| 1 | Changing Rural Development Inequality in Jilin Province, Northeast China显示文摘Rural development inequality is an important practical issue during the course of full establishment of a ′moderately well-off society′ in modern China,and the objective understanding and evaluation of the status and regional inequality of rural development can provide scientific basis for ′building a new countryside′ and coordination development of rural-urban regions.Based on the county-level data of 2000,2005 and 2009,this paper examines the rural development inequality of Jilin Province in Northeast China by establishing a rural development index.The spatio-temporal dynamic patterns and domain factors are discussed by using the method of exploratory spatial data analysis and multi-regression model.The results are shown as follows.Firstly,most of the counties were in lower development level,which accounted for 58.3%,62.5% and 66.7% of the total counties in 2000,2005 and 2009,respectively.The characteristics of spatial inequality were very obvious at county level.For example,rural development level of Changchun Proper and the proper of seven prefecture-level cities were much higher than that of the surrounding regions.The counties in the eastern and northern Jilin Province were the lowest regions of rural development level,while the middle counties were the rapid growth areas in rural economy.Secondly,Moran′s I of rural development index(RDI) was 0.01,–0.16 and –0.06 in 2000,2005 and 2009,respectively,which indicated that spatial agglomeration of RDI was not obvious in Jilin Province,and took on the characteristic of random distribution.The counties of both the units and its adjacent units have higher development level(HH) were transferred from the western areas to the eastern areas,while the countries of both the units and its adjacent units have lower development level(LL) were diffused from the eastern to middle and western Jilin Province.Finally,the result of multi-regression analysis showed that the improvement of agricultural production condition,development of agricultural economics and the adjustment of industrial structure were the domain factors affecting rural development inequality of Jilin Province in the later ten years. | CHENG Yeqing WANG Yanfei WANG Zheye LUO Xiaolong | 2013 | Chinese Geographical Science2013，23，5： | 9 |
| 2 | Acetate-assistant efficient cation-exchange of halide perovskite nanocrystals to boost the photocatalytic CO_(2) reduction显示文摘The judicious implantation of active metal cations into the surface of semiconductor nanocrystal(NC)through cation-exchange is one of the facile and viable strategies to enhance the activity of catalysts for photocatalytic CO_(2)reduction,by shortening the transfer pathway of photogenerated carriers and increasing the active sites simultaneously.However,cation-exchange is hard to achieve for halide perovskite NCs owing to the stable octahedron of[PbX6]4−with strong interaction between halogen and lead.Herein,we report a facile method to overcome this obstacle by replacing partial Br−with acetate(Ac−)to generate CsPbBr_(3) NC(coded as CsPbBr_(3−x)Ac_(x)).A small amount of Ac−instead of Br−does not change the crystal structure of halide perovskite.Owing to the weaker interaction between acetate and lead in comparison with bromide,the corresponding octahedron structure containing acetate in CsPbBr_(3−x)Ac_(x) can be easily opened to realize efficient cation-exchange with Ni^(2+) ions.The resulting high loading amount of Ni^(2+) as active site endows CsPbBr_(3−x)Ac_(x) with an improved performance for photocatalytic CO_(2)reduction under visible light irradiation,exhibiting a significantly increased CO yield of 44.09μmol·g^(−1)·h^(−1),which is over 8 and 3 times higher than those of traditional pristine CsPbBr_(3) and nickel doped CsPbBr_(3) NC,respectively.This work provides a critical solution for the efficient metal doping of low-cost halide perovskite NCs to enhance their photocatalytic activity,promoting their practical applications in the field of photocatalysis. | Jialin Cheng Yanfei Mu Liyuan Wu Zhaolei Liu Ke Su Guangxing Dong Min Zhang Tongbu Lu | 2022 | Nano Research2022，15，3： | 3 |

| 4 | Synergetic Improvement of Interlaminar Fracture Toughness in Carbon Fiber/Epoxy Composites Interleaved with PES/PEK‑C Hybrid Nanofiber Veils显示文摘In this study,two types of soluble thermoplastic resins were added to epoxy resin at a fixed weight ratio to prepare a three-phase cast body.The cast was then manufactured into hybrid nanofiber as interleaves for interlaminar toughening of carbon fiber/epoxy resin(CF/EP)composites using a co-solvent method.The results revealed that when the hybrid components reached 15 wt%,Polyethersulfone(PES)and polyaryletherketone cardo(PEK-C)exhibited the best synergistic toughening effect,and the fracture toughness increased by 99.8%and 39.8%,respectively,compared with the reference or the same proportion of the single PES toughened sample.We used PES/PEK-C hybrid nanofibers with an areal density of 19.2 g per square meter(gsm)as composite toughening layers.Apart from the lack of significant influence of PES nanofiber on CF/EP composites,the interlaminar fracture toughness of mode I and mode II layers increased by 88.3%and 46.9%,respectively,compared to the reference sample.Scanning Electron Microscopy of the fracture surface and cross-section micromorphology of the laminate displayed that the thermoplastic microspheres of different sizes contribute differently to crack resistance:PEK-C consumes more energy due to the debonding and extraction of microspheres and resin,whereas the presence of the PES phase can induce more plastic deformation and crack deflection. | Jinli Zhou Chenyu Zhang Chao Cheng Ming Wang Zhihui Yang Yanfei Yang Hongying Yang Muhuo Yu | 2022 | Advanced Fiber Materials2022，4，5： | 3 |
| 5 | Understanding divergent domestication traits from the whole-genome sequencing of swamp-and river-buffalo populations显示文摘Domesticated buffaloes have been integral to rice-paddy agro-ecosystems formillennia,yet relatively little is known about the buffalo genomics.Here,we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals(132 swamp buffaloes and 98 river buffaloes)sampled from across Asia and Europe.Beyond the many actionable insights that our study revealed about the domestication,basic physiology and breeding of buffalo,we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior,digestion metabolism,strengths and milk production. | Xier Luo Yu Zhou Bing Zhang Yi Zhang Xiaobo Wang Tong Feng Zhipeng Li Kuiqing Cui Zhiqiang Wang Chan Luo Hui Li Yanfei Deng Fenghua Lu Jianlin Han Yongwang Miao Huaming Mao Xiaoyan Yi Cheng Ai Shigang Wu Alun Li Zhichao Wu Zijun Zhuo Do Da Giang Bikash Mitra Mohammad Farhad Vahidi Shahid Mansoor Sahar Ahmed Al-Bayatti Eka Meutia Sari Neena Amatya Gorkhali Sigit Prastowo Laiba Shafique Guoyou Ye Qian Qian Baoshan Chen Deshun Shi Jue Ruan Qingyou Liu | 2020 | National Science Review2020，7，3： | 3 |

| 10 | Cyber Hierarchy Multiscale Integrated Energy Management of Intelligent Hybrid Electric Vehicles显示文摘The full-lifespan management concept provides a new pathway to seeking solutions from macro-application scenarios to micro-mechanism levels.This paper presents a cyber hierarchy multiscale optimal control method for multiple intelligent hybrid vehicles to fully release the potentials of vehicle components while guaranteeing driving safety and stability.It can be generally divided into the cyber intelligent driving system on the cyber-end and the intelligent vehicle system on the vehicle-end.On the cyber-end,the state information of the surrounding vehicles is transmitted via the Vehicle-to-Everything structure and further processed in the cloud platform to generate future driving behaviors based on a car-following theory.On the vehicle-end,an optimized control sequence for vehicle components at micro-levels is derived by incorporating a physics-informed neural network model for battery health prediction.The results show that global optimization needs high coupling between the macro-and micro-physical processes.By introducing the genetic algorithm for time smoothing,the improved driving strategy is capable of macro-and micro-coupling,and thus improves the controllable performance in time series.Moreover,this method spans the complexity of space,time,and chemistry,enhances the interpretation performance of machine learning,and slows down the battery aging in the process of multiscale optimization. | Yanfei Gao Shichun Yang Xibo Wang Wei Li Qinggao Hou Qin Cheng | 2022 | Automotive Innovation2022，5，4： | 0 |

| 12 | Disruption of the autism-related gene Pak1 causes stereocilia disorganization,hair cell loss,and deafness in mice显示文摘Several clinical studies have reported that hearing loss is correlated with autism in children.However,little is known about the underlying mechanism between hearing loss and autism.p21-activated kinases(PAKs)are a family of serine/threonine kinases that can be activated by multiple signaling molecules,particularly the Rho family of small GTPases.Previous studies have shown that Pak1 mutations are associated with autism.In the present study,we take advantage of Pak1 knockout(Pak1a/a)mice to investigate the role of PAK1 in hearing function.We find that PAK1 is highly expressed in the postnatal mouse cochlea and that PAK1 deficiency leads to hair cell(HC)apoptosis and severe hearing loss.Further investigation indicates that PAK1 deficiency downregulates the phosphorylation of cofilin and ezrin-radixin-moesin and the expression of b II-spectrin,which further decreases the HC synapse density in the basal turn of cochlea and disorganized the HC stereocilia in all three turns of cochlea in Pak1à/àmice.Overall,our work demonstrates that the autism-related gene Pak1 plays a crucial role in hearing function.As the first candidate gene linking autism and hearing loss,Pak1 may serve as a potential target for the clinical diagnosis of autism-related hearing loss. | Cheng Cheng Yilin Hou Zhonghong Zhang Yanfei Wang Ling Lu Liyan Zhang Pei Jiang Song Gao Qiaojun Fang Chengwen Zhu Junyan Gao Xufeng Liu Wei Xie Zhengping Jia Zhigang Xu Xia Gao Renjie Chai | 2021 | Journal of Genetics and Genomics2021，48，4： | 0 |
| 13 | Preparation of porous α-Fe_2O_3-supported Pt and its sensing performance to volatile organic compounds显示文摘Porous α-Fe2O3 was synthesized by a simple hydrothermal treatment of FeCl3 aqueous solution followed by a calcination process. In the synthesis of porous α-Fe2O3, no templates or pore-directing agents were used. The as-prepared porous α-Fe2O3 was further employed as a support for loading Pt nanoparticles. The gas sensing performance of the obtained porous α-Fe2O3-supported Pt to VOCs was investigated. The sensor presented a high response and fast response-recovery characteristic to several VOCs including acetone, ether, methanol, ethanol, butanol and hexanol. Meanwhile, it exhibited a much higher response than the pure α-Fe2O3 at the operating temperature of 260°C. The enhanced sensing properties may be related to the unique porous structure of the α-Fe2O3 support and the promoting effect of active Pt nanoparticles for the sensing reactions. | Yuhong Cheng Yanfei Kang Liwei Wang Yao Wang Shurong Wang Yujin Li Wei Zhong Liangqun Peng | 2012 | Journal of Natural Gas Chemistry2012，21，1： | 0 |
| 14 | Single-cell Sequencing Reveals Clearance of Blastula Chromosomal Mosaicism in In Vitro Fertilization Babies显示文摘Although chromosomal mosaic embryos detected by trophectoderm(TE)biopsy offer healthy embryos available for transfer,high-resolution postnatal karyotyping and chromosome testing of the transferred embryos are insufficient.Here,we applied single-cell multi-omics sequencing for seven infants with blastula chromosomal mosaicism detected by TE biopsy.The chromosome ploidy was examined by single-cell genome analysis,with the cellular identity being identified by single-cell transcriptome analysis.A total of 1616 peripheral leukocytes from seven infants with embryonic chromosomal mosaicism and three control ones with euploid TE biopsy were analyzed.A small number of blood cells showed copy number alterations(CNAs)on seemingly random locations at a frequency of 0%-2.5%per infant.However,none of the cells showed CNAs that were the same as those of the corresponding TE biopsies.The blastula chromosomal mosaicism may be fully self-corrected,probably through the selective loss of the aneuploid cells during development,and the transferred embryos can be born as euploid infants without mosaic CNAs corresponding to the TE biopsies.The results provide a new reference for the evaluations of transferring chromosomal mosaic embryos in certain situations. | Yuan Gao Jinning Zhang Zhenyu Liu Shuyue Qi Xinmeng Guo Hui Wang Yanfei Cheng Shuang Tian Minyue Ma Hongmei Peng Lu Wen Fuchou Tang Yuanqing Yao | 2022 | Genomics, Proteomics & Bioinformatics2022，20，6： | 0 |
