QUANTIFICATION OF ECONOMIC AND SOCIAL RISKS OF DEBRIS FLOWS FOR THE BLACK SEA COASTAL REGION OF THE NORTH CAUCASUS

open access: yesGeography, Environment, Sustainability, 2014
Debris flows are the most frequent and disastrous natural hazards among other exogenic processes at the Black Sea coastal region of the North Caucasus. Numerous debris flow releases are reported every year between Novorossiysk and Krasnaya Polyana.

Neuronal avalanches differ from wakefulness to deep sleep - evidence from intracranial depth recordings in humans [PDF]

open access: yes, 2013
Neuronal activity differs between wakefulness and sleep states. In contrast, an attractor state, called self-organized critical (SOC), was proposed to govern brain dynamics because it allows for optimal information coding.

Fuzzy modelling of powder snow avalanches [PDF]

open access: yes, 2004
This paper examines powder snow avalanches by introducing a predetermined degree of variation, or fuzziness, in model parameters. Given a value of vagueness in the parameters, fuzzy set theory makes it possible to evaluate the vagueness in the results ...

Scaling in the Local Strain-Rate Field during Jerky Flow in an Al-3%Mg Alloy

open access: yesMetals, 2020
Jerky flow in alloys, or the Portevin-Le Chatelier effect, presents an outstanding example of self-organization phenomena in plasticity. Recent acoustic emission investigations revealed that its microscopic dynamics is governed by scale invariance ...

Can model-based avalanche forecasts match the discriminatory skill of human danger-level forecasts? A comparison from Switzerland [PDF]

open access: yesNatural Hazards and Earth System Sciences
In recent years, physics-based snowpack models combined with machine-learning techniques have gained momentum in public avalanche forecasting. When integrated with spatial interpolation methods, these approaches enable fully model-driven predictions of ...

Neuronal avalanches recorded in the awake and sleeping monkey do not show a power law but can be reproduced by a self-organized critical model [PDF]

open access: yes, 2009
Poster presentation: Self-organized critical (SOC) systems are complex dynamical systems that may express cascades of events, called avalanches [1].

Size Distribution of Emitted Energies in Local Load Sharing Fiber Bundles

open access: yesFrontiers in Physics, 2021
We study the local load sharing fiber bundle model and its energy burst statistics. While it is known that the avalanche size distribution of the model is exponential, we numerically show here that the avalanche size (s) and the corresponding average ...

Feedback Mechanisms for Self-Organization to the Edge of a Phase Transition

open access: yesFrontiers in Physics, 2020
Scale-free outbursts of activity are commonly observed in physical, geological, and biological systems. The idea of self-organized criticality (SOC), introduced back in 1987 by Bak, Tang, and Wiesenfeld suggests that, under certain circumstances, natural
