Quantum GraviElectro Dynamics

Annalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Optimal Transport Autoregression to Forecast High‐Frequency Financial Data Distributions

Applied Stochastic Models in Business and Industry, Volume 42, Issue 1, January/February 2026.
ABSTRACT In this paper, we study the properties and performance of optimal transport autoregression in modeling and forecasting high‐frequency financial data distributions. We build on a class of univariate autoregressive transport models recently proposed in the literature (Zhu and Müller) where the distributional time series dynamics is modeled ...

Using Hierarchical Bayesian Analysis to Identify At‐Risk Students in Engineering Mathematics Prerequisites

Computer Applications in Engineering Education, Volume 34, Issue 1, January 2026.
ABSTRACT Engineering educators need practical methods to identify which students are struggling and which course topics require additional instructional support. This study applies hierarchical Bayesian analysis to student performance data from the ASSISTments 2009 dataset containing 446,844 responses from 4151 students across 110 mathematical skills ...

Stability Analysis of Different Quaternion‐Valued Impulsive BAM Neural Networks With Unknown Parameters and Time‐Varying Delays

Engineering Reports, Volume 8, Issue 1, January 2026.
This work tackles the unresolved stability problem of heterogeneous quaternion‐valued BAM neural networks plagued by unknown parameters, time‐varying delays, and impulses. By synergizing Lyapunov theory with inequality techniques, we establish rigorous, yet practical, global stability conditions.
