Traveling Companions Add Complexity and Hinder Performance in the Spatial Behavior of Rats

We sought to uncover the impact of the social environment on the spatial behavior of rats. Food-deprived rats were trained in a spatial task of collecting food items from 16 equispaced objects. Following training, they were tested, first alone and then with a similarly-trained cage-mate. It was found that the presence of another rat substantially altered the rats' spatial behavior. Lone rats co...

Lifelong companions

The life of an RNA molecule is complicated. Once a newly synthesized eukaryotic RNA has emerged from the RNA polymerase in the nucleus, it will be processed, spliced, and exported into cytoplasm. In prokaryotes, transcribed RNA is synthesized directly in the cytoplasm. RNA molecules that serve as mRNAs have to be kept devoid of local structures that are inhibitory for ribosome scanning and tran...

As will become clear, I wish to explore these topics in terms which are basically those of computational linguistics; and by ‘machines’ here, I intend software entities, rather than robots, and in particular the sort of softw...

Over thousands of years, these travellers unknowingly carried excess baggage on their journeys: countless microbes in and on their bodies, which evolved along with their host. By applying the tools of modern genomics...

Companions, Causality and Codensity

In the context of abstract coinduction in complete lattices, the notion of compatible function makes it possible to introduce enhancements of the coinduction proof principle. The largest compatible function, called the companion, subsumes most enhancements and has been proved to enjoy many good properties. Here we move to universal coalgebra, where the corresponding notion is that of a final di...
