SATE V Report: Ten Years of Static Analysis Tool Expositions

October 23, 2018
Author(s)
Aurelien M. Delaitre, Bertrand C. Stivalet, Paul E. Black, Vadim Okun, Terry S. Cohen, Athos Ribeiro
Software assurance has been the focus of the National Institute of Standards and Technology (NIST) Software Assurance Metrics and Tool Evaluation (SAMATE) team for many years.The Static Analysis Tool Exposition (SATE) is one of the team’s prominent

Transactive Energy Challenge Phase II Scenario

October 23, 2018
Author(s)
David G. Holmberg, Martin J. Burns, Steven T. Bushby, Avi M. Gopstein
The TE Challenge Phase II Scenario was developed in a multi-step process in collaboration with industry experts. The Scenario includes a common electric grid definition including attached loads and generators, weather, and reporting metrics which together

Flow fluctuations in wormlike micelle fluids

October 22, 2018
Author(s)
Paul NMN Salipante, Steven Meek, Steven D Hudson
We investigate the unstable flow of wormlike micelle solutions in pressure driven capillary flow, with a focus on the effect of entrance geometry on the fluid fluctuations. The flow is measured at different points in the capillary using particle image

Measurement and Modeling of Heterogeneous Chip-Scale Interconnections

October 22, 2018
Author(s)
Richard A. Chamberlin, Dylan F. Williams
We present precision scattering-parameter measurements of chip-to-chip connections in heterogeneous integrated circuits: indium phosphide or gallium nitride “chiplets” mounted on SiCMOS carrier chips. We demonstrate methodology, experimental results, and

Pulsed Laser Deposition Films from a Ba 2 FeMoO 6 Target onto SrTiO 3 [001]: Chemical and Magnetic Inhomogeneity

October 22, 2018
Author(s)
Daniel M. Pajerowski, Lisa J. Krayer, Brian Kirby, Brian B. Maranville, Julie Borchers, Kyeong-Won Kim, David P. Norton
We have used a combination of x-ray diffraction, atomic force microscopy, x-ray and neutron reflectivity, and x-ray photoelectron spectroscopy to investigate inhomogeneities within pulsed laser deposition, Ba 2FeMoO 6 films on SrTiO 3[001]. These results

3.5 GHz Federal Incumbent Protection Algorithms

October 21, 2018
Author(s)
Michael R. Souryal, Thao T. Nguyen, Nickolas J. LaSorte
The current standardized algorithm for U.S. federal incumbent protection in the 3.5 GHz band is sub-optimum in that it moves more commercial transmissions out of the protected channel than necessary, in most cases. This paper proposes a more efficient

Characterization of a Dual Josephson Impedance Bridge

October 21, 2018
Author(s)
Nathan Flowers-Jacobs, Blaise Jeanneret, Frederic Overney, Alain Rufenacht, Anna Fox, Paul Dresselhaus, Samuel P. Benz
This paper describes a dual Josephson impedance bridge capable of comparing any two impedances, that is, with any amplitude ratio and relative phase, over a wide range of frequency. A new, more compact, design has been achieved by mounting the two

Localization of Fe d-states in Ni-Fe-Cu alloys and implications for ultrafast demagnetization

October 20, 2018
Author(s)
Ronny J. Knut, Erna Delczeg, Justin Shaw, Hans Nembach, Patrik Grychtol, Dmitriy Zusin, Christian Gentry, Emrah Turgut, Henry C. Kapteyn, Margaret M. Murnane, Dario A. Arena, Olle Eriksson, Olof Karis, Thomas J. Silva
Ni 80Fe 20 (Py) and Py-Cu exhibit intriguing ultrafast demagnetization behavior, where the Ni magnetic moment shows a delayed response relative to the Fe [S. Mathias et al., PNAS \bf 109}, 4792 (2012)]. To unravel the mechanism responsible for this

Behavior of the Breathing Pyrochlore Lattice Ba 3 Yb 2 Zn 5 O 11 in Applied Magnetic Field

October 19, 2018
Author(s)
J. G. Rau, L. S. Wu, A. F. May, A. E. Taylor, I-Lin Liu, J. Higgins, Nicholas Butch, K. A. Ross, H. S. Nair, M. D. Lumsden, M. J. P. Gingras, A. D. Christianson
The breathing pyrochlore lattice material Ba 3Yb 2Zn 5O 11 exists in the nearly decoupled limit, in contrast to most other well-studied breathing pyrochlore compounds. Here we study the magnetic field dependent behavior of Ba 3Yb 2Zn 5O 11 at low

Long-Range Electric Field Control of Permalloy Layers in Strain-Coupled Composite Multiferroics

October 18, 2018
Author(s)
Michelle E. Jamer, Colin R. Rementer, Anthony Barra, Alexander Grutter, Kevin Fitzell, Daniel Gopman, Julie Borchers, Gregory P. Carman, Brian Kirby, Jane P. Chang
Artificial composite multiferroic materials can be created by interfacing magnetostrictive and piezoelectric materials, allowing for electric field control of magnetic properties. For multilayer device applications, addition of weakly magnetostrictive

On the scalability of parametric down-conversion for generating higher-order Fock states

October 18, 2018
Author(s)
Thomas Gerrits, Adriana Lita, Sae Woo Nam, Johannes Tiedau, Tim J. Bartley, Georg Harder, Christine Silberhorn
Spontaneous parametric down-conversion (SPDC) is the most widely-used method to generate higher-order Fock states (n>2). Yet, a consistent performance analysis from fundamental principles is missing. Here we address this problem by analyzing state fidelity

On Building Fair and Reusable Test Collections using Bandit Techniques

October 17, 2018
Author(s)
Ellen Voorhees
While test collections are a vital piece of the research infrastructure for information retrieval, constructing fair, reusable test collections for large data sets is challenging because of the number of human relevance assessments required. Various
