  • Reentry and ectopic pacemakers emerge in a three-dimensional model for a slab of cardiac tissue with diffuse microfibrosis near the percolation threshold 

    Alonso Muñoz, Sergio; Weber dos Santos, Rodrigo; Bär, Markus (2016-11-22)
    Article
    Accés obert
    Arrhythmias in cardiac tissue are generally associated with irregular electrical wave propagation in the heart. Cardiac tissue is formed by a discrete cell network, which is often heterogeneous. Recently, it was shown in ...
  • Neutron-induced Fission Cross Section of240,242Pu 

    Salvador Castiñeira, P.; Brys, Tomasz; Eykens, Roger; Hambsch, Franz Josef; Gook, A.; Oberstedt, Stephan; Pretel Sánchez, Carme; Sibbens, Geodele; Vanleeuw, David; Vidali, Marzio (2015)

    Text en actes de congrés
    Accés obert
    Diffusion and scaling of the velocity and vorticity in a thermoelectric driven heating and cooling experimental device is presented in order to map the different patterns and transitions between two and three dimensional ...
  • Numerical analysis of conservative unstructured discretisations for low Mach flows 

    Ventosa Molina, Jordi; Chiva Segura, Jorge; Lehmkuhl, Oriol; Muela Castro, Jordi; Pérez Segarra, Carlos David; Oliva Llena, Asensio (2016-12-01)
    Article
    Accés restringit per política de l'editorial
    Unstructured meshes allow easily representing complex geometries and to refine in regions of interest without adding control volumes in unnecessary regions. However, numerical schemes used on unstructured grids have to ...
  • Analysis of noise-induced temporal correlations in neuronal spike sequences 

    Reinoso, Jose A.; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina (2016-11-01)
    Article
    Accés restringit per política de l'editorial
    We investigate temporal correlations in sequences of noise-induced neuronal spikes, using a symbolic method of time-series analysis. We focus on the sequence of time-intervals between consecutive spikes (inter-spike-intervals, ...
  • Validation of semi-quantitative methods for DAT SPECT: influence of anatomical variability and partial volume effect 

    Gallego, J.; Niñerola-Baizán, A.; Cot, A.; Sempau Roma, Josep (2015)
    Article
    Accés restringit per política de l'editorial
    The aim of this work was to evaluate the influence of anatomical variability between subjects and of the partial volume effect (PVE) on the standardized Specific Uptake Ratio (SUR) in [123I]FP-bib SPECT studies. To this ...
  • Synthesis of C-rich dust in CO nova outbursts 

    José Pont, Jordi; Halabi, Ghina M.; El Eid, MounibF. (2016-09)
    Article
    Accés obert
    Context. Classical novae are thermonuclear explosions that take place in the envelopes of accreting white dwarfs in stellar binary systems. The material transferred onto the white dwarf piles up under degenerate conditions, ...
  • Solid state physicochemical properties and applications of organic and metallo-organic fullerene derivatives 

    Mitsari, Efstratia; Romanini, Michela; Manesh, Zachariah; Macovez, Roberto (2016)
    Article
    Accés obert
    We review the fundamental properties and main applications of organic derivatives and complexes of fullerenes in the solid-state form. We address in particular the structural properties, in terms of crystal structure, ...
