Visualising quantum innovation: A regional case study
At the beginning of this century, the advent of a second generation of 'quantum technologies' was announced together with its revolutionary potential to change existing information technologies. Despite the rapidly increasing ...
Measurement of CP asymmetries in Λ_b^0→ph^- decays
A search for CP violation in Λ_b^0 -> pK^- and Λ_b^0 -> pπ^- decays is presented using the full Run 1 and Run 2 data samples of pp collisions collected with the LHCb detector, corresponding to an integrated luminosity of ...
Search for the resonance-enhanced CP and angular asymmetries in the Λ_c^+→pμ^+ μ^- decay at LHCb
The first measurement of the CP asymmetry of the decay rate (A_CP) and the CP average (Sigma A_FB) and CP asymmetry (Delta A_FB) of the forward-backward asymmetry in the muon system of Λ_c^+ -> pμ^+ μ^- decays is reported. ...
A simple nonparametric approach to pricing credit default swaps
This study introduces a nonparametric approach to pricing credit default swaps (CDSs) and other single-name credit-risky securities. This method is notable for its simplicity, estimation speed, and flexibility. That is, ...
AI-driven Optimization of project portfolios in corporate ecosystems with synergies and strategic factors
This paper studies the optimization of project portfolios in corporate ecosystems by considering both strategic factors and return synergies between projects. We propose a hybrid method that combines machine learning with ...
Memoria de publicaciones de Derecho Romano año 2024
La Memoria de Publicaciones de Derecho Romano año 2024 que presentamos tiene como objetivo principal la recopilación y presentación de los trabajos de investigación de Derecho Romano publicados a lo largo del año 2024, y ...
The impact of conversational AI on consumer decision-making: A systematic review and cluster analysis
This study presents a comprehensive analysis of the influence of conversational artificial intelligence (AI)—a subset of AI that enables machines to simulate human-like conversations through natural language processing ...
Balancing Success: The Secrets of Female Entrepreneurs in Leadership and Personal Life
This study explores successful female entrepreneurs’ characteristics, motivations, and leadership styles, emphasizing the impact of digital transformation on their business practices. Through 15 in-depth interviews conducted ...
La justicia internacional y las obligaciones de mitigación del cambio climático: Retos procesales y sistémicos
Este estudio analiza la incipiente la justicia climática internacional a través de la jurisprudencia del TEDH, la CIDH y el TIDM sobre las obligaciones de mitigación del cambio climático. Examina en primer lugar la dificultad ...
Experience-Sampling Approach to Emotion Differentiation and Bipolar Mood Risk in Emerging Adults
Despite the prominence of emotion disturbance in bipolar disorder, few studies have assessed emotion differentiation. The present investigation used an experience-sampling approach to test the utility of emotion differentiation ...
Risk mitigation through noise reduction in hierarchical portfolio selection
Risk parity portfolio methods rely solely on covariance estimates to minimize risk, ignoring expected returns due to their high estimation error. This approach can be unstable when dealing with a reduced number of observations. ...
Toward sustainability: ESG bridging socioemotional wealth and sustainable financial in family firms
The socioemotional wealth of family businesses fosters long-term orientation, aligning with the environmental, social, and governance (ESG) principles essential for sustainable value creation. This study utilised panel ...
LLMs outperform outsourced human coders on complex textual analysis
This paper evaluates the effectiveness of large language models (LLMs) in extracting complex information from text data. Using a corpus of Spanish news articles, we compare how accurately various LLMs and outsourced human ...
Analysis of Training Behavior in Users of a Fitness App: Cross-Sectional Study
Background: Mobile health (mHealth) apps are increasingly being used to promote physical activity (PA) and can support exercise uptake and maintenance. Despite their potential, these tools face high dropout rates and ...
Potential of facial biomarkers for Alzheimer's disease and obstructive sleep apnea in Down syndrome and general population
Down syndrome (DS), caused by trisomy 21, is associated with an increased risk of Alzheimer's disease (AD) and obstructive sleep apnea (OSA). Traditional diagnostic methods for AD and OSA, like cerebrospinal fluid analysis ...
Aprendizaje activo en la educación superior de ingeniería: un decálogo para diseñar quizzes online post-clase
Los quizzes son una valiosa herramienta entre las diversas estrategias de aprendizaje activo en la educación superior. En contextos de aprendizaje a distancia se utilizan con frecuencia para evaluar el nivel de conocimientos ...
First Observation of the B ¯ s0 → Λc+ Λ ¯ c- Decay and Evidence for the B ¯ 0 → Λc+ Λ ¯ c- Decay
A search is presented for the two-body charmed baryonic decays, B¯(s)0→Λc+Λ¯c-, using a data sample collected by the LHCb experiment during 2011-2012 and 2015-2018, corresponding to an integrated luminosity of 9 fb-1. The ...
Study of Ds1(2460)+→Ds+π+π- in B→D¯(*)Ds+π+π- decays
An amplitude analysis of the Ds1(2460)+→Ds+π+π- transition is performed simultaneously in B0→D-Ds+π+π-, B+→D¯0Ds+π+π-, and B0→D*-Ds+π+π- decays. The study is based on a data sample of proton-proton collisions recorded with ...
Measurement of exclusive J/ψ and ψ(2S) production at ps = 13 TeV
Measurements are presented of the cross-section for the central exclusive production of J/ψ → µ+µ− and ψ(2S) → µ+µ− processes in proton-proton collisions at ps = 13 TeV with 2016–2018 data. They are performed by requiring ...
First evidence of CP violation in beauty baryon to charmonium decays
A study of the difference in the CP asymmetries between Λb0→J/ψpπ- and Λb0→J/ψpK- decays, ΔACP, is performed using proton-proton collision data collected by the LHCb experiment in the years 2015–2018, corresponding to an ...
