Patent number: 11851711Abstract: Cancer specific DNA methylation regions have been studied to find cancer specific DNA methylation markers for most common cancers. Differentially methylated regions for individual cancer types were identified and those were further filtered against data from normal tissues to obtain marker regions with cancer specific methylation, resulting in total of 1,250 hypermethylated and 584 hypomethylated marker CpGs. Optimal sets of six markers for each TCGA cancer type that could identify most tumors with high specificity and sensitivity (AUC 0.969-1.00) were chosen from hypermethylated markers and a universal 12 marker set that can detect tumors of all 33 TCGA cancer types (AUC>0.84) was also chosen from hypermethylated markers.Type: GrantFiled: October 1, 2018Date of Patent: December 26, 2023Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Lukas Vrba, Bernard W.

Patent number: 11846032Abstract: Catalyst systems employing inexpensive and readily-available protic co-catalysts to increase a proton reduction rate in a hydrogen evolution reaction (HER) are described herein. The protic co-catalysts function to increase the rate without being consumed in the process of water splitting to hydrogen and oxygen. They may simultaneously serve to stabilize the pH of the water and be the electrolyte to carry the current for the electrolytic splitting of water. The protic co-catalysts also decrease the overpotential energy requirement for the process of water splitting. These protic co-catalysts can be used with both heterogeneous and homogenous catalysts, as well as assist photocatalysis and other processes for the reduction of protons.Type: GrantFiled: December 11, 2018Date of Patent: December 19, 2023Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Dennis Lichtenberger, Richard S.

Patent number: 11803059Abstract: A display placed in an optical pathway extending from an entrance pupil of a person's eye to a real-world scene beyond the eye. The display includes at least one 2-D added-image source that is addressable to produce a light pattern corresponding to a virtual object. The source is situated to direct the light pattern toward the person's eye to superimpose the virtual object on an image of the real-world scene as perceived by the eye via the optical pathway. An active-optical element is situated between the eye and the added-image source at a location that is optically conjugate to the entrance pupil and at which the active-optical element forms an intermediate image of the light pattern from the added-image source. The active-optical element has variable optical power and is addressable to change its optical power to produce a corresponding change in perceived distance at which the intermediate image is formed, as an added image to the real-world scene, relative to the eye.Type: GrantFiled: December 16, 2020Date of Patent: October 31, 2023Assignee: THE ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Hong Hua, Sheng Liu

Publication number: 20230342650Abstract: We disclose optical entanglement distribution in quantum networks based on a quasi-deterministic entangled photon pair source. Combining heralded photonic Bell pair generation with spectral mode conversion to interface with quantum memories eliminates switching losses due to multiplexing in the source. This zero-added-loss multiplexing (ZALM) Bell pair source is especially useful for the particularly challenging problem of long-baseline entanglement distribution via satellites and ground-based memories, where it unlocks additional advantages: (i) the substantially higher channel efficiency ? of downlinks versus uplinks with realistic adaptive optics, and (ii) photon loss occurring before interaction with the quantum memory—i.e., Alice and Bob receiving rather than transmitting—improve entanglement generation rate scaling by (?{square root over (?)}).Type: ApplicationFiled: February 22, 2023Publication date: October 26, 2023Applicants: Massachusetts Institute of Technology, Arizona Board of Regents on Behalf of the University of ArizonaInventors: Kevin Chen, Prajit Dhara, Saikat Guha, Dirk Robert ENGLUND
