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

Computational and Theoretical Study of Colloidal Monolayers with Short-Range Attractions and Dipolar Repulsions

March 21, 2025
Author(s)
Chieh-Chih Yeh, Harold Hatch, Adithya Sreenivasan, Bhuvnesh Bharti, Vincent Shen, Zachary Sherman, Thomas Truskett
This study explores the structure and phase behavior of monolayers of model colloids with short-range attractions and long-range repulsions, The model is motivated by recent experiments of hard-sphere-like microspheres that effectively interact via

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

METROLOGY FOR MRI: THE FIELD YOU'VE NEVER HEARD OF

March 19, 2025
Author(s)
Kathryn Keenan, Stephen Russek, Matt Hall
Quantitative MRI has been an active area of research for decades and has produced a huge range of approaches with enormous potential for patient benefit. In many cases, however, there are challenges with reproducibility which has hampered clinical

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

Scalable and fault-tolerant preparation of encoded k-uniform states

March 18, 2025
Author(s)
Shayan Majidy, Madelyn Cain, Nishad Maskara, Dominik Hangleiter, Michael Gullans
k-uniform states are valuable resources in quantum information, enabling tasks such as teleporta- tion, error correction, and accelerated quantum simulations. However, verifying k-uniformity is as difficult as measuring code distances, and devising fault

Detection of fractional quantum Hall states by entropy-sensitive measurements

March 17, 2025
Author(s)
Nishat Sultana, Robert Rienstra, K Watanabe, T Taniguchi, Joseph Stroscio, Nikolai Zhitenev, D Feldman, Fereshte Ghahari Kermani
Measurements of the thermopower of a clean two-dimensional electron system is directly proportional to the entropy per charge carrier1 which can probe strongly interacting quantum systems ranging from black holes2 to the fractional quantum Hall effect

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
