Abstract: Plant-based supple and durable topcoats are achieved by reacting naturally derived epoxides with naturally derived polyfunctional carboxylic acids. The topcoats are coated to various types of substrates including weaved or knitted or nonwoven fabrics, and can show significant advantages of replacing both animal hide leathers and petroleum-based PU leathers by reducing the carbon footprints, and improving environmental sustainability.

Abstract: A P-type gate HEMT device includes a substrate, a buffer layer, a channel layer, and a barrier layer sequentially arranged from bottom to top. A first P-type material layer is arranged on the barrier layer. A first source and a first drain are respectively arranged on two sides of the first P-type material layer. A first conductive layer is arranged on the first P-type material layer. A second P-type material layer is connected to the first P-type material layer. A second conductive layer is connected to the second P-type material layer. A third conductive layer is connected to the second P-type material layer. The first P-type material layer, the first source, the first drain, and the first conductive layer form a normally-off N-channel transistor. The second P-type material layer, the second conductive layer, and the third conductive layer form a normally-on P-channel transistor.

Abstract: The present disclosure relates to user communication devices and communication network devices, both arranged to support grouping of user communication devices in a communication network. One example user communication device determines a neighbor user communication device set comprising the user communication device and neighbor user communication devices, and determines, by communicating with the neighbor user communication devices of the neighbor user communication device set via D2D communication, a user communication device group that the user communication device joins. The communication network device receives information on a plurality of user communication device groups, determined by user communication devices in the communication network, and executes clustering on the plurality of user communication device groups.

Abstract: The invention relates a user communication device for cellular communication with a base station and D2D communication with at least one user communication device.

Abstract: A subset of mobile device candidates in a multi-input multi-output (MIMO) channel of network devices is selected for having a feedback priority among a set of mobile device candidates. The selection is based on a set of queue state information of a plurality of mobile device queues for transmitter and receiver devices of the MIMO channel in a multi-user MIMO network. A portion of the subset of mobile device candidates can be selected by a scheduling component of the system. Communications on the MIMO channels can be scheduled to the portion of the subset of mobile device candidates based on the feedback comprising channel state information and on the queue state information of the plurality of mobile device queues.
