Query: Nonequilibrium Response and Frenesy   We present examples of how time-symmetric kinetic factors contribute to the
response either in nonlinear order around equilibrium or in linear order around
nonequilibrium. The phenomenology we associate to that so called frenetic
contribution are negative differential conductivity, changes in the Einstein
relation between friction and noise, and population inversion.
