Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Previously undocumented regional variability in crab‐eating macaque skull sexual dimorphism and its implications for biological and morphometric studies

open access: yesThe Anatomical Record, EarlyView.
Abstract In a large sample of adult crab‐eating macaques, we quantified sexual dimorphism in size, shape, and covariance across the whole skull and among anatomical regions of the cranium and mandible. All regions showed significant mean sex differences, but the magnitude of size and shape dimorphism varied substantially.

Alliances, Nuclear Weapons and Escalation : Managing Deterrence in the 21st Century

open access: yes, 2021
In an era of great power competition, the role of alliances in managing escalation of conflict has acquired renewed importance. Nuclear weapons remain the ultimate means for deterrence and controlling escalation, and are central to US alliances in Europe

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Sheep Horn Development Revealed by Multi‐Tissue and Cross‐Species Transcriptomic Analysis

open access: yesAnimal Research and One Health, EarlyView.
Multi‐tissue and cross‐species transcriptomics with allele‐specific expression show sheep horns are a composite organ integrating epidermal and osteogenic programs. Conserved horn gene modules and cis‐regulatory variation fine‐tune expression networks underlying horn development and size (small scurs vs. large spiral horns).

Framing National Education in Hong Kong: A frame analysis of power dynamics in stakeholders' competing narratives

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This article examines how national education in Hong Kong functions as a contested arena in which state and non‐state actors struggle over the meaning of citizenship, identity and schooling. Using inductive frame analysis of 319 news articles (2020–2025) from five Chinese‐ and English‐language outlets, it identifies diagnostic, prognostic and ...
