Overcancel

Note that there can still be feedback, however, if the gain is so high as to "overcancel" the input signal with the higher level output.

Don't overcancel our FDCs. Don't obliterate with felt-tipped markers.

The self-diffusivities of a rod, in general, decrease with the concentration because of the rod entanglement and hydrodynamic interaction, but the excluded volume effect in the polarized scattering largely cancels (and sometimes overcancels) the decrease.
