Stiff modes in spinvalve simulations with OOMMF

April 1, 2016
Author(s)
Spyridon Mitropoulos, Vassilis Tsiantos, Kyriakos Ovaliadis, Dimitris Kechrakos, Michael J. Donahue
Micromagnetic simulations are an important tool for the investigation of magnetic materials. Micromagnetic software uses various techniques to solve differential equations, partial or ordinary, involved in the dynamic simulations. Euler, Runge-Kutta, Adams

Mid-infrared molecular spectroscopy in the quantum noise limit

March 31, 2016
Author(s)
David A. Long, Adam J. Fleisher, Qingnan Liu, Joseph T. Hodges
A cavity ring-down spectrometer was used to reach the quantum noise limit in the mid-infrared spectral region. Quantum noise was observed not only in the individual ring-down decay events but also in the corresponding ensemble statistics with a magnitude

NIST Cryptographic Standards and Guidelines Development Process

March 31, 2016
Author(s)
Andrew R. Regenscheid
This document describes the principles, processes and procedures that drive cryptographic standards and guidelines development efforts at the National Institute of Standards and Technology. This document reflects public comments received on two earlier

Silicon epitaxy on H-terminated Si (100) surfaces at 250deg C

March 31, 2016
Author(s)
Xiao Deng, Pradeep N. Namboodiri, Kai Li, Xiqiao Wang, Gheorghe Stan, Alline F. Myers, Xinbin Cheng, Tongbao Li, Richard M. Silver
Silicon on silicon growth at low temperatures has become increasing important due to its use to encapsulate buried nanoscale dopant devices. The performance of atomic scale devices is fundamentally affected by the quality of the silicon matrix in which the

SOLID-STATE LIGHTING MEASUREMENT ASSURANCE PROGRAM SUMMARY WITH ANALYSIS OF METADATA

March 31, 2016
Author(s)
Carl C. Miller, Yoshihiro Ohno, Maria E. Nadal, Benjamin K. Tsai, Yuqin Zong
The National Institute of Standards and Technology (NIST) began to offer proficiency testing for Solid-State Lighting (SSL) products through a Measurement Assurance Program (MAP) in 2010. This article communicates the results of the first version of the

Thermal characteristics of temperature-controlled electrochemical microdevices

March 31, 2016
Author(s)
Nicholas M. Contento, Stephen Semancik
The development of novel, miniaturized sensing systems is driven by the demand for better and faster chemical measurements with lower power consumption and smaller sample sizes. Emerging miniature sensors, or microsensors, also offer rapid thermal and

Towards Establishing Compact Imaging Spectrometer Standards

March 31, 2016
Author(s)
David W. Allen, Elmer T. Slonecker, Ronald G. Resmini
Remote sensing science is currently undergoing a tremendous expansion in the area of hyperspectral imaging (HSI) technology. Spurred largely by the explosive growth of Unmanned Aerial Vehicles (UAV), sometimes called Unmanned Aircraft Systems (UAS), or

Using a Capability Oriented Methodology to Build Your Cloud Ecosystem

March 31, 2016
Author(s)
Michaela Iorga, Karen Scarfone
Organizations often struggle to capture the necessary functional capabilities for each cloud-based solution adopted for their information systems. Identifying, defining, selecting, and prioritizing these functional capabilities and the security components

Probing beyond the laser coherence time in optical clock comparisons

March 30, 2016
Author(s)
David B. Hume, David R. Leibrandt
We develop protocols that circumvent the laser noise limit in optical clock comparisons by synchronous probing of two clocks using phase-locked local oscillators. This allows for probe times longer than the laser coherence time, avoids the Dick effect, and

Vision experiment ii on white light chromaticity for lighting

March 30, 2016
Author(s)
Yoshihiro Ohno, Semin Oh
In response to a published discussion (Wei & Houser, 2015) on the 2013 NIST experiment on white light chromaticity for lighting (Ohno & Fein, 2013), the second experiment was conducted at NIST to determine the white light chromaticity perceived most

NIST Weather Station for Photovoltaic and Building System Research

March 29, 2016
Author(s)
Matthew Boyd
A weather station has been constructed on the Gaithersburg, Maryland campus of the National Institute of Standards and Technology (NIST) as part of a research effort to assess performance of photovoltaic and building systems. This weather station includes

Athermal avalanche in bilayer superconducting nanowire single-photon detectors

March 28, 2016
Author(s)
Varun B. Verma, Martin J. Stevens, Richard P. Mirin, Sae Woo Nam
We demonstrate that two superconducting nanowires separated by a thin insulating barrier can undergo a thermal avalanche process. In this process, Joule heating caused by a photodetection event in one nanowire and the associated production of athermal
