Minimum projective linearizations of trees in linear time
(2022-03)
Article
Open AccessThe Minimum Linear Arrangement problem (MLA) consists of finding a mapping π from vertices of a graph to distinct integers that minimizes {u,v}∈E |π(u) − π(v)|. In that setting, vertices are often assumed to lie on a ... -
Infographics, a better medium than plain text for increasing knowledge
(2021-09-16)
Article
Open AccessInfographics in social networks present more elaborate proposals than simple text. In this study we analyze the general patterns of Twitter infographic messages to determine its main characteristics. Subsequently, we ... -
Más allá de la teoría de la mente: nuevos modelos desde la lingüística cognitiva
(Prensa científica, 2021-09)
Article
Restricted access - publisher's policyLa idea de que nuestros actos lingüísticos nos ubican socialmente no es nada nueva: de hecho, nuestro idiolecto nos delata doquiera que vayamos. Así, al menos en nuestra lengua materna, somos capaces de detectar con más o ... -
Desnudar la inteligencia artificial mientras la vestimos
(2021-09)
Article
Restricted access - publisher's policy¿Qué es la inteligencia artificial? ¿Qué sesgos o ideologías políticas propaga, y para quién? ¿Qué coste ambiental tiene? ¿Debería limitarse su uso? Tras la publicación de "Atlas of AI" de Kate Crawford (Yale Univ. Press, ... -
Can Menzerath’s law be a criterion of complexity in communication?
(Public Library of Science (PLOS), 2021-08-20)
Article
Open AccessMenzerath’s law is a quantitative linguistic law which states that, on average, the longer is a linguistic construct, the shorter are its constituents. In contrast, Menzerath-Altmann’s law (MAL) is a precise mathematical ... -
Fostering sustainability and critical thinking through debate: a case study
(2021-06)
Article
Open AccessTransversal competences such as sustainability or critical thinking have become more important in the last decades in University teaching. The objective of this article is to assess the effectiveness of debate as a teaching ... -
Qualitative and quantitative examples of natural and artificial phenomena
(2021-05-24)
Article
Restricted access - publisher's policyThe dichotomy between the qualitative and the quantitative has been a classic throughout the history of science. As will be seen, this dichotomy permeates all ontological levels of reality. In this work, phenomenological ... -
Knowledge-based segmentation to improve accuracy and explainability in non-technical losses detection
(2020-10-30)
Article
Open AccessUtility companies have a great interest in identifying energy losses. Here, we focus on Non-Technical Losses (NTL), which refer to losses caused by utility theft or meter errors. Typically, utility companies resort to ... -
Bounds of the sum of edge lengths in linear arrangements of trees
(Institute of Physics (IOP), 2021-02-11)
Article
Restricted access - publisher's policyA fundamental problem in network science is the normalization of the topological or physical distance between vertices, which requires understanding the range of variation of the unnormalized distances. Here we investigate ... -
Distinct flavors of Zipf's law and its maximum likelihood fitting: Rank-size and size-distribution representations
(American Institute of Physics (AIP), 2020-11-10)
Article
Open AccessIn recent years, researchers have realized the difficulties of fitting power-law distributions properly. These difficulties are higher in Zipfian systems, due to the discreteness of the variables and to the existence of ... -
Reappraising the distribution of the number of edge crossings of graphs on a sphere
(Institute of Physics (IOP), 2020-08-01)
Article
Open AccessMany real transportation and mobility networks have their vertices placed on the surface of the Earth. In such embeddings, the edges laid on that surface may cross. In his pioneering research, Moon analyzed the distribution ... -
Weak-type and end-point norm estimates for Hardy operators
(2020-11)
Article
Restricted access - publisher's policyWe explicitly calculate the best constants for weak-type and other end-point estimates for the Hardy operator and its adjoint. In particular, we find the right value for decreasing power weights, fixing some previously ...
