The Role of Chemotherapy in Pediatric Myoepithelial Carcinoma: A Systematic Review of the Literature

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Myoepithelial carcinoma (MEC) in pediatric patients is a rare and aggressive malignancy characterized by heterogeneous morphology and variable molecular features. The optimal role of chemotherapy remains unclear. We conducted a systematic review according to PRISMA 2020 guidelines to evaluate chemotherapy in pediatric and young‐adult patients ...

Voltage stability indexes for contingencies ranking [PDF]

, 2011
Different stability indexes and contingencies ranking methods have been proposed in order to study this phenomenon. There are physical indexes, which use the net characteristics. In this paper, we compare some of these methodologies, focusing on those for stability studies.
