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

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

Certification of Standard Reference Material(R) 2983 Inorganics in Geoduck Clam Tissue (Panopea generosa)

January 29, 2024
Author(s)
Colleen E. Bryan Sallee, Melannie Bachman, Steven J. Christopher, Debra Ellisor, Michael Ellisor, Jennifer Hoguet, Samuel Huntington, Caleb Luvonga, Amanda Moors, Dhayaalini Nadarajan, Tomohiro Narukawa, Jennifer Ness, Rebecca Pugh, James H. Yen, Lee L. Yu
Standard Reference Material (SRM) 2983 Inorganics in Geoduck Clam Tissue (Panopea generosa) is intended to be used for the evaluation of methods for the determination of elements, arsenic species, and proximates in this and similar matrices. A unit of SRM

Noncollinear 2k Antiferromagnetism in the Zintl Semiconductor Eu5In2Sb6

January 29, 2024
Author(s)
Vincent Morano, Jonathan N. Gaudet, Nicodemos Varnava, Tanya Berry, Thomas Halloran, Chris Lygouras, Xiaoping Wang, Christina M. Hoffman, Guangyong Xu, Jeffrey Lynn, Tyrel McQueen, David Vanderbilt, Collin L. Broholm
Eu5In2Sb6 is an orthorhombic non-symmorphic small band gap semiconductor with three distinct Eu2+ sites and two low-temperature magnetic phase transitions. The material displays one of the greatest (negative) magnetoresistances of known stoichiometric

Building Fire Hazard Predictions Using Machine Learning

January 26, 2024
Author(s)
Eugene Yujun Fu, Wai Cheong Tam, Tianhang Zhang, Xinyan Huang
The lack of information on the fire ground has always been the leading factor in making wrong decisions . Wrong decisions can be made by individual firefighters, their local chiefs, and/or the incident commander. Any wrong decision at any level (scale)

New Fire Protection Materials

January 26, 2024
Author(s)
Andre Thompson
Residential upholstered furniture (RUF) is the leading combustible in fatal fires in the United States. In the last few decades, fire-retardant (FRs) chemicals have been largely used in attempt to reduce RUF flammability; however, concerns about possible
