Spectroscopy of laser cooling transitions in MgF

August 23, 2024
Author(s)
Nickolas Pilgram, Benjamin Baldwin, David La Mantia, Stephen Eckel, Eric Norrgard
We measure the complete set of transition frequencies necessary to laser cool and trap MgF molecules. Specifically, we report the frequency of multiple low $J$ transitions of the $X^2\Sigma^+(v^\prime\prime}=0,1) \rightarrow A^2\Pi_1⁄2(v^\prime=0)$, $X^2

An Industrial Private 5G Testbed for Networked Automation Systems

August 22, 2024
Author(s)
Jing Geng, Mohamed Hany, Rick Candell
Interest in integrating wireless communication capabilities into industrial Cyber-Physical Systems (CPS) has surged recently. Driven by advantages like ease of deployment, reduced maintenance costs, and asset mobility, CPSs now employ wireless

Electromagnetically-Induced-Transparency Cooling with a Tripod Structure in a Hyperfine Trapped Ion with Mixed-Species Crystals

August 22, 2024
Author(s)
Jenny Wu, Pan-Yu Hou, Stephen Erickson, Adam Brandt, Yong Wan, Giorgio Zarantonello, Daniel Cole, Andrew C. Wilson, Daniel Slichter, Dietrich Leibfried
Cooling of atomic motion is a crucial tool for many branches of atomic physics, ranging from fundamental physics explorations to quantum information and sensing. For trapped ions, electromagnetically-induced-transparency (EIT) cooling has received

Latency-Sensitive Networked Control Using 802.11ax OFDMA Triggering

August 22, 2024
Author(s)
Karl Montgomery, Mohamed Hany, Rick Candell
Orthogonal Frequency-Division Multiple Access (OFDMA) is a feature implemented in IEEE 802.11ax (Wi-Fi 6) that aims to improve performance by sending packets simultaneously to multiple users. This paper highlights performance issues when using OFDMA with a

Towards Sustainable Electronics: Exploring IC Reuse for Circular Economy Transformation

August 22, 2024
Author(s)
Nowell Stoddard, Lisa Paterson, Mark Schaffer, Tom Etheridge, Nehika Mathur, KC Morris, Lise Laurin, Amos Ncube
This perspective paper addresses the importance of responsible end of life (EOL) management of integrated circuits (ICs or chips), with a particular focus on the possibility of IC reuse as an avenue to address the high impacts of chip manufacturing and the

Ultrastable vacuum-gap Fabry-Perot cavities 2 operated in air

August 21, 2024
Author(s)
Susan Schima, Franklyn Quinlan, Yifan Liu, Charles McLemore, Takuma Nakamura, Nazanin Hoghooghi, Scott Diddams, Peter Rakich, Dahyeon Lee, Naijun Jin, Megan Kelleher, Haotian Cheng
We demonstrate a vacuum-gap ultrastable optical reference cavity that does not require a vacuum enclosure. Our simple method of optical contact bonding in a vacuum environment allows for cavity operation in air while maintaining vacuum between the cavity

5G NR and LTE Downlink Coexistence Measurements Using Software-Defined Radios

August 20, 2024
Author(s)
Nadia Yoza Mitsuishi, Yao Ma, Jason Coder
With the rapid deployment of 5G New Radio (NR) in the sub-6 GHz frequency bands, cellular operators need to accommodate this new technology within the limited spectrum licensed to them, mostly occupied by 4G Long-Term Evolution (LTE). This poses the

Community Resilience Economic Decision Guide and Tool: Research Overview

August 20, 2024
Author(s)
Christina Gore, Jennifer Helgeson
Community resilience planning often requires quantifying and understanding the trade-offs that communities make between the benefits and costs of different resilience actions. The Economic Decision Guide walks communities through the steps to evaluate

Flow Activation Energy of High-Concentration Monoclonal Antibody Solutions and Protein-Protein Interactions Influenced by NaCl and Sucrose

Author(s)
Guangcui Yuan, Paul Salipante, Steven D. Hudson, Richard Gillilan, Qingqiu Huang, Harold Hatch, Vincent Shen, Alexander Grishaev, Suzette Pabit, Rahul Upadhya, Sudeep Adhikari, Jainik Panchal, Marco Blanco, Yun Liu
The solution viscosity and protein−protein interactions (PPIs) as a function of temperature (4−40 °C) were measured at a series of protein concentrations for a monoclonal antibody (mAb) with different formulation conditions, which include NaCl and sucrose

ProSAS: An O-RAN Approach to Spectrum Sharing between NR and LTE

August 20, 2024
Author(s)
Sneihil Gopal, David Griffith, Richard Rouil, Chunmei Liu
The Open Radio Access Network (O-RAN), an industry-driven initiative utilizes intelligent Radio Access Network (RAN) controllers and open interfaces to facilitate efficient spectrum sharing between LTE and NR RANs. In this paper, we harness O-RAN's

Model for the Viscosity and Thermal Conductivity of Tetrahydrofuran

August 17, 2024
Author(s)
Sofia Sotiriadou, Eleftheria Ntonti, Marc Assael, Konstantinos Antoniadis, Marcia L. Huber
We present a hybrid predictive-correlative engineering model for the calculation of the viscosity and thermal conductivity of tetrahydrofuran (THF) in the fluid phase. It incorporates critically evaluated experimental data where available, and predictive
