Improved Outcomes for Older Children, Adolescents, and Young Adults With Neuroblastoma in the Post‐Immunotherapy Era: An Updated Report From the International Neuroblastoma Risk Group

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background We describe clinical and biologic characteristics of neuroblastoma in older children, adolescents, and young adults (OCAYA); describe survival outcomes in the post‐immunotherapy era; and identify if there is an age cut‐off that best discriminates outcomes.

On interconnections of infinite-dimensional port-Hamiltonian systems [PDF]

open access: yes, 2004
Network modeling of complex physical systems leads to a class of nonlinear systems called port-Hamiltonian systems, which are defined with respect to a Dirac structure (a geometric structure which formalizes the power-conserving interconnection structure

Phenomenological Model of Electrotechnical Systems Based on a Synchronous Generator With an Excitation System

open access: yesModelling and Simulation in Engineering
We propose a variant of the application of a phenomenological approach using the “black box” concept to the modeling of electrotechnical systems. The method enables obtaining simplified models of a complex electrotechnical system based on a synchronous ...
