Systematic Review of Embodied Carbon Assessment and Reduction in Building Life Cycles

September 18, 2024
Author(s)
Yating Zhang, Siamak Sattar, Dustin Cook, Katherine Johnson, Juan Fung
The building and construction sector is the largest carbon emitter, accounting for more than one-third of annual global emissions. The emissions can be divided into operational and embodied carbon, associated with building operations and building materials

Assessing the Degree of Feature Interactions that Determine a Model Prediction

September 17, 2024
Author(s)
Krishna Khadka, Sunny Shree, Yu Lei, Raghu Kacker, David Kuhn
Machine Learning (ML) models rely on capturing important feature interactions to generate predictions. This study is focused on validating the hypothesis that model predictions often depend on interactions involving only a few features. This hypothesis is

In-process monitoring and non-destructive evaluation for metal additive manufacturing processes

September 17, 2024
Author(s)
Alkan Donmez, Jason Fox, Felix Kim, Brandon Lane, Maxwell Praniewicz, Vipin Tondare, Jordan Weaver, Paul Witherell
The rapid pace of maturation of metal additive manufacturing (AM) technologies, makes them an excellent candidate for the fabrication of nuclear power plant (NPP) components. However, the current levels of process variations create numerous challenges yet

On Combinatorial Security Testing for the Tor Anonymity Network Client

September 17, 2024
Author(s)
Dimitris Simos, Bernhard Garn, Dominik-Philip Schreiber, Manuel Leithner, David Kuhn, Raghu Kacker
In this paper, we present an application of combinatorial security testing to the well-known anonymity network Tor. Rigorous testing of the Tor network is important to evaluate not only its functionality, but also the security it provides to its users

Rydberg states of alkali atoms in atomic vapor as SI-traceable field probes and communications receivers

September 16, 2024
Author(s)
Noah Schlossberger, Samuel Berweger, Nikunjkumar Prajapati, Andrew Rotunno, Alexandra Artusio-Glimpse, Matthew Simons, Abrar Sheikh, Eric Norrgard, Stephen Eckel, Christopher Holloway
Rydberg states of alkali atoms are highly sensitive to electric fields because their electron wavefunction has a large spatial extent, leading to large polarizabilities for static fields and large transition dipole moments for time-varying fields. Over the

Model-Based Production Operational Control for Metal Additive Manufacturing

September 15, 2024
Author(s)
Duncan Gibbons, Paul Witherell
Metal additive manufacturing processes are influenced by many variables that affect the produced material to varying degrees. This wide range of variables and the complex fusion mechanisms inherent to these processes often result in a manufacturing process

Flexible superconducting wiring for integration with low temperature detector and readout fabrication

September 14, 2024
Author(s)
Galen O'Neil, Daniel Swetz, Joel Ullom, Daniel Schmidt, Joel Weber, John Mates, William Doriese, Mark Keller, Michael Vissers, Kelsey Morgan, Robinjeet Singh
We present a method of creating high density superconducting flexible wiring on flexible thin silicon substrates. The flexible wiring, called SOI flex, is created by depositing superconducting wiring on a silicon on insulator (SOI) wafer, selectively

Effect of Cosolvents on the Phase Separation of Polyelectrolyte Complexes

September 13, 2024
Author(s)
Yuanchi Ma, Robert Ivancic, Jan Obrzut, Debra Audus, Vivek Prabhu
Evidence is shown that cosolvent mixtures control the coacervation of mixtures of oppositely charged polyelectrolytes. Binary and ternary solvent mixtures lead to non-monotonic solubility as a function of measured average dielectric constants of the

Quadrature amplitude modulation for electronic side and Pound-Drever-Hall locking

September 13, 2024
Author(s)
Juntian Tu, Alessandro Restelli, Tsz-Chun Tsui, Kevin Weber, Ian Spielman, James(Trey) Porto, Steven Rolston, Sarthak Subhankar
The Pound-Drever-Hall (PDH) technique is routinely used to stabilize the frequency of a free-running laser to an ultralow expansion (ULE) reference cavity. The electronic sideband (ESB) locking scheme—a variant of the standard PDH locking scheme—helps

Building a Cybersecurity and Privacy Learning Program

September 12, 2024
Author(s)
Marian Merritt, SUSAN HANSCHE, BRENDA ELLIS, Julie Nethery Snyder, KEVIN SANCHEZ-CHERRY, DONALD WALDEN
This publication provides guidance for federal agencies and organizations to develop and manage a life cycle approach to building a Cybersecurity and Privacy Learning Program (CPLP). The approach is intended to address the needs of large and small

Plug-and-play protein biosensors using aptamer-regulated in vitro transcription

September 12, 2024
Author(s)
Heonjoon Lee, Tian Xie, Byunghwa Kang, Xinjie Yu, Samuel Schaffter, Rebecca Schulman
Molecular biosensors that accurately measure protein concentrations without external equipment are critical for solving numerous problems in diagnostics and therapeutics. Modularly transducing the binding of protein antibodies, protein switches or aptamers

A digital four-arm bridge for the comparison of resistance with capacitance

September 11, 2024
Author(s)
Yicheng Wang, Stephan Schlamminger
A digital four-arm bridge for the comparison of resistance with capacitance has been designed and demonstrated. The digital bridge mimics the classical quad bridge in the digital domain with three balances: the source balance, the detector balance, as well
