Abstract: A system and method are disclosed for merging multiple spreadsheets into one sheet, and/or exchanging data among the sheets, by expressing each sheet's formulae as an algebraic (equational) theory and each sheet's values as a model of its theory, and then performing one or more of “Kan-extension”, “psuedo-colimit”, and “lifting”, and constructions from category theory, to compute a canonically “universal” integrated theory and model, which can then be expressed as a spreadsheet and from which projections back to the sources are easily constructed.

Abstract: Aspects of the disclosure are directed to an artificial reality (XR) browser configured to trigger an immersive experience. Implementations display an element at a browser chrome of the XR browser when an immersive experience is loaded. For example, the XR browser can include an application programming interface (API) that supports configuration of a browser chrome element by components of a webpage. The API call can cause the display of the browser chrome element, change a display property for the browser chrome element, or configure the browser chrome element in any other suitable manner. Upon receiving input at the browser chrome element (configured by the API call), the XR browser can transition from displaying a two-dimensional panel view of a webpage supported by loaded web resources (e.g., hypertext transfer protocol (HTTP) pages, graphic images, etc.) to a three-dimensional environment supported by preloaded immersive resources (e.g., three-dimensional models, graphic images, etc.

Abstract: In some implementations, the disclosed systems and methods a user can be at a source location (e.g., XR environment, two-dimensional webpage/browser, etc.) and input received can trigger traveling the user to a target XR environment (e.g., an immersive environment). In some implementations, the disclosed systems and methods a user can spawn a virtual portal in an origin virtual world for travel to a destination virtual world for the creating user and a group of other users having avatars near that of the creating user. In some implementations, the disclosed systems and methods a user can be at a source location (e.g., XR environment, two-dimensional webpage/browser, etc.) and input received can trigger traveling the user to a target XR environment (e.g., an immersive environment).

Abstract: Hypochlorite salts and substantially dehydrated acid-form cation exchange resin beads are combined at specified ratios within a porous enclosure such as a pouch or sachet. Hypochlorous acid solutions are produced on demand by introducing the mixture-containing pouch into a chemical excess of water. Spontaneous exchange reactions occur at room temperature within a few minutes to produce aqueous hypochlorous acid, while the cations from the hypochlorite salt are simultaneously sequestered by the resin beads. The resin beads remain contained within the original porous enclosure to allow mechanical isolation or separation from the resulting solution.

The third wafer includes micromechanical elements. The third wafer is bonded to the dielectric layer, and the micromechanical elements are contained within the cavity.

Abstract: Techniques are described herein for automated bone mineral density and fracture risk assessment from digital X-rays. A method includes: obtaining image data including information relating to cortical bone tissue of at least a part of a first bone; preprocessing the image data, by isolating a region of interest in the image data, to generate preprocessed image data; applying the preprocessed image data as inputs across a trained machine learning model to generate output indicative of bone mineral density of the first bone; determining a T-score value based on the bone mineral density of the first bone; and providing, on a user interface, an output based on the T-score value.

Abstract: Embodiments of a 3D web interaction system are disclosed that allow a user to select a content item from a browser, displayed in an artificial reality environment, and present a corresponding version of the content item in the artificial reality environment. The 3D web interaction system can create the version of the selected content item in different ways depending on whether the selected content item is associated with 3D content and, if so, the type of the associated 3D content. For example, the 3D web interaction system can create and present different versions of the selected content item depending on whether the selected content item is(a) not associated with 3D content, (b) associated with “environment content,” or (c) associated with one or more 3D models.
