Discours de repentance ou repentance dans le discours: cas des commentaires sur Youtube
No full textThe present article attempts to examine online commentary as a discursive genre that has been profoundly transformed by the rise of the web, where the digital space becomes a site of direct expression, often marked by strong emotional intensity, a polemical tone, and at times even verbal violence. Through an analysis of the reactions sparked by a YouTube interview with Benjamin Stora—in which he discusses his report on the Algerian War—the author focuses in particular on the discourses and counter-discourses that emerge around the sensitive issues of repentance and non-repentance. These comments, posted by internet users in the video’s comment section, reveal a wide range of ideological positions and a great diversity of argumentative approaches. The central aim of this article is to identify and describe the types of arguments used by commenters, as well as the discursive strategies they employ to assert, justify, or challenge often opposing viewpoints. The study is situated within the field of argumentation in digital discourse, drawing on the theoretical framework proposed by Patrick Charaudeau, particularly his work on the discourse of repentance, as well as on the contributions of Marianne Doury concerning the typology of arguments and the construction of controversy. The author thus highlights how the dynamics of online debate—although often conflictual—contribute to the redefinition of collective memory surrounding a colonial past that remains vivid in the Franco-Algerian imaginary.L’article examine le commentaire en ligne en tant que genre discursif profondément transformé par l’essor du web, où l’espace numérique devient un lieu d’expression directe, souvent marquée par une forte charge émotionnelle, un ton polémique et parfois même une violence verbale. À travers l’analyse des réactions suscitées par une interview de Benjamin Stora diffusée sur YouTube — interview dans laquelle il revient sur son rapport consacré à la guerre d’Algérie, l’auteur de l’article s’intéresse plus particulièrement aux discours et contre-discours qui émergent autour des notions sensibles de repentance et de non-repentance. Ces interventions, laissées par des internautes dans l’espace commentaire, révèlent une pluralité de positions idéologiques et une grande diversité argumentative. L’objectif central de l’article est d’identifier et de décrire les types d’arguments mobilisés par les internautes, ainsi que les stratégies discursives qu’ils emploient pour affirmer, justifier ou contester des points de vue parfois antagonistes. L’étude se situe dans le champ de l’analyse de l’argumentation dans les discours numériques, en prenant appui sur le cadre théorique proposé par Patrick Charaudeau, notamment ses travaux sur le discours de repentance, ainsi que sur les apports de Marianne Doury concernant la typologie des arguments et la construction des controverses. L’auteur met ainsi en lumière comment les dynamiques de débat en ligne, bien que souvent conflictuelles, participent à la redéfinition de la mémoire collective autour d’un passé colonial toujours vif dans l’imaginaire franco-algérien

Metamaterial-enhanced four-port MIMO antenna for 5G communications at 28/38 GHz
Full text linkThis work presents a novel compact four-port multiple-in multiple-out (MIMO) antenna enhanced with metamaterial unit cells for 5G millimeter-wave (mmWave) applications at 28 and 38 GHz. Compact MIMO antennas at mmWave bands often suffer from high mutual coupling, which degrades isolation and diversity performance. To address this, the proposed design integrates metamaterial loading around each radiating element to effectively suppress coupling, enhance isolation, and improve overall efficiency. The antenna, measuring 27×27×0.8 mm³, is implemented on a flexible FR4_epoxy substrate (εr=4.4), enabling compatibility with portable and embedded devices. Full-wave simulations performed in both ANSYS high-frequency structure simulator (HFSS) and computer simulation technology (CST) studio suite confirm the effectiveness of the approach, achieving an exceptionally low envelope correlation coefficient (ECC) (0.0001), a fivefold reduction in channel capacity loss (CCL), and a wide impedance bandwidth of 25.90–34.93 GHz with |S11| below −10 dB in both operating bands. The design also exhibits stable directional gain and low sidelobes. Compared with recent compact MIMO antennas reported in the literature, the proposed configuration offers significantly improved isolation, bandwidth, and mechanical flexibility. These features make it a strong candidate for integration into high-capacity 5G modules, portable terminals, and compact internet of things (IoT) communication systems
