| 1 | Fusing Fixed and Hint Landmarks on Crowd Paths for Automatically Constructing Wi-Fi Fingerprint Database显示文摘In typical Wi-Fi based indoor positioning systems employing fingerprint model,plentiful fingerprints need to be trained by trained experts or technician,which extends labor costs and restricts their promotion.In this paper,a novel approach based on crowd paths to solve this problem is presented,which collects and constructs automatically fingerprints database for anonymous buildings through common crowd customers.However,the accuracy degradation problem may be introduced as crowd customers are not professional trained and equipped.Therefore,we define two concepts:fixed landmark and hint landmark,to rectify the fingerprint database in the practical system,in which common corridor crossing points serve as fixed landmark and cross point among different crowd paths serve as hint landmark.Machinelearning techniques are utilized for short range approximation around fixed landmarks and fuzzy logic decision technology is applied for searching hint landmarks in crowd traces space.Besides,the particle filter algorithm is also introduced to smooth the sample points in crowd paths.We implemented the approach on off-the-shelf smartphones and evaluate the performance.Experimental results indicate that the approach can availably construct WiFi fingerprint database without reduce the localization accuracy. | HUANG Zhengyong XIA Jun YU Hui GUAN Yunfeng GAN Xiaoying LIU Jing | 2015 | China Communications2015，12，1： | 2 |
| 2 | Super broadband absorbing hierarchical CoFe alloy/porous carbon@carbon nanotubes nanocomposites derived from metal-organic frameworks显示文摘The exploitation of electromagnetic wave absorption(EMA) materials has attracted ever-increasing attention,not only because electromagnetic wave(EMW) originated from overuse of electronic products has threatened human' health seriously,but also because EMA materials can effectively protect radar stealth from being detected.However,it is still a challenge to obtain broadband and efficient EMA materials to satisfy practical applications.In this work,we developed a series of hierarchical CoFe alloy/porous carbon@carbon nanotubes(CoFe/PC@CNTs) nanocomposites through revising the proportion of Fe^(2+) in the metal-organic frameworks(MOFs)(CoFe-ZIF) precursor and one-step simple pyrolysis process.The cross deposition between CoFe alloy,carbon nanotubes(CNTs),and porous carbon(PC) formed a double conductive network,favoring for achieving excellent EMA property.Surprisingly,when the filler mass ratio is only 10 wt%,the optimized CoFe/PC@CNTs nanocomposites display the best EMA capability,whose minimum reflection loss(RL_(min)) value is-68.94 dB at 13.69 GHz and the effective absorption band(EAB,<-10 dB) reaches up 9.14 GHz with a matching thickness of 2.63 mm.In addition,the largest EAB can achieve up to 11 GHz(3.35-14.35 GHz) during all matching thicknesses.The splendid EMA performance benefits the favorable dielectric loss provided by the double conductive network,the good magnetic loss benefited from the evenly distributed CoFe alloy,the excellent impedance matching,rich transmission paths,and multiple polarization.Therefore,such EMA materials with super broadband absorbing provide desirable candidates for lightweight and high-efficient microwave absorbers. | Siyao Guo Yunfeng Bao Ying Li Hailong Guan Dongyi Lei Tiejun Zhao Baomin Zhong Zhihong Li | 2022 | Journal of Materials Science & Technology2022，，23： | 2 |
| 3 | Endothelial METRNL determines circulating METRNL level and maintains endothelial function against atherosclerosis显示文摘METRNL is a recently identified secreted protein with emerging functions.This study is to find major cellular source of circulating METRNL and to determine METRNL novel function.Here,we show METRNL is abundant in human and mouse vascular endothelium and released by endothelial cells using endoplasmic reticulum-Golgi apparatus pathway.By creating endothelial cell-specific Metrnl knockout mice,combined with bone marrow transplantation to produce bone marrow-specific deletion of Metrnl,we demonstrate that most of circulating METRNL(approximately 75%)originates from the endothelial cells.Both endothelial and circulating METRNL decrease in atherosclerosis mice and patients.By generating endothelial cell-specific Metrnl knockout in apolipoprotein E-deficient mice,combined with bone marrow-specific deletion of Metrnl in apolipoprotein E-deficient mice,we further demonstrate that endothelial METRNL deficiency accelerates atherosclerosis.Mechanically,endothelial METRNL deficiency causes vascular endothelial dysfunction including vasodilation impairment via reducing eNOS phosphorylation at Ser1177 and inflammation activation via enhancing NFκB pathway,which promotes the susceptibility of atherosclerosis.Exogenous METRNL rescues METRNL deficiency induced endothelial dysfunction.These findings reveal that METRNL is a new endothelial substance not only determining the circulating METRNL level but also regulating endothelial function for vascular health and disease.METRNL is a therapeutic target against endothelial dysfunction and atherosclerosis. | Sili Zheng Zhiyong Li Jie Song Pin Wang Jian Xu Wenjun Hu Yi Shi Qi Qi Zhuwei Miao Yunfeng Guan Chaoyu Miao | 2023 | Acta Pharmaceutica Sinica B2023，13，4： | 2 |

| 13 | Reversed configuration of photocatalyst to exhibit improved properties of basic processes compared to conventional one显示文摘Performances of semiconductor photocatalysts are integrally determined by efficiencies of basic processes such as light absorption,charge separation and surface catalysis,but conventional configurations of photocatalysts normally suffers from the competition of light absorption originating from cocatalyst deposition and limited interface charge separation between the photocatalyst and cocatalyst.Herein we give the first proof-of-concept illustration that a reversed configuration of photocatalysts with a core/shell structure of microsized Mo2N cocatalysts and nanosized CdS photocatalysts,which exhibits superior solar hydrogen production to the conventional configuration with nanosized Mo2N cocatalysts deposited on the surface of CdS photocatalysts.It is revealed that the reversed configuration outperforms the conventional one in all areas of light absorption,charge separation and surface catalysis.Strikingly,the special core/shell structure introduced here can well avoid the competition of light absorption by cocatalysts and make an effective confinement effect to promote the surface catalysis of Mo2N.Our finding provides an alternative strategy to improve performances of photocatalysts. | Juhong Lian Yu Qi Yunfeng Bao Zixi Yin Yang Zhang Nengcong Yang Naijia Guan Shengye Jin Landong Li Fuxiang Zhang | 2020 | Science China Chemistry2020，63，6： | 1 |

| 17 | Mapping a stable adult-plant stripe rust resistance QTL on chromosome 6AL in Chinese wheat landrace Yibinzhuermai显示文摘Stripe rust,caused by Puccinia striiformis f.sp.tritici(Pst),is one of the most important diseases threatening the yield and stability of wheat production in China and many other countries.Identification and utilization of new genes for durable stripe rust resistance are important for ongoing control of this disease.The objectives of this study were to identify quantitative trait loci(QTL)associated with adult-plant stripe rust resistance in the Chinese wheat landrace Yibinzhuermai(YBZR)and to provide wheat breeders with new sources of potentially durable resistance.A total of 117 recombinant inbred lines(RILs)(F5:8)derived from a cross between YBZR and highly susceptible cultivar Taichung 29(TC29)were assessed for stripe rust severity in field experiments at Wenjiang in 2016 and 2017 and Chongzhou in 2016,2017,2018,and 2019 in Sichuan following inoculation with a mixture of current Pst races.The RILs were genotyped using the Wheat55K single nucleotide polymorphism(SNP)array.Three QTL were identified on chromosome arms 6AL,5BL and 7DS.QYr.YBZR-6AL and QYr.YBZR-7DS conferred major effects in all field environments,explaining 10.6%to 14.7%and 11.5%to 21.2%of phenotypic variation,respectively.The QTL on 5BL and 7DS likely correspond to previously known QTL,whereas QYr.YBZR-6AL is probably novel.Haplotype analysis revealed that the resistance allele at QYr.YBZR-6AL was present in 2.8%of 324 Chinese wheat landraces.SNP markers closely linked with QYr.YBZR-6AL were converted to kompetitive allele-specific PCR markers and validated in the RIL population and a subset of 92 wheat cultivars.QYr.YBZR-6AL and its markers should be useful in breeding programs to improve the level and durability of stripe rust resistance. | Mei Deng Li Long Yukun Cheng Fangjie Yao Fangnian Guan Yuqi Wang Hao Li Zhien Pu Wei Li Qiantao Jiang Yuming Wei Jian Ma Houyang Kang Pengfei Qi Jirui Wang Youliang Zheng Yunfeng Jiang Guoyue Chen | 2022 | The Crop Journal2022，10，4： | 0 |
| 18 | MHC class Ⅱ in renal tubules plays an essential role in renal fibrosis显示文摘Immunomodulation has been considered a potential therapeutic approach for chronic kidney disease(CKD).Although it has been previously reported that CD4+T cells contribute to the development of renal fibrosis after UUO,the role of MHC class Ⅱ(MHCII)in UUO-induced renal fibrosis remains largely uncharacterized.The present study reports that the expressions of MHCII molecules in renal cortical tubules are upregulated in a mouse unilateral ureter obstruction(UUO)model.Global or renal tubule-specific ablation of MHCII significantly alleviates renal fibrosis following UUO.Additionally,renal expression of profibrotic genes showcased consistent reduction in both MHCII gene deficient mouse lines.These results demonstrate that renal tubular MHCII plays an important role in pathogenesis of renal fibrosis. | Yunfeng Zhou Zhaokang Luo Chenghui Liao Rong Cao Zain Hussain Jie Wang Yeting Zhou Tie Chen Jie Sun Zhong Huang Baohua Liu Xiaoyan Zhang Youfei Guan Tuo Deng | 2021 | Cellular & Molecular Immunology2021，18，11： | 0 |
| 19 | Fine mapping and transcriptome sequencing reveal candidate genes conferring all-stage resistance to stripe rust on chromosome arm 1AL in Chinese wheat landrace AS1676显示文摘Stripe rust, caused by Puccinia striiformis f. sp. tritici(Pst), threatens wheat production worldwide, and resistant varieties tend to become susceptible after a period of cultivation owing to the variation of pathogen races. In this study, a new resistance gene against Pst race CYR34 was identified and predicted using the descendants of a cross between AS1676, a highly resistant Chinese landrace, and Avocet S, a susceptible cultivar. From a heterozygous plant from a F7recombinant inbred line(RIL) population lacking the Yr18 gene, a near-isogenic line(NIL) population was developed to map the resistance gene. An allstage resistance gene, YrAS1676, was identified on chromosome arm 1AL via bulked-segregant exomecapture sequencing. By analyzing a large NIL population consisting of 6537 plants, the gene was further mapped to the marker interval between KA1A_485.36 and KA1A_490.13, spanning 485.36–490.13 Mb on1AL. A total of 66 annotated genes have been reported in this region. To characterize and predict the candidate gene(s), an RNA-seq was performed using NIL-R and NIL-S seedlings 3 days after CYR34 inoculation. Compared to NIL-S plants, NIL-R plants showed stronger immune reaction and higher expression levels of genes encoding pathogenesis-associated proteins. These differences may help to explain why NIL-R plants were more resistant to Pst race CYR34 than NIL-S plants. By combining fine-mapping and transcriptome sequencing, a calcium-dependent protein kinase gene was finally predicted as the potential candidate gene of YrAS1676. This gene contained a single-nucleotide polymorphism. The candidate gene was more highly expressed in NIL-R than in NIL-S plants. In field experiments with Pst challenge,the YrAS1676 genotype showed mitigation of disease damage and yield loss without adverse effects on tested agronomic traits. These results suggest that YrAS1676 has potential use in wheat stripe rust resistance breeding. | Xiu Yang Yunfeng Jiang Xianghai Yu Haipeng Zhang Yuqi Wang Fangnian Guan Li Long Hao Li Wei Li Qiantao Jiang Jirui Wang Yuming Wei Jian Ma Houyang Kang Pengfei Qi Qiang Xu Meng Deng Yazhou Zhang Youliang Zheng Yonghong Zhou Guoyue Chen | 2023 | The Crop Journal2023，11，5： | 0 |
