| 1 | The impacts of climate change on the Neolithic cultures of Gansu-Qinghai region during the late Holocene Megathermal显示文摘Holocene Megathermal 被划分成早、中间、迟了的时期,各由于他们改变趋势的不同气候在过时的文化上有不同影响。这研究基于在金海·莱克,记录的环境进化信息的比较分析黄土高原和 Zoige 和 Gansu-Qinghai 区域的过时的地点的空间分发的西方的边。结果证明早、中间的时期向温暖、潮湿在 Gansu-Qinghai 区域作为主要扇区与农业支持了过时的文化的开发,而且, Yangshao 文化繁荣的一个全盛时期出现了。Holocene 在 Gansu-Qinghai 区域在 5.9 ka BP 在冷气候事件以后进入了迟了的时期。后来,气候开始变得冷。然而,在 5.84.2 ka BP,相对稳定的温暖、潮湿的气候在这个区域为过时的年龄的 Majiayao 文化的发展创造了条件,因此,它的文化遗产地点的分发向高高度和高纬度膨胀了。从 4.2 ka BP 向前,气候变得冷、干燥,它在 Gansu-Qinghai 区域的过时的文化上有重要影响,在 4.2 ka BP 附近在文化人物和 Qijia 文化的空间分发导致一个戏剧的变化。在以后一将近 300 年冷、干燥的时期,统一过时的耕作文化完全崩溃了。以后,畜牧和耕作和地区性的多重文化的一个工业部门形成了,并且最终导致了原始社会并且开始一个使文明的社会的结束。 | LIU Fenggui ZHANG Yili FENG Zhaodong HOU Guangliang ZHOU Qiang ZHANG Haifeng | 2010 | Journal of Geographical Sciences2010，20，3： | 18 |
| 2 | High-Resolution Records of the Holocene Paleoenvironmental Variation Reflected by Carbonate and Its Isotopic Compositions in Bosten Lake and Response to Glacial Activities显示文摘The Early Holocene paleoclimate in Bosten Lake on the northern margin of the Tarim Basin, southern Xinjiang, is reconstructed through an analysis of a 953 cm long core (BSTC2000) taken from Bosten Lake. Multiple proxies of this core, including the mineral components of carbonate, carbonate content, stable isotopic compositions of carbonate, Ca/Sr, TOC and C/N and C/S of organic matter, are used to reconstruct the climatic change since 8500 a B.P. The chronology model is made by nine AMS 14C ages of leaves, seeds and organic matter contained in two parallel cores. The climate was cold and wet during 8500 to 8100 a B.P. Temperature increased from 8100 to 6400 a B.P., the climate was warm and humid, and the lake expanded. The lake level was highest during this stage. Then from 6400 to 5100 a B.P., the climate became cold and the lake level decreased slightly. During the late mid-Holocene, the climate was hot and dry from 5100 to 3100 a B.P., but there was a short cold period during 4400 to 3800 a B.P. At this temporal interval, a mass of ice and snow melting water supplied the lake at the early time and made the lake level rise. The second highest lake level stage occurred during 5200 to 3800 a B.P. The climate was cool and wet during 3100 to 2200 a B.P., when the lake expanded with decreasing evaporation. The lake had the last short-term high level during 3100 to 2800 a B.P. After this short high lake level period, the lake shrank because of the long-term lower temperature and reduced water supply. From 2200 to 1200 a B.P., the climate was hot and dry, and the lake shrank greatly. Although the temperature decreased somewhat from 1200 a B.P. to the present, the climate was warm and dry. The lake level began to rise a little again, but it did not reach the river bed altitude of the Konqi River, an outflow river of the Bosten Lake. | ZHANG Chengjun ZHENG Mianping Alexander PROKOPENKO Steffen MISCHKE GOU Xiaohui YANG Qili ZHANG Wanyi FENG Zhaodong | 2009 | Acta Geologica Sinica(English Edition)2009，83，6： | 10 |
| 3 | Pollen-recorded climate changes between 13.0 and 7.0 ^(14)C ka BP in southern Ningxia,China显示文摘A pollen record from Haiyuan section in the southern part of Ningxia revealed a detailed history of vegetation variation and associated climate changes during the period from^13.0 to^7.0 14 C ka BP.A steppe landscape under a moderately dry(and probably cool)condition(~12.7-~12.1 14 C ka BP)was replaced by a coniferous forest dominating the landscape under a generally wet climate from^12.1 to ~11.01 4C ka BP.This generally wet period,corresponding to the European B?lling/All?rod period,can be divided into three stages:a cool and wet stage between^12.1 and^11.4 14 C ka BP,a mild and rela- tively dry stage between^11.4 and^11.2 14 C ka BP,and a mild and wet stage between^11.2 and^11.0 14 C ka BP.The coniferous forest-dominated landscape was then deteriorated into steppe landscape (~11.0-~10.6 14 C ka BP)and further into a desert steppe landscape from^10.6 to^9.8 14 C ka BP,being correspondent to the European Younger Dryas period.After a brief episode of a cool and wet climate (~9.8-~9.6 14 C ka BP),a relatively mild and dry condition prevailed during the early Holocene(~9.6- ~7.6 14 C ka BP)and then a warm and humid climate started the mid-Holocene(~7.6-~7.2 14 C ka BP). | SUN AiZhi MAYuZhen FENG ZhaoDong LI Fei WU HuiNing | 2007 | Chinese Science Bulletin2007，52，8： | 6 |
| 4 | Spatiotemporal variations of Zr/Rb ratio in three last interglacial paleosol profiles across the Chinese Loess Plateau and its implications for climatic interpretation显示文摘The ratio of Zirconium to Rubidium (Zr/Rb) is suggested to be a better proxy for the East Asian winter monsoon strength than the widely-used grain size distribution. The rationale for the Zr/Rb proxy relies on the following assumptions: (1) Grain size fractionating characteristics during eolian dust transport should be archived in the Zr/Rb ratio records and this assumption is based on the premise that Zr is preferentially enriched in coarser grain size fraction while Rb tend to be enriched in finer grain size fraction; and (2) post-depositional weathering does not change the Zr/Rb ratio due to the immobility of these two elements. To examine these two assumptions, three last interglacial paleosols (S1) from Dingxi, Tianshui and Lantian, along a NW-SE transect across the Chinese Loess Plateau, were geo- chemically investigated. Our results show that the Rb concentration exhibits an increasing trend along the NW-SE transect both in the paleosol (S1) and the measured portions of the loess units (L1 and L2), being supportive to the assumption that Rb is enriched in the fine particles. But we also found that Rb loss did occur to some extent in the three profiles, contradicting to the presumption of Rb immobility during pedogenic processes. The Zr concentration exhibits an expected decreasing trend in the measured portions of the loess units and an unexpected increasing trend in the paleosol along the NW-SE transect. Moreover, the ratios of Zirconium to Hafnium (Zr/Hf) show different variation patterns between interglacial and glacial, implying that Zr-bearing minerals and their resident grain size frac- tions are probably not identical during interglacial and glacial. Thus, the assumption that Zr is enriched in coarse grain size fraction can no longer hold. We conclude that the final Zr/Rb value is not only de- pendent on grain size sorting processes but also on post-depositional alteration and source prove- nance. Under enhanced chemical weathering, especially when chemical index of alteration (CIA) is greater than 65, the Zr/Rb value loses its validity to be a reliable proxy for the winter monsoon strength. In addition, all the Zr/Rb value is constrained above 1.7, a minimum which is definitely modulated by all the three aforementioned factors. | WANG HaiBin LIU LianYou FENG ZhaoDong | 2008 | Chinese Science Bulletin2008，53，9： | 6 |
| 5 | Vegetation and climate changes during the last 8660 cal.a BP in central Mongolia,based on a high-resolution pollen record from Lake Ugii Nuur显示文摘Based on modern pollen studies and reliable chronology of nine AMS 14C dates, a detailed history of vegetation and climate changes during the past 8660 cal. a BP was reconstructed by a high-resolution pollen record from Ugii Nuur in central Mongolia. Poaceae-steppe dominated the study area and the climate was mild and semi-humid before 7800 cal. a BP with a noticeable cool and humid interval at 8350―8250 cal. a BP. Xerophytic plant increased and the climate became warm and dry gradually since 7800 cal. a BP. From 6860 to 3170 cal. a BP, semi-desert steppe expanded, suggesting a prolonged warm and dry climate. Between 3170 and 2340 cal. a BP, regional forest steppe expanded whereas semi-desert steppe retreated, indicating the climate became cool and wet gradually and the humidity reached the maximum at the end of this stage. From 2340 to 1600 cal. a BP, a general cool and wet climate prevailed. And the climatic instability increased after 1600 cal. a BP. Review of regional pub-lished palaeoclimatic records implies that the mid-Holocene dry climate might have prevailed in vast areas from central Mongolia to arid areas of northwest China. Pollen-based climate reconstruction for UG04 core was well correlated with the result of climate model on Central Asia by Bush. In addition, several abrupt climatic events (cool and wet) were found and some could be broadly compared with the cool events in Atlantic. | WANG Wei MA YuZhen FENG ZhaoDong MENG HongWei SANG YanLi ZHAI XinWei | 2009 | Chinese Science Bulletin2009，54，9： | 5 |

| 7 | Quercetin promotes human epidermal stem cell proliferation through the estrogen receptor/β-catenin/c-Myc/cyclin A2 signaling pathway显示文摘Skin epidermal stem cells(EpSCs)play an important role in wound healing.Quercetin is a phytoestrogen reported to accelerate skin wound healing,but its effect on EpSCs is unknown.In this study,we investigated the effect of quercetin on human EpSC proliferation and explored the underlying mechanisms.We found that quercetin at 0.1~1μM significantly promoted EpSC proliferation and increased the number of cells in S phase.The pro-proliferative effect of quercetin on EpSCs was confirmed in cultured human skin tissue.Mechanistic studies showed that quercetin significantly upregulated the expressions ofβ-catenin,c-Myc,and cyclins A2 and E1.Inhibitor forβ-catenin or c-Myc significantly inhibited quercetin-induced EpSC proliferation.Theβ-catenin inhibitor XAV-939 suppressed quercetin-induced expressions ofβ-catenin,c-Myc,and cyclins A2 and E1.The c-Myc inhibitor 10058-F4 inhibited the upregulation of c-Myc and cyclin A2 by quercetin.Pretreatment of EpSCs with estrogen receptor(ER)antagonist ICI182780,but not the G protein-coupled ER1 antagonist G15,reversed quercetin-induced cell proliferation and upregulation ofβ-catenin,c-Myc,and cyclin A2.Collectively,these results indicate that quercetin promotes EpSC proliferation through ER-mediated activation ofβ-catenin/c-Myc/cyclinA2 signaling pathway and ER-independent upregulation of cyclin E1 and that quercetin may accelerate skin wound healing through promoting EpSC proliferation.As EpSCs are used not only in clinic to treat skin wounds but also as seed cells in skin tissue engineering,quercetin is a useful reagent to expand EpSCs for basic research,skin wound treatment,and skin tissue engineering. | Zhaodong Wang Guangliang Zhang Yingying Le Jihui Ju Ping Zhang Dapeng Wan Qiang Zhao Guangzhe Jin Hao Su Jinwei Liu Jiaxuan Feng Yi Fu Ruixing Hou | 2020 | Acta Biochimica et Biophysica Sinica2020，52，10： | 3 |

| 13 | Generalized stability criterion for controlling solidification segregation upon twin-roll casting显示文摘Macro-and micro-segregation formed upon twin-roll casting(TRC)can be inherited from sub-rapid solid-ification to solid-state transformation,even to plastic deformation,thus deteriorating drastically mechan-ical properties of as-produced thin sheets.Although many works focusing mainly on controlling fields of thermal,concentration and convection have been reported,how to control artificially and quantitatively the segregation using a theoretical connection between processing parameters and solidification models,has not been realized,yet.Regarding it,a systematical framework integrating non-equilibrium dendritic growth and overall solidification kinetics with the TRC parameters,was constructed applying a general-ized stability(GS)conception deduced from transient thermodynamic driving force△G^(t)and transient ki-netic energy barrier Q_(eff)^(t)evolving upon solidification.Departing from this framework considering synergy of thermodynamics and kinetics(i.e.,thermo-kinetic synergy),a criterion of high△G^(t)-high GS guaranteed that the macro(i.e.,the centerline)and the micro(i.e.,the edge)segregation can be suppressed by in-creasing△G^(t)and GS at the beginning and the ending stage of sub-rapid solidification,respectively.This typical thermo-kinetic combination producing the microstructure can be inherited into the plastic de-formation,as reflected by corresponding strength-ductility combinations.This work realized quantitative controlling of TRC by a theoretical connection between processing parameters and solidification models,where,an optimization for sub-rapid solidification segregation using the GS conception including△G^(t)and Q_(eff)^(t)has been performed. | Pan Wu Yubing Zhang Jiaqi Hu Shaojie Song Yong Li Huiyuan Wang Guo Yuan Zhaodong Wang Shizhong Wei Feng Liu | 2023 | Journal of Materials Science & Technology2023，，3： | 1 |
