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

open access: yesPediatric 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.

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

open access: yesIEEE 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 ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

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

open access: yesIEEE 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.

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

open access: yesНаучно-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
