1. On Signal Dependent Basis Functions, Estimation of Event Related Potentials and Multiple Window Spectrum Analysis
Abstract : The three parts of this thesis are different examples of utilization of signal dependent basis functions in the estimation procedure. The first part surveys a number of parametric methods applied to estimation of single ERP (P300). READ MORE

2. Spatial decomposition of ultrasonic echoes
Abstract : The pulse-echo method is one of the most important in ultrasonic imaging. In many areas, including medical applications and nondestructive evaluation, it constitutes one of the fundamental principles for aquiring information about the examined object. READ MORE

3. HMGB1 : regulation of inflammatory functions and therapeutic blockade
Abstract : The intracellular protein High Mobility Group Box Protein 1 (HMGB1) has been identified as a pivotal mediator of inflammation. HMGB1 can be released by various mechanisms and as an inflammatory mediator it induces both migration of inflammatory cells and cytokine production. READ MORE

4. Phylogeny and Signal Diversity in Widowbirds and Bishops (Euplectes spp.)
Abstract : Although sexual selection for elaborate signals is well documented in numerous species, the extreme diversity in signal design and expression in many taxa is largely unexplained. This thesis explores phylogenetic, mechanistic and ontogenetic explanations for divergence in two classic condition-dependent signal traits in the African widowbirds and bishops (Euplectes spp. READ MORE

5. Modulation of natural killer cell and T-cell functions by CD94/NKG2A receptors
Abstract : Natural Killer (NK) cells constitute a subset of lymphocytes capable of cytokine production and/or cellular cytotoxicity. Although NK cells can be activated experimentally by a multitude of agents, the in vivo mechanisms of activation and regulation are not fully elucidated. READ MORE
