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 ... -
Analysis of the Refined Mean-Field Approximation for the 802.11 Protocol Model
; Doncel Vicente, Josu (MDPI, 2022-11-12)
Mean-field approximation is a method to investigate the behavior of stochastic models formed by a large number of interacting objects. A new approximation was recently established, i.e., the refined mean-field approximation, ... -
Approximate zero-crossing: a new interpretable, highly discriminative and low-complexity feature for EEG and iEEG seizure detection.
(IOP, 2022)Objective. Long-term monitoring of people with epilepsy based on electroencephalography (EEG) and intracranial EEG (iEEG) has the potential to deliver key clinical information for personalised epilepsy treatment. More ... -

Associative Conditioning Is a Robust Systemic Behavior in Unicellular Organisms: An Interspecies Comparison
; ; Malaina Celada, Iker; ; Martínez Fernández, Luis ; Pérez-Yarza Pérez-Irezabal, Gorka ; Boyano López, María Dolores ; ; ; ; ; (Frontiers Media, 2021-07-19)
The capacity to learn new efficient systemic behavior is a fundamental issue of contemporary biology. We have recently observed, in a preliminary analysis, the emergence of conditioned behavior in some individual amoebae ... -
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 ... -
Automatic Analysis of Archimedes’ Spiral for Characterization of Genetic Essential Tremor Based on Shannon’s Entropy and Fractal Dimension
(MDPI, 2018-07)Among neural disorders related to movement, essential tremor has the highest prevalence; in fact, it is twenty times more common than Parkinson's disease. The drawing of the Archimedes' spiral is the gold standard test to ... -
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 ... -
Binormal Motion of Curves with Constant Torsion in 3-Spaces
Arroyo Olea, Yosu; ; Pámpano Llarena, Álvaro (Hindawi, 2017)
We study curve motion by the binormal flow with curvature and torsion depending velocity and sweeping out immersed surfaces. Using the Gauss-Codazzi equations, we obtain filaments evolving with constant torsion which arise ... -
CALE: Learning by Example in Mathematics with Applets in Mathematical Computational Packages
Martínez Fernández, Luis; ; ; Malaina Celada, Iker ; Mardones Pérez, Iraide (MDPI, 2018-10-28)
In this work we present a methodology of “learning by example” assisted by computers in the study of mathematics. We propose the use of mathematical computational packages to program applets aimed to solve mathematical ... -
Cell Motility and Cancer
(MDPI, 2020-08-05)Cell migration is an essential systemic behavior, tightly regulated, of all living cells endowed with directional motility that is involved in the major developmental stages of all complex organisms such as morphogenesis, ... -

Esteban, Cristóbal; Arostegui Madariaga, Inmaculada; Aramburu, Amaia; Moraza, Javier; Aburto, Myriam; Aizpiri, Susana; Chasco, Leyre; Quintana López, José María (European Respiratory Society, 2022-01)
[EN] Chronic obstructive pulmonary disease (COPD) is understood as a complex, heterogeneous and multisystem airway obstructive disease. The association of deterioration in health-related quality of life (HRQoL) with mortality ... -
Changes in the simulation of atmospheric instability over the Iberian Peninsula due to the use of 3DVAR data assimilation
; ; Sáenz Aguirre, Jon; (Copernicus Publications, 2021-06-18)
[EN] Abstract. The ability of two downscaling experiments to correctly simulate thermodynamic conditions over the Iberian Peninsula (IP) is compared in this paper. To do so, three parameters used to evaluate the unstable ... -
Characterizing Permutation-Based Combinatorial Optimization Problems in Fourier Space
; Hernando Rodríguez, Leticia; (MIT Press, 2023-09-01)
[EN]Comparing combinatorial optimization problems is a difficult task. They are defined using different criteria and terms: weights, flows, distances, etc. In spite of this apparent discrepancy, on many occasions, they ... -
