Self-Organized Criticality and Thermodynamic Formalism [PDF]
Journal of Statistical Physics, 2004 We introduce a dissipative version of the Zhang's model of Self-Organized Criticality, where a parameter allows to tune the local energy dissipation. We analyze the main dynamical features of the model and relate in particular the Lyapunov spectrum with the transport properties in the stationary regime.

Engineering self-organized criticality in living cells. [PDF]
Nat Commun, 2021 Complex dynamical fluctuations, from intracellular noise, brain dynamics or computer traffic display bursting dynamics consistent with a critical state between order and disorder. Living close to the critical point has adaptive advantages and it has been

A Language as a Self-organized Critical System [PDF]
Complexity, 2017 A natural language (represented by texts generated by native speakers) is considered as a complex system, and the type thereof to which natural languages belong is ascertained. Namely, the authors hypothesize that a language is a self-organized critical system and that the texts of a language are “avalanches” flowing down its word cooccurrence graph ...

Avalanches and Self-Organized Criticality in superconductors [PDF]
The European Physical Journal B - Condensed Matter and Complex Systems, 2006 We review the use of superconductors as a playground for the experimental study of front roughening and avalanches. Using the magneto-optical technique, the spatial distribution of the vortex density in the sample is monitored as a function of time. The roughness and growth exponents corresponding to the vortex landscape are determined and compared to ...

From Self-Organized to Extended Criticality [PDF]
Frontiers in Physiology, 2012 We address the issue of criticality that is attracting the attention of an increasing number of neurophysiologists. Our main purpose is to establish the specific nature of some dynamical processes that although physically different, are usually termed as "critical," and we focus on those characterized by the cooperative interaction of many units.

Self‐organized criticality and urban development [PDF]
Discrete Dynamics in Nature and Society, 1999 Urban society is undergoing as profound a spatial transformation as that associated with the emergence of the industrial city two centuries ago. To describe and measure this transition, we introduce a new theory based on the concept that large‐scale, complex systems composed of many interacting elements, show a surprising degree of resilience to ...

Critical Self-Organization of Astrophysical Shocks [PDF]
The Astrophysical Journal, 2000 There are two distinct regimes of the first order Fermi acceleration at shocks. The first is a linear (test particle) regime in which most of the shock energy goes into thermal and bulk motion of the plasma. The second is an efficient regime when it goes into accelerated particles.

Modelling the outer radiation belt as a complex system in a self-organised critical state [PDF]
, 2005 The dynamic behaviour of the outer electron radiation belt makes this area of geo-space a candidate for the concept of self-organized criticality. It is shown here that frequency distributions of measured outer electron radiation belt data are well ...
