In an earlier paper (Nunez & Colhoun 1986), the gradient of near-surface air temperature with altitude, commonly known as the environmental lapse rate (ELR), was obtained for Mount Wellington, Tasmania. Comparing these local lapse rates with an ELR for the entire island did not give good agreement for maximum temperatures in summer or minimum temperatures in winter. These differences are attrib...

A picture of a bush dog Speothos venaticus was obtained with a minimum sampling effort of 4,818 camera days, using seven to ten era traps during 922 days at Parque Estadual Carlos Botelho, an Atlantic forest site. This picture confirms the presence of the species the state of São Paulo, Brazil.

The eligibility trace is one of the most used mechanisms to speed up reinforcement learning. Earlier reported experiments seem to indicate that replacing eligibility traces would perform better than accumulating eligibility traces. However, replacing traces are currently not applicable when using function approximation methods where states are not represented uniquely by binary values. This pap...
