Adaptive blind image deblurring and denoising

Scandinavian Journal of Statistics, EarlyView.
Abstract Blind image deblurring aims to reconstruct the original image from its blurred version without knowing the blurring mechanism. This is a challenging ill‐posed problem because there are infinitely many possible solutions. The ill‐posedness is further exacerbated if the blurring mechanism depends on the pixel location.

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Analysis of Turbulent Modeling for Free‐Surface Flows Using a Hybrid RANS‐LES Model and Particle‐Based Moving Particle Semi‐Implicit Method

International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.
A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

Non‐Negligible Influence of Forcing Mechanisms on Turbulent Mixing at Low Reynolds Numbers: A One‐Dimensional Turbulence Study

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT This study presents a numerical investigation of passive scalar mixing in homogeneous isotropic turbulence (HIT). Different volumetric forcing schemes have been used in the literature, but the side effects are rarely discussed, either because these are assumed irrelevant or because it is too costly to conduct such an analysis with a high ...
