The overall behavior of a robot is emergent from coordination among its various parts and its interaction with its environment. Designing a `correct' robot which does`the right thing' in a given environment is an important and challenging problem. The question posed in the title is decomposed into two que...
متن کاملEast Siberia had a lower latitude in the Pleistocene
In Arctic East Siberia many remains of mammoths have been found. In this region there is not sufficient sunlight over the year to allow for the growth of the plants on which these animals feed.

It is a challenge to reconstruct this geographic shift of the poles in a manner compatib...
متن کاملTaenia sp. in human burial from Kan River, East Siberia
We present an arhaeoparasitological analysis of a unique burial from the Neftprovod II burial ground in East Siberia, which dated from the Bronze Age. Analysis of a sediment sample from the sacral region of the pelvis revealed the presence of Taenia sp. eggs. Because uncooked animal tissue is the primary source of Taenia, this indicated that the individual was likely consuming raw or undercooke...
متن کاملSurface ultraviolet radiation over east Siberia: seasonal variations
The results of spectral measurements of the daily near-noon surface direct solar ultraviolet radiation in the wavelength range of 295–345 nm obtained in Irkutsk (East Siberia) for the time interval of 1998–2000 are presented. For the period under consideration, the seasonal UV radiation variations are analysed that are associated with the total ozone dynamics, the transition of cyclonic and ant...
