Rock avalanches clusters along the northern Chile coastal scarp
(Elsevier, 2017)
Rock avalanche clusters can be relevant indicators of the evolution of specific regions. They can be used to define: the type and intensity of triggering events, their recurrence and potential probability of occurrence, ...
Avalanches in Critical Activated Random Walks
(Birkhäuser, 2021)
We consider Activated Random Walks on ℤ with totally asymmetric jumps and critical particle density, with different time scales for the progressive release of particles and the dissipation dynamics. We show that the ...
Avalanche-size distributions in mean-field plastic yielding models
(American Physical Society, 2015-10-15)
We discuss the size distribution N(S) of avalanches occurring at the yielding transition of mean-field (i.e., Hebraud-Lequeux) models of amorphous solids. The size distribution follows a power law dependence of the form ...
Driving rate dependence of avalanche statistics and shapes at the yielding transition
(American Physical Society, 2016-02)
We study stress time series caused by plastic avalanches in athermally sheared disordered materials. Using particle-based simulations and a mesoscopic elastoplastic model, we analyze system size and shear-rate dependence ...
The Plata rock avalanche: deciphering the occurrence of this huge collapse in a glacial valley of the Central Andes (33º S)
(Frontiers Media, 2020-07)
This paper reviews the genesis of a chaotic deposit in the Blanco River basin (BRB) in the Argentine Andes that has been interpreted to be either of debris flow or glacial origin. A detailed sedimentological and geomorphic ...
Undersampled Critical Branching Processes on Small-World and Random Networks Fail to Reproduce the Statistics of Spike Avalanches
(2014-04-21)
The power-law size distributions obtained experimentally for neuronal avalanches are an important evidence of criticality in
the brain. This evidence is supported by the fact that a critical branching process exhibits the ...
Imageamento magneto-ótico quantitativo em filmes finos supercondutores bicamada e com gradiente nanométrico de espessura
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-12-11)
Vortex matter in superconductors has been the focus of research of both theoretical and experimental groups around the world.
When developing superconducting devices patterned on thin films one should bear in mind that ...
Complete Blow-up and Avalanche Formation for a Parabolic System with Non-Simultaneous Blow-up
(De Gruyter, 2010-08)
We study the possibility of defining a nontrivial continuation after the blow-up time for a system of two heat equations with a nonlinear coupling at the boundary. It turns out that any possible continuation that verify a ...
Distribution of velocities in an avalanche, and related quantities: Theory and numerical verification
(IOP Publishing, 2019-09-11)
We study several probability distributions relevant to the avalanche dynamics of elastic interfaces driven on a random substrate: The distribution of size, duration, lateral extension or area, as well as velocities. Results ...
Avalanches in tip-driven interfaces in random media
(Europhysics Letters, 2016-01-25)
We analyse by numerical simulations and scaling arguments the avalanche statistics of 1-dimensional elastic interfaces in random media driven at a single point. Both global and local avalanche sizes are power-law distributed, ...
