MAD‐HAR: Privacy‐Preserving On‐Device Human Action Recognition via Multiagent LLM Debate

IET Software, Volume 2026, Issue 1, 2026.
Human action recognition (HAR) is a fundamental component of ubiquitous computing, yet its wide‐range applications are hindered by privacy concerns. Specifically, high‐accuracy models typically require cloud‐based processing that compromises sensitive visual data, while privacy‐preserving on‐device models suffer from limited reasoning capacities and ...

Axiomatic formulations of modified gravity theories with nonlinear dispersion relations and Finsler–Lagrange–Hamilton geometry

European Physical Journal C: Particles and Fields, 2018
We develop an axiomatic geometric approach and provide an unconventional review of modified/nonlinear gravity theories, MGTs, with modified dispersion relations, MDRs, encoding Lorentz invariance violations, LIVs, classical and quantum random effects ...

FinalKAN: A Dual‐Stream KAN Network Integrating Multisource Features for Radio Telescope Pointing Correction

Advances in Astronomy, Volume 2026, Issue 1, 2026.
This paper investigates the degradation of pointing accuracy in the Kunming 40‐m radio telescope due to long‐term equipment aging and environmental disturbances. Conventional linear pointing models are constrained by their linear modeling framework, making it difficult to accurately represent the nonlinear errors induced by temperature, wind speed, and

Gravity quantized

, 2010
..."but we do not have quantum gravity." This phrase is often used when analysis of a physical problem enters the regime in which quantum gravity effects should be taken into account.

DePerio: Deep Learning‐Based Oral Inflammatory Load Quantification for Periodontal Applications

Advanced Intelligent Systems, Volume 7, Issue 12, December 2025.
a) Inflammation and oral polymorphonuclear neutrophil (oPMN) Migration: Dental plaque accumulation leads to inflammation, prompting white blood cells (WBCs), particularly oPMNs, to migrate from blood vessels through the gingival epithelium into the oral cavity.

Gravitational length stretching: Curvature-induced modulation of quantum probability densities

Open Physics
We introduce gravitational length stretching (GLS) as a novel quantum-gravitational phenomenon that distorts the spatial probability distribution of quantum particles in curved spacetime.

Geometry and Physics of Null Infinity

, 2015
In asymptotically Minkowski space-times, one finds a surprisingly rich interplay between geometry and physics in both the classical and quantum regimes. On the mathematical side it involves null geometry, infinite dimensional groups, symplectic geometry ...

Quantization of scalar perturbations in brane-world inflation

, 2004
We consider a quantization of scalar perturbations about a de Sitter brane in a 5-dimensional anti-de Sitter (AdS) bulk spacetime. We first derive the second order action for a master variable $\Omega$ for 5-dimensional gravitational perturbations. For a

Einstein-Gilbert-Straus solution of Einstein field equations: Timelike geodesic congruence with conventional and quantized fundamental metric tensor

Nuclear Physics B
In a cosmic background characterized by inhomogeneity, anisotropy, and spherical symmetry, a nonsingular solution to the Einstein field equations is established through the application of both conventional and quantized fundamental metric tensor.

Quantization of scalar fields in curved background, deformed Hopf algebra and entanglement [PDF]

, 2002
A suitable deformation of the Hopf algebra of the creation and annihilation operators for a complex scalar field, initially quantized in Minkowski space--time, induces the canonical quantization of the same field in a generic gravitational background ...
