Assessment of Stroke by Analysing Cartoid Plaque Morphology [PDF]
, 2009 Stroke is the third leading cause of death in the Western world and a major cause of disability in adults. The objective of this work was to investigate morphological feature extraction techniques and the use of automatic classifiers; in order to develop a computer aided system that will facilitate the automated characterization of carotid plaques for ...

Geometric computation theory for morphological filtering on freeform surfaces [PDF]
, 2013 Surfaces govern functional behaviours of geometrical products, especially high precision and high added-value products. Compared to the mean-line based filters, morphological filters, evolved from the traditional E-system, are relevant to functional ...

Morphological and Phylogenetic Analyses Reveal Five New Species in Chaetosphaeriaceae
Journal of Fungi, 2022 Chaetosphaeriaceae is a genera-rich and highly diverse group of fungi with a worldwide distribution in terrestrial and aquatic habitats. Eight fresh collections of Chaetosphaeriaceae were obtained during investigations of hyaline-spored hyphomycetes in ...

Quantitative analyses of squamate dentition demonstrate novel morphological patterns.
PLoS ONE, 2021 Squamates are ideal subjects for investigating relationships between diet and dental patterns because they exhibit wide dietary diversity, marked variation in dental shape, and are taxonomically abundant. Despite this, well-established links between diet

Fossils improve phylogenetic analyses of morphological characters [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2020 Abstract Fossils provide our only direct window into evolutionary events in the distant past. Incorporating them into phylogenetic hypotheses of living clades can help elucidate macroevolutionary patterns and processes, such as ancestral states and diversification dynamics. However, the effect fossils have on phylogenetic inference from

Additions to Lyophyllaceae s.l. from China
Journal of Fungi, 2021 Four new species, viz. Calocybe coacta, C. fulvipes, C. vinacea and Clitolyophyllum umbilicatum, are described in northern China. Comparisons are made of macro- and micromorphological features among the new species and closely related species within the ...
