When Women Lead Change Happens

What happens when Penelope comes?

Transposable elements (TEs) are ubiquitous residents in eukaryotic genomes. They can cause dramatic changes in gene expression and lead to gross rearrangements of chromosome structure, providing the basis for rapid evolution. The virilis species group of Drosophila contains certain species that can be crossed under experimental conditions and their phylogeny is thoroughly investigated. We have ...

What happens when Trypanosoma brucei leaves Africa.

Julius Lukes and co-workers evaluated the evolutionary origin of Trypanosoma equiperdum and Trypanosoma evansi, parasites that cause horse and camel diseases. Although similar to T. brucei, the sleeping-sickness parasite, these trypanosomes do not cycle through the tsetse fly and have been able to spread beyond Africa. Transmission occurs sexually, or via blood-sucking flies or vampire bats. Th...

Both authors have contributed to all parts of the report. Conclusions where made through discussion.

Stagnation Analysis in Particle Swarm Optimisation or What Happens When Nothing Happens

The "classical" version of Particle Swarm Optimiser (PSO) is very simple but, before it can be executed, the user needs to define some parameters (swarm size, neighbourhoods, and some coefficients). Adaptive versions, like TRIBES [1, 2, 4], don't have this drawback. Also, they can often be more effective when compared to the classical PSO using a performance criterion which takes into account o...
