Low Energy Spiking Neural Network using Ge4Sb6Te7 Phase-Change Memory Synapses

August 6, 2024
Author(s)
Huairuo Zhang, Albert Davydov, Shafin Hamid, Eric Pop, Asir Khan
Spiking neural networks (SNN) with Ge2Sb2Te5 (GST) based phase change memory (PCM) synaptic devices are promising for edge applications. However, from a de-vice standpoint, the performance of such SNN is often con-strained by the abrupt depression

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

Measurement-Based Prediction of mmWave Channel Parameters Using Deep Learning and Point Cloud

August 2, 2024
Author(s)
Anuraag Bodi, Raied Caromi, Jian Wang, Jelena Senic, Camillo Gentile, Hang Mi, Bo Ai, Ruisi He
Millimeter-wave (MmWave) channel characteristics are quite different from sub-6 GHz frequency bands. The major differences include higher path loss and sparser multipath components (MPCs), resulting in more significant time-varying characteristics in

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

Additive Manufacturing of Highly Entangled Polymer Networks

August 1, 2024
Author(s)
Abhishek Dhand, Matthew Davidson, Hannah Zlotnick, Thomas Kolibaba, Jason Killgore, Jason Burdick
Incorporation of polymer chain entanglements within a single network can synergistically improve stiffness and toughness, yet attaining such dense entanglements through vat photopolymerization additive manufacturing (e.g., digital light processing, DLP)

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

AC Metrology Applications of the Josephson Effect

July 31, 2024
Author(s)
Samuel Benz
The performance of programmable voltage signals that exploit the quantum behavior of superconducting Josephson junctions continues to improve and enable new capabilities for applications in metrology, communications, and quantum control. We present the

Clock-line-mediated Sisyphus Cooling

July 31, 2024
Author(s)
Jacob Siegel, Benjamin Hunt, Tanner Grogan, Youssef Hassan, Kyle Beloy, Roger Brown, Andrew Ludlow, Chun-Chia Chen, Kurt Gibble
We demonstrate sub-recoil Sisyphus cooling using the long-lived 3P0 clock state in alkaline-earthlike ytterbium. A 1388 -nm optical standing wave nearly resonant with the 3P0→3D1 transition creates a spatially periodic light shift of the 3P0 clock state
