Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Experimental study of the asymmetry of a three-phase stress system [PDF]

Научно-технический вестник Брянского государственного университета, 2018
“Arduino” allows the computer to simulate the electrical load. Devices using “Arduino” receive sensor information and control the actuators. The platform, with software code, is built on a simple board with a modern environment for writing software. This

Electronic Load System With Interleaved Structure Applicable to DC, Single-Phase AC, and Three-Phase AC

IEEE Access, 2022
We propose an electronic load system with an interleaved structure applicable to DC, single-phase AC, and three-phase AC. Applying the interleaved method makes it possible to reduce voltage and current ripple, thereby reducing voltage and current stress ...

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

Reduced Reference Frame Transformation Assessment in Unbalanced Three-Phase Four-Wire Systems

IEEE Access, 2023
Three-phase four-wire systems require a reference frame similar to that used in 3-phase 3-wire system configurations that allow them to be easily analysed, modelled and controlled.

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Topology Optimization Analysis of Leakage Current Suppression in Three-Level Four-Leg Photovoltaic Grid-Connected Inverter

IEEE Access, 2023
The grid-connected non-isolated photovoltaic inverter system suffers from the leakage current, which increases the loss of the system, and the grid-connected current harmonics impact the normal operation of the equipment.
