Generalized Portrait Quality Assessment
Nicolas Chahine, Sira Ferradans, Javier Vazquez-Corral +1
Automated and robust portrait quality assessment (PQA) is of paramount importance in high-impact applications such as smartphone photography. This paper presents FHIQA, a learning-…
Fluctuations, correlations, and Casimir-like forces in the homogeneous cooling state of a granular gas
Jesús David Jiménez Oliva, Pablo Rodriguez-Lopez, Nagi Khalil
The fluctuating hydrodynamics by Brey et. al. is analytically solved to get the long-time limit of the fluctuations of the number density, velocity field, and energy density around…
Cooperation transitions in social games induced by aspiration-driven players
Miguel Aguilar-Janita, Nagi Khalil, Inmaculada Leyva +1
Cooperation and defection are social traits whose evolutionary origin is still unresolved. Recent behavioral experiments with humans suggested that strategy changes are driven main…
Deterministic and stochastic cooperation transitions in evolutionary games on networks
Nagi Khalil, I. Leyva, J. A. Almendral +1
Although the cooperative dynamics emerging from a network of interacting players has been exhaustively investigated, it is not yet fully understood when and how network reciprocity…
Structured interactions as a stabilizing mechanism for competitive ecosystems
Violeta Calleja-Solanas, Nagi Khalil, Jesús Gómez-Gardeñes +2
How large ecosystems can create and maintain the remarkable biodiversity we see in nature is probably one of the biggest open questions in science, attracting attention from differ…
Approach to consensus in models of continuous-opinion dynamics: a study inspired by the physics of granular gases
Nagi Khalil
A model for continuous-opinion dynamics is proposed and studied by taking advantage of its similarities with a mono-dimensional granular gas. Agents interact as in the Deffuant mod…
