Semiorders and continuous Scott–Suppes representations. Debreu’s Open Gap Lemma with a threshold
The problem of finding a utility function for a semiorder has been studied since 1956, when the notion of semiorder was introduced by Luce. But few results on continuity and no result like Debreu’s Open Gap Lemma, but for ... -
Quadcopter neural controller for take-off and landing in windy environments
(Elsevier, 2023) Artículo / ArtikuluaThis paper proposes the design of a quadcopter neural controller based on Reinforcement Learning (RL) for controlling the complete maneuvers of landing and take-off, even in variable windy conditions. To facilitate RL ... -
Association of intrinsic capacity with incidence and mortality of cardiovascular disease: prospective study in UK Biobank
Background: The World Health Organization proposed the concept of intrinsic capacity (IC; the composite of all the physical and mental capacities of the individual) as central for healthy ageing. However, little research ... -
Achieving transfer from mathematics learning
The question of transfer is a special challenge in mathematics teaching because the wide range and fragmentation of the curricula have in many cases fostered an instrumental understanding, which makes transfer difficult ... -
Analysis of bright bolides recorded between October and November 2022 by the Southwestern Europe Meteor Network
We present in this work the analysis of some of the bright fireballs spotted in the framework of the Southwestern Europe Meteor Network (SWEMN) between October and November 2022. They have been observed from the Iberian ... -
The Southwestern Europe Meteor Network: notable meteors spotted between December 2022 and January 2023
We present in this report the analysis of some of the notable meteors registered in the framework of the Southwestern Europe Meteor Network between December 2022 and January 2023. These were recorded from Spain. Their peak ... -
On the notion of fuzzy dispersion measure and its application to triangular fuzzy numbers
In this paper, based on the analysis of the most widely used dispersion measure in the real context (namely, the variance), we introduce the notion of fuzzy dispersion measure associated to a finite set of data given by ... -
Generalizing max pooling via (a, b)-grouping functions for convolutional neural networks
Due to their high adaptability to varied settings and effective optimization algorithm, Convolutional Neural Networks (CNNs) have set the state-of-the-art on image processing jobs for the previous decade. CNNs work in a ... -
An enhanced approach to virtually increase quasi-stationarity regions within geometric channel models for vehicular communications
Vehicular communication channels are intrinsically non-stationary, as they present high mobility and abundant dynamic scatterers. Quasi-stationary regions can assess the degree of non-stationarity within a determined ... -
High-dimensional order-free multivariate spatial disease mapping
Despite the amount of research on disease mapping in recent years, the use of multivariate models for areal spatial data remains limited due to difficulties in implementation and computational burden. These problems are ... -
Measures of embedding for interval-valued fuzzy sets
Interval-valued fuzzy sets are a generalization of classical fuzzy sets where the membership values are intervals. The epistemic interpretation of interval-valued fuzzy sets assumes that there is one real-valued membership ... -
Existence of almost greedy bases in mixed-norm sequence and matrix spaces, including besov spaces
We prove that the sequence spaces lp ⊕ lq and the spaces of infinite matrices lp(lq ), lq l(p) and ( ∞ n=1 n lp)lq , which are isomorphic to certain Besov spaces, have an almost greedy basis whenever 0 < p < 1 < q < ∞. ... -
Asymptotic expansions for Moench's integral transform of hydrology
Theis' theory (1935), later improved by Hantush & Jacob (1955) and Moench (1971), is a technique designed to study the water level in aquifers. The key formula in this theory is a certain integral transform H[g](r,t) of ... -
Quantifying external information in social network analysis: an application to comparative mythology
Social network analysis is a popular tool to understand the relationships between interacting agents by studying the structural properties of their connections. However, this kind of analysis can miss some of the domain-specific ... -

Este artículo analiza el grado y el tipo de motivación en 97 estudiantes deespañol L2 universitarios en un programa de estudios en el extranjero(PREE). También indaga sobre el efecto del contacto conhispanohablantes ... -
Acuity-based rotational patient-to-physician assignment in an emergency department using electronic health records in triage
Emergency department (ED) operational metrics generated by a new acuity-based rotational patient-to-physician assignment (ARPA) algorithm are compared with those obtained with a simple rotational patient assignment (SRPA) ... -
Hierarchical spatio-temporal change-point detection
Detecting change-points in multivariate settings is usually carried out by analyzing all marginals either independently, via univariate methods, or jointly, through multivariate approaches. The former discards any inherent ... -
Systematic review of aggregation functions applied to image edge detection
Edge detection is a crucial process in numerous stages of computer vision. This field of study has recently gained momentum due to its importance in various applications. The uncertainty, among other characteristics of ... -
Valorization of agri-food waste through the extraction of bioactive molecules. Prediction of their sunscreen action
The aim of this work was to identify the phenolic composition of 18 different vegetable residues and to determine the relationship between their phenolic compounds, antioxidant capacity and sun protection factor. For ... -
VTOL UAV digital twin for take-off, hovering and landing in different wind conditions
With UAVs becoming increasingly popular in the industry, vertical take-off and landing (VTOL) convertiplanes are emerging as a compromise between the advantages of planes and multicopters. Due to their large wing surface ...
