Data-driven Modeling of Telluric Features and Stellar Variability with StellarSpectraObservationFitting.jl

Abstract A significant barrier to achieving the radial velocity (RV) measurement accuracy and precision required to characterize terrestrial mass exoplanets is the existence of time-variable features in the measured spectra, from both telluric absorption and stellar variability,...

Emotional predictors of returning a favour: Behavioural experiments in the United States and Japan

Abstract We examined emotional predictors of favour‐returning behaviour in the United States (Study 1) and tested whether the findings in the United States would replicate in a culturally different context in Japan (Study 2). In both experiments, participants played a collaborati...

Estimating temporal (2019–2025) and regional effects on Minnesotans' attitudes toward wolf hunting

Public attitudes toward wolf hunting are important for developing socially responsive wolf management policy. Drawing on two representative surveys of state residents, this study examined change in Minnesotans' (USA) support for wolf hunting in 2019 and 2025. We found that slight...

Generative AI in physics education: Approaches for instructors to integrate new tools with proven practices

Navigating generative artificial intelligence (GenAI) in higher education is a challenge for instructors, prompting calls for disciplinary guidance. This article connects current physics education research on GenAI with the Effective Practices for Physics Programs Guide, offering...

Shallow Landslides Align With Atmospheric Rivers in Coastal Steeplands

Abstract Rapid, shallow landslides in coastal mountains are triggered by extreme precipitation, shaping topography and impacting human settlements. Using an inventory of >700 landslides mapped from satellite imagery (2009–2024) and an atmospheric river database (1981–2019), this...

Peskine Sixfolds and Debarre–Voisin Fourfolds With Associated Cubic Fourfolds

ABSTRACT We develop the notion of Peskine sixfolds with associated K3 surfaces and cubic fourfolds and work out numerical conditions for when these associations occur. In discriminant 24, the first family for which there is an associated cubic fourfold, we identify the cubic expl...

Heatwaves and cold snaps alter host-parasite population dynamics

Climate change is increasing the frequency and intensity of temperature extremes, yet the consequences of heatwaves and cold snaps for host-parasite interactions remain incompletely understood.Thermal pulses of ±6°C were experimentally tested to determine how disease dynamics are...

ASector-Coupling Model to Evaluate the Role of Hydrogenin Low-Carbon Trucking

Abstract The global energy system must deeply decarbonize as soon as possible to avert the worst consequences of climate change, including the transportation sector, which accounts for 23% of global emissions. Several technological options have been proposed to decarbonize diesel...
