The relevance of point defects in studying silica-based materials from bulk to nanosystems
2019
The macroscopic properties of silica can be modified by the presence of local microscopic modifications at the scale of the basic molecular units (point defects). Such defects can be generated during the production of glass, devices, or by the environments where the latter have to operate, impacting on the devices’ performance. For these reasons, the identification of defects, their generation processes, and the knowledge of their electrical and optical features are relevant for microelectronics and optoelectronics. The aim of this manuscript is to report some examples of how defects can be generated, how they can impact device performance, and how a defect species or a physical phenomenon …

Optimal Spectral Wavelengths for Discriminating Orchard Species Using Multivariate Statistical Techniques
2019
Sustainable management of orchard fields requires detailed information about the tree types, which is a main component of precision agriculture programs. To this end, hyperspectral imagery can play a major role in orchard tree species mapping. Efficient use of hyperspectral data in combination with field measurements requires the development of optimized band selection strategies to separate tree species. In this study, field spectroscopy (350 to 2500 nm) was performed through scanning 165 spectral leaf samples of dominant orchard tree species (almond, walnut, and grape) in Chaharmahal va Bakhtiyari province, Iran. Two multivariable methods were employed to identify the optimum wavelengths:…
Magny-sur-Tille (Côte-d’Or). 9 rue du Château [notice archéologique]
2019
L’opération de diagnostic archéologique « 9, rue du Château » à Magny-sur-Tille s’est déroulée du 12 au 14 février 2018. La principale occupation détectée lors de l’opération consiste en une maison forte de la période moderne, déjà largement documentée par les sources écrites et planimétriques anciennes ainsi que par un diagnostic réalisé en 2007 avant la construction d’une maison individuelle. Le quart SO de l’établissement a été appréhendé. Trois phases ont pu être mises en évidence.
Assouad Type Dimensions in Geometric Analysis
2021
We consider applications of the dual pair of the (upper) Assouad dimension and the lower (Assouad) dimension in analysis. We relate these notions to other dimensional conditions such as a Hausdorff content density condition and an integrability condition for the distance function. The latter condition leads to a characterization of the Muckenhoupt Ap properties of distance functions in terms of the (upper) Assouad dimension. It is also possible to give natural formulations for the validity of Hardy–Sobolev inequalities using these dual Assouad dimensions, and this helps to understand the previously observed dual nature of certain cases of these inequalities. peerReviewed
GPU-accelerated time integration of Gross-Pitaevskii equation with discrete exterior calculus
2022
The quantized vortices in superfluids are modeled by the Gross-Pitaevskii equation whose numerical time integration is instrumental in the physics studies of such systems. In this paper, we present a reliable numerical method and its efficient GPU-accelerated implementation for the time integration of the three-dimensional Gross-Pitaevskii equation. The method is based on discrete exterior calculus which allows us the usage of more versatile spatial discretization than traditional finite difference and spectral methods are applicable to. We discretize the problem using six different natural crystal structures and observe the correct choices of spatial tiling to decrease the truncation error…
Paattisesta vieraasta sanottuun ja omaan sovitettuun vieraaseen : tutkielma vieraan käsitteestä Bernhard Waldenfelsin filosofiassa
2012
Tutkielman aiheena on vieraan (das Fremde) käsite Bernhard Waldenfelsin filosofiassa. Nykyfilosofian piirissä erilaiset vierauteen ja toiseuteen liittyvät kysymykset näyttäisivät nousevan aina vain keskeisempään osaan aikakautemme akateemisissa diskursseissa. Tätä temaattista tendenssiä ovat vauhdittaneet muun muassa ilmiöt, joiden yhteydessä on alettu käyttää termiä ’globaali’ sekä erilaisilla elämänalueilla lisääntyneet kulttuurien väliset kohtaamiset. Waldenfels on tuonut vieraus- ja toiseusdiskursseihin uusia merkittäviä piirteitä, jotka ovat vielä suhteellisen tuntemattomia. Waldenfelsin filosofiaa voidaan pitää kuitenkin melko vaikeasti ymmärrettävänä, varsinkin jos tulkitsija ei omaa…
El cumplimiento de la obligación
2020
The book deals with the Italian discipline of the performance of the obligation in a dogmatic and comparative key. The analysis addresses the identification of the notion of performance in the light of the correct conceptualization of the object of the obligation. Specific attention is then dedicated to the performance of ex contract obligations and to the problem of events fundamentally alters the equilibrium of the contract.

Low Tree Vigor, Free Palmette Training Form, and High Planting Density Increase Olive and Oil Yield Efficiency in Dry, Sloping Areas of Mediterranean…
2022
Exploiting biodiversity must be considered today an effective strategy to improve the sustainability of olive production systems. The evaluation of local cultivars, based on their vegetative and fruiting traits, along with an analysis of product quality, may contribute significantly to the development and diffusion of new olive-growing systems. The aim of this study was to evaluate growth, productivity, and olive oil quality of three Sicilian cultivars with different vigor/growth habit grown in four different combinations of training form and planting density. ‘Abunara’, ‘Calatina’, and ‘Nocellara del Belice’ olive trees were planted in four different int…
