John Padgette, John Bahr, Mayank Batra, Rhonda Smithbey, Lily Chen, Karen Scarfone
Bluetooth wireless technology is an open standard for short-range radio frequency communication used primarily to establish wireless personal area networks (WPANs), and has been integrated into many types of business and consumer devices. This publication

Note: A Bitter-type electromagnet for complex atomic trapping and manipulation

February 12, 2021
Author(s)
Jacob L. Siegel, Daniel Barker, James A. Fedchak, Julia Scherschligt, Stephen Eckel
We create a pair of symmetric Bitter-type electromagnet assemblies capable of producing multiple field configurations including uniform magnetic fields, spherical quadruple traps, or Ioffe-Pritchard magnetic bottles. Unlike other designs, our coil allows

A Hybrid CPU-GPU Approach to Fourier-Based Image Stitching of Optical Microscopy Images

March 3, 2013
Author(s)
Walid Keyrouz, Timothy J. Blattner, Bertrand C. Stivalet, Joe Chalfoun, Mary C. Brady, Shujia Zhou
We present a hybrid CPU-GPU approach for the Fourier-based stitching of optical microscopy images. This system achieves sub-minute stitching rates with large grids; it stitches a grid of 59x42 tiles in 26 seconds on a two-CPU (8 physical cores) & two-GPU

The Use of Antioxidants to Improve Vapor Pressure Measurements on Compounds with Oxidative Instability: Methyl Oleate with tert-Butylhydroquinone

December 19, 2016
Author(s)
Jason A. Widegren, Casey E. Beall, Audrey E. Tolbert, Tara M. Lovestead, Thomas J. Bruno
The vapor pressure (psat) of methyl oleate was measured with and without the addition of 0.2 mass % of the antioxidant stabilizer tert-butylhydroquinone (TBHQ). The measurements were made by the gas saturation method in the temperature range (303.15 to 343
