New perspectives on body size and shape evolution in dinosaurs

open access: yesBiological Reviews, EarlyView.
ABSTRACT Diversity in the body shapes and sizes of dinosaurs was foundational to their widespread success during the Mesozoic era. The ability to quantify body size and form reliably is therefore critical to the study of dinosaur biology and evolution.

From the atmosphere to the circumstellar environment in cool evolved stars

open access: yes, 2014
We discuss and illustrate contributions that optical interferometry has made on our current understanding of cool evolved stars. We include red giant branch (RGB) stars, asymptotic giant branch (AGB) stars, and red supergiants (RSGs).

Correlation of Structure With Function: Future Utilities for Optical Coherence Tomography Angiography in Neuro‐Ophthalmology

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Optical coherence tomography angiography is a burgeoning imaging modality in Ophthalmology. In this review, we outline the breadth of potential utility for optical coherence tomography angiography for diagnosis and prognostication in neuro‐ophthalmology.

Downlisting and recovery of species assessed by the IUCN

open access: yesConservation Biology, EarlyView.
Abstract Despite the increasing number of species assessed for extinction risk by the International Union for Conservation of Nature (IUCN) (163,040 species as of 2024), only about 1 in 1,000 have been downlisted due to genuine population improvement. Although this rare conservation achievement has been widely celebrated in several recent cases, some ...

PSR J1947−1120: A New Huntsman Millisecond Pulsar Binary

open access: yesThe Astrophysical Journal
We present the discovery of PSR J1947–1120, a new huntsman millisecond pulsar with a red giant companion star in a 10.3 day orbit. This pulsar was found via optical, X-ray, and radio follow-up of the previously unassociated γ -ray source 4FGL J1947.6 ...

Testing the cores of first ascent red-giant stars using the period spacing of g modes

open access: yes, 2015
In the context of the determination of stellar properties using asteroseismology, we study the influence of rotation and convective-core overshooting on the properties of red-giant stars.

A Bibliometric Analysis of Four Decades of Shareholder Activism Research

open access: yesCorporate Governance: An International Review, EarlyView.
ABSTRACT Research Questions/Issue In this bibliometric review of shareholder activism literature spanning 1983–2021, we pursue two objectives. Firstly, we investigate the degree of interdisciplinarity in the field, and second, we scrutinize publication trends, foundational knowledge, core topics, and emerging thematic trends, exploring the trajectory ...

Maternal Nutritional Status Governs Fetal Development by Modulating Imprinting Gene GAB1‐Mediated Trophoblast Differentiation in the Placenta

open access: yesCell Proliferation, EarlyView.
Maternal nutrient restriction disrupts placental homeostasis via GAB1 dysregulation—involving both transcriptional downregulation and autophagy‐dependent protein degradation. These molecular alterations inhibit MAPK signalling‐mediated trophoblast fusion, leading to structural and functional deficits in the maternal–fetal exchange interface.
