Baptista, Dariel M. Maranhao, and J. C. Sartorelli<br/> We show a function that fits well the probability density of return times between two consecutive visits of a chaotic trajectory to finite size regions in phase space. It deviates from the exponential statistics by a small power-law term, a term that represents the deterministic manifestation of the ... [Chaos 19, 043115 (2009)] published Fri Nov 20, 2009. Unpinning of a spiral wave anchored around a circular obstacle by an external wave train: Common aspects of a chemical reaction and cardiomyocyte tissue http://link.aip.org/link/?CHA/19/043114/1&agg=rss Masanobu Tanaka, Akihiro Isomura, Marcel Horning, Hiroyuki Kitahata, Konstantin Agladze et al.<br/> It is well known that spiral waves are often stabilized by anchoring to a local heterogeneity (pinning) and that such pinned waves are rather difficult to eliminate. In the present report, we show that pinned spiral waves can be eliminated through collision with a wave train arriving from the outer ... [Chaos 19, 043114 (2009)] published Thu Nov 19, 2009. Synchronization in coupled time-delayed systems with parameter mismatch and noise perturbation http://link.aip.org/link/?CHA/19/043113/1&agg=rss Yongzheng Sun and Jiong Ruan<br/> In this paper, a design of coupling and effective sufficient condition for stable complete synchronization and antisynchronization of a class of coupled time-delayed systems with parameter mismatch and noise perturbation are established. Based on the LaSalle-type invariance principle for stochastic ... [Chaos 19, 043113 (2009)] published Wed Nov 11, 2009. Chaoticity of the blood cell production system http://link.aip.org/link/?CHA/19/043112/1&agg=rss Ryszard Rudnicki<br/> We present a structured model of stem cells given by a partial differential equation. This equation generates a semiflow acting on the set of densities. We show that this semiflow possesses an invariant exact measure positive on open sets. From this it follows that the system is chaotic, i.e., it ha ... [Chaos 19, 043112 (2009)] published Fri Nov 6, 2009.

Bifurcation and chaos in spin-valve pillars in a periodic applied magnetic field http://link.aip.org/link/?CHA/19/043111/1&agg=rss S. Murugesh and M. Lakshmanan<br/> We study the bifurcation and chaos scenario of the macromagnetization vector in a homogeneous nanoscale-ferromagnetic thin film of the type used in spin-valve pillars. The underlying dynamics is described by a generalized LandauLifshitzGilbert (LLG) equation. The LLG equation has an especially appea ... [Chaos 19, 043111 (2009)] published Tue Nov 3, 2009. Accurate noise projection for reduced stochastic epidemic models http://link.aip.org/link/?CHA/19/043110/1&agg=rss Eric Forgoston, Lora Billings, and Ira B. Schwartz<br/> We consider a stochastic susceptible-exposed-infected-recovered (SEIR) epidemiological model. Through the use of a normal form coordinate transform, we are able to analytically derive the stochastic center manifold along with the associated, reduced set of stochastic evolution equations.
