Etude transcriptionnelle et post-transcriptionnelle de la région IR L/TR L du virus de la maladie de Marek / Transcriptionnal and post-transcriptionnal regulation of IRL/TRL regions of Marek's disease virus

Coupeau, Damien 09 June 2011 (has links)
Le Gallid Herpesvirus 2 (GaHV-2) est un herpesvirus responsable de lymphomes T chez le poulet. Son génome code pour 25 miARN matures regroupés en 2 clusters localisés au sein des régions répétées TRL/IRL etIRS/TRS. Mon travail a tout d’abord consisté en l’étude de la fonctionnalité des deux brins de mdv1-pré-miRM4sur deux cibles virales UL-28 et UL32. Le brin mdv1-miR-M4-5P ayant été identifié comme orthologue dumiARN cellulaire miR-155, leurs impacts ont été comparés sur six cibles cellulaires et la cible virale UL-28.Les différents miARN de GaHV-2 présentant des taux d’expression variables, nous avons identifié, dans larégion TRL/IRL, des ARNm responsables de leur transcription à partir d’exon ou d’intron. De plus, nous avonsidentifié un promoteur plutôt spécifique de la latence et responsable de la transcription de l’ensemble desmiARN de l’IRL/TRL, de l’oncogène meq et du transcrit Meq/vIL-8. / Gallid Herpesvirus 2 (GaHV-2) is a herpesvirus inducing T-lymphoma in chickens. Its genome encodes 25mature miRNAs splitted in two clusters localized in IRL/TRL and IRS/TRS repeated regions. In this work, wefirst analyzed the functionality of the two strands of mdv1-pre-miR-M4 on two viral targets named UL-28 andUL-32. As one strand of this miRNA was identified as an ortholog of cellular miRNA-155, their effects wereassessed on six cellular targets and on the UL-28 viral target. As a differential expression of miRNAs wasobserved during GaHV-2 infection, we found numerous IRL/TRL transcripts responsible for the intronic orexonic transcription of viral miRNAs. Moreover, we identified a latency promoter controlling at the same timetranscription of all IRL/TRL miRNAs, the oncogenic meq gene and the Meq/v-IL8 transcript.

Reconfigurabilidade dinâmica e remota de FPGAs. / Dynamic and remote reconfiguration of FPGAs.

Ribeiro, Alexandre Alves de Lima 22 August 2002 (has links)
Neste trabalho estudou-se diversas arquiteturas de dispositivos FPGAs presentes no mercado, visando a utilização desta tecnologia em arquiteturas de computação reconfigurável. Especificamente foram investigados recursos e técnicas de reconfigurabilidade dinâmica destes dispositivos. A possibilidade de reconfigurar dinamicamente o hardware cria diversas expectativas de superação das arquiteturas de computação tradicional. Surge o conceito de hardware virtual, assim como inúmeras dificuldades em utilizar efetivamente esta tecnologia. Outra característica promissora que a tecnologia FPGA oferece é a possibilidade de realizar upgrades remotos do hardware, sem a necessidade de substituição física de equipamentos ou parte deles. Em adicional, foi implementado um sistema multi-FPGAs com dispositivos reconfiguráveis individualmente de forma local ou remota. Este sistema poderá ser a base para uma arquitetura de computação reconfigurável, sendo ela dinâmica ou não. / In this work it was studied several architectures of FPGAs devices available in the market, seeking the use of this technology in architectures of reconfigurable computing. It was specifically researched resources and techniques of dynamic reconfiguration of these devices. The possibility of reconfigure the hardware dynamically creates countless expectations to overcome the architectures of traditional computing. The concept of virtual hardware emerges, as well as a lot of difficulties in using actually this technology. Another promising characteristic that the technology FPGA offers it is the possibility to accomplishing remote upgrades of the hardware, without the need of physical substitution of equipments or of parts of them. In addition, a system multi-FPGAs was implemented with individually reconfigurable devices in local or remote way. This system can be the base for an architecture of reconfigurable computing, being it dynamics or not.

Context-awareness for adaptive information retrieval systems

Agbele, Kehinde Kayode January 2014 (has links)
Philosophiae Doctor - PhD / This research study investigates optimization of IRS to individual information needs in order of relevance. The research addressed development of algorithms that optimize the ranking of documents retrieved from IRS. In this thesis, we present two aspects of context-awareness in IR. Firstly, the design of context of information. The context of a query determines retrieved information relevance. Thus, executing the same query in diverse contexts often leads to diverse result rankings. Secondly, the relevant context aspects should be incorporated in a way that supports the knowledge domain representing users’ interests. In this thesis, the use of evolutionary algorithms is incorporated to improve the effectiveness of IRS. A context-based information retrieval system is developed whose retrieval effectiveness is evaluated using precision and recall metrics. The results demonstrate how to use attributes from user interaction behaviour to improve the IR effectiveness

In Real Life (Or Elsewhere) : om kreativa processer och parallella verkligheter i dokumentärfilm

Nevanti, Kirsi January 2017 (has links)
Reality isn’t what it appears to be. Contexts are not always clear and visible. People don’t always say what they really mean. And they don’t always mean what they say. When life is your stage manager, anything can happen. I often say, life is hard, my head is harder. Making documentaries is not for the faint-hearted.This PhD project explores creative processes and parallel realities in documentary film, and discusses and conceptualizes the artistic practice of documentary filmmaking. The project consists in part of artistic works and essays that are critical reflections on the creative process and how that process can be conceptualized. The cinematic centerpiece of the thesis is entitled Images and the Worlds of Being (2011–2016). Previous subprojects are A Shift Between Worlds (2013–2015) and an essay book entitled In Real Life (or Elsewhere) (2013). Between 2013 and 2017, more essays were written, some of them translated to English. All the Swedish essays are available in PDF format. All of the works in the PhD project explore creative processes and parallel realities in two different ways: A Shift Between Worlds (2013–2015) explores identity and parallel realities in the gendered world. These works are based on two workshops led by Diane Torr, “Man for a Day” and “Woman for a Day.” They resulted in several component works, including two video essays, two audio works and two large-format photographic works, the latter in collaboration with photographer Johan Bergmark, as well as a short commentary film entitled Diane Speaks Out (2016). Images and the Worlds of Being (2011–2016) – a VR Classic Style film – explores what happens when documentary images are shown on four screens forming the walls of a room. This work also focuses on the view through the camera lens through which the filmmaker meets the world, in a hypnotic tapestry of parallel realities in a tenderly portrayed, runaway present. A sort of logical reasoning about the illogic of our era, in search of elusive reality (to paraphrase Jean Baudrillard) – the presence in the act of seeing. An experiment in the forms of visual knowledge, outside the traditional display windows. Shooting location: The World.
