Feasibility of endovascular stentectomy using a snare over stent-retriever (SOS) technique was evaluated in a silicon flow model and an in vivo swine GLASS BABY BOTTLE model.In vitro, stentectomy of different intracranial stents using the SOS technique was feasible in 22 out of 24 (92%) retrieval maneuvers.In vivo, Manicure Set stentectomy was succ
A novel blind signal extraction (BSE) scheme for the removal of eye-blink artifact from electroencephalogram (EEG) signals is proposed.In this method, in order to remove the artifact, the source extraction algorithm is provided with an estimation of the column of the mixing matrix corresponding to the point source eye-blink artifact.The eye-blink s
In order to solve problems of low efficiency and poor accuracy of existing mine hoist fault diagnosis methods, a fault diagnosis method of mine hoist based on fuzzy fault tree and Bayesian network was proposed.Firstly, denoising preprocessing and multi-source information fusion are carried out for hoist running parameters collected by sensors in re
The illuminated manuscripts at the Gulbenkian Museum were produced in the 17th century, in scriptoria of the Armenian diaspora.In this work, we selected analytical methods that can be used in situ to Bumpers study the colors of the illuminations.Scientific analysis based on fiber-optics reflectance spectroscopy in the visible and Raman spectroscopy
The safety of bridge piers located in navigation waterways is often threatened by passing vessels nowadays.Empirical formulas such as those provided by AASHTO Guide Specification are currently extensively used to predict impact forces using equivalent static methods.However, the important dynamic effects involved in an impact event cannot be consid
