Susan S. Tai, Mary Bedner, Karen W. Phinney
… of 25(OH)D3-d3 and 25(OH)D2-d3 are used as internal standards for 25(OH)D3 and 25(OH) D2, respectively. The 25(OH)D3 and 25(OH)D2 along with their internal standards are simultaneously extracted from serum using …

ACSIM; Simulation Model of an Air Conditioner

February 2, 2026
Author(s)
Piotr Domanski
ACSIM is a simulation program for single-stage air conditioners consisting of a compressor, finned-tube evaporators and condensers, thermostatic and electronic expansion valves, and connecting tubing. For modeling heat exchangers, ACSIM uses evaporator and

Ferri, G. Gallucci
The determination of the absolute neutrino mass scale remains a fundamental open question in particle physics, with profound implications for both the standard model and cosmology. Direct kinematic measurements, independent of model-dependent assumptions,

Semantics for Enhancing Communications- and Edge-Intelligence-enabled Smart Sensors: A Practical Use Case in Federated Automotive Diagnostics

March 10, 2025
Author(s)
Eugene Song, Thomas Roth, David A. Wollman, Eoin Jordan, Martin Serrano, Amelie Gyrard
Modern edge artificial intelligence (AI) chipsets and edge-intelligence-enabled smart sensors frameworks support real-time data processing and event detection at the signal source. Beyond just measuring local conditions and transmitting corresponding

Compressed liquid density and speed of sound measurements and correlation of the binary mixture carbon dioxide (CO2) + 1,1-difluoroethene (R1132a)} at temperatures from 220 K to 350 K

January 22, 2025
Author(s)
Davide Menegazzo, Aaron Rowane, Giulia Lombardo, Sergio Bobbo, Laura Fedele, Mark McLinden
The combination of carbon dioxide (CO2) and R1132a has been proposed as a viable substitute for R23 in low-temperature applications. This study provides new experimental data on the compressed-liquid density, vapor density, and compressed-liquid speed of

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

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

Linking excess entropy and acentric factor in spherical fluids

September 9, 2024
Author(s)
Tae Jun Yoon, Ian Bell
Introduced by Kenneth Pitzer in 1955, the acentric factor (ω) became a standard quantity in chemical thermodynamics, representing a molecule's "shape" effect on the deviation from the corresponding state behavior. Nevertheless, its interpretation remains

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

Ratchet Loading and Multi-Ensemble Operation in an Optical Lattice Clock

August 8, 2024
Author(s)
Youssef Hassan, Takumi Kobayashi, Tobias Bothwell, Jacob Siegel, Benjamin Hunt, Kyle Beloy, Kurt Gibble, Tanner Grogan, Andrew Ludlow
We demonstrate programmable control over the spatial distribution of ultra-cold atoms confined in an optical lattice. The control is facilitated through a combination of spatial manipulation of the magneto-optical trap and atomic population shelving to a
