BIOCOM-SC - Grup de Biologia Computacional i Sistemes Complexos

 

El grup de recerca BIOCOM-SC aspira a crear sinergies de manera que els coneixements de física bàsica (fluids, materials, sistemes complexos) s’utilitzin per abordar problemes en biociència, des d’aquells d’interès en biomedicina (dinàmica d’ones elèctriques al cor, xarxes neuronals, tuberculosi) a d’altres d’enginyeria de sistemes biològics (simulació de sistemes microbians d’interès agroalimentari i medi ambiental). Per assolir aquest objectiu comptem amb un grup interdisciplinari on a més de físics hi ha matemàtics, enginyers i biòlegs, en col·laboració amb grups de biologia experimental de dins i fora de Catalunya. L’objectiu final és esdevenir un grup de referència en biologia teòrica i computacional capaç de fer el salt des de les idees de física fonamental a problemes d’interès biosanitari o mediambiental.

The group studies out-of-equilibrium systems by means of nonlinear dynamics techniques and their application to the self-organisation of complex systems, spatiotemporal pattern formation, biophysical systems, materials science, nanometric devices, studies and measurements in architectural and environmental acoustics and energetic efficiency in buildings.

  • Stochastic coupled map model of subcellular calcium cycling in cardiac cells 

    Romero Castañeda, Luis; Álvarez Lacalle, Enrique; Shiferaw, Yohannes (Institute of Physics (IOP), 2019-02-01)
    Article
    Restricted access - publisher's policy
    In this study, we analyze a nonlinear map model of intracellular calcium (Ca) and voltage in cardiac cells. In this model, Ca release from the sarcoplasmic reticulum (SR) occurs at spatially distributed dyadic junctions ...

  • Stability of oscillating hexagons in rotating convection 

    Echebarría Domínguez, Blas; Riecke, Hermann (2000)
    Article
    Open Access
    Breaking the chiral symmetry, rotation induces a secondary Hopf bifurcation in weakly nonlinear hexagon patterns which gives rise to oscillating hexagons. We study the stability of the oscillating hexagons using three ...

    Echebarría Domínguez, Blas; Riecke, Hermann (2001)
    Article

    Quasipatterns have been found in dissipative systems ranging from Faraday waves in vertically vibrated fluid layers to nonlinear optics. We describe the dynamics of octagonal, decagonal and dodecagonal quasipatterns by ...

  • Spatiotemporal control of cardiac alternans 

    Echebarría Domínguez, Blas; Karma, Alain (Institute of Physics (IOP), 2002)
    Article
    Restricted access - publisher's policy
    Electrical alternans are believed to be linked to the onset of life-threatening ventricular arrhythmias and sudden cardiac death. Recent studies have shown that alternans can be suppressed temporally by dynamic feedback ...

    Conference lecture
    Open Access
    Among the different potassium channels present in cardiac myocytes, the small conductance Ca2+ activated potassium channels (SK channels) are particular because they are affected by changes in intracellular calcium. The ...

    Marchena Angos, Miquel; Echebarría Domínguez, Blas (2018-12-10)
    Article
    Open Access
    In cardiac cells, calcium is the mediator of excitation-contraction coupling. Dysfunctions in calcium handling have been identified as the origin of some cardiac arrhythmias. In the particular case of atrial myocytes, ...
