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 ...
Multi-Objective Reinforcement Learning for Designing Ethical Environments
AI research is being challenged with ensuring that autonomous agents learn to behave ethically, namely in alignment with moral values. A common approach, founded on the exploitation of Reinforcement Learning techniques, ...
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 ...
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 ...
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 $(f, g, h)$ ...
Delay Equations with Non-negativity Constraints Driven by a Hölder Continuous Function of Order $\beta \in\left(\frac{1}{3}, \frac{1}{2}\right)$
In this note we prove an existence and uniqueness result of solution for multidimensional delay differential equations with normal reflection and driven by a Hölder continuous function of order $\beta \in\left(\frac{1}{3}, ...
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 ...
Dynamic changes in microvascular flow conductivity and perfusion after myocardial infarction shown by image-based modeling
Background Microcirculation is a decisive factor in tissue reperfusion inadequacy following myocardial infarction (MI). Nonetheless, experimental assessment of blood flow in microcirculation remains a bottleneck. We sought ...
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 ...
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 ...
Mitigating annotation shift in cancer classification using single image generative models
Artificial Intelligence (AI) has emerged as a valuable tool for assisting radiologists in breast cancer detection and diagnosis. However, the success of AI applications in this domain is restricted by the quantity and ...
Chern degree functions
We introduce Chern degree functions for complexes of coherent sheaves on a polarized surface, which encode information given by stability conditions on the boundary of the $(\alpha, \beta)$-plane. We prove that these ...
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 ...
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 ...
When we talk about older people in HCI, who are we talking about? Towards a 'turn to community' in the design of technologies for a growing ageing population
This paper addresses a number of challenges HCI designers and researchers deal with when designing digital technologies for older people. We conducted a 5-year research-through-design study, which combined ethnography, ...
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 ...
Natural formations at the Earth Moon triangular point in perturbed restricted problems
Previous studies for small formation flying dynamics about triangular libration points have determined the existence of regions of zero and minimum relative radial acceleration with respect to the nominal trajectory, that ...
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 ...
