Differences in acoustically determined sentence stress between native and L2 speakers of Finland Swedish
2021
This study describes a pilot attempt to use acoustically determined sentence stress in distinguishing native and L2 speakers of Finland Swedish at different proficiency levels. The study is part of the DigiTala project that examines and develops automatic tools for spoken L2 assessment. Stressed syllables were detected in 235 L2 and 30 L1 speech samples using combinations of f0, intensity, and duration. Differences were found in the relative number of stressed syllables between native and L2 speakers using f0 and duration or all three features. Further research with more consistent speech data is needed to establish reliable automatic measures of sentence stress. nonPeerReviewed

How Wild Can It Get? Managing Language Learning Tasks in Real Life Service Encounters
2019
This chapter explores how experientially based pedagogical activities that involve participation in real life service encounters provide occasions for developing L2 interactional competence. The data comprises novice L2 students’ self-recorded interactions in service settings and videorecordings of classroom planning activities and de-briefing discussions, where the students reflect on their experiences. The analysis traces what kinds of occasions for learning arise as the students move between the classroom and the real-world service settings. The findings show that the different phases of the task complement each other in supporting the development of interactional competence. The prepara…
Skeleton-Based Multiview Reconstruction
2016
International audience; The advantage of skeleton-based 3D reconstruction is to completely generate a single 3D object from well chosen views. Having numerous views is necessary for a reliable reconstruction but projections of skeletons lead to different topologies. We reconstruct 3D objects with curved medial axis (whose topology is a tree) from the perspective skeletons on an arbitrary number of calibrated acquisitions. The main contribution is to estimate the 3D skeleton, from multiple images: its topology is chosen as the closest to those of the perspective skeletons on the set of images, which means that the number of topology changes to map the 3D skeleton topology to topologies on im…
Polyphenols Epigallocatechin Gallate and Resveratrol, and Polyphenol-Functionalized Nanoparticles Prevent Enterovirus Infection through Clustering an…
2021
To efficiently lower virus infectivity and combat virus epidemics or pandemics, it is important to discover broadly acting antivirals. Here, we investigated two naturally occurring polyphenols, Epigallocatechin gallate (EGCG) and Resveratrol (RES), and polyphenol-functionalized nanoparticles for their antiviral efficacy. Concentrations in the low micromolar range permanently inhibited the infectivity of high doses of enteroviruses (107 PFU/mL). Sucrose gradient separation of radiolabeled viruses, dynamic light scattering, transmission electron microscopic imaging and an in-house developed real-time fluorescence assay revealed that polyphenols prevented infection mainly through clustering of…
IDENTIFICATION AND QUANTIFICATION OF PHENOLIC COMPOUNDS FROM RED GRAPE POMACE
2018
The wine industry generates a great amount of waste every year, thus its valorization is of most importance. This study uses red, fermented pomace from Cabernet Sauvignon and Feteasca Neagra cultivars. The phenolic compounds were extracted using four different extractions and the content of total polyphenols was determined using a spectrophotometrical method. Several phenolic compounds were analyzed using an HPLC method. The Cabernet Sauvignon pomace had the highest content of total polyphenols and total phenolic compounds analyzed and of quercetin, rutin, ferulic acid and resveratrol, while the Feteasca Neagra pomace had the highest content of gallic acid, syringic acid, cinamic acid and (…

Les sarcophages mérovingiens en trachyte. Des carrières aux lieux d'enfouissement (Massif central)
2018
A multi-disciplinary team is currently working on trachyte, a volcanic rock from the Chaîne des Puys (French massif central), within a research program supported by the French ministry of Culture. Although it has been known at least since the 19th century that this rock was used for construction and sculpture in antiquity, and in the making of sarcophagi in the middle ages, the systematisation of the research on trachyte, carried out since 2008, has enabled us to make significant advances in the knowledge of its exploitation and dissemination. Geologists have established a detailed identity card of the six volcanoes where massive lava is available, thereby allowing the classification of eac…
Tractional Motion Machines extend GPAC-generable functions
2012
In late 17th century there appeared the Tractional Motion instruments, mechanical devices which plot the curves solving differential equations by the management of the tangent. In early 20th century Vannevar Bush’s Differential Analyzer got the same aim: in this paper we’ll compare the Differential Analyzer mathematical model (the Shannon’s General Purpose Analog Computer, or GPAC) with the Tractional Motion Machine potentials. Even if we will not arrive in defining the class of the functions generated by Tractional Motion Machines, we’ll see how this class will strictly extend the GPAC-generable functions.
Les poisons du XIXe et leur traduction à l’espagnol : Mateu Orfila et son Traité des poisons (1814-1815)
2019
Dans ce travail, on étudie une des œuvres pionnières de référence en toxicologie du XIXe siècle : Traité des poisons, publiée par Mathieu Orfila entre 1814 et1815 à Paris, traduite en espagnol par le Dr. Mariano de Larra y Langelot en 1819, et éditée à Madrid. Larra se vante, dans l'introduction, que sa traduction a été révisée par Orfila lui-même, détail qui n’apparaît pas dans les traductions en allemand, anglais ou italien. Nous présenterons les événements historiques qui ont accompagné cette première traduction, ainsi que les raisons qui ont conduit Mariano de Larra, père du célèbre écrivain romantique Mariano José de Larra, à traduire ce travail après avoir été exilé en France pendant …
