Efficient diffractive phase optics for electrons

September 1, 2014
Author(s)
Tyler R. Harvey, Jordan S. Pierce, Amit Agrawal, Benjamin McMorran, Peter Ercius, Martin Linck
Electron diffraction gratings can be used to imprint well-defined phase structure onto an electron beam. For example, diffraction gratings have been used to prepare electron beams with unique phase dislocations, such as electron vortex beams, which hold

Investigations of Near-Edge Ballistic Impacts on Law Enforcement Body Armor

September 1, 2014
Author(s)
Kirk D. Rice, Amanda L. Forster, Michael A. Riley, Nicholas Paulter
In 2005 and 2006, two law enforcement officer-involved shootings resulted in injuries to the officers when bullets were not stopped in the officers' body armor. In both cases, the bullets struck the officers' armor quite close to the edge of the ballistic

Software for Dielectric characterization by microwave cavity perturbation corrected for non-uniform fields*

September 1, 2014
Author(s)
Nathan D. Orloff, Jan Obrzut, Christian J. Long, Thomas F. Lam, Pavel Kabos, David R. Novotny, James C. Booth, James A. Liddle
This software package was developed to analyze microwave cavity perturbation data in order to determine material dielectric properties. Example software is provided to assist with data acquisition and organization. Specifically, it is de-signed to be used

Rbm24a and Rbm24b are required for normal somitogenesis

August 29, 2014
Author(s)
Samantha D. Maragh
We recently demonstrated that the gene encoding the RNA binding motif protein 24 (Rbm24)¬¬ is expressed during mouse cardiogenesis, and determined the developmental requirement for its zebrafish homologs Rbm24a and Rbm24b during cardiac development. We
