| 1 | Spatial Interaction Between the Industrial Undertaking Capacity and Global Value Chain Position of East Asian Countries显示文摘A comprehensive understanding of the spatial interaction between the industrial undertaking capability and the position of the global value chain of the 12 East Asian countries is conducive to strengthening regional cooperation, gaining a say in foreign trade and becoming the dominant player in the global division of labor system. The article reveals the operating rules of the interaction between the industrial undertaking capacity and the global value chain position of East Asian countries by calculating the Global Moran Index(Moran’s I), coupling coordination degree and other indicators. The results show that: in time, the values of industrial undertaking capacity and the positions of global value chain in East Asian countries showed a sustained and stable growth trend, and have a consistent trend of change. Spatially, both of the two indexes had significant positive spatial correlation, with Moran’s I showing an ‘inverted U’pattern, and the spatial aggregation distribution of global value chain position lagged behind the spatial aggregation distribution of industrial undertaking capacity by one year. In terms of spatial coupling coordination, the coupling coordination values of the two indicators show a steady upward trend. Combined with the comparative advantage of each country, this paper provides suggestions for promoting the positions of Chinese and other East Asian industries in the global value chain from the perspectives of enhancing independent innovation capability and upgrading industrial structure. | ZHU Binbin CHI Fangyuan DU Lei | 2021 | Chinese Geographical Science2021，31，1： | 3 |
| 2 | Ultrahigh energy density and improved discharged efficiency in bismuth sodium titanate based relaxor ferroelectrics with A-site vacancy显示文摘Novel A-site deficient(1-x-y)Bi_(0.5)Na_(0.5)TiO_(3-x)BaTiO_(3-y)Bi_(0.2)Sr_(0.7)TiO_(3)lead-free relaxor ferroelectrics have been explored for energy storage property.Particularly slim polarization hysteresis(P-E)loops are observed in 0.655Bi_(0.5)Na_(0.5)TiO_(3)-0.065BaTiO_(3)-0.28Bi_(0.2)Sr_(0.7)□_(0.1)TiO_(3)(6.5BNBT-BST)at ambient temperature resulting in a giant recoverable energy density(W_(rec)=1.5 J cm^(-3))and extremely high efficiency(η=90%)at 100 kV cm^(-1),which are closed related to the track of P-E loops.As the addition of Bi_(0.2)Sr_(0.7)TiO_(3)(BST)content,the ergodic relaxor phase becomes dominant with dynamic polar nanoregions attributed to the absence of ferroelectric domain in the relaxor phase.Furthermore,the recoverable energy density exhibits small variation in elevated temperature where the depressed polarization is compensated by almost hysteresis free loops(ηup to 97%).The achievement of these characteristics in P-E loops provides that Bi_(0.2)Sr_(0.7)TiO_(3)tailoring by A-site vacancies is a potential route when designing new relaxor ferroelectrics for energy-storage applications. | Xiao Liu Jing Shi Fangyuan Zhu Huiling Du Tangyuan Li Xiangchun Liu Hai Lu | 2018 | Journal of Materiomics2018，4，3： | 3 |
| 3 | Characteristics of soil organic carbon andtotal nitrogen storages for differentland-use types in Central Yunnan Plateau显示文摘Two-factor analysis of variance and redundancy analysis were used to analyze the characte-ristics of soil organic carbon total nitrogen storage in garden land,forestland,grassland,farmland,and bare land in the Dachunhe watershed of Jinning District,Kunming City,Yunnan Province,China.The effects of the soil organic carbon,total nitrogen stratification ratio,soil physical and chemical factors on the storage characteristics of organic carbon and total nitrogen of different land-use types were analyzed.The results show that the rates of carbon and nitrogen stratification in soil from 0-20 cm and 40-60 cm of the same land-use types differed are statistically significant(P<0.05).The organic carbon and total nitrogen stratification ratio SR1 of garden land soil are 38.5%and 25.3%,respectively,which are higher than SR^(2).The soil organic carbon and total nitrogen stratification ratio SR^(2) of different land-use types are greater than SR1.There are statistically significant differences in the SR^(2) soil organic carbon and total nitrogen stratification ratios(P<0.05).Soil organic carbon and total nitrogen storage of diffe-rent land-use types gradually decrease with increasing soil depth,with the maximum soil organic carbon and total nitrogen storage in the 0-20 cm soil layer.Soil organic carbon and total nitrogen sto-rage at the same soil depth are significantly different(P<0.05).Soil organic carbon and total nitrogen storage in the garden land are greater than those in the other land-use types.Soil organic carbon and total nitrogen storage in 0-20 cm garden land are 4.96 and 3.19 times than those in bare land,respectively;soil organic carbon and total nitrogen storage are explained by 93.66%and 1.53%in redundancy analysis RDA1 and RDA2,respectively.All physicochemical factors except Available Phosphorus and pH are statistically significance with carbon and nitrogen storage(P<0.05).Soil cationic exchange capacity,Available Phosphorus,C/N ratio,and Moisture Content are positively correlated with organic carbon and total nitrogen storage.In contrast,soil Bulk Density is negatively correlated with organic carbon storage and total nitrogen storage.Available Phosphorus,C/N ratio,and Moisture Content are the main factors promoting soil organic carbon and total nitrogen accumulation. | SHEN Fangyuan TUO Yunfei WANG Qian WANG Fei ZHENG Yang DU Wenjuan XIANG Ping | 2022 | 排灌机械工程学报2022，40，5： | 1 |

| 6 | Designed fabrication of mesoporous silica-templated self-assembled theranostic nanomedicines显示文摘Theranostic nanosystems that integrate diagnosis and therapy have garnered increasing attention for personalized medicine.The integration of the versatile nanoparticles to fabricate self-assembled theranostic nanomedicines becomes increasingly important in current medical research.Mesoporous silica nanoparticles(MSN)with their highly attractive physicochemical properties and favorable morphological attributes represent ideal templates for the controlled assembly and integration of functional nanomaterials to fabricate self-assembled theranostic nanomedicines.The rationally designed combination strategy and heterostructure will improve the overall bioavailability and preserve the unique property of each nanocomponent.In this review,the cutting-edge strategies for the designed fabrication of MSN-templated self-assembled nanomedicines are summarized.We categorize MSN-based nanomedicines by their unique heterostructures,including core-shell,yolk-shell,core-satellite,heterodimer and core-shell-satellite structures,and discuss the controlled assembly approaches as well as the intriguing applications for disease theranostics.Finally,a perspective on the challenges in the clinical translation of self-assembled theranostic nanomedicines is highlighted. | Fangyuan Li&Daishun Ling Yang Du Zheng Chen Ji Young Lee Peihua Lin Fan Xia Yunan Guan Fangyuan Li Daishun Ling | 2021 | Science China Chemistry2021，64，2： | 0 |
| 7 | Responses of a resident group to an outsider in the blue-breasted quail: A paradigm for studying social resettlement of dispersers显示文摘Dispersal is an individual life-history trait that can influence the ecological and evolutionary dynamics of both the source and recipient populations.Current studies of animal dispersal have paid little attention to how the responses of residents in a recipient population affect the social resettlement of dispersers into a new habitat.We addressed this question in the blue-breasted quail Synoicus chinensis by designing an outsider introduction experiment to simulate a scenario of interaction between residents and dispersers.In the experiment,we introduced an unfamiliar quail into a group of 3 differently ranked residents and then examined their behavioral responses to the arrival of the outsider.We found that all residents made negative responses by pecking at the outsider to maintain their pecking order,in which high-ranked residents displayed significantly greater intensity than those of lower ranks.This result highlighted that adverse behavioral responses of residents would prevent outsiders from obtaining hierarchical dominance in the recipient group.Moreover,the residents’sex ratio,their relative ages to the outsiders,and whether outsiders counter-pecked at the residents all influenced the probability of outsiders prevailing against the residents.Those outsiders that displayed counter-peck courage were more likely to gain higher dominance and hence resettle into the recipient group successfully.Our findings suggest that resident groups may impose a selection among dispersers via adverse behavioral responses.Therefore,social factors that can influence the resettlement step of dispersers in a new habitat should be accounted for in future studies of animal dispersal. | Shumei Zi Lifang Gao Xiaoxue Chen Qian Wang Fangyuan Liu Jianchuan Li Bo Du | 2023 | Current Zoology2023，69，3： | 0 |
| 8 | Cytochrome P450s in algae:Bioactive natural product biosynthesis and light-driven bioproduction显示文摘Algae are a large group of photo synthetic organisms responsible for approximately half of the earth’s total photosynthesis.In addition to their fundamental ecological roles as oxygen producers and as the food base for almost all aquatic life,algae are also a rich source of bioactive natural products,including several clinical drugs.Cytochrome P450 enzymes(P450s) are a superfamily of biocatalysts that are extensively involved in natural product biosynthesis by mediating various types of reactions.In the post-genome era,a growing number of P450 genes have been discovered from algae,indicating their important roles in algal life-cycle.However,the functional studies of algal P450s remain limited.Benefitting from the recent technical advances in algae cultivation and genetic manipulation,the researches on P450s in algal natural product biosynthesis have been approaching to a new stage.Moreover,some photoauto trophic algae have been developed into 'photo-bioreactors' for heterologous P450s to produce high-value added pharmaceuticals and chemicals in a carbon-neutral or carbon-negative manner.Here,we comprehensively review these advances of P450 studies in algae from 2000 to 2021. | Shanmin Zheng Jiawei Guo Fangyuan Cheng Zhengquan Gao Lei Du Chunxiao Meng Shengying Li Xingwang Zhang | 2022 | Acta Pharmaceutica Sinica B2022，12，6： | 0 |
