ACORN: a review.
The ACORN system was originally developed as a means of ab initio solution of protein structures when atomic resolution data were available. The first step is to obtain a starting set of phases, which must be at least slightly better than random.

متن کاملAcorn poisoning in cattle.
Ten cows in a suckler herd totalling 60 sickened after grazing parkland which was heavily covered with acorns. Two died. The main clinical signs were dullness, anorexia and constipation.

متن کاملA Performance Evaluation of the Acorn
ACORN (Agent-based Community Oriented Retrieval Network) is a multi-agent system which uses agents to provide information across inter-net/intranet networks. In this report, we adapt the ACORN architecture for its performance evaluation on single and multiple servers, running on single and multiple machines. In order to evaluate the performance of ACORN, we introduce a novel concept of multiple...
متن کاملAcorn Production Patterns
Acorns—the fruits of oaks—are a key resource for wildlife in temperate forests throughout the Northern Hemisphere. Acorns are also economically important for extensive livestock rearing, and as a staple food have supported indigenous human populations. Consequently, differences in how individual trees and populations of oaks invest in acorn production, both in terms of the size of the acorn cro...
