CNN Architecture for Disease Identification from Retinal Images
The rise of artificial intelligence is changing the shape of many different fields, and ophthalmic medicine is no exception. Convolutional neural networks (CNNs) have achieved remarkable results in the assisted diagnosis of ophthalmic diseases. However, they face challenges such as limited labeling and small dataset sizes. In recent years, self-supervised...

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,...

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...

A Mechanism and Method for Synthesis of a 2-D Gamma-ray Pinhole Projection Image from a Plurality of Slit Projection Images
This invention is a 3D medical imaging technique that incorporates single photon emission computed tomography (SPECT) to image radioisotope distributions, which are generally used to detect/monitor cancer, drug delivery, etc. This imaging technique uses SPECT to take 2D and 3D tomographic images of radioisotope distributions, both of which can be analyzed...

Amphiphilic macromolecules with novel hydrophobic segments
Invention Summary: Cardiovascular diseases are the leading cause of mortality in developed countries. Atherosclerosis, defined as the buildup of lipid rich plaques within the vascular intima, is the foremost pathology underlying these conditions. This causes irregular uptake of oxidized low-density lipoproteins (OxLDL) which leads...

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...
