| 1 | Nuclear phylotranscriptomics and phylogenomics support numerous polyploidization events and hypotheses for the evolution of rhizobial nitrogenfixing symbiosis in Fabaceae显示文摘Fabaceae are the third largest angiosperm family,with 765 genera and~19500 species.They are important both economically and ecologically,and global Fabaceae crops are intensively studied in part for their nitrogen-fixing ability.However,resolution of the intrasubfamilial Fabaceae phylogeny and divergence times has remained elusive,precluding a reconstruction of the evolutionary history of symbiotic nitrogen fixation in Fabaceae.Here,we report a highly resolved phylogeny using>1500 nuclear genes from newly sequenced transcriptomes and genomes of 391 species,along with other datasets,for a total of 463 legumes spanning all 6 subfamilies and 333 of 765 genera.The subfamilies are maximally supported as mono-phyletic.The clade comprising subfamilies Cercidoideae and Detarioideae is sister to the remaining legumes,and Duparquetioideae and Dialioideae are successive sisters to the clade of Papilionoideae and Caesalpinioideae.Molecular clock estimation revealed an early radiation of subfamilies near the K/Pg boundary,marked by mass extinction,and subsequent divergence of most tribe-level clades within~15 million years.Phylogenomic analyses of thousands of gene families support 28 proposed putative whole-genome duplication/whole-genome triplication events across Fabaceae,including those at the ancestors of Fabaceae and five of the subfamilies,and further analyses supported the Fabaceae ancestral polyploidy.The evolution of rhizobial nitrogen-fixing nodulation in Fabaceae was probed by ancestral character reconstruction and phylogenetic analyses of related gene families and the results support the hypotheses of one or two switches)to rhizobial nodulation followed by multiple losses.Collectively,these results provide a foundation for further morphological and functional evolutionary analyses across Fabaceae. | Yiyong Zhao Rong Zhang Kai-Wen Jiang Ji Qi Yi Hu Jing Guo Renbin Zhu Taikui Zhang Ashley N.Egan Ting-Shuang Yi Chien-Hsun Huang Hong Ma | 2021 | Molecular Plant2021，14，5： | 8 |
| 2 | The application of nanostructured transition metal sulfides as anodes for lithium ion batteries显示文摘With wide application of electric vehicles and large-scale in energy storage systems, the requirement of secondary batteries with higher power density and better safety gets urgent. Owing to the merits of high theoretical capacity, relatively low cost and suitable discharge voltage, much attention has been paid to the transition metal sulfides. Recently, a large amount of research papers have reported about the application of transition metal sulfides in lithium ion batteries. However, the practical application of transition metal sulfides is still impeded by their fast capacity fading and poor rate performance. More well-focused researches should be operated towards the commercialization of transition metal sulfides in lithium ion batteries. In this review, recent development of using transition metal sulfides such as copper sulfides,molybdenum sulfides, cobalt sulfides, and iron sulfides as electrode materials for lithium ion batteries is presented. In addition, the electrochemical reaction mechanisms and synthetic strategy of transition metal sulfides are briefly summarized. The critical issues, challenges, and perspectives providing a further understanding of the associated electrochemical processes are also discussed. | Jinbao Zhao Yiyong Zhang Yunhui Wang He Li Yueying Peng | 2018 | Journal of Energy Chemistry2018，27，6： | 7 |
| 3 | Constrained adaptive neural network control of an MIMO aeroelastic system with input nonlinearities显示文摘A constrained adaptive neural network control scheme is proposed for a multi-input and multi-output(MIMO) aeroelastic system in the presence of wind gust,system uncertainties,and input nonlinearities consisting of input saturation and dead-zone.In regard to the input nonlinearities,the right inverse function block of the dead-zone is added before the input nonlinearities,which simplifies the input nonlinearities into an equivalent input saturation.To deal with the equivalent input saturation,an auxiliary error system is designed to compensate for the impact of the input saturation.Meanwhile,uncertainties in pitch stiffness,plunge stiffness,and pitch damping are all considered,and radial basis function neural networks(RBFNNs) are applied to approximate the system uncertainties.In combination with the designed auxiliary error system and the backstepping control technique,a constrained adaptive neural network controller is designed,and it is proven that all the signals in the closed-loop system are semi-globally uniformly bounded via the Lyapunov stability analysis method.Finally,extensive digital simulation results demonstrate the effectiveness of the proposed control scheme towards flutter suppression in spite of the integrated effects of wind gust,system uncertainties,and input nonlinearities. | Gou Yiyong Li Hongbo Dong Xinmin Liu Zongcheng | 2017 | Chinese Journal of Aeronautics2017，30，2： | 7 |
| 4 | Phylotranscriptomics in Cucurbitaceae Reveal Multiple Whole-Genome Duplications and Key Morphological and Molecular Innovations显示文摘The ability of climbing plants to grow upward along others to reach the canopy for photosynthesis is hypothesized as a key innovation in flowering plants.Most members of the Cucurbitaceae,a family containing^1000 species and many important crops,are climbers and have characteristic tendrils and pepo fruits.Here,we present 127 newly sequenced transcdptomes and genomes along with other datasets for a total of 136 cucurbits representing all tribes to establish a robust Cucurbitaceae phylogeny containing eight highly resolved major clades.We analyzed whole-genome duplication,diversification dynamics,and ancestral morphologies,and found that after early genome duplication event(s),a burst of diversification and morphological innovations in flower,fruit,and root characters occurred under the climate optimum in the Early Eocene.Species radiation during the Mid-Eocene Climatic Optimum also coincided with several morphological changes shared by 80%of cucurbits.We found that the cucurbit-specific tendril identity gene TEN originated from a paleo-polyploidization event at the origin of the family.Our results support the hypothesis that cucurbit diversifications were probably driven by increased genetic diversity following polyploidizations and by trait morphological innovations under paleo-climate upheavals.Our study provides a phylogenetic framework and new insights into morphological and genomic changes underlying the adaptive evolution of Cucurbitaceae. | Jing Guo Weibin Xu Yi Hu Jie Huang Yiyong Zhao Lin Zhang Chien-Hsun Huang Hong Ma | 2020 | Molecular Plant2020，13，8： | 7 |
| 5 | Core-shell nanostructure of single-wall carbon nanotubes and covalent organic frameworks for supercapacitors显示文摘Covalent organic frameworks(COFs) were nano-coated onto single-walled carbon nanotubes(SWCNTs)by in situ polymerization of TpPa-COFs together with SWCNTs under solvothermal conditions. At the molecular level, the COF/SWCNT interface can be efficiently controlled. Thus, the TpPa-COF-SWCNTs nano-hybrid wire, which combines the excellent conductivity of SWCNTs and the high porosity and good redox activity of TpPa-COFs, was employed as active electrode materials for supercapacitors. The strategy reported in this work can give guidance for the design of other similar COF-based electrodes, and hold a great potential in energy | Yang Han Qin Zhang Nantao Hu Xue Zhang Yiyong Mai Jiaqiang Liu Xiaolin Hua Hao Wei | 2017 | Chinese Chemical Letters2017，28，12： | 5 |
| 6 | Contributions of phosphatase and microbial activity to internal phosphorus loading and their relation to lake eutrophication显示文摘Phosphatase may accelerate the process of lake eutrophication through improving phosphorus bioavailability. This mechanism was studied in three Chinese eutrophic shallow lakes (Lake Taihu, Lake Longyang and Lake Lianhua). Phosphatase activity was related to the concentration of soluble reactive phosphorus (SRP) and chlorophyll a. Stability of dissolved phosphatase in reverse micelles may be attributed to molecular size, conformation and active residues of the enzyme.At the site with Microcystis bloomed in Lake Taihu, dissolved phosphatase activity was higher and more stable in micelles, SRP concentrations were lower in interstitial water, the contents of different forms of phosphorus and the amounts of aerobic bacteria were lower while respiration efficiency was higher in sediments. Phosphobacteria, both inorganic and organic and other microorganisms were abundant in surface water but rare in sediments. Therefore, internal phosphorus may substantially flux into water column by enzymatic hydrolysis and anaerobic release, together with mobility of bacteria,thereby initiating the bloom. In short, biological mechanism may act in concert with physical and chemical factors to drive the internal phosphorus release and accelerate lake eutrophication. | SONG Chunlei, CAO Xiuyun, LI Jianqiu, LI Qingman, CHEN Guoyuan & ZHOU Yiyong Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China Graduate School of the Chinese Academy of Sciences, Beijing 100039, China | 2006 | Science China Earth Sciences2006，49，z1： | 5 |
| 7 | Interior corner flow theory and its application to the satellite propellant management device design显示文摘The interior corner flow theory is fundamental for liquid management in space. In this paper, the interior corner flow theory is modified by correction of the curvature and shape parameters based on geometry relationship, so that it can be extended to a wide range of applications including different dihedral angles and contact angles. This modification is validated with the data provided by the references using capillary tube and drop tower. Besides, the errors between the theory and experiment value are analyzed for the case of small viscosity and the long-time flow, finding that the main reason causing the error is the transformation of the flow resistance along the flow path. At last, the theory of interior corner flow is applied to the primary design of the Propellant Management Device in satellite tank, and optimum design of the vanes is given in terms of maximum flow rate. | WEI YueXing CHEN XiaoQian HUANG YiYong | 2011 | Science China(Technological Sciences)2011，54，7： | 4 |
| 8 | The Sources and Transport Patterns of Modern Sediments in Hangzhou Bay: Evidence from Clay Minerals显示文摘Clay mineral compositions of 199 offshore surface sediment samples collected from the Hangzhou Bay have been analyzed. The clay minerals in the sediments from the Hangzhou Bay are dominated by illite(58.7%, on average), followed by chlorite(20.3%), kaolinite(16.9%) and smectite(4.1%). Two provinces were classified by Q-mode cluster analysis. Class Ⅰ with relatively low amounts of illite and smectite is widely distributed in the Hangzhou Bay, especially concentrated in the top and mouth of the bay, and the northern and southern nearshore areas. Class Ⅱ with comparatively high amounts of illite and smectite is mainly concentrated in the central part of the bay with the water depth of 8–10 m. By comparing clay mineral compositions with the neighbouring regions, we can find that the sediments in the Hangzhou Bay are mainly influenced by the resuspension and repeated deposition of particles from the Yangtze River due to the strong dynamic environment. In particular, the clay fraction of Class Ⅰ is mainly supplied by the Yangtze River, while the sediments of Class Ⅱ are mixture of the clay minerals carried by the Yangtze River and Qiantang River. In general, the distributions of clay minerals in the northern bay are affected by Yangtze River runoff, coastal current and flood tide together, and in the southern they are mainly affected by the Qiantang River runoff and ebb tide. | LIU Jinqing CAO Ke YIN Ping GAO Fei CHEN Xiaoying ZHANG Yong YU Yiyong | 2018 | Journal of Ocean University of China2018，17，6： | 4 |
| 9 | Preparation of microbial desulfurization catalysts显示文摘A Rhodococcus sp. lawq, a bacterium isolated from the soil cleaving the C-S bond of dibenzothiophene (DBT) via specific pathway, was investigated for cell growth and for its role in desulfurization. Clearly, the end product, 2-hydroxybiphenyl, inhibited the growth of the strain, the synthesis of the desulfurization enzymes, and the activity of the enzymes. The effects of sulfate on the DBT degradation enzymes were examined in the Rhodococcus sp. lawq growth system with DBT; the sulfate served, concurrently, as the sulfur source. The condition of the resting cells that were used in desulfurization, was also studied. The optimal concentration of the resting cells and the reaction conditions were determined. It was documented that there is no difference between desulfurization activity for resting cells cultured with sulfate as the sole sulfur source and that with the mixture of DBT and sulfate as the sulfur source. | XU Ping MA Cuiqing LI Fuli TONG Mingyou ZENG Yiyong WANG Shuning H.D.Blankespoor | 2002 | Chinese Science Bulletin2002，47，13： | 4 |
| 10 | An Experimental Investigation on Low Load Combustion Stability and Cold-Firing Capacity of a Gasoline Compression Ignition Engine显示文摘Gasoline compression ignition (GCI) is one of the most promising combustion concepts to maintain low pollutant emissions and high efficiency. However, low load combustion stability and firing in cold-start operations are two major challenges for GCI combustion. Strategies including negative valve overlap (NVO), advanced injection strategies, fuel reforming, and intake preheating have been proposed in order to solve these difficulties;however, the cold start is still an obstacle. The objective of this work is to study effective methods to achieve GCI engine cold start-up. This work combines NVO, in-cylinder fuel reforming, and intake preheating to achieve quick firing under cold-start conditions and the subsequent warmup conditions. The results show that start of injection (SOI) during the intake stroke yields the best fuel economy, and injection during the compression stroke has the potential to extend the low load limit. Furthermore, SOI during the NVO period grants the ability to operate under engine conditions with cold intake air and coolant. With highly reactive products made by in-cylinder fuel reforming and fast heat accumulation in the combustion chamber, the NVO injection strategy is highly appropriate for GCI firing. An additional assisted technical method, such as intake preheating, is required to ignite the first firing cycle for a cold-start process. With the combination of NVO, in-cylinder fuel reforming, and intake preheating, the GCI engine successfully started within five combustion cycles in the experiment. After the firing process, the engine could stably operate without further intake preheating;thus, this method is appropriate for engine cold-start and warm-up. | Lei Zhou Jianxiong Hua Haiqiao Wei Yiyong Han | 2019 | Engineering2019，5，3： | 4 |
| 11 | Non-thermal plasma treatment of Radix aconiti wastewater generated by traditional Chinese medicine processing显示文摘The wastewater effluent from Radix aconiti processing, an important step in the production processes of traditional Chinese medicine(TCM), is a type of toxic wastewater and difficult to treat. Plasma oxidation methods have emerged as feasible techniques for effective decomposition of toxic organic pollutants. This study examined the performance of a plasma reactor operated in a dielectric barrier discharge(DBD) to degrade the effluent from R. aconiti processing. The effects of treatment time, discharge voltage, initial p H value and the feeding gas for the reactor on the degradation of this TCM wastewater were investigated. A bacterium bioluminescence assay was adopted in this study to test the toxicity of the TCM wastewater after non-thermal plasma treatment. The degradation ratio of the main toxic component was 87.77% after 60 min treatment with oxygen used as feed gas and it was 99.59% when the initial p H value was 8.0. High discharge voltage and alkaline solution environment were beneficial for improving the degradation ratio. The treatment process was found to be capable of reducing the toxicity of the wastewater to a low level or even render it non-toxic. These experimental results suggested that the DBD plasma method may be a competitive technology for primary decomposition of biologically undegradable toxic organic pollutants in TCM wastewater. | Yiyong Wen Jianping Yi Shen Zhao Song Jiang Yuming Chi Kefu Liu | 2016 | Journal of Environmental Sciences2016，28，6： | 4 |
| 12 | Analysis and design of parameters in soft docking of micro/small satellites显示文摘Although substantial research has been conducted on the soft docking problem, the design of the docking mechanism is always conducted using experience. The challenge for conducting factor analysis and design lies in an accurate theoretical model, and the evaluation criteria of a successful docking. In this paper,the soft docking model of micro/small satellites is proposed using an analytical method and validated using a commercial FE package. The evaluation criterion of a successful docking is defined by considering the operational principle of the capturing mechanism used in micro(or small) paired satellites. The effect of the parameters on the soft docking result is discussed and their value domains are designed based on our proposed criteria of a successful docking. | Xiang ZHANG Yiyong HUANG Xiaoqian CHEN | 2017 | Science China(Information Sciences)2017，60，5： | 4 |
| 13 | Objective Evaluation Method of Steering Comfort Based on Movement Quality Evaluation of Driver Steering Maneuver显示文摘The existing research of steering comfort mainly focuses on the subjective evaluation,aiming at designing and optimizing the steering system.In the development of steering system,especially the evaluation of steering comfort,the objective evaluation methods considered the kinematic characteristics of driver steering maneuver are not proposed,which means that the objective evaluation of steering cannot be conducted with the evaluation of kinematic characteristics of driver in steering maneuver.In order to propose the objective evaluation methods of steering comfort,the evaluation of steering movement quality of driver is developed on the basis of the study of the kinematic characteristics of steering maneuver.First,the steering motion trajectories of the driver in both comfortable and certain extreme uncomfortable operation conditions are detected using the Vicon motion capture system.The operation conditions are under the restrictions of the vertical height and horizontal distance between steering wheel center and the H-point of driver,and the steering resisting torque else.Next,the movement quality evaluation of driver steering maneuver is assessed using twelve kinds of evaluation indices based on the kinematic analyses of the steering motion trajectories to propose an objective evaluation method.Finally,an integrated discomfort index of steering maneuver is proposed on the basis of the regression analysis of subjective evaluation rating and the movement quality evaluation indices,including the Jerk,Discomfort and Joint Torque indices.The test results show that the proposed integrated discomfort index gives a good fitting with the subjective evaluation of discomfort,which means it can be used to evaluate or predict the discomfort level of steering maneuver.This paper proposes an objective evaluation method of steering comfort based on the movement quality evaluation of driver steering maneuver. | YANG Yiyong LIU Yahui WANG Man JI Run JI Xuewu | 2014 | Chinese Journal of Mechanical Engineering2014，27，5： | 3 |
| 14 | Optimization of Callus Induction Conditions from Immature Embryos in Maize and Plant Regeneration显示文摘This research uses the immature embryos of inbred maize lines(GSH9901,Hi01,Hi02,and Chang 7-2)as receptor materials to establish the callus induction system.These inbred lines provide the receptor materials for the genetic regeneration of maize and the verification of the genetic functions of maize.The factor experiment and orthogonal experiments were used to investigate the impacts of different genotypes,immature embryo size,shield orientation,2,4-D concentration,proline concentration,and folic acid concentration on the induction rate of embryogenic callus tissue.A sensitivity experiment testing glyphosate(Bar)and an antibiotic(Cefotaxime sodium)were also conducted.The results indicate that the immature embryos of inbred maize line GSH9901 were the most effective for callus tissue induction,and the immature embryos with a length of 1.6-2.0 mm produce the best result.The upward shield face is more successful for the formation of induced callus.Using orthogonal analysis,we found that the optimal combination for the induction system was A_(3)(2,4-D concentration 0.25 mg mL^(-1)),B_(1)C_(3)(proline concentration 0.8 mg mL^(-1)),and D 2(folate Concentration 0.5 mg mL^(-1))and the induction rate reached 84%.We found that cold storage at 4℃ for 1 d is more conducive for the formation of embryogenic callus than the other treatments tested.The sensitivity experiment for callus tissue screening revealed the critical concentration of glyphosate to be 10 mg ml^(-1),and the critical concentration of antibiotic is 250 mg ml^(-1).Using this combination of glyphosate and antibiotic resulted in regenerated plants.This study established the optimal conditions for immature embryo callus tissue induction in maize. | Peng Jiao Ruiqi Ma Zhuo Qi Zhenzhong Jiang Siyan Liu Jing Qu Shuyan Guan Yiyong Ma | 2020 | Phyton-International Journal of Experimental Botany2020，89，1： | 3 |
| 15 | Neogene palynological assemblages in the west slope of Songliao Basin and their geological implications显示文摘Abundant palynological fossils are found from the drill core in the west slope of Songliao Basin, the first full coring borehole that drilled throughout the Neogene. Two Palynological assemblages are recognized according to their vertical distributions, i.e., the late early Miocene–middle Miocene assemblage from the Da'an Formation named as Caryapollenites simplex-Momipites coryloides-Celtispollenites sp.-Tsugaepollenites igniculus, and the late Miocene-early Pliocene assemblage from the Taikang Formation named as Artemisiaepollenites minor-Betulaceoipollenites sp.-Carpinipites sp.-Polypodiaceaesporites sp. On the basis of the composition of each assemblage, we infer that the climate was warm-temperate to sub-tropic during the late early Miocene–middle Miocene and the vegetation was mainly deciduous broadleaved forest and subordinate coniferous and broad-leaved mixed forest with few understory ferns, and probably some shallow fresh water wetlands. The climate then turned cooler and drier in the late Miocene–early Pliocene, represented by the development of xerophytic herbs and temperate plants, although the canopy of the forest remained relatively stable. The results significantly improve the understanding of the Cenozoic palynostratigraphy in the Songliao Basin, and provide new data for both stratigraphical correlation and paleovegetational and paleoclimatical analysis in adjacent area. | WAN ChuanBiao SUN YueWu XUE YunFei QIAO XiuYun JIN YuDong ZHANG YiYong | 2014 | Science China Earth Sciences2014，57，10： | 3 |

| 18 | Double diamond structured bicontinuous mesoporous titania templated by a block copolymer for anode material of lithium-ion battery显示文摘Titania has received considerable attention as a promising anode material of Li-ion battery(LIB).Controlling the structure and morphology of titania nanostructures is crucial to govern their performance.Herein,we report a mesoporous titania scaffold with a bicontinuous shifted double diamond(SDD)structure for anode material of LIB.The titania scaffold was synthesized by the cooperative self-assembly of a block copolymer poly(ethylene oxide)-block-polystyrene template and titanium diisopropoxide bis(acetylacetonate)as the inorganic precursor in a mixture solvent of tetrahydrofuran and HCl/water.The structure shows tetragonal symmetry(space group I4_(1)/amd)comprising two sets of diamond networks adjoining each other with the unit cell parameter of a=90 nm and c=127 nm,which affords the porous titania a specific surface area(SSA)of 42 m^(2)·g^(-1)with a mean pore diameter of 38 nm.Serving as an anode material of LIB,the bicontinuous titania scaffold exhibits a high specific capacity of 254 mAh·g^(-1)at the current density of 1 A·g^(-1)and an alluring self-improving feature upon charge/discharge over 1,000 cycles.This study overcomes the difficulty in building up ordered bicontinuous functional materials and demonstrates their potential in energy storage application. | Qingqing Sheng Qian Li Luoxing Xiang Tao Huang Yiyong Mai Lu Han | 2021 | Nano Research2021，14，4： | 2 |
| 19 | Modeling of a space flexible probe–cone docking system based on the Kane method显示文摘Recent developments in micro- and nano-satellites have attracted the interest of the research community worldwide. Many colleges and corporations have launched their satellites in space. Meanwhile, the space flexible probe–cone docking system for micro- and nano-satellites has become an attractive topic. In this paper, a dynamic model of a space flexible probe–cone docking system, in which the flexible beam technology is applied, is built based on the Kane method. The curves of impact force versus time are obtained by the Lagrange model, the Kane model, and the experimental method. The Lagrange model was presented in the reference and verified by both finite element simulation and experiment. The results of the three methods show good agreements on the condition that the beam flexibility and the initial relative velocity change. It is worth mentioning that the introduction of vectorial mechanics and analytical mechanics in the Kane method leads to a large reduction of differential operations and makes the modeling process much easier than that of the Lagrange method. Moreover, the influences of the beam flexibility and the initial relative velocity are discussed. It is concluded that the initial relative velocity of space docking operation should be controlled to a certain value in order to protect the docking system. a 2014 Production and hosting by Elsevier Ltd. on behalf of CSAA & BUAA. | Zhang Xiang Huang Yiyong Chen Xiaoqian Han Wei | 2014 | Chinese Journal of Aeronautics2014，27，2： | 2 |
