Early temperamental traits in an octopus (Octopus bimaculoides).
During their 3rd week of life, 73 Octopus bimaculoides were observed to test whether discrete behaviors could be grouped reliably to reflect dimensions of temperament. Frequencies of behaviors during Week 3 were subjected to principal-components analysis (PCA), resulting in 4 components (active engagement, arousal/readiness, aggression, and avoidance/disinterest) that explain 53% of the varianc...
متن کاملAlgorithms for graphs with small octopus
A d-octopus of a graph G = (V; E) is a subgraph T = (W; F) of G such that W is a dominating set of G, and T is the union of d (not necessarily disjoint) shortest paths of G that have one endpoint in common. First, we study the complexity of 5nding and approximating a d-octopus of a graph. Then we show that for some NP-complete graph problems that are hard to approximate in general there are e9c...

This chapter discusses the interconnection architecture of the Mobile Digital Companion. The approach to build a low-power handheld multimedia computer presented here is to have autonomous, reconfigurable modules such as network, video and audio devices, interconnected by a switch rather than by a bus, and to offload as much as work as possible from the CPU to programmable modules placed in the...
متن کاملDeath and the octopus
It does not happen often that a zoology class turns emotional, but I recall vividly how a fi lm we were shown as undergrads, a production of the notoriously unromantic German Institut für Film und Wissenschaft, left us with an eerie sense of wonder and sadness. The subject was the life cycle of the octopus, and a female was being observed in an aquarium as she laid her clutch of thousands of eg...
