Real‐Time Vision System for Estimating Magnetic Compass Needle Oscillation Using Deep Learning

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
This study presents a low‐cost, vision‐based system for measuring compass needle oscillation. The system uses YOLO11s to detect the needle's pivot and tip in real time. Angle‐time data is tracked and fitted to extract oscillation parameters. The method is fast, accurate, and suitable for embedded navigation systems. ABSTRACT Compass needle oscillations

Coronary Artery Blood Flow Imaging Using 3D Flow MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 3, Page 1545-1559, March 2026.
ABSTRACT Purpose In this work, a 3D phase contrast (PC) technique is presented, which enables flow velocity measurements in three spatial directions, simultaneously covering the proximal left (LCA) and right (RCA) coronary arteries and yielding both morphological and flow information.

Advances in Rapid Nucleic Acid Diagnostics for Hepatitis B and C Viruses: A Comprehensive Review

open access: yesReviews in Medical Virology, Volume 36, Issue 2, March 2026.
ABSTRACT Chronic viral hepatitis, predominantly caused by HBV and HCV infections, remains a major global health burden and a leading cause of cirrhosis, hepatocellular carcinoma (HCC), and liver‐related mortality. Achieving the World Health Organisation (WHO) target of diagnosing 90% of HBV and HCV infections by 2030 necessitates a fundamental ...

Review of Amino Acid Foliar Application as a Stress Mitigation Strategy: Unraveling the Protective Mechanisms Against Abiotic Stress

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT The foliar application of amino acids offers a promising strategy to mitigate multiple abiotic stresses—drought, salinity, heat and heavy metals—by enhancing plant physiological, biochemical and molecular responses. This review synthesises recent advances in understanding how external amino acids function as bio‐stimulants, focusing on ...
