A Survey of Model Fits to Brown Dwarf Spectra Through the L–T Sequence

open access: yesThe Astronomical Journal
We fit archival near-IR spectra of ∼300 brown dwarfs with atmosphere models from the Sonora and Phoenix groups. Using the parameters of the best-fit models as estimates for the physical properties of the brown dwarfs in our sample, we have performed a ...

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

open access: yesThe Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

The Sonora Substellar Atmosphere Models. VI. Red Diamondback: Extending Diamondback with SPHINX for Brown Dwarf Early Evolution

open access: yesThe Astrophysical Journal
We extend the Sonora Diamondback brown dwarf evolution models to higher effective temperatures to treat the evolution of younger, higher-mass objects. Due to an upper temperature limit of T _eff  =  2400 K in the original Sonora Diamondback model grid ...

Clouds and chemistry across the brown dwarf T-Y sequence: Insights from JWST atmospheric retrievals

open access: yesAstronomy & Astrophysics
The James Webb Space Telescope offers exceptional spectral resolution and wavelength coverage, which are essential for studying the coldest brown dwarfs, particularly Y dwarfs.

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

open access: yesThe Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

open access: yesThe Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Di scovery of a T dwarf + white dwarf binary system

open access: yes, 2011
We present the discovery of the first T dwarf + white dwarf binary system LSPM 1459+0857AB, confirmed through common proper motion and spectroscopy. The white dwarf is a high proper motion object from the LSPM catalogue that we confirm spectroscopically ...

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

open access: yesThe Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.
