Weak Acceptors Abnormally Reinforce Urethane Networks while Enabling Glassy-State Healability

Abstract Hydrogen bonds are versatile motifs for designing repairable materials. The current preconception is that while weak hydrogen bonds lead to rapid exchanging dynamics beneficial for healing, they compromise mechanical properties by reducing the overall cohesion of the mat...

Dynamic reconfigurable metamaterials for coordinated heat and charge transport

Coordinated control of coupled heat and charge transport is fundamental to advanced thermoelectric energy conversion and management. Existing thermoelectric metamaterials are largely limited to static or steady-state functionalities. While spatiotemporal modulation has enabled dy...

Equivalence relations derived from $U$- and $V$-partial orders on bounded lattices: different neutral and zero elements perspective

This paper investigates the equivalence relations and algebraic structures induced by $U$-partial and $V$-partial orders on bounded lattices, respectively, with respect to the different neutral and zero elements. The study begins by presenting the equivalence classes associated w...

Solvent-Free Bubbling Extraction Mass Spectrometryfor Ultrasensitive, Size-Independent Detection of Microplastics inWater

Abstract Ultratrace microplastics (MPs) in aquatic environments are a growing problem for ecosystems and human health, yet their reliable detection at subng/L levels with sub-100 nm particle sizes remains a substantial analytical challenge. Herein, we introduce a solvent-free and...

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...

Adaptive-threshold max-SVM model with progressive-iterative algorithm for high-dimensional data classification and feature selection

Purpose Support vector machines have been progressively refined in existing research, but there are still certain limitations in feature selection for high-dimensional data. Design/methodology/approach This paper proposes an adaptive-threshold max-SVM model, which seeks to improv...

Root traits are strongly associated with nitrogen uptake efficiency in contrasting rapeseed genotypes

Abstract Screening the higher nitrogen (N) uptake efficiency (NUpE) rapeseed ( Brassica napus L.) genotype (N-efficient-genotype) and exploring the N efficient uptake mechanism could be an ideal way to meet the environmentally use of valuable N and the increasing demand for edibl...

Digitally 'Living' Preservation of Endangered Cultural Soundscapes: From Sampling and Spatial Audio Reconstruction to Interactive Narrative Design

Under the dual pressures of global cultural homogenization and intergenerational transmission rupture, endangered cultural soundscapes are disappearing at an unprecedented rate. Living sonic texts—such as ritual songs, oral dialects, and festival acoustics—that carry collective m...
