The training of soccer assistant referees beyond on-field experience: the use of the Interactive Video Test

International Journal of Computer Science in Sport, 2018
The main objective of this article was to analyse whether the Interactive Video Test (IVT) is a useful tool for the practical off-field training of soccer assistant referees, and if its use could reduce erroneous on-field decisions when applying Law 11 ...

Geometric properties of the family of p-parallel bodies

Analysis and Geometry in Metric Spaces
We study geometric properties of the family of p-parallel bodies of a convex body K with respect to a gauge body E. In particular, we investigate various regularity properties of their boundaries by means of their 0-extreme vectors, aiming for extensions

Conservation for Teaching: Restoration and Educational Use of an 18th-Century “Albarelo” at the Museum of the History of Pharmacy in Seville (Spain)

Heritage
The permanent historical-pharmaceutical collection at the Faculty of Pharmacy, University of Seville (Spain), offers visitors a vivid impression of what an apothecary’s shop looked like around the turn of the 19th to the 20th century.

On Penrose’s Analogy between Curved Spacetime Regions and Optical Lenses

Philosophy of Physics
We present a detailed analysis of Penrose’s gravito-optical analogy between the focusing effects of particular families of Ricci- and Weyl-curved spacetime regions on the one hand, and anastigmatic and astigmatic optical lenses on the other.

On the geometry of topological defects in glasses

Nature Communications
Abstract Recent studies have revealed a series of connections between the topological features of structural glasses and their material properties. These findings bear a striking resemblance to results observed in quantum physics, underscoring the significance of the nature of the wavefunction.

Singularities in Geometry and Topology

, 2018
This thesis consists of two different topics that are not related. The thesis has two different and independent parts that can be read in any order. The purpose of this work is to study two topics in singularity theory: 1. The McKay correspondence for Gorenstein surface singularities. 2.
