Privacy-preserving schemes for Ad Hoc Social Networks: A survey
Mohamed Amine Ferrag, Leandros Maglaras, Ahmed Ahmim
In this paper, we review the state of the art of privacy-preserving schemes for ad hoc social networks, including, mobile social networks (MSNs) and vehicular social networks (VSNs…
The multitrace matrix model: An alternative to Connes NCG and IKKT model
Badis Ydri
We present a new multitrace matrix model, which is a generalization of the real quartic one matrix model, exhibiting dynamical emergence of a fuzzy two-sphere and its non-commutati…
Emergent fuzzy geometry and fuzzy physics in dimensions
Badis Ydri, Rouag Ahlam, Ramda Khaled
A detailed Monte Carlo calculation of the phase diagram of bosonic IKKT Yang-Mills matrix models in three and six dimensions with quartic mass deformations is given. Background eme…
Geometry in transition in four dimensions: A model of emergent geometry in the early universe and dark energy
Badis Ydri, Ramda Khaled, Rouag Ahlam
We study a six matrix model with global symmetry containing at most quartic powers of the matrices. This theory exhibits a phase transition from a geometrical p…
Probing the astrophysical origin of high-energy cosmic-ray electrons with Monte Carlo simulation
Reda Attallah
High-energy cosmic-ray electrons reveal some remarkable spectral features, the most noteworthy of which is the rise in the positron fraction above 10~GeV. Due to strong energy loss…
Linear and nonlinear fractional Voigt models
Amar Chidouh, Assia Guezane-Lakoud, Rachid Bebbouchi +2
We consider fractional generalizations of the ordinary differential equation that governs the creep phenomenon. Precisely, two Caputo fractional Voigt models are considered: a rheo…
