We propose a hypothesis of the truncation of stellar discs based on the magnetic model of the rotation curve of spiral galaxies. Once the disc had formed and acquired its present structure, approximately, three balanced forces were acting on the initial gas: gravity and magnetic forces, inwards, and centrifugal force. When stars are formed from this gas, the magnetic force is suddenly suppresse...

ASTRACT.This paper analyzes the structure of a relatively neglected resource in Tlingit and Northwest Coast etlmology: berries. Historically, like salmon streams and other key resource areas among the Tlingil of Southeast Alaska, prime berry patches were named, owned, managed, and celebrated as places. Certain berries, including those found in the vicinity of Glacier Bay National Park, were rec...

Symbolic path planning in autonomous robotic agents is the search, on a network of places and routes modeling the environment, for a sequence of routes which enables an agent to execute a set of interrelated tasks. When several agents are present in the environment, each having been assigned a set of tasks, the adoption of coordination mechanisms allows the task-execution costs to be decreased....

Hitting a target in seeking the key to the author’s self-concept is undertaken through the c...
