Abstract:
Tunicata umfasst 3000 marine Arten, mit sehr unterschiedlichen Lebensstrategien. Als eines der drei großen Taxa innerhalb der Chordata, stellt die Evolution der Tunikaten eine Schlüsselkomponente bei der Aufklärung der Evolution der Chordaten und Cranioten dar. Dafür ist ein Verständnis der Merkmalstransformationen innerhalb der Tunikaten notwendig. Leider sind die internen Verwandtschaftsverhältnisse der fünf großen Tunikatentaxa in verschiedenen molekularphylogenetischen Studien widersprüchlich. Bisher gibt es nur wenige morphologische phylogenetische Analysen. Ein Schwerpunkt dieser Arbeit

Abstract:
The topic of this thesis is black virus disinfection using mobile agents. The black virus is a faulty node that destroys any visiting agent without leaving a trace; moreover, once the black virus is triggered by an agent, it clones itself and spreads to neighbouring nodes. These viruses can only be destroyed if they move to nodes that have been occupied by agents. In this thesis, we consider the black virus disinfection problem in chordal rings. Initially, the system contains a single black virus that resides at an unknown location. We propose a solution that involves deploying a team of mobil

Chordoma is a rare malignant tumour of bone, the molecular marker of which is the expression of the transcription factor T (also referred to as brachyury). Silencing of T induces growth arrest in chordoma cell lines; however its downstream genomic targets are unknown. In this thesis I have identified these targets with validation in human chordoma samples. This was achieved by using an integrated functional genomics approach involving shRNA-mediated brachyury knockdown, gene expression microarray, ChIP-seq experiments and bioinformatics analyses.

The classes of chordal and complete hypergraphs are introduced and studied in Chapter 2 and Chapter 3 respectively. Chapter 4, that is the content of \cite{E5}, answers a question posed at the P

Evolutionary studies of the mitochondrial genome (mtDNA) have been widely used to solve phylogenetic controversies and to analyse the mechanisms of whole genome evolution.

Moreover, the strong correlation between mitochondrial structural features and functional processes like the replication and transcription of mtDNA increases the importance to deeply investigate the mitochondrial genomic features.

Using a relationship between chordal graphs and sparse semidefinite matrices, we decompose the semidefinite constraints in the associated SDP problems into multiple, smaller semidefinite constraints along with some additional equality constraints.

Abstract:
Most multicellular organisms have body plans that exhibit an element of symmetry; either radial or bilateral symmetry.
