Linear higher-order Maxwell-Einstein-Scalar theories
In the context of the Higher-Order Maxwell-Einstein-Scalar (HOMES) theories, which are invariant under spacetime diffeomorphisms and U(1) gauge symmetry, we study two broad subclasses: the first is up to linear in R μναβ , ∇ μ ∇ ν ϕ, ∇ ρ F μν and up to ...

Predicting Performance of Hall Effect Ion Source Using Machine Learning
This study introduces HallNN, a machine learning tool for predicting Hall effect ion source performance using a neural network ensemble trained on data generated from numerical simulations. HallNN provides faster and more accurate predictions than numerical methods and traditional scaling laws, making it valuable for designing and optimizing Hall ...

A scalable distributed observer framework for LiDAR sensor networks is presented for robust tracking and pose estimation of mobile robots. By combining adaptable 3D detection, clustering‐based communication reduction, and intermittent inertial fusion, accurate and efficient estimation is achieved under occlusions and sensing constraints, with formally ...

A novel proton decay signature at DUNE, JUNO, and Hyper-K
Proton decay, although unobserved so far, is a natural expectation when attempting to explain the baryon asymmetry of the universe. p → K + ν ¯ $$ p\to {K}^{+}\overline{\nu} $$ or p → K + χ ~ 1 0 $$ p\to {K}^{+}{\overset{\sim }{\chi}}_1^0 $$ , with χ ~ 1
