Comparative Analysis in Single-Phase Induction Motors: Analytical, Numerical, and Load Tests

IEEE Access
Single-phase induction machines have two windings in the stator to produce a rotating field: a main winding and an auxiliary winding. The stator slot leakage inductance varies with the position of the coils within the slot.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

Impact of Asymmetrical Leakage Inductance on a 380 V–12 V LLC Converter with Synchronous Rectifier for DC Transformer Application

Energies
High-density 380 V–12 V LLC resonant converters typically employ planar transformers with integrated leakage inductance. To achieve Zero-Voltage Switching (ZVS), an air gap is introduced to adjust the magnetizing inductance (Lm). However, this gap alters

CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

A Novel Method of Estimating Induction Motor q-axis Leakage Inductance

Kongzhi Yu Xinxi Jishu, 2010
The q-axis leakage inductance Ls is always used in the control of induction motor. The parameters generally come from the analysis and calculation of the magnetic field or magnetic path, so some errors are hard to avoid.

Dimethyl Fumarate, But Not Rituximab, Reduces Serum GFAP Levels and PIRMA in Relapsing–Remitting MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) levels are believed to reflect mainly acute and chronic disease processes in multiple sclerosis (MS), respectively. In this study, we investigated whether dimethyl fumarate (DMF) and rituximab (RTX) differentially affect these biomarkers.
