| 1 | FUSAR-Ship:building a high-resolution SAR-AIS matchup dataset of Gaofen-3 for ship detection and recognition显示文摘Gaofen-3 (GF-3) is China's first civil C-band fully polarimetric spaceborne synthetic aperture radar (SAR) primarily missioned for ocean remote sensing and marine monitoring. This paper proposes an automatic sea segmentation, ship detection, and SAR-AIS matchup procedure and an extensible marine target taxonomy of 15 primary ship categories, 98 sub-categories, and many non-ship targets. The FUSAR-Ship high-resolution GF-3 SAR dataset is constructed by running the procedure on a total of 126 GF-3 scenes covering a large variety of sea, land, coast, river and island scenarios. It includes more than 5000 ship chips with AIS messages as well as samples of strong scatterer, bridge, coastal land, islands, sea and land clutter. FUSAR-Ship is intended as an open benchmark dataset for ship and marine target detection and recognition. A preliminary 8-type ship classification experiment based on convolutional neural networks demonstrated that an average of 79% test accuracy can be achieved. | Xiyue HOU Wei AO Qian SONG Jian LAI Haipeng WANG Feng XU | 2020 | Science China(Information Sciences)2020，63，4： | 19 |

| 3 | Phylogenetic Relationships of the Genus Paramesotriton(Caudata: Salamandridae) with the Description of a New Species from Qixiling Nature Reserve, Jiangxi, Southeastern China and a Key to the species显示文摘The matrilineal genealogy of the genus Paramesotriton is hypothesized based on DNA sequences from mitochondrial NADH subunit two(ND2) and its flanking tRNAs(tRNATrp and a partial tRNAAla). The genealogy identifies a highly divergent, unnamed lineage from Qixiling Nature Reserve, Jiangxi, China and places it as the sister taxon of P. chinensis. The newly discovered population differs from other congeners by several features of external morphology including having large clusters of dark brown conical warts on the dorsum of the head, lateral surface of the body and dorsolateral ridges. Its intermittent dorsal vertebral ridge is the same color as other parts of the dorsum and tail narrows gradually from the base to the tip. Further, the new population differs from all congeners by an uncorrected P-distance of more than 9.38% in ND2. Consequently, we describe the new species of Asian warty newt(Salamandridae) as Paramesotriton qixilingensis sp. nov. | Zhiyong YUAN Haipeng ZHAO Ke JIANG Mian HOU Lizhong HE Robert W.MURPHY Jing CHE | 2014 | Asian Herpetological Research2014，5，2： | 7 |
| 4 | Mathematical analysis and its experimental comparisons for the accumulative roll bonding(ARB)process with different superimposed layers显示文摘Based on the traditional two-layer accumulative roll bonding(TARB),the geometrical variations and mathematical relationship during the four-layer accumulative roll bonding(FARB)were derived and summarized.Furthermore,the multi-layer accumulative roll bonding(MARB)technology was proposed and the geometrical variations and mathematical relationship of MARB were simultaneously derived and summarized.Experimentally,Mg-14Li-3Al-2Gd(LAGd1432)sheets were fabricated by TARB and FARB,respectively.Compared with the TARB,the FARB has a higher accumulative efficiency in terms of accumulative layers,total number of interfaces,interface spacing,total deformation and equivalent strain.Therefore,the FARB-processed sheets in lower cycles have the similar microstructure and mechanical properties of the TARB-processed sheets in higher cycles.In addition,FARB process can further break through the deformation limit of TARB process in a single cycle through adopting two-step rolling in one cycle with 50%deformation in one pass and 75%accumulative deformation in one cycle,which can effectively solve the problem of poor interface bonding of the latest interface brought by the last cycle,and thus significantly improve the phenomenon of unstable performance of the ARB-processed sheets. | Haipeng Zheng Ruizhi Wu Legan Hou Jinghuai Zhang Milin Zhang | 2021 | Journal of Magnesium and Alloys2021，9，5： | 4 |

| 6 | Experts consensus on the procedure of dental operative microscope in endodontics and operative dentistry显示文摘The dental operative microscope has been widely employed in the field of dentistry,particularly in endodontics and operative dentistry,resulting in significant advancements in the effectiveness of root canal therapy,endodontic surgery,and dental restoration.However,the improper use of this microscope continues to be common in clinical settings,primarily due to operators’insufficient understanding and proficiency in both the features and established operating procedures of this equipment.In October 2019,Professor Jingping Liang,Vice Chairman of the Society of Cariology and Endodontology,Chinese Stomatological Association,organized a consensus meeting with Chinese experts in endodontics and operative dentistry.The objective of this meeting was to establish a standard operation procedure for the dental operative microscope.Subsequently,a consensus was reached and officially issued.Over the span of about four years,the content of this consensus has been further developed and improved through practical experience. | Bin Liu Xuedong Zhou Lin Yue Benxiang Hou Qing Yu Bing Fan Xi Wei Lihong Qiu Zhengwei Huang Wenwei Xia Zhe Sun Hanguo Wang Liuyan Meng Bin Peng Chen Zhang Shuli Deng Zhaojie Lu Deqin Yang Tiezhou Hou Qianzhou Jiang Xiaoli Xie Xuejun Liu Jiyao Li Zuhua Wang Haipeng Lyu Ming Xue Jiuyu Ge Yi Du Jin Zhao Jingping Liang | 2023 | International Journal of Oral Science2023，15，3： | 0 |
| 7 | Effects of Meteorological Factors on Overwintering Ability,Yield and Quality of Forage Rape显示文摘In order to investigate the effects of meteorological factors on rape overwintering ability,forage yield and quality of rape in the North China plain,Brassia campestris L.and Brassica napus L.were used in this study.The results showed that compared with the B.napus L.varieties,the growth period of B.campestris L.was shortened by 10-15 d,the overwintering rate(WR)increased by 50.6%,and the density after winter(PD)increased by 41.5%.The fresh forage yield(FFY)and dry forage yield(DFY)of the B.campestris L.type significantly increased by 40.9%and 38.1%compared with the B.napus L.type.,respectively,while the forage quality of the B.napus L.type rape was significantly better than that of the B.campestris L.type.Compared with the B.campestris L.type,the crude protein(CP),fat,ash and total fatty acid(TFA)contents of the B.napus L.type of rape increased by 27.6%,42.9%,23.9%and 52.3%,respectively,and the milk productivity(HM),relative forage value(RFV)and relative forage quality(RFQ)increased by 14.0%,16.2%and 42.1%,respectively.The light and heat resources before wintering increased the WR and PD(P<0.05),and were positively correlated with FFY and DFY(P>0.05),and lower temperature during the wintering period led to lower WR(P<0.01).The light and heat resources during the overwintering period and after regreening were negatively correlated with FFY and DFY(P>0.05).The contents of CP,fat and TFA of rape had an extremely significant negative correlation with the temperature and sunshine hours before wintering,but an extremely significant positive correlation with the temperature during the wintering period and after regreening,as well as the sunshine hours and rainfall during the wintering period;and HM had an extremely significant positive correlation with the temperature,sunshine hours and rainfall during the wintering period,while RFV and RFQ were only extremely significantly positively correlated with the maximum temperature and rainfall.In summary,in the North China Plain,for autumn sowing rape,the B.campestris L.type can be selected to improve the wintering rate,and the B.napus L.type should be the main choice to improve the forage quality of rape.Therefore,the B.napus L.variety HYZ62 can be selected for autumn sowing in the North China Plain. | Yao ZHANG Junzhu GE Guangsheng ZHOU Xidong WU Yong an YANG Haipeng HOU Qian LIANG Zhiqi MA | 2021 | Agricultural Biotechnology2021，10，3： | 0 |
| 8 | Permian integrative stratigraphy,biotas,paleogeographical and paleoclimatic evolution of the Qinghai-Tibetan Plateau and its surrounding areas显示文摘The Permian Period was a critical time interval during which various blocks of the Qinghai-Tibetan Plateau have experienced profound and complex paleogeographical changes.The supercontinent Pangea was formed to its maximum during this interval,hampering a global east-to-west trending equatorial warm ocean current.Meanwhile,a semi-closed Tethys Ocean warm pool formed an eastward-opening oceanic embayment of Pangea,and became an engine fostering the evolutions of organisms and environmental changes during the Paleozoic-Mesozoic transition.Stratigraphy and preserved fossil groups have proved extremely useful in understanding such changes and the evolutionary histories of the Qinghai-Tibetan Plateau.Widely distributed Permian deposits and fossils from various blocks of the Qinghai-Tibetan Plateau exhibited varied characteristics,reflecting these blocks’different paleolatitude settings and drifting histories.The Himalaya Tethys Zone south to the Yarlung Zangbo suture zone,located in the northern Gondwanan margin,yields fossil assemblages characterized by cold-water organisms throughout the Permian,and was affliated to those of the Gondwanaland.Most of the exotic limestone blocks within the Yarlung Zangbo suture zone are Guadalupian(Middle Permian)to Early Triassic in age.These exotic limestone blocks bear fossil assemblages that have transitional affinities between the warm Tethys and cold Gondwanan regions,suggesting that they most probably represent seamount deposits in the Neo-Tethys Ocean.During the Asselian to Sakmarian(Cisuralian,also Early Permian),the Cimmerian microcontinents in the northern part of Gondwana preserved glacio-marine deposits of Asselian to Sakmarian,and contained typical Gondwana-type cold-water faunas.By the middle Cisuralian(~290-280 Ma),the Cimmerian microcontinents rifted off from the Gondwanaland,and drifted northward allometrically due to the active magmatism of the Panjal Traps in the northern margin of the Indian Plate.Two slices of microcontinents are discerned as a result of such allometic drifting.The northern Cimmerian microcontinent slice,consisting of South Qiangtang,Baoshan,and Sibuma blocks,drifted relatively quickly,and preserved widespread carbonate deposits and warm-water faunas since Artinskian.By contrast,the southern Cimmerian microcontinent slice,consisting of Lhasa,Tengchong,and Irrawaddy blocks,drifted relatively slowly,and were characterized by widespread carbonate deposits containing warm-water faunas of late Kungurian to Lopingian(Late Permian).As such,these blocks rifted off from the northern Gondwanan margin since at least the Kungurian.Thus,it can be inferred that these blocks were incorperated into the low latitude,warm-water regions later than the northern Cimmerian slice.Such discrepancies in depositional sequences and paleobiogeography imply that the rifting of Cimmerian microcontinents resulted in the formation of both Meso-Tethys and Neo-Tethys oceans during the Cisuralian.By contrast,the North Qiangtang block,because of its further northern paleogeographical position,contains warm-water faunas throughout the whole Permian Period that are affiliated well with the faunas from the South China,Simao,and Indochina blocks.Together,these blocks belonged to the members of the northern Paleo-Tethys Ocean.Thus,an archipelagic paleogeographical framework divided by Paleo-,Meso-,and Neo-Tethys oceans was formed,fostering a global biodiversity centre within the Tethys warm pool.Since most of the allochthonous blocks assembling the Qinghai-Tibetan Plateau were situated in the middle to high latitude regions during the Permian,they preserved most sensitive paleoclimate records of the Late Paleozoic Ice Age(LPIA),the Artinskian global warming event,and the rapid warming event at the end-Permian.Therefore,sedimentological and paleontological records of these blocks are the unique window through which we can understand global evolutions of tectonic movement and paleoclimate,and their impacts on spatiotemporal distributions of comtemporaneous biotas. | Shuzhong SHEN Yichun ZHANG Dongxun YUAN Haipeng XU Qi JU Hua ZHANG Quanfeng ZHENG Mao LUO Zhangshuai HOU | 2024 | Science China Earth Sciences2024，67，4： | 0 |
