Governing linguistic unity and diversity: ideological legitimation and philosophical repertoires in Chinese language planning

Language governance in multilingual societies often involves negotiating tensions between linguistic unity and diversity. In the Chinese context, language planning has long drawn on multiple intellectual traditions that provide justificatory resources through which such tensions...

Unravelling the links between stress perception, anxiety, and smartphone addiction in adolescents: A two-wave longitudinal study

BACKGROUND: The rise of smartphone addiction among adolescents, especially in China where internet and mobile usage are notably high, has prompted concerns about its impacts on mental health and social skills. Previous research has mainly used cross-sectional approaches, which ar...

Developing meta-FM machine learning model with application for personalized language learning environment

A meta-pretrained factorization machine (FM) framework, termed Meta-FM, is proposed to address the cold-start problem in personalized learning path generation for middle-school foreign language education. The framework further introduces a cross-modal feature augmentation module...

A Deep Model Framework for Morphological Trait Imputation Across Taxonomic Groups

ABSTRACT Incomplete morphological trait data pose major hurdles for trait‐based analyses, particularly when missing values, multicollinearity, and sparse sampling constrain inference. These issues limit our ability to quantify trait variation and explore broad patterns of functio...

Characterization of Chromosomal Structural Polymorphism in Roegneria nutans from the Western Sichuan Plateau, China Based on Tandem Repeat Sequences

Roegneria nutans, a premium grass on Western Sichuan Plateau, China, is vital for ecological stability and pastoral security. Studying its chromosomal architecture and environmental correlations lays a foundation for Roegneria genetic evolution research. This study used genomic i...

Dissymmetrical planar gratings enabled actively chiral perfect absorber

Chiral perfect absorbers (CPAs) can completely absorb one kind of circularly-polarized light while reflecting the other, and have potential applications in fields such as chiral Fabry–Pérot cavity, chiral light emission, and chiral biosensors. In this work, we present a high-perf...

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...

Synthesis of theNatural Product Berberine

Abstract In this work, the synthesis of berberine was accomplished through three distinct routes. The key innovation lies in replacing the traditional intermediate piperonylamine with 2,3-dimethoxybenzylamine, thereby circumventing the lengthy and low-yielding steps of the interm...

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...
