DESCRIPTION:Speaker: Aondoyima Gerald Ioratim-Uba\nhosted by Andela Saric\n
 Abstract: Convergence extension\, the simultaneous elongation of tissue al
 ong one axis while narrowing along a perpendicular axis\, occurs during em
 bryonic development. It is a fundamental process that contributes to shapi
 ng the organism and it happens in many different species and tissue types.
  I will present a minimal continuum model\, that can be directly linked to
  the controlling microscopic biochemistry\, which shows spontaneous conver
 gence extension. It is comprised of a 2D viscoelastic active material with
  a mechano-chemical active feedback mechanism coupled to a substrate via f
 riction. Robust convergent extension behaviour emerges beyond a critical v
 alue of the activity parameter and is controlled by the boundary condition
 s and the coupling to the substrate. Oscillations and spatial patterns als
 o emerge in this model when internal dissipation dominates over friction\,
  as well as in the active elastic limit.
