DESCRIPTION:Title: Nonpositive Towers in Contractible 3-Manifold Spines\n	\n
 	Abstract: The nonpositive immersions property (NPI) and nonpositive towers
  property (NPT) are motivated via Whitehead’s asphericity conjecture\, and
  a class of 2-complexes failing to have NPI is shown to still have NPT.\n
