Electrodiagnostic profile of conduction slowing in amyotrophic lateral sclerosis

Heliyon, 2023
Objective: Since motor nerve conduction slowing can occur due to loss of large axons, we investigate the conduction slowing profile in amyotrophic lateral sclerosis (ALS) and identify the limits beyond which the diagnosis of exclusive axonal loss is ...

Gentamicin‐induced sensorineural auditory loss in healthy adult horses

Journal of Veterinary Internal Medicine, 2021
Background Irreversible sensorineural auditory loss has been reported in humans treated with aminoglycosides but not in horses. Objective Investigate if auditory loss occurs in horses treated using the recommended IV daily dosage of gentamicin for 7 ...

Valence band excitations in V_2O_5 [PDF]

, 1999
We present a joint theoretical and experimental investigation of the electronic and optical properties of vanadium pentoxide. Electron energy-loss spectroscopy in transmission was employed to measure the momentum-dependent loss function. This in turn was

A Model of Heat Conduction

, 2008
We define a deterministic ``scattering'' model for heat conduction which is continuous in space, and which has a Boltzmann type flavor, obtained by a closure based on memory loss between collisions.

Influence of Conduction Angles on Single Layer Switched Reluctance Machines [PDF]

, 2016
This paper investigates the influence of conduction angles on the performances of two 3-phase 12-slot/8-pole short pitched switched reluctance machines (SRMs): single layer SRM with conventional winding (SL-CSRM), and single layer SRM with mutually ...

Investigation on filter requirements and stability effects of SiC MOSFET-based high-frequency grid-connected converters

The Journal of Engineering, 2019
The new era of power semiconductor devices is exploiting the high potential of wide bandgap device-based high-frequency power converters. The advanced capabilities of Silicon carbide (SiC) semiconductors allow the power converters to switch at higher ...

Electron Energy-Loss Spectroscopy: A versatile tool for the investigations of plasmonic excitations

, 2014
The inelastic scattering of electrons is one route to study the vibrational and electronic properties of materials. Such experiments, also called electron energy-loss spectroscopy, are particularly useful for the investigation of the collective ...

Plasmons on the edge of MoS2 nanostructures [PDF]

, 2014
Using ab initio calculations we predict the existence of one-dimensional (1D), atomically confined plasmons at the edges of a zigzag MoS2 nanoribbon. The strongest plasmon originates from a metallic edge state localized on the sulfur dimers decorating ...

Power loss investigation in HVDC for cascaded H-bridge multilevel inverters (CHB-MLI) [PDF]

, 2015
In the last decade, the use of voltage-source multilevel inverters in industrial and utility power applications has been increased significantly mainly due to the many advantages of multilevel inverters, compared to conventional two level inverters ...

Boosting electromagnetic wave absorption of Ti₃AlC₂ by improving effective electrical conductivity

Journal of Advanced Ceramics, 2023
Electromagnetic wave-absorbing (EMA) materials at high temperatures are limited by poor conduction loss (Lc). However, adding conductors simultaneously increases the conduction loss and interfacial polarization loss, leading to a conflict between ...
