Hydrodynamic Performance of a Novel Wave‐Driven Pump for Artificial Downwelling of Surface Water in Coastal Waters

Engineering Reports, Volume 8, Issue 7, July 2026.
Diagram of the novel wave‐driven pump system: (a) components; (b) working principle; (c) buoy subsystem; (d) pipe subsystem. ABSTRACT Artificial downwelling of oxygen‐rich surface water (ORSW) has recently gained interest among environmental engineers as a potential solution for alleviating hypoxia in coastal waters.

Real‐Time 3‐Dimensional Echocardiographic Assessment of Effective Regurgitant Orifice Area in Dogs With Myxomatous Mitral Valve Disease

Journal of Veterinary Internal Medicine, 2017
Background Effective regurgitant orifice area (EROA), calculated from the vena contracta width (VCW) as the narrowest portion of the proximal regurgitant jet, might be used to estimate severity of mitral regurgitation. However, this simplified assumption

A Non‐Reciprocal Architected Porous Medium

Advanced Functional Materials, Volume 36, Issue 47, 11 June 2026.
ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

“Diagnostic Performance of Artificial Intelligence in Evaluating Tricuspid Regurgitation: A Systematic Review and Meta‐Analysis”

Clinical Cardiology, Volume 49, Issue 6, June 2026.
Artificial intelligence demonstrates strong diagnostic accuracy for detecting tricuspid regurgitation, particularly with echocardiography‐based models. Despite promising performance, substantial heterogeneity and limited external validation highlight the need for prospective, multicenter studies before routine clinical implementation.

Quantification of mitral and aortic regurgitation using high pulse repetition frequency three-dimensional color Doppler [PDF]

, 2016
Det er utviklet og patentert en tredimensjonal ultralyd Doppler metode (multibeam high pulse repetition frequency color Doppler eller MULDO) for kvantitering av klaffelekkasjer. Ved hjelp av Doppler kan blodstrøms hastigheter måles. Ved en klaffelekkasje

Effects of Rotor-Rotor Interaction on the Wake Structure and Thrust Generation of a Quadrotor Unmanned Aerial Vehicle

IEEE Access, 2021
In this paper, the effects of rotor-rotor interaction on the wake structure and thrust generation of a quadrotor unmanned aerial vehicle (UAV) are experimentally investigated in the rotor tip Reynolds number range of 34000 – 54000. The interaction

Mitral regurgitation detection and central/eccentric classification using transformer‐based deep learning in multi‐view echocardiography

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background Fully automated diagnostic echocardiography allows for broader screening, earlier diagnosis for patients with mitral regurgitation (MR). This feasibility study developed a deep learning (DL) framework to automatically detect MR in echocardiography videos and classify regurgitation samples into central or eccentric regurgitation ...
