Impurity driven Brownian motion of solitons in elon- gated Bose-Einstein Condensates

March 7, 2017
Author(s)
Ian B. Spielman, Lauren M. Aycock, Dina Genkina, Hsin I Lu, Hilary Hurst, Victor Galitski
Solitons, spatially-localized, propagating excitations resulting from an interplay be- tween nonlinearity and dispersion, are ubiquitous in physical systems from water channels1 and oceans2 to optical fibers3 and Bose- Einstein condensates (BECs)4. For the

Labeling Requirements for Packages Labeled Using In-Store Scales

March 7, 2017
Author(s)
David A. Sefcik
In the early 1950s, it became popular for supermarkets to offer random weight packaged meats and produce using in-store scales. The Uniform Packaging and Labeling Regulation (UPLR) in NIST Handbook 130, “Uniform Laws and Regulations in the Areas of Legal

Theory of Kondo suppression of spin polarization in nonlocal spin valves

March 7, 2017
Author(s)
Kyoung-Whan Kim, Liam O'Brien, Paul A. Crowell, C. Leighton, Mark D. Stiles
We theoretically analyze contributions from the Kondo effect to the spin polarization and spin diffusion length in all-metal nonlocal spin valves. Interdiffusion of ferromagnetic atoms into the normal metal layer creates a region in which Kondo physics

A Fast Summation Method for Oscillatory Lattice Sums

March 6, 2017
Author(s)
Ryan Denlinger, Leslie Greengard, Zydrunas Gimbutas, Vladimir Rokhlin
We present a fast summation method for lattice sums of the type which arise when solving wave scattering problems with periodic boundary conditions. While there are a variety of effective algorithms in the literature for such calculations, the approach

Arbitrarily fast quantum computation with bounded energy

March 6, 2017
Author(s)
Stephen P. Jordan
One version of the energy-time uncertainty principle states that the minimum time for a quantum system to evolve from a given state to any orthogonal state is h/(4 Δ E) where Δ E is the energy uncertainty. Many subsequent works have interpreted this as

Assessment of Closed Circuit Television Digital Video Recording and Export Technologies

March 6, 2017
Author(s)
Michael Garris, Mary T. Laamanen, Craig S. Russell, Lawrence D. Nadel
The National Institute of Standards and Technology (NIST) in collaboration with the Federal Bureau of Investigation (FBI) conducted research to define and recommend an interoperable data solution to assist law enforcement in acquiring and analyzing digital

Expanding lipidome coverage using LC-MS/MS data-dependent acquisition with automated exclusion list generation

March 6, 2017
Author(s)
John Bowden, Jeremy P. Koelmel, Nicholas M. Kroeger, Emily L. Gill, Candice Z. Ulmer, Rainey E. Patterson, Richard A. Yost, Timothy J. Garrett
Untargeted omics analyses aim to comprehensively characterize biomolecules within a biological system. Changes in the presence or quantity of these biomolecules can indicate important biological perturbations, such as those caused by disease. With current

Fair Resource Allocation in the Citizen Broadband Radio Service Band

March 6, 2017
Author(s)
Anirudha Sahoo
The Citizen Broadband Radio Service (CBRS) band has three tiers of users. The General Authorized Access (GAA) has the lowest priority and operates without a license. A Spectrum Access System (SAS) is responsible for managing spectrum among the users. The

Fast Sodium Ionic Conduction in Na 2 B 10 H 10 -Na 2 B 12 H 12 Pseudo-Binary Complex Hydride and Application to a Bulk-Type All-Solid-State Battery

March 6, 2017
Author(s)
Koji Yoshida, Toyoto Sato, Atsushi Unemoto, Motoaki Matsuo, Tamio Ikeshoji, Terrence J. Udovic, Shin-Ichi Orimo
In the present work, we developed highly ion-conductive Na 2B 10H 10-Na 2B 12H 12 closo-borane (solid-solution) salts via mechanically ball-milling admixtures of the pure Na 2B 10H 10 and Na 2B 12H 12 components. They were characterized by XRD, Raman

Molecular Dynamics Simulation of Trimer Self-Assembly Under Shear

March 6, 2017
Author(s)
Raymond D. Mountain, Harold Hatch, Vincent K. Shen
The self-assembly of patchy trimer particles with one attractive bead and two repulsive beads is investigated with nonequilibrium molecular dynamics simulations in the presence of a velocity gradient, as would be produced by the application of a shear

Time and frequency from electrical power lines

March 6, 2017
Author(s)
Jonathan E. Hardis, Demetrios Matsakis, Blair Fonville
Due to the efforts of Henry Warren, inventor of the Telechron electric clock, electric power companies have been a source of time and frequency reference for the public for over a hundred years. However, advances in technology and changes in the electric

Towards a Digital Thread and Data Package for Metals Additive Manufacturing

March 6, 2017
Author(s)
Paul Witherell, Yan Lu, Shaw C. Feng, Duckbong Kim
Additive manufacturing (AM) has been envisioned by many as the next industrial revolution. Potential benefits of AM include the production of low-volume, customized, complicated parts/products, supply chain efficiencies, shortened time-to-market, and

3.5 GHz Environmental Sensing Capability Sensitivity Requirements and Deployment

March 5, 2017
Author(s)
Thao T. Nguyen, Anirudha Sahoo, Michael R. Souryal, Timothy Hall
Spectrum sharing in the 3.5 GHz band between commercial and government users along U.S. coastal areas depends on an Environmental Sensing Capability (ESC), a network of radio frequency sensors and a decision system, to detect the presence of incumbent

IAQ Assessments in High Performing Building

March 5, 2017
Author(s)
Kevin Teichman, Steven Emmerich, Andrew K. Persily
Despite numerous efforts to encourage good indoor air quality (IAQ) in high-performing buildings, including several building rating programs, measured IAQ performance data in high- performing buildings are limited. This presentation summarizes data that
