Riding Through Norms: Creating and Performing Athletic Femininity at American Ladies’ Equestrian Exhibitions, 1850–1890

open access: yesGender &History, EarlyView.
ABSTRACT During the nineteenth century, American agricultural fairs often featured ladies’ equestrian exhibitions. At these events, women constructed an athletic femininity based on skill and competitiveness that challenged traditional ideals of womanhood.

Effects of prematurity and socio‐economic status on early life language exposure: A video coding study

open access: yesBritish Journal of Developmental Psychology, EarlyView.
Abstract Preterm birth is associated with later language impairment and delay. Socio‐economic deprivation is linked to decreased language exposure in early childhood, but it is unknown how prematurity influences this relationship. This study investigated the effects of socio‐economic status and gestational age at birth on language exposure, in a sample

A new species of jewel‐babbler (Cinclosomatidae: Ptilorrhoa) from the Southern Fold Mountains of Papua New Guinea

open access: yesIbis, EarlyView.
Based on distinctive morphological and vocal characters we describe a new species of jewel‐babbler (genus Ptilorrhoa) from the forested karst of the Southern Fold Mountains in Papua New Guinea. The description is based on camera trap data and is presented in accordance with ICZN Declaration 45.

A Generation Mechanism of Banded Plasmaspheric Hiss

open access: yesGeophysical Research Letters
As a unique structure of plasmaspheric hiss emissions, banded hiss waves generally consist of an upper band above ∼200 Hz, a lower band below ∼100 Hz and a power gap in between. However, the generation mechanism of banded hiss remains unclear.

Modulation of Energetic Electron Precipitation Driven by Three Types of Whistler Mode Waves

open access: yesGeophysical Research Letters, 2023
Precipitation into the Earth's atmosphere due to pitch angle scattering by plasma waves has been recognized as one of the major loss mechanisms for energetic electrons.

Van Allen Probes Observations of Chorus Wave Vector Orientations: Implications for the Chorus‐to‐Hiss Mechanism

open access: yesGeophysical Research Letters, 2019
Using observations from the Van Allen Probes EMFISIS instrument, coupled with ray tracing simulations, we determine the fraction of chorus wave power with the conditions required to access the plasmasphere and evolve into plasmaspheric hiss.

The wide gape of snakes: A comparison of the developing mandibular symphysis in sauropsids

open access: yesJournal of Anatomy, EarlyView.
Our analysis explores the adaptations at the mandibular symphysis required to allow extreme lower jaw mobility in macrostomate snakes taking a comparative approach. Abstract The origin and evolution of snakes has been marked by the acquisition of many morphological and functional novelties, one of which is the possession of a highly kinetic skull ...

Plastid genome structure and phylogenomics of the freshwater red algal order Batrachospermales (Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract For the freshwater red algal order Batrachospermales, the number of plastid genomes available is relatively small compared to the number of genera. Fully assembled plastid genomes can provide insights into plastid evolution and crucial data for phylogenetic reconstruction.

Hisstology: High Spectral Spatial Resolution Magnetic Resonance Imaging Detection of Vasculature Validated by Histology and Micro–Computed Tomography

open access: yesMolecular Imaging, 2011
High spectral and spatial resolution (HiSS) data, acquired with echo-planar spectroscopic imaging (EPSI), can be used to acquire water spectra from each small image voxel.

An Efficient, Time‐Dependent High Speed Stream Model and Application to Solar Wind Forecasts

open access: yesSpace Weather, 2023
Predicting space weather effects of the solar wind requires knowing the location and properties of any embedded high speed streams (HSSs) or stream interactions regions (SIRs) that form as the fast solar wind catches up to slow preceding wind ...
