    摘要: An example embodiment may involve receiving, at a node of a radio access network, input signals on a plurality of wireless channels, wherein uplink channels in the plurality of wireless channels are respectively associated with downlink channels in the plurality of wireless channels; determining uplink characteristics for the uplink channels; providing, to a trained neural network, the uplink characteristics, wherein the trained neural network was iteratively trained, with a training data set of recorded uplink characteristics and recorded downlink characteristics, to form predictions of the recorded downlink characteristics from the recorded uplink characteristics, wherein the trained neural network includes an encoder that maps the recorded uplink characteristics to latent vector representations, and a decoder that maps the latent vector representations to the predictions; receiving, from the trained neural network, a prediction of downlink characteristics for the downlink channels; and transmitting, on the downlink channels, output signals based on the prediction.

    摘要: A method of spontaneously patterning a polymer during frontal polymerization includes activating an initiation region of a monomer solution to initiate a polymerization reaction. A polymerization front is generated and propagates through the monomer solution in a radial or longitudinal direction away from the initiation region. The monomer solution is spontaneously heated downstream of the polymerization front by thermal transport away from the polymerization reaction. Once a localized region of the monomer solution reaches a temperature sufficient for spontaneous initiation of another polymerization reaction, a new polymerization front is generated and propagates through the monomer solution in a circumferential or transverse direction. The spontaneous heating of the monomer solution downstream of the polymerization front and the initiation of another polymerization reaction occurs cyclically, producing multiple new polymerization fronts and spatial variations in reaction temperature across the monomer solution. Once polymerization is complete, a spontaneously patterned polymer is formed.
