Extensible User-Based XML Grammar Matching
2009
International audience; XML grammar matching has found considerable interest recently due to the growing number of heterogeneous XML documents on the web and the increasing need to integrate, and consequently search and retrieve XML data originated from different data sources. In this paper, we provide an approach for automatic XML grammar matching and comparison aiming to minimize the amount of user effort required to perform the match task. We propose an open framework based on the concept of tree edit distance, integrating different matching criterions so as to capture XML grammar element semantic and syntactic similarities, cardinality and alternativeness constraints, as well as data-ty…
XCDL: an XML-oriented visual composition definition language
2010
International audience; XML data flow has reached beyond the world of computer science and has spread to other areas such as data communication, e-commerce and instant messaging. Therefore, manipulating this data by non expert programmers is becoming imperative. On one hand, Mashups have emerged a few years ago, providing users with visual tools for web data manipulation but not necessarily XML specific. Mashups have been leaning towards functional composition but no formal languages have yet been defined. On the other hand, visual languages for XML have been emerging since the standardization of XML, and mostly relying on querying XML data for extraction or structure transformations. These…
The hallmark of anonymity. Questions of authorship in the Hippocratic Corpus, specifically regarding the so-called 'Author C'
2020
Since Émile Littrés’ time a particular attention has been devoted to a group of Hippocratic treatises (On Generation/On the Nature of the Child + Book IV of Diseases) showing a significant range of affinities and common elements in language, style, tenor and thought. Studies by Hermann Grensemann (in the 1980s) contributed to further philological analysis of the peculiar traits of the so-called Hippocratic ‘author C’, widening the textual basis to be involved in the investigation (including gynaecological treatises like On Diseases of Women 1-2 as well as parts of Infertile Women). Recently new light has also been shed by Elizabeth Craik (editing 2009 the treatise On Glands) on the historic…
Artificial dam lakes as suitable habitats for exotic invertebrates: Ostracoda ecology and distribution in reservoirs of the Eastern Iberian Peninsula
2014
Reservoirs are the most common deep lakes in Spain, as a consequence of water needs and dry climate. Although these aquatic systems can play an important ecological role in such an area with few large natural lakes, they can also provide new habitats for exotic species, which can colonize ecosystems that native species have not explored yet. Here we present our results for a biannual survey of the ostracod fauna from 24 reservoirs in Xuquer River basin. We check which variables affect ostracod presence, test for differences between winter and summer assemblages, and compare our data with previous available ostracod records from the same river drainage network. Our results reveal that ostrac…
Infrastructures agroécologiques en droit
2017
International audience; Les infrastructures agroécologiques (IAE) sont une notion récente désignant des éléments naturels, culturels et paysagers, tels les mares, les landes, les haies, les talus, les fossés, les arbres, les bosquets, les bandes enherbées le long des cours d’eau, les murets de pierre ou encore les terrasses. Pendant des siècles, ces milieux physiques sont passés inaperçus pour le droit. Attachés au foncier, ils n’en constituaient qu’un accessoire sommé de suivre le régime juridique du principal. Ces infrastructures étaient sous l’entière maîtrise du propriétaire immobilier pouvant, à sa guise, les créer ou les faire disparaître. Leur statut a cependant c…
Droit et philosophie à la lumière de l'Encyclopédie
2015
International audience; Quelle place occupe le droit dans l’Encyclopédie de Diderot et de D’Alembert ? Quels rapports le mouvement encyclopédique et l’esprit de la Déclaration des droits de 1789 entretiennent-ils ? Dans cette étude novatrice, Luigi Delia explore les enjeux du droit dans l’entreprise emblématique des Lumières.Encadrée par la publication de deux ouvrages fondamentaux – L’Esprit des lois de Montesquieu (1748) et le Traité des délits et des peines de Beccaria (1765) –, l’Encyclopédie propose une nouvelle conception de la justice en faisant dialoguer des cultures juridiques différentes, celle des juristes et celle des philosophes. À partir …

Key advantages of the leverage points perspective to shape human-nature relations
2021
This perspective paper synthesises the special issue 'Human-nature connectedness as a leverage point for sustainability transformation'. Based on the articles in this special issue, we aim to foster the operationalisation of the leverage points perspective to shape human-nature relations to enable sustainability transformations. Specifically, we draw on four key advantages of the leverage points perspective: (i) the explicit recognition of deep leverage points; (ii) the ability to examine the interactions between shallow and deep system changes; (iii) the combination of causal and teleological modes of research; and (iv) the ability to function as a methodological boundary object. The contr…
Coscinolactams A and B: new nitrogen-containing sesterterpenoids from the marine sponge Coscinoderma mathewsi exerting anti-inflammatory properties
2009
Abstract Investigation of the marine sponge Coscinoderma mathewsi led to the isolation of two novel nitrogen-containing cheilanthane sesterterpenoids, coscinolactams A and B, together with known suvanine. The structures were elucidated by extensive spectroscopic measurements including NOE experiments to deduce the stereochemistry. The natural compounds, as well as a semisynthetic derivative, showed moderate anti-inflammatory activity measured as their capability to inhibit PGE2 and NO production. The suvanine aldehyde derivative 4 inhibited inducible nitric oxide protein expression with an IC50 value of 7.3 μM.
Ecological correlates of Golden Eagle Aquila chrysaetos breeding occurrence in Sardinia
2020
Capsule Golden Eagles Aquila chrysaetos in Sardinia are clustered across the main mountain ranges of the island, with a preference for undisturbed and homogeneous inland habitats. Aims To analyse habitat preferences of the Golden Eagle in Sardinia, Italy, at the landscape and home range spatial scales. Methods Landscape scale habitat preferences were analysed using the 10 × 10 km Universal Transverse Mercator grid and the home range scale was based on the spatial distribution of breeding territories. Generalized linear models were fitted with three different sets of environmental predictors (topographic, bioclimatic and land use variables) to analyse the spatial distribution of Golden Eagle…
