The Ultraviolet-to-mid-infrared Spectral Energy Distribution of Weak Emission Line Quasars
We present Spitzer Space Telescope photometry of 18 Sloan Digital Sky Survey (SDSS) quasars at 2.7 ≤ z ≤ 5.9 which have weak or undetectable high-ionization emission lines in their rest-frameExpand

Studies of Hard and Soft Tissue Elemental Compositions in Mice and Rats Subjected to Simulated Microgravity
Microgravity has profound effects on skeletal as well as other body systems. To investigate the effect of microgravity, we have used a NASA validated Hind‐limb suspension (HLS) animal model ofExpand

Energy loss in gas lasers operating in hollow-core optical fibers
The output of solid core fiber lasers is constrained in the mid-infrared due to the absorption properties of silica. Optically pumped gas lasers can reach the mid-infrared but require long pathExpand

Optimization of negative stage bias potential for faster imaging in large-scale electron microscopy
Large-scale electron microscopy (EM) allows analysis of both tissues and macromolecules in a semi-automated manner, but acquisition rate forms a bottleneck. We reasoned that a negative bias potentialExpand
