Gipsy 3D: Analysis, Visualization and Vo-Tools
The scientific goals of the AMIGA project are based on the analysis of a
significant amount of spectroscopic 3D data. In order to perform this work we
present an initiative to develop a new VO compliant package, including present
core applications and tasks offered by the Groningen Image Processing System
(GIPSY), and new ones based on use cases elaborated in collaboration with ad-
vanced users. One of the main goals is to provide local interoperability
between GIPSY (visualization and data analysis) and other VO software. The
connectivity with the Virtual Observatory environment will provide general
access to 3D data VO archives and services, maximizing the potential for
scientific discovery.Comment: 2 pages, 1 figure, to appear in the proceedings of the

Symmetries in Fluctuations Far from Equilibrium
Fluctuations arise universally in Nature as a reflection of the discrete
microscopic world at the macroscopic level. Despite their apparent noisy
origin, fluctuations encode fundamental aspects of the physics of the system at
hand, crucial to understand irreversibility and nonequilibrium behavior. In
order to sustain a given fluctuation, a system traverses a precise optimal path
in phase space. Here we show that by demanding invariance of optimal paths
under symmetry transformations, new and general fluctuation relations valid
arbitrarily far from equilibrium are unveiled. This opens an unexplored route
toward a deeper understanding of nonequilibrium physics by bringing symmetry
principles to the realm of fluctuations. We illustrate this concept studying
symmetries of the current distribution out of equilibrium. In particular we
derive an isometric fluctuation relation which links in a strikingly simple
manner the probabilities of any pair of isometric current fluctuations. This
relation, which results from the time-reversibility of the dynamics, includes
as a particular instance the Gallavotti-Cohen fluctuation theorem in this
context but adds a completely new perspective on the high level of symmetry
imposed by time-reversibility on the statistics of nonequilibrium fluctuations.
The new symmetry implies remarkable hierarchies of equations for the current
cumulants and the nonlinear response coefficients, going far beyond Onsager's
reciprocity relations and Green-Kubo formulae. We confirm the validity of the
new symmetry relation in extensive numerical simulations, and suggest that the
idea of symmetry in fluctuations as invariance of optimal paths has
far-reaching consequences in diverse fields.Comment: 8 pages, 4 figure
Beatriz Galindo : fortuna y poder de una humanista en la corte de los Reyes Católicos
La vida y la muerte están unidas en un testamento, a través de este documento –que es un
expediente formado por distintos documentos- podemos estudiar la forma de vida y los ingresos
de un matrimonio que representa muchos de los aspectos de la Corte de los Reyes Católicos:
Francisco RamÃrez de Madrid y Beatriz Galindo. Éstos asentaron una parte importante de su
fortuna en el Reino de Granada y en la ciudad de Málaga. Este documento también permite
conocer cómo la viuda, Beatriz Galindo, pudo apelar a los reyes porque estaba en desacuerdo
con la última voluntad de Francisco RamÃrez de Madrid.Life and death are linked in a testament, through this document –that is a file of different
records- we can study the way of life and the incomes of a couple that represented many aspects
of the Court of the Catholic Kings: Francisco RamÃrez de Madrid and Beatriz Galindo. They
settled an important part of they fortune in the Kingdom of Granada and in the city of Malaga.
This record also allows to know how the widow, Beatriz Galindo, could appealed the King and
Queen because she was in disagreement with the last wish of Francisco RamÃrez de Madrid
Villafranchian large mammals from the Iberian Peninsula: paleobiogeography, paleoecology and dispersal events
The Pleistocene of the Iberian Peninsula is currently a focus of intense paleontological, archaeological and geological research. To a large extent, these inquiries are intended to decipher the ecological factors that might have conditioned early Homo dispersals into the European continent during the late Early Pleistocene. In this respect, the research carried out during the last twenty years in several areas of the Iberian Peninsula (the Guadix-Baza Basin, the Sierra de Atapuerca, the VallparadÃs Section and the Banyoles-Besalú Basin) have yielded a large amount of new significant data. Here we review such data and provide for the first time a comprehensive synthesis from a faunal, geologiÂcal and paleoecological perspectives, by focusing on the relationship between paleoenvironmental conditions and early human dispersals during the late Early Pleistocene in the Iberian Peninsula. In particular, the Iberian fossil record of Early to Late Villafranchian large mamÂmals is synthesized, on the basis of recent publications and unpublished data collected by the authors during the last five years, in order to provide the adequate faunal and paleocological framework for understanding the factors that limited or conditioned human dispersal events.El Pleistoceno de la PenÃnsula Ibérica es actualmente foco de intensa investigación paleontológica, arqueológica y geológica. En gran medida, estos trabajos están encaminados a descifrar los factores ecológicos que podrÃan haber condicionado las dispersiones de los Homo iniciales hacia Europa durante el Pleistoceno inferior. En este sentido, la investigación realizada durante los últimos veinte años en diversas zonas de la PenÃnsula Ibérica (la Cuenca de Guadix-Baza, la Sierra de Atapuerca, la Sección de VallparadÃs y la Cuenca de Banyoles- Besalú) ha proporcionado una gran cantidad de nuevos datos significativos. Aquà revisamos estos datos y se proporciona por primera vez una sÃntesis exhaustiva desde una perspectiva paleontológica, paleoecológica y geológica, centrándonos en las relaciones entre las condiÂciones paleoambientales y las dispersiones de los primeros humanos en el Pleistoceno inferior de la PenÃnsula Ibérica. Concretamente, se sintetiza el registro fósil ibérico de grandes mamÃferos villafranquienses en base a publicaciones recientes y datos inéditos recopilados por los autores en los últimos cinco años, para asà proporcionar el marco faunÃstico y paleoecológico adecuado para comprender los factores que limitaron o condicionaron los eventos de dispersión humana
