Mist and Edge Computing Cyber-Physical Human-Centered Systems for Industry 5.0: A Cost-Effective IoT Thermal Imaging Safety System
P. Fraga-Lamas, D. Barros, S. I. Lopes +1
While many companies worldwide are still striving to adjust to Industry 4.0 principles, the transition to Industry 5.0 is already underway. Under such a paradigm, Cyber-Physical Hu…
Tight Bell inequalities from polytope slices
José Jesus, Emmanuel Zambrini Cruzeiro
We derive new tight bipartite Bell inequalities for various scenarios. A bipartite Bell scenario is defined by the numbers of settings and outcomes per party, , …
Equivalence Principle in Classical and Quantum Gravity
Nikola Paunkovic, Marko Vojinovic
We give a general overview of various flavors of the equivalence principle in classical and quantum physics, with special emphasis on the so-called weak equivalence principle, and…
Noncontact frictional force between surfaces by peristaltic permittivity modulation
Daigo Oue, Kun Ding, J. B. Pendry
In this study, we reveal noncontact frictional forces between surfaces in the presence of peristaltic permittivity modulation. Our setup comprises a conducting medium, an air gap,…
Qubit Picture of Virtual Particles
Gonçalo M. Quinta
We show that virtual particles, despite being unobservable, can be described by quantum operators which can be interpreted under certain conditions as valid qubit quantum states. F…
Directional dependence of the plasmonic gain and nonreciprocity in drift-current biased graphene
Tiago A. Morgado, Mário G. Silveirinha
Here, we investigate the nonreciprocal propagation and amplification of surface plasmons in drift-current biased graphene, using both Galilean and relativistic-type Doppler shift t…
