Algorithm-Supervised Millimeter Wave Indoor Localization using Tiny Neural Networks

January 17, 2025
Author(s)
Anish Shastri, Steve Blandino, Camillo Gentile, Chiehping Lai, Paolo Casari
The quasi-optical propagation of mmw signals has been instrumental in designing high-accuracy localization algorithms. These algorithms either exploit the geometric properties of the mmw signals or are based on an environment's radio footprints, leading to

Additive Construction - The Path to Standardization II: Workshop Report

January 16, 2025
Author(s)
Shawn Platt
The "Additive Construction – The Path to Standardization II" workshop, hosted by the National Institute of Standards and Technology (NIST) and U.S. Army Engineer Research and Development Center (ERDC), brought together key players from the additive

A Helmholtz Energy Equation of State for 3,3,3-Trifluoroprop-1-ene (R-1243zf)

January 15, 2025
Author(s)
Ryo Akasaka, Eric Lemmon
A new fundamental equation of state expressed as a function of the Helmholtz energy is presented for 3,3,3-trifluoroprop-1-ene (R-1243zf). The equation is valid from the triple point temperature (122.35 K) to 430 K at pressures up to 35 MPa. The expected

Towards Precision Spectroscopy of Antiprotonic Atoms for Probing Strong-field QED

January 15, 2025
Author(s)
Goncalo Baptista, Shikha Rathi, Michael Roosa, Quentin Senetaire, Jonas Sommerfeldt, Toshiyuki Azuma, Daniel Becker, Francois Butin, Ofir Eizenberg, Joseph Fowler, Hiroyuki Fujioka, Davide Gamba, Nabil Garroum, Mauro Guerra, Tadashi Hashimoto, Takashi Higuchi, Paul Indelicato, Jorge Machado, Kelsey Morgan, Francois Nez, Jason Nobles, Ben Ohayon, Shinji Okada, Daniel Schmidt, Daniel Swetz, Joel Ullom, Pauline Yzombard, Marco Zito, Nancy Paul
PAX (antiProtonic Atom X-ray spectroscopy) is a new experiment with the aim to test strong-field quantum electrodynamics (QED) effects by performing high-precision x-ray spectroscopy of antiprotonic atoms. By utilizing advanced microcalorimeter detection

Automation of Quantum Dot Measurement Analysis via Explainable Machine Learning

January 13, 2025
Author(s)
Daniel Schug, Tyler Kovach, Michael Wolfe, Jared Benson, Sanghyeok Park, J. P. Dodson, Joelle Corrigan, Mark Eriksson, Justyna Zwolak
The rapid development of quantum dot (QD) devices for quantum computing has necessitated more efficient and automated methods for device characterization and tuning. Many of the measurements acquired during the tuning process come in the form of images

Polynomial-Time Classical Simulation of Noisy IQP Circuits after Constant Depth

January 12, 2025
Author(s)
Joel Rajakumar, James Watson, Yi-Kai Liu
Sampling from the output distributions of quantum computations comprising only commuting gates, known as instantaneous quantum polynomial (IQP) computations, is believed to be intractable for classical computers, and hence this task has become a leading

Expanded quasi-static models to predict the performance of robotic skins on soft cylinders

January 11, 2025
Author(s)
Jennifer Case, Gabrielle Branin, Ellen Yang, Stephanie Woodman, Rebecca Kramer-Bottiglio, James Gibert
Robotic skins are planar substrates with embedded sensors and actuators that are designed to wrap around soft, passive objects to enable multiple functionalities, such as locomotion and manipulation. We previously introduced a control model that relied on

Juana Williams, John McGuire, Loren Minnich, Gloria Lee, Jan Konijnenburg, Isabel Baucom, Katrice Lippa
The NIST Office of Weights and Measures (OWM) presents its second issue of the 2024 NIST Annual Summary of U.S. Legal Metrology Activities report. This report includes a summary of changes made to NIST Handbook 44 (2024) Specifications, Tolerances and

Checking the Net Contents of Packaged Goods

January 10, 2025
Author(s)
John McGuire, David Sefcik, Loren Minnich, Isabel Baucom, Katrice Lippa
This handbook has been prepared as a procedural guide for the compliance testing of net content statements on packaged goods. Compliance testing of packaged goods is the determination of the conformance results of packaging, distribution, and sale of

Commutability Assessment of New Standard Reference Materials (SRMs) for Determining Serum Total 25-Hydroxyvitamin D using Ligand Binding and Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS) Assays

January 10, 2025

Stephen Wise, Etienne Cavalier, Pierre LUKAS, Stephanie Peeters, caroline Le Goff, Laura Briggs, Emma Williams, Ekaterina Mineva, Christine Pfeiffer, Hubert Vesper, Christian Popp, Christian Beckert, Jan Schultess, Kevin Wang, Carole Tourneur, Camille Pease, Dominik Osterritter, Ralf Fischer, Ben Saida, Chao Dou, Satoshi Kojima, Hope Weiler, Agnieszka Bielecki, Heather Pham, Alexandra Bennett, Shawn You, Amit Ghoshal, Chistian Vogl, James Freeman, Neil Parker, Samantha Pagliaro, Jennifer Cheek, Jie Li, Hisao Tsukamoto, Karen Galvin, Kevin Cashman, Hsuan-Chieh Liao, Andrew Norbert Hoofnagle, Jeffery Budd, Adam Kuszak, Ashley Boggs-Russell, Carolyn Burdette, Grace Hahm, Federica Nalin, Johanna Camara
Commutability is where the measurement response for a reference material (RM) is the same as for an individual patient sample with the same concentration of analyte measured using two or more measurement systems. Assessment of commutability is essential

Fault-tolerant quantum memory using low-depth random circuit codes

January 10, 2025
Author(s)
Jon Nelson, Gregory Bentsen, Steven Flammia, Michael Gullans
Low-depth random circuit codes possess many desirable properties for quantum error correction but have so far only been analyzed in the code capacity setting where it is assumed that encoding gates and syndrome measurements are noiseless. In this work, we
