The model's basic unit is a particle with a mass of approximately one billion suns (in order to sample galaxies with masses of about a trillion suns), and it includes 64 billion and more of those particles. The model is one of the largest simulations of the distribution of matter in the universe, and aims to look at galaxy-scale mass concentrations above and beyond quantities seen in state-of-the-art sky surveys.

Finding relevant information is sometimes like finding 'a needle in a haystack'. A typical MEDLINE search retrieves a lot of irrelevant data and misses highly pertinent articles. One way to improve searching is to filter MEDLINE for a clinical discipline. The research team tested over one million 'renal' filters, using an empiric approach to discover those with high performance.
