An Long Term Evolution (LTE) Device-to-Device module for ns-3

June 14, 2016
Author(s)
Richard A. Rouil, Fernando Cintron, Aziza Ben Mosbah, Samantha Gamboa Quintiliani
In this paper, we provide an overview of the on-going implementation of a 3rd Generation Partnership Program (3GPP) Proximity Services (ProSe) module in ns-3 to enable the performance evaluation of device-to-device (D2D) discovery and communication in Long

Identification of novel N-glycosylation sites at non-canonical protein consensus motifs

June 14, 2016
Author(s)
Mark S. Lowenthal, Kiersta S. Davis, Lisa E. Kilpatrick, Catherine A. Mouchahoir, Karen W. Phinney
N-glycosylation is well known to occur at asparagine residues in the canonical consensus sequence N-X-S/T, but has also been identified at a small number of N-X-C motifs including the Asn491 residue of human serotransferrin. Here we report additional novel

On challenges in the uncertainty evaluation for time-dependent measurements

June 14, 2016
Author(s)
Sascha Eichstadt, Volker Wilkens, Andrew Dienstfrey, Paul D. Hale, Ben Hughes, Charles Jarvis
The measurement of quantities with time-dependent values is a common task in many areas of metrology. Although well established techniques are available for the analysis of such measurements, serious scientific challenges remain to be solved to enable

Precision measurement of the radiative beta decay of the free neutron

June 14, 2016
Author(s)
Jeffrey S. Nico, Kevin J. Coakley, Maynard S. Dewey, Thomas R. Gentile, Hans P. Mumm, Alan Keith Thompson, M J. Bales, R. Alarcon, C. D. Bass, E J. Beise, H Breuer, Jim Byrne, R L. Cooper, B. O'Neill, F E. Wietfeldt, T E. Chupp
The theory of quantum electrodynamics predicts that a continuous spectrum of photons is emitted in the beta decay of the free neutron in addition to a proton, an electron, and an antineutrino. We report the first precision test of the shape of the photon

Standards for cell line authentication and beyond

June 14, 2016
Author(s)
Jamie L. Almeida, Kenneth D. Cole, Anne L. Plant
Different genomic technologies have been applied to cell line authentication, but only one method (short tandem repeat profiling) has been the subject of a comprehensive standard (ASN-0002). Here we discuss the power of this document, and why standards

Arrays of individually controlled ions suitable for two-dimensional quantum simulations

June 13, 2016
Author(s)
Manuel Mielenz, Henning Kalis, Matthias Wittemer, Frederick Hakelberg, Roman Blain, Peter Maunz, Dietrich Leibfried, Tobias Schaetz
A custom-built and precisely controlled quantum system may o ffer access to a fundamental understanding of another, less accessible system of interest. A universal quantum computer is currently out of reach, but an analog quantum simulator (AQS) that makes

Invited Article: MiniTimeCube

June 13, 2016
Author(s)
Hans P. Mumm
We present the development of the miniTimeCube (mTC), the world’s smallest neutrino detector. The mTC is a multipurpose detector, aiming to detect not only neutrinos but also fast/thermal neutrons and gammas. Potential applications include the

RANS and Hybrid LES/RANS Simulations of Flow over a Square Cylinder

June 11, 2016
Author(s)
Jianghua Ke, DongHun Yeo
Unsteady RANS (URANS) and Hybrid LES/RANS (specifically IDDES) simulations were conducted to numerically investigate the velocity field around, and pressures distribution and forces over a square cylinder immersed in a uniform, steady oncoming flow with

Estimating t-way Fault Profile Evolution During Testing

June 10, 2016
Author(s)
Raghu N. Kacker, David R. Kuhn
Empirical studies have shown that most software interaction faults involve one or two variables interacting, with progressively fewer triggered by three or more, and no failure has been reported involving more than six variables interacting. This paper

Numerical modeling of heat transfer in steel-concrete composite slabs

June 10, 2016
Author(s)
Jian Jiang, Joseph A. Main, Jonathan M. Weigand, Fahim Sadek
This paper presents detailed and reduced-order numerical modeling of heat transfer in composite floor slabs with profiled steel decking. The detailed modeling approach represents the concrete slab with solid elements and the steel decking with shell

Observation of Strong Reflection of Electron Waves Exiting a Ballistic Channel at Low Energy

June 10, 2016
Author(s)
Jason Campbell, Jason Ryan, Kin P. Cheung, David J. Gundlach, Changze Liu, Canute I. Vaz, Richard G. Southwick III, Anthony S. Oates, Ru Huang
Wave scattering by a potential step is a nearly ubiquitous concept. Thus, it is surprising that theoretical treatments of ballistic transport in nanoscale devices, from quantum point contacts to ballistic transistors, assume no reflection even when the

A Helmholtz Energy Equation of State for Sulfur Dioxide

June 9, 2016
Author(s)
Kehui Gao, Jiangtao Wu, Penggang Zhang, Eric Lemmon
A Helmholtz energy equation of state with independent variables of temperature and density was developed for sulfur dioxide (SO2) based on thermodynamic property data from the literature. The equation of state is valid from the triple-point temperature of

Certification of Standard Reference Material 1878b Respirable Alpha Quartz

June 9, 2016
Author(s)
David R. Black, Marcus H. Mendenhall, Pamela S. Whitfield, Donald A. Windover, Albert Henins, James J. Filliben, James P. Cline
The National Institute of Standards and Technology (NIST) certifies a suite of Standard Reference Materials (SRMs) to address specific aspects of the performance of X-ray powder diffraction instruments. This report describes SRM 1878b, the third generation

Wide-field quantitative imaging of tissue microstructure using high-frequency structured light

June 9, 2016
Author(s)
David McClatchy III, Elizabeth Rizzo, wendy wells, Jeeseong C. Hwang, keith paulson, Brian Pogue, Stephen Kanick
Sub-diffusive structured light imaging has been shown to accurately and quantitatively map the reduced scattering coefficient and the phase function backscatter parameter in a wide-field geometry. This study shows the first the experimental imaging of

XAFS Data Interchange: A single spectrum XAFS data file format

June 9, 2016
Author(s)
Bruce D. Ravel, M. Newville
We propose a standard data format for the interchange of XAFS data. The XAFS Data Interchange (XDI) standard is meant to encapsulate a single spectrum of XAFS along with relevant metadata. XDI is a text-based format with a simple syntax which clearly
