Rare event simulation with fully automated Importance splitting
(2015)Probabilistic model checking is a powerful tool for analysing probabilistic systems but it can only be efficiently applied to Markov models. Monte Carlo simulation provides an alternative for the generality of stochastic ... -
Reaction rate in an evanescent random walkers system
(2015)Diffusion mediated reaction models are particularly ubiquitous in the description of phys-ical, chemical or biological processes. The random walk schema is a useful tool for formu-lating these models. Recently, evanescent ... -
La realidad de los átomos
(2015)En este trabajo nos proponemos reconsiderar, desde una perspectiva histórica, la contribución de Albert Einstein a la de la teoría molecular de la realidad con sus trabajos sobre el movimiento Browniano. -
Recent developments in GEANT 4
(2016)GEANT4 is a software toolkit for the simulation of the passage of particles through matter. It is used by a large number of experiments and projects in a variety of application domains, including high energy physics, ... -
Resonance states in a cylindrical quantum dot with an external magnetic field
(2014)Bound and resonance states of quantum dots play a significant role in photo-absorption processes. In this work, we analyze a cylindrical quantum dot, its spectrum and, in particular, the behaviour of the lowest resonance ... -
Search for gravitational radiation from intermediate mass black hole binaries in data from the second LIGO-Virgo joint science run
(2014)This paper reports on an unmodeled, all-sky search for gravitational waves from merging intermediate mass black hole binaries (IMBHB). The search was performed on data from the second joint science run of the LIGO and Virgo ... -
Search for gravitational wave ringdowns from perturbed intermediate mass black holes in LIGO-Virgo data from 2005-2010
(2014)We report results from a search for gravitational waves produced by perturbed intermediate mass black holes (IMBH) in data collected by LIGO and Virgo between 2005 and 2010. The search was sensitive to astrophysical sources ... -
Search for gravitational waves associated with gamma-ray bursts detected by the InterPlanetary Network
(2014)We present the results of a search for gravitational waves associated with 223 γ-ray bursts (GRBs) detected by the InterPlanetary Network (IPN) in 2005-2010 during LIGO´s fifth and sixth science runs and Virgo´s first, ... -
Searches for continuous gravitational waves from nine young supernova remnants
(2015)We describe directed searches for continuous gravitational waves (GWs) in data from the sixth Laser Interferometer Gravitational-wave Observatory (LIGO) science data run. The targets were nine young supernova remnants not ... -
Selección de parcelas control para estudios de la dinámica post-incendio : desempeño de rutinas no paramétricas y autorregresivas
(2017)Los regímenes naturales de incendios han sufrido modificaciones; consecuentemente, es indispensable disponer de herramientas robustas para el seguimiento post-fuego de la vegetación. Los satélites de alta resolución temporal ... -
Self-avoiding walks on a bilayer Bethe lattice
(2014)We propose and study a model of polymer chains in a bilayer. Each chain is confined in one of the layers and polymer bonds on first neighbor edges in different layers interact. We also define and comment results for a ... -
Silver L1, L2 and L3 cross-sections for ionization and x-ray production by electron impact
(2014)The experimental determination of ionization cross-sections and total x-ray production cross-sections under electron impact is carried out for the three silver L-subshells. The very complex spectral structure involving ... -
SiNaRaMe : integración de una red de radares hidro-meteorológicos en latinoamérica
(2017)Pocos países en Latinoamérica poseen radares meteorológicos operativos y, menos aún, han logrado la integración de estos mediante una red, junto a otros instrumentos y sensores remotos para monitoreo hidro-meteorológico. ... -
Single-parameter spin-pumping in driven metallic rings with spin-orbit coupling
(2014)We consider the generation of a pure spin-current at zero bias voltage with a single time-dependent potential. To such end we study a device made of a mesoscopic ring connected to electrodes and clarify the interplay between ... -
Smart sampling for lightweight verification of Markov decision processes
(2015)Markov decision processes (MDP) are useful to model optimisation problems in concurrent systems. To verify MDPs with efficient Monte Carlo techniques requires that their nondeterminism be resolved by a scheduler. Recent ... -
Solid-state studies of the crystalline/amorphous character in linear Poly(ethylenimine hydrochloride) (PEI-HCl) polymers and their copper complexes
(2015)Linear poly(ethylenimine hydrochloride) (PEI-HCl) polymers with different molecular weights (22, 87, and 217 kDa) and their copper complexes (Cu−PEI) were studied with particular attention to the crystalline/amorphous ... -
Some totally geodesic submanifolds of the nonlinear Grassmannian of a compact symmetric space
(2014)Let M and N be two connected smooth manifolds, where M is compact and oriented and N is Riemannian. Let E be the Fréchet manifold of all embeddings of M in N, endowed with the canonical weak Riemannian metric. Let ∼ be the ... -
Spectra of lens spaces from 1-norm spectra of congruence lattices
(2016)To every n-dimensional lens space L, we associate a congruence lattice L in Zm, with n = 2m−1 and we prove a formula relating the multiplicities of Hodge-Laplace eigenvalues on L with the number of lattice elements of a ... -
Spherical analysis on homogeneous vector bundles of the 3-dimensional euclidean motion group
(2018)We consider R3 as a homogeneous manifold for the action of the motion group given by rotations and translations. For an arbitrary τ∈SO(3)ˆ, let Eτ be the homogeneous vector bundle over R3 associated with τ. An interesting ... -
Spherical functions : the spheres vs the projective spaces
(2014)In this paper we establish a close relationship between the spherical functions of the n-dimensional sphere Sn ≃ SO(n + 1)/SO(n) and the spherical functions of the n-dimensional real projective space P n(R) ≃ SO(n + ...
