Research on Disturbance Control of Electro-Hydraulic Servo Systems Based on Fractional-Order Sliding Mode Control

To improve the disturbance rejection performance of valve-controlled cylinder electro-hydraulic servo systems under external disturbances and load variations, this paper proposes a fractional-order sliding mode control (FOSMC) strategy. A system model with dual-inertia compensati...

Metasurface-Enhanced Sensing Platforms for Chemical, Biological, and Environmental Monitoring: Recent Advances and Future Perspectives

The growing demand for sensitive, selective, and rapid detection of trace analytes in complex matrices is driving the development of compact optical sensing platforms. Metasurfaces can strengthen light–matter interactions through subwavelength field confinement and resonance engi...

Interaction‐Matched Protonated Aminopyridine Additives for Highly Reversible Aqueous Zinc Metal Anodes and Zn–I 2 Batteries

ABSTRACT In aqueous zinc‐ion batteries, electrolyte additives stabilize Zn anodes through interfacial adsorption, suppressing corrosion and parasitic reactions while regulating Zn deposition. However, although enhanced zincophilicity and hydrophobicity improve interfacial protect...

The impact of family structure on the urban settlement intention of family migrants

Based on the dynamic monitoring data of the national migrants in 2012–2018, this study analyzes the factors influencing the settlement intentions of migrant workers from a family-oriented perspective. The results indicate that the intention of family migrants to settle is not hig...

Graph Learning for River Water Quality Forecasting: Advances in Hydrological Connectivity Representation, Dynamic Topology, and Physics-Informed Modeling

Graph neural networks are increasingly used for river water-quality forecasting because they can represent interactions among monitoring locations that conventional site-wise time-series models cannot capture. However, the usefulness of graph learning depends strongly on whether...

Dynamic Compressive Behavior and Numerical Simulation of a New Amorphous Alloy Fiber/Epoxy Composite

ABSTRACT This paper presents systematic research on dynamic compression behavior, damage mechanisms, and energy absorption mechanisms of a new CoFeSiB amorphous alloy fiber/epoxy composite (AAFEC) under four fiber orientations (FOs) and strain rates (SRs). The results demonstrate...
