Reconstruction of high-speed train bogie hunting oscillations via a CNN-BiLSTM framework

High-speed train bogie hunting waves exhibit strong nonstationary characteristics and often suffer from data loss. Traditional methods struggle to fit local transients, causing over-smoothing and information loss. To address this, a multi-scale spatio-temporal feature fusion mode...

Plastic flow at the gauge corner of the low rail in heavy-haul sharp curves: Field investigation and formation mechanism

Plastic flow is a common form of damage on the low rail of sharp curves in heavy-haul railways; however, its quantitative characterization, evolution, and formation mechanism remain to be systematically clarified. Based on long-term field measurements from an in-service sharp cur...

Finishing Touch via Metal Coordination: A Photoactivatable Organic Semiconducting Prodrug for Triply Synergistic Amplified Cancer Phototheranostics

ABSTRACT Photothermal therapy (PTT), photodynamic therapy (PDT), and NIR‑II fluorescence imaging are each compromised by tumor hypoxia, thermotolerance, and insufficient contrast, respectively, limiting the efficacy of integrated phototheranostics. To address these challenges, we...

A space-time boundary mapped collocation method based on tensor decomposition with adaptive temporal discretization for dynamic analyses of fluid-saturated porous media

A space-time boundary mapped collocation method, incorporating tensor decomposition and adaptive temporal discretization, is proposed for dynamic analysis of fluid-saturated porous media under moving loads. In this method, the time domain is treated as an additional spatial dimen...

RCA–RAP Hot-Mix Asphalt Mixtures: Mass–Volume Non-Equivalence and Recycled Binder Availability in Mix Design and Performance Interpretation

Combining recycled concrete aggregate (RCA) and reclaimed asphalt pavement (RAP) in hot-mix asphalt (HMA) creates a coupled aggregate–binder design problem. This review critically synthesizes RCA–RAP studies, supplemented by relevant single-material evidence, to clarify how mater...

Hybrid hypergraph networks for multimodal sequence data classification

Abstract Modeling temporal multimodal data requires both long-range temporal dependencies and cross-modal interactions to be represented. Existing approaches commonly model each modality separately and then apply shallow fusion, which can limit the representation of higher-order...

Static–dynamic reloading degradation and brittle-to-ductile failure transition of cyclically pre-damaged sandstone: A multiscale experimental study

Rock masses in underground engineering commonly experience cyclic disturbances induced by blasting, excavation, and seismic loading, which can generate persistent internal damage and strongly affect their subsequent reloading behavior. To clarify the unified mechanism governing t...

Microbial corrosion and mitigation of ductile iron pipes in drinking water distribution systems under alternating anoxic–aerobic conditions: Dynamic corrosion roles of functional bacteria

Microbiologically influenced corrosion (MIC) threatens the safety and durability of drinking water distribution systems (DWDS), while the effects of fluctuating redox conditions on microbial corrosion evolution remain unclear. In this study, an alternating anoxic–aerobic system w...

Phytic acid-copper coordination network-based composite membranes for simultaneous nanofiltration and broad-spectrum antimicrobial activity

The “trade-off” effect of membranes and biofouling are significant barriers to the advancement of membrane technology for nanofiltration. We suggest an innovative approach that is both eco-friendly and economically feasible to overcome these obstacles. Hydrophilic phytic acid (Ph...

Axial behavior of steel tubes strengthened with outer steel tube–concrete jackets

Hollow steel tube (HST) columns are widely used in engineering structures due to their high load-carrying efficiency and excellent ductility. However, strengthening is often required when functional upgrading is needed or when load demands increase. This study investigates the ax...
