Behavior and Limit States of Long-Span Composite Floor Beams with Simple Shear Connections subject to Compartment Fires: Experimental Evaluation

March 24, 2020
Author(s)
Lisa Y. Choe, Selvarajah Ramesh, William L. Grosshandler, Matthew S. Hoehler, Mina S. Seif, John L. Gross, Matthew F. Bundy
This paper presents the results of compartment fire experiments on four 12.8 m long composite floor beams with various end support conditions. Specimens were constructed as partially- composite beams, consisting of W18x35 steel beams and 83 mm thick

Chiral Superconductivity in Heavy-Fermion Metal UTe 2

March 24, 2020
Author(s)
Lin Jiao, Sean Howard
Spin-triplet superconductivity is a condensate of electron pairs with spin-1 and an odd parity pair wavefunction 1. A particularly interesting manifestation of triplet pairing is a chiral p-wave state which is topologically non-trivial and a natural

Strategic Roadmap for Interoperable Public Safety Analytics

March 24, 2020
Author(s)
Diane E. Ridgeway
Since 9/11, the Department of Homeland Security has provided over $16 billion dollars in grant assistance to secure cities and non-profit organizations against terrorist and disaster incidents. In order to meet the threat demands, public safety

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

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
