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

The 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

The Origin And Loss Of Periodic Patterning In The Turtle Shell [PDF]

, 2014
The origin of the turtle shell over 200 million years ago greatly modified the amniote body plan, and the morphological plasticity of the shell has promoted the adaptive radiation of turtles. The shell, comprising a dorsal carapace and a ventral plastron,

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Transient Stability of Epigenetic Population Differentiation in a Clonal Invader

Frontiers in Plant Science, 2019
Epigenetic variation may play an important role in how plants cope with novel environments. While significant epigenetic differences among plants from contrasting habitats have often been observed in the field, the stability of these differences remains ...

Carrier‐free self‐assembled nanomedicine for combination‐therapy of acute myeloid leukemia

BMEMat, EarlyView.
CPDS combines drugs with three different mechanisms of action to achieve a multi‐mechanism combination therapy for AML by directly killing tumor cells and activating anti‐tumor immunity. Abstract As the main acute myeloid leukemia (AML) clinical treatment, the chemotherapy alone cannot meet the clinical therapeutic needs due to the high heterogeneity ...

Recent Progress on Fullerene–Based Functional Materials for Energy Conversion

Carbon Energy, EarlyView.
A schematic illustration summarizing the classification, and photo‐/electro‐‐/thermo‐catalysis and energy storage applications of C60 and derivatives. ABSTRACT Efficient energy conversion and environmental protection are still constrained by rapid carrier recombination, unstable interfaces, limited active site, and so on. Owing to the unique electronic
