Partially Segmented Permanent-Magnet Losses in Interior Permanent-Magnet Motors

Energies
Permanent-magnet losses in interior permanent-magnet (IPM) motors can result in high magnet temperatures and potential demagnetization. This study investigates using partially segmented magnets as an alternative to traditional segmented magnets to reduce

Smartphone‐Guided Visible Light Modulation of RSNOs for Antimicrobial Activity via Controlled Nitric Oxide Release

Advanced Science, EarlyView.
A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...

Iron loss calculation model of high‐voltage multi‐pole asynchronous motors considering high harmonic flux density

IET Electric Power Applications
A variable coefficient segmented iron loss calculation model is proposed for high‐voltage multi‐pole asynchronous motors, which fully considers the influence of high‐order harmonic magnetic density on such motors.

Farm labor scarcity and its uneven impacts on crop producers in the United States

American Journal of Agricultural Economics, EarlyView.
Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

An Analytical Thermal Model for Coaxial Magnetic Gears Considering Eddy Current Losses

Modelling
This work presents an analytical 2D model for estimating eddy current losses in the permanent magnets (PMs) of a coaxial magnetic gear (CMG), with a focus on loss minimization through magnet segmentation.

First Report of Uniparental Isodisomy of Chromosome 15 Revealing Angelman Syndrome and Microphthalmia Associated With a Novel Homozygous ALDH1A3 Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Paternal isodisomy of chromosome 15 (iUPD15) is a recognized cause of Angelman syndrome (AS), accounting for approximately 2%–5% of cases. Additionally, another recognized consequence of iUPD is the unmasking of autosomal recessive disorders. However, reports of recessive disorders resulting from iUPD15 remain scarce in the literature.

Ultra-high reduction of eddy current losses in additively manufactured soft magnetic material via a novel dense-stack lamination architecture

Materials & Design
Eddy current losses in motors and transformers are undesirable because they degrade energy efficiency. Several methods have been proposed to reduce it in additively manufactured (AM) soft magnetic materials but suffer from low design efficiency and ...

Eddy current losses in transformer windings

, 2020
Målet med denne masteroppgaven er å undersøke en semi-analytisk tapberegningsmetode, spesielt når man tar hensyn til virvelstrømstap i transformatorviklinger. Dette gjøres gjennom sammenligninger mellom simulerte og målte resultater, og gjennom sammenligninger av målte og nominell data fra produsenten.

North American Delphi Consensus Study on Sinonasal Malignancy Survivorship Care

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Survival for patients with sinonasal cancers has improved over the past decades, but there are no dedicated survivorship guidelines for this cohort. Objective To understand experts’ priorities and perspectives on key survivorship tenets (surveillance, second tumor screening, toxicity, and symptom management).
