AI in gastroenterology and hepatology A narrative review of applications, evidence maturity, and governance implications for Latin America

Artificial intelligence applications in gastroenterology and hepatology have been evaluated in gastrointestinal endoscopy, image interpretation, liver fibrosis risk assessment, hepatocellular carcinoma diagnosis, and initial referral assessment (authorization or request for addit...

Physician Portraits Built with AI from Their Clinical Searches: An Exploratory Evaluation

Administrative registries record who is licensed to practice medicine, but not how each physician practices. The search history a physician leaves in a clinical search engine is, by contrast, behavior recorded as it happens: what they searched, when, and how they phrased it. This...

Dynamics-based forward kinematics estimation for Stewart platform using unscented Kalman filter with extended actuator observations

This paper presents a dynamics-based approach for solving the forward kinematics problem of Stewart–Gough platforms using an Unscented Kalman Filter (UKF) with extended actuator observations. Unlike conventional methods that rely solely on geometric relationships or require addit...

The impact of global influence on peace and stability conditions in G20 countries

Peace, cooperation, and stable relations among nations are essential for maintaining global stability. This study applies Power Transition Theory (PTT) to examine how global factors influence peace and stability conditions among G20 countries. It uses 16 years of data (2008–2023)...
