Abstract: Provided herein are polymer materials that find use in, for example, delivery of short-chain fatty acids. In particular, polymers are provided that form stable nanoscale structures and release their payload, for example, by cleavage of a covalent bond (e.g., via hydrolysis or enzymatic cleavage). The polymers are useful, for example, for delivery of payloads (e.g., SCFAs) to the intestine for applications in health and treatment of disease, and have broad applicability in diseases linked to changes in the human microbiota including inflammatory, autoimmune, allergic, metabolic, and central nervous system diseases, among others.

Abstract: An embodiment may involve web page metadata that defines a web page, first sub-page metadata that defines a first sub-page, and second sub-page metadata that defines a second sub-page, wherein the web page metadata includes specification of a viewport, and wherein the viewport is associated with an identifier. One or more processors may be configured to: receive a request for the web page; resolve the web page metadata into web content, wherein resolving the web page metadata includes: (i) determining, based on the identifier, a route associated with the viewport, (ii) determining, based on the route, a set of conditions associated with the viewport, (iii) determining that a particular condition is satisfied, wherein the particular condition is associated with the first sub-page and (iv) placing, based on the particular condition being satisfied, the first sub-page metadata in the viewport; and transmit the web content.

Abstract: A UAV delivery control system is disclosed. Sensors detect operation parameters associated with the UAV as the UAV maneuvers along an airborne delivery route. A UAV operation controller monitors UAV route parameters as the UAV maneuvers along the airborne delivery route. The UAV route parameters are indicative as to a current environment of the airborne delivery route that the UAV is encountering. The UAV operation controller automatically adjusts the operation of the UAV to maintain the operation of the UAV within an operation threshold based on the operation parameters and the UAV route parameters. The operation threshold is the operation of the UAV that is maintained within an overall airborne operation radius of the UAV from a return destination thereby enabling the UAV to execute the delivery of the package along the airborne delivery route and to return to the return destination.
