Phenothiazine-Functionalized Triazine-Based Covalent Organic Frameworks for Efficient Photocatalytic Organic Synthesis

Abstract In this work, we present a donor–acceptor molecular engineering strategy in which three electron-donating moieties including benzene, triphenylamine, and phenothiazine are condensed with electron-deficient triazine monomers via Schiff-base reaction to furnish three cryst...

A fine-grained bidirectional multi-scale network for extreme-aspect-ratio bamboo slip character detection

Automated bamboo slip character detection supports cultural heritage digitization, but it remains difficult because excavated manuscripts contain dense, slender, fragmented, and degraded characters. Faded ink, wood grain, cracks, and stains often resemble genuine strokes, causing...

Assessment of Deterioration Characteristics of Solid Waste-Based Binder-Stabilized Laterite Under Multiple Environmental Factors Based on Micro-Drilling Resistance

Solid waste-based binder-stabilized laterite is prone to progressive deterioration under multiple coupled environmental factors in practical engineering applications. Conventional compression and direct shear tests fail to accurately characterize the gradient deterioration patter...

Seawater sea-sand concrete beams reinforced with steel–FRP composite bars under coupled seawater immersion and sustained load: Flexural behavior and degradation modeling

Steel–fiber reinforced polymer (FRP) composite bars (SFCBs) exhibit high post-yield stiffness and good corrosion resistance, making them a reliable form of reinforcement for seawater sea-sand concrete (SWSSC). Nevertheless, the durability of SFCB-reinforced SWSSC beams has not be...

Multivariable Determinants of Indoor PM2.5 and Infiltration Factors in 48 Residential Buildings Across Eight Northern Chinese Cities: A Seasonal Monitoring and Linear Mixed-Effects Modelling Study

Indoor exposure to fine particulate matter (PM2.5) is a major environmental-health concern in Northern China, where severe ambient pollution, coal-based district heating and diverse residential building stocks coexist. Previous studies have been constrained by small numbers of in...

A contrastive learning framework with HuBERT for violin music emotion recognition

Music emotion recognition (MER) is essential for affective computing and intelligent recommendation, yet solo instrumental music—particularly violin performance—remains underexplored due to the absence of lyrics, the subtlety of emotional expression, and the lack of dedicated dat...

Synergistic Grain Boundary and Phonon Engineering Enables Ultrahigh Thermoelectric Performance in Mg 3 (Sb, Bi) 2 ‐Based Materials

ABSTRACT Thermoelectric Mg 3 (Sb, Bi) 2 has emerged as a rising star in virtue of its promising thermoelectric performance and abundant constituent elements. However, its practical application is hindered by challenges in synthesis and the strong coupling between electrical and t...

Data-Driven Screening of Particle Grading for Dense Granular Packing

Optimizing particle grading for dense granular packing remains challenging because the formulation space expands rapidly with increasing particle-size complexity, while direct evaluation using the discrete element method (DEM) is computationally expensive. In this work, a data-dr...

Copper-Catalyzed Divergent1,4-Polyhaloalkylcyanationof 1,3-Enynes

Abstract We report a switchable copper-catalyzed divergent 1,4-polyhaloalkylcyanation of 1,3-enynes to construct a series of polyhalogenated allenes with high chemoselectivity and regioselectivity. The 1,4-dichloromethylcyanation of 1,3-enynes is realized by merging aminoalkyl ra...

Effects of sleep quality on the offline storage state of visual working memory

Abstract Objective Visual working memory (VWM) is a core cognitive function in humans, which enables flexible and efficient storage of visual information from complex contexts into either online or offline states in accordance with current task demands. Among these two states, th...
