Abstract: The present disclosure relates to computer-implemented systems and methods for facilitating simultaneous poll responses. A method may include assigning respective subsets of subcarrier frequencies to a plurality of user devices for communication over a wireless channel. The method may also include transmitting, simultaneously, a channel status request poll to the user devices. Additionally, the method may include determining, based at least in part on a first channel status response received via a first subset of subcarrier frequencies over the wireless channel, that the first channel status response is received from the first user device. Similarly, the method may also include determining a second channel status response is received from a second user device. Furthermore, the method may include determining, based at least in part on the first channel status response and the second channel status response, to schedule simultaneous data communication for the first device and the second device.

Abstract: A transparent electrode and method for manufacturing the same are disclosed. The major integrants of the transparent electrode comprise a graphene and a nanofiber. The nanofiber exhibits a light-permeable network structure to increase the light transmittance of the transparent electrode. The graphene is absorbed on the surface of the nanofiber to form a conductive light-permeable network structure. And the unique properties of the graphene lead an improvement of the mechanical strength property of the transparent electrode.
