Bi-2212 and Y123 highly curved single-crystal-like objects: whiskers, bows and ring-like structures
2012
High-temperature superconducting objects of Bi2Sr2CaCu2O8 and Y Ba2Cu3O7 highly curved in the ab-plane, such as curved/kinked whiskers, bows and ring-like structures, were obtained within a solid?liquid?solid (SLS) grass-like growth mechanism. As-grown objects are crystals with three-dimensional epitaxy similar to conventional single crystals: they can be viewed as crystal parts ?cut? from a conventional rectangular crystal. Between our curved objects and conventional crystals, whiskers or thin films there are some differences in the superconducting properties induced only by the shape factors and no new physics is observed. Some details of the growth mechanism are discussed, emphasizing cu…
Universal Restrictions in Reading: What Do French Beginning Readers (Mis)perceive?
2020
International audience; Despite the many reports that consider statistical distribution to be vitally important in visual identification tasks in children, some recent studies suggest that children do not always rely on statistical properties to help them locate syllable boundaries. Indeed, sonority-a universal phonological element-might be a reliable source for syllable segmentation. More specifically, are children sensitive to a universal phonological sonority-based markedness continuum within the syllable boundaries for segmentation (e.g., from marked, illegal intervocalic clusters, "jr," to unmarked, legal intervocalic clusters, "rj"), and how does this sensitivity progress with reading…
Which status for sensoric based discourses on digital social networks? Methodological reflections based on a corpus of wine descriptions in French an…
2019
International audience; [Context] The rise of digital humanities, embracing the expansion of digital speech production of western societies, imposes to reconsider the status of textual data – especially for specialized discourses (Lerat 1995, Petit 2010), for which written discourse has always been the most analyzed form of language use. Siever (2015: 85-86) has already raised the issue of the very nature of digital discourses in terms of medium, such as defined alongside the traditional oral-written-continuum (Koch & Oesterreicher 1994: 528). This led to a necessary theoretical and methodological shift giving priority to the conceptual level as embodied in the distance-proximity paradigm (…

The matrix metalloproteinase and insulin-like growth factor system in oral cancer : a prospective clinical study
2017
Aim The absence of reliable single serum biomarkers for oral premalignant lesion (OPL) and oral squamous cell carcinoma (OSCC) limits early diagnosis, monitoring of advanced disease, and prediction of prognosis. Methods In this prospective study, serum levels of matrix metalloproteinase (MMP)-2, MMP-3, MMP-13, insulin-like growth factor (IGF)-1, and IGF-binding protein (IGFBP)-3 were measured in 81 untreated OSCC patients, 49 healthy subjects, and 75 individuals with OPLs, and correlated with clinicopathological parameters. Results Serum levels of MMP-3 were significantly higher in OSCC patients compared to healthy subjects (p=0.004). Mean IGF-1 and IGFBP-3 levels in OSCC patients were sign…

Conception de documents numériques : Parcours méthodologique
2009
There is a strong social demand for studies of digital document. Yet our models of society and education are struggling to integrate issues related to these types of documents. However, the subject is less than half a century old, and so it is hardly surprising that the writing and training practices are just being developed. Like the book, the digital document involves many different skills and techniques in its development. The list of jobs tends to grow steadily: ergonomists, referencing specialists, information architects, programmers, designers, integrators ... It is therefore difficult to have a global view on all this know-how and the related methodologies. This special edition seeks…
Définir la structure de navigation : quelques outils méthodologiques
2008
On peut distinguer deux niveaux de structuration des documents numériques. Ces deux niveaux correspondent aussi à deux niveaux de découpage de l'information. le niveau «macro» correspond au découpage de l'information d'un domaine en différentes unités d'informations (écrans). Le niveau inférieur, ou « micro » correspond au découpage de l'information en concept sur chaque écran. Par « macro structuration », on entend donc la structuration du document qui n'est pas forcément visible par l'utilisateur mais qui est perceptible lors des déplacements en son sein. L'objectif de cette structuration est de proposer une arborescence, qui corresponde à l'objet du document numérique. Deux principaux ob…
Etude de l'impact du contrôle postural associé au port de verres prismatiques dans la réduction des troubles cognitifs chez le dyslexique de développ…
2007
But de l’etude L’objectif de ce travail est d’evaluer l’impact des modifications proprioceptives induites par un traitement postural sur les troubles cognitifs d’une population d’enfants souffrant de dyslexie de developpement. Patients et methodes Il a ete constitue un groupe de 20 enfants dyslexiques traites par prismes posturaux, semelles « de posture » et reeducation posturale, et un groupe temoin de 13 enfants dyslexiques portant uniquement des lunettes sans prismes. Tous les enfants etaient de sexe masculin. Lors de leur inclusion dans l’etude (M0) et 6 mois plus tard (M6), tous les participants ont ete evalues par un bilan ophtalmologique et postural et ont recu un examen neuropsychol…
Minerality in wines: mental expectations of Swiss and French consumers
2014
Today the concept of minerality in wines is omnipresent. It appears in marketing discourses, in oenological critics and commercial communication. However, there is no common agreement on a general definition. This paper aims to study the different expectations that Swiss and French consumers have about minerality. The multidimensionality of the term is reflected through stereotypes like the odor of flint, the impression of "sucking a stone", or referring to acidity or to the Terroir. Thus, the term minerality appears as a unstable concept and providing a precise definition remains consequently difficult for many consumers.
