Author(s)
Jacob W. Ward, A J. Raassen, Alexander Kramida, Gillian Nave
This work presents 97 remeasured Fe V wavelengths (1200 Å to 1600 Å) and 123 remeasured Ni V wavelengths (1200 Å to 1400 Å) with uncertainties of approximately 2 mÅ. An additional 67 remeasured Fe V wavelengths and 72 remeasured Ni V wavelengths with

On Practice and Theory of Constructive Composite Geometry and Topology

November 25, 2019
Author(s)
Thomas D. Hedberg Jr., Allison Barnard Feeney, Vijay Srinivasan
This paper synthesizes a theory from industrial best practices codified in recent standards. Recent editions of ASME and ISO standards codify the evolving industrial best practices in defining and modeling the information about products made from fibrous

Voices of First Responders - Examining Public Safety Communication from the Rural Perspective

November 25, 2019
Author(s)
Kristen K. Greene, Shanee Dawkins, Mary Theofanos, Michelle P. Steves, Susanne M. Furman, Yee-Yin Choong, Sandra S. Prettyman
With the newly created Nationwide Public Safety Broadband Network (NPSBN), the public safety community has a unique opportunity to review and improve communication technology for first responders, in urban, suburban, and rural areas. Understanding the

A Nonlinear Multivariate Cryptosystem Based on a Random Linear Code

November 24, 2019
Author(s)
Daniel C. Smith-Tone, Cristina Tone
We introduce a new technique for building multivariate encryption schemes based on random linear codes. The construction is versatile, naturally admitting multiple modifications. Among these modifications is an interesting embedding modifier -- any

Augmenting Fiat Currency with an Integrated Managed Cryptocurrency

November 24, 2019
Author(s)
Peter M. Mell
In this work, we investigate how the governance features of a managed currency (e.g., a fiat currency) can be built into a cryptocurrency in order to leverage potential benefits found in the use of blockchain technology and smart contracts. The resulting

Implementing a Protocol Native Managed Cryptocurrency

November 24, 2019
Author(s)
Peter M. Mell, Aurelien M. Delaitre, Frederic J. de Vaulx, Philippe J. Dessauw
Previous work presented a theoretical model based on the implicit Bitcoin specification for how an entity might issue a cryptocurrency that mimics features of fiat currencies. Novel to this work were mechanisms by which the issuing entity could manage the

NIST Handbook 133: Checking the Net Contents of Packaged Goods (2020 Ed.)

November 24, 2019
Author(s)
Breyanna M. Blackwell, David Sefcik, Lisa Warfield
This handbook has been prepared as a procedural guide for the compliance testing of net content statements on packaged goods. Compliance testing of packaged goods is the determination of the conformance of the- results of the packaging, distribution, and

Enhancing Materials Property Prediction by Leveraging Computational and Experimental Data using Deep Transfer Learning

Author(s)
Kamal Choudhary, Dipendra Jha, Ankit Agrawal, Alok Choudhary, Wei-keng Liao, Francesca M. Tavazza, Carelyn E. Campbell
The availability of huge collections of data from DFT-computations has spurred the interest of materials scientists in applying machine learning techniques to build models for fast prediction of materials properties. Such modeling practice has helped to

Tunable quantum beat of single photons enabled by nonlinear nanophotonics

November 22, 2019
Author(s)
Qing Li, Anshuman Singh, Xiyuan Lu, John Lawall, Varun Verma, Richard Mirin, Sae Woo Nam, Kartik Srinivasan
Integrated photonics is a promising approach for scalable implementation of diverse quantum resources at the chip-scale. Here, we demonstrate the integration of two essential building blocks for quantum information science - quantum sources and frequency

On Low-Energy Tail Distortions in the Detector Response Function of X-Ray Microcalorimeter Spectrometers

We use narrow spectral lines from the X-ray spectra of various highly charged ions to measure low-energy tail-like deviations from a Gaussian response function in a microcalorimeter X-ray spectrometer with Au absorbers at energies from 650 to 3320 eV. We

Opaque Wrappers and Patching: Negative Results

November 21, 2019
Author(s)
Paul E. Black, Monika Singh
When a patch is released for buggy software, bad actors may be able to analyze the patch and create an attack on unpatched machines. A wrapper could block attacking inputs, but it, too, gives attackers critical information. An opaque wrapper hides such
