La Neutro-Geometría y la Anti-Geometría como Alternativas y Generalizaciones de las Geometrías no Euclidianas [PDF]
, 2022 In this paper we extend Neutro-Algebra and Anti-Algebra to geometric spaces, founding Neutro/Geometry and AntiGeometry. While Non-Euclidean Geometries resulted from the total negation of a specific axiom (Euclid's Fifth Postulate), AntiGeometry results ...

Phylogenetic Forest Spaces [PDF]
, 2022 Given a fixed set of operational taxonomic units (OTUs), when studying their evolutionary relationships among each other, a common way of depicting those is to construct a phylogenetic tree, a graph-theoretic tree with a root, that is the common ancestor

Pentagram maps over rings, Grassmannians, and skewers [PDF]
The pentagram map is a discrete dynamical system on planar polygons. By definition, the image of a polygon $P$ under the pentagram map is the polygon $P'$ whose vertices are the intersection points of consecutive shortest diagonals of $P$.

Extremale spektrale Dynamik und eine Fraktaltheorie für Simplizialkomplexe
, 2023 The aim of this work is the exploration of spectral asymptotics of certain geometries associated to simplicial complexes. We will state how combinatorial and differential Laplacians can be associated to a simplicial complex and describe certain ...

Gravité quantique comme théorie des champs de géométries discrètes
, 2022 The Plebanski formulation of general relativity indeed shows that four dimensional gravity can be studied as a constrained topological model. This led the focus of part of the quantum gravity community towards topological (quantum) field theories.

Riemannian and stratified geometries on covariance and correlation matrices
, 2022 Dans de nombreuses applications, les données sont des matrices de covariance ou de corrélation entre plusieurs signaux (EEG, MEG, fMRI), grandeurs physiques (cellules, gènes) ou instants (autocorrélation).

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced Engineering Materials, EarlyView.Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Multimodal Data‐Driven Microstructure Characterization
Advanced Engineering Materials, EarlyView.A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.
