Abstract
⺠Motifs with a positive feedback in a three-node negative feedback loop studied. ⺠A fixed point and a limit cycle can stably coexist in a certain parameter region. ⺠At the bifurcation point the period of the oscillations diverges. ⺠Intrinsic noise causes switching between oscillatory state and stationary state. ⺠Switching occurs in circadian clock models with positive and negative feedbacks.
