Alec Weiss, Joshua Kast, Rob Jones, Jeanne Quimby, Rodney Leonhardt, Benjamin Jamroz, Peter Vouras, Dylan Williams, Kate Remley
We provide the frequency response of a high multipath propagation channel using a narrow beamwidth synthetic aperture measurement technique from 26.5 - 40 GHz.

Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations

February 21, 2020
Author(s)
Ronald S. Ross, Victoria Y. Pillitteri, Kelley L. Dempsey, Mark Riddle, Gary Guissanie
The protection of Controlled Unclassified Information (CUI) resident in nonfederal systems and organizations is of paramount importance to federal agencies and can directly impact the ability of the federal government to successfully conduct its essential

A Predictive Modeling Approach to Estimating Seismic Retrofit Costs

February 20, 2020
Author(s)
Juan F. Fung, Siamak Sattar, David T. Butry, Steven L. McCabe
This paper presents a methodology for estimating seismic retrofit costs from historical data. In particular, historical retrofit cost data from FEMA 156 is used to build a predictive model to estimate retrofit costs as a function of building

Practical Guide for Inelastic Mean Free Paths, Effective Attenuation Lengths, Mean Escape Depths, and Information Depths in X-ray Photoelectron SpectroscopyInformation Depths in X-ray Photoelectron Spectroscopy

February 20, 2020
Author(s)
Cedric J. Powell
Information is provided on four terms that are used for different purposes in X-ray photoelectron spectroscopy (XPS): the inelastic mean free path (IMFP), the effective attenuation length (EAL), the mean escape depth (MED), and the information depth (ID)

Sphere Diameter Interferometry with Nanometer Uncertainty

February 20, 2020
Author(s)
Eric S. Stanfield, John R. Stoup, Michael P. Braine, Theodore D. Doiron
In this paper we present both the design details and uncertainty budget for a National Institute of Standards and Technology (NIST)-developed high-accuracy Fizeau-type interferometer specifically adapted to measurement sphere diameter. To do this, we

Grand Canonical Inverse Design of Multicomponent Colloidal Crystals

February 19, 2020
Author(s)
Nathan Mahynski, Evan Pretti, Runfang Mao, Vincent K. Shen, Jeetain Mittal
Inverse design methods are powerful computational approaches for creating colloidal systems which self-assemble into a target morphology by reverse engineering the Hamiltonian of the system. Despite this, these optimization procedures tend to yield

New Insights into Female Humpback Whale (Megaptera novaeangliae) Reproductive Endocrinology Revealed by Steroid Hormone Profile Analysis

February 19, 2020
Author(s)
Greta Dalle Luche, Ashley Boggs, John Kucklick, Jasmin Gross, Darryl Hawker, Susan Bengston Nash
The blubber steroid hormone profiles of 52 female humpback whales migrating along the east coast of Australia were investigated for possible seasonal endocrinological changes associated with reproduction. Individuals were randomly sampled in southeast

The Structure of Medium-Scale Pool Fires

February 19, 2020
Author(s)
Ryan L. Falkenstein-Smith, Kunhyuk Sung, Jian Chen, Kimberly J. Harris, Anthony P. Hamins
This report documents a series of time-averaged gas species measurements made along the centerline of methanol, ethanol, and acetone pool fires steadily burning in a quiescent environment. All gas species measurements are obtained using a Gas Chromatograph

Enhanced Dynamics of Confined Polymers near the Immiscible Polymer-Polymer Interface: Neutron Reflectivity Studies

February 18, 2020
Author(s)
Kyoung-Il Jo, Younghoon Oh, Bong June Sung, Tae-Ho Kim, Min Seop Um, Woo Jin Choi, Joona Bang, Guangcui Yuan, Sushil K. Satija, Jaseung Koo
For polymer-blend films, local dynamics in confined polymer domains tend to differ from the bulk due to significant contributions from the polymer-polymer interface. Herein, we investigated the diffusion dynamics of entangled polymer thin films confined

Forensic Handwriting Examination and Human Factors: Improving the Practice Through a Systems Approach

February 18, 2020

Vastrick, Heather E. Waltke, Emily J. Will
For some 6,000 years, humans have made an indelible mark on history through the loops, strokes, and other characters that constitute the written form of language - handwriting. The study of handwriting is also an important part of forensic science. By

Implementing Grain Traceability Standards: CART and Simulation

February 18, 2020
Author(s)
Frank H. Riddick, Evan K. Wallace, Scott Nieman, Joe Tevis, R. A. Ferreyra
To ensure food safety, food manufacturers need the ability to quickly identify and trace food products to all equipment and processes throughout the entire associated food supply, production, and transportation network. Government and industry have

Quasi-two-dimensional magnon identification in antiferromagnetic FePS3 via magneto-Raman spectroscopy
