Query: Oscillating kinks in forced oscillatory media: A new type of instability   A new type of instability resulting in oscillatory propagating kinks is
presented. It is observed in periodically forced oscillatory media at 1:1
resonance, where phase kinks have close similarities to pulses in excitable
media. Considering the periodically forced complex Ginzburg-Landau equation,
examples for transitions involving oscillating kinks between different
dynamical regimes are described. The oscillatory instability is discussed
within the framework of a bifurcation analysis of the kink profiles
