A review of empirical dam breach models

open access: yesRiver, Volume 5, Issue 3, Page 328-350, August 2026.
Abstract Dam breach modelling is central to flood risk assessment, yet the empirical models commonly used for estimating breach parameters display considerable variability and uncertainty. This review evaluates the performance of widely applied empirical dam breach models and identifies those that consistently show lower uncertainty, such as the ...

A Semi‐Resolved LES‐DEM Framework for Turbulent Bedload Transport From Saltation to Sheet‐Flow Regimes

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract Bedload transport widely occurs in natural environments and encompasses flow regimes from saltation to sheet‐flow, with markedly different fluid‐particle interaction characteristics. Understanding these mechanisms requires a numerical tool capable of capturing both the turbulence and fluid‐particle interactions, for which challenges exist due ...

Shaping the Flow: Impact of Blade Shape on Performance and Hemocompatibility in Rotodynamic Blood Pumps

open access: yesArtificial Organs, Volume 50, Issue 10, Page 1360-1371, October 2026.
Blade shapes (leading‐edge geometry and thickness) in rotodynamic blood pumps were systematically evaluated. Thinner blades improve pump efficiency by reducing blockage effects, while neither blade thickness nor leading‐edge geometry shows clear hemocompatibility benefits. Overall, blade shape has a limited impact on hemocompatibility, indicating it is

An Optimized Multi‐Stage Drainage Cannula Design for Venoarterial Extracorporeal Membrane Oxygenation

open access: yesArtificial Organs, Volume 50, Issue 10, Page 1372-1383, October 2026.
This study utilized an extensive optimization involving n = 540 design of experiments to produce a superior drainage cannula design. Compared to the clinically used Maquet model, our optimized design demonstrated reduced blood stagnation volumes, increased cannula tip velocities, and higher upper body drainage, potentially minimizing risk of thrombosis

Pediatric Guillain‐Barré Syndrome Post Organ Transplant: Acute and Chronic Complication Requiring High Index of Suspicion

open access: yesPediatric Transplantation, Volume 30, Issue 10, October 2026.
ABSTRACT Background Guillain‐Barré syndrome (GBS) is an acute, immune‐mediated polyradiculoneuropathy most often triggered by infections such as Campylobacter jejuni, Epstein–Barr virus (EBV), or cytomegalovirus (CMV). Although transplant‐associated GBS is recognized in adults, it remains rare in pediatric recipients, and distinguishing immune‐mediated
