A New Theory for Locating Line Fault in Power System: Simulation Part

open access: yesIEEE Access, 2019
Three time-reversal-based fault location methods are derived from the theoretical part of this paper, which is named currents-in-time-domain method, forward-currents-in-frequency-domain method, and forward-currents-in-frequency-domain-with-compensation ...

Fault location in cellular arrays [PDF]

open access: yesProceedings of the November 18-20, 1969, fall joint computer conference on - AFIPS '69 (Fall), 1969
Testing of complex integrated cellular logic circuits fabricated using LSI techniques has become a source of concern to users and manufacturers. Since an economically feasible solution to testing problems is not visible for the complex arrays contemplated for the near future, manufacturers have acknowledged the seriousness of the problem.

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Novel system model‐based fault location approach using dynamic search technique

open access: yesIET Generation, Transmission & Distribution, 2021
Impedance‐based fault location (IBFL) approaches are the most commonly used fault location methods in digital relays. However, each IBFL approach is designed specific to a line or network configuration and thus is not universal. For example, complex line

Sociodemographic Factors Associated With Later Stage at Diagnosis of Pediatric Germ Cell Tumors: A Report From Children's Oncology Group Registries ACCRN07 and APEC14B1

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Germ cell tumors (GCTs) often arise in the ovaries and testes (extracranial) but can also develop in the brain (intracranial). We examined the relationship of individual, family, and community‐level socioeconomic status (SES) with stage of disease at diagnosis in a cohort of pediatric patients with GCT from Children's Oncology Group

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

open access: yesPediatric 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).
