A broadcast method and system for continuously and opportunistically driving an optimal broadcast schedule based on most recent client demand feedback from a distributed set of broadcast clients. Therefore, a transistor is only requested to have responsibility with respect to a frequency of a base band component, but not to the carrier frequency. Each of the ferroelectric memory cells includes first and second gates for connecting the ferroelectric memory cell to the read line and the write line, respectively, in response to signals on the ferroelectric memory cell select bus corresponding to that ferroelectric memory cell. The method then identifies a plurality of search assistance technologies based on the user’s search self-efficacy and frustration. In another aspect, the invention provides diagnostic methods.
