Bonabeau hierarchy models revisited
Lucas Lacasa, Bartolo Luque
What basic processes generate hierarchy in a collective? The Bonabeau model provides us a simple mechanism based on randomness which develops self-organization through both winner/…
Conical emission, pulse splitting and X-wave parametric amplification in nonlinear dynamics of ultrashort light pulses
Daniele Faccio, Miguel A. Porras, Audrius Dubietis +3
The precise observation of the angle-frequency spectrum of light filaments in water reveals a scenario incompatible with current models of conical emission (CE). Its description in…
Non-stationary Rayleigh-Taylor instability in supernovae ejecta
Xavier Ribeyre, Ludovic Hallo, Vladimir Tikhonchuk +2
The Rayleigh-Taylor instability plays an important role in the dynamics of several astronomical objects, in particular, in supernovae (SN) evolution. In this paper we develop an an…
Accurate and robust image superresolution by neural processing of local image representations
Carlos Miravet, Francisco B. Rodriguez
Image superresolution involves the processing of an image sequence to generate a still image with higher resolution. Classical approaches, such as bayesian MAP methods, require ite…
Adaptive Aperture Defocused Digital Speckle Photography
Jose M. Diazdelacruz
Speckle photography can be used to monitor deformations of solid surfaces. The measuring characteristics, such as range or lateral resolution depend heavily on the optical recordin…
On the exposure to mobile phone radiation in trains
J. Ferrer, L. Fernandez-Seivane, J. M. Hernando +3
This report presents theoretical estimates of the Power Density levels which may be reached inside trains. Two possible sources of high levels of radiation are discussed. The first…
Wavelet Time Shift Properties Integration with Support Vector Machines
Jaime Gomez, Ignacio Melgar, Juan Seijas
This paper presents a short evaluation about the integration of information derived from wavelet non-linear-time-invariant (non-LTI) projection properties using Support Vector Mach…
Point set stratification and Delaunay depth
Manuel Abellanas, Mercè Claverol, Ferran Hurtado
In the study of depth functions it is important to decide whether we want such a function to be sensitive to multimodality or not. In this paper we analyze the Delaunay depth funct…
Spectroscopic evidence for polarons in partially occupied spin-orbit states of YBa2Cu3O7
J. V. Acrivos, L. Nguyen, H. S. Sahibudeen +2
The spin-orbit split white line, synchrotron X-ray spectra at the respective Cu and Ba L2,3 and Ba M4,5 edges in YBa2Cu3O7 crystal, powders, films and derivatives are compared to t…
Reduction of wood hygroscopicity and associated dimensional response by repeated humidity cycles
Luis García Esteban, Joseph Gril, Paloma De Palacios De Palacios +1
The reduction of wood response to variations of ambient humidity, described as kind of ageing, has been studied from both points of view of moisture uptake and dimensional changes.…
Comment on Singularity-free Cosmological Solutions with Non-rotating Perfect Fluids
L. Fernandez-Jambrina
A conjecture stated by Raychaudhuri which claims that the only physical perfect fluid non-rotating non-singular cosmological models are comprised in the Ruiz-Senovilla and Fernande…
Noise in Spectral Fluctuations of Quantum Systems
J. M. G. Gomez, A. Relano, J. Retamosa +4
The power law in the power spectrum characterizes the fluctuating observables of many complex natural systems. Considering the energy levels of a quantum system as a discre…
Anomalous optical absorption in a random system with scale-free disorder
E. Diaz, A. Rodriguez, F. Dominguez-Adame +1
We report on an anomalous behavior of the absorption spectrum in a one-dimensional lattice with long-range-correlated diagonal disorder with a power-like spectrum in the form S(k)…
Bulk viscous FWR with time varying constants revisited
J. A. Belinchón
We study a full causal bulk viscous cosmological model with flat FRW symmetries and where the ``constants'' and vary. We take into account the possible effects of a v…
