Innovative Clinical Trial Approach for Evaluating Digital Medical Devices Under European Fast-Track Regulatory Frameworks. [PDF]
Stat MedABSTRACT To address patient demand for rapid access to innovative digital medical devices (DMDs), several health technology assessment (HTA) authorities in European Union countries provide transitional or provisional access and reimbursement pathways. These pathways are available when only incomplete clinical trial data are accessible, and significant ...

Angewandte Chemie International Edition, EarlyView.A new photochromic material was developed. Its on/off‐switchable absorption band is situated completely outside the human eye's visibility, in the near‐infrared (NIR) region, a feature never reported before. The photochromism mechanism in this aluminosilicate is elucidated by combining experimental as well as computational results, and the material's ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

Simulation numérique d'un bruleur à biogaz destiné aux moteurs Stirling
Revue des Énergies Renouvelables, 2022 The design of a biogas burner for Stirling engines depends on its ability to provide a sufficient heat which is not produced by conventional burners because of the limitation of the contact surface between flame-hot head and the low methane content in ...

Optimal subsampling for regression with mixed‐type predictors
Canadian Journal of Statistics, EarlyView.Abstract Subsampling has emerged as an appealing strategy to mitigate the computational and storage challenges imposed by large datasets. Recent subsampling techniques have shown notable computational gains for data dominated by numerical predictors. However, real‐world datasets frequently contain both numerical and categorical predictors.

Revisiting Fisher's n‐D statistical vision: From algebraic abstraction to modern visualization
Canadian Journal of Statistics, EarlyView.Abstract We revisit early foundational results in mathematical statistics derived by Ronald A. Fisher. They involve sampling distributions of statistics calculated from independent and identically distributed Normal observations, namely the root mean square deviation; the mean absolute deviation, conditional on already knowing the value of the root ...

Un outil de dimensionnement des filets pare-pierres : le logiciel ECRANS
Sciences, Eaux & Territoires, 2010 Les instabilités rocheuses figurent parmi les aléas rencontrés fréquemment en zone de montagne. Afin de réduire le risque associé, la stratégie dite passive vise à mettre en place des techniques de protection qui permettent de contrôler la trajectoire ...

Small, EarlyView.The silver nanoparticle morphologies are identified thanks to ab initio models, including original families of defects and complex motifs, compared to measurements provided at targeted sizes (309, 561, 742, and 923 atoms). The crossings between structures to within a few atoms have been predicted due to very accurate computational conditions, which are

Étude concernant l’effet de mise à la terre dans le système de protection liaison au neutre [PDF]
Bulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2009 La sécurité des consommateurs de l’énergie électrique fait partie des principales demandes de la Loi 10/95, concernant la qualité dans les bâtiments. Le risque d’un choc électrique doit être diminué en adoptant un système de protection basé sur un moyen ...
