Adversarial Machine Learning: A Taxonomy and Terminology of Attacks and Mitigations

March 24, 2025
Author(s)
Apostol Vassilev, Alina Oprea, Alie Fordyce, Hyrum Anderson, Xander Davies, Maia Hamin
This NIST Trustworthy and Responsible AI report provides a taxonomy of concepts and defines terminology in the field of adversarial machine learning (AML). The taxonomy is arranged in a conceptual hierarchy that includes key types of ML methods, life cycle

A method to calibrate angular positioning errors using a laser tracker and a plane mirror

March 20, 2025
Author(s)
Balasubramanian Muralikrishnan, Katharine Shilling, Vincent Lee, Olga Ridzel, Glenn Holland, John Villarrubia
We describe a method to calibrate angular positioning errors of a rotation stage using a laser tracker (LT), a plane mirror mounted on the stage, and stationary registration nests placed around the stage. Our technique involves determining the direction of

Electron transport in bilayer graphene nanoconstrictions patterned using atomic force microscope nanolithography

March 20, 2025
Author(s)
Robert Rienstra, Nishat Sultana, En-Min Shih, Evan Stocker, Kenji Watanabe, Takashi Taniguchi, Curt Richter, Joseph Stroscio, Nikolai Zhitenev, Fereshte Ghahari Kermani
Here we report on low temperature transport measurements of encapsulated bilayer graphene nano constrictions fabricated employing electrode-free AFM-based local anodic oxidation (LAO) nanolithography. This technique allows for the creation of constrictions

Suspect Screening of Per- and Polyfluoroalkyl Substances in New Firefighter Turnout Gear Textiles

March 20, 2025
Author(s)
Andrew Maizel, Andre Thompson, Benjamin Place, Alix Rodowa, Jessica Reiner, Audrey Tombaugh, Halen Solomon, Brittany Stinger, Michelle Donnelly, Rick Davis
Firefighter turnout gear provides protection from exposure to flame, heat, and liquids, but has also been found to contain numerous per- and polyfluoroalkyl substances (PFAS). Previous examinations of PFAS in firefighter turnout gear have predominantly

The Development of Standards for the Ethical Use of Human Skeletal Remains for Education, Research, and Training in Forensic Anthropology

March 19, 2025
Author(s)
Nicholas Passalacqua, Eric Bartelink, Wendy McQuade, Dawnie Steadman, Donna Boyd, Kate Spradley, Kelly Sauerwein, Ranee Ho
We present a proposed standard regarding the use of contemporary human skeletal remains in education, training, and research contexts in forensic anthropology. This document was generated by the Anthropology subcommittee of the Organization of Scientific

On the Impact of Hydrogen Infiltration into Amorphous Oxide Transistor Performance during Forming Gas Annealing (FGA) and its Mitigation

March 18, 2025
Author(s)
Yu-Hsin Kuo, Dylan J. Matthews, Shinichiro N. Muramoto, TaeYoung Song, Chengyang Zhang, Xianduo Zhao, Md S. Rahman, Sanghyun Kang, Andres S. Aguirre, Seung M. Lee, Daewon Ha, Sourav Dutta, Theodore Moise, Jayakanth Ravichandran, Shimeng Yu, Alexander Grutter, Suman Datta, Tania Roy, Asif I. Khan
We present, for the first time, a CMOS-compatible and highly effective hydrogen barrier layer composed of thin Al2O3 and HfO2 films, integrated into ALD-based 4% W-doped In2O3-based amorphous oxide semiconductor (AOS) transistors. Following 4000 C FGA (4%

Magneto-optics of a charge-tunable quantum dot: Observation of a negative diamagnetic shift

March 17, 2025
Author(s)
Giora Peniakov, A Beck, Eilon Poem, Zu-En Su, Boaz Taitler, Sven Hofling, Garnett Bryant, David Gershoni
We present magneto-optical studies of a self-assembled semiconductor quantum dot in neutral and positively charged states. The diamagnetic shifts and Zeeman splitting of many well identified optical transitions are precisely measured. Remarkably, a

Detection limits of AI-based SEM dimensional metrology

March 14, 2025
Author(s)
Peter Bajcsy, Brycie Wiseman, Michael Paul Majurski, Andras Vladar
The speed of in-line scanning electron microscope (SEM) measurements of linewidth, contact hole, and overlay is critically important for identifying the measurement area and generating indispensable process control information. Sample charging and damage

Mission Critical Voice Roundtable Report

March 14, 2025
Author(s)
Alison Kahn, Lisa Soucy
This report summarizes discussions from the Mission Critical Voice Virtual Roundtable hosted by the Public Safety Communications Research (PSCR) Division of the National Institute of Standards and Technology (NIST) in April 2024. PSCR convened 37 first

NIST Cybersecurity Framework 2.0: Resource & Overview Guide (Japanese translation)

March 14, 2025
Author(s)
Kristina Rigopoulos, Stephen Quinn, Cherilyn Pascoe, Jeffrey Marron, Amy Mahn, Daniel Topper
The NIST Cybersecurity Framework (CSF) 2.0 can help organizations manage and reduce their cybersecurity risks as they start or improve their cybersecurity program. The CSF outlines specific outcomes that organizations can achieve to address risk. Other

A Spatially-Resolved Evaluation of Accelerated Environmental Aging on Emerging Polypropylene-based Photovoltaic Backsheets using Raman Spectroscopy

March 13, 2025
Author(s)
Ashlee Aiello, Stefan Mitterhofer, Jan Obrzut, Karissa Jensen, Patryk Wasik, Chiara Barretta, Gernot Oreski, Stephanie Watson, Li Piin Sung, Xiaohong Gu
Accelerated aging was used to assess environmental degradation in emerging co-extruded polypropylene (PP)-based backsheets under three different environmental conditions (65 °C/20 % relative humidity (RH), 75 °C/20 % RH, and 75 °C/50 % RH). Although
