Multi-objective GPR-based design optimization of high frequency transformers

open access: yesPower Electronic Devices and Components
FEA-based design optimization of high frequency transformers (HTSs) are by far more accurate but they come at huge computational cost. This paper presents a Gaussian Process Regression-based multiobjective design optimization technique for HFTs.

Field-Balanced Windings for High-Frequency Transformers

open access: yesIEEE Open Journal of Power Electronics
High-frequency operation is a well-established strategy for miniaturizing power converters, but eddy-current losses in magnetics thermally limit its effectiveness in high-power converters. Interleaved windings, which reduce the magnetic fields around the

Improving Vision Transformers by Revisiting High-Frequency Components

open access: yes, 2022
The transformer models have shown promising effectiveness in dealing with various vision tasks. However, compared with training Convolutional Neural Network (CNN) models, training Vision Transformer (ViT) models is more difficult and relies on the large-scale training set.

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

High frequency transformer computer modeling [PDF]

open access: yes2007 Australasian Universities Power Engineering Conference, 2007
Frequency response analysis (FRA) technique is nowadays widely used in both factory and field applications as a diagnostic tool for power transformers. The main problem about FRA techniques is to interpret the observed evolution of the frequency response in order to identify failures.

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).

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

open access: yesPediatric 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 ...
