| 1 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021，64，1： | 122 |
| 2 | The role of magmatism in the thinning and breakup of the South China Sea continental margin显示文摘INTRODUCTION Magmatism plays a key role in the process of continental margin breakup and ocean formation.Even in the extremely magma-poor Iberia and Newfoundland margin,studies of field outcrops have shown that syn-rift magmatism had participated in rifting from a very early stage and contributed directly to the rifting process.The final transition from exhumed continental mantle to the ocean formation is also triggered by the accumulation and eruption of magma[1]. | Zhen Sun Jian Lin Ning Qiu Zhimin Jian PinXian Wang Xiong Pang Jinyun Zheng Benduo Zhu | 2019 | National Science Review2019，6，5： | 34 |
| 3 | Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation. | Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu | 2019 | Cancer Biology & Medicine2019，16，1： | 14 |
| 4 | Quaternary biogenic opal records in the South China Sea: Linkages to East Asian monsoon, global ice volume and orbital forcing显示文摘Particulate fluxes investigated in the central South China Sea (SCS) during 1993―1996 indicate that opal flux can be used to show primary productivity change, which provides a foundation for tracing the evolutionary relationship between the surface productivity and East Asian monsoon in the SCS during the late Quaternary glacial and interglacial periods. Based on the studies of opal % and their mass accumulation rates (MAR) at the six sites recovered from the SCS during the “Resolution” ODP Leg 184 and “Sonne” 95 cruise of the Sino-Germany cooperation, opal % and their MARs increased evidently in the northern sites since 470―900 ka, and they enhanced and reduced, respectively, during the glacial and interglacial periods. Whereas they increased obviously in the southern sites since 420―450 ka, and they augmented and declined, respectively, during the interglacial and glacial periods. The vari- ability in opal % and their MARs in the late Quaternary glacial cyclicity indicate the “seesaw” pattern of surface productivity in the SCS. The winter monsoon intensified during the glacial periods, surface productivity increased and decreased, respectively, in the northern and southern SCS. The summer monsoon strengthened during the interglacial periods, surface productivity increased and decreased, respectively, in the southern and northern SCS. The cross spectral analyses between the opal % in the northern and southern SCS during the Quaternary and global ice volume (δ 18O) and orbital forcing (ETP) indicate that the East Asian winter and summer monsoons could be ascribed to the different drive mechanisms. On the orbital time scale, the global ice volume change could be a dominant factor for the winter monsoon intension and temporal variations. As compared with the winter monsoon, the correlative summer solar radiation with the obliquity and precession in the Northern Hemisphere could be a mostly controlling factor for the summer monsoon intension and temporal variations. | WANG RuJian JIAN ZhiMin XIAO WenShen TIAN Jun LI JianRu CHEN RongHua ZHENG YuLong CHEN JianFang | 2007 | Science China Earth Sciences2007，50，5： | 9 |
| 5 | Effect of circumferential strain rate on dynamic recrystallization and texture of Mg-13Gd-4Y-2Zn-0.5Zr alloy during rotary backward extrusion显示文摘Gleeble-3500 thermal simulator was applied to realize the rotary backward extrusion forming of Mg-13Gd-4Y-2Zn-0.5Zr(wt%)alloy at different circumferential strain rate from 0.009 s^(-1)to 0.027 s^(-1)at 400℃and the dynamic recrystallization mechanism and texture evolution were studied.The results show that the grain size of the alloy was obviously refined after rotary backward extrusion.As the circumferenlial strain rate increased,the dynamic recrystallization fraction gradually increased causing the grain size decreased and the distribution of microstructure became more uniform.At the same time,the texture of{0001},{10-10},{11-20}was weakened and the grain orientation distribution became more random.With the increase of circumferential strain rate,the discontinuous dynamic recrystallization mechanism became dominant,which promoted the weakening of texture and grain refinement of the alloy. | Yingze Meng Jianmin Yu Guanshi Zhang Yaojin Wu Zhimin Zhang Zheng Shi | 2020 | Journal of Magnesium and Alloys2020，8，4： | 7 |
| 6 | The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability. | Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding | 2022 | Molecular Plant2022，15，5： | 6 |
| 7 | Regulation of tumor cell migration by protein tyrosine phosphatase (PTP)-proline-, glutamate-, serine-,and threonine-rich sequence(PEST)显示文摘Protein tyrosine phosphatase (PTP)-proline-,glutamate-,serine-,and threonine-rich sequence (PEST) is ubiquitously expressed and is a critical regulator of cell adhesion and migration.PTP-PEST activity can be regulated transcriptionally via gene deletion or mutation in several types of human cancers or via post-translational modifications,including phosphorylation,oxidation,and caspase-dependent cleavage.PTP-PEST interacts with and dephosphorylates cytoskeletal and focal adhesion-associated proteins.Dephos-phorylation of PTP-PEST substrates regulates their enzymatic activities and/or their interaction with other proteins and plays an essential role in the tumor cell migration process. | Yanhua Zheng Zhimin Lu | 2013 | Chinese Journal of Cancer2013，32，2： | 4 |
| 8 | Identifi cation and characterization of the bZIP transcription factor family in yellowhorn显示文摘The basic leucine zipper(bZIP)transcription factor family is one of the largest and most diverse families in plants,regulating plant growth and development and playing an essential role in response to abiotic and biotic stresses.However,little is known about the biological functions of bZIP proteins in yellowhorn(Xanthoceras sorbifolium).Recently,64 XsbZIP genes were identifi ed in the yellowhorn genome and found to be disproportionately distributed in linkage groups.The XsbZIP proteins clustered into 11 groups based on their phylogenetic relationships with AtbZIP,ZmbZIP and GmbZIP proteins.Five intron patterns in the basic and hinge regions and additional conserved motifs were defi ned,both supporting the group classifi cation and possibly contributing to their functional diversity.Compared to tandem duplication,the segment duplication greatly contributed to the expansion of yellowhorn bZIP genes.In addition,most XsbZIP genes harbor several stress responsive cis-elements in their promoter regions.Moreover,the RNA-seq and qRT-PCR data indicated XsbZIP genes were extensively involved in response to various stresses,including salt(NaCl),cold and abscisic acid,with possibly diff erent molecular mechanisms.These results provide a new understanding of the biological functions of bZIP transcription factors in yellowhorn. | Qiaoying Chang Xin Lu Zhi Liu Zhimin Zheng Song Yu | 2021 | Journal of Forestry Research2021，32，1： | 4 |
| 9 | Molecular mechanisms of growth depression in broiler chickens(Gallus Gallus domesticus)mediated by immune stress:a hepatic proteome study显示文摘Background:Immunological stress decreases feed intake,suppresses growth and induces economic losses.However,the underlying molecular mechanism remains unclear.Label-free liquid chromatography and mass spectrometry(LC-MS)proteomics techniques were employed to investigate effects of immune stress on the hepatic proteome changes of Arbor Acres broilers(Gallus Gallus domesticus)challenged with Escherichia coli lipopolysaccharide(LPS).Results:Proteomic analysis indicated that 111 proteins were differentially expressed in the liver of broiler chickens from the immune stress group.Of these,28 proteins were down-regulated,and 83 proteins were up-regulated in the immune stress group.Enrichment analysis showed that immune stress upregulated the expression of hepatic proteins involved in defense function,amino acid catabolism,ion transport,wound healing,and hormone secretion.Furthermore,immune stress increased valine,leucine and isoleucine degradation pathways.Conclusion:The data suggests that growth depression of broiler chickens induced by immune stress is triggered by hepatic proteome alterations,and provides a new insight into the mechanism by which immune challenge impairs poultry production. | Aijuan Zheng Anrong Zhang Zhimin Chen Shoaib Ahmed Pirzado Wenhuan Chang Huiyi Cai Wayne L.Bryden Guohua Liu | 2021 | Journal of Animal Science and Biotechnology2021，12，4： | 4 |
| 10 | Dramatic transition between electric and magnetic rotations in ^(106)Ag显示文摘The lifetimes for the states of magnetic dipole band in106Ag have been measured using the Doppler-shift attenuation method via the reaction of100Mo(11B,5n)106Ag at a beam energy of 60 MeV.The reduced transition strengths of the magnetic dipole band,the B(M1)/B(E2)ratios together with the signature of the level energy as a function of angular momentum for the positive parity states of106Ag show that a drastic change of excitation mode,that is,from electric rotation to magnetic rotation,occurs within one unit of spin at around Iπ=12+.Theoretical calculations based on the triaxial projected shell model consistently reproduce the experimental data and provide an explanation on the nature of observed phenomena such that the dynamical drift of the rotational axis suddenly from the principal axis to the tilted one,along the positive parity bands of106Ag. | ZHENG Yun ZHU LiHua CHEN YongShou WU XiaoGuang HE ChuangYe HAO Xin LIU Ying WANG ZhiMin LI XueQin LI GuangSheng GAO ZaoChun SUN HuiBin | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，9： | 4 |
| 11 | Construction of multi-factor identification model for real-time monitoring and early warning of mine water inrush显示文摘As a new technical means that can detect abnormal signs of water inrush in advance and give an early warning,the automatic monitoring and early warning of water inrush in mines has been widely valued in recent years.Due to the many factors affecting water inrush and the complicated water inrush mechanism,many factors close to water inrush may have precursory abnormal changes.At present,the existing monitoring and early warning system mainly uses a few monitoring indicators such as groundwater level,water influx,and temperature,and performs water inrush early warning through the abnormal change of a single factor.However,there are relatively few multi-factor comprehensive early warning identification models.Based on the analysis of the abnormal changes of precursor factors in multiple water inrush cases,11 measurable and effective indicators including groundwater flow field,hydrochemical field and temperature field are proposed.Finally,taking Hengyuan coal mine as an example,6 indicators with long-term monitoring data sequences were selected to establish a single-index hierarchical early-warning recognition model,a multi-factor linear recognition model,and a comprehensive intelligent early-warning recognition model.The results show that the correct rate of early warning can reach 95.2%. | Xin Wang Zhimin Xu Yajun Sun Jieming Zheng Chenghang Zhang Zhongwen Duan | 2021 | International Journal of Mining Science and Technology2021，31，5： | 3 |
| 12 | Motif-mediated Au25(SPh)5(PPh3)ioX2 nanorods with conjugated electron delocalization显示文摘We developed a general and effective strategy to afford rod-like [Au25(SPh)5(PPh3)10X2]X2 (X = Cl/Br) nanoclusters, capped by conjugated delocalized pπ electron mediated ligands. The detailed atomic structure of these materials was resolved by synchrotron radiation X-ray diffraction (SRXRD) combined with electrospray ionization mass spectrometry (ESI-MS) and UV–vis analyses. The Au17(SR)3(PPh3)6X2minimum asymmetric unit, with exposed Au atoms at the center, can serve as an important model to understand the transformation of homogold nanoclusters into alloy nanoclusters. The conjugated delocalized pπ electrons of the thiolate ligands can effectively tune the electronic properties of the Au25 kernel, as qualitatively evidenced by the energy gaps measured by UV–vis experiments and density functional theory (DFT) calculations. The delocalized electrons distinctly flow to the orbitals of the Au25 kernel via the S atoms of the aromatic thiolates. The ESI-MS analysis indicates that Au3 clusters are formed during the etching reactions, which provide an opportunity to gain insight into the intriguing conversion pathway of the Aun(PPh3)mXy precursor to the final Au25 nanorods. Finally, the thiophenol-protected Au25 nanorods, immobilized on activated carbon, show good catalytic activity in the aerobic oxidation of glucose to gluconic acid (74% glucose conversion and 100% selectivity for gluconic acid), much higher than that of the aliphatic Au25 analogue. The Au25(SPh)5(PPh3)10X2 catalyst yields a turnover frequency (TOF) of 13.5 s^–1, higher than that of commercial catalysts such as Pd/activated carbon (AC) and Pd-Bi/AC. The insight obtained from this study will support the development and design of efficient nanogold catalysts for special oxidation reactions. | Kai Zheng Jiangwei Zhang Dan Zhao Yong Yang Zhimin Li Gao Li | 2019 | Nano Research2019，12，3： | 3 |
| 13 | Identification of yellowhorn(Xanthoceras sorbifolium)WRKY transcription factor family and analysis of abiotic stress response model显示文摘WRKY transcription factors are widely distributed in higher plants and play important roles in many biological processes,including stress resistance.The recently published genome sequence of yellowhorn,an oil tree with robust resistance to cold,drought,heat,salt and alkali,provides an excellent opportunity to identify and characterize the entire yellowhorn WRKY protein family and a basis for the study of abiotic stress resistance of WRKY gene family in forest species.In the present comprehensive analysis of WRKY transcription factors in yellowhorn,65 WRKY genes were identified and defined based on their location on the chromosome.According to their structure and phylogenetic relationships,XsWRKY genes clustered into WRKY groupsⅠ-Ⅲ.Segmental duplication events played a significant role in the expansion of WRKY gene family.Furthermore,transcriptomic data and real-time quantitative PCR analysis showed that expression of XsWRKY genes responding to salt and drought stresses and a hormone treatment.We also determined structures of the encoded proteins,c is-elements of the promoter region,and expression patterns.These results provide a foundation for the study of the biological function of WRKY transcription factors in yellowhorn. | Zhi Liu Saiyinduleng Qiaoying Chang Chuwen Cheng Zhimin Zheng Song Yu | 2021 | Journal of Forestry Research2021，32，3： | 3 |

| 15 | pH-sensitive and biodegradable charge-transfer nanocomplex for second near-infrared photoacoustic tumor imaging显示文摘The emerging technique of photoacoustic imaging,especially in the near infra-red(NIR)window,permits high resolution,deep-penetration,clinically reliable sensing.However,few contrast agents are available that can specifically respond to intricate biological environments,and which are biodegradable and biocompatible.Herein,we in troduce a new class of pH-sensitive orga nic photoacoustic con trast age nt that operates in the second NIR window(NIR-II,960-1,700 nm),which is derived from the self-assembled charge-transfer nanocomplex(CTN)by 3,3',5,5'-tetramethylbenzidine(TMB)and its dication structure(TMB++).The unique NIR-ll-responsive CTN can specifically respond to pH change in the physiological range and allows noninvasive and sensitive visualization of the tumor acidic microenvironment(e.g.at pH5)in mice with higher signal-to-noise ratio.The CTN is biodegradable under physiological conditions(e.g.pH 7.4),which alleviates the biosafety concern of nan oparticle accumulati on in vivo.These results clearly show the pote ntial of the TMB/TMB++-based CTN as a promisi ng pH-activated and biodegradable molecular probe for specific tumor photoacoustic imaging in the NIR-II region. | Zhimin Wang Paul Kumar Upputuri Xu Zhen Ruochong Zhang Yuyan Jiang Xiangzhao Ai Zhijun Zhang Ming Hu Zhenyu Meng Yunpeng Lu Yuanjing Zheng Kanyi Pu Manojit Pramanik Bengang Xing | 2019 | Nano Research2019，12，1： | 3 |
| 16 | Reconstruction of the starting time series of rainy season in Yunnan and the evolvement of summer monsoon during 1711-1982显示文摘According to the textual research into the historical documents dominated by ar- chives yearly, as well as the verification with several other kinds of data, the later or earlier starting time of the rainy seasons in Yunnan during 1711–1982 has been reconstructed. The analysis indicates that there are obvious fluctuations in the starting date of the rainy seasons in Yunnan in a year or years, and long fluctuation on the decadal scale. The rainy season comes earlier in the early 18th century, later in the 19th century and earlier again in the 20th century. This reflects to a certain degree the gradual change of the summer monsoon in Yunnan. There exists an obvious quasi-3 years cycle, which is related to El-Nino’s quasi-3 years cycle, and a 11.3-year cycle which is notably related to the 11-year cycle of the solar activity of starting date of the rainy seasons in Yunnan. Meanwhile, the dissertation finds that the El-Nino is very important to the starting date of the rainy seasons in Yunnan. The starting date of the rainy seasons in Yunnan often comes later or normally in the year of El-Nino. However, there is an obvious imperfect period in such influence, which in turn may mean that there is a certain fluctuation in the effect of ENSO on Asian summer monsoon. | YANG Yuda MAN Zhimin ZHENG Jingyun | 2007 | Journal of Geographical Sciences2007，17，2： | 2 |
| 17 | Microstructure evolution,texture and mechanical properties of a Mg-Gd-Y-Zn-Zr alloy fabricated by cyclic expansion extrusion with an asymmetrical extrusion cavity:The influence of passes and processing route显示文摘In the present work,two processing routes(A and B)with 3 CEE-AEC passes are performed on Mg-13 Gd-4 Y-2 Zn-0.4 Zr alloys,and the resultant microstructure evolution,texture analysis and mechanical properties are investigated systematically.The core difference between the two processing routes is the orientation between the expansion and extrusion steps,i.e.,they are parallel to each other for on route A and perpendicular to each other for route B.The results show that a remarkable grain refinement is achieved via both processing routes due to dynamic recrystallization(DRX).Fine equiaxed grains are observed in the samples processed with route B with a final size of 3.6±0.4μm compared to the grain size of 4.5±0.5μm with route A.With an increasing number of CEE-AEC passes,the overall texture intensity decreases,and the basal texture gradually changes to the mixed texture components.The shear deformation introduced by the asymmetrical extrusion cavity promotes a broad angular distribution of the basal planes on routes A and B,leading to an obvious increase in the Schmid factor for the activation of the basal a slip system.The tensile test at ambient temperature reveals that the comprehensive mechanical properties are improved,and the conventional mechanical anisotropy of as-received alloys is alleviated by successive CEE-AEC processing,which is mainly derived from the competitive balance relation between the grain refinement and texture modification. | Zhaoming Yan Xubin Li Jie Zheng Zhimin Zhang Qiang Wang Kaihua Xu Hongzhi Fan Guanshi Zhang Jiaxuan Zhu Yong Xue | 2021 | Journal of Magnesium and Alloys2021，9，3： | 2 |
| 18 | A gene that underwent adaptive evolution, LAC2 (LACCASE), in Populus euphratica improves drought tolerance by improving water transport capacity显示文摘Drought severely limits plant development and growth;accordingly,plants have evolved strategies to prevent water loss and adapt to water deficit conditions.However,experimental cases that corroborate these evolutionary processes are limited.The LACCASEs(LACs)family is involved in various plant development and growth processes.Here,we performed an evolutionary analysis of LACs from Populus euphratica and characterized the functions of LACs in Arabidopsis and poplar.The results showed that in PeuLACs,multiple gene duplications led to apparent functional redundancy as the result of various selective pressures.Among them,PeuLAC2 underwent strong positive selection.Heterologous expression analyses showed that the overexpression of PeuLAC2 alters the xylem structure of plants,including thickening the secondary cell wall(SCW)and increasing the fiber cell length and stem tensile strength.Altogether,these changes improve the water transport capacity of plants.The analysis of the physiological experimental results showed that PeuLAC2-OE lines exhibited a stronger antioxidant response and greater drought tolerance than WT.Three genes screened by transcriptome analysis,NAC025,BG1,and UGT,that are associated with SCW synthesis and drought stress were all upregulated in the PeuLAC2-OE lines,implying that the overexpression of PeuLAC2 thickened the SCW,improved the water transport capacity of the plant,and further enhanced its drought tolerance.Our study highlights that genes that have undergone adaptive evolution may participate in the development of adaptive traits in P.euphratica and that PeuLAC2 could be a candidate gene for molecular genetic breeding in trees. | Zhimin Niu Guiting Li Hongyin Hu Jiaojiao Lv Qiwei Zheng Jianquan Liu Dongshi Wan | 2021 | Horticulture Research2021，8，1： | 2 |
| 19 | Anomaly detection in smart grid based on encoder-decoder framework with recurrent neural network显示文摘Anomaly detection in smart grid is critical to enhance the reliability of power systems.Excessive manpower has to be involved in analyzing the measurement data collected from intelligent motoring devices while performance of anomaly detection is still not satisfactory.This is mainly because the inherent spatio-temporality and multi-dimensionality of the measurement data cannot be easily captured.In this paper,we propose an anomaly detection model based on encoder-decoder framework with recurrent neural network(RNN).In the model,an input time series is reconstructed and an anomaly can be detected by an unexpected high reconstruction error.Both Manhattan distance and the edit distance are used to evaluate the difference between an input time series and its reconstructed one.Finally,we validate the proposed model by using power demand data from University of California,Riverside(UCR) time series classification archive and IEEE 39 bus system simulation data.Results from the analysis demonstrate that the proposed encoder-decoder framework is able to successfully capture anomalies with a precision higher than 95%. | Zheng Fengming Li Shufang Guo Zhimin Wu Bo Tian Shiming Pan Mingming | 2017 | The Journal of China Universities of Posts and Telecommunications2017，24，6： | 2 |
