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).

Time to Diagnosis Among Children and Adolescents With Cancer in Québec, Canada: A Population‐Based Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Timely cancer diagnosis in children and adolescents is important to improving outcomes. We aimed to quantify time to diagnosis and assess variations by patient, demographic and system‐level factors. Procedure We conducted a population‐based study of individuals aged 0–19 years diagnosed with one of 12 cancers from 2010 to 2022 in ...

Impact of Japan's 2024 Physician Work‐Style Reform on Pediatric Hematology–Oncology: Educational Implications in a 2‐Year Survey

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Japan's 2024 physician work‐style reform introduced legally binding limits on physicians’ working hours, but its impact on education and workforce sustainability in pediatric hematology–oncology (PHO) remains unclear. Procedure We conducted a repeated cross‐sectional study with structured quantitative items and free‐text responses ...

Mitigating the impacts of geomagnetic disturbances on the small signal stability

International Journal of Electrical Power & Energy Systems
Geomagnetically induced currents (GICs) caused by geomagnetic disturbances (GMDs) flow through the transformers, which lead to the increase of reactive power loss (QGIC). As reactive loads added to the system, QGIC causes the change of power flow distribution, which connects GMDs with small signal stability.

Small-signal stability analysis of neutral delay differential equations [PDF]

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
This paper focuses on the small-signal stability analysis of systems modeled as Neutral Delay Differential Equations (NDDEs). These systems include delays in both the state variables and their first time derivatives. The proposed approach consists in descriptor model transformation that constructs an equivalent set of Delay Differential Algebraic ...

Small Signal Modeling and Stability Analysis of Modular Multilevel Converter Based on Harmonic State-Space Model

Energies, 2020
The stability of Modular multilevel converter (MMC) itself is the premise of analyzing the stability of MMC cascading with other cells, so this paper addressed the small-signal stability of MMC with dc voltage control mode which is the common operation ...
