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,...

Metabolic activity diffusion imaging (MADI): dye-free, high-resolution MRI metabolic imaging

Summary The current technology is a contrast agent-free method of metabolic imaging based on detection of Na/K ATPase activity with MRI, that provides significantly higher resolution than current approaches such as PET. Technology Overview Measuring metabolic activity in vivo can facilitate diagnoses of disease states and therapeutic responses....

A Gamma-ray Photon Counting Detector Based on Side-readout of Monolithic Scintillator Layers

Researchers at the University of Arizona have developed a gamma-ray photon counting device that works similarly to PET, but with a novel architecture that improves the accuracy and speed in determining the location of the biological targets, and is less costly to manufacture. Background: Positron Emission Tomography (PET) is a common and reliable...

Intelligent Multi-Beam Medium Access Control in Ku-Band for Mission-Oriented Mobile Mesh Networks

The Problem: There are existing similar technologies, but these technologies are not designed for mobile mission-oriented applications. The use of Ku-band frequency on two separate information transmission levels reduces interference common with current multi-beam antennas. Also, the Ku-band frequency is not the currently used frequency range...

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...

Close Range PET

This invention involves moving the detector ring of a PET system closer to the patient while improving the spatial resolution and reducing the blurriness of resulting images. By moving the detector module closer, the quantity of samples tested, and the solid angle covered by the scanner are increased. Background: Currently, PET system’s sensitivity...
