Albert Davydov, Hari "Bhandari ", Zhenhua Ning, Po-Hao Chang, Peter Siegfried, Resham Regmi, Mohamed El Gazzah, Allen Oliver, Liqin Ke, Igor Mazin, Nirmal Ghimire
The unique connectivity of kagome lattices gives rise to topological properties such as flat bands and Dirac cones. When combined with ferromagnetism and with the chemical potential near the 2D Dirac points, this structure offers potential for realizing

Measuring social consensus

November 18, 2024
Author(s)
David W. Flater
Many organizations describe their processes as consensus-driven, but there is no consensus on the definition of consensus. Qualitative definitions of consensus prioritize social phenomena like "unity" that are not necessarily measurable. Quantitative

Author(s)
Alec Saville, Adriana Eres-Castellanos, Andrew Kustas, Levi Van Bastian, Donald Susan, Dale Cillessen, Sven Vogel, Natalie Compton, Kester Clarke, Amy Clarke
Controlling microstructural evolution in metallic additive manufacturing (AM) is difficult, especially in producing refined as-built grains instead of coarse, directional grains. Traditional solutions involve adding inoculants to AM feedstocks, but

Hydrogen Embrittlement Susceptibility and Fracture Toughness Measurements of Welded X65M Pipeline Steels

November 14, 2024
Author(s)
Newell Moser, Zack Buck, Nicholas Derimow, May Ling Martin, Damian Lauria, Enrico Lucon, Peter Bradley, Matthew Connolly
Hydrogen is known to deteriorate the mechanical performance of steels (i.e., hydrogen embrittlement). The welding processes involved in the manufacturing and joining of steel pipelines locally modifies the microstructure of the steel, further complicating

Hardware Security Failure Scenarios

November 13, 2024
Author(s)
Peter Mell, Irena Bojanova
Historically, hardware has been assumed to be inherently secure. However, chips are both created with software and contain complex encodings (e.g., circuit designs and firmware). This leads to bugs, some of which compromise security. This publication
