Real Time 3D Navigation In A Static Virtualized Scene From A Limited Set Of 2D Data
"... Among the new data processing services and applications, virtual navigation in a real 3D world takes more and more importance and requires specific research. With regard to the reactions of the most important part of net surfers for example, we think that for a user of an interactive immersive tool, ..."

, it is absolutely necessary to obtain a real time rendering of the virtual world, as natural and realistic as possible. That is why we focus our work on an image based approach, avoiding the slow and heavy handling of 3D models of the scene, generally not very realistic and typical in geometry based approaches
Culture on the Rise: How and Why Cultural Membership Promotes Democratic Politics
"... Abstract Selectively using Tocqueville, many social scientists suggest that civic participation increases democracy. We go beyond this neo-Tocquevillian model in three ways. First, to capture broader political and economic transformations, we consider different types of participation; results chang ..."

Within-host population dynamics and the evolution of microparasites in a heterogeneous host population,
- Evolution
, 2002
"... Abstract. Why do parasites harm their hosts? The general understanding is that if the transmission rate and virulence of a parasite are linked, then the parasite must harm its host to maximize its transmission. The exact nature of such trade-offs remains largely unclear, but for vertebrate hosts it ..."

Visual word recognition in bilinguals: Phonological priming from the second to the first language.
- Journal of Experimental Psychology: Human Perception and Performance,
, 2002
"... In this study, the authors show that cross-lingual phonological priming is possible not only from the 1st language (L1) to the 2nd language (L2), but also from L2 to L1. In addition, both priming effects were found to have the same magnitude and to not be related to differences in word naming laten ..."

Analyses of variance (ANOVAs) with three variables (language group of the participants, language of the words, and word frequency) revealed a reliable main effect of word frequency, F 1 (3, 168) ϭ 39.53, MSE ϭ 238, p Ͻ .01, and F 2 (3, 306) ϭ 19.67, MSE ϭ 713, p Ͻ .01, but this effect
Recruitment of Cln3 cyclin to promoters controls cell cycle entry via histone deacetylase and other targets
- PLoS Biol. 2009
"... In yeast, the G1 cyclin Cln3 promotes cell cycle entry by activating the transcription factor SBF. In mammals, there is a parallel system for cell cycle entry in which cyclin dependent kinase (CDK) activates transcription factor E2F/Dp. Here we show that Cln3 regulates SBF by at least two different ..."

, possibly by titrating Cln3. Since Rpd3 is the yeast ortholog of mammalian HDAC1, there is now a virtually complete analogy between the proteins regulating cell cycle entry in yeast (SBF, Cln3, Whi5 and Stb1, Rpd3) and mammals (E2F, Cyclin D, Rb, HDAC1). The cell may titrate Cln3 molecules against

I/O Paravirtualization at the Device File Boundary
"... Paravirtualization is an important I/O virtualization technol-ogy since it uniquely provides all of the following benefits: the ability to share the device between multiple VMs, sup-port for legacy devices without virtualization hardware, and high performance. However, existing paravirtualization so ..."

While this is a general problem, it explicitly applies to web-based services. However, Byzantine fault-tolerant (BFT) replicat ..."

ii iv vTo my parents vi vii Acknowledgements I would first and foremost extend my whole-hearted gratitude to my advisors, An-drea Arpaci-Dusseau and Remzi Arpaci-Dusseau. Andrea and Remzi are the reason that I had the opportunity for this exceptional Ph.D. journey. To this day, I still re-member the moment when they took me as their student and the joy and hope in my heart. Andrea and Remzi have showed me what systems research is like and how much fun and challenging it can be. Before this journey with them, I had always liked and believed in the beauty of mathematics and theory. My initial interest in systems research happened when I took Remzi’s Advanced Operating Systems
