Paleogenomic evidence for multi-generational mixing between Neolithic farmers and Mesolithic hunter-gatherers in the lower Danube basin
(Cell, 2017-05-25)[Abstract] The transition from hunting and gathering to farming involved profound cultural and technological changes. In Western and Central Europe, these changes occurred rapidly and synchronously after the arrival of ... -
Parallel construction of wavelet trees on multicore architectures
(Springer U K, 2016-10-05)[Abstract] The wavelet tree has become a very useful data structure to efficiently represent and query large volumes of data in many different domains, from bioinformatics to geographic information systems. One problem ... -
Parsing as Pretraining
(2020)[Abstract] Recent analyses suggest that encoders pretrained for language modeling capture certain morpho-syntactic structure. However, probing frameworks for word vectors still do not report results on standard setups ... -
PDE Models for the Pricing of a Defaultable Coupon-Bearing Bond Under an Extended JDCEV Model
(Elsevier, 2021)[Abstract] We consider a two-factor model for the pricing of a non callable defaultable bond which pays coupons at certain given dates. The model under consideration is the Jump to Default Constant Elasticity of Variance ... -
Perceptual Generalization and Context in a Network MemoryInspired Long-Term Memory for Artificial Cognition
(World Scientific Publishing Company, 2019)Abstract: In the framework of open-ended learning cognitive architectures for robots, this paper deals with thedesign of a Long-Term Memory (LTM) structure that can accommodate the progressive acquisition ofexperience-based ... -
Planetary Nebulae in Gaia EDR3: Central Star Identification, Properties, and Binarity
(EDP Science, 2021)[Abstract] Context. The Gaia Early Data Release 3 (EDR3), published in December 2020, features improved photometry and astrometry compared to that published in the previous DR2 file and includes a substantially larger ... -
Planificación y distribución óptima de cargas en un sistema de evaporadores industriales
(Comité Español de Automática, 2016)[Resumen] En este trabajo se presenta la resolución de un problema de asignación temporal de recursos, así como el reparto de cargas en varias líneas de evaporación industrial. Dichos evaporadores tienen diferente rendimiento ... -
Plastic Debris in Lakes and Reservoirs
(Springer Nature, 2023)[Abstract] Plastic debris is thought to be widespread in freshwater ecosystems globally1. However, a lack of comprehensive and comparable data makes rigorous assessment of its distribution challenging2,3. Here we present ... -
Polymer-Induced Biofilms for Enhanced Biocatalysis
(Royal Society of Chemistry, 2022-07-21)[Abstract] The intrinsic resilience of biofilms to environmental conditions makes them an attractive platform for biocatalysis, bioremediation, agriculture or consumer health. However, one of the main challenges in these ... -
Polymorphism in Non-Fullerene Acceptors Based on Indacenodithienothiophene
(Wiley, 2021)[Abstract] Organic solar cells incorporating non-fullerene acceptors (NFAs) have reached remarkable power conversion efficiencies of over 18%. Unlike fullerene derivatives, NFAs tend to crystallize from solutions, resulting ... -
Los primeros robots manipuladores aéreos
(Comité Español de Automática, 2016)[Resumen] En este artículo se describen los primeros robots manipuladores aéreos dotados con brazos robóticos de seis grados de libertad y capacidades de percepción y planificación que se han desarrollado en el mundo. Estos ... -
Probability of default estimation in credit risk using mixture cure models
(Elsevier, 2024-01)[Abstract]: An estimator of the probability of default (PD) in credit risk is proposed. It is derived from a nonparametric conditional survival function estimator based on cure models. Asymptotic expressions for the bias ... -
Probing Tyrosine Nitration with a Small TbIII-Metallopeptide
(Wiley, 2023-06-06)[Abstract] Tyrosine nitration, a post-translational modification (PTM) that takes place under nitrosative stress conditions, occurs through a non-enzymatic peroxynitrite-mediated reaction. Although protein nitration has ... -
Production and characterization of an extracellular acid protease from thermophilic Brevibacillus sp. OA30 isolated from an Algerian hot spring
(MDPI, 2018-04-12)[Abstract] Proteases have numerous biotechnological applications and the bioprospection for newly-thermostable proteases from the great biodiversity of thermophilic microorganisms inhabiting hot environments, such as ... -
Prototype of an Entity Recognition System for Antimicrobial Resistance Data Management
(Universidade da Coruña, Servizo de Publicacións, 2023)[Abstract] Often, a study or research process requires the analysis of large volumes of information in the form of unstructured text. This task consumes a large amount of time and resources of the human experts in charge ... -
Quantifying the role of individual flood drivers and their correlations in flooding of coastal river reaches
(Springer, 2019)[Abstract:] Flooding in coastal river reaches is the result of complex interactions between coastal and inland drivers. Flood hazard assessments need to consider how these drivers interact in space and time, for which a ... -
Quantum Arithmetic for Directly Embedded Arrays
(MDPI, 2021)[Abstract] We describe a general-purpose framework to implement quantum algorithms relying upon an efficient handling of arrays. The cornerstone of the framework is the direct embedding of information into quantum amplitudes, ... -
Quantum Computing for Dealing with Inaccurate Knowledge Related to the Certainty Factors Model
(MDPI, 2022)[Abstract] In this paper, we illustrate that inaccurate knowledge can be efficiently implemented in a quantum environment. For this purpose, we analyse the correlation between certainty factors and quantum probability. We ... -
Rationale and Design of a Scope 3 Capital Charge
(Universidade da Coruña, Servizo de Publicacións, 2023)[Abstract] Climate change is caused by greenhouse gas emissions, and governments have introduced over seventy carbon pricing instruments (CPIs). Banks finance a significant fraction of global emissions, and many have ... -
Reactive transport modelling of a low-pH concrete / clay interface
(Elsevier, 2020)[Abstract:] Cement-based materials are key components in the barrier system and structural support of repositories for disposal of nuclear waste. As such, increased understanding of their long-term performance under ...
