Ultra-Performance Liquid Chromatography-Ion Mobility Separation-Quadruple Time-of-Flight MS (UHPLC-IMS-QTOF MS) Metabolomics for Short-Term Biomarker Discovery of Orange Intake: A Randomized, Controlled Crossover Study
MDPI (2020)A major problem with dietary assessments is their subjective nature. Untargeted metabolomics and new technologies can shed light on this issue and provide a more complete picture of dietary intake by measuring the profile ... -
Ultra-processed foods consumption as a promoting factor of greenhouse gas emissions, water, energy, and land use: A longitudinal assessment
Elsevier (2023)Background: Dietary patterns can produce an environmental impact. Changes in people's diet, such as the increased consumption of ultra-processed food (UPF) can not only influence human health but also environment ... -
Un sistema de Realidad Virtual distribuido basado en la gestión de recursos federados
Asociación de Técnicos de Informática (2009)The vast majority of distributed virtual environments use ad-hoc protocols to share resources and synchronize the interaction of multiple users on a shared virtual world. In this scenario, it is difficult to incorporate ... -
Uncooperative gait recognition by learning to rank
Elsevier (2014)Gait is a useful biometric because it can operate from a distance and without subject cooperation. However, it is affected by changes in covariate conditions (carrying, clothing, view angle, etc.). Existing methods suffer ... -
Understanding the sharing economy and its implication on sustainability in smart cities
Elsevier (2020-09-06)The purpose of this article is to evaluate the main drivers of the sharing economy through an exhaustive weighting and meta-analysis of previous relevant quantitative research articles, obtained using a systematic literature ... -
Unsupervised Remote Sensing Image Retrieval Using Probabilistic Latent Semantic Hashing
Institute of Electrical and Electronics Engineers (2020-02-06)Unsupervised hashing methods have attracted considerable attention in large-scale remote sensing (RS) image retrieval, due to their capability for massive data processing with significantly reduced storage and computation. ... -
Upper bounds for the Poincaré recurrence time in quantum mixed states
IOP Publishing Ltd. (2017-04)In this paper we use geometric techniques to provide upper bounds for the Poincaré recurrence time of a quantum mixed state with a discrete spectrum of energies. We obtain two types of upper bounds. One of them depends on ... -
Use of ensemble based on GA for imbalance problem
Springer Verlag (Germany) (2009)In real-world applications, it has been observed that class imbalance (significant differences in class prior probabilities) may produce an important deterioration of the classifier performance, in particular with patterns ... -
Use of social networks as a CSR communication tool
Cogent OA (2016-05-30)The aim of this paper is to analyse the use of online social networks as a tool for Corporate Social Responsibility (CSR) communication and management. To this end, an analysis was performed of the messages posted by the ... -
User-assisted simplification method for triangle meshes preserving boundaries
Elsevier (2009)This paper proposes a user-assisted mesh simplification method applied to CAD models converted to triangle meshes. This work offers the possibility of simplifying each subobject independently and at different levels of ... -
Using Big Data for Sustainability in Supply Chain Management
MDPI (2021)In the literature, several frameworks have been proposed to help sustainability management in supply chains. Nevertheless, they present a number of shortcomings. With the aim of overcoming these shortcomings, this paper ... -
Using big data to evaluate corporate social responsibility and sustainable development practices
Wiley (2020-07-27)This paper shows an alternative method to evaluate sustainable development and corporate social responsibility (CSR) practices based on the opinions of companies' stakeholders expressed on Twitter. An application of the ... -
Using hybrid associative classifier with translation (HACT) for studying imbalanced data sets
Universidad Nacional de Colombia (Sede Bogotá). Facultad de Ingeniería (2012)En diversos problemas de reconocimiento de patrones, se ha observado que el desequilibrio de clases puede disminuir el desempeño del clasificador, principalmente en los patrones de las clases minoritarias. Una estrategia ... -
Using Semantic Web Technologies for Exploratory OLAP: A Survey
Institute of Electrical and Electronics Engineers (IEEE) (2015-02)This paper describes the convergence of some of the most influential technologies in the last few years, namely data warehousing (DW), on-line analytical processing (OLAP), and the Semantic Web (SW). OLAP is used by ... -
