Inrush Current Reduction of Three-Phase Transformers Using Optimal Energization Angle Control

open access: yesIEEE Access
When a transformer is energized, the inrush current can reach several tens of times higher than the steady-state magnetizing current, which may cause maloperation of protective relays, voltage dips and deterioration of power quality.

Witnessing the magnetospheric boundary at work in Vela X-1

open access: yes, 2011
We present an analysis of the Vela X-1's "off-states" based on Suzaku observations taken in June 2008. Defined as states in which the flux sudden decreases below the instrumental sensitivity, these "off-states" have been interpreted by several authors as

The swan song: the disappearance of the nucleus of NGC 4051 and the echo of its past glory [PDF]

open access: yes, 1998
BeppoSAX observed the low-luminous Seyfert 1 Galaxy NGC4051 in a ultra-dim X-ray state. The 2-10 keV flux (1.26 x 10^{-12} erg/cm^2/s) was about 20 times fainter than its historical average value, and remained steady along the whole observation (~2.3 ...

A New Method to Evaluate Residual Flux Thanks to Leakage Flux, Application to a Transformer [PDF]

open access: yesIEEE Transactions on Magnetics, 2014
This paper presents a new method to estimate the residual flux in the magnetic circuit of a transformer, which is the key data to determine the ideal closing time for the re-energization of a transformer. The methodology described is based on the measurement with fluxgate sensors of the magnetic field induced by the leakage flux around a single-phase ...

Patient Activation in Childhood, Adolescent, and Young Adult Cancer Survivors: Current Insights and Implications for Survivorship Care—A Systematic Review From the e‐QuoL Project

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Patient activation—encompassing knowledge, confidence, and skills in managing individual's health—is a cornerstone of person‐centered care. However, its significance among childhood, adolescent, and young adult cancer survivors (CAYACS) remains unexplored. This article examines the application of the 13‐item Patient Activation Measure (

Mantle geoneutrinos in KamLAND and Borexino

open access: yes, 2012
The KamLAND and Borexino experiments have observed, each at ~4 sigma level, signals of electron antineutrinos produced in the decay chains of thorium and uranium in the Earth's crust and mantle (Th and U geoneutrinos).

Imaging of High‐Risk Neuroblastoma: Recommendations From SIOPEN Radiology and Nuclear Medicine Specialty Committees

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...

Dust Distribution in Gas Disks. A Model for the Ring Around HR 4796A [PDF]

open access: yes, 2000
There have been several model analyses of the near and mid IR flux from the circumstellar ring around HR4796A. In the vicinity of a young star, the possibility that the dust ring is embedded within a residual protostellar gas disk cannot be ruled out. In

Inferring interplanetary flux rope orientation with the minimum residue method [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2009
There are many 2‐D models that can be used to describe the structure of the interplanetary flux rope (IFR), such as the force‐free model, the nonforce‐free model, and the inertial model. For each model, one or multiple field line invariants exist. In this study, we introduce a new definition of the quantity, residue, based on all field line invariants ...

Effects of Cancer Treatment on Somatosensory and Nociceptive Processing in Children and Adolescents: A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Chemotherapy‐induced peripheral neuropathy remains a major complication in pediatric cancer, with disrupted somatosensory and nociceptive processing being a key aspect. This review synthesizes empirical studies on alterations in somatosensory and nociceptive processing in children and adolescents with cancer.
