SOCP-DistFlow Based Two-Stage Robust Scheduling of Shipboard Integrated Energy Systems Under Carbon Pricing

Existing and prospective maritime carbon-pricing regimes, together with uncertain renewable generation, complicate the low-carbon operation of shipboard integrated energy systems (SIES), particularly when network voltages and coupled electrical, heating, and cooling demands must...

A High-Accuracy human posture prediction based on Quasi-Distributed flexible FBG arrays and random forest algorithm

Human posture prediction has practical value in numerous fields such as motion analysis, rehabilitation medicine, and human–computer interaction. This study proposes a novel approach for human posture prediction, realized through a quasi-distributed sensor array based on flexibly...

Energy Transition Strategy and the Scale–Composition Association: How Fiscal Instruments Relate to Renewable-Energy Share, Energy Demand, and Decarbonization for Sustainable Development Across Developing and Developed Economies

National energy strategies increasingly treat renewable-capacity expansion as a proxy for decarbonization progress. This paper tests that proxy by separating energy-system change into two margins—composition (renewable share) and scale (energy demand)—and estimating how three fis...

The inequality of basic public services and the willingness to stay long-term of rural migrant workers at the county level: evidence from Beijing-Tianjin-Hebei in China

This study examines how county-level inequality in basic public services (IBPS) affects the willingness to stay (WTS) of rural migrant workers (RMWs) in China’s Beijing-Tianjin-Hebei region. Results indicate that IBPS positively affects the RMWs’ willingness to settle in counties...

HELO-APR: Enhancing Low-Resource Program Repair through Cross-Lingual Knowledge Transfer

Large Language Models (LLMs) perform well on automatic program repair (APR) for high-resource programming languages (HRPLs), but their effectiveness drops sharply in low-resource programming languages (LRPLs) due to the lack of sufficient verified buggy–fixed pairs for APR traini...

Enhanced Hydrogen Production via Surface Oxygen Vacancy Regulation in Element-Doped Ni/CeO2 Catalysts

Abstract Steam reforming of methane (SRM) for H2 production is a critically important industrial H2 production pathway that has attracted extensive research. However, catalyst deactivation and instability at high reaction temperatures and low water-to-methane ratios remain pressi...

Active-passive hybrid broadband vibration control based on maple-leaf-inspired biomimetic structures

Broadband vibration control remains a critical challenge in lightweight structural design. This study proposes a bio-inspired integrated approach combining a maple-leaf-inspired laminated structure with active-passive hybrid control to achieve effective vibration suppression acro...

Hierarchical graph reinforcement learning for coordinated dispatch and reconfiguration of active distribution networks

Traditional studies on active distribution networks often optimize operational dispatch and network topology reconfiguration in a decoupled manner, although the two decisions are strongly coupled through power-flow redistribution, controllable-device outputs, and network constrai...

Leveraging room-temperature plastic deformation for tailoring inorganic thermoelectrics

Mg 3 (Sb, Bi) 2 has emerged as a promising material due to its favorable combination of high thermoelectric performance and ductility. However, a key question remains regarding how plastic deformation affects its thermoelectric properties. Here we investigate the evolution of def...

Interfacial polymerization-based NF/LNF membranes for selective dye/salt fractionation: From dye properties and membrane design to industrial translation

Driven by the increasing demand for green and low-carbon manufacturing and the pursuit of near-zero liquid discharge (NZLD), the valorization of hypersaline textile wastewater streams through the simultaneous reclamation of high-purity salts, residual dyes, and purified water has...

Non-Destructive Testing Technology for Natural Gas Pipeline Wall Thickness Measurement: A Comprehensive Review

With the gradual increase in demand for natural gas, the scale of global natural gas pipeline (NGP) construction is also gradually increasing. However, with the gradual increase in NGP laying, the reduction in pipeline wall thickness is the main cause of major safety accidents. I...

Stochastic scheduling based formation control of underwater teleoperator with time-varying delay

Most, if not all, research in single-master-multiple-slave (SMMS) underwater teleoperator formation control has assumed that continuous-time signal transmission is available among master and slaves. Unfortunately, the inherent challenges posed by limited bandwidth and time-varyin...

Function-Switchable Superconducting-Spintronic Devices for Read-Protected Data Storage

Abstract Superconductivity and charge-to-spin conversion are both desirable for low-dissipation information processing, but they usually operate in different material platforms. Here we show that the p-orbital alloy In2Bi combines type-II superconductivity below 5.6 K with effici...

Fluorescence spectral identification of soil microplastics based on FA-IGWO-ELM

Microplastics are widespread contaminants in soil environments, creating a need for rapid and accurate methods for polymer identification. Fluorescence spectroscopy offers a sensitive, low-cost and nondestructive analytical route, but spectral overlap among soil–microplastic samp...
