This paper proposes a fast algorithm, called the SpiralFFT, that computes samples of the 3-D discrete Fourier transform of an object of interest along spiral contours in frequency space. This type of sampling geometry is prevalent in 3-D magnetic resonance imaging, as spiral sampling patterns allow for rapid, uninterrupted scanning over a large range of frequencies. We show that parameterizing ...

The Embodied Cognition Framework maintains that understanding actions requires motor simulations subserved in part by premotor and primary motor regions. This hypothesis predicts that disturbances to these regions should impair comprehension of action verbs but not non-action verbs. We evaluated the performances of 10 patients with Parkinson's disease (PD) and 10 normal comparison (NC) particip...

We present morphological analyses of verb inflections produced by 15 Spanish-speaking children (age range: 1;7 to 4;7) taken from longitudinal and cross-sectional samples of spontaneous speech and narratives. Our main observation is the existence of a dissociation between regular and irregular processes in the distribution of errors: regular suffixes and unmarked (non-alternating) stems are ove...

Understanding which verb argument structure (VAS) features (if any) are part of verbs' lexical entries and under which conditions they are accessed provides information on the nature of lexical representations and sentence construction. We investigated neural and behavioral effects of three understudied VAS characteristics (number of subcategorization options, number of thematic options and ove...

The resulting denominal verb (DV) has the full syntactic and morphological distribution of any verb in West Greenlandic. It also retains some of the properties of the incorporated nominal, which has led some researchers to analyze this construction as a kind of NI. However, as Sapir (1911), Mithun (1986) and others have argued, it has little in common with NI constructions in languages like Moh...

The translation of English phrasal verbs (PVs) into French is a challenge, specially when the verb occurs apart from the particle. Our goal is to quantify how well current SMT paradigms can translate split PVs into French. We compare two inhouse SMT systems, phrase-based and hierarchical, in translating a test set of PVs. Our analysis is based on a carefully designed evaluation protocol for ass...
