DL_FFLUX Refactored: Accelerating Quantum Chemical Topology Simulations With Optimized Parallelization [PDF]

Journal of Computational Chemistry, Volume 47, Issue 24, September 15, 2026.
DL_FFLUX, which houses the quantum‐topological machine‐learning potential FFLUX, is refactored and computationally optimized through software‐level code optimization and prediction caching. The new implementation accelerates molecular dynamics simulations 93‐fold for the largest models while preserving accuracy.

On optimisation of Paganin's method for propagation‐based X‐ray phase‐contrast imaging and tomography [PDF]

Journal of Microscopy, Volume 303, Issue 1, Page 37-52, July 2026.
Abstract Paganin's method for image reconstruction in propagation‐based phase‐contrast X‐ray imaging and tomography has enjoyed broad acceptance in recent years, with over one thousand publications citing its use. The present paper discusses approaches to optimisation of the method with respect to simple image quality metrics, such as signal‐to‐noise ...

ZEN-IQA: Zero-Shot Explainable and No-Reference Image Quality Assessment With Vision Language Model

IEEE Access
No-reference image quality assessment (NR-IQA), which aims to estimate the perceptual quality of a degraded image without accessing the corresponding original image, is a key challenge in low-level computer vision.
