La forme des villes françaises est-elle déterminée par les morphologies bâties et non bâties qui les environnent ? Éléments de réponse apportés par d…

2016

International audience; Des chercheurs en géographie ont montré, depuis les années 90, que les villes contemporaines partagent les caractéristiques morphologiques de certains objets fractals : les bordures urbaines sont très indentées à travers les échelles ; dans chaque ville, le nombre d’agrégats bâti et leur taille suivent une loi de puissance tandis que le nombre d’espaces non bâtis est relié à leur taille selon une autre loi de puissance (Batty & Longley, 1994 ; Frankhauser, 1994). Les dimensions fractales permettent de caractériser au moyen de mesures quantitatives les formes urbaines et ainsi de comparer aussi bien des villes entre elles que des quartiers d’une ville.Nous proposons i…

Natural and anthropogenic sources of total suspended particulate and their contribution to the formation of black crusts on building stone materials …

2012

Blackening and disaggregation of exposed surfaces of stone monuments are well-known effects of stone decay taking place in polluted urban environments all over the world. This paper aims to assess the contribution of natural and anthropogenic sources of total suspended particulate (TSP) causing permanent damage (black crusts) to the stone monuments of Catania (Sicily), one of the most popular ‘‘cities of art’’ of southern Italy. Atmospheric pollution of Catania, a typical Mediterranean coastal town, is mainly contributed by vehicle exhaust emissions rather than industrial ones. Episodically, the city also suffers gaseous and ash emissions (plumes) from the nearby Mount Etna volcano. Thus, t…

Worldwide production on sleep apnea from 2009–2018. Analysis of the ability to secure funding and international collaboration networks

2021

[Background]: Obstructive sleep apnea (OSA) is an emerging health problem, but information on scientific production in this subject area is scarce. We aim to evaluate the scientific production on OSA from 2009 to 2018 to illustrate its worldwide distribution, topic areas, and ability to secure funding, as well as to describe international collaboration networks in this field. [Methods]: Articles published between 2009 and 2018 were extracted from the Science Citation Index Expanded via Web of Science (WoS) using the search term “obstructive sleep apn*“. Publication year, number and country of authors, journal, subject category, key words, funding source and number of citations received were…

Endosperm cintribution to Medicago truncatula seed development : characterization of a DOF transcription factor expressed in chalazal endosperm

2014

In the current context, which necessitates a reduction in inputs in crop systems and boosting of production of plant proteins to reduce France’s dependency on feed imports,, growing legumes represents an alternative. Grain legumes are major sources of proteins for animal and human nutrition. In the UMR1347 Agroécologie, the objectives of the study group "déterminismes Génétiques et Environnementaux de l’Adaptation des Plantes à des Systèmes de culture Innovants" (GEAPSI) are to promote legume cultivation and adaptation to environmental stresses, via multidisciplinary approaches (genetics, ecophysiology, molecular physiology). This thesis project was carried out in the "Étude des Mécanismes …

Using Tsetlin Machine to discover interpretable rules in natural language processing applications

2021

Tsetlin Machines (TM) use finite state machines for learning and propositional logic to represent patterns. The resulting pattern recognition approach captures information in the form of conjunctive clauses, thus facilitating human interpretation. In this work, we propose a TM-based approach to three common natural language processing (NLP) tasks, namely, sentiment analysis, semantic relation categorization and identifying entities in multi-turn dialogues. By performing frequent itemset mining on the TM-produced patterns, we show that we can obtain a global and a local interpretation of the learning, one that mimics existing rule-sets or lexicons. Further, we also establish that our TM base…

VirDe: A new virtual reality design approach

2008

Virtual reality (VR), even if it does not represent any more a novel technology, is one of the most powerful tool to help designers during the development of new projects. This is proved by very numerous research activities related to this field. In this research, we have studied a new way to approach the development of a product. We present the ongoing development of a system, called VirDe, acronym of virtual design, which can allow the designers to perform the whole design process, from the modelling phase to the finite element method (FEM) simulation analysis, in a virtual reality environment. This new method allows remarkable time and money saving in the overall product design process, …

MOLECULAR ANALYSIS OF COLLETOTRICHUM SPECIES ASSOCIATED TO OLIVE IN CALABRIA.

2013

A new molecular approach based on the use of genus-specific primers targeting the internal transcribed spacer (ITS) regions of rDNA, was developed and used to study the diversity of Colletotrichum species associated with the olive canopy in the Gioia Tauro plain (Calabria, southern Italy). Representative symptomatic and symptomless samples of leaves, flowers and fruits were collected during 2012 and analyzed by extracting total DNA and amplifying the target region with the genus-specific primers. Amplicons were cloned and sequenced in order to use the ITS as a barcode gene. No Colletotrichum species were detected in the first sampling period (May 28, 2012), whereas around 15% of the analyze…
