Self-neutralizing air-breathing thruster and method of neutralization
An ion-engine is the cutting edge for atmospheric air-breathing engines. The technology depends on ionizing and neutralizing atmospheric air particles which create thrust. This unique possibility makes it an ideal choice for very-low-orbit satellites. Very- low-orbit satellite capabilities have benefits such as higher resolution for images, weight...

Patient-Specific Brain Networks from BOLD-fMRI
Summary: A method for analysing functional magnetic resonance (fMRI) images to identify brain networks in task and resting-state experiments. What Blood-oxygen-level dependent functional MRI (BOLD-fMRI) measures change in neuronal activity by detecting alterations in brain blood oxygenation. High oxygenation levels are associated with increased...

Non-Invasive Plasma Discharge Tube Device for Treating Brain Tumors
Treating brain tumors, like glioblastoma, is challenging. Current glioblastoma drugs, Rapamycin and Temozolomide (TMZ), generally only extend life for a matter of months, are not very effective in treating recurring tumors, and have significant clinical toxicity. A novel Plasma Discharge Tube (PDT) device has the potential to be more effective and less...

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...

Cold atmospheric plasma-stimulated media for treating cancers
For successful cancer therapy, the most important aspect is selective eradication of cancer cells without damaging healthy cells. Cancer cells and normal cells have different thresholds for tolerance of reactive oxygen species (ROS) and reactive nitrogen species (RNS) before cell death (apoptosis) is induced. Previously, GW researchers invented a cold...

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...
