From protogalaxy through thick and thin: Why did the Milky Way evolve in three kinematic phases?

Abstract APOGEE and Gaia data suggest the Milky Way’s kinematic structure evolved through three distinct phases: a disordered protogalaxy, which ‘spun up’ into a thick stellar disk, and then ‘cooled down’ to a final cold, thin stellar disk. We use a suite of FIRE-2 cosmological z...

Core-grammatical innovation in real time: radical and rapid constructionalization in Chinese

Abstract Recent research in Diachronic Construction Grammar and Creative Construction Grammar has begun to uncover nongradual cases of linguistic creativity. Two gaps nevertheless remain: the scarcity of documented cases of radical and rapid innovation in core grammar, and the ne...

Changes in alcohol-consumption frequency and factors associated with the magnitude of decreases during the COVID-19 pandemic: a nationally representative cross-sectional survey in Thailand

We described changes in alcohol-consumption frequency among current drinkers in Thailand during the COVID-19 pandemic and examined factors associated with a larger decrease among those who reduced their drinking frequency. We analysed a nationally representative face-to-face cros...

Three-million-year pulse: Pace and processes of Late Jurassic magmatism in the Sierra Nevada arc

Continental arcs commonly experience brief, high-flux magmatic pulses, and the Late Jurassic Sierra Nevada arc records one such event as a compositionally diverse magmatic system that includes highly silicic plutonic, hypabyssal, and volcanic rocks, associated cumulate gabbros, a...

Adult Attachment Predicts Parental Empathy: Evidence Across Four Samples of Parents of Children From Preschool Through Middle Childhood

Extensive research points to the importance of adult attachment in predicting empathy, but little research has examined the role of attachment in shaping adults’ empathy specifically for their children. This paper examines how adult attachment avoidance (discomfort with emotional...

PyQuiverHS: A Web Tool for Computing Isotope Effects

ABSTRACT Predicting isotope effects using electronic structure calculations is widely done, but current software options can present a barrier for some chemists, depending upon their needs and software/programming proficiency. Building upon existing code bases, we have developed...
