| 2 | Genetic improvement of heat tolerance in wheat:Recent progress in understanding the underlying molecular mechanisms显示文摘As a cool season crop, wheat(Triticum aestivum L.) has an optimal daytime growing temperature of 15 ℃ during the reproductive stage. With global climate change, heat stress is becoming an increasingly severe constraint on wheat production. In this review, we summarize recent progress in understanding the molecular mechanisms of heat tolerance in wheat. We firstly describe the impact of heat tolerance on morphology and physiology and its potential effect on agronomic traits. We then review recent discoveries in determining the genetic and molecular factors affecting heat tolerance, including the effects of phytohormone signaling and epigenetic regulation. Finally, we discuss integrative strategies to improve heat tolerance by utilization of existing germplasm including modern cultivars, landraces and related species. | Zhongfu Ni Hongjian Li Yue Zhao Huiru Peng Zhaorong Hu Mingming Xin Qixin Sun | 2018 | The Crop Journal2018，6，1： | 4 |

| 4 | Environmental taxation and regional inequality in China显示文摘In order to combat environmental pollution, China enacted the Environmental Protection Tax Law in early 2018. Yet the impacts of the environmental tax on individual regions with different socioeconomic statuses, which are crucial for social justice and public acceptance, remain unclear. Based on a MultiRegional Input-Output(MRIO) table and a nationally regulated tax payment calculation method, this study analyzes the distributional impacts of an environmental tax based upon province’s consumption from both inter-provincial and rural-urban aspects. The national tax revenue based on the current levy mechanism is estimated to be only one seventh of the economic loss from premature mortality caused by ambient particulate matter(PM2.5). The taxation may slightly alleviate urban-rural inequality but may not be helpful with reducing inter-provincial inequality. We further analyze two alternative levy mechanisms. If each province imposes taxes to products it consumes(rather than produces, as in the current mechanism), with the tax rate linearly dependent on its per capita consumption expenditure, this would moderately increase the national tax revenue and significantly reduce inter-provincial inequality.To better compensate for the economic costs of air pollution and reduce regional inequality, it would be beneficial to increase the tax rate nationwide and implement a levy mechanism based on provincially differentiated levels of consumption and economic status. | Jingxu Wang Jintai Lin Kuishuang Feng Peng Liu Mingxi Du Ruijing Ni Lulu Chen Hao Kong Hongjian Weng Mengyao Liu Giovanni Baiocchi Yu Zhao Zhifu Mi Jing Cao Klaus Hubacek | 2019 | Science Bulletin2019，64，22： | 3 |
| 5 | Computation of concentrations of characteristic atoms of alloys in BCC structure显示文摘In this paper,taking Nb-Mo alloy system as an example,the equations of concentration of characteristic atoms of alloys in BCC structure were obtained on the basis of the idea of systematic science of alloys and the number of coordination atoms.The concentrations of characteristic atoms in B2-NbMo type ordered alloys were calculated as functions of ordering degree(s) and composition xMo.When s=smax,the concentrations of characteristic atoms of stoichiometric B2-NbMo intermetallic compound are equal to that of alloys,that is,Nb 8 x0.5 at.,Mo 0 x0.5 at.As ordering degree decreases,characteristic atoms Nb 8A andM o 0A of B2-NbMo type ordered alloy split.And the degree of splitting of characteristic atoms increases with the ordering degree decreasing.Therefore,disordered alloys and various types of ordered alloys can be designed. | PENG HongJian WU Qing LI XiaoBo XIE YouQing | 2011 | Science China(Technological Sciences)2011，54，9： | 3 |
| 6 | Recent advances of composite electrolytes for solid-state Li batteries显示文摘All-solid-state lithium batteries(ASSLBs)are recognized as high energy density batteries system without safety issues within the next generation of batteries.The development of solid electrolytes is the crucial step of ASSLBs.The composite electrolyte has stable physical and electrochemical characteristics,and its comprehensive performance surpasses the individual solid electrolyte,bringing unique vitality to the solid electrolyte.However,their intrinsic weakness limits the development of composite electrolytes.In this review,we provide a comprehensive and in-depth understanding of the challenges and opportunities of composite electrolytes,with special focus on mechanisms of ion transport,nanostructure design towards high ionic conductivity,interfacial issues within electrolytes and electrodes.Furthermore,future development is prospected,which can shed light on researchers in this field and accelerate the industrial production of composite electrolytes. | Laiqiang Xu Jiayang Li Honglei Shuai Zheng Luo Baowei Wang Susu Fang Guoqiang Zou Hongshuai Hou Hongjian Peng Xiaobo Ji | 2022 | Journal of Energy Chemistry2022，31，4： | 2 |
| 7 | Clinical Study on the Effects of Electroacupuncture Combined with Extracorporeal Shock Wave in the Treatment of Periarthritis of Shoulder显示文摘Objective:To investigate the clinical effects of electroacupuncture combined with extracorporeal shock wave in the treatment of periarthritis of shoulder.Methods:136 patients with periarthritis of shoulder admitted to our hospital from September 2018 to September 2019 were randomly divided into two groups by double-blind method.68 patients in the control group were treated with extracorporeal shock wave;68 patients in the observation group were treated with electroacupuncture combined with extracorporeal shock wave.The shoulder joint pain,joint function and activities of daily living were compared between the two groups.Results:The VAS score of shoulder joint pain in the observation group after treatment(1.92±0.24)was lower than that in the control group(3.51±0.32),and the UCLA score of shoulder joint function(31.28±1.96)was higher than that of the control group(27.42±2.36),the differences were statistically significant(P<0.05).After treatment,the active degree of forward flexion and extension of shoulder joint in the observation group was higher than those of the control group,and the activities of daily living was higher than that of the control group,with statistically significant differences(P<0.05)Conclusion:Electroacupuncture combined with extracorporeal shock wave treatment for periarthritis of shoulder has achieved ideal effects,safety and non-invasiveness,and can quickly restore the functions of shoulder joints. | Peng Qi Yu Zhang Shengguang Li Hongjian Yu | 2021 | Journal of Clinical and Nursing Research2021，5，2： | 2 |
| 8 | Cross-Modal Complementary Network with Hierarchical Fusion for Multimodal Sentiment Classification显示文摘Multimodal Sentiment Classification(MSC)uses multimodal data,such as images and texts,to identify the users'sentiment polarities from the information posted by users on the Internet.MSC has attracted considerable attention because of its wide applications in social computing and opinion mining.However,improper correlation strategies can cause erroneous fusion as the texts and the images that are unrelated to each other may integrate.Moreover,simply concatenating them modal by modal,even with true correlation,cannot fully capture the features within and between modals.To solve these problems,this paper proposes a Cross-Modal Complementary Network(CMCN)with hierarchical fusion for MSC.The CMCN is designed as a hierarchical structure with three key modules,namely,the feature extraction module to extract features from texts and images,the feature attention module to learn both text and image attention features generated by an image-text correlation generator,and the cross-modal hierarchical fusion module to fuse features within and between modals.Such a CMCN provides a hierarchical fusion framework that can fully integrate different modal features and helps reduce the risk of integrating unrelated modal features.Extensive experimental results on three public datasets show that the proposed approach significantly outperforms the state-of-the-art methods. | Cheng Peng Chunxia Zhang Xiaojun Xue Jiameng Gao Hongjian Liang Zhengdong Niu | 2022 | Tsinghua Science and Technology2022，27，4： | 2 |

| 12 | Research on atomic states, physical properties and catalytic performance of Ru metal显示文摘Using the one-atom theory (OA) of pure metals, the atomic states of Ru metal with hcp structure, fcc structure, bcc structure and liquid state were determined as fol- lows: [Kr](4dn)3.78(4dc)2.22(5sc)1.77(5sf)0.23,Ψa(fcc-Ru)=[Kr](4dn)3.70(4dc)2.44 (5sc)1.42(5sf)0.44, Ψ a(bcc-Ru)=[Kr](4dn)4.00(4dc)2.22(5sc)1.56(5sf)0.22, Ψ a(L-Ru)=[Kr](4dn)4.00(4dc)2.00(5sc)1.52 (5sf)0.48. The potential curve and physical properties as a function of temperature for hcp-Ru such as lattice constant, cohesive energy, linear thermal expansion coeffi- cient, specific heat and Gibbs energy and so on were calculated quantitatively. The theoretical results are in excellent agreement with experimental value. The rela- tionship between the atomic states and catalytic performance was explained qualitatively and these supplied the designation of Ru metal and relative materials with theoretical instruction and complete data. | PENG HongJian XIE YouQing LIU ShaoQian | 2007 | Science China(Technological Sciences)2007，50，2： | 1 |

| 15 | Research on properties of DO_3- and B2-type ordered alloys and disordered alloys in Nb-Mo alloy system in BCC structure显示文摘Based on the idea of systematic science of alloys, we derived the interaction equations of binary alloys in BCC structure in this paper. According to the basic information of characteristic atoms sequences and characteristic crystals sequences of Nb-Mo alloy system and the concentrations of characteristic atoms of Nb-Mo alloy system, the properties of DO3-Nb3Mo type ordered alloys, B2-NbMo type ordered alloys and DO3-NbMo3 type ordered alloys and disordered alloys were calcu-lated. The results show that the properties of ordered alloys exhibit stronger variations than those of disordered Nb(1-x)Mox alloys when approaching the stoichiometric ratio, whereas the opposite trend occurs when deviating from the stoichiometric ratio. The main reason is that the ordering degree is maximal at the stoichiometric ratio while it decreases linearly when deviating from stoichiometric ratio. On the contrary, the number of bonding electrons among atoms increases with the simultaneous decreasing of the nearly free electrons, which shortens the bond lengths and thus strengthens the crystal bonding. | PENG HongJian ZHOU JiaoLian LI XiaoBo XIE YouQing | 2011 | Science China(Technological Sciences)2011，54，10： | 1 |

| 17 | Low temperature thermodynamic study of the stable and metastable phases of vanadium显示文摘The low temperature thermodynamics of the stable phase of vanadium has been assessed by the polynomial and Debye models from the experimental data available in literature. By means of the con-strained nonlinear least squares curve fitting arithmetic,two sets of parameter values have been de-termined. Expressions of the thermodynamic functions Cp(T) and G(T)-H(298.15 K) at 0―298.15 K are presented. The low temperature thermodynamics of the metastable phase of vanadium can only be extrapolated by the Debye model. The expression of the thermodynamic function Cp(T) at 0―298.15 K is presented. | LI XiaoBo XIE YouQing NIE YaoZhuang PENG HongJian | 2007 | Chinese Science Bulletin2007，52，22： | 1 |
| 18 | Understanding energetic disorder in electron-deficient-core-based non-fullerene solar cells显示文摘Recent advances in material design for organic solar cells(OSCs)are primarily focused on developing near-infrared nonfullerene acceptors,typically A-DA′D-A type acceptors(where A abbreviates an electron-withdrawing moiety and D,an electron-donor moiety),to achieve high external quantum efficiency while maintaining low voltage loss.However,the charge transport is still constrained by unfavorable molecular conformations,resulting in high energetic disorder and limiting the device performance.Here,a facile design strategy is reported by introducing the'wing'(alkyl chains)at the terminal of the DA′D central core of the A-DA′D-A type acceptor to achieve a favorable and ordered molecular orientation and therefore facilitate charge carrier transport.Benefitting from the reduced disorder,the electron mobilities could be significantly enhanced for the'wing'-containing molecules.By carefully changing the length of alkyl chains,the mobility of acceptor has been tuned to match with that of donor,leading to a minimized charge imbalance factor and a high fill factor(FF).We further provide useful design strategies for highly efficient OSCs with high FF. | Jun Yuan Chujun Zhang Honggang Chen Can Zhu Sin Hang Cheung Beibei Qiu Fangfang Cai Qingya Wei Wei Liu Hang Yin Rui Zhang Jidong Zhang Ye Liu Huotian Zhang Weifang Liu Hongjian Peng Junliang Yang Lei Meng Feng Gao Shukong So Yongfang Li Yingping Zou | 2020 | Science China Chemistry2020，63，8： | 1 |
| 19 | The evolving concept of physiological ischemia training vs. ischemia preconditioning显示文摘Ischemic heart diseases are the leading cause of death with increasing numbers of patients worldwide.Despite advances in revascularization techniques,angiogenic therapies remain highly attractive.Physiological ischemia training,which is first proposed in our laboratory,refers to reversible ischemia training of normal skeletal muscles by using a tourniquet or isometric contraction to cause physiologic ischemia for about 4 weeks for the sake of triggering molecular and cellular mechanisms to promote angiogenesis and formation of collateral vessels and protect remote ischemia areas.Physiological ischemia training therapy augments angiogenesis in the ischemic myocardium by inducing differential expression of proteins involved in energy metabolism,cell migration,protein folding,and generation.It upregulates the expressions of vascular endothelial growth factor,and induces angiogenesis,protects the myocardium when infarction occurs by increasing circulating endothelial progenitor cells and enhancing their migration,which is in accordance with physical training in heart disease rehabilitation.These findings may lead to a new approach of therapeutic angiogenesis for patients with ischemic heart diseases.On the basis of the promising results in animal studies,studies were also conducted in patients with coronary artery disease without any adverse effect in vivo,indicating that physiological ischemia training therapy is a safe,effective and non-invasive angiogenic approach for cardiovascular rehabilitation.Preconditioning is considered to be the most protective intervention against myocardial ischemia-reperfusion injury to date.Physiological ischemia training is different from preconditioning.This review summarizes the preclinical and clinical data of physiological ischemia training and its difference from preconditioning. | Jun Ni Hongjian Lu Xiao Lu Minghui Jiang Qingyun Peng Caili Ren Jie Xiang Chengyao Mei Jianan Li | 2015 | The Journal of Biomedical Research2015，29，6： | 1 |
| 20 | Flexible dopamine-sensing fiber based on potentiometric method for long-term detection in vivo显示文摘Achieving real-time,continuous and long-term monitoring of dopamine(DA)in vivo is essential for revealing brain functions and preventing and treating neurogenic diseases.However,it remains challenging to achieve a low limit of detection(LOD)and high neuron-compatibility at the same time for the current microsensors,resulting in the failure of long-term and accurate detection of DA in vivo.A DA-sensing fiber was achieved by the potentiometric method to possess a low LOD of 5 nM,1-3 orders of magnitude lower than amperometry and differential-pulse voltammetry.The sensing fiber showed a wide linear range from 5 to 185 nM that well matched the DA concentration(26-40 nM)in vivo.After implantation,the sensing fiber showed no influence on the firing rates of neurons with the potentiometric test,indicating high neuron-compatibility.It was then integrated with electrophysiology to simultaneously monitor DA variation and electrical signal in the brain,with stable monitoring of DA change in vivo for 8 weeks.The sensing fiber was flexible and stably worked after hundreds of bending,and it showed high sensitivity even after protein adsorption,thus offering a reliable tool for neuroscience. | Liyuan Wang Jiawei Chen Jiajia Wang Hongjian Li Chuanrui Chen Jianyou Feng Yue Guo Hongbo Yu Xuemei Sun Huisheng Peng | 2021 | Science China Chemistry2021，64，10： | 0 |
