Differences Between the Unipolar Versus Bipolar Potential‐Based Activation Maps of Ventricular Premature Contractions Arising From Ventricular Outflow Tracts

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background The use of an automated annotation algorithm based on the maximal negative derivative of the unipolar potential (−dV/dTmax) for local activation timing in the ablation of outflow tract (OT) ventricular premature contractions (VPCs) remains controversial.

Quantitative analysis of human umbilical vein endothelial cell morphology and tubulogenesis

Journal of Microscopy, EarlyView.
Abstract Primary human umbilical vein endothelial cells can grow as both a monolayer in culture and also as a capillary‐like network making them an ideal model system in order to study vascular remodelling. Image‐based analysis can allow assessment of cell morphology and motility but is dependent on accurate cell segmentation which requires high ...

Model‐based aberration corrected microscopy inside a glass tube

Journal of Microscopy, EarlyView.
Abstract Microscope objectives achieve near diffraction‐limited performance only when used under the conditions they are designed for. In nonstandard geometries, such as thick cover slips or curved surfaces, severe aberrations arise, inevitably impairing high‐resolution imaging.

Complete‐coverage path planning for surface inspection of cable‐stayed bridge tower based on building information models and climbing robots

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Climbing robots present transformative potential for automated structural inspections, yet their deployment remains limited by the reliance on manual control due to the absence of effective environment perception and path‐planning solutions.
