On shunting over a hump
We consider the situation of rearranging freight trains in a shunting yard with a hump and several tracks. Here, an elementary shunting operation is to push a all cars of one track over the hump. On the way back to the tracks the cars can be guided individually to an arbitrary track. The goal is to create one or several trains that have their cars in a particular order. We measure the efficienc...

متن کامل'Back to the future': how archaeological remains can describe salmon adaptation to climate change.
A strategy for species to survive climate change will be to change adaptively their way of life. Understanding rapid adaptation to climate change is therefore a priority for current research. In this issue, Turrero et al. (2012) use an original approach to unravel life history trait responses to climate change in two fish species (Salmo trutta and S. salar). Going against the flow, the authors ...
