Cortical networks exhibit diverse patters of spontaneous neural activity, including oscillations, synchrony and waves. The spontaneous activity often in addition exhibits slow alternations between high activity periods, or bursts, followed by essentially quiet periods. Bursts can last from a few to several hundreds of milliseconds and, if analysed at a finer temporal scale, show a complex struc...

This study examine the difference in the size of avalanches among industries triggered by demand shocks, which can be rephrased by control of the economy or fiscal policy, and by using the production-inventory model and observed data. We obtain the following results. (1) The size of avalanches follows power law. (2) The mean sizes of avalanches for industries are diverse but their standard devi...

Seismic signals generated by artificially released avalanches were studied f’rom the seismological viewpoint in the time and frequency domains in an attempt to characterise them for monitoring purposes. The avalanches were artificially released and the corresponding seismic signals were recorded at different sites within a radius of up to 3 km together with the video images with a common time r...

As shown recently (arXiv:0801.3056), several types of neuronal complex networks involving nonlinear integration-and-fire dynamics exhibit an abrupt activation along their transient regime. Interestingly, such an avalanche of activation has also been found to depend strongly on the topology of the networks: while the Erdős-Rény, Barabási-Albert, path-regular and path-transformed BA models exhibi...

Ongoing cortical activity consists of sequences of synchronized bursts, named neuronal avalanches, whose size and duration are power law distributed. These features have been observed in a variety of systems and conditions, at all spatial scales, supporting scale invariance, universality and therefore criticality. However, the mechanisms leading to burst triggering, as well as the relationship ...

The freeze-thaw (F-T) induced deterioration in rocks affects their durability, leading to various landslides, rockslides, and avalanches. study focuses on estimating loss rock strength using mineralogical properties under the influence of multiple FT cycles. samples were collected from F-T affected north Indian Himalayan region. specimens subjected conditioning (0th, 10th, 20th 30th cycles). (s...

ABSTRACT: Sandpile and avalanche models of failure were introduced recently (Bak et al., 1987, and an avalanche of publications with references to this paper) to simulate processes of different nature (earthquakes, charge density waves, forest fires, etc., including economics) characterized by self-organized critical behavior. Statistical properties of an important class of these models, Abelia...
