Positive ion extraction across the superfluid-vapor helium interface
2009
The extraction efficiency of positive (219)Rn ions across the superfluid-vapor helium interface above similar to 1.3 K indicates that extraction results from thermal activation across a barrier of about 20 K. Below similar to 1.3 K, the extraction efficiency is constant at about 0.7%. The evaporation of the superfluid surface by second sound pulses has a negative impact on the ion extraction, but not on the ions themselves. It takes 3.2( 6) s at 1.60 K and 15( 6) s at 1.15 K for the extraction process to recover from a disturbed state of yet unknown nature.
Multiplet coupling and band structure in L2,3-edge XAS through multi-channel multiple scattering theory.
2009
International audience; Using the recently developed multi-channel multiple scattering (MCMS) method we have calculated the x-ray absorption spectra (XAS) at the L2,3-edge of transition metal compounds. The MCMS method is an ab initio scheme which combines an accurate description of the band structure of the material with a correlated many-electron wave function on the absorber atom. Thereby configuration interaction in the XAS final state, in particular multiplet effects, can be taken into account. In the present implementation, we use an electron-hole wave function and treat the interaction with all other electrons on a mean-field level. The calculated spectra agree well with experiment f…
Measurements of ground-state properties for nuclear structure studies by precision mass and laser spectroscopy
2011
Atomic physics techniques like Penning-trap and storage-ring mass spectrometry as well as laser spectroscopy have provided sensitive high-precision tools for detailed studies of nuclear ground-state properties far from the valley of β-stability. Mass, moment and nuclear charge radius measurements in long isotopic and isotonic chains have allowed extraction of nuclear structure information such as halos, shell and subshell closures, the onset of deformation, and the coexistence of nuclear shapes at nearly degenerate energies. This review covers experimental precision techniques to study nuclear ground-state properties and some of the most recent results for nuclear structure studies.

Finite-range separable pairing interaction within the new N3LO DFT approach
2011
For over four decades, the Skyrme functional within various parametrizations has been used to calculate nuclear properties. In the last few years there was a number of attempts to improve its performance and introduce generalized forms. In particular, the most general phenomenological quasi-local energy density functional, which contains all combinations of density, spin-density, and their derivatives up to the sixth order (N3LO), was proposed in [1]. Since in the phenomenological-functional approaches, the particle-particle (pp) channel is treated independently of the particle-hole (ph) channel, there remains a question of what pairing interaction is suitable to use within the N3LO energy …
Path integral solution by fractional calculus
2008
In this paper, the Path Integral solution is developed in terms of complex moments. The method is applied to nonlinear systems excited by normal white noise. Crucial point of the proposed procedure is the representation of the probability density of a random variable in terms of complex moments, recently proposed by the first two authors. Advantage of this procedure is that complex moments do not exhibit hierarchy. Extension of the proposed method to the study of multi degree of freedom systems is also discussed.
Digital Cultural Heritage

Most contemporary thinkers agree that we are going through a time of historical change, building adifferent concept and model of social interrelation. Our ways of life and work have changed, as havethe ways in which we communicate and relate to each other.
SIGIC-UV: Sistema Inform�tico de Garant�a Interna de Calidad para los centros y titulaciones de la
2015
Arran de la posada en marxa de l’espai europeu d’educacio superior, les universitats espanyoles han dissenyat sistemes de garantia interna de qualitat per als seus centres i les seues titulacions. Aquest article presenta en detall el Sistema Informatic de Garantia Interna de Qualitat de la Universitat de Valencia (SIGIQ-UV), una eina informatica de codi obert que integra tecnologies de gestio de processos de negoci amb tecnologies de repositori documental per al seguiment dels procediments de qualitat i l’emmagatzematge de les evidencies documentals resultants de la seua execucio. L’aproximacio modular amb que ha estat desenvolupat garanteix la flexibilitat del sistema, l’estat d’implantaci…
Actitudes de docentes y discentes ante la otra: la madre universitaria
2019
INTRODUCCIO. Aquesta investigacio intenta descobrir les experiencies de les persones que son mares i al mateix temps alumnes en l’educacio superior, que miren d’equilibrar les moltes responsabilitats associades amb els seus papers de mare, membre de la familia, amiga i estudiant universitaria. S’aborda la problematica de la conciliacio estudiantil familiar des d’una perspectiva de genere. METODE. En aquest estudi, a partir d’una metodologia feminista qualitativa basada en narratives mitjancant entrevistes semiestructurades, s’analitzen les creences i actituds d’un total de tretze estudiants universitaries. RESULTATS. A traves del pensament narratiu, emprem les seves histories com un mitja p…
