Towards a Markerless 3D Pose Estimation Tool

April 28, 2023
Author(s)
Amaan Rahman, Mili Shah, Ya-Shian Li-Baboud, Ann Virts
Evaluation of exoskeleton performance benefts from standards to verify proper functionality and safety. Currently, there are limited evaluation methods for exoskeletons. Measurement methods to evaluate human-exoskeleton kinematics include optical tracking

Model Validation for Scanning Electron Microscopy

April 27, 2023
Author(s)
Olga Ridzel, Wataru Yamane, Ishiaka Mansaray, John S. Villarrubia
We are beginning projects to validate the physics models used for interpretation of electron microscopy images. In one, we will measure electron yields and energy spectra from cleaned well-characterized samples subjected to electron bombardment inside of a

Proof-of-Principle Experiment for Testing Strong-Field Quantum Electrodynamics with Exotic Atoms: High Precision X-Ray Spectroscopy of Muonic Neon

April 27, 2023
Author(s)
Douglas Bennett, W.Bertrand (Randy) Doriese, Malcolm Durkin, Joseph Fowler, Johnathon Gard, Gene C. Hilton, Kelsey Morgan, Galen O'Neil, Carl D. Reintsema, Dan Schmidt, Daniel Swetz, Joel Ullom, Takuma Okumura
To test the bound-state quantum electrodynamics (BSQED), we have performed high precision x- ray spectroscopy of the 5g→4f and 5f→4d transitions (BSQED contribution of 2.4 eV and 5.2 eV, respectively) of muonic neons in the low-pressure gas phase under the

Optimizing Product Life Cycle Systems for Manufacturing in a Circular Economy

April 26, 2023
Author(s)
Buddhika Hapuwatte, Nehika Mathur, Noah Last, Vincenzo Ferrero, Maya Reslan, KC Morris
Global population growth and increasing resource scarcity are necessitating sustainable manufacturing and circular economy (CE) practices. These practices require the decisions made at each product life cycle (PLC) stage consider sustainability and

AI for Materials

April 25, 2023
Author(s)
Debra Audus, Kamal Choudhary, Brian DeCost, A. Gilad Kusne, Francesca Tavazza, James A. Warren
The application of artificial intelligence (AI) methods to materials re- search and development (MR&D) is poised to radically reshape how materials are discovered, designed, and deployed into manufactured products. Materials underpin modern life, and

Bearing area curve based partitioning for the verification of theoretical supplemental geometry on additively manufactured lattice structures

April 25, 2023
Author(s)
Maxwell R. Praniewicz, Jason Fox, Lucas Fournet-Fayard, Charles Cayron, Imade Koutiri, Anne-Francoise Obaton
The geometrical qualification of additively manufactured lattice structures has largely focused on the measurement of strut diameter, form variations, and surface texture. However, the exterior surfaces of the lattice structure, defined through theoretical

Mechanical Regulation of Oral Epithelial Barrier Function

April 25, 2023
Author(s)
Eun Jin Lee, Paul Salipante, Anthony Kotula, Dana Graves, Stella Alimperti, Yoontae Kim
Epithelial cell function is modulated by mechanical forces imparted by the extracellular environment. The transmission of forces onto the cytoskeleton by modalities such as mechanical stress and matrix stiffness is necessary to address by the development

Phishing With a Net: The NIST Phish Scale and Cybersecurity Awareness

April 25, 2023
Author(s)
Shanee Dawkins, Jody Jacobs
Orienting an entire organization toward sound security practices is an important, but non-trivial undertaking. A starting point for many organizations is to build a robust security awareness program, training employees to recognize and respond to security

Noise-resilient deep tomographic imaging

April 24, 2023
Author(s)
Zhen Guo, Zhiguang Liu, George Barbastathis, Qihang Zhang, Michael Glinsky, Bradley Alpert, Zachary H. Levine
X-ray tomography is a non-destructive imaging technique that reveals the interior of an object from its projections at different angles. Under limited-angle and low-photon sampling, a regularization prior is required to retrieve a high-fidelity
