Communication and Language Profiles of Children Treated for Posterior Fossa Brain Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cognitive and language deficits are frequently reported sequelae of posterior fossa brain tumors (PFBT). Typically, delayed onset impedes prompt assessment and early intervention. This has devastating implications for quality of life.

Ultra high gain step up DC/DC converter based on switched inductor and improved voltage lift technique for high‐voltage applications

IET Power Electronics, 2022
Voltage lift is a well‐known technique to improve the voltage gain of the converter. A combination of switched inductor and the conventional voltage lift technique can be used to achieve high gain, but the semiconductor's stress is still high.

CMOS high-frequency rectifierwith unity voltage gain

Electronics Letters, 1995
A new CMOS voltage rectifier circuit based on the current mode technique is presented. The circuit exhibits highly linear characteristics over a wide range of input values. It is extremely simple and compact, and a very effective building block for VLSI analogue IC design. SPICE simulated results are given, in good agreement with theoretical results.

Stressful Events Reported by Childhood Cancer Survivors and Community Controls From the St. Jude Lifetime (SJLIFE) Cohort: A Mixed Method Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.
