Local Organizer

Many biomedical ontologies have now been developed, stimulated by the increasing importance of biomedical ontologies in the scientific community. Most ontology development efforts have required not only the participation of ontology engineers but also of domain experts. This should help the veracity of the domain knowledge, but not necessarily the engineering of the ontology. In fact, the quali...

Address-Independent Routing for Local Networks

A routing methodology is introduced which permits messages to be propagated throughout a network without recourse to destination or origin addresses. Two classes of networks, bidirectional trees and augmented rings, are analyzed from this point of view. An optimality property is proved for the bidirectional tree, and three types of address-independent routing strategies are derived. It is shown...

Goosecoid and the organizer.

The molecular nature of Spemann's organizer phenomenon has long attracted the attention of embryologists. goosecoid is a homeobox gene with a DNA-binding specificity similar to that of Drosophila bicoid. Xenopus goosecoid is expressed on the dorsal side of the embryo before the dorsal lip is formed. Cells expressing goosecoid are fated to become pharyngeal endoderm, head mesoderm and notochord....

The Organizer and Beyond

Rehovot 76100 ganizer, positioned on the future dorsal side of the em-Israel bryo, can be viewed as an array of distinct secreted inhibitors that pattern the embryo by antagonizing the activity of ventralizing factors (BMPs and Wnts). Studies In 1924 Hans Spemann and Hilde Mangold carried out in Xenopus have uncovered an amazing diversity of in-an experiment that revolutionized the field of dev...
