| 1 | An improved Landsat Image Mosaic of Antarctica显示文摘A revised Landsat Image Mosaic of Antarctica (LIMA) is presented, using the 1073 multi-band scenes of the original Landsat-7 ETM+ LIMA image collection available at the United States Geological Survey (USGS: http://gffzza64998f73d704ee0hvvkpfqqwpkkx66xv.ffgz.tsg.suse.edu.cn/). Three improvements have been applied during the data processing: (1) DN saturation is adjusted by adopting a linear regression, which has a lower root mean square error than the ratio regression used by LIMA; (2) solar elevation angle is calculated using pixel-level latitude/longitude and the acquisition time and date of the central pixel of the scene, improving slightly upon the bilinear interpolation of the solar elevation angles of scene corners applied in LIMA; and (3) two additional image bands, Band 5 and Band 7, are sharpened using the panchromatic band (Band 8) and a Gram-Schmidt Spectral Sharpening algorithm to more easily distinguish snow, cloud and exposed rocks. The final planetary reflectance product is stored in 16-bit bands to preserve the full radiometric content of the scenes. A comparative statistical analysis among 12 sample regions indicates that the new mosaic has enhanced visual qualities, information entropy, and information content for land cover classification relative to LIMA. | HUI FengMing CHENG Xiao LIU Yan ZHANG YanMei YE YuFang WANG XianWei LI Zhan WANG Kun ZHAN ZhiFei GUO JianHong HUANG HuaBing LI XiuHong GUO ZiQi GONG Peng | 2013 | Science China Earth Sciences2013，56，1： | 4 |
| 2 | Low sample volume origami-paper-based graphene-modified aptasensors for label-free electrochemical detection of cancer biomarker-EGFR显示文摘In this work,an electrochemical paper-based aptasensor was fabricated for label-free and ultrasensitive detection of epidermal growth factor receptor(EGFR)by employing anti-EGFR aptamers as the bio-recognition element.The device used the concept of paper-folding,or origami,to serve as a valve between sample introduction and detection,so reducing sampling volumes and improving operation convenience.Amino-functionalized graphene(NH 2-GO)/thionine(THI)/gold particle(AuNP)nanocomposites were used to modify the working electrode not only to generate the electrochemical signals,but also to provide an environment conducive to aptamer immobilization.Electrochemical characterization revealed that the formation of an insulating aptamer–antigen immunocomplex would hinder electron transfer from the sample medium to the working electrode,thus resulting in a lower signal.The experimental results showed that the proposed aptasensor exhibited a linear range from 0.05 to 200 ngmL^(−1)(R^(2)=0.989)and a detection limit of 5pgmL^(−1) for EGFR.The analytical reliability of the proposed paper-based aptasensor was further investigated by analyzing serum samples,showing good agreement with the gold-standard enzyme-linked immunosorbent assay. | Yang Wang Shuai Sun Jinping Luo Ying Xiong Tao Ming Juntao Liu Yuanyuan Ma Shi Yan Yue Yang Zhugen Yang Julien Reboud Huabing Yin Jonathan MCooper Xinxia Cai | 2020 | Microsystems & Nanoengineering2020，6，1： | 2 |

| 6 | Influence of Artificial Cofferdam and Spartina alterniflora Expansion on Evolution of Suaeda salsa Marsh in Yancheng Coastal Wetland of East China显示文摘Suaeda salsa is an important local species in the intertidal beach of the Western Pacific coast. However,under the artificial cofferdam and Spartina alterniflora expansion,Suaeda marsh has degraded seriously. Therefore,using Yancheng Nature Reserve as a case study area,taking ETM+images in 2000,2006 and 2011 as the basic data sources,we revealed the evolution characteristics of Salsa marsh which was impacted. The research results are as follows. From 2000 to 2011,Salsa marsh area in the artificial area tempestuously degraded,decreasing by 87. 158%,more than 22% than those in the natural area. The landscape was fragmentized. Landscape polymerization degree index dropped from 95. 780 to 65. 455,more than 16% than those in the natural area. The mean patch area fell down to 21. 429 ha from 389. 333 ha,more than 11% that in the natural area. Compared to the steady change in natural conditions,the area was reduced by 118. 167 ha/a from 2000 to 2006,while during 2006-2011,it was only 51. 500 ha/a in artificial area. As for spatial change of landscape,in artificial area,the Salsa marsh centroid moved forward to the southeast with 666. 350 m,but that in natural area moved forward to the north with 1 042. 710 m from 2000 to 2006. From 2006 to 2011,the centroid moved forward to east and north respectively. Artificial cofferdam transformed the area into freshwater ecosystem,and meanwhile the freshwater was beneficial to Reed marsh. During 2000 to 2006,in the artificial area,539 ha Salsa marsh controlled by cofferdam transferred into reed marsh and aquaculture ponds,of which the transformation rate was nearly 4% higher than that in natural area. From 2006 to 2011,178 ha Salsa marsh was transferred into reed marsh,the transformation rate was 20% higher than that in natural area. With rapid spreading and strong competition of Spartina species,the coastal wetland has formed the pattern of ' Salsa – Spartina marshes'. From 2000 to 2006,in artificial area,15. 24% of Salsa marsh was transferred into Spartina marsh,of which the transformation rate was13% higher than that in natural area. And from 2006 to 2011,30. 07% Salsa marsh was replaced by the Spartina marsh in artificial area,the rate was almost 10% higher than that in the natural area. | Shuang HAN Yan ZHEN Yufeng LI Huabing ZHANG | 2018 | Asian Agricultural Research2018，10，4： | 1 |
| 7 | Telomere-to-telomere assembly of cassava genome reveals the evolution of cassava and divergence of allelic expression显示文摘Cassava is a crucial crop that makes a significant contribution to ensuring human food security.However,high-quality telomere-totelomere cassava genomes have not been available up to now,which has restricted the progress of haploid molecular breeding for cassava.In this study,we constructed two nearly complete haploid resolved genomes and an integrated,telomere-to-telomere gap-free reference genome of an excellent cassava variety,‘Xinxuan 048’,thereby providing a new high-quality genomic resource.Furthermore,the evolutionary history of several species within the Euphorbiaceae family was revealed.Through comparative analysis of haploid genomes,it was found that two haploid genomes had extensive differences in linear structure,transcriptome features,and epigenetic characteristics.Genes located within the highly divergent regions and differentially expressed alleles are enriched in the functions of auxin response and the starch synthesis pathway.The high heterozygosity of cassava‘Xinxuan 048’leads to rapid trait segregation in the first selfed generation.This study provides a theoretical basis and genomic resource for molecular breeding of cassava haploids. | Xin-Dong Xu Ru-Peng Zhao Liang Xiao Liuying Lu Min Gao Yu-Hong Luo Zu-Wen Zhou Si-Ying Ye Yong-Qing Qian Bing-Liang Fan Xiaohong Shang Pingli Shi Wendan Zeng Sheng Cao Zhengdan Wu Huabing Yan Ling-Ling Chen Jia-Ming Song | 2023 | Horticulture Research2023，10，11： | 0 |
