Demand-Sensitive Time Allocation in Digital Reading: Evidence from 25 Education Systems

Digital assessments record item-visit durations and revisiting. These traces can reveal responses to task difficulty, but achievement associations do not establish stable person-level measures. We linked digitalPIRLS 2021 process, response, and achievement data across 25 educatio...

Beyond Mean Score Differences: Home Language and the Interpretation of Cognitive Test Performance in China

Large-scale surveys often use cognitive test total scores to describe group differences, but the construct meaning of such scores depends on task content, administration, language experience, and opportunities to learn. The China Family Panel Studies (CFPS) word test is an oral M...

Integrated Metabolomic and Transcriptomic Analysis Reveals Tissue-Specific Secondary Metabolic Differentiation and Indole Alkaloid Accumulation in Evodia rutaecarpa

Evodia rutaecarpa is a valuable medicinal plant, yet its non-medicinal tissues remain largely underexplored. Here, we integrated ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS)-based widely targeted metabolomics and RNA sequencing (RNA-seq) transcrip...

A Field-Theoretic Reading of Transformer Probing Structure: QKV Three-Channel Division × q Two-Layer × Final-Layer Immunity

The query-key-value (QKV) three-channel architecture is the core of the attention mechanism, yet a unified reading of the functional division among these channels within the probing structure remains lacking. Using a field-theoretic framework (materials as density-clustering fiel...

Density Clustering Matrix: Standard Matrix as the δ-Aligned Subspace Special Case

Field Domain Mathematics posits that numbers are density clusterings in space. This paper defines the Density Clustering Matrix with elements as density clustering points, addition as Merge and multiplication as Resonance. Key finding: standard matrix is an exact special case on...
