Phase-resolved ferromagnetic resonance using heterodyne detection method

April 28, 2016
Author(s)
Seungha Yoon, Hau Jian Liu, Robert D. McMichael
This paper describes a phase-resolved ferromagnetic resonance (FMR) measurement using a heterodyne method. Spin precession is driven by microwave fields and detected by 1550 nm laser light that is modulated at a frequency slightly shifted with respected to

Rapid Fabrication of Poly(DL-lactide) Nanofiber Scaffolds with Tunable Degradation for Tissue Engineering Applications by Air-brushing

April 28, 2016
Author(s)
Adam M. Behrens, Jeffrey J. Kim, Nathan A. Hotaling, Jonathan Seppala, Peter Kofinas, Wojtek J. Tutak
Polymer nanofiber based materials have been widely investigated for use as tissue engineering scaffolds. While promising, these materials are typically fabricated through techniques that require significant time or cost. Here we report a cost effective

Report on Post-Quantum Cryptography

April 28, 2016
Author(s)
Lidong Chen, Stephen P. Jordan, Yi-Kai Liu, Dustin Moody, Rene C. Peralta, Ray A. Perlner, Daniel C. Smith-Tone
In recent years, there has been a substantial amount of research on quantum computers - machines that exploit quantum mechanical phenomena to solve mathematical problems that are difficult or intractable for conventional computers. If large-scale quantum

Status of the Liquid Deuterium Cold Neutron Source for the NIST Research Reactor

April 28, 2016
Author(s)
Robert E. Williams, Michael Middleton, Paul Kopetka, J. Michael Rowe, Paul C. Brand
The NBSR is a 20 MW research reactor operated by the NIST Center for Neutron Researcher (NCNR) as a neutron source providing beams of thermal and cold neutrons for research in materials science, fundamental physics and nuclear chemistry. A large, 55 cm

Vibrational Modes of Multilayered Ceramic Capacitors

April 28, 2016
Author(s)
Kirsten L. Peterson, Ward L. Johnson, Sudook A. Kim, Paul R. Heyliger
Micron-scale spacing of interleaved electrodes and high-dielectric ceramics in multilayer ceramic capacitors (MLCCs) provide exceptionally high capacitances in small volumes. This has led to MLCCs being the preferred type of capacitor in a wide range of

STEP File Analyzer User's Guide (Version 3)

April 27, 2016
Author(s)
Robert R. Lipman
This guide describes how to use the STEP File Analyzer, a software tool that analyzes and generates a spreadsheet from a STEP (STandard for the Exchange of Product model data) file. The spreadsheets simplify inspecting information in the STEP file at an

"Perpendicular laser cooling with a rotating wall potential in a Penning trap"

April 26, 2016
Author(s)
Joseph W. Britton, Justin G. Bohnet, John Bollinger, Steven B. Torrisi
We investigate the impact of a rotating wall potential on perpendicular laser cooling in a Penning ion trap. By including energy exchange with the rotating wall, we extend previous Doppler laser cooling theory and show that low perpendicular temperatures

Predictive Blood Chemistry Parameters for Pansteatitis-Affected Mozambique Tilapia (Oreochromis mossambicus)

April 26, 2016
Author(s)
John Bowden, Theresa M. Cantu, Robert W. Chapman, Stephen E. Somerville, Matthew P. Guillette, Hannes Botha, Andre Hoffman, Wilmien Luus-Powell, Willem J. Smit, Jeffrey Lebepe, Jan Myburgh, Danny Govender, Jonathan Tucker, Louis J. Guillette Jr., Ashley S. Boggs-Russell
One of the largest river systems in South Africa, the Olifants River, has witnessed significant changes in water quality due to anthropogenic activities. Since 2005, there have been various “outbreaks” of the inflammatory disease pansteatitis in several

Shape Retrieval of Non-Rigid 3D Human Models

April 26, 2016
Author(s)
Afzal A. Godil, David Pickup
3D models of humans are commonly used within computer graphics and vision, and so the ability to distinguish between body shapes is an important shape retrieval problem. We extend our recent paper which provided a benchmark for testing non-rigid 3D shape

A universal Moire effect and application in x-Ray phase-contrast imaging

April 25, 2016
Author(s)
Houxun Miao, Alireza Panna, Andrew A. Gomella, Eric E. Bennett, sami Znati, Lei Chen, Han Wen
A moiré pattern is created by superimposing two black-and-white or gray-scale patterns of regular geometry, such as two sets of evenly spaced lines. We observed an analogous effect between two transparent phase masks in a light beam which occurs at a
