| 5 | Discrete Variable Structural Optimization based on Multidirectional Fuzzy Genetic Algorithm显示文摘Round method is the common method for discrete variable optimization in optimal design of complex mechanical structures;however,it has some disadvantages such as poor precision,simple model and lacking of working conditions' description,etc.To solve these problems,a new model is constructed by defining parameterized fuzzy entropy,and the rationality of parameterized fuzzy entropy is verified.And a new multidirectional searching algorithm is further put forward,which takes information of actual working conditions into consideration and has a powerful local searching capability.Then this new algorithm is combined with the GA by the fuzzy clustering algorithm(FCA).With the application of FCA,the optimal solution can be effectively filtered so as to retain the diversity and the elite of the optimal solution,and avoid the structural re-analysis phenomenon between the two algorithms.The structure design of a high pressure bypass-valve body is used as an example to make a structural optimization by the proposed HGA and finite element method(FEM),respectively.The comparison result shows that the improved HGA fully considers the characteristic of discrete variable and information of working conditions,and is more suitable to the optimal problems with complex working conditions.Meanwhile,the research provides a new approach for discrete variable structure optimization problems. | LAI Yinan DAI Ye BAI Xue CHEN Dongyan | 2012 | Chinese Journal of Mechanical Engineering2012，25，2： | 12 |

| 8 | Design and key parameter optimization of an agitated soybean seed metering device with horizontal seed filling显示文摘Since the low seed filling speed of mechanical seed metering devices reduces the low qualified rate of seed spacing during high-speed practices,it is significant to design agitated seed metering devices with horizontal seed filling that are suitable for high-speed practices.The combination of horizontal seed filling and agitated seed filling can accelerate the seed filling of mechanical seed metering devices,and improve the qualified rate of seed spacing during high-speed practices.In this study,theoretical analysis,discrete element method-based simulation and indoor bench test verification were conducted to investigate how key parameters of the agitated seed metering device with horizontal seed filling(angles,installation position and number of agitating plates,diameters of convex spoons)would affect the characteristics of soybean seed movement,seed number and seeding performance(qualified index,multiple index,missing seeding index)under different working speeds.Computer-based simulation,test design and regression analysis were combined to analyze the population moving rules and optimize the design parameters of seed metering devices.Based on the test scheme as designed,simulations were conducted on Fluent EDEM,and the optimal angle of the agitating plates was determined by analyzing the population migrating rules.Regression equations were established through the regression of test results,and used to find out the optimal design parameters(diameter of convex spoon,positions and number of agitating plates)of seed metering devices.Then the optimal parameter combination among different working conditions was determined that the angle,position and number of agitating plates were 30°,24.4 mm,and 13,respectively,and the diameter of convex spoon was 11.0 mm.With the optimal parameter combination and at the seeding speed of 12 km/h,the qualified index,multiple index and missing seeding index were 93.1%,2.1%and 4.8%,respectively.Under high-speed practices,the new seed metering device was not significantly different from the pneumatic seed metering device,but significantly outperformed the mechanical seed metering device. | Honglei Jia Yulong Chen Jiale Zhao Mingzhuo Guo Dongyan Huang Jian Zhuang | 2018 | International Journal of Agricultural and Biological Engineering2018，11，2： | 8 |
| 9 | Large-scale synthesis of hierarchical MnO_2 for benzene catalytic oxidation显示文摘Hierarchical sea-urchin-shaped manganese oxide microspheres were synthesized via a tacile metnoa based on the reaction between KMnO_4 and MnSO_4 in HNO_3 solution at 50 C.The average diameter of the microspheres is ~850 nm.The microspheres consist of a core of diameter of ~800 nm and nanorods of width ~50 nm.The nanorods exist at the edge of the core.The Brunauer-Emmett-Teller surface area of the sea-urchin-shaped microspheres is 259.4 m^2/g.A possible formation mechanism of the hierarchical sea-urchin-shaped microspheres is proposed.The temperature for 90%conversion of benzene(T_(90)%) on the hierarchical urchin-shaped MnO_2 microspheres is about 218℃. | Dongyan Li Genli Shen Wenxiang Tang Haidi Liu Yunfa Chen | 2014 | Particuology2014，12，3： | 4 |
| 10 | Characterization of SoxB2 and SoxC genes in Amphi-oxus (Branchiostoma belcheri):Implications for their evolutionary conservation显示文摘Most Sox genes directly affect cell fate determination and differentiation. In this study,we isolated two Sox genes:SoxB2 and SoxC from amphioxus (Branchiostoma belcheri),the closest living invertebrate relative of the vertebrates. Alignments of SoxB2 and SoxC protein sequences and their vertebrate homologs show high conservation of their HMG domains. Phylogenic analysis shows that amphioxus SoxB2 and SoxC fall out of the vertebrate branches,suggesting that vertebrate homologs might arise from gene duplications during evolution. The two genes possess similar spatial and temporal expression patterns during embryogenesis and in adults. They are both maternally inherited. During neurulation,they are expressed in the neural ectoderm and archenterons. In adults,they are expressed not only in the nerve cord,but also in the gut,midgut diverticulum,gill and oocytes. These results suggest that amphioxus SoxB2 and SoxC might co-function and have conserved functions in the nervous system and gonads as their vertebrate homologs. | LIN YuShuang,CHEN DongYan,FAN QiuSheng & ZHANG HongWei Institute of Developmental Biology,Life Science College,Key Lab of Experimental Teratology of Ministry of Education,Shandong University,Jinan 250100,China | 2009 | Science China(Life Sciences)2009，52，9： | 4 |
| 11 | Design and synthesis of porous non-noble metal oxides for catalytic removal of VOCs显示文摘The design and synthesis of highly active non-noble metal oxide catalysts, such as transition- and rare-earth-metal oxides, have attracted significant attention because of their high efficiency and low cost and the resultant potential applications for the degradation of volatile organic compounds(VOCs). The structure-activity relationships have been well-studied and used to facilitate design of the structure and composition of highly active catalysts. Recently, non-noble metal oxides with porous structures have been used as catalysts for deep oxidation of VOCs, such as aromatic hydrocarbons, aliphatic compounds, aldehydes, and alcohols, with comparable activities to their noble metal counterparts. This review summarizes the growing literature regarding the use of porous metal oxides for the catalytic removal of VOCs, with emphasis on design of the composition and structure and typical synthetic technologies. | Wenxiang Tang Gang Liu Dongyan Li Haidi Liu Xiaofeng Wu Ning Han Yunfa Chen | 2015 | Science China Chemistry2015，58，9： | 4 |
| 12 | Catalytic performance of hybrid Pt@ZnO NRs on carbon fibers for methanol electro-oxidation显示文摘A novel Pt@ZnO nanorod/carbon fiber(NR/CF) with hierarchical structure was prepared by atomic layer deposition combined with hydrothermal synthesis and magnetron sputtering(MS). The morphology of Pt changes from nanoparticle to nanorod bundle with controlled thickness of Pt between 10 and 50 nm.Significantly, with the increase of voltage from 0 to 0.6 V(vs. standard calomel electrode), the prompt photocurrent generated on Zn O NR/CF increases from 0.235 to 0.725 m A. Besides, the Pt@Zn O NR/CF exhibited higher electrochemical active surface area(ECSA) value, better methanol oxidation ability and CO tolerance than Pt@CF, which demonstrated the importance of the multifunctional Zn O support. As the thickness of Pt increasing from 10 to 50 nm, the ECSA values were improved proportionally, leading to the improvement of methanol oxidation ability. More importantly, UV radiation increased the density of peak current of Pt@Zn O NR/CF towards methanol oxidation by additional 42.4%, which may be due to the synergy catalysis of UV light and electricity. | Dongyan Li Chen Gu Feng Han Zhaoxiang Zhong Weihong Xing | 2017 | Chinese Journal of Chemical Engineering2017，25，12： | 3 |
| 13 | Identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge, Guyana显示文摘Here,we report the identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge,Guyana.In March 2019,14 employees of Chongqing Bosai Mining Company,China,working in a manganese mining of Guyana,had unexplained fever,and two of them died.We obtained lung and brain tissues as well as the blood samples from the two deceased cases(patient No.1 and 2),and bronchoscopy lavages and cerebrospinal fluid samples from one severe case(patient No.3),respectively.All samples were tested by pathological examination,high-throughput sequencing,and real-time PCR.Pathological detection showed the presence of spore-like structures in the lung tissue of patient No.1,indicating a fungal infection in this patient.Nanopore sequencing identified the existing of H.capsulatum in the lung tissue sample within 13 h.Next-generation sequencing identified specific fragments of H.capsulatum in all of the samples tested(lung,brain and blood serum from the deceased cases,and plasma from the severe case).Real-time PCR assays did not reveal any viral infection related to transmission from bat feces.We conclude that H.capsulatum was the causative pathogen of this disease cluster based on epidemiologic,clinical,pathological and nucleic acid evidence. | Ji Wang Weimin Zhou Hua Ling Xiaoping Dong Yi Zhang Jiandong Li Yong Zhang Jingdong Song William J.Liu Yang Li Ruiqing Zhang Wei Zhen Kun Cai Shuangli Zhu Dongyan Wang Jinbo Xiao Yigang Tong Wenli Liu Lihua Song Wei Wu Yang Liu Xiang Zhao Ruihuan Wang Sheng Ye Jing Wang Roujian Lu Baoying Huang Fei Ye Wenwen Lei Rongbao Gao Qi Shi Cao Chen Jun Han Wenbo Xu George F.Gao Xuejun Ma Guizhen Wu | 2019 | Biosafety and Health2019，1，3： | 3 |
| 14 | Effects of brewers' spent grain protein hydrolysates on gas production, ruminal fermentation characteristics, microbial protein synthesis and microbial community in an artificial rumen fed a high grain diet显示文摘Background: Brewers' spent grain(BSG) typically contains 20% – 29% crude protein(CP) with high concentrations of glutamine, proline and hydrophobic and non-polar amino acid, making it an ideal material for producing valueadded products like bioactive peptides which have antioxidant properties. For this study, protein was extracted from BSG, hydrolyzed with 1% alcalase and flavourzyme, with the generated protein hydrolysates(AlcH and FlaH)showing antioxidant activities. This study evaluated the effects of AlcH and FlaH on gas production, ruminal fermentation characteristics, nutrient disappearance, microbial protein synthesis and microbial community using an artificial rumen system(RUSITEC) fed a high-grain diet.Results: As compared to the control of grain only, supplementation of FlaH decreased(P < 0.01) disappearances of dry matter(DM), organic matter(OM), CP and starch, without affecting fibre disappearances;while AlcH had no effect on nutrient disappearance. Neither AlcH nor FlaH affected gas production or VFA profiles, however they increased(P < 0.01) NH_3-N and decreased(P < 0.01) H_2 production. Supplementation of FlaH decreased(P < 0.01)the percentage of CH_4 in total gas and dissolved-CH_4(dCH_4) in dissolved gas. Addition of monensin reduced(P < 0.01) disappearance of nutrients, improved fermentation efficiency and reduced CH_4 and H_2 emissions.Total microbial nitrogen production was decreased(P < 0.05) but the proportion of feed particle associated(FPA) bacteria was increased with FlaH and monensin supplementation. Numbers of OTUs and Shannon diversity indices of FPA microbial community were unaffected by AlcH and FlaH;whereas both indices were reduced(P < 0.05) by monensin. Taxonomic analysis revealed no effect of AlcH and FlaH on the relative abundance(RA) of bacteria at phylum level, whereas monensin reduced(P < 0.05) the RA of Firmicutes and Bacteroidetes and enhanced Proteobacteria. Supplementation of FlaH enhanced(P < 0.05) the RA of genus Prevotella, reduced Selenomonas, Shuttleworthia, Bifidobacterium and Dialister as compared to control;monensin reduced(P < 0.05) RA of genus Prevotella but enhaced Succinivibrio.Conclusions: The supplementation of FlaH in high-grain diets may potentially protect CP and starch from ruminal degradation, without adversely affecting fibre degradation and VFA profiles. It also showed promising effects on reducing CH_4 production by suppressing H_2 production. Protein enzymatic hydrolysates from BSG using flavourzyme showed potential application to high value-added bio-products. | Tao Ran Long Jin Ranithri Abeynayake Atef Mohamed Saleem Xiumin Zhang Dongyan Niu Lingyun Chen Wenzhu Yang | 2021 | Journal of Animal Science and Biotechnology2021，12，1： | 3 |
| 15 | Investigation and experimental validation of curcumin-related mechanisms against hepatocellular carcinoma based on network pharmacology显示文摘Objective:To determine the potential molecular mechanisms underlying the therapeutic effect of curcumin on hepatocellular carcinoma(HCC)by network pharmacology and experimental in vitro validation.Methods:The predictive targets of curcumin or HCC were collected from several databases.the identified overlapping targets were crossed with Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analyses using the Database for Annotation,Visualization,and Integrated Discovery(DAVID)platform.Two of the candidate pathways were selected to conduct an experimental verification.The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide tetrazolium(MTT)assay was used to determine the effect of curcumin on the viability of Hep G2 and LO2 cells.The apoptosis and autophagy of Hep G2 cells were respectively detected by flow cytometry and transmission electron microscopy.Besides,western blot and real-time polymerase chain reaction(PCR)were employed to verify the p53 apoptotic pathway and adenosine 5’-monophosphate(AMP)-activated protein kinase(AMPK)autophagy pathway.Hep G2 cells were pretreated with pifithrin-α(PFT-α)and GSK690693 for further investigation.Results:The 167 pathways analyzed by KEGG included apoptosis,autophagy,p53,and AMPK pathways.The GO enrichment analysis demonstrated that curcumin was involved in cellular response to drug,regulation of apoptotic pathway,and so on.The in vitro experiments also confirmed that curcumin can inhibit the growth of Hep G2 cells by promoting the apoptosis of p53 pathway and autophagy through the AMPK pathway.Furthermore,the protein and messenger RNA(m RNA)of the two pathways were downregulated in the inhibitor-pretreated group compared with the experimental group.The damage-regulated autophagy modulator(DRAM)in the PFT-α-pretreated group was downregulated,and p62 in the GSK690693-pretreated group was upregulated.Conclusions:Curcumin can treat HCC through the p53 apoptotic pathway and the AMPK/Unc-51-like kinase 1(ULK1)autophagy pathway,in which the mutual transformation of autophagy and apoptosis may occur through DRAM and p62. | Yang CHEN Qian LI Sisi REN Ting CHEN Bingtao ZHAI Jiangxue CHENG Xiaoyan SHI Liang SONG Yu FAN Dongyan GUO | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，8： | 3 |
| 16 | Characterization of the immune defense related tissues,cells,and genes in amphioxus显示文摘Amphioxus is an important animal model for phylogenetic analysis,including comparative immunology.Exploring the immune system in amphioxus contributes to our understanding of the origin and evolution of the vertebrate immune system.We investigated the amphioxus immune system using ultrastructural examination and in situ hybridization.The expression patterns of TLR1(toll-like receptor 1),C1Q(complement component 1,q subcomponent),ECSIT(evolutionarily conserved signaling intermediate in Toll pathways),SoxC,DDAHa(Dimethylarginine dimethylaminohydrolase a),and NOS(nitric oxide synthase) show that these genes play key roles in amphioxus immunity.Our results suggest that the epidermis and alimentary canal epithelium may play important roles in immune defense,while macrophages located in the coelom and so-called lymph spaces may also be crucial immune cells. | LIN YuShuang CHEN DongYan ZHANG Wei CAI ZhaoPing CHEN ZhongKe ZHANG Ning MAO BingYu ZHANG HongWei | 2011 | Science China(Life Sciences)2011，54，11： | 2 |
| 17 | Dielectr ic barr ier discharge plasma-assisted modification of g-C_(3)N_(4)/Ag_(2)O/TiO_(2)-NRs composite enhanced photoelectrocatalytic activity显示文摘Dielectric barrier discharge(DBD)plasma applied as surface treatment technology was employed for the modification of Ag_(2)O and graphitic carbon nitride(g-C_(3)N_(4))powders.Subsequently,the pretreated powders were sequentially loaded onto TiO_(2)nanorods(TiO_(2)-NRs)via electro-deposition,followed by calcination at N_(2)atmosphere.The results indicated that at the optimal plasma discharge time of 5 min for modification of g-C_(3)N_(4)and Ag_(2)O,photocurrent density of ternary composite was 6 times to bare TiO_(2)-NRs under UV-visible light irradiation.Phenol was degraded by using DBD plasma-modified g-C_(3)N_(4)/Ag_(2)O/TiO_(2)-NRs electrode to analyze the photoelectrocatalytic performance.The removal rate of phenol for g-C_(3)N_(4)-5/Ag_(2)O-5/TiO_(2)-NRs electrode was about 3.07 times to that for TiO_(2)-NRs electrode.During active species scavengers'analysis,superoxide radicals and hydroxyl radicals were the main oxidation active species for pollutants degradation.A possible electron-hole separation and transfer mechanism of ternary composite with high photoelectrocatalytic performance was proposed. | Yupei Long Chenchen Yuan Xiaomin Wang Dongyan Jin Hong Zhou Qiongyin Wang Chenyang Lu Yuqi Chen Yanqing Cong Qi Wang Yi Zhang | 2021 | Journal of Environmental Sciences2021，33，6： | 2 |
| 18 | Kinetics of Evaporation of Zn and Pb from Carbon-bearing Pellets Made of Dust Containing Zn-Pb-Fe Oxides显示文摘The influence of reduction temperature, size of coal powder and the carbon content on the evaporation rates of Zn and Pb in pellets made of ZnO-PbO-FeO bearing dust has been investigated between 1100-1300℃. The evaporation rate of Zn and Pb obtained from the experiments has been analyzed with kinetic models. The results show that the control step for evaporation of Zn is reduction reaction of ZnO by CO at the interface,and that the evaporation rate of Pb is controlled by the volatilization of reduction products, i.e. liquid lead. The overall apparent activation energies of Zn and Pb evaporation from the pellet are 79.42kJ/mol and 88.74kJ/mol respectively. | Weiqing Chen, Dongyan Wang, Rongzhang Zhou, Zongcai Lin (Metallurgy School, University of Science and Technology Beijing, Beijing 100083, China) | 2000 | International Journal of Minerals,Metallurgy and Materials2000，14，3： | 2 |
