      Cinelli, Ilaria; Destrade, Michel; Duffy, Maeve; McHugh, Peter (Wiley, 2017-11-21)
      Traumatic brain injuries and damage are major causes of death and disability. We propose a 3D fully coupled electro-mechanical model of a nerve bundle to investigate the electrophysiological impairments due to trauma at ...

      Du, Yangkun; Su, Yipin; Lü, Chaofeng; Chen, Weiqiu; Destrade, Michel (Elsevier, 2020-07-01)
      Several experiments have demonstrated the existence of an electro-mechanical effect in many biological tissues and hydrogels, and its actual influence on growth, migration, and pattern formation. Here, to model these ...
    • Electrostatically tunable axisymmetric vibrations of soft electro-active tubes 

      Zhu, Fangzhou; Wu, Bin; Destrade, Michel; Chen, Weiqiu (Elsevier, 2020-05-28)
      Due to their unique electromechanical coupling properties, soft electro-active (SEA) resonators are actively tunable, extremely suitable, and practically important for designing the next-generation acoustic and vibration ...

      Cinelli, Ilaria; Destrade, Michel; Duffy, Maeve; McHugh, Peter (Institute of Electrical and Electronics Engineers, 2017-09-14)
      Objective: We propose a novel approach for modelling the interdependence of electrical and mechanical phenomena in nervous cells, by using electrothermal equivalences in finite element (FE) analysis so that existing ...
    • EndoCOM : Conception d un banc in vitro de simulation des anévrismes de l aorte abdominale 

      Destrade, Michel (2009)
      (FR) Le traitement des anévrismes de l'aorte abdominale par voie endovasculaire est aujourd'hui prédominant à plus de 65 % mais comporte encore des risques. Le suivi postopératoire devient alors crucial. Le projet de ...
    • ENDOCOM: Abdominal aortic aneurysm test bench for in vitro simulation 

      Destrade, Michel (IEEE, 2007)
      An abdominal aortic aneurysm (AAA) is a dilatation of the aorta at the abdominal level, whose rupture is a life threatening complication. Recent treatment procedures of AAA consists in endovascular treatment with covered ...
    • Estimating average attributable fractions with confidence intervals for cohort and case control studies 

      Ferguson, John; Alvarez-Iglesias, Alberto; Newell, John; Hinde, John; O’Donnell, Martin (SAGE Publications, 2016-06-24)
      Chronic diseases tend to depend on a large number of risk factors, both environmental and genetic. Average attributable fractions were introduced by Eide and Gefeller as a way of partitioning overall disease burden into ...
    • Exceptional Vertex Operator Algebras and the Virasoro Algebra 

      Tuite, Michael P. (2008)

    • Explicit secular equation for Scholte waves over a monoclinic crystal 

      Destrade, Michel (Elsevier, 2004)
