Uncovering temporal regularity in atmospheric dynamics through Hilbert phase analysis
(Institute of Physics (IOP), 2019-05-03)
Article
Accés obertUncovering meaningful regularities in complex oscillatory signals is a challenging problem with applications across a wide range of disciplines.Here, we present a novel approach, based on the Hilbert transform (HT).We show ... -
Unravelling the community structure of the climate system by using lags and symbolic time-series analysis
(Macmillan Publishers, 2016-07-11)
Article
Accés obertMany natural systems can be represented by complex networks of dynamical units with modular structure in the form of communities of densely interconnected nodes. Unraveling this community structure from observed data ... -
Unsupervised feature extraction of anterior chamber OCT images for ordering and classification
(Nature, 2019-02-04)
Article
Accés obertWe propose an image processing method for ordering anterior chamber optical coherence tomography (OCT) images in a fully unsupervised manner. The method consists of three steps: Firstly we preprocess the images (filtering ... -
Unveiling temporal correlations characteristic to phase transition in the output intensity of a fiber laser
(2016-01-22)
Article
Accés obertWe use advanced statistical tools of time-series analysis to characterize the dynamical complexity of the transition to optical wave turbulence in a fiber laser. Ordinal analysis and the horizontal visibility graph applied ... -
Unveiling the complex organization of recurrent patterns in spiking dynamical systems
(MACMILLAN PUBLISHERS LIMITED, 2014-04-15)
Article
Accés obertComplex systems displaying recurrent spike patterns are ubiquitous in nature. Understanding the organization of these patterns is a challenging task. Here we study experimentally the spiking output of a semiconductor laser ...
