Query: Stochastic resonance in bistable confining potentials. On the role of
  confinement   We study the effects of the confining conditions on the occurrence of
stochastic resonance (SR) in continuous bistable systems. We model such systems
by means of double-well potentials that diverge like the q-th power of |x| when
|x| goes to infinite. For super-harmonic (hard) potentials with q > 2 the SR
peak sharpens with increasing q, whereas for sub-harmonic (soft) potentials, q
< 2, it gets suppressed.
