Weighted persistence intensity regression
Matteo Pegoraro, Mario Beraha
Persistence diagrams summarize the multiscale topological structure of data, and in applications they often arrive paired with covariates. We develop nonparametric methodology and…
Building confidence regions for Reeb graphs using the interleaving distance
Matteo Pegoraro, Alberto Conforti, Mathieu Carrière
We develop confidence regions for Reeb graphs from finite samples using the interleaving distance. Given a point cloud equipped with a filter function, we construct a finite proxim…
Persistence Spheres: a Bi-continuous Linear Representation of Measures for Partial Optimal Transport
Matteo Pegoraro
We improve and extend persistence spheres, introduced in~\cite{pegoraro2025persistence}. Persistence spheres map an integrable measure on the upper half-plane, including persis…
Persistence Spheres: Bi-continuous Representations of Persistence Diagrams
Matteo Pegoraro
We introduce persistence spheres, a novel functional representation of persistence diagrams. Unlike existing embeddings (such as persistence images, landscapes, or kernel methods),…
Persistence diagrams for exploring the shape variability of abdominal aortic aneurysms
Dario Arnaldo Domanin, Matteo Pegoraro, Santi Trimarchi +2
Abdominal Aortic Aneurysm consists of a permanent dilation in the abodminal portion of the aorta and, along with its associated pathologies like calcifications and intraluminal thr…
Circular Max-Flow for Periodic Data via Reeb Graphs
Matteo Pegoraro, Lisbeth Fajstrup
We introduce a max-flow framework for data with periodic boundary conditions, motivated by the analysis of transport in atomistic materials. Starting from a space X equipped with a…
Wasserstein Principal Component Analysis for Circular Measures
Mario Beraha, Matteo Pegoraro
We consider the 2-Wasserstein space of probability measures supported on the unit-circle, and propose a framework for Principal Component Analysis (PCA) for data living in such a s…
A Persistence-Driven Edit Distance for Trees with Abstract Weights
Matteo Pegoraro
In this work we define a novel edit distance for trees considered with some abstract weights on the edges. The metric is driven by the idea of considering trees as topological summ…
Virgo Detector Characterization and Data Quality: tools
F. Acernese, M. Agathos, A. Ain +491
Detector characterization and data quality studies -- collectively referred to as {\em DetChar} activities in this article -- are paramount to the scientific exploitation of the jo…
Virgo Detector Characterization and Data Quality: results from the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave (GW) signals in the past few years, alongside the two Adv…
Imaging-based representation and stratification of intra-tumor Heterogeneity via tree-edit distance
Lara Cavinato, Matteo Pegoraro, Alessandra Ragni +3
Personalized medicine is the future of medical practice. In oncology, tumor heterogeneity assessment represents a pivotal step for effective treatment planning and prognosis predic…
Virgo Detector Characterization and Data Quality during the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave signals in the past few years, alongside the two LIGO ins…
The Virgo O3 run and the impact of the environment
F. Acernese, M. Agathos, A. Ain +486
Sources of geophysical noise (such as wind, sea waves and earthquakes) or of anthropogenic noise impact ground-based gravitational-wave interferometric detectors, causing transient…
A Graph-Matching Formulation of the Interleaving Distance between Merge Trees
Matteo Pegoraro
In this work we study the interleaving distance between merge trees from a combinatorial point of view. We use a particular type of matching between trees to obtain a novel formula…
A Finitely Stable Edit Distance for Merge Trees
Matteo Pegoraro
In this paper we define a novel edit distance for merge trees, which we argue to be suitable for a good range of applications. Relying also on some technical results contained in o…
Functional Data Representation with Merge Trees
Matteo Pegoraro, Piercesare Secchi
In this paper we face the problem of representation of functional data with the tools of algebraic topology. We represent functions by means of merge trees, which, like the more co…
A Finitely Stable Edit Distance for Functions Defined on Merge Trees
Matteo Pegoraro
In this work we define a metric structure to compare functions defined on different merge trees. The metric introduced possesses some stability properties, which we illustrate with…
Projected Statistical Methods for Distributional Data on the Real Line with the Wasserstein Metric
Matteo Pegoraro, Mario Beraha
We present a novel class of projected methods, to perform statistical analysis on a data set of probability distributions on the real line, with the 2-Wasserstein metric. We focus…
Spatially dependent mixture models via the Logistic Multivariate CAR prior
Mario Beraha, Matteo Pegoraro, Riccardo Peli +1
We consider the problem of spatially dependent areal data, where for each area independent observations are available, and propose to model the density of each area through a finit…
Study of the effects of radiation on the CMS Drift Tubes Muon Detector for the HL-LHC
G. Abbiendi, J. Alcaraz Maestre, A. Álvarez Fernández +140
The CMS drift tubes (DT) muon detector, built for withstanding the LHC expected integrated and instantaneous luminosities, will be used also in the High Luminosity LHC (HL-LHC) at…
Noise reduction in muon tomography for detecting high density objects
M. Benettoni, G. Bettella, G. Bonomi +18
The muon tomography technique, based on multiple Coulomb scattering of cosmic ray muons, has been proposed as a tool to detect the presence of high density objects inside closed vo…
Effects of breaking vibrational energy equipartition on measurements of temperature in macroscopic oscillators subject to heat flux
Livia Conti, Paolo De Gregorio, Gagik Karapetyan +4
When the energy content of a resonant mode of a crystalline solid in thermodynamic equilibrium is directly measured, assuming that quantum effects can be neglected it coincides wit…
