| 1 | The Chrysanthemum nankingense Genome Provides Insights into the Evolution and Diversification of Chrysanthemum Flowers and Medicinal Traits显示文摘The Asteraceae (Compositae),a large plant family of approximately 24 000-35 000 species,accounts for^10% of all angiosperm species and contributes a lot to plant diversity.The most representative members of the Asteraceae are the economically important chrysanthemums (Chrysanthemum L.)that diversified through reticulate evolution.Biodiversity is typically created by multiple evolutionary mechanisms such as wholegenome duplication 0NGD)or polyploidization and locally repetitive genome expansion.However,the lack of genomic data from chrysanthemum species has prevented an in-depth analysis of the evolutionary mechanisms involved in their diversification.Here,we used Oxford Nanopore long-read technologyto sequence the diploid Chrysanthemum nankingense genome,which represents one of the progenitor genomes of domesticated chrysanthemums.Our analysis revealed that the evolution of the C.nankingense genome was driven by bursts of repetitive element expansion and WGD events including a recentWGD that distinguishes chrysanthemum from sunflower,which diverged from chrysanthemum approximately 38.8 million years ago.Variations of ornamental and medicinal traits in chrysanthemums are linked to the expansion of candidate gene families by duplication events including paralogous gene duplication.Collectively,our study of the assembled reference genome offers new knowledge and resources to dissect the history and pattern of evolution and diversification of chrysanthemum plants,and also to accelerate their breeding and improvement. | Chi Song Yifei Liu Aiping Song Gangqiang Dong Hongbo Zhao Wei Sun Shyam Ramakrishnan Ying Wang Shuaibin Wang Tingzhao Li Yan Niu Jiafu Jiang Bin Dong Ye Xia Sumei Chen Zhigang Hu Fadi Chen Shilin Chen | 2018 | Molecular Plant2018，11，12： | 24 |
| 2 | Analysis and Numerical Simulation of Rolling Contact between Sphere and Cone显示文摘In non-conforming rolling contact, the contact stress is highly concentrated in the contact area. However, there are some limitations of the special contact model and stress model used for the theoretical study of the phenomenon, and this has prevented in-depth analysis of the associated friction, wear, and failure. This paper is particularly aimed at investigating the area of rolling contact between a sphere and a cone, for which purpose the boundary is determined by the Hertz theory and the geometries of the non-conforming surfaces. The phenomenon of stick-slip contact is observed to occur in the contact area under the condition of no-full-slip(Q < μ·P). Using the two-dimensional rolling contact theory developed by CARTER, the relative positions of the stick and slip regions and the distribution of the tangential force over the contact area are analyzed. Furthermore, each stress component is calculated based on the Mc Ewen theory and the idea of narrow band. The stress equations for the three-dimensional rolling contact between the sphere and the cone are obtained by the principle of superposition, and are used to perform some numerical simulations. The results show that the stress components have a large gradient along the boundary between the stick and slip regions, and that the maximum stress is inversely proportional to the contact coefficient and proportional to the friction coefficient. A new method for investigating the stress during non-classical three-dimensional rolling contact is proposed as a theoretical foundation for the analysis of the associated friction, wear, and failure. | ZHAO Yanling XIA Chengtao WANG Hongbo XUAN Jiaping XIANG Jingzhong LIU Xianli SU Xiangguo | 2015 | Chinese Journal of Mechanical Engineering2015，28，3： | 18 |
| 3 | Natural Variation in CCD4 Promoter Underpins Species-Specific Evolution of Red Coloration in Citrus Peel显示文摘Carotenoids and apocarotenoids act as phytohormones and volatile precursors that influence plant development and confer aesthetic and nutritional value critical to consumer preference.Citrus fruits display considerable natural variation in carotenoid and apocarotenoid pigments.In this study,using an integrated genetic approach we revealed that a 5;c/s-regulatory change at CCD4b encoding CAROTENOID CLEAVAGE DIOXYGENASE 4b is a major genetic determinant of natural variation in C3 0 apocarotenoids responsible for red coloration of citrus peel.Functional analyses demonstrated that in addition the known role in synthesizing 3-citraurin,CCD4b is also responsible for the production of another important C3 0 apocarotenoid pigment,p-citraurinene.Furthermore,analyses of the CCD4b promoter and transcripts from various citrus germplasm accessions established a tight correlation between the presence of a putative 5'c/s-regulatory enhancer within an MITE transposon and the enhanced allelic expression of CCD4b in C3 0 apocarotenoid-rich red-peeled accessions.Phylogenetic analysis provided further evidence that functional diversification of CCD4b and naturally occurring variation of the CCD4b promoter resulted in the stepwise evolution of red peels in mandarins and their hybrids.Taken together,our findings provide new insights into the genetic and evolutionary basis of apocarotenoid diversity in plants,and would facilitate breeding efforts that aim to improve the nutritional and aesthetic value of citrus and perhaps other fruit crops. | Xiongjie Zheng Kaijie Zhu Quan Sun Weiyi Zhang Xia Wang Hongbo Cao Meilian Tan Zongzhou Xie Yunliu Zeng Junli Ye Lijun Chai Qiang Xu Zhiyong Pan Shunyuan Xiao Paul D.Fraser Xiuxin Deng | 2019 | Molecular Plant2019，12，9： | 18 |
| 4 | The Interplay between Artificial Intelligence and Fog Radio Access Networks显示文摘The interplay between artificial intelligence(AI) and fog radio access networks(F-RANs) is investigated in this work from two perspectives: how F-RANs enable hierarchical AI to be deployed in wireless networks and how AI makes F-RANs smarter to better serve mobile devices. Due to the heterogeneity of processing capability, the cloud, fog, and device layers in F-RANs provide hierarchical intelligence via centralized, distributed, and federated learning. In addition, cross-layer learning is also introduced to further reduce the demand for the memory size of the mobile devices. On the other hand, AI provides F-RANs with technologies and methods to deal with massive data and make smarter decisions. Specifically, machine learning tools such as deep neural networks are introduced for data processing, while reinforcement learning(RL) algorithms are adopted for network optimization and decisions. Then, two examples of AI-based applications in F-RANs, i.e., health monitoring and intelligent transportation systems, are presented, followed by a case study of an RL-based caching application in the presence of spatio-temporal unknown content popularity to showcase the potential of applying AI to F-RANs. | Wenchao Xia Xinruo Zhang Gan Zheng Jun Zhang Shi Jin Hongbo Zhu | 2020 | China Communications2020，17，8： | 6 |
| 5 | Core-shell structured MoS_2@S spherical cathode with improved electrochemical performance for lithium-sulfur batteries显示文摘To suppress shuttling effect and improve electrochemical performance of the sulfur cathode for lithiumsulfur batteries, core-shell structured MoS_2 @S spherical cathode has been synthesized through a chemical route using MnC03 as template. The MoS_2 shells consist of MoS_2 nanosheets. For comparison, MoS_2/S cathode has also been synthesized through melting and diffusion of sulfur to commercial MoS_2 powders. The electrochemical performance of the MoS_2@S and MoS_2/S cathodes have been evaluated using cyclic voltammetry, discharge/charge cycling, electrochemical impedance spectroscopy coupled with impedance fitting. The electrochemical performance of the MoS_2@S spherical cathode has been much improved compared with that of MoS_2/S. The capacity of the MoS_2@S spheres can reach 1185.7 mAhg-1 at 0.2 C and 955.1 mAhg^(-1) at 1 C with initial-cycle coulombic efficiency of 90%. The capacity fading of each cycle is 0.1 % during 200 lithiation/delithiation cycles. The MoS_2@S spherical cathode with high cyclic capacity and stability is promising cathode candidate for lithium-sulfur batteries. | Songpu Cheng Xiaohong Xia Hongbo Liu Yuxi Chen | 2018 | Journal of Materials Science & Technology2018，34，10： | 5 |
| 6 | Delay-Based User Association in Heterogeneous Networks with Backhaul显示文摘The Internet of things(IoT) as an important application of future communication networks puts a high premium on delay issues. Thus when Io T applications meet heterogeneous networks(HetNets) where macro cells are overlaid with small cells, some traditional problems need rethinking. In this paper, we investigate the delay-addressed association problem in two-tier Het Nets considering different backhaul technologies. Specifically, millimeter wave and fiber links are used to provide high-capacity backhaul for small cells. We first formulate the user association problem to minimize the total delay which depends on the probability of successful transmission, the number of user terminals(UTs), and the number of base stations(BSs). And then two algorithms for active mode and mixed mode are proposed to minimize the network delay. Simulation results show that algorithms based on mutual selection between UTs and BSs have better performance than those based on distance. And algorithms for mixed modes have less delay than those for active mode when the number of BSs is large enough, compared to the number of UTs. | Wenchao Xia Jun Zhang Shi Jin Hongbo Zhu | 2017 | China Communications2017，14，10： | 4 |

| 9 | Novel Mg-Bi-Mn wrought alloys:The effects of extrusion temperature and Mn addition on their microstructures and mechanical properties显示文摘Designing and developing the Mg alloys with low cost and high performance is of the great significance.Novel Mg-1Bi-xMn(x=0,1and 2 wt.%)extruded alloys,in this work,were fabricated at different extrusion temperatures(220,250 and 300℃).The effects of extrusion temperature and Mn addition on the microstructures and mechanical properties of extruded alloys at room temperature were investigated.The results showed that decreasing the extrusion temperature could refine the average grain size,weaken the basal fiber texture intensity and improve the microstructural homogeneity of extruded alloys.When the Mn element was added to the Mg-1Bi alloy,the average grain size further reduced.Simultaneously,the number fraction of low angle grain boundaries(LAGBs)increased,along with the occurrence of regions without dynamic recrystallization(unDRX).The combined effects of grain refinement and coarse unDRXed structure made the textures of the extruded Mg-1Bi-xMn alloys never obviously change.Besides few large size un-dissolved second phases,fine Mg_(3)Bi_(2) and α-Mn phases were precipitated in the extruded Mg-1Bi-xMn alloys and partial nano-scaleα-Mn particles pined at grain boundaries(GBs)to effectively impede the migration of GBs for grain refinement.Microstructural variations determined the extruded Mg-1Bi-2Mn alloy to exhibit the highest yield strength of~319.2 MPa with the appropriate elongation-to-failure of~13%at the extrusion temperature of 220℃,and they enabled the extruded Mg-1Bi-1Mn alloy to show the highest elongation-to-failure of~26%without the obvious loss of yield strength of~252.1 MPa. | Qinghang Wang Haowei Zhai Lintao Liu Hongbo Xia Bin Jiang Jun Zhao Daolun Chen Fusheng Pan | 2022 | Journal of Magnesium and Alloys2022，10，9： | 2 |
| 10 | A Novel Handoff Algorithm for Hierarchical Cellular Networks显示文摘In this paper, we propose a novel speed and service-sensitive handoff algorithm and analytical model for hierarchical cellular networks.First, we use the Gauss-Markov mobility model to predict the speeds of mobile stations, and divide mobile stations into three classes based on the predicted speeds: fast, medium-speed, and slow.Then, according to the mobility classification,network conditions, and service types, mobile stations will be handoff to the proper target networks prior to the deterioration of the currently operating channel. We further develop an analytical model to evaluate the performance of such a hierarchical system with different speed classes and service types. Simulations and analytical results show that the proposed handoff algorithm can significantly improve the network performance in terms of the handoff failure probability, unnecessary handoff probability, and network throughput, comparing with the traditional algorithms. | Xiaorong Zhu Mengrong Li Wenchao Xia Hongbo Zhu | 2016 | China Communications2016，13，8： | 2 |
| 11 | Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. | Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu | 2023 | Science China(Life Sciences)2023，66，5： | 2 |

| 13 | Linking microbial carbon pump capacity and efficacy to soil organic carbon storage and stability under heavy metal pollution显示文摘Heavy metal pollution can lead to a great loss of soil organic carbon(SOC).However,the microbial mechanisms that link heavy metal pollution to SOC remain poorly understood.Here,we investigated five apple-orchard soils at different distances from a Pb-Zn smelter.After assessing the heavy metal pollution level based on Grade Ⅱ of the national soil environmental quality standard(China),we found SOC stocks and microbial carbon pump(MCP)capacity(i.e.,microbial residue carbon)under medium and heavy pollution levels were significantly lower than those under safe,cordon and light pollution levels.The structural equation model showed causality in the SOC variations linked to pollution level through MCP capacity,which could contribute 77.8% of the variance in SOC storage.This verified MCP capacity can serve as a key parameter for evaluation of SOC storage under heavy metal pollution.Soil MCP efficacy,i.e.,the proportion of microbial residue carbon to SOC,also decreased under medium and heavy pollution.This suggested that,with a heavier pollution level,there was a higher rate of reduction of microbial residue carbon in soil than the rate of reduction of SOC.As MCP efficacy can be a useful assessment of SOC stability,the significantly positive relationship between MCP efficacy and clay content in correlation analysis implied that lower MCP efficacy was correlated with SOC stability under the heavier pollution level.Our study provides valuable insights to identify the mechanisms of microbially mediated C transformation processes that are influenced by heavy metal pollution in agroecosystems. | Xiao Liu Xia Xu Tian Ma Shiwei Zhou Xiaoli Bi Hongbo He Xudong Zhang Weihuan Li | 2023 | Soil Ecology Letters2023，5，2： | 1 |

When fluorescent dyes are doped into the liquid crystal and heavily doped chiral agent system,we demonstrate a wavelength tuning random laser instead of a side-band laser, which is caused by the combined effect of multi-scattering of liquid crystal(LC) and band-gap control. Through rotating the infrared absorbing material on the side of the LC cell, an adjustable range for random lasing of 80 nm by infrared light irradiation was observed. | HONGBO Lu JIAN XING CHENG WEI JIANGYING XIA JUNQING SHA YUNSHENG DING GUOBING ZHANG KANG XIE LONGZHEN QIU ZHIJIA Hu | 2018 | Photonics Research2018，6，5： | 1 |

| 17 | In-situ structural evolution of Bi_(2)O_(3) nanoparticle catalysts for CO_(2) electroreduction显示文摘Under the complex external reaction conditions,uncovering the true structural evolution of the catalyst is of profound significance for the establishment of relevant structure–activity relationships and the rational design of electrocatalysts.Here,the surface reconstruction of the catalyst was characterized by ex-situ methods and in-situ Raman spectroscopy in CO_(2)electroreduction.The final results showed that the Bi_(2)O_(3) nanoparticles were transformed into Bi/Bi_(2)O_(3) two-dimensional thin-layer nanosheets(NSs).It is considered to be the active phase in the electrocatalytic process.The Bi/Bi_(2)O_(3) NSs showed good catalytic performance with a Faraday efficiency(FE)of 94.8%for formate and a current density of 26 mA cm^(−2) at−1.01 V.While the catalyst maintained a 90%FE in a wide potential range(−0.91 V to−1.21 V)and long-term stability(24 h).Theoretical calculations support the theory that the excellent performance originates from the enhanced bonding state of surface Bi-Bi,which stabilized the adsorption of the key intermediate OCHO^(∗) and thus promoted the production of formate. | Hongbo Wang Chongyang Tang Bo Sun Jiangchao Liu Yan Xia Wenqing Li Changzhong Jiang Dong He Xiangheng Xiao | 2022 | International Journal of Extreme Manufacturing2022，4，3： | 1 |

| 19 | Evenness is important in assessing progress towards sustainable development goals显示文摘Sustainable development goals(SDGs)emphasize a holistic achievement instead of cherry-picking a few.However,no assessment has quantitatively considered the evenness among all 17 goals.Here,we propose a systematic method,which first integrates both the evenness and the overall status of all goals,to distinguish the ideal development pathways from the uneven ones and then revisit the development trajectory in China from 2000 to 2015.Our results suggest that,despite the remarkable progress,a bottleneck has occurred in China since 2013 due to the stagnant developments in some SDGs.However,many far-reaching policies in China have been targeting these deficiencies since then,providing a perspective on how a country approaches sustainable development by promoting evenness among all SDGs.Our results also indicate that regions with the slowest progress are the developed provinces,owing to the persistent uneven status of all goals.Our study demonstrates the importance of adopting evenness in assessing and guiding sustainable development. | Yali Liu Jianqing Du Yanfen Wang Xiaoyong Cui Jichang Dong Yanbin Hao Kai Xue Hongbo Duan Anquan Xia Yi Hu Zhi Dong Bingfang Wu Xinquan Zhao Bojie Fu | 2021 | National Science Review2021，8，8： | 1 |
