Article scientifique
L'épisode gélif que nous avons connu en ce début avril nous rappelle combien la météo peut impacter les cultures, notamment fruitières et viticoles. Un tel phénomène s'est également produit l'année dernière, en mai, alors que les vignes se trouvaient à un stade particulièrement sensible de leur développement. À cette occasion, le Carah a observé et analysé comment les différents cépages de son ...

[Disponible sur le site du sillon belge]La culture de maïs sous plastique soulève de nombreuses interrogations, notamment en matière d’environnement. Pour éclaircir cette problématique, le Carah a passé au crible différents types de plastique et a étudié plus précisément leur dégradabilité. Ces essais en laboratoire ont ensuite été complétés par une évaluation au champ, sous la houlette du Cipf. En ...
EEG dynamics and neural generators of psychological flow during one tightrope performance

Article scientifique
Psychological “flow” emerges from a goal requiring action, and a match between skills and challenge.
Using high-density electroencephalographic (EEG) recording, we quantified the neural generators characterizing psychological “flow” compared to a mindful “stress” state during a professional tightrope performance. Applying swLORETA based on self-reported mental states revealed the right superior ...

Non-invasive BMI applications are increasingly used in different contexts ranging from industrial, clinical and gaming. After having tested the difference between a classical EEG recorder with electroconductive gel (ANT system) and the MUSE EEG headband, we studied the BCI performances of the later during the control of a small robot. We demonstrated that the participants were able to successfully ...
Neural generators involved in visual cue processing in children with attention-deficit/hyperactivity disorder (ADHD)

Article scientifique
Event-related potentials (ERP) studies report alterations in the ongoing visuo-attentional processes in children with attention deficit/hyperactivity disorder (ADHD).
We hypothesized that the neural generators progressively recruited after a cue stimulus imply executive-related areas well before engagement in executive processing in children with ADHD compared to typically developed children (TDC)
Thorpe tube and oxygen flow restrictor : what's flow accuracy ?

Article scientifique
Oxygen gas flowmeters (OGF) are used to regulate the oxygen flow in acute and chronic care. In hospitals, Thorpe tubes (TT) are the classical systems most used for delivering oxygen. In recent years, the oxygen flow restrictor (OFR) has appeared. These devices use a series of calibrated openings in a disk that can be adjusted to deliver different flow rates. These devices have a reputation for ...
Cannabidiol in sport : Ergogenic or else ?

Article scientifique
In the sports domain, cannabis is prohibited by the World Anti-Doping Agency (WADA) across all sports in
competition since 2004. The few studies on physical exercise and cannabis focused on the main compound i.e.
Δ9-tetrahydrocannabinol. Cannabidiol (CBD) is another well-known phytocannabinoid present in dried or heated
preparations of cannabis. Unlike Δ9-tetrahydrocannabinol, CBD is non-intoxicating ...

We tested the ability of the self-organizing map (SOM), a type of artificial neural network, in revealing genetic patterns within the autotetraploid potato (Solanum tuberosum L.). A total of 591 potato varieties, originating from various main European breeder collections and released into different market segments between 1815 and 2015, were examined using a set of 21 informative microsatellite markers.
