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,...

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...

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...

IoT-Compatible Spatial Audio System for a Moving User

Background Current spatial audio techniques for speaker systems are challenged by high cost, high computational intensity, and user mobility. In particular, crosstalk—when sound from a speaker unintentionally reaches an opposite ear—is a major performance-degrading factor. Some spatial audio speaker systems utilize beam-forming techniques...

Shifting Weight-Based Interfaces for Simulated Hydrodynamics in Mixed-Reality Fluid Vessels (SWISH)

Background By integrating visual stimuli with perceived tactile sensation, mixed-reality haptic devices provide a critical dimension to otherwise intangible virtual content. Much of the commercial and academic efforts in this domain have focused on delivering simulated interactions with rigid objects, often through the use of vibrotactile gloves, robotic...

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...

All-Fiber Multicore Fiber Laser Devices

Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
