EVALUATING IDENTITY LEAKAGE IN SPEAKER DE-IDENTIFICATION SYSTEMS

August 21, 2025
Author(s)
Seungmin Seo, Oleg Aulov, Afzal Godil, Kevin Mangold
Speaker de-identification aims to conceal a speaker's identity while preserving intelligibility of the underlying speech. We introduce a benchmark that quantifies residual identity leak- age with three complementary error rates: equal error rate (EER)

Evaluating the Impact of Changes to the Internal Publication Review Policy at NIST

August 21, 2025
Author(s)
Juan Fung, Michael Hall, Jennifer Helgeson, Alden Dima, Anne Andrews, Jennifer Benkstein
This report presents the design and methodology of a survey conducted to evaluate the impact of changes to the organizational publication review policy at the National Institute for Standards and Technology (NIST). The purpose of the survey is to collect

Kelvin probe force microscopy under ambient conditions

August 21, 2025
Author(s)
Amirhossein Zahmatkeshsaredorahi, Ruben Millan-Solsona, Devon Jakob, Liam Collins, Xiaoji Xu
Kelvin Probe Force Microscopy (KPFM), a technique derived from Atomic Force Microscopy (AFM), provides nanometer-scale spatial resolution for mapping surface potential or work function differences across material systems. It serves as a powerful tool for

Considerations for Implementing Morph Detection in Operations

August 18, 2025
Author(s)
Mei Ngan, Patrick Grother
Morphing of face photographs present a threat to identity processes; for example, two people being able to use one passport. The threat exists in applications that allow users to submit their own photos where digital history is unknown. The threat can be

Quantum Vibro-Polaritonic Sensing

August 15, 2025
Author(s)
Peng Zheng, Stephen Semancik, Ishan Barman
Vibrational spectroscopies are pivotal in analytical methods and biomedical diagnostics owing to their singular ability to provide molecular specificity. Yet, they are intrinsically limited by weak light-matter interactions and their vulnerability to

System-Level Calibration of a Millimeter-Wave Vector Signal Analyzer with Uncertainties

August 15, 2025
Author(s)
Joshua Kast, Paritosh Manurkar, Catherine Remley, Dylan Williams, Robert Horansky
We describe the system-level calibration of a vector signal analyzer operating in the 28 GHz frequency band, including the determination of uncertainties in the magnitude and phase of measurements of a traceably characterized calibration waveform. We then

Interfacial Alloying Contributions to the Magnetic Proximity Effect in Pt/Dysprosium Iron Garnet

August 12, 2025
Author(s)
Miela J. Gross, Javier Herrero-Martin, Sergio Valencia, Alexander Grutter, Julie Borchers, Yongseong Choi, Gilberto Fabbris, Allison Kaczmarek, Alexander E. Kossak, Jackson Bauer, Subhajit Kundu, Supriya Ghosh, K. A. Mkhoyan, Angela Wittmann, Caroline A. Ross
The magnetic proximity effect (MPE) plays an important role in the behavior of heavy-metal (HM)/ferro- or ferrimagnet thin film heterostructures, but for HM/rare earth iron garnet interfaces the presence and magnitude of the MPE has been debated. We

Fully transparent GaN/InGaN LED as a position sensitive detector

August 11, 2025
Author(s)
Christine McGinn, Keith Behrman, Emily Bittle, Pragya Shrestha, Qingyuan Zeng, Vikrant Kumar, Christina Hacker, Ioannis Kymissis
Commercial imaging technologies have an increasing need for an accurate, in-situ beam locator to ensure laser alignment during operation. In this work, gallium nitride LED with indium gallium nitride quantum wells is leveraged is leveraged to create a

Characterizing Cell-Free Transcription and Translation Dynamics with Nucleic Acid-Based Assays

August 10, 2025
Author(s)
Fernanda Piorino Macruz de Oliveira, Chad Alan Sundberg, Elizabeth Strychalski, Eugenia Romantseva
Characterization of cell-free expression (CFE) systems must expand beyond single spectrophotometric measurements of a green fluorescent protein to provide meaningful metrics of system performance over the course of a CFE reaction and enable the development

August 8, 2025
Author(s)
J. Terragni, I.E. Gordon, Erin Adkins, C. Boulet, A. Campargue, D. Chistikov, A. Finenko, H. Finkenzeller, H. Fleurbaey, R. J. Hargreaves, R.K. Hanson, J.-M. Hartmann, A. Klingberg, E. Kohler, A. O. Koroleva, D. Mondelain, G. Piccioni, S. Stefani, C. L. Strand, H. Tran, M. Turbet, A. Vigasin, F. Vitali, R. Volkamer, C. Wei
Collision-Induced Absorption (CIA) phenomena play a key role in the atmospheric energy balance, making their accurate parametrization a decisive factor in modeling planetary atmospheres. This is the primary reason why the HITRAN spectroscopic database

Radio Frequency from Optical with Instabilities below 10^-15 - Generation and Measurement

August 8, 2025
Author(s)
Archita Hati, Marco Pomponio, Nicholas Nardelli, Tanner Grogan, Kyungtae Kim, Dahyeon Lee, Jun Ye, Tara Fortier, Andrew Ludlow, Craig Nelson
This paper presents a frequency synthesis that achieved exceptional stability by transferring optical signals to the RF domain at 100 MHz. These systems employ a cryogenic silicon cavity-stabilized laser at 1542 nm and an ultra-low expansion (ULE) glass

August 8, 2025
Author(s)
Erin Adkins, Joseph Hodges
Light-matter interactions involving molecular oxygen (O2) span numerous decades in the frequency of electromagnetic radiation and are important tomany thermophysical and thermochemical mechanisms, ranging from atmospheric remote sensing of greenhouse gases

Three-dimensional nucleation and growth of deformation twins in magnesium
