Quantifying the Impact of Temporal and Spatial Heterogeneity in Turbulence on Bed‐Load Transport Over Vegetated Beds Under Wave‐Current Conditions

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Laboratory experiments measured velocity and bedload transport in vegetated channels under current‐dominated, combined wave‐current conditions. Waves and vegetation, respectively, introduced temporal and spatial heterogeneity in the velocity, which significantly impacted sediment transport rate.

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.

Placental insufficiency markers to assess the risk of non‐chromosomal genetic conditions in early‐onset fetal growth restriction

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 492-499, April 2026.
ABSTRACT Objectives To assess the value of placental insufficiency markers for estimating the risk of genetic anomalies in fetuses with isolated early‐onset fetal growth restriction (FGR), defined as an estimated fetal weight ≤ 3rd percentile diagnosed ≤ 28 + 6 weeks' gestation.

Validation of the granular temperature prediction of the kinetic theory of granular flow by particle image velocimetry and discrete particle model [PDF]

, 2004
In order to give a detailed description of the hydrodynamics in large industrial scale fluidized beds, continuum models are required. Continuum models often use the kinetic theory of granular flow (KTGF) to provide closure equations for the internal ...

Global Hydroclimatic Controls on Multithread River Dynamics

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Most large rivers in densely populated areas split flow into multiple channels, forming interconnected pathways called threads. Multithread rivers are sensitive to hydroclimatic changes, yet understanding their dynamics is challenging due to the lack of robust metrics to characterize their evolution.

Large Wood Retention in Forested River Corridors During Overbank Flood Events: Insights From Flume Experiments

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Understanding large wood (LW) dynamics on floodplains is important for closing wood budgets and predicting hazards associated with LW. We conducted 38 experiments in a fixed‐bed flume to examine how forest stand density (FSD), wood transport regime, and overbank flood magnitude affect floodplain LW retention.

A computational model for retinal haemodynamics under gravitational and postural variations

The Journal of Physiology, Volume 604, Issue 7, Page 2698-2716, 1 April 2026.
Abstract figure legend The haemodynamic impact of gravitational and postural changes on the retina, and its relevance to spaceflight associated neuro‐ocular syndrome (SANS), remains incompletely characterized. This study assesses retinal haemodynamics from upright to head‐down tilt using a lumped‐parameter model that dynamically couples intraocular ...
