Abstract: A host material may be used for the separation of elements or compounds, wherein the host material is an organic molecular solid with suitable cavities for accommodating a guest material to be separated, and with interconnections between the cavities to allow the guest material to diffuse through the host material, and wherein said interconnections are closed for a proportion of the time or have a static pore limiting diameter which is smaller than the static dimension of the guest material. Applications include separations of rare gases, chiral molecules, and alkanes. One class of suitable host materials may be made by imine condensation.

Abstract: Systems and methods of adaptive streaming are discussed. Transcoded copies of a source stream may be aligned with one another such that the independently specified portions of each transcoded stream occur at the same locations within the content. These transcoded copies may be produced by one or more transcoders, whose outputs are synchronized by a delay adjuster. A fragmenter may use the synchronized and aligned streams to efficiently produce fragments suitable for use in adaptive streaming.

Abstract: Aspects of the disclosure relate to control of consumption of content in an appliance. The content can include linear programming and non-linear assets. Such control can permit (i) changing a channel in the appliance (e.g., a CPE without upstream functionality) and thus selecting a linear-programming asset, a non-linear asset, and so forth, and (ii) controlling consumption of such assets. In one aspect, a device with upstream network connectivity can control the consumption of media in the appliance. The device can leverage data management and control functionality of a service provider network to acquire information related to assets available for consumption and to transmit asset requests to the service provider network, which can transmit content and signaling to the appliance in accordance at least in part with the asset request, thus controlling media consumption in the appliance.
