Interaction Ritual Chain Theory-Based Immersive Interaction Design for Cultural Heritage

Immersive technologies offer new possibilities for cultural heritage, yet their potential to foster social interaction, emotional connections, and cultural identity at cognate heritage sites remains underexplored. Based on Interaction Ritual Chain (IRC) theory, this study develop...

Effect of Al 2 O 3 substitution for SiO 2 on fluorosilicate glass-ceramics fabricated from fluoride-containing sludge

Abstract The safe disposal and resource utilization of industrial fluoride-containing sludge represent a critical environmental challenge. In this study, high-performance fluorcanasite glass-ceramics were successfully synthesized from industrial sludge via a melt-quenching follow...

Homologous association learning network for gearbox fault diagnosis under time-varying speed conditions

Under time-varying speed conditions, vibration signals measured from rotating machinery, especially planetary gearboxes, are non-stationary, and fault features of the same category may drift across different speed ranges, thereby causing distribution mismatch among variable-speed...

Structure-Guided Hybrid GCN−Transformer Framework for Enzyme Optimal pH Prediction

Abstract Accurate prediction of enzyme optimal pH (pHopt) is fundamental to biocatalyst engineering, pharmaceutical development, and process optimization, yet developing a reliable computational method remains challenging. To address this limitation, we present trPHopt, which is...

Discovery and Manipulation of a Single Polaron in a Monolayer Mott Insulator

Abstract Polarons are quasiparticles composed of excess electrons and local lattice distortions that are crucial for understanding many-body physics. However, atomic-scale observation and manipulation of an intrinsic polaron in strongly correlated systems still remain elusive. He...

Seismic Performance of Prefabricated Segmental CFST Stiff Skeleton Bridge Pier: Experimental Investigation and Analysis Model

Abstract Prefabricated bridge piers provide benefits, including improved efficiency, high-quality construction, and minimized environmental impact. For bridges in mountainous areas in high seismic risk regions, large pier heights and high reinforcement ratios in the pier sections...

Orthogonally Polarized Excitons Under Quasi‐One‐Dimensional Moiré Confinement

ABSTRACT Moiré superlattices in two‐dimensional (2D) transition metal dichalcogenides (TMDs) offer a versatile platform to engineer excitonic states through interlayer coupling and symmetry control. While twist‐induced 2D moiré superlattices have been widely investigated, exciton...

Edge-Affinity-Directed Selective Pore-Mouth Sealing in Coal-Derived Hard Carbon for Stable and High-Capacity Sodium Storage

Abstract Sodium-ion batteries are attractive for large-scale energy storage, but the limited capacity of hard-carbon anodes constrains practical energy density. Increasing porosity can boost capacity, but typically enlarges the electrolyte-accessible surface, lowers the initial C...

An improved MADDPG-based framework for bidirectional safety management of construction robot interaction

Purpose Safety risks are particularly pronounced when multiple construction robots collaborate in complex construction environments. To enhance collaborative efficiency while ensuring operational safety, this study develops and evaluates, in a scaled simulation, a bidirectional s...

A goal-driven framework for carbon neutrality technology development

Abstract To achieve the mid-21st century carbon neutrality goal, accelerated carbon neutrality technology (CNT) innovation and deployment are needed, while most existing technologies and low-carbon systems fall short. Thus, a comprehensive CNT development roadmap is crucial for p...

LigPPFNet: A Lightweight Multimodal Fusion Method for Palmprint and Palm Vein Recognition

ABSTRACT Due to their high stability, accuracy, and security, palmprint and palm vein recognition offer significant advantages in biometric applications. However, traditional deep neural network models typically suffer from high computational complexity and large parameters, whic...

Thermomechanical Fully Coupled Nonorthogonal Elastoplastic Constitutive Model for Concrete

Abstract This study establishes a thermomechanical fully coupled nonorthogonal elastoplastic model, grounded in thermodynamic principles, to capture concrete’s strength degradation, plastic strain accumulation, and temperature-enhanced dilatancy under thermomechanical coupling. T...

Soft propaganda and the marginalized childcare policy in China

Childcare policies across all national contexts are deeply embedded within broader macroeconomic and political logics. China vividly illustrates this pattern: the transition from the single-child to the universal three-child policy signifies an increasingly growing and highly vis...

Ensemble fire probability prediction by integrating meteorological AI models with lightweight prediction networks

Wildfires pose persistent threats to ecosystems and human safety, making timely fire-risk assessment essential for disaster prevention and resource management. However, conventional wildfire early-warning approaches are often constrained by static fire-weather indices or machine-...

Vulnerability analysis of subsea immersed tunnels considering seismic motion ensembles with different spectral characteristics
