20 kW Monolithic Fiber Amplifier With Directly Dual-Wavelength Laser Diodes Counter Pumping

IEEE Photonics Journal
In this study, we demonstrate a high-power ytterbium-doped fiber laser (YDFL) based on laser diodes (LDs) directly pumping scheme. Tandem pumping and LD direct pumping are two common schemes for generating high-brightness laser output in YDFL.

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.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
