A System for Validating Resistive Neural Network Prototypes

July 27, 2021
Author(s)
Brian Hoskins, Mitchell Fream, Matthew Daniels, Jonathan Goodwill, Advait Madhavan, Jabez J. McClelland, Osama Yousuf, Gina C. Adam, Wen Ma, Muqing Liu, Rasmus Madsen, Martin Lueker-Boden
Building prototypes of heterogeneous hardware systems based on emerging electronic, magnetic, and photonic devices is an increasingly important area of research. On the face of it, the novel implementation of these systems, especially for online learning

Real-Time Low-Frequency Oscillations Monitoring

July 26, 2021
Author(s)
Bin Hu, Hamid Gharavi
A major concern for interconnected power grid systems is low frequency oscillation, which limits the scalability and transmission capacity of power systems. Un-damped, or poorly-damped oscillations will lead to undesirable conditions or even a catastrophic

Field-induced dehydration and optimal ionic escape paths for C2N membranes

June 11, 2021
Author(s)
Miroslav Barabash, William Gibby, Dmitry Luchinsky, Binquan Luan, Alexander Smolyanitsky, Peter McClintock
Most analytic theories describing electrostatically driven ion transport through water-filled nanopores assume that the corresponding permeation barriers are bias-independent. While this assumption may hold for sufficiently wide pores under infinitely

Extrapolation And Interpolation Strategies For Efficiently Estimating Structural Observables As a Function Of Temperature And Density

October 8, 2020
Author(s)
Jacob I. Monroe, Harold Wickes Hatch, Nathan NMN Mahynski, M. Scott Shell, Vincent K. Shen
Thermodynamic extrapolation has previously been used to predict arbitrary structural observables in molecular simulations at temperatures (or relative chemical potentials in open- system mixtures) different from those at which the simulation was performed

Towards Measurement of Advanced Mobile Manipulator Performance for Assembly Applications

August 11, 2020
Author(s)
Roger V. Bostelman, YaShian Li-Baboud, Soocheol Yoon, Mili Shah, Omar Y. Aboul-Enein
Advanced mobile manipulators offer the manufacturing industry the potential of a highly flexible system to perform precision assembly tasks where the environment and the system are subject to uncertainties. Developing precision performance measurement

The Certification of Standard Reference Material 1979: Powder Diffraction Line Profile Standard for Crystallite Size Analysis

July 31, 2020
Author(s)
James Cline, Marcus Mendenhall, Joseph J. Ritter, David R. Black, Albert Henins, John E. Bonevich, Pamela S. Whitfield, James J. Filliben
This rather long-standing project has resulted in a National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) for the analysis of crystallite size from a consideration of powder diffraction line profile broadening. It consists

Inter-Kramers Transitions and Spin-Phonon Couplings in a Lanthanide-Based Single-Molecule Magnet

April 6, 2020
Author(s)
Duncan H. Moseley, Shelby E. Stavretis, Zhenhua Zhu, Mei Guo, Craig Brown, Mykhaylo Ozerov, Yongqiang Cheng, Luke L. Daemen, Rachael Richardson, Gary Knight, Komalavalli Thirunavukkuarasu, Anibal J. Ramirez-Cuesta, Jinkui Tang, Zi-Ling Xue
Spin-phonon coupling plays a critical role in magnetic relaxation in single-molecule magnets (SMMs) and molecular qubits. Yet, few studies of its nature have been conducted. Phonons here refer to both intermolecular and intramolecular vibrations. In the

BEES: Bayesian Ensemble Estimation from SAS

August 6, 2019
Author(s)
Samuel Bowerman, Joseph E. Curtis, Joseph Clayton, Emre H. Brookes, Jeff Wereszczynski
Many biomolecular complexes exhibit a flexible ensemble of conformations in solution in order to conduct their biological function. Small angle scattering (SAS) measurements are a popular method for characterizing these flexible molecules due to their

Quantifying Macroeconomic Resilience Dividends in Cedar Rapids

July 17, 2019
Author(s)
Juan F. Fung, Jennifer F. Helgeson, Cheyney M. O'Fallon, David H. Webb, Harvey Cutler
Cedar Rapids, Iowa offers a unique case study in planning for increased resilience. In 2008, Cedar Rapids experienced severe flooding. Rather than simply rebuilding, the city of Cedar Rapids is investing in a resilient flood control system, as well as in

Certification of SRM 2497: Standard Reference Concrete for Rheological Measurements

April 22, 2019
Author(s)
Nicos Martys, Max A. Peltz, William L. George, Blaza Toman, Edward J. Garboczi, Chiara Ferraris
Rotational rheometers are commonly used to determine the rheological properties of fluids such as viscosity and yield stress [Fer12]. Manufacturers generally recommend the use of a standard oil of known viscosity to verify that the instrument is operating

Energy-level statistics in strongly disordered systems with power-law hopping

July 16, 2018
Author(s)
Paraj T. Bhattacharjee, Victor L. Quito, Sergey V. Syzranov
Motivated by neutral excitations in disordered electronic materials and systems of trapped ultracold particles with long-range interactions, we study energy-level statistics of quasiparticles with the power-law hopping Hamiltonian $\propto 1/r^\alpha$ in a

Synthesis and Synchrotron X-ray characterization of two 2D Hoffman related compounds [Ni(p-Xylylenediamine)nNi(CN)4] and [Ni(p-tetrafluoroxylylenediamine)nNi(CN)4]

April 24, 2018
Author(s)
Winnie K. Wong-Ng, Jeffrey T. Culp, Daniel W. Siderius, Yu-Sheng Chen
Synchrotron X-ray single crystal structure studies of two closed 2D Hofmann-type related compounds, [Ni(p-Xylyenediamine)n-tetracyanonickelate] (abbreviated as Ni-pXdam) and [Ni(tetrafluoro-p-Xylyenediamine)n-tetracyanonickelate] (abbreviated as Ni-pXdamF4

Experimental Investigation of Firebrand Accumulation Zones in Front of Obstacles

December 1, 2017
Author(s)
Samuel L. Manzello, Sayaka Suzuki
It is well accepted that as structures are exposed to wind, stagnation planes are produced around structures. Past work by the authors demonstrated for the first-time that wind-driven firebrand showers may accumulate in these stagnation planes. While those
