| 1 | First dark matter search results from the PandaX-Ⅰ experiment显示文摘We report on the first dark-matter(DM)search results from PandaX-I,a low threshold dual-phase xenon experiment operating at the China JinPing Underground Laboratory.In the 37-kg liquid xenon target with 17.4 live-days of exposure,no DM particle candidate event was found.This result sets a stringent limit for low-mass DM particles and disfavors the interpretation of previously-reported positive experimental results.The minimum upper limit,3.7×10-44cm2,for the spin-independent isoscalar DM-particle-nucleon scattering cross section is obtained at a DM-particle mass of 49 GeV/c2at 90%confidence level. | XIAO MengJiao XIAO Xiang ZHAO Li CAO XiGuang CHEN Xun CHEN YunHua CUI XiangYi FANG DeQing FU ChangBo GIBONI Karl L.

| 3 | Identification and fine-mapping of quantitative trait loci(QTL) conferring rice false smut resistance in rice显示文摘Rice false smut(RFS) is a rice fungal disease caused by the biotrophic fungus Ustilaginoidea virens(Cooke) Takahashi. The pathogenic fungus specifically infects rice spikelets at the booting stage and coverts the infected spikelets into false smut balls consisting of hyphae and chlamydospores(Ashizawa et al., 2012);Sun et al. | Yifeng Huang Kaixuan Cui Zhen Zhang Rongyao Chai Hongguang Xie Jianyao Shou Junru Fu Guolin Li Jiyun Liu Shuangqing Wu Guochang Sun Jianfu Zhang Yiwen Deng Zuhua He | 2023 | Journal of Genetics and Genomics2023，50，4： | 1 |
| 4 | Advancing knowledge of plasma spraying coatings for Li||Sb-Sn liquid metal batteries by X-ray micro-CT显示文摘The performance of Li||Sb-Sn liquid metal batteries(LMBs) is hindered by the corrosion of the Sb-Sn cathode on its current collector. Herein, a uniform, dense, and low-oxidized W coating was prepared by plasma spraying, which can effectively resist the corrosion of the cathode and improve the cycle stability of the Li||Sb-Sn LMBs. For the first time, micro-CT nondestructive inspection is applied in the field of LMBs. The corrosion micromorphology and composition evolution of the SS304 matrix and Sb-Sn cathode with or without the plasma-sprayed W coating is obtained without disassembling the battery, which proves that the W coating can effectively protect the SS304 matrix. Our autonomous new LMB device for nondestructive inspection is universal and can be applied to different LMBs systems for advancing knowledge of corrosion mechanism and protection. This work guarantees the ability to directly visualize the inner critical positions in three dimensions and fills the knowledge gap in the field of LMB detection technology. | Kaixuan Cui Ping Li Wang Zhao Chunrong Liu Qi Wan Shengwei Li Xuanhui Qu | 2023 | Chinese Chemical Letters2023，34，7： | 0 |
| 5 | A review of occluded objects detection in real complex scenarios for autonomous driving显示文摘Autonomous driving is a promising way to future safe,efficient,and low-carbon transportation.Real-time ac-curate target detection is an essential precondition for the generation of proper following decision and control signals.However,considering the complex practical scenarios,accurate recognition of occluded targets is a major challenge of target detection for autonomous driving with limited computational capability.To reveal the overlap and difference between various occluded object detection by sharing the same available sensors,this paper presents a review of detection methods for occluded objects in complex real-driving scenarios.Considering the rapid development of autonomous driving technologies,the research analyzed in this study is limited to the recent five years.The study of occluded object detection is divided into three parts,namely occluded vehicles,pedes-trians and traffic signs.This paper provided a detailed summary of the target detection methods used in these three parts according to the differences in detection methods and ideas,which is followed by the comparison of advantages and disadvantages of different detection methods for the same object.Finally,the shortcomings and limitations of the existing detection methods are summarized,and the challenges and future development prospects in this field are discussed. | Jiageng Ruan Hanghang Cui Yuhan Huang Tongyang Li Changcheng Wu Kaixuan Zhang | 2023 | Green Energy and Intelligent Transportation2023，2，3： | 0 |
| 6 | Blood compatible heteratom-doped carbon dots for bio-imaging of human umbilical vein endothelial cells显示文摘Carbon dots have unique advantages in biological applications owing to their excellent optical prope rties.However,the biosafety evaluation of carbon dots has limitations owing to cytotoxicity in vitro,and the re is little pre-safety evaluation before in vivo and clinical applications.Whether the carbon dots are or not suitable for applications in vivo,evaluation analysis can be made based on hemolysis and changes in erythrocyte morphology.In this work,a green fluorescent N,S-doped carbon dots(N,S-CDs)were obtained by hydrothermal method,tobias acid,and m-phenylenediamine as precursors.N,S-CDs not only possessed excellent dispersibility,uniform particle size,high quantum yield(37.2%)and stable photoluminescence property but also retain their photostability and stro ng fluorescence intensity in the acid/alkaline solutions,different ionic strengths(NaCl)and under 365 nm UV illumination.Moreove r,the N,S-CDs displayed low cytotoxicity and high cellular uptake efficiency in human umbilical vein endothelial cells(HUVEC)and excellent blood compatibility to the erythrocyte.It is foreseeable that N,S-CDs could be further studied as a promising biological imaging agent in vivo. | Jian Zhong Xinmian Chen Miaoran Zhang Chaoxin Xiao Lulu Cai Waleed Ali Khan Kaixuan Yu Jiayi Cui Lin He | 2020 | Chinese Chemical Letters2020，31，3： | 0 |
| 7 | Pseudotime Ordering Single-Cell Transcriptomic ofβCells Pancreatic Islets in Health and Type 2 Diabetes显示文摘βcells are defined by the ability to produce and secret insulin.Recent studies have evaluated that human pancreaticβcells are heterogeneous and demonstrated the transcript alterations ofβcell subpopulation in diabetes.Single-cell RNA sequence(scRNA-seq)analysis helps us to refine the cell types signatures and understand the role of theβcells during metabolic challenges and diseases.Here,we construct the pseudotime trajectory ofβcells from publicly available scRNA-seq data in health and type 2 diabetes(T2D)based on highly dispersed and highly expressed genes using Monocle2.We identified three major states including 1)Normal branch,2)Obesity-like branch and 3)T2D-like branch based on biomarker genes and genes that give rise to bifurcation in the trajectory.βcell function-maintain-related genes,insulin expression-related genes,and T2D-related genes enriched in three branches,respectively.Continuous pseudotime spectrum might suggest thatβcells transition among different states.The application of pseudotime analysis is conducted to clarify the different cell states,providing novel insights into the pathology ofβcells in T2D. | Kaixuan Bao Zhicheng Cui Hui Wang Hui Xiao Ting Li Xingxing Kong Tiemin Liu | 2021 | Phenomics2021，1，5： | 0 |
| 8 | Characterization and diversity of magnetotactic bacteria from sediments of Caroline Seamount in the Western Pacific Ocean显示文摘Magnetotactic bacteria(MTB)are a group of microorganisms capable of orientating and swimming along magnetic fields because they contain intracellular biomineralized magnetosomes composed of magnetite(Fe 3 O 4)or/and greigite(Fe_(3)S_(4)).They are ubiquitous in freshwater,brackish,and marine habitats,and are cosmopolitan in distribution.However,knowledge of their occurrence and distribution in seamount ecosystems is limited.We investigated the diversity and distribution of MTB in the Caroline Seamount(CM4).The abundance of living MTB in 12 stations in depth varying from 90 to 1545 m was 1.1×10^(3)-43.7×10^(3) inds./dm 3.Despite diverse shapes of MTB observed,magnetotactic cocci were the dominant morphotype and could be categorized into two types:1)typical cocci that appeared to have peritrichous fl agella;and 2)those characterized by having a drop-shaped form and one bundle of fl agella located at the thin/narrow end of the cell.Transmission electron microscopy(TEM)analysis revealed that the magnetosomes formed by those magnetotactic cocci are magnetite(Fe 3 O 4)with octahedral crystal habit.A total of 41 operational taxonomic units(OTUs)of putative MTB(2702 reads)were acquired from nine stations,based on high-throughput sequencing.Of these,40 OTUs belonged to the Proteobacteria phylum and one belonged to the Nitrospirae phylum.We found apparent connectivity between the MTB populations on the Caroline and Kexue(Science in Chinese)seamounts,although the diversity of MTB on Caroline was much richer than on the Kexue Seamount.Our results imply that the unique topography of seamounts and other as-yet unclear environmental factors could lead to evolution of different fl agella arrangements in magnetotactic cocci,and the occurrence of octahedral magnetite magnetosomes. | Kaixuan CUI Wenyan ZHANG Jia LIU Cong XU Yicong ZHAO Si CHEN Hongmiao PAN Tian XIAO Long-Fei WU | 2021 | Journal of Oceanology and Limnology2021，39，6： | 0 |
| 9 | Observations on a magnetotactic bacteria-grazing ciliate in sediment from the intertidal zone of Huiquan Bay,China显示文摘Magnetotactic bacteria(MTB)are a group of prokaryotes having the ability to orient and swim along geomagnetic field lines because they contain intracellular magnetosomes that are synthesized through a biomineralization process.Magnetosomes have recently also been found in unicellular eukaryotes,which are referred to as magnetically responsive protists(MRPs).The magnetosomes have three origins in MRPs.In this study,we characterized a MTB-grazing ciliated MRP that was magnetically collected from intertidal sediment of Huiquan Bay,Qingdao,China.Based on 18S rRNA gene sequence analysis,the ciliated MRP was tentatively identified as Uronemella parafi lificum HQ.Using transmission electron microscopy,we observed that magnetosomes having 2-3 shapes were randomly distributed within this ciliate.Energydispersive X-ray spectroscopy and high-resolution transmission electron microscopy images of the magnetosomes were consistent with them being composed of magnetite.Magnetosomes having the same shape and mineral composition were also detected in MTB that occurred in the same environment as the ciliated MRP.Statistical analysis showed that the size and shape of the magnetosomes in the ciliated MRP were similar to those in MTB.The results suggest that this ciliated MRP can graze,ingest,and digest various types of MTB.It is certainly worth noting that this is the first record of MRPs in Asian aquatic sediment and suggesting they might be widely distributed.These results also support the assertion that MRPs probably contribute to the ecological cycles of iron,and expand possibilities for research into the mechanism of magnetoreception in eukaryotes. | Si CHEN Kaixuan CUI Wenyan ZHANG Yicong ZHAO Tian XIAO Hongmiao PAN Wuchang ZHANG Long-Fei WU | 2021 | Journal of Oceanology and Limnology2021，39，6： | 0 |
| 10 | Data driving design of high-entropy alloys for lightweight and dynamic applications显示文摘The topic of high-entropy alloys is one of the focus for both physics and materials research.High-entropy alloys were usually defined as solid solution alloys,while the solid solution is different from the traditional terminal solid solution,because the solid solution without solvent element is the dominant one.The discovery of high-entropy alloys greatly extended the composition space and the possibility of creating unique micro-and nano-level structures,which can meet the demands of lightweight and dynamic applications.The relationship between the phases and the parameters for the high-entropy alloys is rather complex.The data driving design can screen the specific high-entropy alloys.The correlation between the composition and properties of highentropy alloys can be discovered by material genetic engineering and data science. | Kaixuan Cui Junwei Qiao Peter KLiaw Yong Zhang | 2024 | Science China(Physics,Mechanics & Astronomy)2024，67，2： | 0 |
