Lá fora um lugar para existir/Abroad a place where to exist

A exposição “Artistas Portugueses - Lá Fora” pretende mostrar uma parte significativa da produção de artes plásticas que resultou de processos de migração que tiveram origem em território português. Integra uma multiplicidade de situações temporais e sociais que, para serem lidas, necessitam de alguma contextualização. Trata-se, tal como no caso da emigração económica, de uma emigração de sobrevivência, sendo que aqui o sentido do termo sobrevivência assume uma dimensão mais existencial. Para elas, partir quer dizer, ao mesmo tempo, resistir enquanto ser humano e existir enquanto criador. The exhibition “ABROAD” aims to show a significant part of the Fine Arts production resulting from migration procedures starting from the Portuguese territory. It comprises multiple periods of time and social situations which, in order to be comprehended, need to be contextualized. This is, just like in the case of economic emigration, an emigration for survival even if in this context the meaning of the Word survival assumes an existential dimension. For those people to leave means, simultaneously, to resist as a human being and to exist as a creator.

Diffusional kurtosis imaging using a fast heuristic constrained linear least squares algorithm: a plugin for OsiriX

Diffusion Kurtosis Imaging (DKI) is a fairly new magnetic resonance imag-ing (MRI) technique that tackles the non-gaussian motion of water in biological tissues by taking into account the restrictions imposed by tissue microstructure, which are not considered in Diffusion Tensor Imaging (DTI), where the water diffusion is considered purely gaussian. As a result DKI provides more accurate information on biological structures and is able to detect important abnormalities which are not visible in standard DTI analysis. This work regards the development of a tool for DKI computation to be implemented as an OsiriX plugin. Thus, as OsiriX runs under Mac OS X, the pro-gram is written in Objective-C and also makes use of Apple’s Cocoa framework. The whole program is developed in the Xcode integrated development environ-ment (IDE). The plugin implements a fast heuristic constrained linear least squares al-gorithm (CLLS-H) for estimating the diffusion and kurtosis tensors, and offers the user the possibility to choose which maps are to be generated for not only standard DTI quantities such as Mean Diffusion (MD), Radial Diffusion (RD), Axial Diffusion (AD) and Fractional Anisotropy (FA), but also DKI metrics, Mean Kurtosis (MK), Radial Kurtosis (RK) and Axial Kurtosis (AK).The plugin was subjected to both a qualitative and a semi-quantitative analysis which yielded convincing results. A more accurate validation pro-cess is still being developed, after which, and with some few minor adjust-ments the plugin shall become a valid option for DKI computation
