Precision vs Accuracy Dilemma in Point-Based Rigid-Body Registration

March 23, 2017
Author(s)
Marek Franaszek, Geraldine S. Cheok
The purpose of a registration is to find the transformation between two coordinate frames: working frame (from which 3D data are transformed) and destination frame (to which the data are transformed). In point-based, rigid-body registration, the

Superconducting Optoelectronic Circuits for Neuromorphic Computing

March 23, 2017
Author(s)
Jeffrey M. Shainline, Sonia M. Buckley, Richard P. Mirin, Sae Woo Nam
We propose a hybrid semiconductor-superconductor hardware platform for the implementation of neural networks and large-scale neuromorphic computing. The platform combines semiconducting few-photon light-emitting diodes with superconducting-nanowire single

AP Selection Algorithm with Adaptive CCAT for Dense Wireless Networks

March 22, 2017
Author(s)
Ye Na Kim, Munsuk Kim, SuKyoung Lee, David W. Griffith, Nada T. Golmie
Wireless Local Area Networks (WLANs)-enabled devices are now everywhere and their rapid spread has created dense deployment environments. For such dense WLANs, the High Efficiency WLAN Study Group was formed, and as an extension of their activity, effort

Reduced Bimolecular Recombination in Blade-Coated, High-Efficiency, Small-Molecule Solar Cells

March 22, 2017
Author(s)
Sebastian Engmann, Hyun W. Ro, Andrew A. Herzing, Dean M. DeLongchamp, Chad R. Snyder, Lee J. Richter, Adam J. Barito, David J. Gundlach
The full benefit of emerging solution deposited photovoltaic devices requires development of processes compatible with high speed manufacturing. Extensive studies of the lab-to-fab challenge have been performed on polymer donor based organic photovoltaics

Steady-state spin synchronization through the collective motion of trapped ions

March 22, 2017
Author(s)
Athreya Shankar, John Cooper, Justin G. Bohnet, Murray Holland, John Bollinger
Ultranarrow-linewidth atoms coupled to a lossy optical cavity mode synchronize, i.e. develop correlations, and exhibit steady-state superradiance when continuously repumped. This system displays rich collective physics and promises metrological

Reference Correlation for the Viscosity of Carbon Dioxide

March 21, 2017
Author(s)
Arno D. Laesecke, Chris D. Muzny
A comprehensive database of experimental and computed data for the viscosity of carbon dioxide (CO2) was compiled and a new reference correlation was developed. Literature results based on an ab initio potential energy surface were the foundation of the

Chiral magnetoresistance in Pt/Co/Pt zigzag wires

March 20, 2017
Author(s)
Kyoung-Whan Kim, Yuxiang Yin, Dong-Soo Han, June-Seo Kim, Lavrijsen Reinoud, Kyung-Jin Lee, Seo--Won Lee, Hyun-Woo Lee, Henk Swagten, Bert Koopmans
The Rashba effect leads to a chiral rotation of conduction spins while the Dzyaloshinskii-Moriya interaction (DMI) fixes the chirality of the profile of local spins. We predict that these two spin systems interact with each other via s-d exchange, and

Frontiers of Characterization and Metrology for Nanoelectronics: 2017

March 20, 2017
Author(s)
Erik M. Secula, David G. Seiler
The 2017 International Conference on Frontiers of Characterization and Metrology for Nanoelectronics (FCMN) has the goal of bringing together scientists and engineers interested in all aspects of the characterization and measurement technology needed for

Structural Polymorphism in "Kesterite" Cu 2 ZnSnS 4 : Raman Spectroscopy and First-principles Calculations Analysis

March 20, 2017
Author(s)
Mirjana NMN Dimitrievska, Federica Boero, Alexander P. Litvinchuk, Simona Delsante, Gabriella Borzone, Alejandro Perez-Rodriguez, Victor Izquierdo-Roca
This work presents a comprehensive analysis of the structural and vibrational properties of the kesterite Cu 2ZnSnS 4 (CZTS, I-4 space group) as well as its polymorphs with the space group P-42c and P-42m, from both experimental and theoretical point of

Validation of Robotics for Antenna Measurements

March 18, 2017
Author(s)
Jeffrey R. Guerrieri
This paper presents recent measurements using the newly developed Configurable Robotic Millimeter-Wave Antenna (CROMMA) facility by the Antenna Metrology Lab at the National Institute of Standards and Technology (NIST). NIST set out to develop an antenna

A Radio Frequency Radiation Reverberation Chamber Exposure System for Rodents

March 17, 2017
Author(s)
Perry F. Wilson, John M. Ladbury, Galen H. Koepke, Capstick Myles, Niels Kuster, Sven Kuhn, Veronica Berdinas-Torres, Yijian Gong, David McCormick, James Gauger, Ronald Melnick
In this paper we present the novel design features, their technical implementation, and an evaluation of the radio frequency (RF) exposure systems developed for the National Toxicology Program (NTP) of the National Institute of Environmental Health

Efficient Simulation of Secondary Fluorescence via NIST DTSA-II Monte Carlo

March 17, 2017
Author(s)
Nicholas Ritchie
Secondary fluorescence, the final term in the familiar matrix correction triumvirate Z·A·F, is the most challenging for Monte Carlo models to simulate. In fact, only two implementations of Monte Carlo models commonly used to simulate electron probe x-ray
