Continuous-time quantum walk spatial search on the Bollobás scale-free network
Tomo Osada, Bruno Coutinho, Yasser Omar +3
The scale-free property emerges in various real-world networks and is an essential property which characterizes the dynamics or features of such networks. In this work we investiga…
Nonlocal effects in plasmonic metasurfaces with almost touching surfaces
Fan Yang, Emanuele Galiffi, Paloma Arroyo Huidobro +1
Geometrical singularities in plasmonic metasurfaces have recently been proposed for the enhancement of light-matter interactions, owing to their broadband light-harvesting properti…
Nonlocal effects and enhanced nonreciprocity in current-driven graphene systems
Tiago A. Morgado, Mário G. Silveirinha
A graphene sheet biased with a drift electric current offers a tantalizing opportunity to attain unidirectional, backscattering-immune, and subwavelength light propagation, as prop…
Point Cloud Rendering after Coding: Impacts on Subjective and Objective Quality
Alireza Javaheri, Catarina Brites, Fernando Pereira +1
Recently, point clouds have shown to be a promising way to represent 3D visual data for a wide range of immersive applications, from augmented reality to autonomous cars. Emerging…
Formation of SMBH seeds in Pop III star clusters through collisions : the importance of mass loss
P. J. Alister Seguel, D. R. G. Schleicher, T. C. N. Boekholt +2
Runaway collisions in dense clusters may lead to the formation of supermassive black hole (SMBH) seeds, and this process can be further enhanced by accretion, as recent models of S…
Deep Representations for Cross-spectral Ocular Biometrics
Luiz A. Zanlorensi, Diego R. Lucio, Alceu S. Britto +2
One of the major challenges in ocular biometrics is the cross-spectral scenario, i.e., how to match images acquired in different wavelengths (typically visible (VIS) against near-i…
