Fatigue Life Assessment of Additively Manufactured Components Considering Surface Roughness
Background Additive manufacturing (AM) allows for the creation of highly complex parts, but the rough surfaces produced during the process can significantly reduce the fatigue life of these components. This issue is critical in industries such as aerospace and automotive, where parts experience repeated stress over time. Surface treatments, like polishing,...

DNA Methylation Barriers
In normal differentiated cells, most of the genome is densely methylated, except CpG islands near promoters of actively transcribed genes. Maintaining this boundary between unmethylated promoter-associated and adjacent methylated regions is crucial as loss of segregation can lead to disease. Unfortunately, it is not clear where these boundaries are,...

Multi-Aircraft Trajectory Prediction Using Bayesian Spatio-Temporal Graph Transformer Network
The escalation of civil aviation operations has led to the concept of the next generation air traffic management system (NextGen), which aims to efficiently and safely accommodate the growing air traffic flow within the U.S. airspace. Air Traffic Controller (ATC) workload is one of the main limitations to the capacity of the air traffic management...

Fracture Pattern Prediction with Random Microstructure using Deep Neural Network
Material fracture failure is a critical issue for many engineering structures and components. Accurate fracture prediction is necessary to ensure the safety of these structures and components. The finite element method (FEM) is a widely used approach for material mechanical modelling; however, FEM is known to have difficulties in solving problems...

Multi-fidelity Data Aggregation using Convolutional Neural Networks
In many domains in science and engineering, multiple computational and experimental models are generally available to describe a system of interest. These models differ from each other in the level of fidelity and cost. Typically, computationally or experimentally expensive high-fidelity (HF) models describe a system with a high accuracy. In...

Self-Expanding Stent for Valve Replacement
Aortic stenosis and aortic regurgitation are the most common types of aortic valvular diseases. Such diseased aortic valves in the body are traditionally replaced with valve prosthesis by an open surgical implantation. Available for licensing and commercial development is intellectual property covering stents for use with valve prostheses. As illustrated...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

And-1 Inhibition by DHS for Cancer Treatment
GW researchers developed DHS (4,4’-trans-dihydroxystilbene) as a new cytotoxic anticancer drug for use alone or in combination with other chemotherapies. Drug toxicity and drug resistance limit the ability of many cytotoxic cancer drugs to effectively treat cancer, a problem which is overcome by DHS. The cancer killing efficacy of DHS is...

JobViz: User Interface for Visualization of Majors & Jobs
Invention Summary: University (and industry) career search portals and web-based job search engines allow users to search on many items (e.g., education, location, level, etc.) and then present a text based list of potential job opportunities. University career portals are not as conductive to exploration by job and career searchers as they could...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...
