L'histoire des politiques culturelles des villes
1997
The history of cities' cultural policies, Philippe Poivrier. At the crossroads of the renewal of political history and cultural history, a new research area has been open to historians after a heavy occupation of the land by sociologists and political scientists. The article goes into the methodological stakes that accompany the examination of this public treatment of culture. A new approach of the social stakes of our societies could take effect, by giving to contemporary history a goal that has not been very much in evidence until now: the well-argued study of locality.
Moving Localities and Creative Circulation: Travels as Knowledge Production in 18th-Century Europe
2014
In recent historiography of science, circulation has been widely used to weave global narratives about the history of science. These have tended to focus on flows of people, objects and practices rather than investigating the spread of universal patterns of knowledge. The approach has also, to a great extent, concentrated on colonial contexts and treated ‘European science’ as a more or less homogeneous knowledge realm. Furthermore, these studies of circulation have usually been tied to a contextualist view of knowledge formation in which locality is taken as a set of specificities linked with particular locations. In this article we redirect the focus of the discussion on circulation to Eur…
Redescription of Tipula octomaculata Savchenko, with notes on related Holarctic species (Diptera, Tipulidae)
2007
Tipula (Pterelachisus) octomaculata Savchenko, 1964 (Diptera, Tipulidae) has hitherto been known only from the type locality in north-western Russia, and no material besides the holotype male has been available for study. In this article we report T. octomaculata for the first time from Finland, redescribe the species and compare its morphological characters with those of related Nearctic species (T. trivittata Say, T. angulata Loew, T. entomophthorae Alexander). The Finnish finding locality in Ks: Taivalkoski, North boreal ecoregion, is briefly discussed.
DECAY OF NONLOCALITY DUE TO ADIABATIC AND QUANTUM NOISE IN THE SOLID STATE
2010
We study the decay of quantum nonlocality, identified by the violation of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality, for two noninteracting Josephson qubits subject to independent baths with broadband spectra typical of solid state nanodevices. The bath noise can be separated in an adiabatic (low-frequency) and in a quantum (high-frequency) part. We point out the qualitative different effects on quantum nonlocal correlations induced by adiabatic and quantum noise. A quantitaive analysis is performed for typical noise figures in Josephson systems. Finally we compare, for this system, the dynamics of nonlocal correlations and of entanglement.
Large Scale Knowledge Matching with Balanced Efficiency-Effectiveness Using LSH Forest
2017
Evolving Knowledge Ecosystems were proposed to approach the Big Data challenge, following the hypothesis that knowledge evolves in a way similar to biological systems. Therefore, the inner working of the knowledge ecosystem can be spotted from natural evolution. An evolving knowledge ecosystem consists of Knowledge Organisms, which form a representation of the knowledge, and the environment in which they reside. The environment consists of contexts, which are composed of so-called knowledge tokens. These tokens are ontological fragments extracted from information tokens, in turn, which originate from the streams of information flowing into the ecosystem. In this article we investigate the u…
Locality-Sensitive Hashing for Massive String-Based Ontology Matching
2014
This paper reports initial research results related to the use of locality-sensitive hashing (LSH) for string-based matching of big ontologies. Two ways of transforming the matching problem into a LSH problem are proposed and experimental results are reported. The performed experiments show that using LSH for ontology matching could lead to a very fast matching process. The quality of the alignment achieved in these experiments is comparable to state-of-the-art matchers, but much faster. Further research is needed to find out whether the use of different metrics or specific hardware would improve the results. peerReviewed
A thermodynamics-based formulation of gradient-dependent plasticity
1998
Abstract A nonlocal thermodynamic theoretical framework is provided as a basis for a consistent formulation of gradient-dependent plasticity in which a scalar internal variable measuring the material isotropic hardening/softening state is the only nonlocal variable. The main concepts of this formulation are: i) the ‘regularization operator’, of differential nature, which governs the relation between the above nonlocal variable and a related local variable (scalar measure of plastic strain) and confers a unified character to the proposed formulation (this transforms into a formulation for nonlocal plasticity if the regularization operator has an integral nature); ii) the ‘nonlocality residua…
First record of Synedropsis roundii (Bacillariophyta, Fragilariaceae) in the Mediterranean region
2019
Populations of the fragilarioid diatom Synedropsis roundii are described from the phytoplankton of the Albufera of Valencia, a large and shallow eutrophic lagoon in the Spanish Mediterranean coast. The specimens collected are described and illustrated with light and scanning electron microscopy. This is the first documented record of this species since its description, and the first illustrated record of the genus in the Mediterranean region. The Albufera lagoon and the type locality of the species (Imboassica Lagoon, SE Brazil) are similar in some ecological features. The ecological and biogeographical implications of this finding are briefly discussed.
Joint reality and Bell inequalities for consecutive measurements
2006
Some new Bell inequalities for consecutive measurements are deduced under joint realism assumption, using some perfect correlation property. No locality condition is needed. When the measured system is a macroscopic system, joint realism assumption substitutes the non-invasive hypothesis advantageously, provided that the system satisfies the perfect correlation property. The new inequalities are violated quantically. This violation can be expected to be more severe than in the case of precedent temporal Bell inequalities. Some microscopic and mesoscopic situations, in which the new inequalities could be tested, are roughly considered.
DNA multigene sequencing of topotypic specimens of the fascioliasis vector Lymnaea diaphana and phylogenetic analysis of the genus Pectinidens (Gastr…
2012
Freshwater lymnaeid snails are crucial in defining transmission and epidemiology of fascioliasis. In South America, human endemic areas are related to high altitudes in Andean regions. The species Lymnaea diaphana has, however, been involved in low altitude areas of Chile, Argentina and Peru where human infection also occurs. Complete nuclear ribosomal DNA 18S, internal transcribed spacer (ITS)-2 and ITS-1 and fragments of mitochondrial DNA 16S and cytochrome c oxidase (cox)1 genes of L. diaphana specimens from its type locality offered 1,848, 495, 520, 424 and 672 bp long sequences. Comparisons with New and Old World Galba/Fossaria, Palaearctic stagnicolines, Nearctic stagnicolines, Old Wo…
