      A Deep Double Ritz Method (D2RM) for solving Partial Differential Equations using Neural Networks 

      Uriarte Baranda, Carlos; Pardo Zubiaur, David ORCID; Muga, Ignacio; Muñoz Matute, Judit (Elsevier, 2023-02)
      Residual minimization is a widely used technique for solving Partial Differential Equations in variational form. It minimizes the dual norm of the residual, which naturally yields a saddle-point (min–max) problem over the ...

      A Fair and Scalable Mechanism for Resource Allocation: The Multilevel QPQ Approach 

      Doncel Vicente, Josu ORCID; 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 ...

      A general insertion theorem for uniform locales 

      Arrieta Torres, Igor; Avilez, Ana Belén (Elsevier, 2023-07)
      A general insertion theorem due to Preiss and Vilimovský is extended to the category of locales. More precisely, given a preuniform structure on a locale we provide necessary and sufficient conditions for a pair f ≥ g ...

      A geometric and physical study of Riemann's non-diferentiable function. 

      Eceizabarrena Pérez, Daniel (2020-07-08)
      Riemann's non-differentiable function is a classic example of a continuous but almost nowheredifferentiable function, whose analytic regularity has been widely studied since it was proposedin the second half of the 19th ...

      A revisited branch-and-cut algorithm for large-scale orienteering problems 

      Kobeaga Urriolabeitia, Gorka ORCID; Rojas Delgado, Jairo; Merino Maestre, María ORCID; Lozano Alonso, José Antonio (Elsevier, 2024-02)
      The orienteering problem is a route optimization problem which consists of finding a simple cycle that maximizes the total collected profit subject to a maximum distance limitation. In the last few decades, the occurrence ...

      A theory of quantale-enriched dcpos and their topologization 

      Gutiérrez García, Francisco Javier; Höhle, Ulrich; Kubiak, Tomasz (Elsevier, 2022-09)
      There have been developed several approaches to a quantale-valued quantitative domain theory. If the quantale Q is integral and commutative, then Q-valued domains are Q-enriched, and every Q-enriched domain is sober in ...

      A Universal Antigen-Ranking Method to Design Personalized Vaccines Targeting Neoantigens against Melanoma 

      Malaina Celada, Iker ORCID; Martínez Fernández, Luis ORCID; Montoya, Juan Manuel; Alonso Alegre, Santos ORCID; Boyano López, María Dolores ORCID; Asumendi Mallea, Aintzane ORCID; Izu Belloso, Rosa María; Sánchez Díez, Ana; Cancho Galán, Goikoane; Martínez de la Fuente Martínez, Ildefonso Abel (MDPI, 2023-01-05)
      Background: The main purpose of this article is to introduce a universal mathematics-aided vaccine design method against malignant melanoma based on neoantigens. The universal method can be adapted to the mutanome of each ...

      Advanced mathematical modelling of pancreatic B-cells 

      Marinelli, Isabella (2019-12-10)
      [EN*Insulin-secreting pancreatic ß-cells are responsible for maintaining the whole body glucosehomeostasis. Dysfunction or loss of ß-cell mass results in impaired insulin secretion and, in somecases, diabetes. In this ...

      Age of Information in a Decentralized Network of Parallel Queues with Routing and Packets Losses 

      Doncel Vicente, Josu ORCID; Assaad, Mohamad (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 ORCID (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 ...

      Age or lifestyle-induced accumulation of genotoxicity is associated with a length-dependent decrease in gene expression 

      Ibáñez Solé, Olga; Barrio Beraza, Irantzu; Izeta Permisán, Ander ORCID (Elsevier, 2023-04)
      DNA damage has long been advocated as a molecular driver of aging. DNA damage occurs in a stochastic manner, and is therefore more likely to accumulate in longer genes. The length-dependent accumulation of transcription-blocking ...
