DESCRIPTION:SPEAKER:  Lisa Manning  (Syracuse University)\n\nTITLE:    What
  do guitar strings and ballons have in common with biological networks and
  tissues?\n\nABSTRACT:\n\nBoth guitar strings and balloons are floppy unle
 ss rigidified by geometrically induced pre-stresses.  The same kind of pre
 stress-induced rigidity transition in under-constrained materials has more
  recently been discussed in the context of disordered biopolymer networks 
 and models for biological tissues.  Here\, we propose a general approach t
 o quantitatively describe such transitions.  Based on a minimal length fun
 ction\, which scales linearly with intrinsic fluctuations in the system an
 d quadratically with shear strain\, we make concrete predictions about the
  elastic response of these materials\, which we verify numerically and whi
 ch are consistent with previous experiments.  Finally\, our approach may p
 rovide a gateway towards connecting macroscopic elastic properties of diso
 rdered materials to their microscopic structure.
