Framework for Standardization of Simulation Integrated Production Planning

June 15, 2016
Author(s)
Deogratias Kibira, Guodong Shao, Bjoern J. Johansson
Production planning is a complex problem that is typically decomposed into decisions carried out at different control levels. Production planning methods employed often assume a static environment; therefore, the plans developed may not be feasible if shop

Low Helium Permeation Cells for Atomic Microsystems Technology

June 15, 2016
Author(s)
Argyrios Dellis, Shah Vishal, Elizabeth A. Donley, Svenja A. Knappe, John E. Kitching
The miniaturization of instruments and sensors based on laser-cooled atoms is hindered by the large pumps needed to maintain the vacuum requirements. A significant source of vacuum contamination is the permeation of gases through the walls of the chamber

Quantum spin dynamics and entanglement generation with hundreds of trapped ions

June 15, 2016
Author(s)
Justin G. Bohnet, Brian C. Sawyer, Joseph W. Britton, Michael L. Wall, A M. Rey, Michael S. Foss-Feig, John J. Bollinger
Quantum simulation of spin models can provide insights into a variety of hard problems, including the competition between entanglement and decoherence in open quantum systems. Trapped ions are an established platform for quantum simulation, but only

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
