CERTIFICATION OF SRM 640f LINE POSITION AND LINE SHAPE STANDARD FOR POWDER DIFFRACTION

May 31, 2020
Author(s)
David R. Black, Marcus Mendenhall, Albert Henins, James Filliben, James Cline
The National Institute of Standards and Technology (NIST) certifies a suite of Standard Reference Materials (SRMs) to be used to evaluate specific aspects of instrument performance of both X-ray and neutron powder diffractometers. This report describes SRM

Comparison of Open and Solid Falling Retroreflector Gravimeters

May 29, 2020
Author(s)
Neil Ashby, Derek Van Westrum
We study whether the optical properties of a solid glass retroreflector influence the value of the acceleration of gravity $g$ determined by dropping both solid and open retroreflectors in an absolute ballistic gravimeter. The retroreflectors have

Error Estimation and Enhanced Stiffness Sensitivity in Contact Resonance Force Microscopy with a Multiple Arbitrary Frequency Lock-In Amplifier (MAFLIA)

May 29, 2020
Author(s)
Erin Flater, Arya Mugdha, Saurabh Gupta, William Hudson, Abbigail Fahrenkamp, Jason Killgore, Jesse Wilson
In contact resonance force microscopy and related dynamic atomic force microscopy methods, an accurate description of the real-time cantilever dynamics is essential to the mapping of local material properties, such as viscoelasticity, piezo response, and

Experimental investigation of structural steel beams subjected to localized fire

May 29, 2020
Author(s)
Selvarajah Ramesh, Lisa Y. Choe, Chao Zhang
This paper presents an experimental behavior of unprotected W16 × 26 steel beams subjected to localized fire. Beam specimens were either simply supported or connected to steel columns via all bolted double angle connections. Two test fires, steady or

Foundational Cybersecurity Activities for IoT Device Manufacturers

May 29, 2020
Author(s)
Michael J. Fagan, Katerina N. Megas, Karen Scarfone, Matthew Smith
Internet of Things (IoT) devices often lack device cybersecurity capabilities their customers-- organizations and individuals--can use to help mitigate their cybersecurity risks. Manufacturers can help their customers by improving how securable the IoT

Frequency Invariant Beampatterns for Wideband Synthetic Aperture Channel Sounders

May 29, 2020
Author(s)
Peter G. Vouras, Jeanne T. Quimby, Benjamin F. Jamroz, Alec J. Weiss, Rodney W. Leonhardt, Dylan F. Williams, Catherine A. Remley
This paper derives two novel frequency invariant beamformers (FIBs) for use with wideband synthetic aperture channel sounders. Results using measured data show that the choice of beam pattern can affect the amount of diffuse multipath energy received

Health Assessment Measurements Quality Assurance Program: Exercise 4 Final Report

May 29, 2020
Author(s)
Charles A. Barber, Carolyn Q. Burdette, Hugh V. Hayes, Melissa M. Phillips, Catherine A. Rimmer, Laura J. Wood, Lee L. Yu, Shaun P. Kotoski
HAMQAP was launched in collaboration with the NIH ODS in 2017. HAMQAP was established to enable laboratories to improve the accuracy of measurements in samples that represent human intake (e.g., foods, dietary supplements, tobacco) and samples that

IoT Device Cybersecurity Capability Core Baseline

May 29, 2020
Author(s)
Michael J. Fagan, Katerina N. Megas, Karen Scarfone, Matthew Smith
Device cybersecurity capabilities are cybersecurity features or functions that computing devices provide through their own technical means (i.e., device hardware and software). This publication defines an Internet of Things (IoT) device cybersecurity

Nature of the Spin Resonance Mode in CeCoIn 5

May 29, 2020
Author(s)
Yu Song, Weiyi Wang, John S. Van Dyke, Naveen Pouse, Sheng Ran, Duygu Yazici, Astrid Schneidewind, Petr Cermak, Yiming Qiu, M. B. Maple, Dirk K. Morr, Pengcheng Dai
Complex intertwined orders often emerge in strongly correlated electron materials in the vicinity of unconventional superconductivity. Superconductivity is typically optimized when such orders are suppressed, although associated fluctuations remain intense

Notes on Interrogating Random Quantum Circuits

May 29, 2020
Author(s)
Luis Brandao, Rene C. Peralta
Consider a quantum circuit that, when fed a constant input, produces a fixed-length random bit- string in each execution. Executing it many times yields a sample of many bit-strings that contain fresh randomness inherent to the quantum evaluation. When the
