Factorization of weakly continuous holomorphic mappings

We prove a basic property of continuous multilinear mappings between topological vector spaces, from which we derive an easy proof of the fact that a multilinear mapping (and a polynomial) between topological vector spaces is weakly continuous on weakly bounded sets if and only if it is weakly {\it uniformly\/} continuous on weakly bounded sets. This result was obtained in 1983 by Aron, Herv\'es and Valdivia for polynomials between Banach spaces, and it also holds if the weak topology is replaced by a coarser one. However, we show that it need not be true for a stronger topology, thus answering a question raised by Aron. As an application of the first result, we prove that a holomorphic mapping $f$ between complex Banach spaces is weakly uniformly continuous on bounded subsets if and only if it admits a factorization of the form $f=g\circ S$, where $S$ is a compact operator and $g$ a holomorphic mapping

Acercamiento psicoanalítico a los cantos de maldoror del Conde de Lautréamont

Exponer de qué forma se sitúa Maldoror frente al Creador, los adolescentes y el hombre. Mediante la propuesta de un esquema estructural se demuestra que el personaje manifiesta una subjetividad de ficción que explica gran parte de su acontecer. Aunque resulta pues, cuestión fundamental, imposible de ser definido o clasificado en una estructura psíquica pura, el trabajo tan sólo es una aproximación que facilita un acercamiento psicoanalítico al mismo y que hace visible que la presencia de respuestas tales como la voracidad, la agresión, la aniquilación, la identificación, el pase al acto8 , el desmembramiento y la anulación de la diferencia, por mencionar algunos, lo posicionan ficcionalmente ante el Otro a la manera de una paranoia.CONACY

Calidad de Vida: An Exploratory Investigation of Latino Breast Cancer Survivors and Intimate Partners

Advances in addressing psychosocial issues related to cancer treatment and prevention are not reaching all survivors equally. Latina breast cancer survivors and intimate partners are underrepresented in psychosocial interventions, and there is a scarcity of research on the influence of cancer on Latino couples’ quality of life. The purpose of this manuscript is to present findings from a trans-linguistic, dyadic qualitative research study aimed at exploring the influence of cancer on quality of life for Latina breast cancer survivors and their intimate partners. Results highlight several areas that are helpful and hindering to supporting survivorship

Dulce María Loynaz : un libro, un viaje y un gran amor. Notas y enigmas para un estudio de Jardín

The Spanish translation of Matilde Serao's book Ella non rispose, by Dulce Maria Loynaz, published in Cuba on 2013 and the introductory study made by the Cuban researcher Zaida Capote are the axes that motivate the following essay. The main purpose of this goes around Loynaz’s translation: the possible motivations that determined the choice of that book, such as some stylistic peculiarities present in the translating exercise and assessments of the “influence” of the Italian novel in Jardi

Topological first-order solitons in a gauged CP(2)CP(2) model with the Maxwell-Chern-Simons action

We verify the existence of radially symmetric first-order solitons in a gauged $CP(2)$ scenario in which the dynamics of the Abelian gauge field is controlled by the Maxwell-Chern-Simons action. We implement the standard Bogomol'nyi-Prasad-Sommerfield (BPS) formalism, from which we obtain a well-defined lower bound for the corresponding energy (i.e. the Bogomol'nyi bound) and the first-order equations saturating it. We solve these first-order equations numerically by means of the finite-difference scheme, therefore obtaining regular solutions of the effective model, their energy being quantized according the winding number rotulating the final configurations, as expected. We depict the numerical solutions, whilst commenting on the main properties they engender.Comment: 8 pages, 9 figure

TMbarrier: speculative barriers using hardware transactional memory

Barrier is a very common synchronization method used in parallel programming. Barriers are used typically to enforce a partial thread execution order, since there may be dependences between code sections before and after the barrier. This work proposes TMbarrier, a new design of a barrier intended to be used in transactional applications. TMbarrier allows threads to continue executing speculatively after the barrier assuming that there are not dependences with safe threads that have not yet reached the barrier. Our design leverages transactional memory (TM) (specifically, the implementation offered by the IBM POWER8 processor) to hold the speculative updates and to detect possible conflicts between speculative and safe threads. Despite the limitations of the best-effort hardware TM implementation present in current processors, experiments show a reduction in wasted time due to synchronization compared to standard barriers.Universidad de Málaga.

Digital literacy in early childhood

99 páginas incluye diagramas.Este proyecto está encaminado a investigar cómo mejorar la habilidad oral y las sub-habilidades por medio del alfabetismo digital en estudiantes jóvenes. La población escogida para desarrollar este proyecto fue un grupo de primer grado del colegio corazonista de Bogotá conformado por 39 estudiantes de edades entre los seis y siete años. El principal objetivo de esta investigación es determinar el posible impacto de la tecnología de la información y la comunicación (TIC) para superar las dificultades que tienen los estudiantes de primer grado cuando expresan acciones progresivas de manera oral. Para lograr este objetivo fueron creadas algunas estrategias basadas en las habilidades de la alfabetización digital que los estudiantes adquirieron mientras mejoraban sus habilidades y sub habilidades del habla utilizando diferentes herramientas digitales y ambientes virtuales que los motivaron a ser comprometidos con las actividades y rutinas de estudio y nuevos escenarios de aprendizaje. Por consiguiente, estos estudiantes podrían crear estrategias que los iniciaran en el proceso de ser estudiantes auto-regulados. Como resultado, los estudiantes demostraron que a su edad es posible crear rutinas que mejoren los procesos de aprendizaje de la lengua. Se encontró también que los estudiantes disfrutaban y aprovechaban el componente tecnológico; el cual permitió considerablemente, que mejorará la habilidad de comunicarse de manera oral. Además, la creación de rutinas de aprendizaje basadas en los principios de la auto-regulación fueron apropiadas para que los niños empezaran a implementarlas también en su vida diaria.

Galaxy Formation in the Lambda-Cold Dark Matter Cosmology

In this thesis I explore the effects of the various physical processes behind galaxy formation and evolution in hierarchical cosmologies by using semi-analytical modelling. I use the Durham semi-analytical model GALFORM. I first test the GALFORM model predictions using observations from the Sloan Digital Sky Survey (SDSS). I use two different variants of the model, Baugh et al (2005), which assumes a top-heavy initial mass function (IMF) in starbursts and superwind feedback, and Bower et al (2006), which incorporates AGN feedback with a standard IMF. I compare the luminosity function, colours, sizes and morphology distributions of present-day galaxies in the models and with the SDSS. The Bower et al model better reproduces the shape of the luminosity function, the morphology-luminosity relation and the colour bimodality observed in the SDSS data. The Baugh et al model is much more successful at predicting galaxy sizes for late-type galaxies. Both models have problems with the sizes of early-type galaxies, which are predicted to be too large for low luminosities and too small for high luminosities compared to SDSS. I tested the impact on the model predictions of varying the prescriptions for supernova feedback, disk instabilities and galaxy mergers. In the second part of the thesis I explore the connection between two high redshift star-forming galaxy populations and present-day galaxies and their contribution to the star formation history. I built galaxy merger trees and followed the evolution and properties of submillimetre galaxies (SMGs) and Lyman-break galaxies (LBGs) using the Baugh et al (2005) model. The model predicts that the descendants of SMGs (S_{nu} > 5 mJy) have a median stellar mass of ~10e11/h solar masses, and that more than 70% of these descendants are bulge-dominated. More than 50% of present-day galaxies with stellar masses larger than 7 x 10e11/h solar masses are predicted to be descendants of such SMGs. Somewhat controversially, the stellar mass produced in the submillimetre phase contributes only 0.2% of the total present-day stellar mass, and 2% of the stellar mass of SMG descendants. The descendants of z=3 LBGs are predicted to have a median stellar mass equal to that of the Milky Way (M = 4 x 10e10/h solar masses), while the descendants of z=6 LBGs are predicted to have a larger median stellar mass (M = 10e11/h solar masses). The model predicts that only one in every 16 and one in every 50 Milky Way mass galaxies have a Lyman-break galaxy progenitor at z=3 and z=6 respectively
