• Attention mechanisms and the mosaic evolution of speech

  Martins, Pedro; Boeckx, Cedric (Frontiers, 2014)

  There is still no categorical answer as to why humans, and no other species, have speech, or why speech is the way it is. Several purely anatomical arguments have been put forward, but they have been shown to be false, ...
• Intra-aneurysmal pressure and flow changes induced by flow diverters: relation to aneurysm size and shape

  Larrabide, Ignacio, 1978-; Aguilar, María Laura; Morales, Hernán G.; Geers, Adrianus Johannes; Kulcsár, Zsolt; Rüfenacht, Daniel; Frangi Caregnato, Alejandro (American Society of Neuroradiology, 2013)

• Protective role of false tendon in subjects with left bundle branch block: a virtual population study

  Lange, Matthias; Di Marco, LY; Lekadir, Karim, 1977-; Lassila, Toni; Frangi Caregnato, Alejandro (Public Library of Science (PLoS), 2016)

  False tendons (FTs) are fibrous or fibromuscular bands that can be found in both the normal and abnormal human heart in various anatomical forms depending on their attachment points, tissue types, and geometrical properties. ...
• How? Why? What? Where? When? Who? Grounding ontology in the actions of a situated social agent

  Lallée, Stéphane; Verschure, Paul F. M. J. (MDPI, 2015)

  Robotic agents are spreading, incarnated as embodied entities, exploring the tangible world and interacting with us, or as virtual agents crawling over the web, parsing and generating data. In both cases, they require: (i) ...
