A Pincherle‐Type Convergence Theorem for Generalized Continued Fractions in Banach Algebras

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This contribution is dedicated to the interdependence of higher order linear difference equations and generalized continued fractions in Banach algebras. It turns out that the computation of certain subdominant solutions of a higher order linear difference equation can be done more efficiently by considering its adjoint equation.

Revealing Competing Kinetic Pathways in Amphiphilic Pt(II) Complex Self‐Assembly via Deep Learning with Graph Neural Networks

open access: yesAggregate, Volume 6, Issue 12, December 2025.
GraphVAMPnet, a graph neural network–based deep learning framework, successfully overcomes the permutation challenge in analyzing molecular dynamics trajectories of self‐assembly of PtB complexes. It accurately identifies three slow collective variables and reveals two competing kinetic pathways—incremental and hopping growth—governing Pt(II ...

Quantum‐Noise‐Driven Generative Diffusion Models

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 12, December 2025.
Diffusion Models (DMs) are today a very popular class of generative models for Machine Learning (ML), using a noisy dynamics to learn an unknown density probability of a finite set of samples in order to generate new synthetic data. This study proposes a method to generalize them into the quantum domain by introducing and investigating what are termed ...

Virtual Sensing of Wind Turbine Loads With Multi‐Hidden Markov Models for Above‐Rated Wind Speeds

open access: yesWind Energy, Volume 28, Issue 12, December 2025.
ABSTRACT The growing demand for wind energy necessitates efficient health monitoring strategies to ensure the long‐term reliability of wind turbines. Monitoring critical loads, such as flapwise blade root moments and tower base fore‐aft moments, is crucial for preventing turbine fatigue and failure. However, direct measurements through physical sensors

A Survey on Reinforcement Learning for Optimal Decision‐Making and Control of Intelligent Vehicles

open access: yesCAAI Transactions on Intelligence Technology, Volume 10, Issue 6, Page 1593-1615, December 2025.
ABSTRACT Reinforcement learning (RL) has been widely studied as an efficient class of machine learning methods for adaptive optimal control under uncertainties. In recent years, the applications of RL in optimised decision‐making and motion control of intelligent vehicles have received increasing attention.

Efficient and physically consistent generation of 2D concrete mesostructures via a regressor‐guided diffusion framework

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 31, Page 6622-6637, 29 December 2025.
Abstract Concrete mesostructure modeling is critical for simulation‐driven material design, as it directly influences the accuracy of mechanical and durability analyses. However, conventional methods such as computed tomography–based reconstruction and aggregate sequential placement suffer from low efficiency and limited controllability.
