Bayesian Regression Analysis for Dependent Data with an Elliptical Shape

open access: yesEntropy
This paper proposes a parametric hierarchical model for functional data with an elliptical shape, using a Gaussian process prior to capturing the data dependencies that reflect systematic errors while modeling the underlying curved shape through a von ...

On the Images of Ellipses Under Similarities

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013
We consider ellipses corresponding to any norm function on the complex plane and determine their images under the similarities which are special Möbius transformations.

Cardiovagal Baroreflex Hysteresis Using Ellipses in Response to Postural Changes

open access: yesFrontiers in Neuroscience, 2021
The cardiovagal branch of the baroreflex is of high clinical relevance when detecting disturbances of the autonomic nervous system. The hysteresis of the baroreflex is assessed using provoked and spontaneous changes in blood pressure.

Cell Shape and Surface Colonisation in the Diatom Genus Cocconeis—An Opportunity to Explore Bio-Inspired Shape Packing?

open access: yesBiomimetics, 2019
Optimal packing of 2 and 3-D shapes in confined spaces has long been of practical and theoretical interest, particularly as it has been discovered that rotatable ellipses (or ellipsoids in the 3-D case) can, for example, have higher packing densities ...

An Improved Method for Estimating Renal Dimensions; Implications for Management of Kidney Disease

open access: yesApplied Sciences, 2019
Changes in renal dimensions, including total kidney volume, not only inform ongoing renal disease but also disease progression. Determination of renal dimensions can inform drug efficacy, is important for matching recipients with potential donors, and to
