Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

American Journal of Agricultural Economics, EarlyView.Abstract This paper derives a firm‐level threshold, the Herfindahl Neutral Point, from the standard concentration index used in merger review. At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.

The Anatomical Record, EarlyView.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

A Gap Analysis of Deep Brain Stimulation for Childhood‐Onset Movement Disorders
Movement Disorders, EarlyView.Abstract Background Deep brain stimulation (DBS) is an established and increasingly utilized therapy for childhood‐onset movement disorders. However, pediatric DBS poses unique challenges that are not adequately addressed by adult‐derived paradigms. Objective To identify key gaps in the current use of DBS in childhood‐onset movement disorders and to ...

Using art history to explore society's changing connections with agriculture
PLANTS, PEOPLE, PLANET, EarlyView.Food insecurity is a looming challenge that especially affects those least fortunate. Consumer food choices have a substantial impact on the sustainability of current food systems. Here, we use art as a lens through which to consider our contemporary and historical relationship to one of the world's most crucial crops, the potato, in the context of the

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel
River Research and Applications, EarlyView.ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...
