Experiments to Test the A-UGV Capabilities Standard

December 8, 2021
Author(s)
Soocheol Yoon, Roger V. Bostelman, Ann Virts
Automatic, Automated, or Autonomous - Unmanned Ground Vehicles (A-UGVs), as referred to by ASTM International Committee F45, are industrial vehicles that have capabilities to navigate, dock, avoid obstacles, and interact with other vehicles and systems all

HDX-MS and MD simulations provide evidence for stabilization of the IgG1- FcgRIa (CD64a) immune complex through intermolecular glycoprotein bonds

December 8, 2021
Author(s)
Kyle Anderson, Kerry Scott, Christina Bergonzo, Ioannis Karageorgos, Elyssia Gallagher, Venkata Tayi, Michael Butler, Jeffrey W. Hudgens
Previous reports present different models for the stabilization of the Fc—FcγRI immune complex. Although accord exists on the importance of L235 in IgG1 and some hydrophobic contacts for complex stabilization, discord exists regarding the existence of

A Data Integration Framework for Additive Manufacturing Big Data Management

December 7, 2021
Author(s)
Milica Perisic, Dimitrije Milenkovic, Yan Lu, Albert T. Jones, Nenad Ivezic, Boonserm Kulvatunyou
Large amounts of data are generated throughout the entire, AM, part-development lifecycle. Data are generated by various functions within process monitoring, material characterization, equipment status, and part qualification. Hence, data integration and

On Convergence of the Upper Bound on the Ratio of Gain to Quality Factor

December 6, 2021
Author(s)
Alex Yuffa, Marc Valdez, Benoit Derat
An antenna's practical far-field distance can be estimated from the upper bound on the ratio of its gain to quality factor. This upper bound is an infinite series that can be truncated based on the desired far-field accuracy. We investigate the convergence

Computational scanning tunneling microscope image database

December 5, 2021
Author(s)
Kamal Choudhary, Kevin Garrity, Charles Camp, Sergei Kalinin, Rama Vasudevan, Maxim Ziatdinov, Francesca Tavazza
We introduce the systematic database of scanning tunneling microscope (STM) images obtained using density functional theory (DFT) for two-dimensional (2D) materials, calculated using the Tersoff-Hamann method. It currently contains data for 716 exfoliable

How Austenitic is a Martensitic Steel Produced by Laser Powder Bed Fusion? A Cautionary Tale

December 2, 2021
Author(s)
Fan Zhang, Mark R. Stoudt, Souzan Hammadi, Carelyn E. Campbell, Eric A. Lass, Maureen E. Williams
Accurate phase fraction analysis is an essential element of microstructural characterization of alloys and often serves as a basis to quantify effects such as heat treatment or mechanical deformation. Additive manufacturing (AM) of metals, due to the
