1SHRIMP U-Pb dating for a K-bentonite bed in the Tieling Formation,North China显示文摘A SHRIMP U-Pb zircon age of 1437±21 Ma was obtained for a recently discovered K-bentonite bed in the Tieling Formation,situated northeast of Beijing at the boundary between Liaoning and Hebei provinces,on the northern margin of the North China Craton(NCC).The SHRIMP U-Pb age places Tieling Formation near the end of the Calymmian Period of the early Mesoproterozoic Era.In addition,a SHRIMP U-Pb zircon date of 1372±18 Ma was acquired for K-bentonite beds in the overlying,dark-shale-dominated Xiamaling Formation from the same location northeast of Beijing.This date assigns a similar Mid-Mesoproterozoic(Ectasian Period) age for the Xiamaling Formation,as have previously determined dates from other sections northwest of Beijing.These dates indicate that the Tieling and Xiamaling formations,as well as the related succession in the eastern part of the Yanshan Mountains,represented by the well-known Meso-to Neoproterozoic standard section in Jixian,can be correlated well with sections northwest of Beijing in the western part of the Yanshan Mountains.In other words,the boundary between the Calymmian and Ectasian periods in the northern parts of the NCC is marked by the unconformity between the Tieling and Xiamaling formations in the northern NCC.This boundary was previously ascribed to the 'Qinyu Orogeny' and thought to be of Grenville age.In this regard,the conventional 'Qinyu Orogeny' should now be regarded as a short-lived regional uplift during Early Mesoproterozoic time,rather than a result from the Grenvillian assembly of the NCC to the Rodinia Supercontinent(~1.0 Ga).SU WenBo LI HuaiKun HUFF W D ETTENSOHN F R ZHANG ShiHong ZHOU HongYing WAN YuSheng 2010Chinese Science Bulletin2010,55,29:30
2冠状动脉内皮功能障碍患者循环MOTS-c水平下调显示文摘MOTS-c是一种新发现的线粒体衍生肽,其在调节代谢稳态中起作用。该研究旨在研究在没有显著冠状动脉结构性病变的患者中循环MOTS-c水平是否也与内皮功能障碍相关。方法:纳入无冠状动脉结构性病变的复发性心绞痛并接受冠状动脉造影和内皮功能检测的患者40例。Qin Q Delrio S Wan J Jay Widmer R Cohen P Lerman LO Lerman A 刘青 叶鹏 2018中华高血压杂志2018,26,2:14
3Hepatitis B virus x gene and cyanobacterial toxins promote aflatoxin B_1-induced hepatotumorigenesis in mice显示文摘瞄准:估计黄麴毒素的结合的角色 B1 (AFB1 ) , cyanobacterial 毒素(cyanotoxins ) ,和肝炎 B (HBV ) 在 hepatotumorigenicity 的 x 基因。方法:( ip )带 HBV x 基因和他们的野类型的同窝出生的人的 One-week-old 动物 intraperitoneally 与也被注射单个剂量的 AFB1 [ 6 mg/kg 体重( bw )],重复剂量 cyanotoxins ( microcystin-LR 或在榴状, 10 microg/kg bw 每周一次为 15 wk ), DMSO (车辆控制)独自一个,或 AFB1 一个星期以后由 cyanotoxins 列在后面,并且在 24 和 52 wk 被牺牲处理以后。结果:AFB1 在 29 中的 13 个导致了肝肿瘤(44.8%) 在 52 wk 的转基因的老鼠处理以后,显著地比在野类型的老鼠(13.3%) 更经常。这有效差量没在 24-wk 学习被显示出。与 AFB1 暴露相比独自一个, MC-LR 并且在榴状在导致的 AFB (1 ) 的发生产出近似 3 褶层和 6 褶层增加在在 24 wk 的野类型的动物的肝肿瘤分别地。HBV x 基因进一步没提高与合作暴露联系到 AFB1 和 cyanotoxins 的风险。与一个 MC-LR-dosed 野类型的鼠标的异常,没有肝肿瘤在在 24 wk 独自与 cyanotoxins 对待的鼠标被观察。既不对待 DMSO 的转基因的老鼠也不他们的野类型的同窝出生的人在甚至多达 52 wk 有与 hepatotumorigenesis 相关的病理学的改变。结论:HBV x 基因并且在榴状支持导致的 AFB (1 ) 的发展肝肿瘤。到 AFB1 和 MC-LR 的合作暴露趋于相对暴露在 24 wk 提高肝肿瘤的风险到他们之一。hepatotumorigenesis 上的 AFB1, cyanotoxins 和 HBVx 的结合的效果在 24 wk 是弱的。Min Lian Ying Liu Shun-Zhang Yu Geng-Sun Qian Shu-Guang Wan Kenneth R Dixon 2006World Journal of Gastroenterology2006,12,19:14

6Efficient photon coupling from a diamond nitrogen vacancy center by integration with silica fiber显示文摘A central goal in quantum information science is to efficiently interface photons with single optical modes for quantum networking and distributed quantum computing.Here,we introduce and experimentally demonstrate a compact and efficient method for the low-loss coupling of a solid-state qubit,the nitrogen vacancy(NV)center in diamond,with a single-mode optical fiber.In this approach,single-mode tapered diamond waveguides containing exactly one high quality NV memory are selected and integrated on tapered silica fibers.Numerical optimization of an adiabatic coupler indicates that near-unity-efficiency photon transfer is possible between the two modes.Experimentally,we find an overall collection efficiency between 16%and 37%and estimate a single photon count rate at saturation above 700 kHz.This integrated system enables robust,alignment-free,and efficient interfacing of single-mode optical fibers with single photon emitters and quantum memories in solids.Rishi N Patel Tim Schröder Noel Wan Luozhou Li Sara L Mouradian Edward H Chen Dirk R Englund 2016Light(Science & Applications)2016,5,1:2
