The oncogenic transcription factors E2F and Myc bind to specific DNA sequences at distinct times during the G1 phase of the mammalian cell cycle, and regulate transcription of a plethora of target genes. E2F and Myc associate with TRRAP, a subunit of distinct macromolecular complexes that contain the histone acetyltransferases (HATs) Gcn5/PCAF or Tip60. During the course of my thesis I...

To cope with the daily changes in their environment, in organisms, from cyanobacteria to humans, endogenous clocks have evolved that anticipate these changes and synchronize physiology and behavior accordingly. In mammals, the central circadian pacemaker is located in the suprachiasmatic nuclei (SCN) of the hypothalamus. From there subordinated cellular clocks in the peripheral organs are...

This dissertation addresses three fundamental problems, which have to be handled in application domains like ubiquitous computing and Web services. The three problems heterogeneity, static configuration, and dynamic configuration are not only considered to persist during the near future but to increase, as similar application domains will emerge. The heterogeneity problem is defined and examples...

This thesis introduces a methodological approach to artificial agent design. In an attempt to solve the symbol grounding problem of artificial intelligence, a new theoretical perspective on the agent-environment relation is explored and experimentation is led to motivate this methodology. From the original idea that in order to ground an agent in an environment, the agent’s representation...

The future multi-layer optical networks based on wavelength division multiplexing technology will lead to the creation of new value-added optical services, which is bound to transform the traditional passive transport network into an active and intelligent transport layer. The successful deployment of these complex networking services and the possibility of subjecting them to a dynamic control,...

This thesis investigates the optimization of automated high-density storage systems at design stage and in control logic development. In modern storage technology, automated high-density storage systems offer a space saving alternative to traditional storage rack systems. They comprise several floors subdivided into parallel storage aisles and linking cross-aisles. Pallet movements are...

Life is a combustion, but how the major fuel substrates that sustain human life compete and interact with each other for combustion has been at the epicenter of research into the pathogenesis of insulin resistance ever since Randle proposed a 'glucose-fatty acid cycle' in 1963. Since then, several features of a mutual interaction that is characterized by both reciprocality and dependency between...

We present in this thesis a uniform approach to recognize the physical structure of printed documents that may contain various kinds of blocks: we call such documents composite documents. After an introduction to the subject of this thesis, we present first the state of the art in the field of document recognition. In this part, we present models and standards used to represent document...

Uncertain knowledge can be represented in the framework of argumentation systems. In this framework, uncertainty is expressed using so-called assumptions. Depending on the setting of the assumptions, a given hypothesis of interest can be proved or falsified. The main goal of assumption-based reasoning is to determine the set of all supporting arguments for a given hypothesis. Such a supporting...
