Quantitative discrimination of debonding defects and non-debonding defects in coated propellant grain based on shearography

During the production of coated propellant grains, micro-bubble defects inevitably form within the liner layer. Although these non-debonding defects do not compromise structural integrity, current shearography-based non-destructive testing cannot reliably distinguish them from cr...

Peer hypocrisy and corporate philanthropic giving

Purpose This paper aims to examine whether the prevalence of peer hypocrisy among industry counterparts is associated with reduced corporate philanthropic giving by focal firms and explore the pathways through which this association arises. Design/methodology/approach Using a pan...

External factors of hotel philanthropic giving: Peer effects and fiscal stress

This study investigates two underexplored external determinants of hotel corporate giving (CG): peer effects and fiscal stress. Drawing on institutional theory, we analyze panel data from publicly listed Chinese hotel companies (2003–2022) using Tobit regression models to accommo...

Solid-State-Sintered Silicon Carbide Reactor for High-Throughput Continuous-Flow Synthesis of Dodecylbenzene Sulfonic Acid

Abstract It is still a challenge to achieve a continuous-flow reactor with high heat transfer and corrosion resistance for sulfonation reactions. Herein, a solid-state-sintered silicon carbide (SiC) reactor has been developed and applied to the synthesis of dodecylbenzene sulfoni...

Digital technology application breadth, depth and international performance: the moderating role of digital services trade barriers

Purpose This study aims to investigate how digital technology application breadth (DTAB) and digital technology application depth (DTAD) affect firms’ international performance and how digital services trade barriers (DSTB) moderate the effects. Design/methodology/approach Drawin...

High-Sensitivity Remote Radiation Detection Enabled by CsPbBr3 Quantum-Dot-Doped Polymer–Silica Fiber with Core-Emitting and Cladding-Dominated Transmission

Abstract Metal halide perovskite quantum dots (PQDs), particularly CsPbBr3 QDs, are promising luminescent materials for radiation detection owing to their strong radiation absorption and high photoluminescence efficiency. However, the spectral overlap between absorption and emiss...

Rec-PdM: Decision-calibrated recursive multi-agent systems for uncertainty-aware prescriptive maintenance in smart manufacturing

Predictive maintenance creates industrial value only when uncertain health evidence leads to an appropriate intervention under asymmetric failure costs and operational constraints. We present Rec-PdM, a decision-calibrated recursive multi-agent system for uncertainty-aware prescr...

Breaking the dilemma of trajectory imbalance and sample scarcity: A Multi-Behavior Prototype Siamese Network for vessel type recognition

Vessel type recognition is at the core of intelligent maritime monitoring. Real-world AIS datasets follow a long-tailed distribution, giving rise to two coupled challenges: class imbalance and sample scarcity in minority vessel categories. Samples from majority classes dominate t...

Robust Ordered-Risk Assessment via Physics-Informed Synthetic Data Generation and TA-DE-ELM

Ordered-risk assessment is a safety-critical learning problem in which delayed or biased risk estimation can affect prioritization and response planning. Existing expert-knowledge and data-driven approaches face a trade-off among transparent indicator design, nonlinear representa...

Ultrahigh On/Off Ratio Oxide Transistors via Noncoplanar Schottky–Ohmic Contacts

Abstract Simultaneously balancing high mobility and ultra-low leakage current is a major challenge for metal-oxide thin-film transistors (TFTs) in ultra-low-power applications. Herein, we construct a high-performance InGaZnO/InGaO/InGaZnO tri-layer TFT based on a noncoplanar Scho...

Direct evaporation of single-crystal metal contacts for 2D semiconductors

Metal contacts remain one of the key bottlenecks in two-dimensional (2D) semiconductor electronics. We developed an atomic-scale step-by-step evaporation method to directly grow single-crystal metals on monolayer semiconductors with clean interfaces. This method accesses a distin...
