The use of gerunds and infinitives in perceptive constructions
2016
In this article I compare the use of gerunds with perceptive verbs in Spanish and in Gardenese, a Rhaeto-Romance variety spoken in Northern Italy: perceptive gerunds are used as secondary predicates in Spanish, but as defective TP-complements in Gardenese. Following Rizzi’s (2014) account of parametric variation, I propose that the differences are due to the interplay of three parameters: a [+progressive] feature on Gardenese perception verbs, the pure lexical status of perception verbs in Gardenese and a [+Agreement] feature on Spanish gerunds. The discussion of the parameters involved leads to more general considerations, as a new proposal for the structure of perceptive ECMs in Romance, …
Design of the CGAL 3D Spherical Kernel and application to arrangements of circles on a sphere
2009
AbstractThis paper presents a cgal kernel for algorithms manipulating 3D spheres, circles, and circular arcs. The paper makes three contributions. First, the mathematics underlying two non-trivial predicates are presented. Second, the design of the kernel concept is developed, and the connexion between the mathematics and this design is established. In particular, we show how two different frameworks can be combined: one for the general setting, and one dedicated to the case where all the objects handled lie on a reference sphere. Finally, an assessment about the efficacy of the 3D Spherical Kernel is made through the calculation of the exact arrangement of circles on a sphere. On average w…
Standard vs random dictator games: On the effects of role uncertainty and framing on generosity
2021
This project was conducted while Ernesto Mesa-Vázquez was visiting Universidad Loyola Andalucia. He wants to particularly thank Pablo Brañas-Garza and Diego Jorrat for continued guidance and assessment with the experimental design. Álvaro Núñez-Bermúdez and the faculty members of the Economics and Business Sciences department at the University of Seville were very helpful in providing assistance for running the experiment. The paper has benefited from comments and suggestions provided by Maria Paz Espinosa, Giuseppe Attanassi, José Enrique Vila, Iván Arribas, Marco Faillo, Cristina Borra and participants at the Loyola Behavioral Lab and the Early Career Researchers in Experimental Economics…
An Innovative Structural Dynamic Identification Procedure Combining Time Domain OMA Technique and GA
2022
In this paper an innovative and simple Operational Modal Analysis (OMA) method for structural dynamic identification is proposed. It combines the recently introduced Time Domain–Analytical Signal Method (TD–ASM) with the Genetic Algorithm (GA). Specifically, TD–ASM is firstly employed to estimate a subspace of candidate modal parameters, and then the GA is used to identify the structural parameters minimizing the fitness value returned by an appropriately introduced objective function. Notably, this method can be used to estimate structural parameters even for high damping ratios, and it also allows one to identify the Power Spectral Density (PSD) of the structural excitat…
Distributed and Lumped Parameter Models for the Characterization of High Throughput Bioreactors
2016
Next generation bioreactors are being developed to generate multiple human cell-based tissue analogs within the same fluidic system, to better recapitulate the complexity and interconnection of human physiology. The effective development of these devices requires a solid understanding of their interconnected fluidics, to predict the transport of nutrients and waste through the constructs and improve the design accordingly. In this work, we focus on a specific model of bioreactor, with multiple input/outputs, aimed at gen- erating osteochondral constructs, i.e., a biphasic construct in which one side is cartilagi- nous in nature, while the other is osseous. We next develop a general computat…
A framework for remission in SLE
2017
ObjectivesTreat-to-target recommendations have identified ‘remission’ as a target in systemic lupus erythematosus (SLE), but recognise that there is no universally accepted definition for this. Therefore, we initiated a process to achieve consensus on potential definitions for remission in SLE.MethodsAn international task force of 60 specialists and patient representatives participated in preparatory exercises, a face-to-face meeting and follow-up electronic voting. The level for agreement was set at 90%.ResultsThe task force agreed on eight key statements regarding remission in SLE and three principles to guide the further development of remission definitions:1. Definitions of remission wi…
Comparing DNA sequence collections by direct comparison of compressed text indexes
2012
Popular sequence alignment tools such as BWA convert a reference genome to an indexing data structure based on the Burrows-Wheeler Transform (BWT), from which matches to individual query sequences can be rapidly determined. However the utility of also indexing the query sequences themselves remains relatively unexplored. Here we show that an all-against-all comparison of two sequence collections can be computed from the BWT of each collection with the BWTs held entirely in external memory, i.e. on disk and not in RAM. As an application of this technique, we show that BWTs of transcriptomic and genomic reads can be compared to obtain reference-free predictions of splice junctions that have h…
¿Tienen futuro las actividades agrarias tal y como las conocemos actualmente?
2015
Esta unidad didáctica se titula: ¿Tienen futuro las actividades agrarias tal y como las conocemos actualmente? y en ella se desarrollan las actividades agrarias del Sector Primario. Este tema tiene gran importancia en la vida cotidiana de todos los ciudadanos con mayor o menor incidencia, pero omnipresente. En este caso concreto, el tema adquiere mayor relevancia al contextualizar esta unidad didáctica en un instituto de la localidad de Requena (Valencia), con un alto índice de población activa en el sector primario y por lo tanto base económica de muchos de los alumnos a los que se dirige. Además de esto, los recursos procedentes de este sector son la base alimentaria del ser humano y en c…
Sustainable Infrastructure Projects: Systemic versus Traditional Delivery Models
2021
Sustainability involves multiple environmental, technical, social and economic factors, and such complex analysis requires systemic solutions. Delivery models are key to achieving system benefits and enhancing sustainable development in infrastructure investments. They define the phases of a project, incentive structures, risk sharing and the relationships among the actors in it. They are usually developed early in the project and determine the project dynamics and outcomes. We compared traditional delivery models with systemic ones. We identified and illustrated elements that differ between them through two cases. The contribution is an increased understanding of how systemic infrastructur…
Reliability Analysis of a Controlled Stage-Constructed and Reinforced Embankment on Soft Ground Using 2D and 3D Models
2020
Geosynthetic reinforcement has become a very practical technique to improve geotechnical structure safety. In spite of improved soil behavior, structures are affected by uncertainties related to soil and reinforcement material properties. This paper aims to present a reliability analysis in order to take statistical information (uncertainties) into account in a safety analysis of reinforced embankments. The analysis was used in a case study on a controlled stage-constructed embankment on soft ground in order to investigate its probabilistic stability. Modeling was performed by commercial geotechnical software usage (GeoStudio and RocScience packs, SIGMA/W+SLOPE/W and SLIDE³, respectively) a…
