will give higher priority to forcing self-polarization as indicated in the logic below. This is consistent with the overall philoso-
phy of distance memory polarization.
The memory polarization cannot be applied permanently but for a limited time only; the self-polarization may be
applied permanently and therefore should take higher priority.
