(2021-12)Magnetic resonance images (MRIs) enable neuroradiologists to investigate the human brain to look for possible causes of disease. The clinical interpretation of these images is, however, mostly limited to subjective assessment or a rough measurement of ... -
(Reykjavik University, School of Science and Engineering, 2019-05-17)Maintaining small physical dimensions of antenna structures is an important consideration for contemporary wireless communication systems. Typically, antenna miniaturization is achieved through various topological modifications of the basic antenna ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Electrical and Computer Engineering, 2021-12-16)Hyperspectral images (HSIs) acquired by hyperspectral imaging sensors contain hundreds of spectral bands. The abundant spectral information provided by an HSI makes it possible to discriminate different materials in a scene. Therefore, HSIs have ...

Piezoresistance characterization of silicon nanowires in uniaxial and isostatic pressure variation (MDPI AG, 2022-08-23)Silicon nanowires (SiNWs) are known to exhibit a large piezoresistance (PZR) effect, making them suitable for various sensing applications. Here, we report the results of a PZR investigation on randomly distributed and interconnected vertical silicon ...

(MDPI AG, 2019-02-21)Fabrication and sensor application of a simple plasmonic structure is described in this paper. The sensor element consists of nano-patterned gold film brought about from two-dimensional periodic photoresist templates created by holographic laser ...

(Beilstein Institut, 2018-05-22)We consider core–shell nanowires with prismatic geometry contacted with two or more superconductors in the presence of a magnetic field applied parallel to the wire. In this geometry, the lowest energy states are localized on the outer edges of the ...

(Institute of Electrical and Electronics Engineers (IEEE), 2024)Molecular dynamics simulations, with full Coulomb interaction, are used to model short-pulse photoemission from a finite area in a microdiode. We demonstrate three emission regimes, source-limited emission, space-charge-limited emission for short pulses, ...

(Beilstein Institut, 2018-04-12)In this paper we consider charge current generated by maintaining a temperature difference over a nanowire at zero voltage bias. For topological insulator nanowires in a perpendicular magnetic field the current can change sign as the temperature of one ...
