— The general purpose of spin-electronics is to take advantage of the spin of the electrons in addition to their electrical charge to conceive innovative electronic components. These components combine magnetic materials which are used as spin-polarizer or analyzer together with semiconductors or insulators. SPINTEC Laboratory works on the development of(More)
Bilateral posterior fracture-dislocation of the shoulder is a very rare injury. Almost 50% of bilateral posterior dislocations are due to a convulsive seizure, rising to 90% if the dislocations are associated with fractures. Electric shock accounts for less than 5% of bilateral posterior dislocations of the shoulder. A systematization of the clinical and(More)
Vibrato is a frequency modulation effect of the singing voice and is very relevant in musical terms. Its most important characteristics are the vibrato frequency (in Hertz) and the vibrato extension (in semitones). In singing teaching and learning, it is very convenient to provide a visual feedback of those two objective signal characteristics, in(More)

Transfer Learning (TL) has gained significant interest in the Machine Learning (ML) community. Aiming to overcome standard ML learning models assumption that data distributions are the same independently of its origins, a wide variety of works have emerged to tackle this issue. Nowadays, with data available on large amounts and from different applications ,(More)
