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

Baseline Tailor User Guide

Author(s)
Joshua Lubell
This guide describes how to use Baseline Tailor, a software tool for navigating the United States Government's Cybersecurity Framework and for tailoring the National Institute of Standards and Technology Special Publication 800-53 Revision 4 security

Direct imaging of coexisting ordered and frustrated sublattices in artificial ferromagnetic quasicrystals

April 25, 2016
Author(s)
Barry Farmer, Vinayak Bhat, Andrew L. Balk, Eric Teipel, Nathan Smith, John Unguris, D.J. Keavney, Todd Hastings, L .E. De Long
Quasicrystals are rarely found in nature and are difficult to grow in the laboratory, but exhibit unique physical properties resulting from their signature long-range structural order without periodic translational symmetry. Magnetic interactions in

Electronic Nature of the Lock-in Magnetic Transition in CeXAl 4 Si 2

April 25, 2016
Author(s)
J. Gunasekera, Leland Harriger, A. Dahal, A. Maurya, T.W. Heitmann, Steven M.T. Disseler, A. Thamizhavel, S. Dhar, D. J. Singh, D. K. Singh
We have investigated the underlying magnetism in newly discovered single crystal Kondo lattices CeXAl 4Si 2, where X = Rh, Ir. We show that the compound undergoes an incommensurate-to- commensurate magnetic transition at Tc = 9.19 K (10.75 K in Ir). The

Measuring the Usability and Security of Permuted Passwords on Mobile Platforms

April 25, 2016
Author(s)
Kristen K. Greene, John M. Kelsey, Joshua M. Franklin
Password entry on mobile devices significantly impacts both usability and security, but there is a lack of usable security research in this area, specifically for complex password entry. To address this research gap, we set out to assign strength metrics

Optical Spintronics in Organic-Inorganic Perovskites Photovoltaics

April 25, 2016
Author(s)
Junwen Li, Paul M. Haney
Organic-inorganic halide CH 3NH 3PbI 3 solar cells have attracted enormous attention in recent years due to their remarkable power conversion efficiency. These materials should exhibit interesting spin-dependent properties as well, owing to the strong spin

Synchrotron X-Ray Microbeam Diffraction Measurements of Full Elastic Long Range Internal Strain and Stress Tensors in Commercial-Purity Aluminum Processed by Multiple Passes of Equal-Channel Angular Pressing

April 23, 2016
Author(s)
Thien Q. Phan, Lyle E. Levine, I-Fang Lee, Jonathan Z. Tischler, Ruqing Xu, Yi Huang, Terrance G. Langdon, Michael E. Kassner
Synchrotron X-ray microbeam diffraction was used to measure the full elastic long range internal strain and stress tensors of low dislocation density regions within the submicrometer grain/subgrain structure of equal-channel angular pressed (ECAP) AA1050

Guidelines for the Creation of Interoperable Software Identification (SWID) Tags

April 22, 2016
Author(s)
David A. Waltermire, Brant Cheikes, Larry Feldman, Gregory A. Witte
This report provides an overview of the capabilities and usage of software identification (SWID) tags as part of a comprehensive software lifecycle. As instantiated in the International Organization for Standardization/International Electrotechnical
