| 1 | Spatial and temporal distribution of Neolithic sites in coastal China:Sea level changes, geomorphic evolution and human adaption显示文摘The East China coastal plain is one of the most important Neolithic culture areas in China, where rich archaeological sites including those producing the earliest domesticated rice are observed. It is also a place where landscape has experienced dramatic evolution during the Holocene when both sea level and climate changed, such that it is an ideal place for studying human-environment interaction. This study investigated over 2000 sites of pre-history and Shang and Zhou Dynasties, with 655 of which being Neolithic ages, by using DEM and GIS methods. The results suggest that the spatial and temporal distribution of Neolithic sites has largely been controlled by landscape evolution(particularly changes in coastal line), which ultimately governed by sea level changes. During early Holocene, Neolithic sites sparsely distributed in the intermountain basins of east Zhejiang Province, far from the influence of ocean. Over the period of 9–7 ka, the coastal plain(including the shelf) was largely submerged,only the feet of low hills to the south and southwest of the study area, and islands protruding the estuary, cradled limited number of settlements with characteristic 'maritime components'. At about 7 ka, sea level rise decelerated prominently, while sediments supply in the drainage remained high value, the combination of which led to land formation and propagation. Vast space during this period facilitated the growth of settlements in both size and number. In the mean time, however, the coastal plain was vulnerable to extreme environmental events such as storms and flooding owning to its geomorphic nature, which exerted great influence on the rise and fall of Neolithic culture. | ZHENG HongBo ZHOU YouSheng YANG Qing HU ZhuJun LING GuangJiu ZHANG JuZhong GU ChunGuang WANG YingYing CAO YeTing HUANG XianRong CHENG Yue ZHANG XiaoYu WU WenXiang | 2018 | Science China Earth Sciences2018,61,2: | 7 |

| 3 | Effect of serum on PEGylated quantum dots:Cellular uptake and intracellular distribution显示文摘Protein adsorption is closely related with the interactions between nanoparticles and physiological systems,and further influences the cellular uptake and distribution of nanoparticles in cells.Although polyethylene glycol(PEG)ylation can largely reduce specific protein adsorption,some protein components in whole serum still interact with nanoparticles.In this work,PEGylated quantum dots(QDs) were used for investigating the quantitative and qualitative relationships of fetal bovine serum(FBS) and the cellular uptake/intracellular distribution in human hepatoma(HepG2) cell line.Nondenaturing polyacrylamide gel electrophoresis and two dimensional electrophoresis were used to analyze the adsorption of protein by PEGylated QDs.Quantitative cellular uptake of PEGylated QDs was determined by fluorescence activated cell sorting(FACS) with different FBS concentrations and incubating durations.The intracellular location of PEGylated QDs in HepG2 cells was observed using a confocal laser scanning microscope(CLSM) and a transmission electron microscope(TEM).This work will be helpful to understand the interaction between nanoparticles and cells with serum. | Yeting Jian Xianghui Xu Yunkun Li Zhongwei Gu | 2013 | Progress in Natural Science:Materials International2013,23,6: | 0 |
| 4 | Changes in Meteorological Information Transmission in the All-media Era显示文摘In the all-media era,in order to adapt to the transmission of different channels,the requirements for meteorological information have become increasingly high,and the display format has also undergone a huge change.To expand the effect of communication,create public opinion and hot spots,popularize meteorological knowledge,and spread meteorological disaster prevention and mitigation knowledge,it is necessary to transform original meteorological information into video pictures or recently popular short videos,small moving pictures,etc.Transforming meteorological information into graphics,video,dynamic graphics,micro-video,etc.is collectively called the visualization process of meteorological information.Therefore,meteorological information visualization is extremely urgent,and the natural visual communication production advantages of meteorological film and television will play a huge role.In this paper,some methods of visualizing meteorological information,expanding the spread of visualized meteorological information,and enhancing the transmission rate were proposed. | Yeting GU Lu HUANG Leina CHEN | 2020 | Meteorological and Environmental Research2020,11,1: | 0 |
