On the Method of Harmonic Balance for Lumped‐Element Transformer Models

International Journal of Circuit Theory and Applications, EarlyView.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

The Relationship Between Precuneus Thickness and Psychopathology in Adolescent Females With Anorexia Nervosa

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is a severe psychiatric disorder with structural brain alterations; however, the roles of cortical surface area (CSA) and cortical thickness (CTh) during adolescence remain unclear. Building on frequent reports of gray matter reductions in the cingulate cortex and precuneus, this study assesses CSA, CTh, and ...

Pseudoaneurysms as a complication of stereoelectroencephalography: Case series and clinical recommendations

Epilepsia, EarlyView.
Abstract Objective Stereoelectroencephalography (sEEG) is commonly employed in the workup for epilepsy surgery in patients with focal drug‐resistant epilepsy (DRE). Intracranial hemorrhage is a known complication, with reported incidence rates ranging from .9% to 19.1%. Rarely, pseudoaneurysms have been reported in literature as a potential cause. This

Synchronous reluctance machines: performance evaluation with and without ferrite magnets

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Nowadays, a great interest in the efficiency and the cost of electrical machines has been noticed. Therefore, Synchronous Reluctance Motors (SynRMs) have become more attractive alternative for induction and permanent magnet (PM) synchronous machines in several industrial applications.

Virtual Magnetic Resonance Elastography Using a Deep Generative Model for Liver Fibrosis Staging

iRADIOLOGY, EarlyView.
The proposed Registration‐based Generative Adversarial Network‐Convolutional Block Attention Module (RegGAN‐CBAM) model efficiently and reliably generates virtual MR elastography using diffusion weighted imaging. Strong correlation between virtual and native MR elastography for liver stiffness and viscosity are observed.
