Recommendation for Key Derivation Using Pseudorandom Functions

February 2, 2024
Author(s)
Lily Chen
This Recommendation specifies techniques for the derivation of additional keying material from a secret key—either established through a key-establishment scheme or shared through some other manner—using pseudorandom functions: HMAC, CMAC, and KMAC.

Toward pluripotent materials through tempering of dynamic covalent polymer networks

February 2, 2024
Author(s)
Anthony Kotula, Nicholas Boynton, Joseph Dennis, Neil Dolinski, Charlie Lindberg, Garrett Grocke, Stephanie Vivod, Shrayesh Patel, Stuart Rowan
Pluripotency is defined as a system not fixed as to its developmental potentialities. While stem cells and pluripotent materials have heretofore been synonymous, a synthetic analog would lead to significant advancements in materials design for resource

Ability to simulate laser absorption and melt pool dynamics in solid aluminum: results and insights from the 2022 asynchronous AM-Bench challenge

February 1, 2024
Author(s)
Brian Simonds, Jack Tanner, Alexandra Artusio-Glimpse, Niranjan Parab, Cang Zhao, Tao Sun, Paul A. Williams
The 2022 Asynchronous AM-Bench challenge was designed to test the ability of simulations to accurately predict laser power absorption as well as various melt pool behaviors (width, depth, and solidification) during laser melting of solid metal during

Compartment fires: challenges for fire modeling as a tool for safe design

February 1, 2024
Author(s)
Tarek Beji, Talal Fateh, Jason Floyd, hugues Pretrel, Anthony Hamins
The use of fire models to support fire protection engineering decisions requires an understanding of model shortcomings and assurance in their predictive robustness. This note is a summary of the online 'compartment fire' workshop that was organized prior

Cybersecurity Framework Election Infrastructure Profile

February 1, 2024
Author(s)
Gema Howell, Mary C. Brady, Julie Snyder, David Weitzel, M. Schneider, Christina Sames, Joshua Franklin
This document is a Cybersecurity Framework Profile developed for voting equipment and information systems supporting elections. This Election Infrastructure Profile can be utilized by election administrators and IT professionals managing election

Data Requirements for a Digital Twin of a Robot Workcell

February 1, 2024
Author(s)
Deogratias Kibira, Guodong Shao
The applications of digital twins continue to grow with the volume and variety of data collected. These data support the modeling of function, behavior, and structure of a physical element. However, successfully building a digital twin requires data

Emission Ghost Imaging: reconstruction with data augmentation

February 1, 2024
Author(s)
Kevin J. Coakley, Heather H. Chen-Mayer, Bruce D. Ravel, Daniel Josell, Nikolai Klimov, Sarah Robinson, Daniel S. Hussey
Ghost Imaging enables 2D reconstruction of an object even though particles transmitted or emitted by the object of interest are detected with a single pixel detector without spatial resolution. This is possible because the incident beam is spatially

Life-Cycle Analysis Datasets for Regionalized Plastic Pathways

February 1, 2024
Author(s)
Taemin Kim, Pahola Benavides, Joshua Kneifel, Kate Beers, Zifeng Lu, Troy Hawkins
The carbon intensity (CI) of producing five different resins – polyethylene terephthalate (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), and polyvinyl chloride (PVC) – in four different international regions –

Optimizing Implementations of Boolean Functions

January 31, 2024
Author(s)
Meltem Sonmez Turan
Symmetric cryptography primitives are constructed by iterative applications of linear and nonlinear layers. Constructing efficient circuits for these layers, even for the linear one, is challenging. In 1997, Paar proposed a heuristic to minimize the number

Tuning the Magnetic Anisotropy in artificially layered Mn3GaN/Mn3Ga Superlattices

January 31, 2024
Author(s)
Lu Guo, Neil Campbell, Alexander Grutter, Gahee Noh, Tianxiang Nan, P. Quarterman, Si-Young Choi, Thomas Tybell, Mark Rzchowski, Chang-Beom Eom
Artificially layered superlattices with two distinct spin structures offer new opportunities for manipulation of magnetic properties and interfacial spin configurations. We have grown epitaxial, coherent superlattices of ferrimagnetic Mn3Ga and

Low-noise microwave generation with an air-gap optical reference cavity

January 30, 2024
Author(s)
Yifan Liu, Dahyeon Lee, Takuma Nakamura, Naijun Jin, Haotian Cheng, Megan Kelleher, Charles McLemore, Igor Kudelin, William Groman, Scott Diddams, Peter Rakich, Franklyn Quinlan
We demonstrate a high finesse, microfabricated mirror-based, air-gap cavity with volume less than 1 ml, constructed in an array, that can support low-noise microwave generation through optical frequency division. We use the air-gap cavity in conjunction

Operando analysis of the positive active mass of lead batteries by neutron diffraction

January 30, 2024
Author(s)
Miguel Rodriuqez-Goemz, Javier Campo, Aloida Orera, Fernando de La Fuente, Jesus Valenciano, Holger Fricke, Yan Chen, Ke An, Daniel Hussey, Angel Larrea
We have analysed, through neutron diffraction experiments with the volume-gauge technique, the in operando performance of lead cells composed of industrial positive and negative electrodes, previously tank formed in the manufacturing plant. The cells, 6.5

Topological Hall effect induced by chiral fluctuations in a kagome lattice

January 30, 2024
Author(s)
Kyle Fruhling, Alenna Streeter, Sougata Mardanya, Xiaoping Wang, Priya Baral, Oksana Zaharko, Igor Mazin, Sugata Chowdhury, William Ratcliff, Fazel Tafti
Topological Hall effect (THE) is a hallmark of scalar spin chirality, which is found in static skyrmion lattices. Recent theoretical works have shown that scalar spin chirality could also emerge dynamically from thermal spin fluctuations. Evidence of such

Use Cases for Secure and Trusted Granular Data Sharing Among Disparate Databases

January 30, 2024
Author(s)
Joanna DeFranco, David Ferraiolo, Joshua Roberts, D. Richard Kuhn
Sharing data among disparate organizations can be extremely difficult, when the data comes from different database management systems (DBMS). Most problematic is that data stored at another organization most likely uses different DBMS schemas and
