Red tree vole Red tree vole The red tree vole ("Arborimus longicaudus") is a rodent found in Oregon and California. The red tree vole is a rodent in the family Cricetidae. It is found only in coastal forests of Oregon and northern California. They eat exclusively the needles of conifers, mostly Douglas-fir ("Pseudotsuga menziesii") and occasionally other species. They often spend their lives in just one tree, and many generations will live in different parts of the same tree. When eating Douglas-fir needles, they carefully remove the fine resin ducts (which resemble coarse, straight hairs) along each edge of the needle, discarding these
Tree automaton three statements are equivalent: Tree automaton A tree automaton is a type of state machine. Tree automata deal with tree structures, rather than the strings of more conventional state machines. The following article deals with branching tree automata, which correspond to regular languages of trees. As with classical automata, finite tree automata (FTA) can be either a deterministic automaton or not. According to how the automaton processes the input tree, finite tree automata can be of two types: (a) bottom up, (b) top down. This is an important issue, as although non-deterministic (ND) top-down and ND bottom-up tree automata are
