Beyond Parameter Space: NTK-Guided Personalized Aggregation for Robust Federated Learning
Mirko Konstantin, Stefan Zachow, Anirban Mukhopadhyay
Federated learning (FL) enables collaborative model training across distributed clients while keeping data local. A central challenge is determining which client updates are benefi…
Spectral Admissibility of Real Observers in Euclidean de Sitter Gravity
Ricardo EspÃndola, Ahmed Farag Ali
The Euclidean de Sitter path integral contains the familiar phase associated with conformal negative modes. Maldacena's construction shows that a suitably included real observer ca…
Mass Without Mass from a Berry--Shifted SU(3) Holonomy Rotor
Ahmed Farag Ali
We identify a local, gauge-invariant mechanism that generates a finite spectral scale in pure SU(3) Yang--Mills theory on a punctured three-ball. Fixing a center sec…
Relational de Sitter State Counting with an SU(3) Clock
Ahmed Farag Ali
Motivated by Maldacena's observer-centric formulation of de~Sitter physics \cite{Maldacena:2024spf}, we develop an observer-dependent state-counting framework in Euclidean de~Sitte…
Quantum Spacetime Imprints: The 24-Cell, Standard Model Symmetry and Its Flavor Mixing
Ahmed Farag Ali
In our previous work \cite{FaragAli:2024jpo} we outlined an exploratory framework in which the 24-cell acts both as the quantum of spacetime and as a geometric representation of el…
GUP/BEB correspondence
Ahmed Farag Ali
We develop a fully expectation--value formulation of the GUP/Bekenstein--bound (BEB) correspondence, building on \cite{Ali:2024tbd,Ali:2022ckm,Ali:2022ulp}. Using Dirac's commutato…
