| 1 | A Kelch Motif-Containing Serine/Threonine Protein Phosphatase Determines the Large Grain QTL Trait in Rice显示文摘A thorough understanding of the genetic basis of rice grain traits is critical for the improvement of rice (Oryza sativa L.) varieties.In this study,we generated an F 2 population by crossing the large-grain japonica cultivar CW23 with Peiai 64 (PA64),an elite indica small-grain cultivar.Using QTL analysis,17 QTLs for five grain traits were detected on four different chromosomes.Eight of the QTLs were newly-identified in this study.In particular,qGL3-1,a newly-identified grain length QTL with the highest LOD value and largest phenotypic variation,was fine-mapped to the 17 kb region of chromosome 3.A serine/threonine protein phosphatase gene encoding a repeat domain containing two Kelch motifs was identified as the unique candidate gene corresponding to this QTL.A comparison of PA64 and CW23 sequences revealed a single nucleotide substitution (C→A) at position 1092 in exon 10,resulting in replacement of Asp (D) in PA64 with Glu (E) in CW23 for the 364th amino acid.This variation is located at the D position of the conserved sequence motif AVLDT of the Kelch repeat.Genetic analysis of a near-isogenic line (NIL) for qGL3-1 revealed that the allele qGL3-1 from CW23 has an additive or partly dominant effect,and is suitable for use in molecular marker-assisted selection. | Zejun Hu Haohua He Shiyong Zhang Fan Sun Xiaoyun Xin Wenxiang Wang Xi Qian Jingshui Yang Xiaojin Luo | 2012 | Journal of Integrative Plant Biology2012，54，12： | 41 |

| 4 | Effect of China's rapid development on its iconic giant panda显示文摘Anthropogenic factors affect biodiversity and have led to the contraction or extinction of animal populations worldwide.Here,we use historical demographic data,spanning the past 300 years,to show that a rapid distributional contraction of giant pandas took place during the 18th and 19th centuries alongside the increase in human population.Land-use also underwent a significant change across the areas where giant pandas were found because of government agricultural policy and the introduction of new crops.The impact of social development on giant pandas includes habitat loss and fragmentation,and range reductions.Our findings would facilitate the design of effective conservation strategies that seek to conserve and increase current habitats of this iconic species,especially in areas that our analysis has identified as places where pandas have suffered from high human pressure. | ZHU LiFeng HU YiBo ZHANG ZeJun WEI FuWen | 2013 | Chinese Science Bulletin2013，58，17： | 8 |

Polar upper atmospheric observations started at this time. First began at Great Wall Station and then at Zhongshan Station in Antarctica, and later in the Arctic at Yellow River Station, Kjell Henriksen Observatory on Svalbard, and at the China-Iceland Joint Aurora Observatory in Iceland. In this paper, we reviewed the advances in polar upper atmosphere physics(UAP) based on the Chinese national Arctic and Antarctic research over the last five years. These included newly deployed observatories and research instruments in the Arctic and Antarctic; and new research findings, from ground-based observations, about polar ionosphere dynamics, aurora and particle precipitation, polar plasma convection, geomagnetic pulsations and space plasma waves, space weather in the polar regions, simulations of the polar ionosphere-magnetosphere. In conclusion, suggestions were made for future polar upper atmosphere physics research in China. | HE Fang HU Hongqiao YANG Huigen ZHANG Beichen HUANG Dehong LIU Yonghua HU Zejun LIU Jianjun | 2016 | Advances in Polar Science2016，27，4： | 6 |
| 8 | Blind reconnaissance of the pseudo-random sequence in DS/SS signal with negative SNR显示文摘This paper introduces a new theory and algorithm that can be used in blind detection of the carrier wave signal and the pseudo-random sequence of the direct sequence spread spectrum (DS/SS) signal with negative SNR. First, without any a priori knowledge of the DS/SS signal, the carrier wave signal can be detected from DS/SS signal with negative SNR by using stochastic differential equations and energy detection method. Based on this, the pseudo-random sequence can also be blindly detected in DS/SS signal with negative SNR by reducing noise of the nonlinear signal and the algorithm of wavelet multiscale decomposition algorithm. Finally, the computer simulation shows that we can detect the carrier wave signal with SNR=-27 dB and the pseudo-random sequence under error code ratio 10-4 with SNR =-10 dB. | HUANG XianGao HUANG Wei WANG Chao LU ZeJun HU YanHua | 2007 | Science in China(Series F)2007，50，3： | 6 |

| 10 | Extraction of auroral oval boundaries from UVI images: A new FLICM clustering-based method and its evaluation显示文摘Based on the fuzzy local information c-means (FLICM) clustering algorithm, a new method is developed for extracting the equatorward and poleward boundaries of the auroral oval from images acquired by the Ultraviolet Imager (UVI) aboard the POLAR satellite. First, the method iteratively segments the UVI image with the FLICM clustering algorithm, according to an integrity criterion for the segmented auroral oval. Then, possible gaps in the extracted auroral oval are filled, based on prior knowledge of its shape. To evaluate the method objectively, the extracted boundaries are compared with the precipitating electron boundaries determined from DMSP satellite precipitation particle data. The evaluation results demonstrate that the proposed method generates more accurate auroral boundaries than traditional methods. | WANG Qian MENG QingHu HU ZeJun XING ZanYang LIANG JiMin HU HongQiao | 2011 | Advances in Polar Science2011，22，3： | 3 |
| 11 | A new technique for deriving the quiet day curve from imaging riometer data at Zhongshan Station, Antarctic显示文摘A new technique for estimating quiet day curve(QDC)was suggested.To validate the new approach,QDCs were derived from data acquired by the imaging riometer installed at the Chinese Zhongshan Station in Antarctic.The evaluation was performed by comparing the difference between QDC derived by the new technique and those derived by Tanaka’s technique.The results were discussed in terms of the diurnal variation and discrepancy.Also,cosmic noise absorption(CNA)images were built using both techniques in order to evaluate the implications of the changes when obtaining them using different methods of the QDC determination.The influence of the multiplicative factor value on the QDC determination in Tanaka’s technique was evaluated. | HE Fang HU HongQiao HU ZeJun LIU RuiYuan | 2014 | Science China(Technological Sciences)2014，57，10： | 2 |
| 12 | Chinese Antarctic Magnetometer Chain at the Cusp Latitude显示文摘A Chinese Antarctic Magnetometer(CAM) chain from Zhongshan Station(ZHS) to Dome-A(DMA) has been established since February 2009.A regular magnetometer is operated at ZHS,and four low power magnetometers are operated along the interior route from ZHS to DMA in the cusp latitude,extending over a distance of 1260 km.These stations fill an important void in the Antarctic magnetometer network.Furthermore,the CAM chain is magnetically conjugated with the Arctic region reaching from the Svalbard archipelago to Daneborg,on the east coast of Greenland.Conjugate measurements using the Arctic and Antarctic magnetometers provide excellent opportunities to investigate phenomena related to the coupling of the solar wind to the magnetosphere and ionosphere,such as magnetic impulse events,flux transfer events,traveling convection vortices and ultra-low frequency waves. | LIU Yonghua HU Hongqiao YANG Huigen ZHANG Beichen SUN Bo WEI Fuhai LIU Yang LIU Jianjun WANG Rui CHEN Zhuotian HU Zejun HAN Desheng SHI Guitao HU Zhengyi WANG Tao AN Chunlei Mike Rose | 2016 | Advances in Polar Science2016，27，2： | 2 |
| 13 | Scattered seeding of CAR T cells in solid tumors augments anticancer efficacy显示文摘Chimeric antigen receptor T cell(CAR T) therapy was a milestone in the treatment of relapsed and refractory B cell malignancies. However, beneficial effects of CAR T cells have not been obtained in solid tumors yet. Herein, we implement a porous microneedle patch that accommodates CAR T cells and allows in situ penetration-mediated seeding of CAR T cells when implanted in the tumor bed or in the post-surgical resection cavity. CAR T cells loaded in the pores of the microneedle tips were readily escorted to the tumor in an evenly scattered manner without losing their activity. Such microneedle-mediated local delivery enhanced infiltration and immunostimulation of CAR T cells as compared to direct intratumoral injection. This tailorable patch offers a transformative platform for scattered seeding of living cells for treating a variety of tumors. | Hongjun Li Zejun Wang Edikan A.Ogunnaike Qing Wu Guojun Chen Quanyin Hu Tianyuan Ci Zhaowei Chen Jinqiang Wang Di Wen Hongwei Du Jie Jiang Jie Sun Xingcai Zhang Gianpietro Dotti Zhen Gu | 2022 | National Science Review2022，9，3： | 2 |
| 14 | Simultaneous optical and radar observations of poleward moving auroral forms under different IMF conditions显示文摘Using high temporal resolution optical data obtained from three-wavelength all-sky imagers at Chinese Yellow River Station in the Arctic, together with the EISCAT Svalbard radar (ESR) and SuperDARN radars, we investigated the dayside poleward moving auroral forms (PMAFs) and the associated plasma features in the polar ionosphere under different interplanetary magnetic field (IMF) conditions, between 0900 and 1010 UT on 22 December 2003. Simultaneous optical and ESR observations revealed that all PMAFs were clearly associated with pulsed particle precipitations. During northward IMF, particles can precipitate into lower altitudes and reach the ionospheric E-region, and there is a reverse convection cell associated with these PMAFs. This cell is one of the typical signatures of the dayside high-latitude (lobe) reconnection in the polar ionosphere. These results indicate that the PMAFs were associated with the high-latitude reconnection. During southward IMF, the PMAFs show larger latitudinal motion, indicating a longer mean lifetime, and the associated ionospheric features indicate that the PMAFs were generated by the dayside low-latitude reconnection. | XING Zanyang YANG Huigen HAN Desheng WU Zhensen LIU Junming HU Zejun ZHANG Qinghe LIU Yonghua ZHANG Beichen HU Hongqiao | 2012 | Advances in Polar Science2012，23，4： | 2 |
| 15 | Dayside poleward moving auroral forms and ionospheric convection under stable interplanetary magnetic field (IMF) conditions显示文摘Using high temporal resolution optical data obtained from three-wavelength all-sky imagers over six winters continuously at Yellow River Station (78.92°N,11.93°E) in Arctic,we statistically investigated the dependence of location of poleward moving auroral forms (PMAFs) on the interplanetary magnetic field (IMF) B z and B y components as a function of MLT and MLAT under stable IMF conditions.It is found that more PMAFs occurred in lower latitude for Bz<0 and there was less evident IMF B y-related prenoon-postnoon asymmetry for Bz<0 than for Bz>0.We found that the PMAFs were distributed over a wide range of MLT when Bz<0,which indicates that the reconnection X-line might spread like an 'S' shape.However,during northward IMF,PMAFs were observed predominantly prenoon for IMF By>0 and postnoon for IMF By<0 associating with the effect of the high-latitude reconnection,which is largely consistent with the theoretical model of the convection flow. | XING ZanYang YANG HuiGen HAN DeSheng WU ZhenSen LIU JunMing HU ZeJun ZHANG QingHe HU HongQiao LIU YongHua | 2013 | Science China(Technological Sciences)2013，56，4： | 2 |
| 16 | An improved YOLOv3-tiny algorithm for vehicle detection in natural scenes显示文摘YOLO(You Only Look Once),as a target detection algorithm with good speed and precision,is widely used in the industry.In the process of driving,the vehicle image captured by the driving camera is detected and it extracts the license plate and the front part of the vehicle.Compared with the network structure of YOLOv3-tiny algorithm,the acquisition method of anchor box is improved by combining the Birch algorithm.In order to improve the real-time performance,the original two-scale detection is added to the multi-scale prediction of three-scale detection to ensure its accuracy.Finally,the experimental results show that the improved YOLOv3-tiny network structure proposed in this study can improve the performance of mean-average-precision,intersection over union and speed by 5.99%,17.52%and 48.4%,respectively,and the algorithm has certain robustness. | Bingqiang Huang Haiping Lin Zejun Hu Xinjian Xiang Jiana Yao | 2021 | IET Cyber-Systems and Robotics2021，3，3： | 2 |

| 18 | Auroral event detection using spatiotemporal statistics of local motion vectors显示文摘The analysis and exploration of auroral dynamics are very significant for studying auroral mechanisms.This paper proposes a method based on auroral dynamic processes for detecting auroral events automatically.We first obtained the motion fields using the multiscale fluid flow estimator.Then,the auroral video frame sequence was represented by the spatiotemporal statistics of local motion vectors.Finally,automatic auroral event detection was achieved.The experimental results show that our methods could detect the required auroral events effectively and accurately,and that the detections were independent on any specific auroral event.The proposed method makes it feasible to statistically analyze a large number of continuous observations based on the auroral dynamic process. | WANG Qian LIANG Jimin HU Zejun | 2013 | Advances in Polar Science2013，24，3： | 1 |
| 19 | Auxin signaling module OsSK41-OsIAA10-OsARF regulates grain yield traits in rice显示文摘Auxin is an important phytohormone in plants, and auxin signaling pathways in rice play key roles in regulating its growth, development, and productivity. To investigate how rice grain yield traits are regulated by auxin signaling pathways and to facilitate their application in rice improvement, we validated the functional relationships among regulatory genes such as OsIAA10, OsSK41, and OsARF21 that are involved in one of the auxin(OsIAA10) signaling pathways. We assessed the phenotypic effects of these genes on several grain yield traits across two environments using knockout and/or overexpression transgenic lines.Based on the results, we constructed a model that showed how grain yield traits were regulated by OsIAA10 and OsTIR1, OsAFB2, and OsSK41 and OsmiR393 in the OsSK41-OsIAA10-OsARF module and by OsARF21 in the transcriptional regulation of downstream auxin response genes in the OsSK41-OsIAA10-OsARF module. The population genomic analyses revealed rich genetic diversity and the presence of major functional alleles at most of these loci in rice populations. The strong differentiation of many major alleles between Xian/indica and Geng/japonica subspecies and/or among modern varieties and landraces suggested that they contributed to improved productivity during evolution and breeding. We identified several important aspects associated with the genetic and molecular bases of rice grain and yield traits that were regulated by auxin signaling pathways.We also suggested rice auxin response factor(OsARF) activators as candidate target genes for improving specific target traits by overexpression and/or editing subspecies-specific alleles and by searching and pyramiding the ‘best' gene allelic combinations at multiple regulatory genes in auxin signaling pathways in rice breeding programs. | Fuying Ma Fan Zhang Yu Zhu Dengyong Lan Peiwen Yan Ying Wang Zejun Hu Xinwei Zhang Jian Hu Fuan Niu Mingyu Liu Shicong He Jinhao Cui Xinyu Yuan Ying Yan Shujun Wu Liming Cao Hongwu Bian Jinshui Yang Zhikang Li Xiaojin Luo | 2023 | Journal of Integrative Plant Biology2023，65，7： | 1 |
