Catchment Hysteresis From Pathway Branching and Storage Trapping: A Two‐Parameter Mittag‐Leffler Closure and Its Application to the Great Catchment Hysteresis Challenge

Hydrological Processes, Volume 40, Issue 10, October 2026.
Answering the great catchment hysteresis challenge, we derive a catchment closure whose memory kernel follows from counting flow pathways and measuring how long water is detained. Applied to four Cumbrian micro‐catchments, it shows that the observed hysteresis index conflates event retention with genuine memory, and separating them weakens the inferred

Three‐Dimensional Optical and Computational Reconstruction of Colloidal Electrokinetic Flows via Multiplane Imaging and Multiscale Modeling

Small, Volume 22, Issue 58, 16 October 2026.
Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...

Shape optimization for stationary Navier-Stokes equations [PDF]

, 2009
This work discusses geometric optimization problems governed by stationary Navier-Stokes equations. Optimal domains are proved to exist under the assumption that the family of admissible domains is bounded and satisfies the Lipschitz condition with a ...

Deep Learning‐Based Fusion of Hydrodynamic Model and Remote Sensing Observation for Mapping the Inundation Dynamics in Large Wetlands Under Changing Environment

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Wetlands play a crucial role in maintaining the global ecosystem balance, and determining the inundation dynamics is of great significance for understanding wetland ecosystems. Hydrodynamic models are effective tools for mapping the inundation dynamics; however, they are affected by uncertainties arising from environmental changes, including ...

Qualitative Properties of the Solution of a Conjugate Problem of Thermal Convection

Учёные записки Казанского университета: Серия Физико-математические науки
The joint convection of two viscous heat-conducting liquids in a three-dimensional layer bounded by flat solid walls was studied. The upper wall is thermally insulated, and the lower wall has a non-stationary temperature field. The liquids are immiscible

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

Water 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 ...

Non-isothermal axial flow of a rarefied gas between two coaxial cylinders

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2017
A stationary problem of heat transfer in a rarefied gas confined between two coaxial cylinders is presented. The two cylinders are maintained at two different constant temperatures, so that a radial temperature gradient is created.

Enhancing stroke risk stratification in atrial fibrillation through non‐Newtonian blood modelling and Gaussian process emulation

The Journal of Physiology, Volume 604, Issue 19, Page 8050-8068, 1 October 2026.
Abstract figure legend Non‐Newtonian modelling and GPEs for stroke risk in atrial fibrilation patients. Abstract Atrial fibrillation (AF) is the most common heart arrhythmia, linked to a five‐fold increase in stroke risk. The left atrial appendage (LAA), prone to blood stasis, is a common thrombus formation site in AF patients.
