The present invention relates to certain tri-substituted phenyl derivatives and analogues of formula, to a process for preparing such compounds, having the utility in clinical conditions associated with insulin resistance, to methods for their therapeutic use and to pharmaceutical compositions containing them. The packet at the head of one queue is transmitted, and no other packet is transmitted until a transmit complete signal is generated. The transistor biasing circuit provides two functions. The parameters for cells to be programmed can include, for example, cell address locations for the cells to be programmed, the number of cells to be programmed, andor other desired parameters associated with the cells to be programmed.
