Stochastic Galerkin and Monte Carlo Methods for Parabolic Problems: Numerical Performance of Variational Matrix‐Free Approximations

ABSTRACT Stochastic Galerkin methods offer unexplored potential for the numerical simulation of parabolic problems with random variables, in particular if they are combined with variational discretizations of the space and time variables. Due to the high dimensionality, the solut...

Subgroup variations in effectiveness of femoropopliteal sirolimus versus paclitaxel-coated balloon angioplasty: post hoc results of the randomised SIRONA trial

INTRODUCTION: The randomised SIRONA trial showed that sirolimus-coated balloon (SCB) angioplasty was non-inferior to paclitaxel-coated balloon angioplasty (PCB) regarding femoropopliteal primary patency. There was no difference in clinically driven target lesion revascularisation...

Mixed reality simulation of guided needle insertion: effects of interaction and visual fidelity

PURPOSE: Mixed reality (MR) simulations are increasingly used in medical training to provide safe, controllable, and repeatable practice environments. While visual fidelity (VF) and interaction fidelity (IF) are known to influence user experience (UX), their respective effects on...

Depressive symptoms in amyotrophic lateral sclerosis: associations with quality of life, disease progression and perceived social support—a German multicenter study

BACKGROUND: Amyotrophic Lateral Sclerosis (ALS) is a rapidly progressive, fatal neurodegenerative disease. Patients with ALS are at increased risk of developing depressive symptoms. A clearer understanding of the associations between depressive symptoms, disease progression, heal...
