Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

Deep Learning‐Based Particle Tracking Velocimetry (PTV) for Spherical and Non‐Spherical Particles: Application to Sediment Transport

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Particle‐resolved measurements in physical experiments are crucial to the study of sediment transport. Conventional particle tracking velocimetry (PTV) relies on template matching of simple shapes via intensity thresholding and nearest‐neighbor linking.

Refinement of a Framework for Moving Aircraft River Velocimetry (MARV) and Application to Particle Tracking Along Alaskan Rivers

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow‐up study, we used data from two new sites, one with a more complex morphology and the other with a lower suspended sediment concentration, to provide further evidence that ...

Standardization of In Vitro Evaluation of Extracorporeal Life Support (ECLS) Devices for Research and Development

Artificial Organs, Volume 50, Issue 5, Page 674-688, May 2026.
ABSTRACT Extracorporeal life support (ECLS) technology has witnessed remarkable advancements during the last decades. However, further research and development of devices are required to increase, for example, performance‐efficiency, hemocompatibility, and long‐term stability.
