Poro-viscoelastic effects during biomechanical testing of human brain tissue
(2021-08-17)
Article
Open AccessBrain tissue is one of the softest tissues in the human body and the quantification of its mechanical properties has challenged scientists over the past decades. Associated experimental results in the literature have been ... -
Permutation entropy analysis of the output of a laser diode under stimulated Brillouin scattering optical feedback
(2021-08-16)
Article
Open AccessThe chaotic output emitted by a diode laser with optical feedback has fascinated the community for decades. The external cavity delay time imparts a weak level of periodicity to the laser output (the so-called "time delay ... -
Evaluating temporal correlations in time series using permutation entropy, ordinal probabilities and machine learning
(2021-08)
Article
Open AccessTime series analysis comprises a wide repertoire of methods for extracting information from data sets. Despite great advances in time series analysis, identifying and quantifying the strength of nonlinear temporal correlations ... -
Discriminating chaotic and stochastic time series using permutation entropy and artificial neural networks
(Nature, 2021-08-04)
Article
Open AccessExtracting relevant properties of empirical signals generated by nonlinear, stochastic, and high-dimensional systems is a challenge of complex systems research. Open questions are how to differentiate chaotic signals from ... -
Experimental study of historical processing of cobalt arsenide ore for colouring glazes (15-16th century Europe)
(Elsevier Ltd, 2021-04-01)
Article
Restricted access - publisher's policyCobalt was used since the early antiquity to tinge glass and glazes in blue. The presence of arsenic in blue decorated glazes since ~1500 onwards and absence beforehand, observed in Europe, might be related to the processing ... -
Retrieving linear and nonlinear optical dispersions of matter: combined experiment-numerical ellipsometry in silicon, gold and indium tin oxide
(2021-09-17)
Article
Open AccessWe have presented a combined experimental and numerical method that can be used to predict complex nonlinear dispersion curves in almost any material, based exclusively on the experimental determination of harmonic generation ... -
Triangular Gross-Pitaevskii breathers and Damski-Chandrasekhar shock waves
(2021-01-01)
Article
Open AccessThe recently proposed map [arXiv:2011.01415] between the hydrodynamic equations governing the two-dimensional triangular cold-bosonic breathers [Phys. Rev. X 9, 021035 (2019)] and the high-density zero-temperature triangular ... -
Inverse-design of non-Hermitian potentials for on-demand asymmetric reflectivity
(2021-05-24)
Article
Open AccessWe propose a genetic algorithm-assisted inverse design approach to achieve ‘ondemand’ light transport in periodic and non-periodic planar structures containing dielectric and gain-loss layers. The optimization algorithm ... -
Rainfall regime trends at annual and monthly scales in Catalonia (NE Spain) and indications of CO2 emissions effects
(2021-09-16)
Article
Open AccessThe pluviometric regime in the Western Mediterranean and concretely in Catalonia (NE Spain) is characterised by irregular amounts at monthly and annual scales, sometimes with copious short episodes causing foods and, ... -
