| 1 | Research on global change scientific satellites显示文摘Global change now poses a severe threat to the survival and development of mankind.Large-scale,real-time,highly accurate Earth observation from space has become a key technology used to observe global change.China is one of the most influential countries affecting and being affected by global change,yet it has no scientific satellite for global change research so far.Developing global change scientific satellites not only would meet an important demand of China,but also would be a valuable contribution to the world.By analyzing the mechanisms of space-based observation of variables sensitive to global change,this paper explores the concept of global change scientific satellites,and proposes a series of global change scientific satellites to establish a scientific observation system for global environmental change monitoring from space. | GUO HuaDong FU WenXue LI XinWu CHEN Pei LIU Guang LI Zhen WANG Cheng DONG Qing LEI LiPing BAI LinYan LIU QingJie | 2014 | Science China Earth Sciences2014，57，2： | 5 |
| 2 | Multi-label Image Classification via Coarse-to-Fine Attention显示文摘Great efforts have been made by using deep neural networks to recognize multi-label images.Since multi-label image classification is very complicated,many studies seek to use the attention mechanism as a kind of guidance.Conventional attention-based methods always analyzed images directly and aggressively,which is difficult to well understand complicated scenes.We propose a global/local attention method that can recognize a multi-label image from coarse to fine by mimicking how human-beings observe images.Our global/local attention method first concentrates on the whole image,and then focuses on its local specific objects.We also propose a joint max-margin objective function,which enforces that the minimum score of positive labels should be larger than the maximum score of negative labels horizontally and vertically.This function further improve our multi-label image classification method.We evaluate the effectiveness of our method on two popular multi-label image datasets(i.e.,Pascal VOC and MS-COCO).Our experimental results show that our method outperforms state-of-the-art methods. | LYU Fan LI Linyan Victor S.Sheng FU Qiming HU Fuyuan | 2019 | Chinese Journal of Electronics2019，28，6： | 3 |

| 4 | A chromosome-level genome assembly for Erianthus fulvus provides insights into its biofuel potential and facilitates breeding for improvement of sugarcane显示文摘Erianthus produces substantial biomass,exhibits a good Brix value,and shows wide environmental adaptability,making it a potential biofuel plant.In contrast to closely related sorghum and sugarcane,Erianthus can grow in degraded soils,thus releasing pressure on agricultural lands used for biofuel production.However,the lack of genomic resources for Erianthus hinders its genetic improvement,thus limiting its potential for biofuel production.In the present study,we generated a chromosome-scale reference genome for Erianthus fulvus Nees.The genome size estimated by flow cytometry was 937 Mb,and the assembled genome size was 902 Mb,covering 96.26%of the estimated genome size.A total of 35065 proteincoding genes were predicted,and 67.89%of the genome was found to be repetitive.A recent wholegenome duplication occurred approximately 74.10 million years ago in the E.fulvus genome.Phylogenetic analysis showed that E.fulvus is evolutionarily closer to S.spontaneum and diverged after S.bicolor.Three of the 10 chromosomes of E.fulvus formed through rearrangements of ancestral chromosomes.Phylogenetic reconstruction of the Saccharum complex revealed a polyphyletic origin of the complex and a sister relationship of E.fulvus with Saccharum sp.,excluding S.arundinaceum.On the basis of the four amino acid residues that provide substrate specificity,the E.fulvus SWEET proteins were classified as monoand disaccharide sugar transporters.Ortho-QTL genes identified for 10 biofuel-related traits may aid in the rapid screening of E.fulvus populations to enhance breeding programs for improved biofuel production.The results of this study provide valuable insights for breeding programs aimed at improving biofuel production in E.fulvus and enhancing sugarcane introgression programs. | Ling Kui Aasim Majeed Xianhong Wang Zijiang Yang Jian Chen Lilian He Yining Di Xuzhen Li Zhenfeng Qian Yinming Jiao Guoyun Wang Lufeng Liu Rong Xu Shujie Gu Qinghui Yang Shuying Chen Hongbo Lou Yu Meng Linyan Xie Fu Xu Qingqing Shen Amit Singh Karl Gruber Yunbing Pan Tingting Hao Yang Dong Fusheng Li | 2023 | Plant Communications2023，4，4： | 0 |
| 5 | Evaluation and prediction of the status of COVID-19 epidemic prevention and control based on the SEIR+CAQ model显示文摘This paper analyzes the spread of the COVID-19 epidemic in China,establishes a SEIR^(+CAQ)epidemiologic model that classifies the diagnosed population into asymptomatic,mild,and severe,and considers the condition of an isolated population.First of all,we theoretically analyzed the key problems of the disease-free equilibrium,stability,and basic reproduction number of the model.Then,combined with the actual data,the development trend of the epidemic situation is simulated and compared,and the influence of some important parameters is discussed in the model evaluation part.Finally,based on the theoretical analysis and numerical simulation results,we forecast the future development of the COVID-19 epidemic and put forward some reasonable scientific suggestions for the government to formulate a future epidemic prevention policy. | Xingzhi Chen Baodan Tian Feixiang Huang Daiwen Wang Linyan Fu Haoying Xu | 2021 | International Journal of Modeling, Simulation, and Scientific Computing2021，12，3： | 0 |
