Vision Research, 2015 It is well known that visible luminance gradients may generate contrast effects. In this work we present a new paradoxical illusion in which the luminance range of gradual transitions has been reduced to make them invisible. By adopting the phenomenological method proposed by Kanizsa, we have found that unnoticeable luminance gradients still generate ...

On phantom thermodynamics [PDF]
Physics Letters B, 2008 The thermodynamic properties of dark energy fluids described by an equation of state parameter $ =p/ $ are rediscussed in the context of FRW type geometries. Contrarily to previous claims, it is argued here that the phantom regime $ 0$ and $S>0$ in the course of the Universe expansion.

Biometric Identity Based on Intra-Body Communication Channel Characteristics and Machine Learning
Sensors, 2020 In this paper, we propose and validate using the Intra-body communications channel as a biometric identity. Combining experimental measurements collected from five subjects and two multi-layer tissue mimicking materials’ phantoms, different machine
