Signatures of criticality in turning avalanches of schooling fish

Physical Review Research
Moving animal groups transmit information through propagating waves or behavioral cascades, exhibiting characteristics akin to systems near a critical point from statistical physics. Using data from freely swimming schooling fish in an experimental tank,

Omori Law after Large-Scale Destruction of Production Network [PDF]

Progress of Theoretical Physics Supplement, 2012
After the two giant earthquakes, Kobe 1995 and East Japan 2011, a large-scale destruction took place on supplier-customer network. These primary and exogenous shocks were propagated on the production network, which caused a secondary effect resulting in chained bankruptcies.

Unified scaling law for earthquakes

, 2002
We propose and verify a unified scaling law that provides a framework for viewing the probability of the occurrence of earthquakes in a given region and for a given cutoff magnitude.

Non-Markovian nature of cryptocurrencies

Frontiers in Physics
Whether financial assets movements exhibit correlation and memory has been an intriguing question for physicists. This study aims to investigate whether financial shocks exhibit non-Markovian behavior. In particular, it explores the presence of long-term

Correlated earthquakes in a self-organized model [PDF]

Nonlinear Processes in Geophysics, 2009
Motivated by the fact that empirical time series of earthquakes exhibit long-range correlations in space and time and the Gutenberg-Richter distribution of magnitudes, we propose a simple fault model that can account for these types of scale-invariance ...

A Global-scale Database of Seismic Phases from Cloud-based Picking at Petabyte Scale

Seismica
We present the first global-scale database of 4.3 billion P- and S-wave picks extracted from 1.3 PB continuous seismic data via a cloud-native workflow.

Omori’s Law in the Occurrence of Solar Flare : Approach of Hybrid Model

Iranian Journal of Astronomy and Astrophysics, 2020
Solar flares are large-scale phenomena that have a significant effect on theEarth’s climate. Using the solar flare time series from January 1, 2006 to July 21, 2016,we develop a complex network for predicting solar flares. In the work, hybrid modelis employed to construct complex network.

On the Omori-Yau almost maximum principle

, 2019
We introduce a new sufficient condition for the conclusion of the Omori-Yau almost maximum principle in terms of the existence of a special exhaustion function. This seems presenting perhaps the easiest proof.

Complex networks of earthquakes and aftershocks [PDF]

Nonlinear Processes in Geophysics, 2005
We invoke a metric to quantify the correlation between any two earthquakes. This provides a simple and straightforward alternative to using space-time windows to detect aftershock sequences and obviates the need to distinguish main shocks from ...
