    Very quick question:
    In the hybrid parameter model for BJTs, does HIC mean the resistance between the base and collector in a common collector amplifier?

    It is the input impedance of the transistor. And by virtue of:

    r_{in}\approx\betaR_{E}

    It corresponds to the emitter resistance.
