A wide range and high speed automatic gain control [PDF]
Proceedings of International Conference on Particle Accelerators, 2002 Automatic gain control (AGC) techniques have been largely used since the beginning of electronics but in most of the applications the dynamic response is slow compared with the carrier frequency. The problem of developing an automatic gain control having simultaneously high dynamic response and wide control range is analyzed in this work. An ideal gain

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes
Pediatric Blood &Cancer, EarlyView.ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.
