A Within Canopy Deposition Model Capturing the Influence of Microplastic Size, Biological Cohesion, and Vegetation‐Generated Turbulence

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Laboratory experiments investigated how the presence of biofilm and particle size influenced deposition in both bare and vegetated channels. Both abiotic and biotic sediment beds were considered, with the biotic beds containing Extracellular Polymeric Substances (EPS). As current magnitude and turbulent kinetic energy increased, particles were

Verification of a Fluid–Structure Interaction Model for Aortic Stenosis Through Comparison With In Vitro Experiments

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 4, April 2026.
A patient‐specific Fluid–structure Interaction (FSI) model of aortic stenosis was verified against in vitro experiments using a mock‐loop circulatory system with patient‐specific calcified and non‐calcified valve models under varying flow conditions. The in vitro experiments were replicated in the FSI model.

Linking Remotely Sensed Hydromorphological Conditions With Biological Observations to Estimate Salmon Spawning Capacity

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Performing ecohydraulic assessments of salmon habitat is essential for planning and evaluating management actions. Current in situ and modelling approaches, although accurate, can be time‐consuming and expensive, which limits the areal extent of the study.

Is Doppler ultrasound useful for evaluating gestational trophoblastic disease?

Clinics
Doppler ultrasound is a non-invasive method for evaluating vascularization and is widely used in clinical practice. Gestational trophoblastic neoplasia includes a group of highly vascularized malignancies derived from placental cells.

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, Volume 73, Issue S2, Page S109-S116, April 2026.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...
