A FEM-Based Comparative Study of the Effect of Rotor Bar Designs on the Performance of Squirrel Cage Induction Motors

open access: yesEnergies, 2023
Induction motors (IM) are the most frequently used type of motor in the industry. The number of rotor slots, bar geometry, and conductivity of bar material have a strong impact on the torque profile and efficiency characteristics of induction motors ...

Image-Based Classification of Double-Barred Beach States Using a Convolutional Neural Network and Transfer Learning

open access: yesRemote Sensing, 2022
Nearshore sandbars characterize many sandy coasts, and unravelling their dynamics is crucial to understanding nearshore sediment pathways. Sandbar morphologies exhibit complex patterns that can be classified into distinct states.

On Extra Top Yukawa Couplings of a Second Higgs Doublet

open access: yesUniverse, 2022
A very likely New Physics in plain sight, but that the community does not see, is a second Higgs doublet that has a second set of Yukawa couplings. The extra tt and tc couplings can each drive baryogenesis, with O(1) Higgs quartic couplings providing a ...

Towards understanding the dynamics of the bar/bulge region in our Galaxy

open access: yesEPJ Web of Conferences, 2012
I review some of the work on bars which is closely linked to the bar/bulge system in our Galaxy. Several independent studies, using totally independent methods, come to the same results about the 3D structure of a bar, i.e., that a bar is composed of a ...

Changes in Triterpenes in Alismatis rhizoma after Processing Based on Targeted Metabolomics Using UHPLC-QTOF-MS/MS

open access: yesMolecules, 2021
Alismatis rhizoma (AR) has been used as an herbal medicine in China for over a thousand years. Crude AR, salt-processed AR (SAR), and bran-processed AR (BAR) are recorded in the Pharmacopoeia of the People′s Republic of China. However, the differences of

Modified bar bending method of thoracoscopic nuss procedure on pectus excavatum: a retrospective single-center study

open access: yesBMC Pediatrics, 2023
Background Pectus excavatum (PE) is the most common disease of chest wall deformity, with an incidence of 1 in 300—400 births. Nuss procedure has proved to be the best surgical treatment method and has been widely used after clinical use for 30 years. We

Comparison of the Standard vs. Thoracoscopic Extrapleural Modification of the Nuss Procedure—Two Centers’ Experiences

open access: yesChildren, 2022
Pectus excavatum is the most common congenital anterior chest wall deformity, with an incidence of 1:400 to 1:1000. Surgical strategy has evolved with the revolutionary idea of Donald Nuss, who was a pioneer in the operative correction of this deformity ...

MHC class I loci of the Bar-Headed goose (Anser indicus)

open access: yesGenetics and Molecular Biology, 2010
MHC class I proteins mediate functions in anti-pathogen defense. MHC diversity has already been investigated by many studies in model avian species, but here we chose the bar-headed goose, a worldwide migrant bird, as a non-model avian species. Sequences
