Nutritional characterization of Butternut squash (Cucurbita moschata D.): Effect of variety (Ariel vs. Pluto) and farming type (conventional vs. orga…

2019

Farming systems and cultivar types are two of the main factors able to affect the nutritional quality of plant foods for human nutrition. Therefore, the aim of this study was to compare the impact of two unexplored variety (namely Ariel and Pluto) and farming type (conventional and organic) on physicochemical parameters, chemical and mineral composition, water- and fat-soluble vitamins, amino acid profile and antioxidant bioactive components of butternut squashes (Cucurbita moschata). In order to achieve this purpose, a multivariate statistical discrimination of the different parameters was carried out using the unsupervised principle component analysis (PCA). The most important differences…

Satisfacción con la vida, sintomatología depresiva, y soledad en víctimas de cyberbullying

2019

El cyberbullying es un problema creciente y grave que suscita mucha preocupación social. Laevidencia empírica muestra que los adolescentes victimizados muestran mayor malestar psicológico, y sufren rechazo por parte de sus compañeros. El objetivo del presente trabajo fue analizar las diferencias existentes en las variables satisfacción con la vida, sintomatología depresiva, y soledad de las cibervíctimas en función de la duración de este tipo de intimidación (no me ha pasado, 1 mes (o menos), entre 3 y 6 meses, y 1 año (o más)). Además, se analizó el valor predictivo de las variables objeto de estudio en la cibervictimización. La muestra estuvo formada por 785 adolescentes (53.4% chicos y 4…

A continuous time tug-of-war game for parabolic $p(x,t)$-Laplace type equations

2019

We formulate a stochastic differential game in continuous time that represents the unique viscosity solution to a terminal value problem for a parabolic partial differential equation involving the normalized $p(x,t)$-Laplace operator. Our game is formulated in a way that covers the full range $1<p(x,t)<\infty$. Furthermore, we prove the uniqueness of viscosity solutions to our equation in the whole space under suitable assumptions.

Minority Languages and Markets

2018

This chapter explores how minority languages figure in economic development and are invested with values of expertise, distinction and authenticity. Drawing on previous research, including the authors’ own studies on minority and indigenous language practices and discourses in peripheral, multilingual Irish and Sami sites, the chapter discusses the changing and expanding role of minority languages in some key economic domains: advertising and marketing, tourism, the media and job markets. It reflects on the conditions and consequences of economic processes for the exchange value of minority languages in changing markets.

A posteriori error majorants of the modeling errors for elliptic homogenization problems

2013

In this paper, we derive new two-sided a posteriori estimates of the modeling errors for linear elliptic boundary value problems with periodic coefficients solved by homogenization. Our approach is based on the concept of functional a posteriori error estimation. The estimates are obtained for the energy norm and use solely the global flux of the non-oscillatory solution of the homogenized model and solution of a boundary value problem on the cell of periodicity.

High Biological Value Compounds Extraction from Citrus Waste with Non-Conventional Methods.

2020

Citrus fruits are extensively grown and much consumed around the world. Eighteen percent of total citrus cultivars are destined for industrial processes, and as a consequence, large amounts of waste are generated. Citrus waste is a potential source of high biological value compounds, which can be used in the food, pharmaceutical, and cosmetic industries but whose final disposal may pose a problem due to economic and environmental factors. At the same time, the emerging need to reduce the environmental impact of citrus waste and its responsible management has increased. For these reasons, the study of the use of non-conventional methods to extract high biological value compounds such as caro…

On singular integral and martingale transforms

2007

Linear equivalences of norms of vector-valued singular integral operators and vector-valued martingale transforms are studied. In particular, it is shown that the UMD(p)-constant of a Banach space X equals the norm of the real (or the imaginary) part of the Beurling-Ahlfors singular integral operator, acting on the X-valued L^p-space on the plane. Moreover, replacing equality by a linear equivalence, this is found to be the typical property of even multipliers. A corresponding result for odd multipliers and the Hilbert transform is given.

From Feynman–Kac formulae to numerical stochastic homogenization in electrical impedance tomography

2016

In this paper, we use the theory of symmetric Dirichlet forms to derive Feynman–Kac formulae for the forward problem of electrical impedance tomography with possibly anisotropic, merely measurable conductivities corresponding to different electrode models on bounded Lipschitz domains. Subsequently, we employ these Feynman–Kac formulae to rigorously justify stochastic homogenization in the case of a stochastic boundary value problem arising from an inverse anomaly detection problem. Motivated by this theoretical result, we prove an estimate for the speed of convergence of the projected mean-square displacement of the underlying process which may serve as the theoretical foundation for the de…

Un cuento de robots : La hija cibernética de descartes

2021

French philosopher René Descartes is today valued as a forerunner of the studies of human mind, artificial intelligence and robotic systems. Throughout his work there are large references to automata and the possibility of artificial life, as well as an assessment of the differences between rational behavior of human beings and the purely mechanical of animals and automata. In addition to these references, there is a fable about the creation by the philosopher of an automaton that replicated his deceased daughter Francine, a story that is well known among the French and Anglo-Saxon specialists, but not so much in the Spanish ones, which is what settles this short work
