Cerámica, iconografía y estructuras simétricas

Relaciones de la Sociedad Argentina de Antropología, 2023
El concepto de estilo ha sido ampliamente utilizado en la arqueología, sin embargo, sus usos no han incluido la idea de analizar los diseños geométricos según una nomenclatura matemáticamente estandarizada.

3D pollination biology using micro‐computed tomography and geometric morphometrics in Theobroma cacao

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

Skeletal age during hurricane impacts fluctuating asymmetry in Cayo Santiago rhesus macaques

Ecology and Evolution, Volume 13, Issue 8, August 2023., 2023
Fluctuating asymmetry (FA), or random deviations from symmetry, can be used as a proxy for developmental instability, and anthropogenic and natural disruptions have been associated with increased levels of FA. In this study, we investigate the effect of demographic variables (age, sex, and decade of birth) and hurricane experience on FA in a model ...

Noncompartmental pharmacokinetics of three intravenous mycophenolate mofetil concentrations in healthy Standardbred mares

Veterinary Dermatology, Volume 34, Issue 3, Page 222-234, June 2023., 2023
Background – Mycophenolate mofetil (MMF) is the prodrug of mycophenolic acid (MPA) which acts as an immunosuppressive agent. During the biotransformation of MMF to MPA, additional metabolites including MPA phenol glucuronide (MPAG), MPA acyl glucuronide (AcMPAG) and MPA phenol glucoside (MPG) are formed.

A comparative study on deep‐learning methods for dense image matching of multi‐angle and multi‐date remote sensing stereo‐images

The Photogrammetric Record, Volume 37, Issue 180, Page 385-409, December 2022., 2022
Among all stereo matching methods End‐to‐End (E2E) learning methods show that they can achieve the lowest and most frequent minimum errors, however, their performance drastically changes across different test‐sites, which indicates poor generalisation capabilities.

Cranial ecomorphology of turtles and neck retraction as a possible trigger of ecological diversification

Evolution, Volume 76, Issue 11, Page 2566-2586, November 2022., 2022
Abstract Turtles have a highly modified body plan, including a rigid shell that constrains postcranial anatomy. Skull morphology and neck mobility may therefore be key to ecological specialization in turtles. However, the ecological signal of turtle skull morphologies has not been rigorously evaluated, leaving uncertainties about the roles of ...
