Magnetic Skin Effect in Pb(Fe1/2Nb1/2)O3

July 29, 2024
Author(s)
Nathan Giles-Donovan, A. D. Hillier, K Ishida, B.V. Hampshire, S. Giblin, B. Roessli, Peter M. Gehring, Guangyong Xu, Xiaobing Li, Haosu Luo, Sandy Cochran, C. Stock
Relaxor-ferroelectrics display exceptional dielectric properties resulting from the underlying random dipolar fields induced by strong chemical inhomogeneity. An unusual structural aspect of relaxors is a skin-effect where the near-surface region in single

Similarity Measures of Mass Spectra in Hilbert Spaces

July 29, 2024
Author(s)
Anthony J. Kearsley, Matthew Roberts
Mass spectrometry (MS) is an analytic tool for measuring mass-to-charge ratios of molecules or molecular fragments. It is often used to identify and classify compounds. A mass spectrometer measures the mass of molecules and produces a signal proportional

Super-resolution Localization and Tracking in WiFi Sensing

July 29, 2024
Author(s)
Jian Wang, Jack Chuang, Nada Golmie
Integrated sensing and communication (ISAC) systems have been investigated by the research and standardization communities in the recent past. Accurate localizing the target and tracking the target's movement are critical for numerous smart Internet of

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
