Variations in Equitable Sociocultural Interactions Across Learning Activities in Pre-K to Third-Grade Classrooms

This study used secondary data collected in public elementary schools from 2016 to 2019 to examine variations in equitable sociocultural interactions, measured by the Assessing Classroom Sociocultural Equity Scale (ACSES), among classroom formats (e.g., whole group, small group),...

Neocortical long-range inhibition promotes cortical synchrony and sleep

Abstract Sleep and wakefulness are associated with distinct cortical patterns of rhythmic activity 1 . During low-arousal states such as slow-wave sleep, synchronous low-frequency rhythms dominate activity across widespread cortical regions. Although inhibitory neurons are increa...

Comparative Analysis of Ion and Electron Contributions to Ionospheric Ionization at Auroral and Subauroral Latitudes

Abstract Electron and proton precipitation into the nightside ionosphere is a key process in magnetosphere–ionosphere coupling. Although auroral electron precipitation at –10 keV is traditionally considered the main driver of auroral emissions, recent studies show that keV electr...
