It's usually believed that the idea of applying logical methods to constructivist phenomenalism was, --in general- a result of Russell's originality. In this paper is argued that some important ideas were in fact due to Mach, Moore and Whitehead. According to the author, Russell got from Mach the general idea of epistemology as an analysis of scientific concepts and, specially,the idea of sensations as the building blocks for his logical construction. Moore made Russell believe that only sensations are known in a direct way, and so, the existence of external objects as the cause of our perceptions is only inferred. Moreover, according to the author, Russell's views on sense data -his sensibilia- are also due to Moore. Finally, Russell got from Whitehead the idea of the phenomenical reconstruction as an alternative to the causal theory of perception, and also how the logical construction should be done. The author undertakes also a detailed analysis of some early works of Whitehead not very well known.

Through the graphic novel V for Vendetta by Alan Moore and David Lloyd, I problematize here the act of classification of the subgenres within each genre. This is a literary study that aims to reflect on the utopian genre. It is a genre which requires in order to be understood a consideration of society and its organization. The concept of society cannot be properly discussed without mentioning the surface on which it is based: people with their selves and their bodies. Institutions and conventions act subtly and constantly on us, offering more or less free roles, usually related to a particular physical appearance, as may be the mode of dress, or gesture- and generating a negotiation between our desires and our duties. In other words, they act on us to transform us into people suitable for the smooth running of the community

We characterize double adjunctions in terms of presheaves and universal squares, and then apply these characterizations to free monads and Eilenberg-Moore objects in double categories. We improve upon an earlier result of Fiore-Gambino-Kock in [7] to conclude: if a double category with cofolding admits the construction of free monads in its horizontal 2-category, then it also admits the construction of free monads as a double category horizontally and vertically, and also in its vertical 2-category. We also prove that a double category admits Eilenberg-Moore objects if and only if a certain parameterized presheaf is representable. Along the way, we develop parameterized presheaves on double categories and prove a double Yoneda Lemma.

Estudi realitzat a partir d’una estada a la Uniersity de Sheffield, Gran Bretanya, entre octubre del 2007 i febrer del 2008. El treball ha estat centrat en el debat entre liberals i conservadors sobre l’estructura de la justificació perceptiva. Avuí en dia hi ha molts filòsofs que retornen al dogmatisme del sentit comú proclamat per G.E. Moore i la seva Prova sobre el Món Extern: I-Hi ha alguna cosa que sembla una mà; II-Hi ha una mà; III-Hi ha un món extern. És àmpliament acceptat que aquesta prova no constitueix una resposta satisfactòria a l’escepticisme sobre el nostre dret a dir que sabem, però quan es tracta de caracteritzar per què no és satisfactòria hi ha desacord. Això ha dut a encetar el debat entre liberals i conservadors pel qu fa a l’estructura de la justificació perceptiva.

El tratamiento del carcinoma de páncreas continúa siendo uno de los grandes retos de la Oncología Médica. Un mejor conocimiento de las vías moleculares que intervienen en su desarrollo ha contribuido al uso de nuevos agentes terapéuticos dirigidos frente a las mismas. Una de esas vías es la del EGFR. Moore et al llevaron a cabo en 2007 un ensayo fase III aleatorizado en el que compararon gemcitabina frente a gemcitabina y erlotinib (un inhibidor de EGFR) y en el que demostraron de forma estadísticamente significativa por primera vez una mejoría en supervivencia global al asociar un agente a la gemcitabina en el tratamiento del adenocarcinoma pancreático avanzado. Hemos adoptado el esquema empleado en el ensayo fase III de Moore como primera línea de tratamiento del carcinoma pancreático localmente avanzado e irresecable y metastático en nuestro centro y creo necesario analizar la toxicidad y la supervivencia observada en nuestro medio. Para ello presento los resultados de eficacia, toxicidad y supervivencia global en la serie de 55 pacientes tratados con dicho esquema entre octubre de 2007 y octubre de 2010 en nuestro centro.

The increasing volume of data describing humandisease processes and the growing complexity of understanding, managing, and sharing such data presents a huge challenge for clinicians and medical researchers. This paper presents the@neurIST system, which provides an infrastructure for biomedical research while aiding clinical care, by bringing together heterogeneous data and complex processing and computing services. Although @neurIST targets the investigation and treatment of cerebral aneurysms, the system’s architecture is generic enough that it could be adapted to the treatment of other diseases.Innovations in @neurIST include confining the patient data pertaining to aneurysms inside a single environment that offers cliniciansthe tools to analyze and interpret patient data and make use of knowledge-based guidance in planning their treatment. Medicalresearchers gain access to a critical mass of aneurysm related data due to the system’s ability to federate distributed informationsources. A semantically mediated grid infrastructure ensures that both clinicians and researchers are able to seamlessly access andwork on data that is distributed across multiple sites in a secure way in addition to providing computing resources on demand forperforming computationally intensive simulations for treatment planning and research.

Remote sensing spatial, spectral, and temporal resolutions of images, acquired over a reasonably sized image extent, result in imagery that can be processed to represent land cover over large areas with an amount of spatial detail that is very attractive for monitoring, management, and scienti c activities. With Moore's Law alive and well, more and more parallelism is introduced into all computing platforms, at all levels of integration and programming to achieve higher performance and energy e ciency. Being the geometric calibration process one of the most time consuming processes when using remote sensing images, the aim of this work is to accelerate this process by taking advantage of new computing architectures and technologies, specially focusing in exploiting computation over shared memory multi-threading hardware. A parallel implementation of the most time consuming process in the remote sensing geometric correction has been implemented using OpenMP directives. This work compares the performance of the original serial binary versus the parallelized implementation, using several multi-threaded modern CPU architectures, discussing about the approach to nd the optimum hardware for a cost-e ective execution.

Ran, the small, predominantly nuclear GTPase, has been implicated in the regulation of a variety of cellular processes including cell cycle progression, nuclear-cytoplasmic trafficking of RNA and protein, nuclear structure, and DNA synthesis. It is not known whether Ran functions directly in each process or whether many of its roles may be secondary to a direct role in only one, for example, nuclear protein import. To identify biochemical links between Ran and its functional target(s), we have generated and examined the properties of a putative Ran effector mutation, T42A-Ran. T42A-Ran binds guanine nucleotides as well as wild-type Ran and responds as well as wild-type Ran to GTP or GDP exchange stimulated by the Ran-specific guanine nucleotide exchange factor, RCC1. T42A-Ran·GDP also retains the ability to bind p10/NTF2, a component of the nuclear import pathway. In contrast to wild-type Ran, T42A-Ran·GTP binds very weakly or not detectably to three proposed Ran effectors, Ran-binding protein 1 (RanBP1), Ran-binding protein 2 (RanBP2, a nucleoporin), and karyopherin ß (a component of the nuclear protein import pathway), and is not stimulated to hydrolyze bound GTP by Ran GTPase-activating protein, RanGAP1. Also in contrast to wild-type Ran, T42A-Ran does not stimulate nuclear protein import in a digitonin permeabilized cell assay and also inhibits wild-type Ran function in this system. However, the T42A mutation does not block the docking of karyophilic substrates at the nuclear pore. These properties of T42A-Ran are consistent with its classification as an effector mutant and define the exposed region of Ran containing the mutation as a probable effector loop.

The edge excitations and related topological orders of correlated states of a fast rotating Bose gas are studied. Using exact diagonalization of small systems, we compute the energies and number of edge excitations, as well as the boson occupancy near the edge for various states. The chiral Luttinger-liquid theory of Wen is found to be a good description of the edges of the bosonic Laughlin and other states identified as members of the principal Jain sequence for bosons. However, we find that in a harmonic trap the edge of the state identified as the Moore-Read (Pfaffian) state shows a number of anomalies. An experimental way of detecting these correlated states is also discussed.

L'objectiu d'aquest article és mostrar les percepcions del professorat de llengües clàssiques (grec antic i llatí) amb relació a les activitats en línia fetes durant els cursos. L'estudi es va fer a tres països: Grècia (a tres universitats importants), Espanya (a la Universitat de Barcelona) i els Estats Units (a la Universitat de Califòrnia a Berkeley) amb la participació de trenta-tres professors. Segons el nivell d'ús i d'acceptació de les TIC i a partir de la classificació de G. Moore, vam separar els docents participants en tres grups: els conservadors, el corrent principal i els adoptadors primerencs. El fet que el grup més petit sigui el tercer mostra clarament que hi ha una necessitat de preparació i formació dels professors abans d'introduir projectes innovadors a l'aula. Com que el punt d'inici de l'aplicació d'innovació a l'aula és el professorat, els responsable dels projectes d'innovació s'haurien de centrar a ajudar-los a conscienciar-se dels canvis en els mètodes d'ensenyament i a incloure la seva opinió durant el disseny dels esmentats projectes.
