Predicting Equilibrium Bed Morphology of Large‐Scale Meandering Rivers Using a Novel LES‐Trained Machine Learning Approach

Journal of Advances in Modeling Earth Systems
Flood‐induced deformation of the bed topography of fluvial meandering rivers could lead to riverbank displacement, infrastructure failure, and the propagation of scour and deposition features.

Modulation of miR‐23b Wnt/β‐catenin Axis Strengthens Endothelial Barrier Properties

Advanced Science, EarlyView.
Early blood‐brain barrier (BBB) disruption contributes to stroke and CNS disease pathology. miR‐23b was identified as a regulator of BBB integrity in brain endothelial cells. Inhibition of miR‐23b enhanced barrier‐associated properties, promoted repair‐related signaling, and reduced BBB leakage in experimental stroke models, supporting further ...

A Numerical Approach to Analyzing Shallow Flows over Rough Surfaces

Fluids
The hydraulic characteristics (such as velocity profiles, near-bed velocity profile, bed shear stress, and resistance coefficients) of shallow flows over rough surfaces were investigated using numerical simulations.

Engineering Immunoregenerative Therapy via an Immunomodulatory Binary Pharmacology Hydrogel Depot for Prolonged Allograft Survival

Advanced Science, EarlyView.
An immunomodulatory hydrogel (iGEL) forms spontaneously upon subcutaneous injection, acting as a tissue‐adhesive depot. It releases anti‐rejection and regenerative agents in response to inflammation, suppressing T‐cell activity, promoting vascular repair, and restoring allograft function without systemic immunosuppression.

Effect of submerged vegetation on hydraulic resistance of ice-covered flows

International Journal of Sediment Research
Understanding the hydraulic resistance is vital for river engineering projects that include the installation of in-stream infrastructure, such as bridge abutments, which directly impact flow dynamics and sediment transport.

Application of Thermal Shear Stress Gauge in Study on Shear Stress Measurement on Underwater Bed Surface

Procedia Engineering, 2015
AbstractAlthough bed shear stress is one of the important ways to research the basic theory of sediment movement under the action of complex hydrodynamic force, the effective method for measurement of bed shear stress hasn’t formed yet. By application of the new micro-nanotechnology-based thermal shear stress gauge, this paper experimentally researches

Sustainable Fabrication of Tailored Bone Substitutes: From High‐Throughput Scaffold Manufacturing, Scaled‐Up HMSC Expansion to Dynamic Cultivation in a Perfusion Bioreactor

Advanced Science, EarlyView.
ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...

Sodium Ascorbate‐Accelerated Gelling Hydrogels With Rapid Self‐Mineralized Capacity for Chronic Wounds

Advanced Science, EarlyView.
An immunoregulatory hydrogel based on sodium ascorbate (SA)‐accelerated gelation and in situ self‐mineralization is prepared here. Such a hydrogel is constructed by mixing benzaldehyde‐ and cyanoacetate‐functionalized dextran with silver nitrate (AgNO3) and SA, enabling the ultrafast solidification and in situ self‐mineralization of silver ...
