An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation
The Anatomical Record, EarlyView.Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

Journal of the Association for Information Science and Technology, EarlyView.Abstract This paper reports on findings from 15 semi‐structured interviews with LGBTQIA+ individuals within the United States who have experienced the loss of one or more LGBTQIA+ information spaces. The paper specifically focuses on how such losses occurred and the information transitions experienced by the participants in response to this loss ...

Classical, quantum and numerical aspects of modified theories of gravity
This thesis considers modifications of some specific and well-known gravity theories. In particular, linearised infinite-derivative gravity theories are studied in both four-dimensional and two-dimensional space-time. For the four-dimensional case, some specific quantum aspects of infinite-derivative gravity are examined.

Astronomische Nachrichten, EarlyView.ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

‘Let's talk about the weather’: The activist curriculum and global climate change education
British Educational Research Journal, EarlyView.Abstract Activist movements have garnered significant global attention on a range of sustainability issues, often involving collectives of citizens coming together. Invoked is the idea of citizens informed to act, emerging not from a common‐sense understanding of everyday life, but rather from a deep political understanding of the world—one that is ...

Existence of vacuum wormholes in Einsteinian cubic gravity
Journal of High Energy PhysicsWormhole solutions in gravitational theories typically require exotic matter. Here we present a wormhole solution to the field equations of Einsteinian Cubic Gravity — a phenomenological competitor to general relativity that includes terms cubic in the ...

British Educational Research Journal, EarlyView.Abstract This article examines how UK and US universities manage racial equality regimes through governance structures that prioritise institutional reputation over substantive racial justice reform. Drawing on Bourdieu's field, habitus and capital theory, the study demonstrates how universities neutralise racial justice efforts through bureaucratic ...
