Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

open access: yesHigh Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

MIDAS: a quantitative framework for high‐energy diffraction microscopy. Part II: accuracy, robustness and best practices

open access: yesActa Crystallographica Section A, EarlyView.
This paper experimentally establishes the accuracy, robustness and performance limits of the high‐energy diffraction microscopy data reduction methodology. Using dedicated far‐field and near‐field datasets, it quantifies the influence of key analysis parameters, demonstrates computational efficiency, and establishes a framework of best practices to ...

Mixed Super‐Circles

open access: yesComputer Graphics Forum, EarlyView.
Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

Clinical Applicability of Artificial Intelligence–Driven Implant Planning and Surgical Guide Design in the Maxillary Esthetic Zone: A Registry‐Based Cohort Study

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives This study evaluated the accuracy, time efficiency, and workflow consistency of artificial intelligence (AI)‐assisted versus human expert (HI) implant planning in the esthetic anterior maxilla. Material and Methods Thirty‐five single‐tooth anterior maxillary cases with paired cone beam computed tomography (CBCT) and intraoral scans (

Three‐dimensional digital quantitative analysis of periodontal and peri‐implant phenotype—A narrative review

open access: yesPeriodontology 2000, EarlyView.
Abstract 3D digital evaluation of the periodontal and peri‐implant tissue, including CBCT, intraoral scanning, optical surface scanning, and ultrasonography, is being used in the clinical arena with increasing frequency. Thus, to validate the utilization of 3D digital analysis for this purpose, a critical evaluation of the reliability of digital ...
