A Direct Precision Measurement of the Intergalactic Lyman-α Opacity at 2 ≤ Z ≤ 4.2
We directly measure the evolution of the intergalactic Lyman-α effective optical depth, τeff , over the redshift range 2 ≤ z ≤ 4.2 from a sample of 84 high-resolution, high-signal-to-noise quasar spectra obtained with the ESI and HIRES spectrographs on Keck, and with the MIKE spectrograph on Magellan. This represents an improvement over previous analyses of the Lyα forest from highresolution sp...
متن کاملOpacity Peeling for Direct Volume Rendering
The most important technique to visualize 3D scalar data, as they arise e.g. in medicine from tomographic measurement, is direct volume rendering. A transfer function maps the scalar values to optical properties which are used to solve the integral of light transport in participating media. Many medical data sets, especially MRI data, however, are difficult to visualize due to different tissue ...
متن کاملGingival Thickness Assessment: Visual versus Direct Measurement
Background and Aim: Several methods have been suggested to measure gingival thick-ness. This study aimed to assess the reliability of visual assessment of facial gingival biotype of maxillary and mandibular teeth with or without using a periodontal probe in comparison with direct measurement. Materials and Methods: Sixty-seven healthy patients (25 women and 42 men) with a total of 100 hopele...
متن کاملAccuracy of xenon CT measurement of cerebral blood flow.
In recent years, quantitative determination of cerebral blood flow (CBF) by xenon-enhanced CT has become an increasingly important research and clinical tool. Concurrently, the possibility that inhalation of stable xenon in the concentrations required for this procedure might itself alter CBF also has received increasing attention. Several studies [1-6] have examined this problem by using vario...
