Dispersion management in highly nonlinear, carbon disulfide filled holey fibers [PDF]

, 2008
We study various fiber designs which incorporate a highly nonlinear liquid, carbon disulfide, with the aim of designing a structure with the highest possible nonlinearity and at the same time a low and flattened dispersion at telecom wavelengths, as ...

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Impact of hemodialysis on P-wave amplitude, duration, and dispersion

Indian Pacing and Electrophysiology Journal, 2007
Atrial fibrillation (AF) is a frequent arrhythmia in patients undergoing hemodialysis (HD). P wave duration (PWdu) and P wave dispersion (PWdi) have been shown to be predictors of emerging AF in different clinical conditions.

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

A solid one-dimensional microstructured optical fiber with high nonlinearity and low dispersion at 1.55 microns

, 2009
We report on the fabrication of a solid one-dimensional microstructured fiber with high nonlinearity and low dispersion at 1.55µm. A four-wave-mixing based tunable wavelength-conversion scheme was experimentally demonstrated in just 1.5m of this ...

Increased P wave dispersion in patients with liver steatosis

Medicinski Glasnik, 2010
Aim Hepatic steatosis is associated with metabolic and hemodynamicabnormalities induced by insulin resistance and inflammatory state. Since abnormalities of P wave dispersion may be accompanied with latter issues we evaluated this subject in patients ...

Comparison of P-wave dispersion in healthy dogs, dogs with chronic valvular disease and dogs with disturbances of supraventricular conduction

Acta Veterinaria Scandinavica, 2011
Background P-wave dispersion (Pd) is a new ECG index used in human cardiology and veterinary medicine. It is defined as the difference between the maximum and the minimum P-wave duration recorded from multiple different ECG leads.
