THE RELEVANCE OF DOSE-FRACTIONATION IN TOMOGRAPHY OF RADIATION-SENSITIVE SPECIMENS
收藏 引用
ULTRAMICROSCOPY 1995年 第3期60卷 357-373页
作者: MCEWEN, BF DOWNING, KH GLAESER, RM UNIV CALIF BERKELEY LAWRENCE BERKELEY LABSDIV LIFE SCIBERKELEYCA 94720 UNIV CALIF BERKELEY DEPT MOLEC & CELL BIOLBERKELEYCA 94720
It is commonly assumed that the number of projections required for single-axis tomography precludes its application to most beam-labile specimens. However, Hegerl and Hoppe have pointed out that the total dose require... 详细信息

Multiframe particle tracking in intravital imaging: defining Lagrangian coordinates in the microcirculation
收藏 引用
BIOTECHNIQUES 2006年 第5期41卷 597-601页
作者: Ravnic, Dino J. Tsuda, Akira Turhan, Aslihan Pratt, Juan P. Huss, Harold T. Zhang, Yu-Zhong Mentzer, Steven J. Harvard Univ Sch Med Boston MA USA Harvard Univ Sch Publ Hlth Boston MA 02115 USA Mol Probes Invitrogen Eugene OR USA
The cellular composition of the microcirculation creates blood flow that can be unsteady and nonuniform. To obtain information about nonuniform cellular trajectories, we describe in vivo imaging techniques that provid... 详细信息

Stereo-4-D reconstruction and animation from living fluorescent specimens
收藏 引用
BIOTECHNIQUES 1998年 第6期24卷 1006-+页
作者: Mohler, WA White, JG Univ Wisconsin Mol Biol Lab Madison WI 53706 USA
We present a novel approach to the viewing and analysis of 4-dimensional (4-D) data sets recorded from live fluorescent samples. With stereo-4-D reconstructions, the observer manipulates a rotatable projection of the ... 详细信息

A Background Color Scheme for Piper Plots to Spatially Visualize Hydrochemical Patterns
收藏 引用
GROUNDWATER 2014年 第1期52卷 2-6页
作者: Peeters, Luk CSIRO Land & Water Groundwater Hydrol Program Glen Osmond SA 5064 Australia
The combination of ternary diagrams of cations and anions with a central diamond graph make the Piper plot very useful in visualizing groundwater chemistry datasets. One of the major drawbacks is that it is hard to li... 详细信息
