Clogging transition of vibrationdriven vehicles passing through constrictions
(201712)"We report experimental results on the competitive passage of elongated selfpropelled vehicles rushing through a constriction. For the chosen experimental conditions, we observe the emergence of intermittencies similar ... 
Simulating competitive egress of noncircular pedestrians
(201704)"We present a numerical framework to simulate pedestrian dynamics in highly competitive conditions by means of a forcebased model implemented with spherocylindrical particles instead of the traditional, symmetric disks. ... 
Model selection: Using information measures from ordinal symbolic analysis to select model subgridscale parameterizations
(2017)"The use of information measures for model selection in geophysical models with subgrid parameterizations is examined. Although the resolved dynamical equations of atmospheric or oceanic global numerical models are well ... 
Antistokes Raman gain enabled by modulation instability in midIR waveguides
(201811)"The inclusion of selfsteepening in the linear stability analysis of modulation instability (MI) leads to a power cutoff above which the MI gain vanishes. Under these conditions, MI in midIR waveguides is shown to give ... 
Characterization of autoregressive processes using entropic quantifiers
(201801)"The aim of the contribution is to introduce a novel information plane, the causalamplitude informational plane. As previous works seems to indicate, Bandt and Pompe methodology for estimating entropy does not allow to ... 
Infuence of bottleneck lengths and position on simulated pedestrian egress
(201701)"In this paper, the problem of pedestrian egress under di erent geometries is studied by means of two numerical models. The length of the bottleneck after the exit and the distance of the exit to the lateral wall of a ... 
Active particles with desired orientation flowing through a bottleneck
(201812)"We report extensive numerical simulations of the flow of anisotropic selfpropelled particles through a constriction. In particular, we explore the role of the particles’ desired orientation with respect to the moving ... 
Redefining the role of obstacles in pedestrian evacuation
(2018)"The placement of obstacles in front of doors is believed to be an effective strategy to increase the flow of pedestrians, hence improving the evacuation process. Since it was first suggested, this counterintuitive feature ... 
Performance of nonfibre based dispersion compensation for longhaul 10.7 Gbit/s DWDM transmission
(2004)"Nonfibre based inline dispersion compensation is employed to achieve longhaul transmission of 80 channels at 10.7 Gbit=s bit rate over 1200 km of LEAF fibre. Average system margins of more than 4 dB and small transmission ... 
Impact of DCF properties on system design
(2006)"The dispersioncompensating ﬁber is an important optical element of current and future optical networks. In this paper, we review the impact that various properties of dispersioncompensating ﬁbers has on the performance ... 
Uncertainty relation for the optimization of opticalfiber transmission systems simulations
(2005)“The mathematical inequality which in quantum mechanics gives rise to the uncertainty principle between two non commuting operators is used to develop a spatial stepsize selection algorithm for the SplitStep Fourier ... 
Stochastic resonance and brownian ratchets
(2005)"We discuss the connections between Brownian ratchets (BR) and stochastic resonance (SR). We consider a periodic potential energy landscape with no left–right symmetry that is driven by an external force which can be ... 
Order and disorder in the local evolutionary minority game
(2005)"We study a modification of the Evolutionary Minority Game (EMG) in which agents are placed in the nodes of a regular or a random graph. A neighborhood for each agent can thus be defined and a modification of the usual ... 
The evolutionary minority game with local coordination
(2003)"We discuss a modification of the evolutionary minority game (EMG) in which agents are placed in the nodes of a regular or a random graph. A neighborhood for each agent can thus be defined and a modification of the usual ... 
Why nestedness in mutualistic networks?
(2007)"We investigate the relationship between the nested organization of mutualistic systems and their robustness against the extinction of species. We establish that a nested pattern of contacts is the best possible one as far ... 
A Geometrical View of Scalar Modulation Instability in Optical Fibers
(2017)"Full models of scalar modulation instability (MI) in optical fibers available in the literature usually involve complex formulations. In this paper, we present a novel approach to the analysis of MI in optical fibers by ... 
Optimum integration procedures for supercontinuum simulation
(2012)"We study numerical solutions of the generalized nonlinear Schrödinger equation (GNLSE), focusing on the advantage of integrating the nonlinear part of the equation in the frequency domain (FD), rather than in the time ...
