Evaluation for Gigacycle Fatigue Strength of Alloy Tool Steel

Journal of the Society of Materials Science, Japan, 2005
Ultrasonic fatigue tests were conducted with the specimens cut from LL and TT orientations of alloy tool steel. All fracture origins were defects inside the materials or very near surface. The S-N curves were monotonously decreasing slope as Nf increases.

Artificial Intelligence–Based Surgical Phase Analysis Enables Objective Assessment of Surgeon Skill in Robotic Distal Gastrectomy: A Multicenter Study

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Aim Artificial intelligence (AI)–based surgical video analysis can automate time‐consuming manual assessments and enable objective characterization of surgical workflows. We aimed to construct a large, multicenter, fully annotated dataset of robotic distal gastrectomy (RDG) videos and evaluate the feasibility and performance of an AI model for
