Coexistence Testing: Comparing Conducted and Radiated Test Results

August 9, 2024
Author(s)
Susanna Mosleh, Nadia Yoza Mitsuishi, Jason Coder, Carl Sunderman
In an era of ubiquitous wireless devices, ensuring their coexistence in shared electromagnetic environments has become increasingly critical. This paper explores the dynamics of coexistence testing and compares two coexistence test environments outlined in

A Review of Community Resilience Indicators Using a Systems Measurement Framework

August 5, 2024
Author(s)
Michael Gerst, Maria Dillard, Emily Walpole, Jarrod Loerzel
As natural disasters have increased in frequency and magnitude, there has been an increasing need to understand what underlying factors are likely to lead to faster recovery and more resilient communities. One way of addressing this need has been to

Contactless Fingerprint Capture and Data Interchange Best Practice Recommendation Revision 1

August 5, 2024
Author(s)
Shahram Orandi, Craig I. Watson, Jennifer Stathakis, John M. Libert, Gregory Fiumara, John Grantham
While contactless fingerprint capture devices stand to provide for many benefits, images from this nascent technology are sufficiently different than traditional contact-collected images thereby warranting the separation of these new contactless

The Proteomics Standards Initiative standardized formats for spectral libraries and fragment ion peak annotations: mzSpecLib and mzPAF

August 5, 2024
Author(s)
Joshua Klein, Henry Lam, Tytus Mak, Wout Bittremieux, Yasset Perez-Riverol, Ralf Gabriels, Jim Shofstahl, Helge Hecht, Pierre-Alain Binz, Shin Kawano, Tim Van Den Bossche, Jeremy Carver, Ben Neely, Luis Mendoza, Tomi Suomi, Tine Claeys, Thomas Payne, Douwe Schulte, Zhi Sun, Nils Hoffmann, Yunping Zhu, Steffen Neumann, Andrew Jones, Nuno Bandeira, Juan Antonio Vizcaino, Eric Deutsch
Mass spectral libraries are collections of reference spectra, usually associated with specific analytes from which the spectra were generated, that are used for further downstream analysis of new spectra. There are many different formats used for encoding

Optical n(p, T_90) measurement suite 3: results at l = 1542 nm

August 3, 2024
Author(s)
Patrick Egan, Yuanchao Yang
Single-isotherm n(p, T90) results are reported for the gases Ar, N2, H2O, and D2O at vacuum wavelength λ = 1542.383(1) nm. The argon and nitrogen isotherms were measured near 303 K; the water isotherms were measured near 373 K. Combined with the two

Metric Conversion Card

August 2, 2024
Author(s)
Elizabeth Benham, Kristen Dill
NIST SP 365, Metric Conversion Card is a laminated wallet size card includes an 8 cm and 80 mm ruler with approximate unit conversion factors between common International System of Units (SI) and U.S. customary measurement units for length, area, mass

Modeling Spiking Neurons without Spikes

August 2, 2024
Author(s)
Jeff Shainline, Bryce Primavera, Ryan O'Loughlin
While spiking neuromorphic hardware holds promise for efficient implementations of artificial intelligence, the impact has been limited due in part to a lack of learning algorithms that achieve performance superior to conventional deep learning. One

Construction of Highly Porous and Robust Hydrogen-Bonded Organic Framework for High-Capacity Clean Energy Gas Storage

August 1, 2024
Author(s)
Jia-Xin Wang, Xu Zhang, Changhao Jiang, Teng-Fei Zhang, Jiyan Pei, Wei Zhou, Taner N. Yildirim, Banglin Chen, Guodong Qian, Bin Li
Development of highly porous and robust hydrogen bonded organic frameworks (HOFs) for high-pressure methane and hydrogen storage remains a grand challenge due to the fragile nature of hydrogen bonds. Herein, we report a strategy of constructing the double

Quantum state tracking and control of a single molecular ion in a thermal environment

August 1, 2024
Author(s)
Yu Liu, Julian Schmidt, Zhimin Liu, David Leibrandt, Dietrich Leibfried, Chin-wen Chou
Understanding molecular state evolution is central to many disciplines, including molecular dynamics, precision measurement, and molecule-based quantum technology. Details of this evolution are obscured when observing a statistical ensemble of molecules

Orthogonal Determination of Competing Surfactant Adsorption onto Single-Wall Carbon Nanotubes During Aqueous Two-Polymer Phase Extraction via Fluorescence Spectroscopy and Analytical Ultracentrifugation

July 31, 2024
Author(s)
Christopher Sims, Jeffrey Fagan
A combination of analytical ultracentrifugation (AUC) and fluorescence spectroscopy are utilized to orthogonally probe compositions of adsorbed surfactant layers on the surface of (7,5) species single-wall carbon nanotubes (SWCNTs) under conditions known

Characterizing the Broadband RF Permittivity of 3D-Integrated Layers in a Glass Wafer Stack from 100 MHz to 30 GHz

July 30, 2024
Author(s)
Jacob Pawlik, Tomasz Karpisz, Nicholas Derimow, Sarah Evans, Jim Booth, Nate Orloff, Chris Long, Angela Stelson
We present a method for accurately determining the permittivity of dielectric materials in 3D integrated structures at broadband RF frequencies. With applications of microwave and millimeter-wave electronics on the rise, reliable methods for measuring the
