| 1 | An elastic-plastic contact model for line contact structures显示文摘Although numerical simulation tools are now very powerful,the development of analytical models is very important for the prediction of the mechanical behaviour of line contact structures for deeply understanding contact problems and engineering applications.For the line contact structures widely used in the engineering field,few analytical models are available for predicting the mechanical behaviour when the structures deform plastically,as the classic Hertz’s theory would be invalid.Thus,the present study proposed an elastic-plastic model for line contact structures based on the understanding of the yield mechanism.A mathematical expression describing the global relationship between load history and contact width evolution of line contact structures was obtained.The proposed model was verified through an actual line contact test and a corresponding numerical simulation.The results confirmed that this model can be used to accurately predict the elastic-plastic mechanical behaviour of a line contact structure. | Haibin Zhu Yingtao Zhao Zhifeng He Ruinan Zhang Shaopeng Ma | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，5： | 8 |
| 2 | Copper as a single metal atom based photo-,electro-,and photoelectrochemical catalyst decorated on carbon nitride surface for efficient CO_(2) reduction:A review显示文摘The processes of photocatalytic CO_(2) reduction(pCO_(2)R)and electrochemical CO_(2) reduction(ECO_(2)R)have attracted considerable interest owing to their high potential to address many environmental and energy-related issues.In this aspect,a single Cu atom decorated on a carbon nitride(CN)surface(Cu-CN)has gained increasing popularity because of its unique advantages,such as excellent atom utilization and ultrahigh catalytic activity.CN-particularly graphitic CN(g-C_(3)N_(4))-is a photo-and electrocatalyst and used as an important support material for single Cu atom-based catalysts.These key functions of Cu-CN-based catalysts can improve the catalytic performance and stability in the pCO_(2)R and ECO_(2)R during the application process.In this review,we focus on Cu as a single metal atom decorated on CN for efficient photoelectrochemical CO_(2) reduction(pECO_(2)R),where ECO_(2)R increases the electrocatalytic active area and promotes electron transfer,while pCO_(2)R enhances the surface redox reaction by efficiently using photogenerated charges and offering integral activity as well as an active interface between Cu and CN.Interactions of single Cu atom-based photo-,electro-,and photoelectrochemical catalysts with g-C_(3)N_(4) are discussed.Moreover,for a deeper understanding of the history of the development of pCO_(2)R and ECO_(2)R,the basics of CO_(2) reduction,including pCO_(2)R and ECO_(2)R over g-C_(3)N_(4),as well as the structural composition,characterization,unique design,and mechanism of a single atom site are reviewed in detail.Finally,some future prospects and key challenges are discussed. | Lulu Li Israr Masood ul Hasan Farwa Ruinan He Luwei Peng Nengneng Xu Nabeel Khan Niazi Jia-Nan Zhang Jinli Qiao | 2022 | Nano Research Energy2022，1，2： | 7 |
| 3 | Simultaneous Prediction of Wheat Yield and Grain Protein Content Using Multitask Deep Learning from Time-Series Proximal Sensing显示文摘Wheat yield and grain protein content(GPC)are two main optimization targets for breeding and cultivation.Remote sensing provides nondestructive and early predictions of yield and GPC,respectively.However,whether it is possible to simultaneously predict yield and GPC in one model and the accuracy and influencing factors are still unclear.In this study,we made a systematic comparison of different deep learning models in terms of data fusion,time-series feature extraction,and multitask learning.The results showed that time-series data fusion significantly improved yield and GPC prediction accuracy with R 2 values of 0.817 and 0.809. | Zhuangzhuang Sun Qing Li Shichao Jin Yunlin Song Shan Xu Xiao Wang Jian Cai Qin Zhou Yan Ge Ruinan Zhang Jingrong Zang Dong Jiang | 2022 | Plant Phenomics2022，4，1： | 4 |
| 4 | Milk-derived exosomes exhibit versatile effects for improved oral drug delivery显示文摘As endogenous courier vesicles,exosomes play crucial roles in macromolecule transmission and intercellular communication.Therefore,exosomes have drawn increasing attention as biomimetic drug-delivery vehicles over the past few years.However,few studies have investigated the encapsulation of peptide/protein drugs into exosomes for oral administration.Additionally,the mechanisms underlying their biomimetic properties as oral delivery vehicles remain unknown.Herein,insulin-loaded milk-derived exosomes(EXO@INS)were fabricated and the in vivo hypoglycemic effect was investigated on type I diabetic rats.Surprisingly,EXO@INS(50 and 30 IU/kg)elicited a more superior and more sustained hypoglycemic effect compared with that obtained with subcutaneously injected insulin.Further mechanism studies indicated that the origin of excellent oral-performance of milk-derived exosomes combined active multi-targeting uptake,pH adaptation during gastrointestinal transit,nutrient assimilation related ERK1/2 and p38 MAPK signal pathway activation and intestinal mucus penetration.This study provides the first demonstration that multifunctional milk-derived exosomes offer solutions to many of the challenges arising from oral drug delivery and thus provide new insights into developing naturally-equipped nanovehicles for oral drug administration. | Lei Wu Lingling Wang Xi Liu Yuli Bai Ruinan Wu Xiang Li Yutong Mao Ling Zhang Yongxiang Zheng Tao Gong Zhirong Zhang Yuan Huang | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 1 |
| 5 | Standardized ileal digestibility of amino acids in soybean meal fed to non-pregnant and pregnant sows显示文摘Background Two studies were designed to determine standard ileal crude protein(CP)and amino acid(AA)digestibility of soybean meal(SBM)from different origins fed to non-pregnant and pregnant sows.Seven solvent-extracted SBMs from soybeans produced in the USA,Brazil,and China were selected.In Exp.1,eight different diets were created:a nitrogen(N)-free diet and 7 experimental diets containing SBM from different origins as the only N source.Eight non-pregnant,multiparous sows were arranged in an 8×8 Latin square design(8 periods and 8 diets).In Exp.2,the diet formula was the same as in Exp.1.Eight gestating sows(parity 3)were assigned to 4 different diets in a replicated 4×3 Youden square design(three periods and four diets)in mid-gestation and again in late-gestation stages.Results When fed to non-pregnant and late-gestating sows,the standardized ileal digestibility(SID)of CP and most AAs from different SBM were not significantly different(P>0.05).When fed to mid-gestating sows,the SID values for Arg,His,Lys,Phe,Cys,Gly,Ser,and Tyr in SBM 1 were lower than in SBM 4 and 5(P<0.05),whereas SID for Leu from SBM 5 was higher than in SBM 1 and 4(P<0.05).SID values for Ile,Ala,and Asp from SBM 4 were lower than in SBM 1 and 5(P<0.05).Sows had significantly greater SID values for Lys,Ala,and Asp during mid-gestation when compared with late-gestation stages(P<0.05).Mid-gestating sows had greater SID value for Val and lower SID value for Tyr when compared with non-pregnant and late-gestating sows(P<0.01),whereas non-pregnant sows had significantly greater SID value for Met when compared with gestating sows(P<0.01).Conclusions When fed to mid-gestating sows,the SID values for most AAs varied among SBM samples.The SID values for Lys,Met,Val,Ala,Asp,and Tyr in SBM were affected by sow gestation stages.Our findings provide a cornerstone for accurate SBM use in sow diets. | Ke Wang Ya Wang Lei Guo Yong Zhuo Lun Hua Lianqiang Che Shengyu Xu Ruinan Zhang Jian Li Bin Feng Zhengfeng Fang Xuemei Jiang Yan Lin De Wu | 2024 | Journal of Animal Science and Biotechnology2024，15，1： | 0 |
| 6 | The genomic and epigenetic footprint of local adaptation to variable climates in kiwifruit显示文摘A full understanding of adaptive genetic variation at the genomic level will help address questions of how organisms adapt to diverse climates.Actinidia eriantha is a shade-tolerant species,widely distributed in the southern tropical region of China,occurring in spatially heterogeneous environments.In the present study we combined population genomic,epigenomic,and environmental association analyses to infer population genetic structure and positive selection across a climatic gradient,and to assess genomic offset to climatic change for A.eriantha.The population structure is strongly shaped by geography and influenced by restricted gene f low resulting from isolation by distance due to habitat fragmentation.In total,we identified 102 outlier loci and annotated 455 candidate genes associated with the genomic basis of climate adaptation,which were enriched in functional categories related to development processes and stress response;both temperature and precipitation are important factors driving adaptive variation.In addition to single-nucleotide polymorphisms(SNPs),a total of 27 single-methylation variants(SMVs)had significant correlation with at least one of four climatic variables and 16 SMVswere located in or adjacent to genes,several of whichwere predicted to be involved in plant response to abiotic or biotic stress.Gradient forest analysis indicated that the central/east populations were predicted to be at higher risk of future population maladaptation under climate change.Our results demonstrate that local climate factors impose strong selection pressures and lead to local adaptation.Such information adds to our understanding of adaptive mechanisms to variable climates revealed by both population genome and epigenome analysis. | Xu Zhang Rui Guo Ruinan Shen Jacob BLandis Quan Jiang Fang Liu Hengchang Wang Xiaohong Yao | 2023 | Horticulture Research2023，10，4： | 0 |
| 7 | Evaluation and comparison of antibacterial activities of edible vegetable oils in China显示文摘To evaluate antibacterial activities of edible vegetable oils in China for healthy consumption, we investigated the antibacterial activities of extracts from 6 edible vegetable oils and rapeseed oils at different refining levels on 4 bactria (Staphylococcus aureus,Bacillus subtilis, Escherichia coli and Pseudomonas strains) by disc diffusion test. Results showed that camellia oil had considerable antibacterial activity against E. coli with antibacterial rate of 108.3%. Perilla oil, sunflower seed oil, and flaxseed oil showed the highest antibacterial activities against B. subtilis with the antibacterial rates of 108.3%, 102.8%and94.4%respectively. Moreover, the extracts of rapeseed oils obtained by different processing technologies showed significantly different antibacterial effects. Two crude oils and grade4 rapeseed oil showed antibacterial rates of more than 40%, whereas grade 1 and 2 rapeseed oils showed antibacterial rates of less than 20%. Therefore, it was recommended to use rapeseed oil rather than refined rapeseed oil because of higher antibacterial activities. It was suggested that proper refining processes should be taken to obtain the edible oils with higher antibacterial activities. | Ruinan Yang Sujun Wang Liangxiao Zhang Xiupin Wang Fei Ma Jin Mao Qi Zhang Peiwu Li | 2018 | Oil Crop Science2018，3，1： | 0 |
| 8 | Differential responses of weaned piglets to supplemental porcine or chicken plasma in diets without inclusion of antibiotics and zinc oxide显示文摘This study was conducted to investigate the effects of spray-dried porcine plasma protein(SDPP)or spray-dried chicken plasma protein(SDCP)supplementation in diets without the inclusion of antibiotics and zinc oxide(ZnO)on growth performance,fecal score,and fecal microbiota in early-weaned piglets.A total of 192 healthy weaning piglets(Duroc×Landrace×Yorkshire,21 d old)were blocked by BW(6.53±0.60 kg)and randomly assigned to 4 dietary treatments:negative control(NC,basal diet),positive control(PC),basal diet+ZnO at 2 g/kg and antibiotics at 0.8 g/kg,SDPP(containing 5%SDPP),and SDCP(containing 5%SDCP).The experiment lasted 14 d.The SDPP group had higher(P<0.05)final BW,average daily gain and average daily feed intake than the NC and SDCP groups.The percentage of piglets with fecal scores at 2 or≥2 was higher(P<0.05)in the NC and SDCP groups than in the PC group.A decreased(P<0.05)bacterial alpha diversity and Bacteroidetes abundance,but increased(P<0.05)Firmicutes abundance were observed in the PC and SDPP groups when compared to the NC group.The relative abundance of Lactobacillus was higher(P<0.05)in the SDPP than in the SDCP group,and that of Streptococcus was higher(P<0.01)in the PC and SDPP groups than in the NC group.The PC group also had higher(P<0.01)Faecalibacterium abundance than the NC and SDCP groups.Additionally,the SDCP group had higher(P<0.05)serum urea nitrogen than those fed other diets,and lower(P<0.10)shortchain fatty acids to branched-chain fatty acids ratio than the PC and SDPP groups.Overall,SDPP was a promising animal protein for piglets in increasing feed intake,modifying gut microbiota profile,reducing gut protein fermentation and alleviating diarrhea frequency,thus promoting growth performance,under the conditions with limited in-feed utilization of antibiotics and ZnO. | Li Zhe Lunxiang Yang Sen Lin Fangyuan Chen Peng Wang Lourens Heres Yong Zhuo Jiayong Tang Yan Lin Shengyu Xu Xiaoling Zhang Xuemei Jiang Lingjie Huang Ruinan Zhang Lianqiang Che Gang Tian Bin Feng De Wu Zhengfeng Fang | 2021 | Animal Nutrition2021，，4： | 0 |

| 10 | Implications of vitamin D for flesh quality of grass carp(Ctenopharyngodon idella):antioxidant ability,nutritional value,sensory quality,and myofiber characteristics显示文摘Background Muscle represents a unique and complex system with many components and comprises the major edible part of animals.Vitamin D is a critical nutrient for animals and is known to enhance calcium absorption and immune response.In recent years,dietary vitamin D supplementation in livestock has received increased attention due to biological responses including improving shear force in mammalian meat.However,the vitamin D acquisition and myofiber development processes in fish differ from those in mammals,and the effect of vitamin D on fish flesh quality is poorly understood.Here,the influence of dietary vitamin D on fillet quality,antioxidant ability,and myofiber development was examined in grass carp(Ctenopharyngodon idella).Methods A total of 540 healthy grass carp,with an initial average body weight of 257.24±0.63 g,were allotted in 6 experimental groups with 3 replicates each,and respectively fed corresponding diets with 15.2,364.3,782.5,1,167.9,1,573.8,and 1,980.1 IU/kg vitamin D for 70 d.Results Supplementation with 1,167.9 IU/kg vitamin D significantly improved nutritional value and sensory quality of fillets,enhancing crude protein,free amino acid,lipid,and collagen contents;maintaining an ideal pH;and reduc-ing lactate content,shear force,and cooking loss relative to respective values in the control(15.2 IU/kg)group.Average myofiber diameter and the frequency of myofibers>50μm in diameter increased under supplementation with 782.5–1,167.9 IU/kg vitamin D.Levels of oxidative damage biomarkers decreased,and the expression of antioxi-dant enzymes and nuclear factor erythroid 2-related factor 2 signaling molecules was upregulated in the 1,167.9 IU/kg vitamin D treatment compared to respective values in the control group.Furthermore,vitamin D supplementation activated cell differentiation by enhancing the expression of myogenic regulatory factors and myocyte enhancer factors compared to that in the control group.In addition,supplementation with 1,167.9 IU/kg vitamin D improved protein deposition associated with protein synthesis molecule(target of rapamycin)signaling and vitamin D receptor paralogs,along with inhibition of protein degradation(forkhead box protein 1)signaling.Conclusions Overall,the results demonstrated that vitamin D strengthened antioxidant ability and myofiber devel-opment,thereby enhancing nutritional value and sensory quality of fish flesh.These findings suggest that dietary vitamin D supplementation is conducive to the production of nutrient-rich,high quality aquaculture products. | Yao Zhang Chaonan Li Xiaoqiu Zhou Weidan Jiang Pei Wu Yang Liu Hongmei Ren Lu Zhang Haifeng Mi Jiayong Tang Ruinan Zhang Lin Feng | 2023 | Journal of Animal Science and Biotechnology2023，14，6： | 0 |
| 11 | Comparative effects of enzymatic soybean,fish meal and milk powder in diets on growth performance,immunological parameters,SCFAs production and gut microbiome of weaned piglets显示文摘Background:The objective of this study was to evaluate the replacement effects of milk powder(MK)and fish meal(FM)by enzymatic soybean(ESB)in diets on growth performance,immunological parameters,SCFAs production and gut microbiome of weaned piglets.Methods:A total of 128 piglets with initial body weight at 6.95±0.46 kg,were randomly assigned into 4 dietary treatments with 8 replicates per treatment and 4 piglets per replicate for a period of 14 d.Piglets were offered isonitrogenous and iso-energetic diets as follows:CON diet with MK and FM as high quality protein sources,ESB plus FM diet with ESB replacing MK,ESB plus MK diet with ESB replacing FM,and ESB diet with ESB replacing both MK and FM.Results:No significant differences were observed in growth performance among all treatments(P>0.05).However,piglets fed ESB plus FM or ESB diet had increased diarrhea index(P<0.01),and lower digestibility of dry matter(DM),gross energy(GE)or crude protein(CP),relative to piglets fed CON diet(P<0.01).Moreover,the inclusion of ESB in diet markedly decreased the plasma concentration of HPT and fecal concentration of butyric acid(BA)(P<0.01).The High-throughput sequencing of 16S rRNA gene V3−V4 region of gut microbiome revealed that the inclusion of ESB in diet increased the alpha diversity,and the linear discriminant analysis effect size(LEfSe)showed that piglets fed with ESB plus FM or ESB diet contained more gut pathogenic bacteria,such as g_Peptococcus,g_Veillonella and g_Helicobacter.Conclusion:The inclusion of ESB in diet did not markedly affect growth performance of piglets,but the replacement of MK or both MK and FM by ESB increased diarrhea index,which could be associated with lower nutrients digestibility and more gut pathogenic bacteria.However,piglets fed diet using ESB to replace FM did not markedly affect gut health-related parameters,indicating the potential for replacing FM with ESB in weaning diet. | Yingjie Li Yang Liu Jiangnan Wu Qiuhong Chen Qiang Zhou Fali Wu Ruinan Zhang Zhengfeng Fang Yan Lin Shengyu Xu Bin Feng Yong Zhuo De Wu Lianqiang Che | 2022 | Journal of Animal Science and Biotechnology2022，13，2： | 0 |
| 12 | Comparison of anthocyanin and fatty acid in black and ordinary peanuts显示文摘In this study, anthocyanin and fatty acid compositions between black and ordinary peanuts were compared. Results showed that black peanuts contained 93.90±18.36 μg/g of cyanidin, which was significantly higher than that of ordinary peanuts. In addition, although both of black and ordinary peanuts shared some specific fatty acids, 4 fatty acids in black peanuts were significantly different from those in ordinary peanuts, which could be used as markers to distinguish black peanut from ordinary ones. This study might serve as a reference for authenticity identification and further nutritional researches on black peanut. | Qian Xu Xiaorong Huang Xiao Wang Ruinan Yang Liangxiao Zhang Jin Mao Xuefang Wang Xiupin Wang Qi Zhang Wen Zhang Peiwu Li | 2018 | Oil Crop Science2018，3，4： | 0 |

| 14 | Optical engineering of infrared PbS CQD photovoltaic cells for wireless optical power transfer systems显示文摘Infrared photovoltaic cells(IRPCs)have attracted considerable attention for potential applications in wireless optical power transfer(WOPT)systems.As an efcient fber-integrated WOPT system typically uses a 1550 nm laser beam,it is essential to tune the peak conversion efciency of IRPCs to this wavelength.However,IRPCs based on lead sulfde(PbS)colloidal quantum dots(CQDs)with an excitonic peak of 1550 nm exhibit low short circuit current(Jsc)due to insufcient absorption under monochromatic light illumination.Here,we propose comprehensive optical engineering to optimize the device structure of IRPCs based on PbS CQDs,for 1550 nm WOPT systems.The absorption by the device is enhanced by improving the transmittance of tin-doped indium oxide(ITO)in the infrared region and by utilizing the optical resonance efect in the device.Therefore,the optimized device exhibited a high short circuit current density of 37.65 mA/cm^(2)under 1 sun(AM 1.5G)solar illumination and 11.91 mA/cm^(2)under 1550 nm illumination 17.3 mW/cm^(2).Furthermore,the champion device achieved a record high power conversion efciency(PCE)of 7.17%under 1 sun illumination and 10.29%under 1550 nm illumination.The PbS CQDs IRPCs under 1550 nm illumination can even light up a liquid crystal display(LCD),demonstrating application prospects in the future. | Mengqiong Zhu Yuanbo Zhang Shuaicheng Lu Zijun Wang Junbing Zhou Wenkai Ma Ruinan Zhu Guanyuan Chen Jianbing Zhang Liang Gao Jiancan Yu Pingqi Gao Jiang Tang | 2023 | Frontiers of Optoelectronics2023，16，2： | 0 |
| 15 | Equivalent Pi-Network Model of Lossy and Dispersive Coupled Transmission Lines显示文摘An equivalent circuit representation is presented for a set of coupled transmission lines. An ap-proximation of the hyperbolic secant function allows a simple derivation of a staged model that accounts for the complex frequency dependent parameters. The model converts the T-ladder network into a π-network with controlled sources. The equivalent circuit based approach presented here is not only intriguing but also enhances the computed accuracy and efficiency. Numerical simulations verify the accuracy of this approach for both time and frequency domain responses. | Wenjun Zhang Ruinan Chang | 2012 | Tsinghua Science and Technology2012，17，1： | 0 |
