The dynamics of hybrid metabolic-genetic oscillators

Ed Reznik, Tasso J. Kaper, and Daniel Segrè

The synthetic construction of intracellular circuits is frequently hindered by a poor knowledge of appropriate kinetics and precise rate parameters. Here, we use generalized modeling (GM) to study the dynamical behavior of topological models of a family of hybrid metabolic-genetic circuits known as “metabolators.”

Hierarchical networks, power laws, and neuronal avalanches

Eric J. Friedman and Adam S. Landsberg

We show that in networks with a hierarchical architecture, critical dynamical behaviors can emerge even when the underlying dynamical processes are not critical. This finding provides explicit insight into current studies of the brain's neuronal network showing power-law avalanches in neural recordings, and provides a theoretical justification of recent numerical findings.

Coupling and noise induced spiking-bursting transition in a parabolic bursting model

Lin Ji, Jia Zhang, Xiufeng Lang, and Xiuhui Zhang

The transition from tonic spiking to bursting is an important dynamic process that carry physiologically relevant information. In this work, coupling and noise induced spiking-bursting transition is investigated in a parabolic bursting model with specific discussion on their cooperation effects.

Robust global synchronization of two complex dynamical networks

Mohammad Mostafa Asheghan and Joaquín Míguez

We investigate the synchronization of two coupled complex dynamical networks, a problem that has been termed outer synchronization in the literature. Our approach relies on (a) a basic lemma on the eigendecomposition of matrices resulting from Kronecker products and (b) a suitable choice of Lyapunov function related to the synchronization error dynamics.

CrossMark Implemented on AIP journals

crossmarkAIP Publishing is dedicated to scientific accuracy and integrity and as a result has implemented CrossMark on its publications. As of December 2012, a CrossMark logo will appear on an HTML page or PDF file indicating that the publisher is maintaining the published document through any updates, corrections, enhancements, retractions, and other such changes. Clicking the CrossMark logo reveals status information about the document and tells readers whether they are accessing the most recent and reliable version or not. A link to any updated version will be included. You can learn more about CrossMark from the CrossRef website.


The 2012 Nobel Prize in Physics

Nobel Medal for Physics and Chemistry The American Institute of Physics congratulates this year's Nobel Laureates in Physics, Serge Haroche and David J. Wineland “for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems."

CHAOS ranks among the top ten journals in Applied Mathematics and Mathematical Physics.
