Radiofrequency catheter ablation of idiopathic ventricular ectopy

open access: yesZdravniški Vestnik, 2013
Idiopathic ventricular ectopy with left bundle branch block morphology and inferior axis commonly originates from the right ventricular outflow tract. It is very unusual for this ectopy to originate from the pulmonary artery trunk.

Accuracy Enhancement of Automated System for Multicomponent Batching of Bulk Materials

open access: yesMATEC Web of Conferences, 2015
In the paper the choice of reasonable structure of automated system for multicomponent batching of bulk materials has been substantiated to minimize the batching error of about 3% in case the recipe mixture includes small components of big importance in ...

Resolving Nanoscale Heterogeneities in Lead Halide Perovskites Through Low‐Dose Concurrent 4D‐STEM‐EDX Mapping

open access: yesAdvanced Materials, EarlyView.
Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies

Time-frequency Analysis of Multicomponent LFM signal based on Hough and Chirplet Transform

open access: yesMATEC Web of Conferences, 2018
The Chirplet Transform (CT) is effective in the characterization of IF for mono-component linear-frequency-modulated signal. However, During the initialization process, using the peak of the time-frequency map of the short-time Fourier transform to fit ...
