Finding Kinship in the Women in Radio Science (WIRS) Chapter

August 17, 2022
Author(s)
Reyhan Baktur, zoya popovic, Jeanne Quimby, Emily Porter
This paper introduces the Women in Radio Science, the newest Chapter of the US National Committee of the International Union of Radio Science. The unique challenges of minority groups in radio science community are discussed. Value and impact of

Recommendation for Key Derivation Using Pseudorandom Functions

August 17, 2022
Author(s)
Lily Chen
This Recommendation specifies techniques for the derivation of additional keying material from a secret key—either established through a key-establishment scheme or shared through some other manner—using pseudorandom functions: HMAC, CMAC, and KMAC.

Relative effects of polymer composition and sample preparation on glass dynamics

August 17, 2022
Author(s)
Christopher Soles, Amanda L. Forster, Katherine Evans, Madhusudan (Madhu) Tyagi, Robert M. Elder, Timothy Sirk, Joseph Dennis, Kanae Ito, Osama Yamamuro, Hiroshi Akiba
Modern design of common adhesives, composites and polymeric parts makes use of polymer glasses that are stiff enough to maintain their shape under a high stress while still maintaining a ductile behavior after the yield point. Typically, material

The Single Residue K12 Governs the Exceptional Voltage Sensitivity of Mitochondrial Voltage-Dependent Anion Channel Gating

August 17, 2022
Author(s)
Van Ngo, Maria Queralt-Martin, Farha Khan, Lucie Bergdoll, Jeff Abramson, Sergey M. Bezrukov, Tatiana Rostovtseva, David Hoogerheide, Sergei Noskov
The voltage-dependent anion channel (VDAC) is a β-barrel channel of the mitochondrial outer membrane (MOM) that passively transports ions, metabolites, polypeptides, and single-stranded DNA. VDAC responds to a transmembrane potential by transitioning to a

Report on the DHS/NIST Workshop on Standards for an Enduring Capability in Wastewater Surveillance for Public Health (SWWS Workshop)

August 16, 2022
Author(s)
Nancy Lin, Stephanie Servetas, Scott Jackson, Katrice Lippa, Kirsten Parratt, Philip Mattson, Clare Beahn, Mia Mattioli, Sally Gutierrez, Michael Focazio, Ted Smith, Paul Storella, Sarah Wright
Wastewater surveillance is a promising approach to monitor biological and chemical contaminants on a community level in support of public health and safety decisions. Wastewater surveillance has recently been shown highly effective for the early detection

30 GHz regenerative frequency divide-by-3

August 15, 2022
Author(s)
Archita Hati, Marco Pomponio, Connor Humiston, John Lettang, Craig Nelson
We report the performance of a 30 GHz to 10 GHz regenerative frequency divider. The proposed divider design incorporates the conventional Miller regenerative frequency divider (divide-by-2) with an additional regenerative path. We achieve output referred

Atomically Dispersed CuNx Sites from Thermal Activation of Boron Imidazolate Cages for Electrocatalytic Methane Generation

August 12, 2022
Author(s)
Soumyodip Banerjee, Justin Gorham, Maxime Siegler, Natalia Drichko, Joshua Wright, Nicholas Bedford, Sara Thoi
Atomically dispersed heteroatom coordinated metal sites (ADMS) have been recognized as promising candidates for electrochemical conversion. Among a diverse range of molecular precursors for ADMS synthesis, framework materials are particularly interesting

PION: Password-based IoT Onboarding Over Named Data Networking

August 11, 2022
Author(s)
Davide Pesavento, Junxiao Shi, Kerry McKay, Lotfi Benmohamed
While the IoT market continues to grow, securing IoT systems remains a challenge as successful cyberattacks keep escalating. Named Data Networking (NDN) offers a number of advantages over traditional IP-based communications and is considered a promising

Towards an Integrated Simulation Platform for Internet of Vehicles

August 11, 2022
Author(s)
Xing Liu, Wei Yu, Cheng Qian, David W. Griffith, Nada T. Golmie
The interconnection and digitization of the physical world has increased dramatically with the widespread deployment of network communication and the rapid development of the Internet of Things (IoT). Application scenarios and requirements in IoT are more

Complete collision data set for electrons scattering on molecular hydrogen and its isotopologues: III. Vibrational excitation via electronic excitation and radiative decay.

August 10, 2022
Author(s)
Dmitry Fursa, Mark Zammit, Igor Bray, Liam Scarlett, Daniel Boyle, Yuri Ralchenko
We present cross sections for vibrational excitation via electronic excitation followed by radiative decay (ERD), for electrons scattering on all bound vibrational levels of the ground electronic state (X 1Σ+ g ) of molecular hydrogen and its isotopologues

Towards Understanding the Magnetic Properties of the Breathing Pyrochlore Compound Ba 3 Yb 2 Zn 5 O 11 through Single-Crystal Studies

August 10, 2022
Author(s)
Sachith Dissanayake, Zhenzhong Shi, Jeffrey Rau, Rabindranath Bag, William Steinhardt, Nicholas Butch, Matthias Frontzek, Andrey Podlesnyak, David Graf, Casey Marjerrison, Jue Liu, Michel J. Gingras, Sara Haravifard
Ba 3Yb 2Zn 5O 11 is unique among breathing pyrochlore compounds for being in the nearly-decoupled limit where inter-tetrahedra interactions are weak, hosting isolated clusters or molecular magnet like tetrahedra of magnetic ytterbium (Ybu3+^) ions. In this

Wind-Driven Fire Spread to a Structure from Fences and Mulch

August 10, 2022
Author(s)
Kathryn Butler, Erik L. Johnsson, Alexander Maranghides, Shonali Nazare, Marco G. Fernandez, Rachel McIntyre, William Saar, Mariusz Zarzecki, Wei Tang, Eric Auth, Michael Pryor, Colin McLaughlin
A series of field experiments was conducted to examine the effects on fire spread toward a structure for combustible fences and mulch under conditions that may be encountered in a wildland-urban interface (WUI) fire. The fire behavior of a variety of

A constant pressure flowmeter for the extremely high vacuum

August 9, 2022
Author(s)
Stephen Eckel, Daniel Barker, James A. Fedchak, Emmanuel Newsome, Julia Scherschligt, Robert E. Vest
We demonstrate operation of a constant-pressure flowmeter capable of generating and accurately measuring flows as low as $1\times10^-13}$mol/s. Generation of such small flows is accomplished by using a small conductance element with $C\approx 25$nL/s
