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 […]

Recent empirical work has provided new insight into the origins of distributive, procedural, and retributive justice. Engelmann and Tomasello [1] offer an overarching framework that attempts to explain these different aspects of fairness as deriving from a single core process – a desire for mutual respect. While we applaud this integrative attempt, we point out […]
