Loosening the notions of compliance and sub-behaviour in client/server systems
In the context of "session behaviors" for client/server systems, we propose a
weakening of the compliance and sub-behaviour relations where the bias toward
the client (whose "requests" must be satisfied) is pushed further with respect
to the usual definitions, by admitting that "not needed" output actions from
the server side can be "skipped" by the client. Both compliance and
sub-behaviour relations resulting from this weakening remain decidable, though
the proof of the duals-as-minima property for servers, on which the
decidability of the sub-behaviour relation relies, requires a tighter analysis
of client/server interactions.Comment: In Proceedings ICE 2014, arXiv:1410.701
Heavy fermion d-wave superconductivity: a X-boson approach
From an extension of the periodic Anderson model (PAM) in the
limit taking into account the effect of a nearest neighbor attractive
interaction between -electrons, we compare the obtained superconducting
phase diagram of a two dimensional d-wave superconductor with the results
obtained for an isotropic s-wave superconductor employing the X-boson method.Comment: Submitted to the Proceeding of the ICM 2003-Rome. Requires

On the heating of source of the Orion KL hot core
We present images of the J=10-9 rotational lines of HC3N in the vibrationally
excited levels 1v7, 1v6 and 1v5 of the hot core (HC) in Orion KL. The images
show that the spatial distribution and the size emission from the 1v7 and 1v5
levels are different. While the J=10-9 1v7 line has a size of 4''x 6'' and
peaks 1.1'' NE of the 3 mm continuum peak, the J=10--9 1v5 line emission is
unresolved (<3'') and peaks 1.3'' south of the 3 mm peak. This is a clear
indication that the HC is composed of condensations with very different
temperatures (170 K for the 1v7 peak and K for the 1v5 peak). The
temperature derived from the 1v7 and 1v5 lines increases with the projected
distance to the suspected main heating source I. Projection effects along the
line of sight could explain the temperature gradient as produced by source I.
However, the large luminosity required for source I, >5 10^5 Lsolar, to explain
the 1v5 line suggests that external heating by this source may not dominate the
heating of the HC. Simple model calculations of the vibrationally excited
emission indicate that the HC can be internally heated by a source with a
luminosity of 10^5 Lsolar, located 1.2'' SW of the 1v5 line peak (1.8'' south
of source I). We also report the first detection of high-velocity gas from
vibrationally excited HC3N emission. Based on excitation arguments we conclude
that the main heating source is also driving the molecular outflow. We
speculate that all the data presented in this letter and the IR images are
consistent with a young massive protostar embedded in an edge-on disk.Comment: 13 pages, 3 figures, To be published in Ap.J. Letter
State of the issue and new challenges of Social Work: reflections of recently graduated professionals from Peru and Spain
Currently the primacy of the market economy in most of the nations is constituted as a global phenomenon, which has direct consequences on the structure of the different states socio-political systems. In this framework, the way in which the relations between the market and each nation-state are materialized, including their intervention strategies, generate differential contexts with relevant implications in various areas, including education. These relationships deeply affect the social protection systems and especially the Public System of Social Services, traditionally associated with the most vulnerable and less economically solvent population. The discipline of Social Work is no stranger to this situation, living in recent years convulsive moments both in terms of the construction of own knowledge and in the practice of the profession. Given this situation, it is intended to obtain the discourse that social workers have on aspects as important as the relevance of the training model, the significance given to research, the social imaginary around the discipline or the adequacy of the available resources for the exercise of the profession.Universidad de Málaga.

Posterior moments and quantiles for the normal location model with Laplace prior
We derive explicit expressions for arbitrary moments and quantiles of the posterior distribution of the location parameter eta in the normal location model with Laplace prior, and use the results to approximate the posterior distribution of sums of independent copies of eta
