On the group of similitudes and its projective group
(1957)[Abstract]: Given a vector space nr over a field, with a non-degenerate quadratic form Q, we consider the linear transformations S which take any vector x ϵ nr into a vector xS such that Q(xS).= ρQ(x), where ρ ≠ 0 ... -
On the Influence of VOCs on New Particle Growth in a Continental-Mediterranean Region
(IOP Sciencie, 2022-12-30)[Abstract] A field campaign has been performed in the Madrid region to study the VOC influence in the growth of new particles in ambient air. A number of instruments have been deployed to characterize the main pollutant ... -
On the intrinsic instability of the advective-diffusive transport
(2004)[Abstract] A new theory for the advective–diffusive phenomenon is described in this study and the causes for the failure of the conventional numerical methods for this problem are investigated. It is shown that Fick’s law ... -
On the Logistical Difficulties and Findings of Jopara Sentiment Analysis
(Association for Computational Linguistics, 2021-06)[Abstract] This paper addresses the problem of sentiment analysis for Jopara, a code-switching language between Guarani and Spanish. We first collect a corpus of Guarani-dominant tweets and discuss on the difficulties of ... -
On the meaning and use of the terms, ‘erosion’and ‘exhumation’
(2017)[Abstract] It is important that technical terms with agreed meanings are used correctly. This applies particularly to words that reflect their etymology. Neglect of this principle distorts information and compromises the ... -
On the mineralogy of the O Casteliño spodumene pegmatite near Lalín, Galicia, Spain
(Universidade da Coruña, 1981)[Abstract] The mineralogy of a spodumene-bearing pegmatite from northwestern Spain is briefly described. Analyses of spodumene, tantalite and wodginite are given -
On the Multiplicity of Solutions of Taylor Linear Sources Generating Symmetrical Power Patterns with Filled Nulls
(Institute of Electrical and Electronics Engineers, 2004-12)[Abstract] As expressed in earlier works, if filled nulls are required in a power pattern generated by a Taylor line source, their corresponding roots must be complex. This leads to a multiplicity of solutions emerged from ... -
On the performance of phonetic algorithms in microtext normalization
(Elsevier, 2018-12-15)[Abstract]: User–generated content published on microblogging social networks constitutes a priceless source of information. However, microtexts usually deviate from the standard lexical and grammatical rules of the language, ... -
On the Physical Properties of Mixtures of Nitrate Salts and Protic Ionic Liquids
(Elsevier, 2022-01-19)[Abstract] We report a systematic study of the effect of salt concentration and its cation valence on several equilibrium and transport properties of mixtures of the model protic ionic liquid ethylammonium nitrate with ... -
On the Political Economy of Fines. Rusche and Kirchheimer’s Punishment and Social Structure Revisited
(2020)[Abstract]: This paper addresses the evolution of socio-legal theories concerning the use of monetary sanctions from a specific theoretical perspective – the “political economy of punishment” originally developed by ... -
On the Presence of a Giant Bristle Worm (Eunice roussaei) IN NW Iberian Peninsula: Comments on Its Taxonomy and Reproductive Cycle
(Elsevier, 2022-05-24)[Abstract] The presence of a giant “polychaete” annelid of the genus Eunice has been recently recorded in the Ría de Arousa (Galicia, NW Spain). Since Eunice spp. are highly appreciated as bait for recreational fishing in ... -
On the Presence of Prionospio Pulchra (Polychaeta: Spionidae) in the Atlantic Ocean
(Station Biologique de Roscoff, 2000)[Abstract] The presence of the Japanese spionid polychaete Prionospio pulchra in the Atlantic Ocean is confirmed by specimens found in the north-west coast of Spain (Iberian Peninsula). This species is characterized by ... -
On the Processing and Analysis of Microtexts: From Normalization to Semantics
(M D P I AG, 2018-09-18)[Abstract] User-generated content published on microblogging social platforms constitutes an invaluable source of information for diverse purposes: health surveillance, business intelligence, political analysis, etc. We ... -
On the Property Reading of Middles
(Universidade da Coruña, 2008)[Abstract] The English middle construction (This book reads well) is usually approached from the point of view of the derivational operations that account for the transitivity alternation. However, hardly any attention has ... -
On the relationship between society and higher education: what path should we take?
(Routledge/Francis & Taylor, 2018)[Abstract]: The current network society, with its primacy of information and communication technologies, is challenging the higher education model. The needs and expectations of today’s students ... -
On the Reliability of Machine Learning Models for Survival Analysis When Cure Is a Possibility
(MDPI, 2023-10-02)[Abstract]: In classical survival analysis, it is assumed that all the individuals will experience the event of interest. However, if there is a proportion of subjects who will never experience the event, then a standard ... -
On the resolution of the viscous incompressible flow for various SUPG finite element formulations
(The International Center of Numerical Methods in Engineering, 2000)[Abstract] A Finite Element based program has been released to solve the steady 2D Navier- Stokes equations. The mixed-variable algorithm is used as a first approach to solve the differential problem. In order to reduce ... -
On the scalability of feature selection methods on high-dimensional data
(Springer, 2018)[Abstract]: Lately, derived from the explosion of high dimensionality, researchers in machine learning became interested not only in accuracy, but also in scalability. Although scalability of learning methods is a trending ... -
On the semantics of hybrid ASP systems based on Clingo
(MDPI, 2023-03)[Abstract]: Over the last decades, the development of Answer Set Programming (ASP) has brought about an expressive modeling language powered by highly performant systems. At the same time, it gets more and more difficult ...
