Spatial variability of the snow depth on mountain slope in Svalbard

Лëд и снег, 2018
The study was carried out to estimate the spatial variability of snow cover depths in avalanche centers of the mountain slopes of Svalbard. Accounting for the variability is necessary for monitoring the snow cover depths in the avalanche centers and ...

Neuronal Avalanches Across the Rat Somatosensory Barrel Cortex and the Effect of Single Whisker Stimulation

Frontiers in Systems Neuroscience, 2021
Since its first experimental signatures, the so called “critical brain hypothesis” has been extensively studied. Yet, its actual foundations remain elusive.

AVALANCHE

, 2022
Annotation: this article covers the types of rams, their classifications and what to do if they are left in the whirlpool of landslides, how to protect from them, as an unfortunate coincidence.

Particle-hole symmetry in a sandpile model

, 2005
In a sandpile model addition of a hole is defined as the removal of a grain from the sandpile. We show that hole avalanches can be defined very similar to particle avalanches.

Slip avalanches in a fiber bundle model [PDF]

, 2010
We study slip avalanches in disordered materials under an increasing external load in the framework of a fiber bundle model. Over-stressed fibers of the model do not break, instead they relax in a stick-slip event which may trigger an entire slip ...

Size of flux jumps in superconducting films [PDF]

, 2005
Magneto-optical imaging is used to visualize vortex avalanches in MgB2 films at 4K. Avalanches ranging from 50 to 50000 vortices were detected. The size distribution function has a clear peak whose position moves towards larger sizes as the applied field

AVALANCHES - EXTREME WINTER EVENTS. MONITORING AND AVALANCHE RISK [PDF]

Aerul şi Apa: Componente ale Mediului, 2012
This paper presents the avalanches monitored by the National Meteorological Administration within the nivo-meteorological program since february 2004. Daily observations and weekly snow measurements are made at the weather stations from Bucegi Mountains -

Evolution of locally excited avalanches in semiconductors

, 2010
We show that semiconductor avalanche photodiodes can exhibit diminutive amplification noise during the early evolution of avalanches. The noise is so low that the number of locally excited charges that seed each avalanche can be resolved.

Probabilistic size effect law for mode II fracture from critical lengths in snow slab avalanche weak layers

Journal of Glaciology, 2019
From field observations, dry snow slab avalanche initiation is associated with fracture within relatively thin weak layers under stronger, cohesive slabs.

A Heavenly Example of Scale Free Networks and Self-Organized Criticality

, 2003
The sun provides an explosive, heavenly example of self-organized criticality. Sudden bursts of intense radiation emanate from rapid rearrangements of the magnetic field network in the corona.
