Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics
Advanced Science, Volume 13, Issue 25, 4 May 2026.Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

4D spherically symmetric time-dependent quantum gravity amplitudes
European Physical Journal C: Particles and FieldsIn these short notes, we compute non-perturbatively the time-dependent quantum gravity amplitudes for a four-dimensional spherically symmetric space-time with space-like and time-like boundaries.

Holographic signatures of resolved cosmological singularities
Journal of High Energy Physics, 2019 The classical gravity approximation is often employed in AdS/CFT to study the dual field theory, as it allows for many computations. A drawback is however the generic presence of singularities in classical gravity, which limits the applicability of AdS ...

Discriminating quantum gravity models by gravitational decoherence
Nuclear Physics B, 2023 Several phenomenological approaches to quantum gravity predict the existence of a minimal measurable length and/or a maximum measurable momentum near the Planck scale.

Into the Black Box: Explicating Black Boxes and Its Effect on Mechanistic Reasoning
Journal of Research in Science Teaching, Volume 63, Issue 4-5, Page 412-432, May 2026.ABSTRACT Mechanistic reasoning is a powerful and vital approach for science students to explain scientific phenomena. Current research on students' mechanistic reasoning aims to enhance unpacking, that is, the identification and description of entities at lower scalar levels.

GraphNeuralCloth: A Graph‐Neural‐Network‐Based Framework for Non‐Skinning Cloth Simulation
Advanced Intelligent Systems, Volume 8, Issue 4, April 2026.This study presents a cloth motion capture system and a point‐cloud‐to‐mesh processing method to support the prediction of real‐world fabric deformation. GraphNeuralCloth, a graph neural‐network (GNN)‐based framework is also proposed to estimate the cloth morphology change in real time.

Quantum matter in quantum space-time
, 2013 Quantum matter in quantum space-time is discussed using general properties of energy-conservation laws. As a rather radical conclusion, it is found that standard methods of differential geometry and quantum field theory on curved space-time are ...

Semi‐autonomous Navigation of Magnetic Microcarriers for Knee Cartilage Regeneration
Advanced Intelligent Systems, Volume 8, Issue 4, April 2026.Autonomous navigation of magnetic microcarriers in complex 3D environments is investigated through a semi‐autonomous strategy integrating magnetic actuation with monocular visual feedback. Real‐time global tracking is achieved via radio‐frequency‐based localization and depth estimation, while model‐based computation determines optimal steering forces ...

Canonical gravity in two time and two space dimensions
, 2011 We describe a program for developing a canonical gravity in 2+2 dimensions (two time and two space dimensions). Our procedure is similar to the usual canonical gravity but with two times rather than just one time.
