such loading conditions. The temperature rise within ASB is also estimated to be T 2 ≈ 1460℃ based on energy balance. Such high temperature has led to softening of the material within the ASBs, and has intensified the shear localization and finally resulted in fracture of the material. | Yazhou Guo Yulong Li | 2012 | Acta Mechanica Solida Sinica2012，25，3： | 12 |

| 5 | Recent developments in HVDC transmission systems to support renewable energy integration显示文摘The demands for massive renewable energy integration, passive network power supply, and global energy interconnection have all gradually increased, posing new challenges for high voltage direct current(HVDC) power transmission systems, including more complex topology and increased diversity of bipolar HVDC transmission. This study proposes that these two factors have led to new requirements for HVDC control strategies. Moreover, due to the diverse applications of HVDC transmission technology, each station in the system has different requirements. Furthermore, the topology of the AC-DC converter is being continuously developed, revealing a trend towards hybrid converter stations. | Zhou Li Ruopei Zhan Yazhou Li Yan He Jinming Hou Xiaoling Zhao Xiao-Ping Zhang | 2018 | Global Energy Interconnection2018，1，5： | 11 |
| 6 | An Approach of Distributed Joint Optimization for Cluster-based Wireless Sensor Networks显示文摘Wireless sensor networks(WSNs) are energyconstrained,so energy saving is one of the most important issues in typical applications.The clustered WSN topology is considered in this paper.To achieve the balance of energy consumption and utility of network resources,we explicitly model and factor the effect of power and rate.A novel joint optimization model is proposed with the protection for cluster head.By the mean of a choice of two appropriate sub-utility functions,the distributed iterative algorithm is obtained.The convergence of the proposed iterative algorithm is proved analytically.We consider general dual decomposition method to realize variable separation and distributed computation,which is practical in large-scale sensor networks.Numerical results show that the proposed joint optimal algorithm converges to the optimal power allocation and rate transmission,and validate the performance in terms of prolonging of network lifetime and improvement of throughput. | Zhixin Liu Yazhou Yuan Xinping Guan Xinbin Li | 2015 | IEEE/CAA Journal of Automatica Sinica2015，2，3： | 10 |
| 7 | Discovery and Significance of Diamonds and Moissanites in Chromitite within the Skenderbeu Massif of the Mirdita Zone Ophiolite,West Albania显示文摘In recent years diamonds and other unusual minerals(carbides,nitrides,metal alloys and native elements) have been recovered from mantle peridotites and chromitites(both high-Cr chromitites and high-Al chromitites) from a number of ophiolites of different ages and tectonic settings.Here we report a similar assemblage of minerals from the Skenderbeu massif of the Mirdita zone ophiolite,west Albania.So far,more than 20 grains of microdiamonds and 30 grains of moissanites(SiC) have been separated from the podiform chromitite.The diamonds are mostly light yellow,transparent,euhedral crystals,200~300 μm across,with a range of morphologies;some are octahedral and cuboctahedron and others are elongate and irregular.Secondary electron images show that some grains have well-developed striatums.All the diamond grains have been analyzed and yielded typical Raman spectra with a shift at ~1325 cm^(-1).The moissanite grains recovered from the Skenderbeu chromitites are mainly light blue to dark blue,but some are yellow to light yeUow.All the analyzed grains have typical Raman spectra with shifts at 766 cm^(-1),787 cm^(-1),and 967 cm^(-1).The energy spectrums of the moissanites confirm that the grains are composed entirely of silicon and carbon.This investigation expands the occurrence of diamonds and moissanites to Mesozoic ophiolites in the Neo-Tethys.Our new findings suggest that diamonds and moissanites are present,and probably ubiquitous in the oceanic mantle and can provide new perspectives and avenues for research on the origin of ophiolites and podiform chromitites. | WU Weiwei YANG Jingsui MA Changqian MILUSHI Ibrahim LIAN Dongyang TIAN Yazhou | 2017 | Acta Geologica Sinica(English Edition)2017，91，3： | 10 |
| 8 | Diamond Discovered in High-Al Chromitites of the Sartohay Ophiolite,Xinjiang Province,China显示文摘In recent years diamonds and other exotic minerals have been recovered from mantle peridotites and high-Cr chromitites of a number of ophiolites of different age and different tectonic environments. Here we report a similar collection of minerals from the Sartohay ophiolite of Xinjiang Province,western China,which is characterized by having high-Al chromitites. Several samples of massive podiform chromitite with an aggregate weight of nearly 900 kg yielded diamonds,moissanite and other highly reduced minerals,as well as common crustal minerals. Thus far,more than 20 grains each of diamond and moissanite have been recovered from heavy mineral separates of the chromitites. The diamonds are all 100-200 μm in size and range in color from pale yellow to reddish-orange to colorless. Most of the grains are anhedral to subhedral octahedra,commonly with elongate forms exhibiting well-developed striations. They all display characteristic Raman spectra with shifts between 1325 cm-1 and 1333 cm-1,mostly 1331.51 cm-1 or 1326.96 cm-1. The moissanite grains are light blue to dark blue,broken crystals,50-150 μm across,commonly occurring as small flakes or fragments. Their typical Raman spectra have shifts at 762 cm-1,785 cm-1,and 966 cm-1. This investigation extends the occurrence of diamonds and moissanite to a Paleozoic ophiolite in the Central Asian Orogenic Belt and demonstrates that these minerals can also occur in high-Al chromitites. We conclude that diamonds and moissanite are likely to be ubiquitous in ophiolitic mantle peridotites and chromitites. | TIAN Yazhou YANG Jingsui Paul T.ROBINSON XIONG Fahui LI Yuan ZHANG Zhongming LIU Zhao LIU Fei NIU Xiaolu | 2015 | Acta Geologica Sinica(English Edition)2015，89，2： | 9 |
| 9 | Symmetry and nonexistence of positive solutions to an integral system with weighted functions显示文摘Consider the system of integral equations with weighted functions in Rn,{u(x) =∫Rn|x-y|α-nQ(y)v(y)qdy1,v(x)=∫Rn|x-y|α-nK(y)u(y)pdy,where 0 < α < n,1/(p+1) + 1/(q+1)≥(n-α)/n1,α/(n-α) < p1q < ∞1,Q(x) and K(x) satisfy some suitable conditions.It is shown that every positive regular solution(u(x)1,v(x)) is symmetric about some plane by developing the moving plane method in an integral form.Moreover,regularity of the solution is studied.Finally,the nonexistence of positive solutions to the system in the case 0 < p1q <(n+α)/(n-α) is also discussed. | DOU JingBo QU ChangZheng HAN YaZhou | 2011 | Science China Mathematics2011，54，4： | 8 |
| 10 | Definition of the general initial water penetration fracture criterion for concrete and its engineering application显示文摘A general initial water penetration(seepage) fracture criterion for concrete is proposed to predict whether or not harmful water penetration(hydraulic fracturing),other than microcracking,will occur in concrete structures in a severe high water pressure environment.The final regression,of the different macroscopic failure types in concrete to microscopic ModeⅠ c racking,allows the use of only one universal criterion to indicate the damage.Thus,a general initial water penetration fracture criterion is approximately defined as a strain magnitude of 1000×10-6,based on the concept of tensile strain derived from experimental results in the relevant literature.Then,the locations of harmful water penetration fracture(hydraulic fracture) in the high arch dam mass of the Jinping first class hydropower project are analyzed using the nonlinear finite element method(FEM) according to the proposed criterion.The proposed criterion also holds promise for other concrete structures in high water pressure environments. | JIANG YaZhou REN QingWen XU Wei LIU Shuang | 2011 | Science China(Technological Sciences)2011，54，6： | 6 |
| 11 | Protein Phosphorylation and Phosphoproteome:An Overview of Rice显示文摘Protein phosphorylation,one of the major post-translational modifications,plays a crucial role in cell signaling,DNA replication,gene expression and differentiation;and alters enzyme activity and other biological activities;and regulates cell proliferation and enlargement,phytohormone biosynthesis and signaling,plant disease resistance,and grain filling and quality during rice seed development.Research work on protein phosphorylation started in the 1950 s with the discovery of phosphorylase a and phosphorylase b which are phospho and dephospho forms of the same enzyme.Over the last decade,rice proteomics has accomplished tremendous progress in setting up techniques to proteome nearly all tissues,organs and organelles.The progress made in this field is evident in number of research works.However,research on rice protein phosphorylation is still at its infancy and there are still many unanswered questions.In this review,the general description of protein phosphorylation,including history,structure,frequency of occurrence and function,are discussed.This work also elucidates the different methods for identification,qualification and finally,the progress in rice phosphoproteome research and perspectives. | Abolore Adijat AJADI Amara CISSE Shakeel AHMAD WANG Yifeng SHU Yazhou LI Shufan LIU Xixi Babatunde Kazeem BELLO Sani Muhammad TAJO TONG Xiaohong ZHANG Jian | 2020 | Rice science2020，27，3： | 5 |
| 12 | Design and physical model experiment of an attitude adjustment device for a crawler tractor in hilly and mountainous regions显示文摘To address the problems of difficult leveling and poor stability of hill crawler tractors,an attitude adjustment device based on a parallel four-bar mechanism was designed,and the mechanical reasons for the sideslip instability of hill crawler tractors were analyzed.On this basis,a posture adjustment mechanism based on a parallel four-bar mechanism was proposed,and the structure of the complete attitude adjustment device was designed.To ensure that this device meets the strength requirements during operation,a mechanical analysis of the key components(active rocker and slave rocker)was carried out to accommodate the load during leveling.Based on ANSYS software,a finite element simulation analysis was used to determine the maximum stress position of the active and slave rockers.Finally,to verify the accuracy of the above simulation analysis results and determine the influence rules of the lateral slope angle,longitudinal slope angle and loading quality on the abovementioned maximum stress,a physical model test bench of the attitude adjustment device was built.An orthogonal regression experiment was carried out with the maximum stresses of the active and slave rockers as the test indices.The experimental data were analyzed by Design-Expert 10 software,and the results show that the order of the primary and secondary factors influencing the maximum stress of the active rocker was the loading mass,lateral slope angle and longitudinal slope angle.The order of the factors influencing the maximum stress of the slave rocker was the longitudinal slope angle,lateral slope angle and loading mass.The active and slave rockers meet the strength requirements.This work provides technical support for the production of hill crawler tractor physical prototypes. | Jingbin Sun Chong Meng Yazhou Zhang Guoping Chu Yanjie Zhang Fuzeng Yang Zhijie Liu | 2020 | Information Processing in Agriculture2020，7，3： | 5 |
| 13 | Kelly sideband suppression and wavelength tuning of a conventional soliton in a Tm-doped hybrid mode-locked fiber laser with an all-fiber Lyot filter显示文摘We demonstrate a stable conventional soliton in a Tm-doped hybrid mode-locked fiber laser by employing a homemade all-fiber Lyot filter(AFLF) and a single-wall carbon nanotube. The AFLF, designed by sandwiching a piece of polarization-maintained fiber(PMF) with two 45° tilted fiber gratings inscribed by a UV laser in PMF with a phase-mask scanning technique, shows large filter depth of ~9 d B and small insertion loss of ~0.8 dB. By optimizing the free spectral range of the AFLF, the Kelly sidebands of a conventional soliton centered at1966.4 nm can be dramatically suppressed without impairing the main shape of the soliton spectrum. It gives the pulse duration of 1.18 ps and bandwidth of 3.8 nm. By adjusting the temperature of the PMF of the AFLF from 7°C to 60°C, wavelength tunable soliton pulses ranging from 1971.62 nm to 1952.63 nm are also obtained.The generated soliton pulses can be precisely tuned between 1971.62 nm and 1952.63 nm by controlling the temperature of the AFLF. | JIANFENG LI YAZHOU WANG HONGYU LUO YONG LIU ZHIJUN YAN ZHONGYUAN SUN LIN ZHANG | 2019 | Photonics Research2019，7，2： | 5 |
| 14 | The OsNAC23-Tre6P-SnRK1 a feed-forward loop regulates sugar homeostasis and grain yield in rice显示文摘Tre6P(trehalose-6-phosphate)mediates sensing of carbon availability to maintain sugar homeostasis in plants,which underpins crop yield and resilience.However,how Tre6P responds to fluctuations in sugar levels and regulates the utilization of sugars for growth remains to be addressed.Here,we report that the sugar-inducible rice NAC transcription factor OsNAC23 directly represses the transcription of the Tre6P phosphatase gene TPP1 to simultaneously elevate Tre6P and repress trehalose levels,thus facilitating carbon partitioning from source to sink organs.Meanwhile,OsNAC23 and Tre6P suppress the transcription and enzyme activity of SnRK1a,a low-carbon sensor and antagonist of OsNAC23,to prevent the SnRK1a-mediated phosphorylation and degradation of OsNAC23.Thus,OsNAC23,Tre6P,and SnRK1a form a feed-forward loop to sense sugar and maintain sugar homeostasis by transporting sugars to sink organs.Importantly,plants over-expressing OsNAC23 exhibited an elevated photosynthetic rate,sugar transport,and sink organ size,which consistently increased rice yields by 13%–17%in three elite-variety backgrounds and two locations,suggesting that manipulation of OsNAC23 expression has great potential for rice improvement.Collectively,these findings enhance our understanding of Tre6P-mediated sugar signaling and homeostasis,and provide a new strategy for genetic improvement of rice and possibly also other crops. | Zhiyong Li Xiangjin Wei Xiaohong Tong Juan Zhao Xixi Liu Huimei Wang Liqun Tang Yazhou Shu Guanghao Li Yifeng Wang Jiezheng Ying Guiai Jiao Honghong Hu Peisong Hu Jian Zhang | 2022 | Molecular Plant2022，15，4： | 4 |
| 15 | Ultimate bearing capacity of concrete dam involved in geometric and material nonlinearity显示文摘To get the actual ultimate bearing capacity of concrete dam, the effect of geometric nonlinearity and strain softening on it, which appears in the failure process of concrete dam, is studied. Overload method is adopted to obtain the bearing capacity of a concrete dam by taking into consideration strain softening in the material constitutive law, geometric nonlinearity in geometric equation and equilibrium differential equation. Arc-length method is used to find the extreme point and descending branch of the load-displacement curve of the dam. The results present that the effect cannot be ignored. And geometric nonlinearity of structure and strain softening of materials should be considered for numerical analysis of ultimate bearing capacity of a concrete dam. | REN QingWen JIANG YaZhou | 2011 | Science China(Technological Sciences)2011，54，3： | 4 |
| 16 | Inhibition of in-stent restenosis after graphene oxide double-layer drug coating with good biocompatibility显示文摘In this study,we designed a double layer-coated vascular stent of 316L stainless steel using an ultrasonic spray system to achieve both antiproliferation and antithrombosis.The coating included an inner layer of graphene oxide(GO)loaded with docetaxel(DTX)and an outer layer of carboxymethyl chitosan(CMC)loaded with heparin(Hep).The coated surface was uniform without aggregation and shedding phenomena before and after stent expanded.The coating treatment was able to inhibit the adhesion and activation of platelets and the proliferation and migration of smooth muscle cells,indicating the excellent biocompatibility and antiproliferation ability.The toxicity tests showed that the GO/DTX and CMC/Hep coating did not cause deformity and organ abnormalities in zebrafish under stereomicroscope.The stents with GO double-layer coating were safe and could effectively prevent thrombosis and in-stent restenosis after the implantation into rabbit carotid arteries for 4–12 weeks. | Shuang Ge Yadong Xi Ruolin Du Yuzhen Ren Zichen Xu Youhua Tan Yazhou Wang Tieying Yin Guixue Wang | 2019 | Regenerative Biomaterials2019，6，5： | 4 |
| 17 | Noble metal-free catalysts for oxygen reduction reaction显示文摘Developing noble metal-free catalysts with low cost, high performance and stability for oxygen reduction reaction(ORR) in fuel cells is of great interest to promote sustainable energy devices. In this review, we summarized noble metal-free catalysts for ORR,including non-noble metal-based and heteroatom-doped carbon nanomaterials. Mesoporous structure, homogeneous distribution of nanocrystals and synergistic effect of carbon base and nanocrystals/doped heteroatoms have great effect on the ORR property.The noble metal-free nanomaterials showed comparable catalytic property, better stability and methanol tolerance than commercial platinum(Pt)-based catalysts, showing great potential as substitutes for noble metal-based catalysts. In addition, the challenges and chances of developing noble metal-free ORR catalysts are also discussed. | Xiaoxiao Huang Yazhou Wang Wei Li Yanglong Hou | 2017 | Science China Chemistry2017，60，12： | 4 |
| 18 | Different surface modification methods and coating materials of zinc metal anode显示文摘Rechargeable aqueous Zn-ion batteries(AZIBs)are one of the most promising energy storage devices for large-scale energy storage owing to their high specific capacity,eco-friendliness,low cost and high safety.Nevertheless,zinc metal anodes suffer from severe dendrite growth and side reactions,resulting in the inferior electrochemical performance of AZIBs.To address these problems,surface modification of zinc metal anodes is a facile and effective method to regulate the interaction between the zinc anode and an electrolyte.In this review,the current challenges and strategies for zinc metal anodes are presented.Furthermore,recent advances in surface modification strategies to improve their electrochemical performance are concluded and discussed.Finally,challenges and prospects for future development of zinc metal anodes are proposed.We hope this review will be useful for designing and fabricating highperformance AZIBs and boosting their practical applications. | Feng Tao Yong Liu Xinyuan Ren Jing Wang Yazhou Zhou Yingjie Miao Fengzhang Ren Shizhong Wei Jianmin Ma | 2022 | Journal of Energy Chemistry2022，31，3： | 4 |
| 19 | Modelling of the In uence of Tool Runout on Surface Generation in Micro Milling显示文摘Micro milling is a flexible and economical method to fabricate micro components with three-dimensional geometry features over a wide range of engineering materials. But the surface roughness and micro topography always limit the performance of the machined micro components. This paper presents a surface generation simulation in micro end milling considering both axial and radial tool runout. Firstly, a surface generation model is established based on the geometry of micro milling cutter. Secondly, the influence of the runout in axial and radial directions on the surface generation are investigated and the surface roughness prediction is realized. It is found that the axial runout has a significant influence on the surface topography generation. Furthermore, the influence of axial runout on the surface micro topography was studied quantitatively, and a critical axial runout is given for variable feed per tooth to generate specific surface topography. Finally, the proposed model is validated by means of experiments and a good correlation is obtained. The proposed surface generation model o ers a basis for designing and optimizing surface parameters of functional machined surfaces. | Wanqun Chen Yazhou Sun Dehong Huo Xiangyu Teng | 2019 | Chinese Journal of Mechanical Engineering2019，32，1： | 3 |
