Reformulation structures in French Belgian Sign Language (LSFB) > French interpreting:A pilot multimodal study
No full textThis article examines reformulation structures when interpreting French Belgian Sign Language (LSFB) into spoken French. Reformulation structures are defined as two segments of discourse, where the first segment conveys a message and the second segment, introduced by a marker, expresses the same message differently. By adopting a multimodal approach, interlingual reformulation structures (between the source and the target languages) and intralingual reformulation structures (within the target language) are described, focusing on their distribution, form, and semiotic composition. The dataset comprises dialogues produced by two LSFB signers and their interpretations into French by two LSFB–French interpreters. Interlingual and intralingual reformulation structures are present in French interpretations, although less frequently than in LSFB source dialogues. The most frequent forms of reformulation structures are found in both datasets. Interpreters do not seem to be influenced in their gesturing by the signs produced in the source LSFB dialogues. Still, they engage their hands, bodies, faces, and voices in their renditions. Hence, interpreters draw on all their available semiotic resources to convey meaning but differ from how source signers do it. In future research, the dataset should be enlarged and the type of manual gestures and nonmanual articulators used should be more closely investigated.</p
TapStrapGest: Elicitation and Recognition for Ring-based Multi-Finger Gestures:Elicitation and Recognition of Ring-based Multi-Finger Gestures
No full textWe introduce TapStrapGest, a novel solution for customizable ring-based multi-finger gestures, encompassing the process from gesture elicitation to gesture recognition. Recognizing the growing demand for intuitive and customizable gesture interaction with fingers, TapStrapGest uses Tap Strap to enable users to perform simple and complex multi-finger gestures using smart rings. We conducted a gesture elicitation study, detailing the systematic process of soliciting and refining a custom set of user-defined ring-based finger gestures through participatory design and ergonomic considerations, including thinking time, goodness of fit, and memorization. Subsequently, we delve into the technical underpinnings of gesture recognition. We reduce the dimensionality of a dataset of 27 gesture classes from 21 to 15 by filtering, then from 15 to 5 by a Principal Component Analysis. We implement and compare four machine learning algorithms to show that a Quadratic Discriminant Analysis (precision=99.33%, recall=99.26%, and F1-score=99.26%) outperforms three other machine learning classifiers, i.e., a Linear Discriminant Analysis, a Support Vector Machines, and a Random Forest, as well as existing recognizers from the literature, to accurately recognize such gestures without the need to call for Deep Learning. Through a performance analysis, we demonstrate that TapStrapGest is a versatile and admissible solution for ring-based multi-finger gesture interaction, opening avenues for "eyes-free" or "screen-free" human-computer interaction in various domains
Decoration of silver nanoparticles on WS2-WO3 nanosheets:Implications for surface-enhanced resonance Raman spectroscopy detection and material characteristics
Get PDFThis study investigates the chemical and structural modifications of vertically aligned tungsten disulfide–tungsten trioxide (WS2-WO3) nanosheets decorated with silver nanoparticles (Ag(NPs)) under nitrogen plasma conditions. The synthesized vertically aligned WS2-WO3 nanosheets were functionalized through direct-current (DC) magnetron sputtering, forming silver-decorated samples. Structural changes, as well as the size and distribution of Ag(NPs), were characterized using scanning electron microscopy (SEM). Chemical state analysis was conducted via X-ray photoelectron spectroscopy (XPS), while Raman spectroscopy was employed to investigate vibrational modes. The findings confirmed the successful decoration of Ag(NPs) and identified unexpected compound transformations that were dependent on the duration of functionalization. The synthesized and functionalized samples were evaluated for their sensing capabilities towards Rhodamine B (RhB) through surface-enhanced resonance Raman scattering (SERRS). This study discusses the impact of substrate morphology and the shape and size of nanoparticles on the enhancement of SERRS mechanisms, achieving an enhancement factor (EF) of approximately 1.6 × 106 and a limit of detection (LOD) of 10−9 M

No full textL’expansion du budget participatif:diversité des procédures, contexte municipal et moteurs électoraux dans le contexte belge
No full textLa participation du public est une notion plébiscitée de la gouvernance contemporaine. Le fonctionnement des mécanismes de participation a fait l’objet d’une analyse approfondie. L’étude systématique des raisons pour lesquelles certaines autorités publiques les mettent en œuvre est cependant peu étudiée. Cet article vise à combler cette lacune en se concentrant sur les processus de budget participatif (BP) dans le contexte belge (Wallonie et Bruxelles). Tout d’abord, nous analysons de façon critique le caractère « participatif » des BPs en comparant qui décide dans ces processus. Deuxièmement, nous identifions les facteurs contextuels et politiques qui favorisent la mise en place des BPs. Les résultats suggèrent que le recours au BP est devenu une pratique institutionnelle largement répandue et transcendant les orientations idéologiques des majorités locales. Cependant, la façon dont l’idéal participatif est mis en pratique révèle des dynamiques distinctes. Dans certains cas, l’utilisation de la rhétorique participative permet de requalifier une ancienne pratique, sans transformer la méthode d’allocation du budget de manière significative. Dans l’ensemble, cette étude cherche à offrir une meilleure compréhension de l’intégration des innovations démocratiques dans la gouvernance contemporaine

No full textNovel Insights into Emx2 and Dmrta2 Cooperation during Cortex Development and Evidence for Dmrta2 Function in the Choroid Plexus
No full textEarly dorsal telencephalon development is coordinated by an interplay of transcription factors that exhibit a graded expression pattern in neural progenitors. How they function together to orchestrate cortical development remains largely unknown. The Emx2 and Dmrta2 genes encode transcription factors that are expressed in a similar caudomedialhigh/rostrolaterallow gradient in the ventricular zone of the developing dorsal telencephalon with, in the medial pallium, Dmrta2 but not Emx2 expressed in the developing choroid plexus (ChP). Their constitutive loss has been shown to impart similar cortical abnormalities, and their combined deletion exacerbates the phenotypes, suggesting possible cooperation during cortex development. In this study, using embryos of both sexes, we utilized molecular and genetic approaches to dissect how Emx2 functions with Dmrta2 during mouse cortical development. Our results show that while they regulate a similar set of genes, their common direct targets are limited but include key regulators of cortical development. The identification of the interaction partners of Emx2 suggests that it coordinates with the LIM domain-binding protein Ldb1 to execute the activation and repression of some of its downstream targets. Finally, while Emx2 is known to suppress ChP development, we also provide evidence that Dmrta2 is, in contrast, required for ChP since in its absence in medial telencephalic progenitors, mice develop hydrocephalus postnatally, a phenotype that appears to be due to a compromised cytoarchitecture. Together, these data indicate that Emx2 and Dmrta2 have similar but also distinct functions in telencephalon development and provide the first insights into Emx2 mechanism of action.</p
