Large deviations for non-uniformly expanding maps
We obtain large deviation results for non-uniformly expanding maps with
non-flat singularities or criticalities and for partially hyperbolic
non-uniformly expanding attracting sets. That is, given a continuous function
we consider its space average with respect to a physical measure and compare
this with the time averages along orbits of the map, showing that the Lebesgue
measure of the set of points whose time averages stay away from the space
average decays to zero exponentially fast with the number of iterates involved.
As easy by-products we deduce escape rates from subsets of the basins of
physical measures for these types of maps. The rates of decay are naturally
related to the metric entropy and pressure function of the system with respect
to a family of equilibrium states. The corrections added to the published
version of this text appear in bold; see last section for a list of changesComment: 36 pages, 1 figure. After many PhD students and colleagues having
pointed several errors in the statements and proofs, this is a correction to
published article answering those comments. List of main changes in a new

Women in the mutual societies of Portugal from the end of the nineteenth century to the 1930s
This chapter aims to express recent research on the history of women’s work and activism by focusing on women in the mutual societies of Portugal from a gender perspective. The main objective is thus analysing women’s rights and the discrimination prevailing in mixed associations (including women and men as members). Another central purpose involves recognising women-only associations as a space for meeting and collaboration amongst working-class women and feminists that attained a voice in the mutualism movement in which their claims on welfare issues targeted both themselves and their children. Furthermore, we seek to demonstrate that only in women’s mutual associations did the ideals of democracy and equality, advocated by mutualism, become fulfilled for women. However, in fact, only a few women participated in the mutualism congresses during the First Republic, with some women gaining prominent places in the Assemblies but without any known public interventions according to the sources.info:eu-repo/semantics/acceptedVersio
Black hole formation in bidimensional dilaton gravity coupled to scalar matter systems
This work deals with the formation of black hole in bidimensional dilaton
gravity coupled to scalar matter fields. We investigate two scalar matter
systems, one described by a sixth power potential and the other defined with
two scalar fields containing up to the fourth power in the fields. The
topological solutions that appear in these cases allow the formation of black
holes in the corresponding dilaton gravity models.Comment: Latex, 9 pages. Published in Mod. Phys. Lett. A14 (1999) 268
Dilaton Gravity with a Non-minmally Coupled Scalar Field
We discuss the two-dimensional dilaton gravity with a scalar field as the
source matter. The coupling between the gravity and the scalar, massless, field
is presented in an unusual form. We work out two examples of these couplings
and solutions with black-hole behaviour are discussed and compared with those
found in the literature
The First Year of the Large Hadron Collider: A Brief Review
The first year of LHC data taking provided an integrated luminosity of about
35/pb in proton-proton collisions at sqrt(s)=7 TeV. The accelerator and the
experiments have demonstrated an excellent performance. The experiments have
obtained important physics results in many areas, ranging from tests of the
Standard Model to searches for new particles. Among other results the physics
highlights have been the measurements of the W-, Z-boson and t t-bar production
cross-sections, improved limits on supersymmetric and other hypothetical
particles and the observation of jet-quenching, elliptical flow and J/Psi
suppression in lead-lead collisions at sqrt(sNN) = 2.76 TeV.Comment: 11 pages, 9 figures, invited brief review for Mod. Phys. Lett.
Mértola in Late Antiquity: new archeological and epigraphic data
En Mértola se ha encontrado recientemente un considerable grupo de inscripciones paleocristianas que se asocian a dos monumentos de la Antigüedad TardÃa. Uno de ellos parcialmente conocido, otro totalmente inédito. Los dos han sido objeto de excavaciones entre 2008 y 2009. Los nuevos textos epigráficos vienen a aumentar la ya numerosa colección epigráfica conocida y a reforzar la idea del uso de las lenguas griega y latina en el seno de una misma comunidad, la del puerto fluvial de Mértola, en el siglo VI d.C.Recently a new group of paleochristian inscriptions and two new monuments were found in Mértola. One of them was already known, but the other was ignored till now. Both were excavated between 2008 and 2009. The new epigraphic texts increase the large epigraphical collection already known, reinforcing the idea that both latin and greek were used within the same community, in the fluvial harbour of Mértola, in VI century a.C
