Vendor‐Agnostic Vision Transformer‐Based Artificial Intelligence for Peroral Cholangioscopy: Diagnostic Performance in Biliary Strictures Compared With Convolutional Neural Networks and Endoscopists

Digestive Endoscopy, EarlyView.
ABSTRACT Objectives Accurate diagnosis of biliary strictures remains challenging. This study aimed to develop an artificial intelligence (AI) system for peroral cholangioscopy (POCS) using a Vision Transformer (ViT) architecture and to evaluate its performance compared to different vendor devices, conventional convolutional neural networks (CNNs), and ...

Maximal subgroups in torsion branch groups

We study the maximal subgroups of branch groups and obtain a criterion that ensures that certain spinal groups are contained in the class $\mathcal{MF}$ of groups with all maximal subgroups of finite index. This allows us to construct branch groups within $\mathcal{MF}$ exhibiting novel properties, for example groups that possess non-normal maximal ...

Accuracy of Robotic Computer‐Assisted Implant Surgery Combined With Transcrestal Sinus Floor Elevation for Single‐Tooth Implants: A Retrospective Case Series

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To evaluate the accuracy and safety of robotic computer‐assisted implant surgery (r‐CAIS) for transcrestal sinus floor elevation (TSFE) in single‐tooth implant placement. Materials and Methods In this retrospective case series, we assessed the positional accuracy of r‐CAIS combined with TSFE in the posterior maxilla.
