Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

GAUFRE: A tool for an automated determination of atmospheric parameters from spectroscopy

EPJ Web of Conferences, 2013
We present an automated tool for measuring atmospheric parameters (Teff, log g), [Fe/H]) for F-G-K dwarf and giant stars. The tool, called GAUFRE, is composed of several routines written in C++: GAUFRE-RV measures radial velocity from spectra via cross ...

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

The 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.

Simulated Effects of Radioactive Elements on Magnetic Evolution and Atmospheric Mass Loss of Earth-like Planets

The Astrophysical Journal
Thousands of exoplanets have been discovered in recent decades, yet Earth remains the only known world with life. To assess the potential habitability of other planets, we must identify the importance of various physical conditions that may contribute to

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

The 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 ...

Low-amplitude Solar-like Oscillations in the K5 V Star ϵ Indi A

The Astrophysical Journal
We have detected solar-like oscillations in the mid-K-dwarf ϵ Indi A, making it the coolest dwarf to have measured oscillations. The star is noteworthy for harboring a pair of brown dwarf companions and a Jupiter-type planet.

M dwarf stars in the light of (future) exoplanet searches

, 2013
We present a brief overview of a splinter session on M dwarf stars as planet hosts that was organized as part of the Cool Stars 17 conference. The session was devoted to reviewing our current knowledge of M dwarf stars and exoplanets in order to prepare ...

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

The 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,
