Reference Correlation for the Thermal Conductivity of Ethane-1,2-diol (Ethylene Glycol) from the Triple Point to 475 K and Pressures up to 100 MPa

September 14, 2021
Author(s)
Marko Mebelli, Danai Velliadou, Marc Assael, Konstantinos D. Antoniadis, Marcia L. Huber
We present a new wide-ranging correlation for the thermal of ethane-1,2-diol (ethylene glycol) based on critically evaluated experimental data. The correlation is designed to be used with an existing equation of state, and it is valid from the triple point

Single-photon detection in the mid-infrared up to 10 micron wavelength using tungsten silicide superconducting nanowire detectors

Varun Verma, Adriana Lita, Yao Zhai, Heli C. Vora, Richard Mirin, Sae Woo Nam, Boris Korzh, Alex Walter, Ryan Briggs, Marco Colangelo, Emma Wollman, Andrew Beyer, Jason Allmaras, D. Zhu, Ekkehart Schmidt, A. G. Kozorezov, Matthew Shaw
We developed superconducting nanowire single-photon detectors (SNSPDs) based on tungsten silicide (WSi) that show saturated internal detection efficiency up to a wavelength of 10 um. These detectors are promising for applications in the mid-infrared

A Bilateral Comparison of NIST And PTB Laser Power Standards for Scale Realization Confidence by Gravitational Wave Observatories

September 13, 2021
Author(s)
Matthew Spidell, John Lehman, Stefan Kueck, Marco Lopez, Holger Lecher, Richard Savage, Dripta Bhattacharjee
The Gravitational Wave (GW) observatories calibrate interferometer displacement using photon momentum, with laser power serving as the measurand. These observatories are traceable to the International System of Units through a primary standard maintained

High Aspect Ratio Ag Nanowire Mat Electrodes for Electrochemical CO production from CO2

September 13, 2021
Author(s)
David Raciti, Trevor Braun, Brian M. Tackett, Heng Xu, Mutya Cruz, Benjamin Wiley, Thomas Moffat
An interconnected network of high-aspect ratio Ag nanowires was pressed against porous gas diffusion layers (both conductive or non-conductive) to use as a gas diffusion electrode (GDE) for the electrochemical reduction of CO2 to CO. Varying the amount of

Towards Absolute Viability Measurements for Bacteria

September 12, 2021
Author(s)
Joy Dunkers, Hariharan K. Iyer, Brynna H. Jones, Charles Camp, Stephan J. Stranick, Nancy Lin
Quantifying viable, vegetative bacteria is a critical measurand in healthcare diagnostics, food safety, and antimicrobial development. Viability determination has traditionally relied on such techniques as plate counting, colorimetric or fluorescent

Pendellosung Interferometry Probes the Neutron Charge Radius, Lattice Dynamics, and Fifth Forces

September 10, 2021

Benjamin J. Heacock, Robert W. Haun, Michael G. Huber, Albert Henins, Robert C. Valdillez, Takuhiro Fujiie, Katsuya Hirota, Masaaki Kitaguchi, Hirohiko Shimizu, Takuya Hosobata, Masahiro Takeda, Yutaka Yamagata
Structure factors describe how incident radiation is scattered from materials such as silicon and germanium and characterize the physical interaction between the material and scattered particles. We used neutron Pendellösung interferometry to make

Tools, Models and Dataset for IEEE 802.11ay CSI-based Sensing

September 10, 2021
Author(s)
Steve Blandino, Tanguy Ropitault, Anirudha Sahoo, Nada T. Golmie
The ubiquitous deployment and availability of wireless communication devices create the perfect opportunity to provide new wireless local area network (WLAN) use-cases, by implementing new sensing capabilities, while leveraging existing communications

A Framework for the Composition of IoT and CPS Capabilities

September 9, 2021
Author(s)
Khalid Halba, Edward Griffor, ANTON DAHBURA, ahmed lbath
By 2030, over half-trillion devices will be connected to the internet. With so many devices with a wide range of capabilities, there is a need for a framework for innovation and reuse of IoT and CPS capabilities. Such framework should facilitate

Classifying Memory Bugs Using Bugs Framework Approach

September 9, 2021
Author(s)
Irena Bojanova, Carlos Galhardo
In this work, we present an orthogonal classification of memory corruption bugs, allowing precise structured descriptions of related software vulnerabilities. The Common Weakness Enumeration (CWE) is a well-known and used list of software weaknesses

Critical considerations for the design of multi-organ microphysiological systems (MPS)

September 9, 2021
Author(s)
Mridu Malik, Yang Yang, Parinaz Fathi, Gretchen Mahler, Mandy Esch
The process of identifying new drugs and getting them approved for use in patients requires extensive preclinical studies and clinical trials. Preclinical studies rely on in vitro experiments and animal models of human diseases. The reliability of data

Low barrier height in a ZnO nanorods/NbSe2 heterostructure prepared by van der Waals epitaxy

September 9, 2021
Author(s)
Yeonhoo Kim, Roxanne Tutchton, Ren Liu, Sergiy Krylyuk, Jian-Xin Zhu, Albert Davydov, Young Joon Hong, Jinkyoung Yoo
Two-dimensional (2D) materials as contacts for semiconductor devices have attracted great attention due to minimizing Fermi level pinning. Schottky–Mott physics has been widely employed to design 2D material-based electrodes and to elucidate their contact

Modeling MCPTT and User Behavior in ns-3

September 9, 2021
Author(s)
Wesley Garey, Thomas Henderson, Yishen Sun, Richard A. Rouil, Samantha Gamboa Quintiliani
To support the advancement of public safety communications technology, the Third Generation Partnership Project (3GPP) has created several standards to define Mission Critical Push-To-Talk (MCPTT) over Long Term Evolution (LTE) networks. As this is a new

PyLCP: A python package for computing laser cooling physics

September 9, 2021

Stephen Eckel, Daniel Barker, Eric Norrgard, Julia Scherschligt
We present a python object-oriented computer program for simulating various aspects of laser cooling physics. Our software is designed to be both easy to use and adaptable, allowing the user to specify the level structure, magnetic field profile, or the

Response Time Impact of Smoke Alarms

September 9, 2021
Author(s)
Stanley W. Gilbert, Thomas Cleary, Paul A. Reneke, Richard Peacock, David Butry
It can be assumed that smoke alarms reduce reported fires and casualties by reducing on average the amount of time it takes to detect a fire. This paper sets out to determine by how much that detection time is reduced. It does so by comparing the effect of
