Investigation of the Regularities of the Influence of Meteorological Factors on Avalanches in Eastern Kazakhstan

Atmosphere
This paper studies the influence of meteorological factors on avalanche occurrence in East Kazakhstan using modern data analysis methods. A dataset of 111 avalanche events in nine avalanche-prone areas of the region, recorded between 2012 and 2023, was ...

Deterministically Driven Avalanche Models of Solar Flares

, 2014
We develop and discuss the properties of a new class of lattice-based avalanche models of solar flares. These models are readily amenable to a relatively unambiguous physical interpretation in terms of slow twisting of a coronal loop.

Avalanche dynamics for active matter in heterogeneous media

New Journal of Physics, 2018
Using numerical simulations, we examine the dynamics of run-and-tumble disks moving in a disordered array of fixed obstacles. As a function of increasing active disk density and activity, we find a transition from a completely clogged state to a ...

Self-organization without conservation: Are neuronal avalanches generically critical?

, 2010
Recent experiments on cortical neural networks have revealed the existence of well-defined avalanches of electrical activity. Such avalanches have been claimed to be generically scale-invariant -- i.e.

Prediction of avalanches on the basis of the 27‐day Solar activity variations

Лëд и снег, 2015
Many natural processes on the Earth are the cyclic ones and they are self-sustaining within a system of the Sun–Earth relations. To verify our hypothesis on a cyclic occurrence of the avalanche processes and to estimate a possibility to predict ...

Self - organized - criticality and synchronization in pulse coupled relaxation oscillator systems: the Olami, Feder and Christensen model and the Feder and Feder model

, 1996
We reexamine the dynamics of the Olami, Feder and Christensen (OFC) model. We show that, depending on the dissipation, it exhibits two different behaviors and that it can or cannot show self - organized - criticality (SOC) and/or synchronization. We also

Statistical evaluation of waveform collapse reveals scale-free properties of neuronal avalanches

Frontiers in Computational Neuroscience, 2016
Neural avalanches are a prominent form of brain activity characterized by network-wide bursts whose statistics follow a power-law distribution with a slope near 3/2.

Nowcasting Avalanches as Earthquakes and the Predictability of Strong Avalanches in the Olami-Feder-Christensen Model

Entropy, 2020
Nowcasting earthquakes, suggested recently as a method to estimate the state of a fault and hence the seismic risk, is based on the concept of natural time.

Local and global avalanches in a 2D sheared granular medium

, 2017
We present the experimental and numerical studies of a 2D sheared amorphous material constituted of bidisperse photo-elastic disks. We analyze the statistics of avalanches during shear including the local and global fluctuations in energy and changes in ...

Comments on avalanche flow models based on the concept of random kinetic energy

Journal of Glaciology, 2018
In a series of papers, Bartelt and co-workers developed novel snow-avalanche models in which random kinetic energy (RKE) RK (a.k.a. granular temperature) is a key concept.
