Publication number: 20230386039Abstract: Many biologic processes taking place inside a living organism are unpredictable in time and space, and cannot be known exactly. These mechanisms and interactions among them are better modeled as physiological random processes, the statistics of which are fully described by joint characteristic functionals.

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

Patent number: 11795248Abstract: Sulfur copolymers and methods of synthesizing said sulfur copolymers are described herein. Sulfur monomers copolymerize with epoxide or vinylic moieties the epoxy-functionalized styrenic comonomers to form a crosslinked network of the sulfur copolymer. Sulfur copolymers having high sulfur content are used as raw materials in 3D printing. Chalcogenide-based copolymers can utilize selenium to provide for the optical properties. Using an inverse vulcanization method, chalcogenic sulfur copolymers are used to prepare chemically stable polymer plastic materials with tunable optical and thermochemical properties. Optical substrates, such as films, waveguides, and molded (nano-, micro-) objects and lenses, are constructed from sulfur copolymers via 3D printing and are substantially transparent in the visible and infrared spectrum.Type: GrantFiled: January 22, 2021Date of Patent: October 24, 2023Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventor: Dong-Chul Pyun
