Cosmological Parameters 2006 Ariel G . Sánchez 1 , and Carlton

Recent measurements of the cosmic microwave background radiation (CMB), particularly when combined with other datasets, have revolutionised our knowledge of the values of the basic cosmological parameters. Here we summarize the state of play at the end of 2006, focusing on the combination of CMB measurements with the power spectrum of galaxy clustering. We compare the constraints derived from t...

As a former student of Professor Ostrowski—one of his last— I am delighted to recall here the life and work of one of the great mathematicians of the 20th century. Needless to say that, in view of Ostrowski’s immense and vastly diverse mathematical legacy, this can be done only in a most summary fashion. Further literature on Ostrowski can be found in some of the references at the end of this a...

Cluster Analysis for Large Scale Gene Expression Studies High throughput gene expression analysis is becoming more and more important in many areas of biomedical research. cDNA microarray technology is one very promising approach for high throughput analysis and provides the opportunity to study gene expression patterns on a genomic scale. Thousands or even tens of thousands of genes can be spo...

Alexander Borst

Alexander Borst studied Biology at the University of Wuerzburg. His PhD work in Martin Heisenberg’s lab demonstrated that the mushroom bodies of Drosophila are indispensable for olfactory learning. He did a postdoc with Karl Goetz at the Max-PlanckInstitute for biological Cybernetics in Tübingen, where he started to work on fly motion vision, a field which he never left since. In 1993, he becam...
