Mathematical Biophysics seminars

The NOLIN Lab together with professors from the mathematical department of the UPC interested on mathematical Biology organize regular informal seminars.  

The seminars take place usually in the room 0.6 of the EPSEB.

  • 9/3/2018 (12:30) Dafni Giannari (University of Pratas): The effect of brain geometry on magnetoencephalographic measurements

Abstract: The human brain is an extremely complex organ for which the knowledge we have so far is minimal. This complexity is due to the vast number of nerve cells it contains. The brain neurons compose an enormous electric circuit in which ionic currents of biochemical origin flow. The presence of primary and induced electric currents in stimulated areas within the brain, leads to the generation of an electromagnetic field that can be detected externally. In particular, the weak external magnetic field is measured by the Magnetoencephalog­raphy method. In the present talk, the brain, together with the scull which surrounds it, is considered as a single, homogeneous and isotropic conductor, while the source of the externally measured electromagnetic field is modeled as a single dipole located at a specific point in­side the conductor. At this point it is noted that the size of the human brain and the values of the physical parameters describing the propagation of the electromagnetic wave within the brain, allow the use of the quasi – static theory of Maxwell’ s equations to describe the propagation of the electromagnetic field, that is generated by the brain’s function.


  • 23/3/2018 (12:30) Ramón Planet (Universitat de Barcerlona): Two-phase displacements in a gap-modulated Hele-Shaw cell

Abstract: Two-phase displacements into a porous media are characterized by complex dynamics composed by different pore-scale events. This events can be divided into two categories: (i) smooth and reversible displacements, and (ii) abrupt displacements (e.g. Haines jumps). This discontinuity of pore invasion is the origin of the hysteretic behaviour of flows in porous media. This is a consequence of irreversibility and multistability. The problem of hysteresis in porous medium is an old an unresolved question in hydrology and soil physics. Most of the attempts to give an explanation are based on phenomenological models without physical basis. We present a simple model that describes both the irreversible and the reversible motion of fluid into a single “pore” in a disordered media. This model is based on physical principles, an advantage over the current phenomenological models commonly used. Predictions made with this model are also presented to show its validity in the range of parameters explored.
