Scaling stellar jets to the laboratory: the power of simulations
Chantal Stehle, Andrea Ciardi, Jean-Philippe Colombier +5
Advances in laser and Z-pinch technology, coupled with the development of plasma diagnostics and the availability of high-performance computers, have recently stimulated the growth…
Variational Inducing Kernels for Sparse Convolved Multiple Output Gaussian Processes
Mauricio A. Álvarez, David Luengo, Michalis K. Titsias +1
Interest in multioutput kernel methods is increasing, whether under the guise of multitask learning, multisensor networks or structured output data. From the Gaussian process persp…
Efficient Local Unfolding with Ancestor Stacks
G. Puebla, E. Albert, M. Hermenegildo
The most successful unfolding rules used nowadays in the partial evaluation of logic programs are based on well quasi orders (wqo) applied over (covering) ancestors, i.e., a subseq…
Statistics and geometry of cosmic voids
Jose Gaite
We introduce new statistical methods for the study of cosmic voids, focusing on the statistics of largest size voids. We distinguish three different types of distributions of voids…
The relation between Pearson's correlation coefficient r and Salton's cosine measure
Leo Egghe, Loet Leydesdorff
The relation between Pearson's correlation coefficient and Salton's cosine measure is revealed based on the different possible values of the division of the L1-norm and the L2-norm…
Universal Response of Quantum Systems with Chaotic Dynamics
Diego A. Wisniacki, Natalia Ares, Eduardo Vergini
The prediction of the response of a closed system to external perturbations is one of the central problems in quantum mechanics, and in this respect, the local density of states (L…
Superscars in the LiNC=LiCN isomerization reaction
S. D. Prado, E. Vergini, R. M. Benito +1
We demonstrate the existence of superscarring in the LiNC=LiCN isomerization reaction described by a realistic potential interaction in the range of readily attainable experimental…
Fast ignition of inertial fusion targets by laser-driven carbon beams
J. J. Honrubia, J. C. Fernandez, M. Temporal +2
Two-dimensional simulations of ion beam driven fast ignition are presented. Ignition energies of protons with Maxwellian spectrum and carbon ions with quasimonoenergetic and Maxwel…
Geometric structures modeled on affine hypersurfaces and generalizations of the Einstein Weyl and affine hypersphere equations
Daniel J. F. Fox
An affine hypersurface (AH) structure is a pair comprising a conformal structure and a projective structure such that for any torsion-free connection representing the projective st…
High-frequency propagation for the Schroedinger equation on the torus
Fabricio Macia
The main objective of this paper is understanding the propagation laws obeyed by high-frequency limits of Wigner distributions associated to solutions to the Schroedinger equation…
Composition law of cardinal order permutations
Jesus San Martin, Ma. Jose Moscoso, A. Gonzalez Gomez
In this paper the theorems that determine composition laws for both cardinal ordering permutations and their inverses are proven. So, the relative positions of points in a hs-perio…
Self-inverse Sheffer sequences and Riordan involutions
Ana Luzon, Manuel A. Moron
In this short note we focus on self-inverse Sheffer sequences and involutions in the Riordan group. We translate the results of Brown and Kuczma on self-inverse sequences of Sheffe…
Local Behavior of the First-Order Gradient Correction to the Thomas-Fermi Kinetic Energy Functional
David Garcia-Aldea, T. Martin-Blas, J. E. Alvarellos
The first order gradient correction to the Thomas-Fermi functional, proposed by Haq, Chattaraj and Deb (Chem. Phys. Lett. vol. 81, 8031, 1984) has been studied by evaluating both t…
Jamming transition in air transportation networks
Lucas Lacasa, Miguel Cea, Massimiliano Zanin
In this work we present a model of an air transportation traffic system from the complex network modelling viewpoint. In the network, every node corresponds to a given airport, and…
A geometric characterization of the upper bound for the span of the Jones polynomial
J. González-Meneses, P. M. G. Manchón
Let D be a link diagram with n crossings, s_A and s_B its extreme states and |s_AD| (resp. |s_BD|) the number of simple closed curves that appear when smoothing D according to s_A…
Iterative Processes Related to Riordan Arrays: The Reciprocation and the Inversion of Power Series
Ana Luzon
We point out how Banach Fixed Point Theorem, and the Picard successive approximation methods induced by it, allows us to treat some mathematical methods in Combinatorics. In partic…
Plateau insulator transition in graphene
M. Amado, E. Diez, D. López-Romero +5
The quantum Hall effect in a single-layer graphene sample is studied in strong magnetic fields up to 28 T. Our measurements reveal the existence of a metal- insulator transition fr…
Characterising equilibrium logic and nested logic programs: Reductions and complexity
David Pearce, Hans Tompits, Stefan Woltran
Equilibrium logic is an approach to nonmonotonic reasoning that extends the stable-model and answer-set semantics for logic programs. In particular, it includes the general case of…
Multipole corrections to perihelion and node line precession
L. Fernández-Jambrina
In this talk relativistic corrections due to Geroch-Hansen multipoles for perihelion precession and node line precession of orbits in a stationary axially symmetric vacuum spacetim…
Bianchi VI_0&III models. Self-similar approach
José Antonio Belinchón
We study several cosmological models with Bianchi VI_0&III symmetries under the self-similar approach. We find new solutions for the "classical" perfect fluid model as well as for…
A general stability criterion for switched linear systems having stable and unstable subsystems
Jesus San Martin, Anthony G. O'Farrell
We report conditions on a switching signal that guarantee that solutions of a switched linear systems converge asymptotically to zero. These conditions are apply to continuous, dis…
On non-singular inhomogeneous cosmological models
L. Fernández-Jambrina, L. M. González-Romero
In this talk we would like to review recent results on non-singular cosmological models. It has been recently shown that among stiff perfect fluid inhomogeneous spacetimes the abse…

Concetta Burgarella, Miguel Navascués, Álvaro Soto +2
In order to empirically assess the effect of actual seed sampling strategy on genetic diversity of holm oak (Quercus ilex) forestations in Sicily, we have analysed the genetic comp…
Estimation of a Probability with Guaranteed Normalized Mean Absolute Error
Luis Mendo
The estimation of a probability p from repeated Bernoulli trials is considered in this paper. A sequential approach is followed, using a simple stopping rule. A closed-form express…
