High spin-wave propagation length consistent with low damping in a metallic ferromagnet

August 31, 2019
Author(s)
L. Flacke, L. Liensberger, Matthias Althammer, Hans Huebl, Stephan Gepr?ags, Katrin Schultheiss, Aleksandr Buzdakov, T. Hula, H. Schultheiss, Eric R. Edwards, Hans Nembach, Justin Shaw, Rudolf Gross, M. Weiler
We report ultralow intrinsic magnetic damping in Co 25Fe 75 heterostructures, reaching the low 10 -4 regime at room temperature. By using a broadband ferromagnetic resonance technique in out-of-plane geometry, we extracted the dynamic magnetic properties

Classifying single-qubit noise using machine learning

August 30, 2019
Author(s)
Travis L. Scholten, Yi-Kai Liu, Kevin Young, Robin Blume-Kohout
As quantum information processors (QIPs) grow more sophisticated, characterizing their behavior becomes harder. Larger QIPs have more properties that need to be characterized, and inventing a new quantum characterization, verification, and validation (QCVV

Compact total irradiance monitor: Flight demonstration

August 30, 2019
Author(s)
Dave Harber, John H. Lehman, Nathan A. Tomlin, Christopher Yung, Malcolm White, Zach Castleman, Ginger Drake, Samuel Van Dreser, Nat Farber, Karl Heurman, Joel Rutkowski, Alan Sims, Jacob Sprunck, Cameron Straatsma, Isaac Wanamaker, Wengang Zheng, Greg Kopp, P. Pilewskie, Michelle Stephens
The long-term balance between Earth's absorption of solar energy and emission of radiation to space is a fundamental climate measurement. Total solar irradiance (TSI) has been measured from space, uninterrupted, for the past 40 years via a series of

Indistinguishable photons from deterministically integrated single quantum dots in heterogeneous GaAs/Si3N4 quantum photonic circuits

August 30, 2019
Author(s)
Peter Schnauber, Anshuman Singh, Johannes Schall, Suk I. Park, Jin Dong Song, Sven Rodt, Kartik Srinivasan, Stephan Reitzenstein, Marcelo I. Davanco
Silicon photonics enables the integration of multi-functional quantum networks on a chip. Inclusion of quantum emitters acting as on-demand single-photon source or photon non-linearity is highly desirable to boost scalability and functionality. Towards

Josephson Junctions for Metrology Applications

August 30, 2019
Author(s)
Samuel P. Benz
The Josephson effect has revolutionized voltage metrology [1-5] and, together with the quantum Hall effect for resistance and atomic clocks for time and frequency, has enabled measurement standards based on quantum effects. Quantum standards produce

Thermal Stability of Titanium Contacts to MoS2

August 30, 2019
Author(s)
Huairuo Zhang, Albert Davydov, Leonid A. Bendersky, Keren M. Freedy, Stephen J. McDonnell
Thermal annealing of Ti contacts is commonly implemented in the fabrication of MoS2 devices however its effects on interface chemistry have not been previously reported in the literature. In this work, the thermal stability of titanium contacts deposited

Large Outdoor Fires and the Built Environment (LOF&BE): Summary of Workshop at Interflam 2019

August 29, 2019
Author(s)
Samuel L. Manzello, Sara McAllister, Sayaka Suzuki, Raphaele Blanchi, Elsa Pastor, Ronchi Enrico
A workshop of the permanent working group, sponsored by the International Association for Fire Safety Science (IAFSS), entitled Large Outdoor Fires and the Built Environment(LOF&BE) was held from 2:00 pm to 4:00 pm on Sunday June 30, 2019. The workshop was

Practical Guidelines to 13C-based NMR Metabolomics

August 29, 2019
Author(s)
Arthur S. Edison, Adrien Le Guennec, Frank Delaglio, Eriks Kupce
We present an overview of 13C-based NMR metabolomics. At first glance, the low sensitivity of 13C relative to 1H NMR might seem like too great an obstacle to use this approach. However, there are several advantages to 13C NMR, whether samples can be

Scientific Statement Classification over arXiv.org

August 29, 2019
Author(s)
Bruce R. Miller, Deyan Ginev
We introduce a new classification task for scientific statements and release a large-scale dataset for supervised learning. Our resource is derived from a machine- readable representation of the arXiv.org collection of preprint articles. We explore fifty

Contactless Resonant Cavity Dielectric Spectroscopic Studies of Cellulosic Paper Aging

August 28, 2019
Author(s)
Mary Kombolias, Jan Obrzut, Michael T. Postek, Dianne L. Poster, Yaw S. Obeng
The current analytical techniques for characterizing printing and graphic arts substrates, particularly those used to date and to authenticate provenance, are largely ex situ and destructive. This limits the amount of data that can be captured from an

Integrated Operations Management for Distributed Manufacturing

August 28, 2019
Author(s)
Timothy A. Sprock, Michael E. Sharp, William Z. Bernstein, Michael P. Brundage, Moneer M. Helu, Thomas D. Hedberg Jr.
In traditional manufacturing operations management systems, the four pillars of ISA-95 (production, quality, maintenance, inventory) are each implemented as separate software systems. Each system independently manages its own data, operational decision

Resonant X-ray Emission and Valence-band Lifetime Broadening in LiNO3

August 28, 2019
Author(s)
John T. Vinson, Terrence J. Jach, Matthias Mueller, Rainer Unterumsberger, Burkhard Beckhoff
X-ray absorption and resonant inelastic x-ray scattering measurements are carried out on lithium nitrate LiNO3. Echoing previous studies on ammonium nitrate, the σ orbitals around the nitrogen atoms exhibit a large lifetime effect. Experimentally, this is

Derived Personal Identity Verification (PIV) Credentials

August 27, 2019
Author(s)
William D. Newhouse
Federal Information Processing Standards (FIPS) Publication 201-2, “Personal Identity Verification (PIV) of Federal Employees and Contractors,” establishes a standard for a PIV system based on secure and reliable forms of identity credentials issued by the

Measurement of Oxidatively Induced DNA Damage in Caenorhabditis elegans with High-Salt DNA Extraction and Isotope-Dilution Mass Spectrometry

August 27, 2019
Author(s)
Leona D. Scanlan, Pawel Jaruga, Sanem Hosbas Coskun, Christopher Sims, Shannon Hanna, Jamie L. Almeida, David N. Catoe, Bryant C. Nelson, Miral M. Dizdar, Erdem Coskun
Caenorhabditis elegans (C. elegans) is used as a medical and systems toxicity model organism for environmental and developmental assays that include high-throughput methods and genetic studies. However, little is known about background levels of

Stress measurements in alumina by optical fluorescence: revisited

August 27, 2019
Author(s)
Robert F. Cook, Chris A. Michaels
Stress measurements in single crystal and polycrystalline alumina are revisited using a recently-developed optical fluorescence energy shift method. The method simultaneously utilizes the R1 and R2 Cr-related ruby line shifts in alumina to determine two

Screening for Next Generation Refrigerants

August 26, 2019
Author(s)
Piotr A. Domanski
The availability of refrigerants having low global warming potential (GWP) varies between different applications as it is demonstrated by four system types. Unitary air conditioning (high-pressure application) presents a particularly difficult challenge
