The hypothesis of self-organized criticality explains the existence of long-range ‘space-time’ correlations, observed inseparably in many natural dynamical systems. A simple link between these correlations is yet unclear, particularly in fluctuations at ‘external drive’ time scales. As an example, we consider a class of sandpile models displaying non-trivial correlations. Employing the scaling methods, we demonstrate the computation of spatial correlation by establishing a link between local…

Energy fluctuations in one dimensional Zhang sandpile model
We consider the Zhang sandpile model in one-dimension (1D) with locally conservative (or dissipative) dynamics and examine its total energy fluctuations at the external drive time scale. The


Two-state model of self-organized criticality
Studies a two-state version of the sandpile model of self-organized criticality. Instead of a critical height of stability as in the sandpile model, the author introduces a hard core repulsion among
25 Years of Self-organized Criticality: Concepts and Controversies
Introduced by the late Per Bak and his colleagues, self-organized criticality (SOC) has been one of the most stimulating concepts to come out of statistical mechanics and condensed matter theory in
Avalanche dynamics in a pile of rice
THE idea of self-organized criticality1(SOC) is commonly illustrated conceptually with avalanches in a pile of sand grains. The grains are dropped onto a pile one by one, and the pile ultimately
Universal spectral features of different classes of random-diffusivity processes
Stochastic models based on random diffusivities, such as the diffusing-diffusivity approach, are popular concepts for the description of non-Gaussian diffusion in heterogeneous media. Studies of
“1/fα noise” is equivalent to an eigenstructure power relation
The discovery that the power spectrum of a time series of observations has a 1/fα character has been thought to imply that the generating process has some hidden, remarkable, nature, such as
Crackling noise
Results are illustrated by using results for the model of crackling noise in magnets, the use of the renormalization group and scaling collapses are explained, and some continuing challenges in this still-evolving field are highlighted.
Memoryless nonlinear response: A simple mechanism for the 1/f noise
Discovering the mechanism underlying the ubiquity of “ ” noise has been a long-standing problem. The wide range of systems in which the fluctuations show the implied long-time correlations suggests
How nature works: The science of self-organized criticality
His ruthless simplifications of geology, evolution, and neurology pay off because his models describe behavior that is common across these domains, and this universality means that trampling across others turf is not only acceptable, but almost mandatory, if the underlying principles are to be exposed.
Low-frequency 1/f noise in graphene devices.
The characteristic features of 1/f noise in graphene and few-layer graphene are reviewed, and the implications of such noise for the development of graphene-based electronics including high-frequency devices and sensors are examined.
Apesar da gestão de carreiras ser uma preocupação recente no quadro da gestão das relações de trabalho, é hoje evidente a crise em que se encontra a forma tradicional de abordagem desta problemática.
