Generation of Neutron Airy Beams

July 28, 2024
Author(s)
Charles W. Clark, Dmitry Pushin, Michael G. Huber, Kirill Zhernenkov, Jonathan White, Lisa DeBeer-Schmitt, David Cory, Huseyin Ekinici, Melissa Henderson, Owen Lailey, Dusan Sarenac
The Airy wave packet is a solution to the potential-free Schr¨odinger equation that exhibits remark-able properties such as self-acceleration, non-diffraction, and self-healing. Although Airy beams are now routinely realized with electromagnetic waves and

A Plan for Global Engagement on AI Standards

July 26, 2024
Author(s)
Jesse Dunietz, Elham Tabassi, Mark Latonero, Kamie Roberts
Recognizing the importance of technical standards in shaping development and use of Artificial Intelligence (AI), the President's October 2023 Executive Order on the Safe, Secure, and Trustworthy Development and Use of Artificial Intelligence (EO 14110)

Artificial Intelligence Risk Management Framework: Generative Artificial Intelligence Profile

July 26, 2024
Author(s)
Chloe Autio, Reva Schwartz, Jesse Dunietz, Shomik Jain, Martin Stanley, Elham Tabassi, Patrick Hall, Kamie Roberts
This document is a cross-sectoral profile of and companion resource for the AI Risk Management Framework (AI RMF 1.0) for Generative AI, pursuant to President Biden's Executive Order (EO) 14110 on Safe, Secure, and Trustworthy Artificial Intelligence. The

Bilirubin measurements in neonates: uniform neonatal treatment can only be achieved by improved standardization

July 26, 2024
Author(s)
Christian Hulzebos, Johanna Camara, Miranda van Berkel, VINCENT DELATOUR, Stanley Lo, Agnes Mailloux, Marcel Schmidt, Mercy Thomas, Lindsey Mackay, Ronda Greaves
Measurement of total serum bilirubin (TSB) concentration is the gold standard approach for diagnosing neonatal unconjugated hyperbilirubinemia. It is of utmost importance that the measured TSB concentration is sufficiently accurate to prevent

Uncovering the Timescales of Spin Reorientation in TbMn6Sn6

July 26, 2024
Author(s)
Sinead Ryan, Anya Grafov, Na Li, Hans Nembach, Justin Shaw, Hari Bhandari, Tika Kafle, Richa Sapkota, Henry Kapteyn, Nirmal Ghimire, Margaret Murnane
TbMn6Sn¬6 is a ferrimagnetic material which exhibits a highly unusual phase transition near room temperature where spins remain collinear while the total magnetic moment rotates from out-of-plane to in-plane. The mechanisms underlying this phenomenon have

Superconducting phase diagram in BixNi1-x thin films: the effects of Bi stoichiometry on superconductivity

July 25, 2024
Author(s)
Jihun Park, Jarryd Horn, Dylan Kirsch, Rohit Pant, Hyeok Yoon, Sungha Baek, suchismita sarker, Apurva Mehta, Xiaohang Zhang, Seunghun Lee, Richard Greene, Johnpierre Paglione, Ichrio Takeuchi
The Bi–Ni binary system has been of interest due to possible unconventional superconductivity aroused therein, such as time-reversal symmetry breaking in Bi/Ni bilayers or the coexistence of superconductivity and ferromagnetism in Bi3Ni crystals. While Ni

Ranging Atom Probe Spectra to Reduce Measurement Bias

July 24, 2024
Author(s)
Frederick Meisenkothen, David Newton, Karen DeRocher, Mark McLean
Atom probe tomography (APT) is emerging as an essential characterization tool in a wide variety of science and engineering fields. For example, APT is helping to foster nascent fields, such as nano-geology [1], and is increasingly being adopted by the

Transmission Electron Imaging and Diffraction of Asbestos Fibers in an SEM

July 24, 2024
Author(s)
Jason Holm, Elisabeth Mansfield
Asbestos, a known carcinogen, can be found in consumer products ranging from building materials to textiles. While most of the products are no longer produced domestically, the release of asbestos fibers from these and other non-anthropogenic sources into

Cannabinoids detected in exhaled breath condensate after cannabis use

July 23, 2024
Author(s)
Jennifer Berry, Ashley Brooks-Russell, Cheryle Beuning, Sarah Limbacher, Tara Lovestead, Kavita Jeerage
Cannabinoids can be detected in breath after cannabis use, but different breath matrices need to be explored as studies to date with filter-based devices that collect breath aerosols have not demonstrated that breath-based measurements can reliably

Forecasting Operation of a Chiller Plant Facility Using Data Driven Models

July 23, 2024
Author(s)
Behzad Salimian Rizi, Afshin Faramarzi, Amanda Pertzborn, Mohammad Heidarinejad
In recent years, data-driven models have enabled accurate prediction of chiller power consumption and chiller coefficient of performance (COP). This study evaluates the usage of time series Extreme Gradient Boosting (XGBoost) models to predict chiller

Measurement-driven Langevin modeling of superparamagnetic tunnel junctions

July 23, 2024
Author(s)
Liam Pocher, Temitayo Adeyeye, Sidra Gibeault, Philippe Talatchian, Ursula Ebels, Daniel Lathrop, Jabez J. McClelland, Mark Stiles, Advait Madhavan, Matthew Daniels
Superparamagnetic tunnel junctions are important devices for a range of emerging technologies, but most existing compact models capture only their mean switching rates. Capturing qualitatively accurate analog dynamics of these devices will be important as

NIST Risk Management Framework (RMF) Small Enterprise Quick Start Guide

July 23, 2024
Author(s)
Daniel Eliot
For organizations of all sizes, managing risk (including information security and privacy risk), is critical for organizational resilience. This guide is designed to help small, under-resourced entities understand the value and core components of the NIST
