Factors affecting the mean electrical axis of the heart in trained Thoroughbreds

Equine Veterinary Education, EarlyView.
Summary Background Assuming that the ventricular myocardium of horses is subjected to exercise‐induced hypertrophy, we hypothesised that the mean electrical axis (MEA) of the heart would change. Objectives To define a longitudinal study to detect any changes in the direction of the MEA in Thoroughbred horses using ECG.

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.

Single-Shot Phase Diversity Wavefront Sensing in Deep Turbulence via Metasurface Optics [PDF]

arXiv
Free-space optical communication (FSOC) systems offer high-bandwidth and secure communication with minimal capital costs. Adaptive optics (AO) are typically added to these systems to decrease atmospheric channel losses; however, the performance of traditional AO wavefront sensors degrades in long-range, deep turbulence conditions. Alternative wavefront
