Voices of First Responders - Examining Public Safety Communication from the Perspective of 9-1-1 Call Takers and Dispatchers: Findings from User-Centered Interviews, Phase 1, Volume 4

March 24, 2020
Author(s)
Michelle P. Steves, Mary Theofanos, Yee-Yin Choong, Shanee Dawkins, Susanne M. Furman, Kristen K. Greene, Sandra Spickard Prettyman
With the newly created Nationwide Public Safety Broadband Network (NPSBN), the public safety community has a unique opportunity to review and improve communication technology for first responders, 9 1 1 communications, emergency medical services (EMS)

Automatic Volumetric Segmentation of Additive Manufacturing Defects with 3D U-Net

March 23, 2020
Author(s)
Vivian W. Wong, Max Ferguson, Kincho Law, Yung-Tsun Lee, Paul Witherell
Segmentation of defects in additive manufacturing is challenging, due to the poor contrast, small sizes and variation in appearance of defects. Automatic segmentation can however provide quality control for additive manufacturing. Over recent years, 3D

Chemically Orthogonal Hole Transport Layer for Efficient Colloidal Quantum Dot Solar Cells

March 20, 2020
Author(s)
Margherita Biondi, Min-Jae Choi, Olivier Ouellette, Se-Woong Baek, Petar Todorovi?, Bin Sun, Peicheng Li, Ahmad R. Kirmani, Laxmi Chiluka, Lee J. Richter, Sjoerd Hoogland, Zheng-Hong Lu, F. Pelayo Garc?a de Arquer, Edward H. Sargent, Mingyang Wei
Colloidal quantum dots (CQDs) are of interest in light of their solution-processing and bandgap tuning. Advances in the performance of CQD optoelectronic devices require fine control over the properties of each layer in the device materials stack. This is

NIST Time and Frequency Bulletin

Author(s)
Kelsey A. Rodriguez
The Time and Frequency Bulletin provides information on performance of time scales and a variety of broadcasts (and related information) to users of the NIST services.

Tuning between photon-number and quadrature measurements with weak-field homodyne detection

March 20, 2020
Author(s)
G Thekkadath, David Phillips, Jacob Bulmer, W.R. Clements, A. Eckstein, B.A. Bell, J Lugani, Adriana Lita, Sae Woo Nam, Thomas Gerrits, C.G. Wade, Ian Walmsley
Variable measurement operators enable optimization of strategies for testing quantum properties and for preparation of a range of quantum states. Here, we experimentally implement a weak-field homodyne detector that can continuously tune between performing

Voices of First RespondersNationwide Public Safety Communication Survey Methodology: Development, Dissemination, and Demographics, Phase 2, Volume 1

March 20, 2020
Author(s)
Kristen Greene, Shanee T. Dawkins, Sandra S. Prettyman, Pamela J. Konkol, Mary F. Theofanos, Kevin C. Mangold, Susanne M. Furman, Michelle P. Steves
With the newly created Nationwide Public Safety Broadband Network (NPSBN), the public safety community is in the process of supplementing the use of land mobile radios (LMR) to a technology ecosystem that will include a variety of new communication tools

Doping of MoTe2 via surface charge-transfer in ambient air

March 19, 2020
Author(s)
Gheorghe Stan, Cristian Ciobanu, Sri Ranga Jai Likith, Asha Rani, Sergiy Krylyuk, Albert Davydov
Doping is a key process that facilitates the use of semiconductors for electronic and optoelectronic devices, by which the concentration and type of majority carriers (electrons or holes) can be modified controllably to achieve desired conduction

Effect of Elevated Temperature and Humidity on Fibers Based on 5-amino-2-(p-aminophenyl) benzimidazole (PBIA)

March 19, 2020
Author(s)
Amy E. Engelbrecht-Wiggans, Ajay Krishnamurthy, Lucas H. Kaplan, Amanda L. Forster, Thanh N. Hoang, Viviana Bentley
Traditionally, soft body armor has been made from materials such as poly(p-phenylene terephthalamide) (PPTA) and ultra-high molar mass polyethylene (UHMMPE). However, to diversify the fiber choices in the United States body armor market, copolymer fibers

Reduced-Order Modeling of Composite Floor Slabs in Fire. I: Heat-Transfer Analysis

March 18, 2020
Author(s)
Jian Jiang, Joseph Main, Jonathan Weigand, Fahim H. Sadek
This paper presents a reduced-order numerical modeling approach for the analysis of heat transfer in composite floor slabs with profiled steel decking exposed to fire effects. This approach represents the thick and thin portions of a composite slab with
