CRITICAL SCALING AND TYPE-III INTERMITTENT CHAOS IN ISOLATED RABBIT RESISTANCE ARTERIES

We have shown that spontaneous oscillations in flow in rabbit ear resistance arteries may sometimes exhibit behavior typical of type-III Pomeau-Manneville intermittency. The average number of oscillations per laminar length ⟨n⟩ was related to a bifurcation parameter ɛ according to power-law scaling of the form ⟨n⟩∼ɛ −β . The critical exponent β was estimated as ∼0.80, which is within the range reported for type-III intermittent chaos in nonbiological systems.
