[HTML][HTML] Persistence in complex systems
Persistence is an important characteristic of many complex systems in nature, related to how
long the system remains at a certain state before changing to a different one. The study of …

[LIBRO][B] Fractal patterns in nonlinear dynamics and applications
Most books on fractals focus on deterministic fractals as the impact of incorporating
randomness and time is almost absent. Further, most review fractals without explaining what …

Natural time analysis of critical phenomena
A quantity exists by which one can identify the approach of a dynamical system to the state
of criticality, which is hard to identify otherwise. This quantity is the variance of natural time χ …

Seismic Electric Signals: An additional fact showing their physical interconnection with seismicity
Natural time analysis reveals novel dynamical features hidden behind time series in
complex systems. By applying it to the time series of earthquakes, we find that the order …

Seismic electric signals (SES) and earthquakes: A review of an updated VAN method and competing hypotheses for SES generation and earthquake triggering
DS Helman - Physics of the Earth and Planetary Interiors, 2020 - Elsevier
Electromagnetic phenomena are sometimes associated with seismic events, but earthquake
prediction using seismic electric signals (SES) has not been seriously considered since the …

Study of the temporal correlations in the magnitude time series before major earthquakes in Japan
A characteristic change of seismicity has been recently uncovered when the precursory
Seismic Electric Signals activities initiate before an earthquake occurrence. In particular, the …

Scale-specific order parameter fluctuations of seismicity in natural time before mainshocks
We have previously shown that the probability distribution of the order parameter κ 1 of
seismicity in natural time turns to be bimodal when approaching a mainshock. This reflects …

On the progress of the 2015–2016 El Niño event
It has been recently reported that the current 2015–2016 El Niño could become “one of the
strongest on record”. To further explore this claim, we performed the new analysis described …
