3T Double Inversion Recovery Magnetic Resonance Imaging: diagnostic advantages in the evaluation of cortical development anomalies
2016
Abstract Purpose The aim of this work was to investigate the diagnostic value of the DIR sequence at 3T MR imaging operating in the evaluation of cortical development anomalies. Methods We studied 40 patients, with a previous diagnosis of cortical dysplasia, by FLAIR-3D, DIR, FSE T2 and MPR-GE T1 sequences at 3T MRI. Two independent observers evaluated, for each sequence and lesion, some semiological aspects (cortical thickness, cortical signal intensity, white-gray matter blurring, subcortical white matter intensity). We made also a quantitative evaluation of the cortical signal intensity in lesion site, drawing a ROI on each MRI sequences and comparing them to the correspondent normal con…
Andrew Taylor: Australia’s Poet of the (Extra)Ordinary
2019
Andrew Taylor (1940-) has been regarded as one of the most significant living Australian poets largely due to the fact of his unusual use of the poetic language and the selection of topics. He undoubtedly belongs to the group of the poets, like John Kinsella, who create mastery in their so-called ‘niche’ market, quietly continuing to produce compositions of remarkable quality, and receiving national and international recognition for their achievements. Andrew Taylor’s Impossible Preludes (Poems 2008-2014) is a unique and beautiful retrospective on life, love and everything in between, with its full array of extraordinariness embedded in the ordinariness of everyday life. Each line is a stor…
El concepte de malaltia en la constitució de l'antropologia cultural
1995
Aquest assaig tracta d'estudiar una correlació, potser una mica innovadora, entre els conceptes de 'malaltia' i 'cultura' en el procés de constitució del discurs antropològic anomenat científic, un discurs que aconseguí un lloc reconegut en el món acadèmic i dels museus sota el paradigma d'estudi que avui solem anomenar l'evolucionisme clàssic.
On the use of fractional calculus for the probabilistic characterization of random variables
2009
In this paper, the classical problem of the probabilistic characterization of a random variable is re-examined. A random variable is usually described by the probability density function (PDF) or by its Fourier transform, namely the characteristic function (CF). The CF can be further expressed by a Taylor series involving the moments of the random variable. However, in some circumstances, the moments do not exist and the Taylor expansion of the CF is useless. This happens for example in the case of $\alpha$--stable random variables. Here, the problem of representing the CF or the PDF of random variables (r.vs) is examined by introducing fractional calculus. Two very remarkable results are o…
Karl-Otto Apel’s discourse ethics in dialogue with Charles Taylor’s hermeneutical ethics
2019
El objetivo de este trabajo es poner de manifiesto la relevancia del legado filosófico de Karl-Otto Apel a la luz del diálogo con la ética de Charles Taylor. Nos detenemos en los últimos libros publicados de Charles Taylor y ensayamos una interpretación crítica de sus tesis a partir de la pragmática trascendental de Apel. Hundiendo sus raíces en la matriz hermenéutica y crítica, la ética del discurso de Karl-Otto Apel sigue ofreciendo una dialéctica fecunda entre realidad e idealidad que resulta insoslayable para afrontar con garantías el futuro de la humanidad. The aim of this paper is to highlight the relevance of the philosophical legacy of Karl-Otto Apel in light of the dialogue with th…
Fractional Spectral Moments for Digital Simulation of Multivariate Wind Velocity Fields
2012
In this paper, a method for the digital simulation of wind velocity fields by Fractional Spectral Moment function is proposed. It is shown that by constructing a digital filter whose coefficients are the fractional spectral moments, it is possible to simulate samples of the target process as superposition of Riesz fractional derivatives of a Gaussian white noise processes. The key of this simulation technique is the generalized Taylor expansion proposed by the authors. The method is extended to multivariate processes and practical issues on the implementation of the method are reported.

On the fractional probabilistic Taylor's and mean value theorems
2016
In order to develop certain fractional probabilistic analogues of Taylor's theorem and mean value theorem, we introduce the nth-order fractional equilibrium distribution in terms of the Weyl fractional integral and investigate its main properties. Specifically, we show a characterization result by which the nth-order fractional equilibrium distribution is identical to the starting distribution if and only if it is exponential. The nth-order fractional equilibrium density is then used to prove a fractional probabilistic Taylor's theorem based on derivatives of Riemann-Liouville type. A fractional analogue of the probabilistic mean value theorem is thus developed for pairs of nonnegative rand…
La perspectiva intercultural. Ortega y la hermenéutica
2018
En este artículo presento la perspectiva intercultural a partir de la doctrina orteguiana del punto de vista. Aunque Ortega no emplea en sus escritos el término “intercultural”, expongo de qué modo es posible entender su perspectivismo en términos interculturales. Para ello además de conectarlo con los planteamientos de dos de los principales autores de la tradición hermenéutica como son Hans-Georg Gadamer y Charles Taylor, destaco la dimensión intercultural de su perspectivismo. A lo largo del artículo critico posturas deficientes como son el relativismo, el etnocentrismo, el positivismo, el culturalismo y la beatería de la cultura. In this article, I present the intercultural perspective …
A representation of wind velocity by means of fractional spectral moments
2009
This paper deals with the definition of a new function that is a link between Power Spectral Density (PSD) and correlation function, called the Fractional Spectral Moments function. This is defined as the moment of complex order g of the one-sided PSD. It is shown that by means of this complex function both the correlation function and PSD can be represented with great accuracy.
