CD1a and antitumour immune response

2004

Primary immune response is based on the capacity of local professional antigen-presenting cells (whose prototype is represented by dendritic cells, DCs) to take up and present antigens to selected clones of T cells, but also to non-specific effector cells such as macrophages or natural killer cells. The four CD1 proteins, all of which share a limited homology to class I MHC proteins, are differently expressed in various cell types, of both mesenchymal and, as recently described, epithelial lineage. Regarding the role of CD1 molecules in the anti-tumour response, it has been reported that CD1+ dendritic cells are involved in the first steps of the primary immune response in a number of malig…

Morphological priming involves more than orthographic priming

2007

Los resultados de investigaciones recientes en reconocimiento visual de palabras apoyan cierta autonomía de las unidades morfológicas. Con el fin de investigar si los efectos de priming morfológico están producidos más por el solapamiento de forma que por las relaciones morfológicas de las palabras, se presenta un experimento de decisión léxica con priming enmascarado. Se comparan, mediante la utilización de las mismas palabras test (NUEVO), dos condiciones experimentales relativas a relaciones netamente ortográficas (nueve) y a relaciones morfológicas basadas en la marca de género (nueva). Los resultados de este estudio muestran que las palabras precedidas por otras con las que comparten u…

Percorsi relazionali nelle comunità. Minori, buone prassi e rappresentazioni a confronto.

2014

The aim of this thesis was to analyze the context of residential communities for young offenders (Part I) and to analyze the influence of social representations in adolescents and educators (Part II). The first part offers two levels of study on adolescents and on the organizational structure of the community. Adolescents show many problematic levels in the identified variables (Experiences of neglect and abuse during childhood, Attachment Styles, Self-Esteem, Interpersonal Relations, Behavioural problems). No differences between groups of young differentiating according to the reason for placement in community were found. Analysis of community (101 educators from 20 different households) w…

Address Event Representation (AER) approach to resistive sensor arrays

2020

Address event representation (AER) has become an excellent strategy when approaching traditional frame based applications, mainly vision sensors. In this paper, and Within this scope, the potential of the AER paradigm is demonstrated when considering resistive (non-vision) sensor arrays. For showing quantitative evidences, MOS AMS 0.35 μm versions of some of the circuit cells typically used in AER systems, such as Winner-Take-All (WTA) circuits, have been implemented and analyzed. In these unit-cells, basic resistance-controlled sources are considered as per sensing devices. Preliminary simulation results demonstrate that this approach is valid for a wide range of resistive sensors.

Representations of war in francophone literary space : the cas of the Horn of Africa

2017

The war is an experience that, by its commotion, condemned to unspeakable. It forces writers to define the relationship they have with the language they practices when it does not metamorphose themselves. It is this sense that need dealing with the range of transgressions at work in the war story which, through formal and language disorders distortions that contribute to its development, inaugurates writing that escapes definitions categorizations. Instead of reporting on the disaster, the literary imagination is in an external object, searching the paradoxical experience aestheticisation a priori ineffable a way around the impotence of language to express the inexpressible. Nevertheless, h…

Barriers to open e-learning in public administrations

2016

Abstract This article presents a comparative study of the barriers to open e-learning in public administrations in Luxembourg, Germany, Montenegro and Ireland. It discusses the current state of open e-learning of public administration employees at the local government level and derives the barriers to such learning. This paper's main contribution is its presentation of an empirical set of barriers in the four European countries. The results allow informed assumptions about which barriers will arise in the forthcoming use of open-source e-learning technology, particularly open educational resources as means of learning. Furthermore, this study offers a contextualised barrier framework that a…

Deformation quantization of non regular orbits of compact Lie groups

2001

In this paper we construct a deformation quantization of the algebra of polynomials of an arbitrary (regular and non regular) coadjoint orbit of a compact semisimple Lie group. The deformed algebra is given as a quotient of the enveloping algebra by a suitable ideal.

Clustering techniques for personal photo album management

2009

In this work we propose a novel approach for the automatic representation of pictures achieving at more effective organization of personal photo albums. Images are analyzed and described in multiple representation spaces, namely, faces, background and time of capture. Faces are automatically detected, rectified and represented projecting the face itself in a common low-dimensional eigenspace. Backgrounds are represented with low-level visual features based on RGB histogram and Gabor filter bank. Faces, time and background information of each image in the collection is automatically organized using a mean-shift clustering technique. Given the particular domain of personal photo libraries, wh…

Gitanas without a tambourine: Notes on the historical representation and personal self-representation of the Spanish Romani woman.

2020

The performative representation of the Spanish Roma woman reveals a historical journey that brings her closer to many symbolic elaborations of the feminine, giving her a special affinity with the imaginary concerning the colonized woman, particularly with the Orientalist vision. Developed initially by the travelling intellectuals in Spain who sought a fusion of the topics of sexualized exoticism, the myth was reworked by local artists and thinkers without undermining their power to silence and make invisible the reality of the most vulnerable and most represented members of the ethnic group, their women. Today, a growing awareness of the importance of collective action directs Roma women t…
