Arterial input function (AIF) is estimated from perfusion images as a basic curve for the calculus of hemodynamic variables used as surrogate markers of the vascular status of tissues. However, at present, identification of AIF is made manually leading by prior knowledge. We propose an automatic estimation of AIF in perfusion images, which is based […]

The analysis of Electroencephalographic (EEG) signals is of ulterior importance to aid in the diagnosis of mental disease and to increase our understanding of the brain. Traditionally, clinical EEG has been analyzed in terms of temporal waveforms, looking at rhythms in spontaneous activity, subjectively identifying troughs and peaks in Event-Related Potentials (ERP), or by studying […]

Yet, in situations of procedural fairness, when an unequal distribution results from an impartial procedure, children deem that result fair – even if they end up being personally disadvantaged.
