Special values of triple-product -adic L-functions and non-crystalline diagonal classes
The main purpose of this note is to understand the arithmetic encoded in the special value of the $p$-adic $L$-function $E_p^g$ (f, $\left.\mathbf{g}, \mathbf{h}\right)$ associated to a triple of modular forms $(f, g, h)$ ...
Generic Feature Learning for Wireless Capsule Endoscopy Analysis
The interpretation and analysis of wireless capsule endoscopy (WCE) recordings is a complex task which requires sophisticated computer aided decision (CAD) systems to help physicians with video screening and, finally, with ...
El polinomio de Poincaré-Hodge de un producto simétrico de variedades Kählerianas compactas
In this paper we compute the Poincaré-Hodge polynomial of a symmetric product of a compact kähler manifold, following the method used by Macdonald, in the topological case, to compute, the Poincaré polynomial of a compact ...
L'assignació de metadades a llibres digitals en el format EPUB3. Primera part. Les metadades en les especificacions de l'EPUB3
Objectius: descriure els mecanismes i la funció de les metadades internes i descriptives en el format EPUB3 segons els estàndards vigents i les bones pràctiques difoses per la indústria editorial, i identificar un conjunt ...
Multi-Centre, Multi-Vendor and Multi-Disease Cardiac Segmentation: The M&Ms Challenge
The emergence of deep learning has considerably advanced the state-of-the-art in cardiac magnetic resonance (CMR) segmentation. Many techniques have been proposed over the last few years, bringing the accuracy of automated ...
Expansion of the density: a Wiener-chaos approach
We prove a Taylor expansion of the density pε(y) of a Wiener functional Fε with Wiener-chaos decomposition Fε=y+∑∞n=1εnIn(fn), ε∈(0,1]. Using Malliavin calculus, a precise description of the coefficients in the development ...
Graded algebra automorphisms
We consider the Clifford algebra C(q) of a regular quadratic space (V, q) over a field K with its structure of Z/2Z-graded K-algebra. We give a characterization of the group of graded automorphisms of C(q). In the last ...
A Conceptual Probabilistic Framework for Annotation Aggregation of Citizen Science Data
Over the last decade, hundreds of thousands of volunteers have contributed to science by collecting or analyzing data. This public participation in science, also known as citizen science, has contributed to significant ...
Organ Segmentation in Poultry Viscera Using RGB-D
We present a pattern recognition framework for semantic segmentation of visual structures, that is, multi-class labelling at pixel level, and apply it to the task of segmenting organs in the eviscerated viscera from ...
Modular abelian varieties over number fields
The main result of this paper is a characterization of the abelian varieties $B / K$ defined over Galois number fields with the property that the $L$-function $L(B / K ; s)$ is a product of $L$-functions of non-CM newforms ...
Sumsets and Veronese varieties
In this paper, to any subset $\mathcal{A} \subset \mathbb{Z}^n$ we explicitly associate a unique monomial projection $Y_{n, d_{\mathcal{A}}}$ of a Veronese variety, whose Hilbert function coincides with the cardinality of ...
The differentiable chain functor is not homotopy equivalent to the continuous chain functor
Let $S_*$ and $S_*^\{infty}$ be the functors of continuous and differentiable singular chains on the category of differentiable manifolds. We prove that the natural transformation $i: S_*^\infty \rightarrow S_*$, which ...
Reversible perturbations of conservative Henon-like maps
For area-preserving Hénon-like maps and their compositions, we consider smooth perturbations that keep the reversibility of the initial maps but destroy their conservativity. For constructing such perturbations, we use two ...
On the structure of the canonical module of the Rees algebra and the associated graded ring of and ideal
In this note we give the description of a morphism related with the structure of the canonocal module of the Rees algebra R(I) of an ideal I in a local ring . As an application we obtain Ikeda's criteria for the Gorensteinness ...
On the Galois correspondence theorem in separable Hopf Galois theory
In this paper we present a reformulation of the Galois correspondence theorem of Hopf Galois theory in terms of groups carrying farther the description of Greither and Pareigis. We prove that the class of Hopf Galois ...
The Calderón problem for nonlocal Schrödinger equations with homogeneous, directionally antilocal principal symbols
In this article we consider direct and inverse problems for $\alpha$-stable, elliptic nonlocal operators whose kernels are possibly only supported on cones and which satisfy the structural condition of directional antilocality ...
Chaotic Kabanov formula for the Azéma martingales
We derive the chaotic expansion of the product of nth- and first-order multiple stochastic integrals with respect to certain normal martingales. This is done by application of the classical and quantum product formulae for ...
Rational cohomology tori
We study normal compact varieties in Fujiki's class $\mathcal{C}$ whose rational cohomology ring is isomorphic to that of a complex torus. We call them rational cohomology tori. We classify, up to dimension three, those ...
Linear statistics of determinantal point processes and norm representations
We study the asymptotic behavior of the fluctuations of smooth and rough linear statistics for determinantal point processes on the sphere and on the Euclidean space. The main tool is the generalization of some norm ...
Topología grassmanniana sobre los ideales cerrados de codimensión finita en un álgebra de Banach conmutativa.
El objeto de esta nota es el de dar una construcción natural de una topología para el conjunto de los ideales cerrados de codimensión n de un álgebra de Banach conmutativa, dando una condición necesaria y suficiente ...
