1Argo floats revealing bimodality of large-scale mid-depth circulation in the North Atlantic显示文摘Analysis of Argo float trajectories at 1 000 m and temperature at 950 m in the North Atlantic between November 2003 and January 2005 demonstrates the existence of two different circulation modes with fast transition between them. Each mode has a pair of cyclonic-anticyclonic gyres. The difference is the location of the cyclonic gyre. The cyclonic gyre stretches from southeast to northwest in the first mode and from the southwest to the northeast in the second mode. The observed modes strongly affect the heat and salt transport in the North Atlantic. In particular, the second mode slows down the westward transport of the warm and saline water from the Mediterranean Sea.CHU Peter C IVANOV Leonid M MELNICHENKO Oleg V LI Rongfeng 2008Acta Oceanologica Sinica2008,27,2:4

7New Observation of Na2 4^3∑g^+ State by Pulsed Perturbation Facilitated Optical-Optical Double Resonance Spectroscopy显示文摘用微扰增强双共振对钠分子4~3∑_g^+态33900~35200 cm^(-1)的65个振转能级进行了实验观测。以往用连续激光双共振方法只看到低振动能级,用脉冲激光双共振和检测解离产物的方法只观测到高振动能级。获得的新数据填补了以往数据的空缺。综合v=0~31能级所有数据,拟合出一套分子常数,计算出RKR势能曲线。主要分子常数为:T_e=32127.090 cm^(-1),ω_e=121.1099(0.20720)cm^(-1),B_e=0.116287(0.0002300)cm^(-1),Re=3.551 (?)。还对J. Chem. Phys.108,7707 (1998)中RKR势能曲线的一个错误进行了纠正。Zheng Chen Cheng-zhe Cui Yao-ming Liu Li Li V. B. Sovkov V. S. Ivanov 2006Chinese Journal of Chemical Physics2006,19,1:0
8Dose-efficient scanning Compton X-ray microscopy显示文摘The highest resolution of images of soft matter and biological materials is ultimately limited by modification of the structure,induced by the necessarily high energy of short-wavelength radiation.Imaging the inelastically scattered X-rays at a photon energy of 60 keV(0.02 nm wavelength)offers greater signal per energy transferred to the sample than coherent-scattering techniques such as phase-contrast microscopy and projection holography.We present images of dried,unstained,and unfixed biological objects obtained by scanning Compton X-ray microscopy,at a resolution of about 70 nm.This microscope was realised using novel wedged multilayer Laue lenses that were fabricated to sub-ångström precision,a new wavefront measurement scheme for hard X rays,and efficient pixel-array detectors.The doses required to form these images were as little as 0.02%of the tolerable dose and 0.05%of that needed for phase-contrast imaging at similar resolution using 17 keV photon energy.The images obtained provide a quantitative map of the projected mass density in the sample,as confirmed by imaging a silicon wedge.Based on these results,we find that it should be possible to obtain radiation damage-free images of biological samples at a resolution below 10 nm.Tang Li JLukas Dresselhaus Nikolay Ivanov Mauro Prasciolu Holger Fleckenstein Oleksandr Yefanov Wenhui Zhang David Pennicard Ann-Christin Dippel Olof Gutowski Pablo Villanueva-Perez Henry N.Chapman Saša Bajt 2023Light(Science & Applications)2023,12,6:0
