A Fair and Scalable Mechanism for Resource Allocation: The Multilevel QPQ Approach
Doncel Vicente, Josu
; De la Pisa Arribas, Luis; Santos, Agustín; Fernández Anta, Antonio (IEEE, 2020-12-29)
In this paper the problem of distributing resources among a collection of users (or players) is explored. These players have independent preferences to get these resources and can be dishonest about their preferences in ... -
Age of Information in a Decentralized Network of Parallel Queues with Routing and Packets Losses
Doncel Vicente, Josu; (Korean Institute of Communications and Information Sciences, 2022-02)
The paper deals with age of information (AoI) in a network of multiple sources and parallel queues with buffering capabilities, preemption in service and losses in served packets. The queues do not communicate between each ... -
Age of Information of a Server with Energy Requirements
Doncel Vicente, Josu (PeerJ, 2021-03-01)
We investigate a system with Poisson arrivals to two queues. One queue stores the status updates of the process of interest (or data packets) and the other handles the energy that is required to deliver the updates to the ... -
An Uncertainty Principle for Solutions of the Schrödinger Equation on H-Type Groups
Fernández Bertolin, Aingeru; ; (Cambridge University Press, 2020-04-02)
In this paper we consider uncertainty principles for solutions of certain partial differential equations on H -type groups. We first prove that, on H -type groups, the heat kernel is an average of Gaussians in the central ... -
Analysis of an optimal policy in dynamic bipartite matching models
Cadas, Arnaud; Doncel Vicente, Josu; Bušić, Ana (Elsevier, 2022-04)
[EN] A dynamic bipartite matching model is given by a bipartite matching graph which determines the possible matchings between the various types of supply and demand items. Both supply and demand items arrive to the system ... -
Autofluorescence Image Reconstruction and Virtual Staining for In-Vivo Optical Biopsying
Picón Ruiz, Artzai; Medela Ayarzaguena, Alfonso; Sánchez Peralta, Luisa F.; Cicchi, Riccardo; Bilbao, Roberto; Alfieri, Domenico; ; Glover, Ben; López Saratxaga, Cristina (IEEE-Institute of Electrical and Electronics Engineers, 2021-02-22)
Modern photonic technologies are emerging, allowing the acquisition of in-vivo endoscopic tissue imaging at a microscopic scale, with characteristics comparable to traditional histological slides, and with a label-free ... -
Bearing Assessment Tool for Longitudinal Bridge Performance
; Fernández Navamuel del Olmo, Ana; ; ; Pardo Zubiaur, David (Springer, 2020-11)
This work provides an unsupervised learning approach based on a single-valued performance indicator to monitor the global behavior of critical components in a viaduct, such as bearings. We propose an outlier detection ... -
Convexity properties of discrete Schrödinger evolutions
Fernández Bertolin, Aingeru (Springer Nature, 2019-07-01)
In this paper, we give log-convexity properties for solutions to discrete Schrödinger equations with different discrete versions of Gaussian decay at two different times. For free evolutions, we use complex analysis arguments ... -
Dynamical versions of Hardy's uncertainty principle: A survey
Fernández Bertolin, Aingeru; Malinnikova, Eugenia (American Mathematical Society, 2021-06-03)
The Hardy uncertainty principle says that no function is better localized together with its Fourier transform than the Gaussian. The textbook proof of the result, as well as one of the original proofs by Hardy, refers to ... -
From Heisenberg uniqueness pairs to properties of the Helmholtz and Laplace equations
Fernández Bertolin, Aingeru; Gröchenig, Karlheinz; Jaming, Philippe (Elsevier, 2018-09-07)
The aim of this paper is to establish uniqueness properties of solutions of the Helmholtz and Laplace equations. In particular, we show that if two solutions of such equations on a domain of Rd agree on two intersecting d ... -
Hardy's uncertainty principle and unique continuation property for stochastic heat equations
Fernández Bertolin, Aingeru; Zhong, Jie (EDP Sciences, 2020-02-14)
The goal of this paper is to prove a qualitative unique continuation property at two points in time for a stochastic heat equation with a randomly perturbed potential, which can be considered as a variant of Hardy’s ... -
Insights into the dynamic trajectories of protein filament division revealed by numerical investigation into the mathematical model of pure fragmentation
; Escobedo Martínez, Miguel; ; (Public Library Of Science, 2021-09-03)
The dynamics by which polymeric protein filaments divide in the presence of negligible growth, for example due to the depletion of free monomeric precursors, can be described by the universal mathematical equations of 'pure ... -
Size-Based Routing Policies: Non-Asymptotic Analysis and Design of Decentralized Systems
Bachmat, Eitan; Doncel Vicente, Josu (MDPI, 2021-04-12)
Size-based routing policies are known to perform well when the variance of the distribution of the job size is very high. We consider two size-based policies in this paper: Task Assignment with Guessing Size (TAGS) and ... -
Supervised Deep Learning with Finite Element simulations for damage identification in bridges
Fernández Navamuel del Olmo, Ana; ; ; Pardo Zubiaur, David ; ; (Elsevier, 2022-04-15)
[EN] This work proposes a supervised Deep Learning approach for damage identification in bridge structures. We employ a hybrid methodology that incorporates Finite Element simulations to enrich the training phase of a Deep ... -
Uniqueness for solutions of the Schrödinger equation on trees
Fernández Bertolin, Aingeru; Jaming, Philippe (Fondazione Annali di Matematica Pura ed Applicata and Springer Nature, 2019-08-30)
We prove that if a solution of the time-dependent Schrödinger equation on an homogeneous tree with bounded potential decays fast at two distinct times then the solution is trivial. For the free Schrödinger operator, we use ...
