In this paper, we present the analysis of incoherent non-thermal radio emission from a sample of hot magnetic stars, ranging from early-B to early-A spectral type. Spanning a wide range of stellar parameters and wind ...
Effects of an attachment-based intervention on autonomic regulation among opioid-exposed infants

Tabachnick, Alexandra R.; Eiden, Rina Das; Labella, Madelyn H.; Dozier, Mary (Developmental Psychobiology, 2022-06-02)

Little is known about whether postnatal intervention enhances autonomic regulation among infants at risk for dysregulation due to prenatal opioid exposure. The present study evaluated the effects of modified Attachment ...
Comparison of individual versus ensemble wind farm parameterizations inclusive of sub-grid wakes for the WRF model

Ma, Yulong; Archer, Cristina; Vasel-Be-Hagh, Ahmad (Wind Energy, 2022-06-02)

Wind turbine wakes can be predicted somewhat accurately with mesoscale numerical models, such as the Weather Research and Forecast (WRF) model, via a wind farm parameterization (WFP) that treats the effects of the wakes, ...
Winds of change: examining attitude shifts regarding an offshore wind project

Bingaman, Samantha; Firestone, Jeremy; Bidwell, David (Journal of Environmental Policy and Planning, 2022-06-01)

Understanding how local attitudes toward commercial-scale renewable energy change over time should provide insight into how to engage communities and influence public acceptance during the energy transition. To augment the ...
The Medical Diagnostics Major: Gateway to Medical School and Physician Assistant School

Hughes, Virginia C. (American Journal of Educational Research, 2022-05-25)

Medical diagnostics, offered at the University of Delaware College of Health Sciences, represents a novel major in higher education. This major incorporates courses similar to the preclinical content of professional schools ...
Reflections on the 2021 Decade Award: Navigating Paradox is Paradoxical

Lewis, Marianne W.; Smith, Wendy K. (Academy of Management Review, 2022-06-01)

We are delighted at the explosion of research advancing and applying paradox theory in the past 10 years and deeply honored to receive the 2021 Academy of Management Review Decade Award for the publication “Toward a Theory ...
The effect of early enrollment in dual-language immersion programs on children’s English reading development: findings from a 5-year longitudinal study

Shen, Ye; Wang, Rui; Zhang, Fan; Barbieri, Christina Areizaga; Pasquarella, Adrian (International Journal of Bilingual Education and Bilingualism, 2022-05-30)

The present study examined the effect of children’s enrollment in U.S. dual-language immersion (DLI) programs in first grade on English development across five years, using the Early Childhood Longitudinal Study, Kindergarten ...
Comparing steady and unsteady rectangular jets issuing into a crossflow

Tricouros, Frank A.; Amitay, Michael; Van Buren, Tyler (Journal of Fluid Mechanics, 2022-05-31)

The foundational differences of steady and unsteady jets issued into a laminar boundary layer crossflow are considered. Jets have been used widely for flow control applications, due to their ability to enhance mixing and ...
Solvation stabilizes intercarbonyl n→π* interactions and polyproline II helix

Zondlo, Neal J. (Physical Chemistry Chemical Physics, 2022-05-24)

n→π* interactions between consecutive carbonyls stabilize the α-helix and polyproline II helix (PPII) conformations in proteins. n→π* interactions have been suggested to provide significant conformational biases to the ...
Dynamic Steady State in Coastal Aquifers Is Driven by Multi-Scale Cyclical Processes, Controlled by Aquifer Storativity

Paldor, Anner; Frederiks, Ryan S.; Michael, Holly A. (Geophysical Research Letters, 2022-05-24)

Coastal aquifers supply freshwater to nearly half the global population, yet they are threatened by salinization. Salinities are typically estimated assuming steady-state, neglecting the effect of cyclical forcings on ...
