Abstract: In some aspects, the disclosure is directed to methods and systems for in-application dynamic content loading via a hybrid process, including both local and remote content items, via a content handler intercepting requests in a predetermined uniform resource locator (URL) scheme and redirecting the requests to local storage or a remote content provider, transparently to a browser application or webview of the application, and avoiding restrictions imposed by an operating system of the device. Content may be dynamically updated on the content provider server by developers, and dynamically loaded during execution of the application on client devices, without requiring updates to be provided to an application store or publisher server.

Abstract: Embodiments provide a multi-cone X-ray imaging Bragg crystal spectrometer for spectroscopy of small x-ray sources with a well-defined spectral resolution. The spectrometer includes a glass substrate machined to a multi-cone form; and a thin crystal slab attached to the glass substrate, whereby the multi-cone X-ray imaging Bragg crystal spectrometer provides rotational symmetry of a ray pattern, providing for accurate imaging, for each wavelength in the spectral range of interest. One or more embodiments include a streak camera and/or a gated strip detector.
