Direct Numerical Simulation of Magnetohydrodynamic Slip‐Flow Past a Stretching Surface Using Physics‐Informed Neural Network

Heat Transfer, EarlyView.
ABSTRACT Traditional numerical methods, such as finite difference methods (FDM), finite element methods (FEM), and spectral methods, often face meshing challenges and high computational cost for solving nonlinear coupled differential equations. Machine learning techniques, specifically Physics‐informed machine learning, address these obstacles by ...

Operating Capacity, Pricing and Supply Elasticity in Container Shipping Markets

International Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the channels through which changes in operating capacity influence freight rates in the container shipping market using a novel dataset to create an operating capacity index at the shipping‐route level. Our analysis reveals that when supply elasticity is low, an increase in operating capacity tends to drive freight rates upward,

Beyond a Conduit: The Evolution of Functional Biliary Stents From Active Intervention to Enabling Platforms

iNew Medicine, EarlyView.
This review traces the evolution of functional biliary stents, outlining the paradigm shift from “active intervention” strategies that target stent failure to next‐generation “enabling platforms.” These platforms leverage biodegradable materials, 3D/4D printing, and smart sensors to achieve personalized, regenerative, and theranostic solutions ...
