Morphological-based Analyses for Parameterizing Symmetry in Radio Galaxies

open access: yesThe Astronomical Journal, 2023
The morphology of radio galaxies can provide significant clues to describe the formation and evolution of galaxies in the Universe. Here, we aim to extract the morphological parameters of radio galaxies and define symmetry criteria as some of the ...

Principle and geomorphological applicability of summit level and base level technique using Aster Gdem satellite-derived data and the original software Baz

open access: yesActa Scientiarum: Technology, 2015
This article presents principle and geomorphological applicability of summit level technique using Aster Gdem satellite-derived topographicdata. Summit level corresponds to thevirtualtopographic surface constituted bylocalhighest points, such as peaks ...

Morphological and Phylogenetic Analyses Reveal Five New Species in Chaetosphaeriaceae

open access: yesJournal 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.

open access: yesPLoS 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

Analysing the Visual Dynamics of Spatial Morphology [PDF]

open access: yesEnvironment and Planning B: Planning and Design, 2003
Recently there has been a revival of interest in visibility analysis of architectural configurations. The new analyses rely heavily on computing power and statistical analysis, two factors which, according to the postpositivist school of geography, should immediately cause us to be wary.

Assessment of Stroke by Analysing Cartoid Plaque Morphology [PDF]

open access: yes, 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 ...

Disentangling the Taxonomic History of the Widespread and Overlooked Centric Diatom Stephanodiscus makarovae and Its Transfer to Cyclostephanos

open access: yesTaxonomy, 2021
Stephanodiscus makarovae, a taxon originally described from Russia, is morphologically similar to several other taxa within Cyclostephanos, namely C. invisitatus, C. delicatus and C. tholiformis.

Combining stable isotopes, morphological, and molecular analyses to reconstruct the diet of free‐ranging consumers

open access: yesEcology and Evolution, 2020
Accurate estimates of animal diet composition are essential to untangle complex interactions in food webs. Biomarkers and molecular tools are increasingly used to estimate diet, sometimes alongside traditional dietary tracing methods.

Additions to Lyophyllaceae s.l. from China

open access: yesJournal 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 ...

Fossils improve phylogenetic analyses of morphological characters [PDF]

open access: yesProceedings 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
