A unified framework for co-optimization of PFR and FFR reserves using linearized tri-criteria frequency constraints

International Journal of Electrical Power & Energy Systems
The increasing penetration of inverter-based resources reduces system inertia and heightens concerns about frequency stability. This paper proposes a systematic methodology for jointly optimizing primary frequency response (PFR) and fast frequency ...

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.

Phase Angle as an Early Functional Biomarker of Cancer‐Related Fatigue in Pediatric Oncology: A Prospective Longitudinal Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric cancer remains a leading cause of morbidity and mortality worldwide, particularly in low‐and middle‐income countries. Cancer treatment may impair nutritional status, alter body composition, and exacerbate cancer‐related fatigue (CRF).
