Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

open access: yesThe Anatomical Record, EarlyView.
Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

Strip Casting of Sm2TM17-Type Alloys for Production of the Metastable SmTM7 Phase

open access: yesMetals
Conventional book casting of Sm2TM17-type alloys (where TM = Co, Fe, Cu, Zr) leads to a coarse, highly segregated microstructure, predominantly due to the slow, variable cooling rate from the mould surface towards the centre of the ingot.

Crossing Minimization for 1-page and 2-page Drawings of Graphs with Bounded Treewidth

open access: yes, 2014
We investigate crossing minimization for 1-page and 2-page book drawings. We show that computing the 1-page crossing number is fixed-parameter tractable with respect to the number of crossings, that testing 2-page planarity is fixed-parameter tractable ...

Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

open access: yesThe Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Medieval Dobrun [PDF]

open access: yesStarinar, 2002
An interesting and highly structured medieval complex, Dobrun has been attracting attention of scholars for a long time. Unlike the ruins of medieval fortifications, the remains of wall-painting in the former monastery church received most of the ...

Four Pages Are Indeed Necessary for Planar Graphs [PDF]

open access: yes, 2020
An embedding of a graph in a book consists of a linear order of its vertices along the spine of the book and of an assignment of its edges to the pages of the book, so that no two edges on the same page cross. The book thickness of a graph is the minimum

A Comparative Study of the ReCell® Device and Autologous Split-Thickness Meshed Skin Graft in the Treatment of Acute Burn Injuries

open access: yesJournal of Burn Care & Research, 2018
Early excision and autografting are standard care for deeper burns. However, donor sites are a source of significant morbidity. To address this, the ReCell® Autologous Cell Harvesting Device (ReCell) was designed for use at the point-of-care to prepare a

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.

Defective and Clustered Choosability of Sparse Graphs

open access: yes, 2019
An (improper) graph colouring has "defect" $d$ if each monochromatic subgraph has maximum degree at most $d$, and has "clustering" $c$ if each monochromatic component has at most $c$ vertices.
