The ambivalent identity of Wong Kar-wai's cinema

Moreira Macedo de Carvalho, Ludmila 06 1900 (has links)
Ayant réalisé neuf longs-métrages entre 1988 et 2007, aussi que plusieurs campagnes publicitaires, vidéo-clips, courts-métrages et projets collectifs, Wong Kar-wai est un des réalisateurs contemporains les plus importants actuellement. Issu de l'industrie cinématographique fortement commerciale de Hong Kong, Wong est parvenu à attirer l'attention du circuit international des festivals de cinéma avec son style visuel unique et son récit fragmenté. Considéré par plusieurs critiques comme le poète de la recherche d’identité de Hong Kong après 1997, Wong Kar-wai défie toutes les tentatives de catégorisation. L’étude qui se poursuivit ici a donc pour objet essentiel de fournir une analyse attentive et complète de son oeuvre, tout en se concentrant sur les traits stylistiques qui donnent à ses films une unité. Ces caractéristiques correspondent à une certaine façon de raconter des histoires, de composer des personnages et des récits, de manipuler le temps et d'utiliser des ressources techniques de sorte que ses films offrent une identité cohérente. L'objectif est d'analyser les différents composants de ses images pour découvrir comment ses films communiquent les uns avec les autres afin de créer une identité unique. Pour atteindre cet objectif, je pose comme hypothèse de travail que le cinéma de Wong est marqué par une structure dualiste qui permet à ses films de présenter des qualités contradictoires simultanément. La plupart de mes arguments se concentrent sur le travail du philosophe français Gilles Deleuze, qui a proposé une théorie du cinéma divisé entre l’image-mouvement et l’image-temps. Je considère que sa théorie fournit un cadre valide sur lequel les films de Wong peuvent être projetés. Tandis que ma recherche se concentre sur l’interprétation textuelle des films, je profiterais également d’une analyse comparative. / With nine feature films released between 1988 and 2007, as well as several advertising campaigns, music videos, short films and collective projects, Wong Kar-wai is one of the most important contemporary filmmakers currently working. Hailing from Hong Kong’s highly commercial film industry, Wong has managed to attract the attention of the international film festival circuit with his visual style and fragmented narrative. Considered by many critics as the poet of Hong Kong’s quest for identity post 1997, his cinema defies every attempt of standardization. The main goal of this study is to provide an attentive and comprehensive study of his body of work, concentrating on the stylistics traits that make his films part of a coherent unity. These characteristics correspond to a certain way of telling stories, of composing situations and characters, of manipulating time and the use of technical resources so that his films offer a coherent identity. The objective is to analyze the different components of his images, to show how his films communicate with each other in order to create something unique. To achieve this objective, I put forward the hypothesis that Wong’s cinema is marked by a dualistic structure that allows his films to present opposite qualities at the same time. Most of my arguments are based on the thoughts of French philosopher Gilles Deleuze, whose own dualistic theory of cinema presented in his books Cinema 1: the movement-image and Cinema 2: the time-image, provides a valid framework upon which Wong’s films can be projected. While the research concentrates on the textual analysis of films, I will also benefit from comparative analysis and additional disciplines.

Room 2046: A Political Reading of Wong Kar-Wai's Chow-Mo Wan Trilogy through Narrative Elements and Mise-en-scene

Baldwin, Jillian 12 1900 (has links)
As ownership of Hong Kong changed hands from the United Kingdom to the People's Republic of China in 1997, citizens and filmmakers of the city became highly aware of the political environment. Film director Wong Kar-Wai creates visually stimulating films that express the anxieties and frustrations of the citizens of Hong Kong during this period. This study provides a political reading of Days of Being Wild (1991), In the Mood for Love (2000), and 2046 (2004) through analyzing various story elements and details within the mise-en-scene. Story elements include setting, dialogue, character relationships, character identities, thematic motifs, musical references, numerology, and genre manipulation. Wong also uses details within the films' mise-en-scene, such as props and color, to express political frustrations. To provide color interpretations, various traditional aesthetic guidelines, such as those prescribed by Taoism, Cantonese and Beijing opera, and feng shui, are used to read the films' negative comments on the handover process and the governments involved. When studied together the three films illustrate how Wong Kar-Wai creates narrative and visual references to the time and atmosphere in which he works, namely pre-and-post handover Hong Kong.

OBJECT DETECTION USING VISION TRANSFORMED EFFICIENTDET

Shreyanil Kar (16285265) 30 August 2023 (has links)
<p>This research presents a novel approach for object detection by integrating Vision Transformers (ViT) into the EfficientDet architecture. The field of computer vision, encompassing artificial intelligence, focuses on the interpretation and analysis of visual data. Recent advancements in deep learning, particularly convolutional neural networks (CNNs), have significantly improved the accuracy and efficiency of computer vision systems. Object detection, a widely studied application within computer vision, involves the identification and localization of objects in images.</p> <p>The ViT backbone, renowned for its success in image classification and natural language processing tasks, employs self-attention mechanisms to capture global dependencies in input images. However, ViT’s capability to capture fine-grained details and context information is limited. To address this limitation, the integration of ViT into the EfficientDet architecture is proposed. EfficientDet is recognized for its efficiency and accuracy in object detection. By combining the strengths of ViT and EfficientDet, the proposed integration enhances the network’s ability to capture fine-grained details and context information. It leverages ViT’s global dependency modeling alongside EfficientDet’s efficient object detection framework, resulting in highly accurate and efficient performance. Noteworthy object detection frameworks utilized in the industry, such as RetinaNet, EfficientNet, and EfficientDet, primarily employ convolution.</p> <p>Experimental evaluations were conducted using the PASCAL VOC 2007 and 2012 datasets, widely acknowledged benchmarks for object detection. The integrated ViT-EfficientDet model achieved an impressive mean Average Precision (mAP) score of 86.27% when tested on the PASCAL VOC 2007 dataset, demonstrating its superior accuracy. These results underscore the potential of the proposed integration for real-world applications.</p> <p>In conclusion, the research introduces a novel integration of Vision Transformers into the EfficientDet architecture, yielding significant improvements in object detection performance. By combining ViT’s ability to capture global dependencies with EfficientDet’s efficiency and accuracy, the proposed approach offers enhanced object detection capabilities. Future research directions may explore additional datasets and evaluate the performance of the proposed framework across various computer vision tasks.</p>

Biblijos horizontas XXa. šeštojo dešimtmečio kartos lietuvių poetų kūryboje / The Biblical horizon in the XXth century 6th decade generation Lithuanian poets' ceation

Norvaišaitė, Rasa 03 June 2005 (has links)
Summary The architectonics of the Biblical horizon allow to perceive, and highlight the ideological and semantical poetical kernel of the XXth century 6th decade poets’ generation. While highlighting the peculiarity of the Biblical horizon and revealing the semantical kernels of writers’ apprehension and poetical worldview, the theoretical hermeneutical principle of text reading is chosen. A reference is made to the perspective of Ricoeuras, which formulates the tradition of hermeneutical symbol and metaphor apprehension. The Biblical horizon is perceived according to the three poetical traditions of the Scripture re-creating. That would be: the structure of views proning to the logycs of rebellion and myth, the poetical principle of sensual and perceptual relation to the things, the intelectual novation of the biblical religious architectonics. The creation of these poets, representing diverse poetical traditions, idividually transform (Platelis, Kajokas, Gailius, Cieškaitė) or deform (Patackas) the notional field of the Scripture. In Patackas and Platelis poetry, representing the verse of death or reflection, for pointing out the Biblical horizon is important the mythopoetical cogitation which brings forward the dominant of rebellion, related to the sociocultural apprehension and revealing the Biblical typology of banishment from the paradise. Patackas poetry points out the perspective of the profanic paradygme, demythologization of the biblical images, semantical... [to full text]

Role of the 17-beta-hydroxysteroid dehydrogenase type 12 (HSD17B12) in hepatitis C and related flaviviruses replication.

Mohamed, Bassim 08 1900 (has links)
Dans le monde entier, les infections virales causent des problèmes de santé majeurs et récurrents, engendrant de sérieux problèmes socio-économiques. Notamment, les virus de la famille Flaviviridae qui représentent un fardeau considérable sur la santé mondiale et font partie des domaines prioritaires de la virologie médicale selon le rapport 2016 du ‘Global Virus Network’. Bien que le traitement actuel contre le virus de l’hépatite C (VHC) ait un taux de guérison dépassant 98%, d’autres comme le virus de la dengue (DENV) et le virus zika (ZIKV) n’ont pas encore de traitement spécifique autorisé. En prenant avantage de la grande expertise de notre laboratoire dans l’étude du VHC, nous avons utilisé des données d’une étude de biologie des systèmes visant à identifier l’interactome des différentes protéines virales. Les techniques utilisées ont combiné l’immunoprécipitation des protéines virales suivie de l’identification des protéines interacteurs humaines par spectrométrie de masse. Des études de génomique fonctionnelle par ARN interférent (ARNi) ont permis d’étudier l’effet de la diminution de l’expression des protéines identifiées sur la réplication du VHC. Cette étude a conduit à la découverte de l’interactant spécifique 17-bêta-hydroxystéroïde déshydrogénase de type 12 (HSD17B12 ou DHB12) de la protéine virale Core comme facteur cellulaire requis à la réplication du VHC. HSD17B12 est une enzyme cellulaire dont l’activité catalytique est requise pour l’élongation des acides gras à très longue chaîne (VLCFA) lors de la deuxième des quatre réactions du cycle d’élongation. Dans cette étude, nous avons déterminé que les cycles de réplication du VHC, ZIKV et DENV dépendent de l’expression et de l’activité métabolique du facteur cellulaire HSD17B12. Ainsi, nous avons étudié les effets de l’inhibition de l’expression génique par ARNi et de façon pharmacologique sur la réplication de plusieurs flavivirus dans une approche antivirale à large spectre. Nous avons démontré que le silençage de HSD17B12 diminue significativement la réplication virale, l’expression des protéines virales et la production de particules infectieuses de cellules Huh7.5 infectées par la souche JFH1 du VHC. L'analyse de la localisation cellulaire de HSD17B12 dans des ii cellules infectées suggère une colocalisation avec l'ARN double brin (ARNdb) aux sites de réplication virale, ainsi qu’avec la protéine Core (et les gouttelettes lipidiques) aux des sites d’assemblage du virus. Nous avons également observé que le silençage de HSD17B12 réduit considérablement le nombre et la taille des gouttelettes lipidiques. En accord avec ces données, la diminution de l’expression de HSD17B12 par ARNi réduit significativement l’acide oléique et les espèces lipidiques telles que triglycérides et phosphatidyl-éthanolamine dans l'extrait cellulaire total. Ces travaux suggèrent une contribution de la capacité métabolique de HSD17B12 lors de la réplication du VHC. De même, nous avons démontré que le silençage de HSD17B12 réduit significativement les particules infectieuses de cellules infectées par DENV et ZIKV. Ces études supportent le rôle de HSD17B12 dans l’efficacité des processus de la réplication de l'ARN viral et de l’assemblage de particules virales. De plus, l'inhibiteur spécifique de HSD17B12, INH-12, réduit la réplication du VHC à des concentrations pour lesquelles aucune cytotoxicité notable n'est observée. Le traitement avec 20 μM d'INH-12 réduit jusqu'à 1,000 fois les particules infectieuses produite par des cellules Huh-7.5 infectées par DENV et ZIKV lors de plusieurs cycles de réplication, et bloque complètement l'expression des protéines virales. En conclusion, ces travaux ont conduit à une meilleure compréhension du rôle de HSD17B12 lors de la synthèse de VLCFA et de lipides requise à la réplication du VHC, permettant d’explorer l’inhibition de HSD17B12 et de l’élongation d’acides gras à très longue chaîne comme nouvelle approche thérapeutique pour le traitement à large spectre des infections par les virus de la famille Flaviviridae. / Infections with viruses are major recurrent socio-economical and health problems worldwide. These include infections by viruses of the Flaviviridae family, which present a substantial global health burden and are among the priority areas of medical virology according to the Global Virus Network 2016 report. While the current treatment regimens for hepatitis C virus (HCV) infection have cure rates of more than 98%, other important members of Flaviviridae like dengue virus (DENV) and zika virus (ZIKV) have no specific licensed treatments. By taking advantage of the most-studied HCV, which our lab has developed a vast expertise in the last 20 years, we used proteomics data of an HCV interactome study, combining viral protein immunoprecipitation (IP) coupled to tandem mass spectrometry identification (IP-MS/MS) and functional genomics RNAi screening. The study uncovered the 17-beta-hydroxysteroid dehydrogenase type 12 (HSD17B12, also named DHB12), as a specific host interactor of core that promotes HCV replication. HSD17B12 catalytic activity is involved in the synthesis of very-long-chain fatty acids (VLCFA) upon the second step of the elongation cycle. In this study, taking HCV as a virus model, we elucidated the dependency of HCV, dengue virus (DENV) and zika virus (ZIKV) replication on expression and metabolic capacity of the host factor HSD17B12. We investigated the effects of the inhibition of gene expression by RNAi and of its pharmacological enzymatic inhibition on flavivirus replication in a broad-spectrum antiviral approach. We showed that silencing expression of HSD17B12 decreases viral replication, viral proteins and iv infectious particle production of the JFH1 strain of HCV in Huh7.5 cells. The cellular localization analysis of HSD17B12 showed a co-staining with double-stranded RNA (dsRNA) at viral replication sites and with core protein (and lipid droplets) at virus assembly sites. Furthermore, HSD17B12 gene silencing drastically reduced the number and size of lipid droplets. In association, the reduced expression of HSD17B12 by RNAi decreases oleic acid levels and lipids such as triglycerides (TG) and phosphatidylethanolamine (PE) in whole-cell extract. The data suggested the requirement of the metabolic capacity of HSD17B12 for HCV replication. Similarly, we provide evidence that HSD17B12 silencing significantly reduces DENV and ZIKV infectious particles. The studies support a role of HSD17B12 for effective viral RNA replication and particle assembly processes. Moreover, the specific HSD17B12 inhibitor, INH-12, reduces HCV replication at concentrations for which no appreciable cytotoxicity is observed. The treatment of DENV- and ZIKV-infected Huh- 7.5 cells with 20 μM of INH-12 dramatically reduces production of infectious particles by up to 3-log10 in infection assays, and completely block viral protein expression. In conclusion, these studies extends our understanding of the role of HSD17B12 in VLCFA synthesis required for the replication of HCV, allowing to explore the inhibition of HSD17B12 and elongation of VLCFA as a novel therapeutic approach for the treatment of a broad-spectrum of viruses of the Flaviviridae family.
