Support Vector Machines with Applications
Javier M. Moguerza, Alberto Muñoz
Support vector machines (SVMs) appeared in the early nineties as optimal margin classifiers in the context of Vapnik's statistical learning theory. Since then SVMs have been succes…
Synchronization in semiconductor laser rings
Javier M. Buldu, M. C. Torrent, Jordi Garcia-Ojalvo
We examine the dynamics of semiconductor lasers coupled in a ring configuration. The lasers, which have stable output intensity when isolated, behave chaotically when coupled unidi…
The Social Network of Contemporary Popular Musicians
Juyong Park, Oscar Celma, Markus Koppenberger +2
In this paper we analyze two social network datasets of contemporary musicians constructed from allmusic.com (AMG), a music and artists' information database: one is the collaborat…
Coincidence detection of inharmonic pulses in a nonlinear crystal
Xavier Vidal, Pablo Balenzuela, Javier M. Buldú +2
Two trains of light pulses at periods that are equally shifted from the harmonics of a missing fundamental, are combined in a nonlinear crystal. As a result of a noncollinear phase…
Quantum Capacities of Channels with small Environment
Michael M. Wolf, David Perez-Garcia
We investigate the quantum capacity of noisy quantum channels which can be represented by coupling a system to an effectively small environment. A capacity formula is derived for a…
Synchronization by dynamical relaying in electronic circuit arrays
Iacyel Gomes Da Silva, Javier M. Buldú, Claudio R. Mirasso +1
We experimentally study the synchronization of two chaotic electronic circuits whose dynamics is relayed by a third parameter-matched circuit, to which they are coupled bidirection…
High-frequency effects in the FitzHugh-Nagumo neuron model
David Cubero, José Pablo Baltanás, Jesús Casado-Pascual
The effect of a high-frequency signal on the FitzHugh-Nagumo excitable model is analyzed. We show that the firing rate is diminished as the ratio of the high-frequency amplitude to…
Quantum Capacities of Bosonic Channels
Michael M. Wolf, David Perez-Garcia, Geza Giedke
We investigate the capacity of bosonic quantum channels for the transmission of quantum information. Achievable rates are determined from measurable moments of the channel by showi…
Bistable phase control via rocking in a nonlinear electronic oscillator
Javier M. Buldu, K. Staliunas, J. A. Casals +1
We experimentally demonstrate the effective rocking of a nonlinear electronic circuit operating in a periodic regime. Namely, we show that driving a Chua circuit with a periodic si…
Episodic synchronization in dynamically driven neurons
Pablo Balenzuela, Javier M. Buldu, Marcos Casanova +1
We examine the response of type II excitable neurons to trains of synaptic pulses, as a function of the pulse frequency and amplitude. We show that the resonant behavior characteri…
Sparse repulsive coupling enhances synchronization in complex networks
I. Leyva, I. Sendiña-Nadal, J. A. Almendral +1
Through the last years, different strategies to enhance synchronization in complex networks have been proposed. In this Letter, we show that the synchronization in a small-world ne…
Optimality of programmable quantum measurements
David Perez-Garcia
We prove that for a programmable measurement device that approximates every POVM with an error , the dimension of the program space has to grow at least polynomially with $\…
Contractivity of positive and trace preserving maps under norms
David Perez-Garcia, Michael M. Wolf, Denes Petz +1
We provide a complete picture of contractivity of trace preserving positive maps with respect to -norms. We show that for contractivity holds in general if and only if the…
A Theory of Routing for Large-Scale Wireless Ad-Hoc Networks
Antonio J. Caamaño, Juan J. Vinagre, Mark Wilby +1
In this work we develop a new theory to analyse the process of routing in large-scale ad-hoc wireless networks. We use a path integral formulation to examine the properties of the…
