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

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

Quantifying High Density Polyethylene Flows in the United States using Material Flow Analysis

August 20, 2024
Author(s)
Abheek Chatterjee, Nehika Mathur, Daniel Figola, Matthew Triebe, Buddhika Hapuwatte, Ashley Hartwell, Katherine Morris
A Circular Economy (CE) aims to reduce natural resource consumption, waste generation, and related detrimental environmental, social, and economic impacts by retaining valuable materials in the economy as long as possible. This research focuses on the

A Standards-Guided Approach for Formalizing Product Circularity Assessment Metrics

August 19, 2024
Author(s)
Junwon Ko, Sandwana Sneethan, Gisele Bortolaz Guedes, Fazleena Badurdeen, I.S. Jawahir, Buddhika Hapuwatte, KC Morris
The industrial transition towards a more sustainable Circular Economy (CE) emphasizes the need for products that align with CE principles and robust methods for assessing their circularity performance. However, ambiguities between metrics vs. indicators

Quantum Sensing with Erasure Qubits

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

Bilayer crystals of trapped ions for quantum information processing

August 16, 2024
Author(s)
Samarth Hawalder, Prakriti Shahi, Allison Carter, Ana Rey Ayala, John J. Bollinger, Athreya Shankar
Trapped ion systems are a leading platform for quantum information processing, but they are currently limited to 1D and 2D arrays, which imposes restrictions on both their scalability and their range of applications. Here, we propose a path to overcome

Structure Development in Cross-Linked, Soybean Oil-based Waterborne Polyurethanes

August 16, 2024
Author(s)
Zoran S Petrovic, Jasna Djonlagic, Jian Hong, Milica Vukovic, Jan Ilavsky, Brian Bush, Fan Zhang
Development of waterborne polyurethanes (WPU) using bio-based sources represents a step towards sustainable materials science and industry. We synthesized bio-based cationic water-dispersed crosslinked polyurethanes from high oleic soybean oil (HOSO)
