Abstract: Disclosed are systems and methods for a Rich Communication Services (RCS) Proxy that can be enabled via a novel network element, which provides functionality for establishing and enabling emergency RCS communications. The disclosed RCS framework can facilitate simultaneous voice and chat features for an emergency services caller. With Session Initiation Protocol (SIP and Hypertext Transfer Protocol Secure (HTTPS) interfaces, the disclosed RCS framework can function to automatically establish an emergency chat session for RCS-capable devices. For devices that are not configured with RCS capabilities, the disclosed framework can function to provide a uniform resource locator (URL) via a short message/messaging service (SMS) message, such that via interaction with the URL, an internet session with the PSAP can be established. Accordingly, the disclosed RCS framework provides functionality for aligning voice and chat interactions between conversing entities (e.g.

Abstract: A device may receive, from a user device, a request to establish a voice call. The device may determine that one of a plurality of endpoints is to be involved in the voice call with the user device. The device may transmit send-only invites to the plurality of endpoints. The device may receive, from a first endpoint of the plurality of endpoints, a receive-only response. The device may transmit a send-receive invite to the first endpoint, wherein the send-receive invite identifies a selected communication protocol as a communication protocol for the voice call. The device may transmit a send-receive acceptance to the user device. The send-receive acceptance may identify the communication protocol for the voice call, and upon the user device receiving the send-receive acceptance, the voice call can be established between the user device and the first endpoint.

Abstract: In some implementations, an application server may receive, from a calling party user equipment, a call for a called party associated with multiple user equipment. The application server may provide to the multiple user equipment, and based on the call, a request for transcoding information associated with the multiple user equipment. The application server may assign a transcoding resource for handling the call, wherein the transcoding resource is provided in a network. The application server may receive, based on the request, the transcoding information from a particular user equipment of the multiple user equipment. The application server may provide the transcoding information to the transcoding resource, wherein the transcoding information causes the transcoding resource to establish and transcode the call between the calling party user equipment and the particular user equipment.

Abstract: A method for the in vivo production of 1,3-butadiene from 2,4-pentadienoate is described (FIG. 1). Enzymes capable of decarboxylating 2,4-pentadienoate to 1,3-butadiene have been discovered. Recombinant expression of these newly discovered enzymes has resulted in the engineering of microorganisms capable of producing 1,3-butadiene when cultured in the presence of 2,4-pentadienoate. 1,3-butadienoate is an important monomer used in the manufacturing of rubbers and plastics. This invention will help to enable the biological production of 1,3-butadiene from renewable resources such as sugar, for example.
