Diagnostics for spectropolarimetry and magnetography
An assessment on the capabilities of modern spectropolarimeters and
magnetographs is in order since most of our astrophysical results rely upon the
accuracy of the instrumentation and on the sensitivity of the observables to
variations of the sought physical parameters. A contribution to such an
assessment will be presented in this talk where emphasis will be made on the
use of the so-called response functions to gauge the probing capabilities of
spectral lines and on an analytical approach to estimate the uncertainties in
the results in terms of instrumental effects. The Imaging Magnetograph
eXperiment (IMaX) and the Polarimetric and Helioseismic Imager (PHI) will be
used as study cases.Comment: To be published in "Physics of Sun and Star Spots", Proceedings of

La inserción socioprofesional de los inmigrantes en Andalucía
En las últimas décadas, un fenómeno nuevo ha irrumpido de forma intensa, rápida y estable en las sociedades española y andaluza. Nos referimos a la inmigración económica. Las políticas sobre inmigración han mostrado un interés permanente en conseguir la integración social de los extranjeros en los países de acogida. La importancia del empleo no ha pasado desapercibida para las políticas de integración social ni para los propios inmigrantes económicos, ya que constituye la principal fuente de renta y de estatus de los individuos en nuestra sociedad. Partimos de la hipótesis, más verificada que rechazada, de que la integración social está íntimamente relacionada con la inserción en el mercado de trabajo y el desarrollo de unas trayectorias laborales estables. Por ello, en el presente artículo, nos centramos en analizar la inserción socioprofesional de los inmigrantes económicos en la comunidad autónoma de Andalucía como indicador fundamental a la hora de estimar sus posibilidades de integración social.In the last few decades a new phenomenon has burst intensively and rapidly into Spanish and Andalusian societies, and established itself: economic immigration. Immigration policies have shown a continuous interest in achieving the social integration of foreigners in host societies. The importance of employment has not gone unnoticed by social integration policies, nor by the economic immigrants themselves, since employment is the main source of income and status for individuals in our society. We begin from the hypothesis, more accepted than rejected, that achieving social integration is closely related to entering the labour market and maintaining stable employment. For this reason the present article focuses on analysing the socio-professional inclusion of economic immigrants in the autonomous community of Andalusia, as a fundamental indicator of their possibilities of social integratio
Applying A Methodology For Educating Students With Special Needs: A Case Study
The introduction of innovative educational technologies opens up new ways of interacting with students. We propose to exploit this potential to help in the education of children with special needs. We analyze the state of the art of tools supporting the teaching process, focusing on the omissions of existing research. We propose a new framework to help throughout the whole teaching process and describe its application to Proyecto Aprender (Learn Project), an educational resource targeting children with learning difficulties. Finally, we outline some conclusions and current/future research lines
El origen causal de la imposibilidad según Enrique de Gante
A critical translation of two quodlibetal questions by Henry of Ghent on the causal origin of impossibility, preceded by a preliminary study that analyses both questions within the general framework of his relational ontology. In the first one (VI.3), Henry concludes that the impossibility of something comes from the thing itself (ex parte rei); while in the second one (VIII.3), he holds that the impossibility of something comes from God (ex parte dei). The textual and philosophical analysis shows, on the one hand, the continuity and dependence of the second question on the first one, and, on the other hand, the weakness of the distinction between the formal constitution of the res and its objective possibility, as well as the originality and value of the notion of nothingness (purum nihil) proposed by Henry in both questions.Traducción crítica de las dos cuestiones quodlibetales dedicadas por Enrique de Gante al origen causal de la imposibilidad, precedida de un estudio introductorio que analiza ambas cuestiones en el marco general de su ontología relacional. En la primera (VI.3), Enrique concluye que la imposibilidad de algo proviene ex parte rei; mientras que en la segunda (VIII.3), concluye que la imposibilidad de algo proviene ex parte dei. El estudio de ambas cuestiones muestra, por una parte, la continuidad y la dependencia de la segunda cuestión respecto de la primera y, por otra, la debilidad de la distinción propuesta por Enrique entre la constitución formal de la res y su posibilidad objetiva, así como la originalidad y el valor de la noción de nada (purum nihil) que logra precisar en ellas
The molecular basis of complex phenotypes in the fire ant Solenopsis invicta
PhD ThesisUnderstanding the phenotypic diversity we observe across the tree of life is a fundamental
part of research in biology. A particular case of special interest is the occurrence of several
discrete phenotypes within the same population. These cases allow us to interrogate the
basis of phenotypic differences without the influence of confounding factors such as
phylogenetic distance or geographical barriers. The steady reduction in sequencing price of
the past decades has resulted in more molecular data available for specific organisms where
phenotypic differences occur within a single population.
This thesis focuses on one such organism, the fire ant Solenopsis invicta, to shed light on
the molecular basis of within population discrete phenotypic diversity. This species displays
two types of such differences. It is socially polymorphic, which means that colonies can have
two types of social organisation. Additionally, S. invicta has three types of morphological
castes: queens, workers and males. Social polymorphism in this species is determined
genetically, whereas caste differences are triggered by environmental cues during
development. S. invicta is thus a good study system to understand different molecular
mechanisms underlying discrete phenotypes. In this thesis, I use a combination of molecular
data and modelling approaches to investigate the molecular underpinning of both types of
phenotypic differences in S. invicta.
I show that the genetic architecture maintaining different types of social organisation is likely
to have arisen by a combination of evolutionary conflict and a strong influence of gene flow
fluctuations between phenotypes. I also show that caste differences depend on the
expression of thousands of genes, most of which are tissue specific. These results are put in
the context of the wider theoretical framework, and provide further understanding on the
evolution of phenotypic diversit
Moisture Evaporation from Granular Biopesticides Containing Quiescent Entomopathogenic Nematodes
The moisture evaporation process from granular biopesticides (GBs) containing entomopathogenic nematodes (EPNs) has influence in the shelf-life of these biological products, but the approach to design GBs with desired transport properties lacks of theoretical support to get closer in a better way to formulations design of long-term storage. In this chapter we review the state of art in theoretical studies about the physics of the moisture evaporation to elucidate what are the mechanisms of drying of GBs. We found that several external and internal factors influence the transport process of moisture exchange among others phenomenon that happened in a porous media such as GBs; consequently, complex and highly dynamic interactions between medium properties, transport processes, and boundary conditions result in a wide range of evaporation behaviors. The theory of drying process in two stages for porous materials with high moisture content seems to be a good starting point to explore further the drying of GBs at different scales and mechanistic and correlative models of evaporation are available to analyze the desiccation in different stages of the elaboration process, which is also of interest in the subject area of science and technology of the formulation of EPNs
Using collocation segmentation to augment the phrase table
This paper describes the 2010 phrase-based statistical machine translation system developed at the TALP Research Center of the UPC1 in cooperation with BMIC2 and VMU3. In phrase-based SMT, the phrase table is the main tool in translation. It is created extracting phrases from an aligned parallel corpus and then computing translation model scores with them. Performing a collocation segmentation over the source and target corpus before the alignment causes that di erent and larger phrases are extracted from the same original documents. We performed this segmentation and used the union of this phrase set with the phrase set extracted from the nonsegmented corpus to compute the phrase table. We present the con gurations considered and also report results obtained with internal and o cial test sets.Postprint (published version
