DESCRIPTION:Eleni Katifori\, Department of Physics and Astronomy\, Universi
 ty of Pennsylvania\n\nHost: Itai Cohen\n\nSelf-organization in living flow
  networks\n\nComplex life larger than a humble nematode would not be possi
 ble without a circulatory system. Plants\, fungi\, and animals have develo
 ped vascular systems of striking complexity to solve problems of long dist
 ance nutrient delivery\, waste removal\, and information exchange. These d
 isparate vascular systems are constrained by the same physics and their st
 ructure is governed by the common universal principles such as a hierarchy
  in the vessel diameters and the existence of multiple loops. Typically\, 
 biological transport networks have to satisfy competing demands to operate
  efficiently and robustly while confronted with an ever-changing environme
 nt. The architecture of these networks\, as defined by the topology and ed
 ge weights\, determines how efficiently the networks perform their functio
 n.\n\nIn this talk we present several examples that highlight how\, in bot
 h plants and animals\, the circulatory networks self-organize in order to 
 optimally achieve their intended function\, such as delivering fluid and n
 utrients to the tissue efficiently and homogeneously. This network remodel
 ing and self-organization takes place using only local information (each v
 essel only remodels based on mechanical or other local cues) in order to a
 chieve or improve on the collective performance of the network in issues l
 ike dissipation or nutrient delivery. We consider theoretical models that 
 describe such remodeling\, and discuss how these models can provide inspir
 ation for the design of functional artificial microvasculature and other e
 ngineering applications.\n\nPoster
