Impact of Initial Treatment Setting on Survival in Relapsed Pediatric and AYA Bone Sarcomas: A Secondary Analysis of a Prospective Clinical Trial

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Outcomes in relapsed or refractory pediatric and AYA bone sarcomas remain poor, and the impact of early referral to specialized sarcoma centers on survival is unclear. Early centralization of care may improve local and systemic treatment quality, but evidence in this population is limited.

On the PI index of some nanotubes

Journal of Physics: Conference Series, 2006
The PI index is a graph invariant defined as the summation of the sums of edges of neu and nev over all the edges of connected graph G, where neu is the number of edges of G lying closer to u than to v and nev is the number of edges of G lying closer to v than to u.

Vertex PI index of V-phenylenic nanotubes and nanotori [PDF]

, 2009
In series of papers, P.V. Khadikar introduced a new topological index and named it as Padmakar-Ivan (PI) Index. This index is found very useful in nano technology, particularly in making and characterizing carbon nanotubes and nanotori. In this paper the
