2Impact of meteorological factors on the incidence of childhood hand,foot,and mouth disease(HFMD)analyzed by DLNMs-based time series approach显示文摘Background:Hand,foot,and mouth disease(HFMD)has become an emerging infectious disease in China in the last decade.There has been evidence that meteorological factors can influence the HFMD incidence,and understanding the mechanisms can help prevent and control HFMD.Methods:HFMD incidence data and meteorological data in Minhang District,Shanghai were obtained for the period between 2009 and 2015.Distributed lag non-linear models(DLNMs)were utilized to investigate the impact of meteorological factors on HFMD incidence after adjusting for potential confounders of long time trend,weekdays and holidays.Results:There was a non-linear relationship between temperature and HFMD incidence,the RR of 5th percentile compared to the median is 0.836(95%CI:0.671-1.042)and the RR of 95th percentile is 2.225(95%CI:1.774-2.792),and the effect of temperature varied across age groups.HFMD incidence increased with increasing average relative humidity(%)(RR=1.009,95%CI:1.005-1.015)and wind speed(m/s)(RR=1.197,95%CI:1.118-1.282),and with decreasing daily rainfall(mm)(RR=0.992,95%CI:0.987-0.997)and sunshine hours(h)(RR=0.966,95%CI:0.951-0.980).Conclusions:There were significant relationships between meteorological factors and childhood HFMD incidence in Minhang District,Shanghai.This information can help local health agencies develop strategies for the control and prevention of HFMD under specific climatic conditions.Hongchao Qi Yue Chen Dongli Xu Hualin Su Longwen Zhan Zhiyin Xu Ying Huang Qianshan He Yi Hu Henry Lynn Zhijie Zhang 2018Infectious Diseases of Poverty2018,7,1:17
3Mutation in a novel gene SMALL AND CORDATELEAF 1 affects leaf morphology in cucumber显示文摘Plant species exhibit substantial variation in leaf morphology.VWe isolated a recessive mutant gene termed small and cordate leaf 1(sclh)that causes alteration in both leaf size and shape of cucumber.Compared to wild type leaves,the sclh mutant had fewer numbers of epidermal pavement cells.A single nucleotide polymorphism was associated with this leaf phenotype,which occurred in a putative nucleoside bisphosphate phosphatase.RNA-seq analysis of the wild type and sclh mutant leaves suggested that SCL_1 regulation may not involve known hormonal pathways.Our work identified a candidate gene for SCL_1 that may play a role in leaf development.Dongli Gao Chunzhi Zhang Shu Zhang Bowen Hu Shenhao Wang Zhonghua Zhang Sanwen Huang 2017Journal of Integrative Plant Biology2017,59,10:3

5Discovery of carbon-based strongest and hardest amorphous material显示文摘Carbon is one of the most fascinating elements due to its structurally diverse allo tropic forms stemming from its bonding varieties(sp,sp^(2)and sp^(3)).Exploring new forms of carbon has been the eternal theme of scientific research.Herein,we report on amorphous(AM) carbon materials with a high fraction of sp^(3)bonding recovered from compression of fullerene C_(60) under high pressure and high temperature,previously unexplored.Analysis of photoluminescence and absorption spectra demonstrates that they are semiconducting with a bandgap range of 1.5-2.2 eV,comparable to that of widely used AM silicon.Comprehensive mechanical tests demonstrate that synthesized AM-Ⅲ carbon is the hardest and strongest AM material known to date,and can scratch diamond crystal and approach its strength.The produced AM carbon materials combine outstanding mechanical and electronic properties,and may potentially be used in photovoltaic applications that require ultrahigh strength and wear resistance.Shuangshuang Zhang Zihe Li Kun Luo Julong He Yufei Gao Alexander V.Soldatov Vicente Benavides Kaiyuan Shi Anmin Nie Bin Zhang Wentao Hu Mengdong Ma Yong Liu Bin Wen Guoying Gao Bing Liu Yang Zhang Yu Shu Dongli Yu Xiang-Feng Zhou Zhisheng Zhao Bo Xu Lei Su Guoqiang Yang Olga P.Chernogorova Yongjun Tian 2022National Science Review2022,9,1:2
6Synthesis and oxidation behavior of boron-substituted carbon powders by hot filament chemical vapor deposition显示文摘Boron-substituted carbon powder, BxC1-x with x up to 0.17, has been successfully synthesized by hot filament chemical vapor deposition. The boron concentration in prepared BxC1-x samples can be controlled by varying the relative proportions of methane and diborane. X-ray diffraction, transmission electron microscopy, and electron energy loss spectrum confirm the successful synthesis of an amorphous BC5 compound, which consists of 10―20 nm particles with disk-like morphology. Thermogravimetry measurement shows that BC5 compound starts to oxidize ap-proximately at 620℃ and has a higher oxidation resistance than carbon.HU QianKu WU QingHua SUN Guang LUO XiaoGuang XU Bo YU DongLi HE JuLong 2008Science China(Technological Sciences)2008,51,9:1
7Heat-treated glassy carbon under pressure exhibiting superior hardness,strength and elasticity显示文摘Glassy carbon(GC)is a type of non-graphitizing disordered carbon material at ambient pressure and high temperatures,which has been widely used due to its excellent mechanical properties.Here we report the changes in the microstructure and mechanical properties of GC treated at high pressures(up to 5 GPa)and high temperatures.The formation of intermediate sp2-sp3 phases is identified at moderate treatment temperatures before the complete graphitization of GC,by analyzing synchrotron X-ray diffraction,Raman spectra,and transmission electron microscopy images.The intermediate metastable carbon materials exhibit superior mechanical properties with hardness reaching up to 10 GPa and compressive strength reaching as high as 2.5 GPa,nearly doubling those of raw GC,and improving elasticity and thermal stability.The synthesis pressure used in this study can be achieved in the industry on a commercial scale,enabling the scalable synthesis of this type of strong,hard,and elastic carbon materials.Meng Hu Shuangshuang Zhang Bing Liu Yingju Wu Kun Luo Zihe Li Mengdong Ma Dongli Yu Lingyu Liu Yufei Gao Zhisheng Zhao Yoshio Kono Ligang Bai Guoyin Shen Wentao Hu Yang Zhang Ralf Riedel Bo Xu Julong He Yongjun Tian 2021Journal of Materiomics2021,7,1:1
8Extraordinary high-temperature mechanical properties in binder-free nanopolycrystalline WC ceramic显示文摘From the perspective of high-temperature applications,materials with excellent high-temperature mechanical properties are always desirable.The present work demonstrates that the binder-free nanopolycrystalline WC ceramic with an average grain size of 103 nm obtained by high-pressure and hightemperature sintering exhibits excellent mechanical properties at both room temperature and high temperature up to 1000℃.Specifically,the binder-free nanopolycrystalline WC ceramic still maintains a considerably high Vicker hardness H_(V)of 23.4 GPa at 1000℃,which is only 22%lower than the room temperature H_(V).This outstanding thermo-mechanical stability is superior to that of typical technical ceramics,e.g.SiC,Si_(3)N_(4),Al_(2)O_(3),etc.Nanocrystalline grains with many dislocations,numerous low-energy,highly stableΣ2 grain boundaries,and a relatively low thermal expansion coefficient,are responsible for the observed outstanding high-temperature mechanical properties.Hongfeng Dong Baozhong Li BoBo Liu Yang Zhang Lei Sun Kun Luo Yingju Wu Mengdong Ma Bing Liu Wentao Hu Julong He Dongli Yu Bo Xu Zhisheng Zhao Yongjun Tian 2022Journal of Materials Science & Technology2022,,2:1

11Step distribution of Yb filling fraction during microstructural evolution in skutterudites显示文摘To achieve a better material for thermoelectric power generation device, filled skutterudite Yb0.3 Co_4 Sb_(12) samples were fabricated by melting-quenching-annealing-spark plasma sintering(SPS)method. Two sets of samples, before and after SPS, were investigated. In both the two sets of samples,the average grain size of the samples increases monotonously with the increase of annealing time,while Yb filling fraction firstly increases and then decreases. Yb not filling into the skutterudite remains at the grain boundaries in the form of Yb_2 O_3 after SPS, which could be quantified by the spatially difference method of energy dispersive spectra. Step distribution of Yb filling fraction was observed in the samples annealed for 1 h, which was caused by the microstructural evolution from the peritectic phases to the skutterudite phase. The sample annealed for 3 days and SPS sintered possesses the maximum value of Yb filling fraction 0.249 and the maximum ZT value of 1.24 at 850 K. These results are helpful to better understand the microstructural evolution and Yb filling behavior in skutterudite materials.Jing MEI Zheng YAO Shuya ZHU Dongli HU Ying JIANG Juanjuan XING Hui GU Lidong CHEN 2019Journal of Advanced Ceramics2019,8,1:0
12Competition system for automatically evaluating edge detection algorithms based on the evolutionary game theory显示文摘An ensemble learning algorithm based on game theory is proposed to evaluate algorithms of image analysis and image feature extraction.A competition system is established to implement the algorithm for evaluating the applicability and efficiency of different edge detection algorithms.Through the game in the algorithm competition system,the most suitable algorithm as a winner in the competition can be selected.A group of optimal parameters for the corresponding edge detection can also be found.Firstly,based on the evolutionary game theory,a strategy of the competition of edge extraction algorithms is developed.Secondly,after selecting the most suitable algorithm from the candidates,the overall parameters are optimized.Experiments show that for a specific class of images,several candidate algorithms can be used as a class of preference algorithms based on the final evolutionary result.When analyzing the images,the priority algorithm can be recommended as the best edge detection algorithm from these reference algorithms.It is more effective than traditional methods in determining an algorithm and choosing parameters.Peng Hong Ding Guangtai Zhang Huiran Hu Dongli 2019The Journal of China Universities of Posts and Telecommunications2019,26,5:0
13Preparation of high-performance ultrafine-grained AISI 304L stainless steel under high temperature and pressure显示文摘Bulk ultra-fine grained(UFG) AISI 304 L stainless steel with excellent mechanical properties was prepared by a high-temperature and high-pressure(HTHP) method using nanocrystalline AISI 304 L stainless steel powders obtained from ball milling. Samples were sintered in high-pressure conditions using the highest martensite content of AISI 304 L stainless steel powders milled for 25 h. Analyses of phase composition and grain size were accomplished by X-ray diffraction and Rietveld refinement. By comparing the reverse martensite transformation under vacuum and HTHP treat, we consider that pressure can effectively promote the change in the process of transformation. Compared with the solid-solution-treated 304 L,the hardness and yield strength of the samples sintered under HTHP are considerably higher. This method of preparation of UFG bulk stainless steel may be widely popularised and used to obtain UFG metallic materials with good comprehensive performance.Peng Wang Jinzan Zhang Yang Zhang Haitao Wang Wentao Hu Dongli Yu 2016Progress in Natural Science:Materials International2016,26,4:0
