DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MoRN/110/">N
 ecessary conditions for non-monotonic steady state response</a>\nby Polly 
 Yu (University of Illinois Urbana-Champaign) as part of Seminar on the Mat
 hematics of Reaction Networks\n\n\nAbstract\nNon-monotonic (or "biphasic")
  dose responses are often observed in experimental biology\, which raises 
 the question of which network motifs might underlie such behaviours. It is
  well known that the presence of an incoherent feedforward loop (IFFL) may
  give rise to a non-monotonic response\, and it has been informally conjec
 tured that this condition is also necessary. We disprove this conjecture w
 ith an example. Moreover\, we show that a version of the conjecture does h
 old. Towards this aim\, we consider several related notions (infinitesimal
  homeostasis\, biphasic response\, and stable biphasic response) and their
  underlying network motifs.\n
