Produire expérimentalement des corpus spécialisés pour l’analyse sémantique : méthodes et enjeux
2018
International audience; [Contexte] La présente proposition vise, à la suite de De Mönnink (1999) et Gilquin / Gries (2009), à interroger et discuter le rôle de corpus produits expérimentalement et de façon ad hoc pour l’analyse du lexique spécialisé – que les unités considérées soient officiellement reconnues comme termes ou non. Elle s’inscrit dans le paradigme d’une recherche située (Condamines / Narcy-Combes 2015) et intrinsèquement interdisciplinaire (Gautier 2014). Si les corpus spécialisés écrits, et dans une moindre mesure oraux, sont devenus monnaie courante, qu’ils soient intégrés aux corpus de référence ou produits pour des besoins spécifiques (Loock 2016), les corpus expérimentau…
Cortical gene expression in spinal cord injury and repair: insight into the functional complexity of the neural regeneration program
2011
Traumatic spinal cord injury (SCI) results in the formation of a fibrous scar acting as a growth barrier for regenerating axons at the lesion site. We have previously shown (Klapka et al., 2005) that transient suppression of the inhibitory lesion scar in rat spinal cord leads to long distance axon regeneration, retrograde rescue of axotomized cortical motoneurons, and improvement of locomotor function. Here we applied a systemic approach to investigate for the first time specific and dynamic alterations in the cortical gene expression profile following both thoracic SCI and regeneration-promoting anti-scarring treatment (AST). In order to monitor cortical gene expression we carried out micr…
Counterbalancing salt reduction with aromas and consequences on sensory acceptability: A study with real cheese
2014
Introduction and objective: Unbalanced diet with an overconsumption of salt contributes to the development of cardiovascular disease. Several strategies are currently investigated to design low-salt food while maintaining taste and consumer liking. The strategy relying on cross-modal sensory compensation is being tested within the framework of the EU-TeRiFiQ research project. In this context, this study had for aim to examine whether selected aromas could help to maintain salt and fat perception in low-salt real cheese. Methods: Two commercial cheeses, low-salt cheese (LSC) and regular-salt cheese (RSC), were reprocessed by grinding and addition of a sardine aroma associated to salty taste …

Rôle des enzymes du métabolisme des xénobiotiques dans la perception de la caféine chez la drosophile
2010
National audience; Les animaux ont développé des systèmes de communication avec leur environnement indispensables à leur survie et leur reproduction. Les systèmes chimiosensoriels gustatifs et olfactifs détectent et transmettent au niveau central les informations chimiques de l’environnement (xénobiotique) afin que l’individu distingue les sources alimentaires des substances toxiques et reconnaisse ses proies de ses congénères. Ces systèmes, pour être efficaces, doivent être très sensibles et discriminants, et éviter la saturation des récepteurs. Dans l’espace péri-récepteur, les enzymes du métabolisme des xénobiotiques (EMX), impliquées normalement dans la détoxication, pourraient égalemen…

UAV-Assisted Data Collection in Wireless Sensor Networks: A Comprehensive Survey
2021
Wireless sensor networks (WSNs) are usually deployed to different areas of interest to sense phenomena, process sensed data, and take actions accordingly. The networks are integrated with many advanced technologies to be able to fulfill their tasks that is becoming more and more complicated. These networks tend to connect to multimedia networks and to process huge data over long distances. Due to the limited resources of static sensor nodes, WSNs need to cooperate with mobile robots such as unmanned ground vehicles (UGVs), or unmanned aerial vehicles (UAVs) in their developments. The mobile devices show their maneuverability, computational and energy-storage abilities to support WSNs in mul…
Data Compensation with Gaussian Processes Regression: Application in Smart Building's Sensor Network
2022
Data play an essential role in the optimal control of smart buildings’ operation, especially in building energy-management for the target of nearly zero buildings. The building monitoring system is in charge of collecting and managing building data. However, device imperfections and failures of the monitoring system are likely to produce low-quality data, such as data loss and inconsistent data, which then seriously affect the control quality of the buildings. This paper proposes a new approach based on Gaussian process regression for data-quality monitoring and sensor network data compensation in smart buildings. The proposed method is proven to effectively detect and compensate for low-qu…
Monitoring water and carbon fluxes at fine spatial scales using HyspIRI-like measurements
2012
Remotely sensed observations in the visible to the shortwave infrared (VSWIR) and thermal infrared (TIR) regions of the electromagnetic spectrum can be used synergistically to provide valuable products of land surface properties for reliable assessments of carbon and water fluxes. The high spatial, spectral and temporal resolution VSWIR and TIR observations provided by the proposed Hyperspectral - InfraRed (HyspIRI) mission will enable a new era of global agricultural monitoring, critical for addressing growing issues of food insecurity. To enable predictions at fine spatial resolution (<100m), modeling efforts must rely on a combination of high-frequency temporal and highresolution spa…
IDS sistēmas ieviešana augstas veiktspējas tīklu drošības monitoringam ar atvērtā pirmkoda rīkiem un patēriņa aparatūru
2019
Darba mērķis ir izpētīt, kā izmantot atvērtā pirmkoda IDS sistēmas ar patēriņa aparatūru, lai monitorētu drošību augstas veiktspējas tīklos, kuros tīkla caurlaidība pārsniedz 10Gbit/s. Lai parādītu, kāds ir veiktspējas ieguvums no dažādām ar veiktspēju saistītam izmaiņām IDS sistēmā, mērķis ir veikt sistēmas ieviešanu, kur tiek veiktas izmaiņas pa posmiem un tiek iegūti rezultāti par izmaiņām veiktspējas rādītājos. Darbā tika pētīti ar IDS sistēmas veiktspējas uzlabošanu saistīti akadēmiskie darbi, lai apkopotu tajās izmantotās metodes, kas ir palīdzējušas sasniegt augstus IDS sistēmas veiktspējas rādītājus.
