Light-Shift Suppression with Novel Variants of Adaptive Ramsey Spectroscopy

October 3, 2019
Author(s)
Moshe Shuker, Juniper Pollock, John Kitching, Elizabeth Donley, Rodolphe Boudot, V. I. Yudin, A. V. Taichenachev
We present a brief review of the rapidly growing field of autobalanced Ramsey spectroscopy followed by a detailed discussion and review of two novel techniques that were developed and tested in our laboratory: displaced frequency-jump Ramsey spectroscopy

Multipath Mitigation from FM-AM Correlation

October 3, 2019
Author(s)
Archita Hati, Craig W. Nelson
Multipath is one of the limiting factors for an accurate outdoor and indoor localization. We proposed an approach that uses a multipath mitigation derived from the undesired frequency-to- amplitude conversion of a frequency modulated (FM) signal

Social and Economic Components of Resilient Multi-Hazard Building Design

October 3, 2019
Author(s)
Katherine Johnson, Juan Fung, Siamak Sattar, Christopher Segura, Therese P. McAllister, Steven McCabe
In 2017, U.S. damages from natural hazard events exceeded $300B, suggesting that current targets for building performance do not sufficiently mitigate loss. The significant costs borne by individuals, insurers, and government do not include impacts from

Ultrathin Wetting Layer-Free Plasmonic Gold Films

October 3, 2019
Author(s)
Robert Lemasters, Cheng Zhang, Manoj Manjare, Wenqi Zhu, Junyeob Song, Sergei Urazhdin, Henri Lezec, Amit Agrawal, Hayk Harutyunyan
Ultrathin gold films are attractive for plasmonic and metamaterial devices, thanks to their useful optical and optoelectronic properties. However, deposition of ultrathin continuous Au films of few nanometer thickness is challenging and generally requires

Calibration

October 2, 2019
Author(s)
Lane C. Sander
In the context of chemical metrology, calibration is the process of relating a known quantity of an analyte to the corresponding measured instrumental response through a mathematical relationship. Calibration permits the assignment of analyte levels in

Design of an intelligent PYTHON code to run coupled and license-free finite-element and statistical analysis software for calibration of near-field scanning microwave microscopes

October 2, 2019
Author(s)
Jeffrey T. Fong, N. Alan Heckert, James Filliben, Pedro V. Marcal, Samuel Berweger, Thomas Mitchell (Mitch) Wallis, Pavel Kabos
To calibrate near-field scanning microwave microscopes (NSMM) for defect detection and characterization in semiconductors, it is common to develop a parametric finite element analysis (FEA) code to guide the microscope user on how to optimize the settings

Plastic Marine Debris Polymers in the Hawaiian Islands: Beach, Sea Surface, and Seafloor

October 2, 2019
Author(s)
Kayla C. Brignac, Melissa R. Jung, Cheryl King, Sarah-Jeanne Royer, Lauren Blickley, Megan Lamson, James Potemra, Jennifer Lynch
Identifying the polymer type of plastic marine debris is crucial for understanding sources, fate, transport, and effects of this emerging global contaminant in the environment. This is the first study to assess the polymeric differences of plastic marine

Wireless User Requirements for the Factory Workcell

October 2, 2019
Author(s)
Karl Montgomery, Richard Candell, Yongkang Liu, Mohamed Hany
Wireless communication is becoming crucial to advanced manufacturing. Industry 4.0 and Smart Manufacturing depend on networked industrial automation systems. The term Industrial Internet of Things (IIoT) has been used to describe the deployment of

Broadband Resonator-Waveguide Coupling for Efficient Extraction of Octave Spanning Microcombs

October 1, 2019
Author(s)
Gregory Moille, Qing Li, Travis Briles, Su P. Yu, Tara E. Drake, Xiyuan Lu, Ashutosh Rao, Daron Westly, Scott Papp, Kartik Srinivasan
Frequency combs spanning over an octave have been successfully demonstrated on-chip in Kerr nonlinear microresonators, thanks to their large effective nonlinearity and ability to support a suitable dispersion profile. Efficient extraction of intracavity

Feasibility Study of Compton Imaging for PGAA

October 1, 2019
Author(s)
Heather H. Chen-Mayer, Steven Brown, Hao Yang
We are developing a one-sided tomographic method for imaging prompt gamma rays, without moving the source, sample, or detector, in a standard prompt gamma activation analysis (PGAA) setting. Dual-plane pixelated CZT detectors developed from a commercial

Field-Tunable Quantum Disordered Ground State in the Triangular-Lattice Antiferromagnet NaYbO 2

October 1, 2019
Author(s)
Mitchell M. Bordelon, Eric Kenney, Chunxiao Liu, Tom Hogan, Lorenzo Posthuma, Marzieh Kavand, Yuangqi Lyu, Mark Sherwin, Nicholas Butch, Craig Brown, M. J. Graf, Leon Balents, Stephen D. Wilson
One of the simplest routes to pursuing magnets with strong quantum fluctuations that quench conventional order is via decorating a triangular lattice with antiferromagnetically coupled S=1/2 moments. As disorder and anisotropies inherent in materials

NIST Fatty Acid Quality Assurance Program 2017 Final Report

October 1, 2019
Author(s)
Bruce A. Benner Jr., Jacolin A. Murray
At the request of the National Institutes of Health’s (NIH’s) Office of Dietary Supplements (ODS) and in conjunction with the Centers for Disease Control and Prevention (CDC), in 2017 the National Institute of Standards and Technology (NIST) conducted the
