Network topologies

QUESTION 1: If one of the links to a computer on a physical star topology is served, what will be the result? A. The entire network will stop working. B. The affected link and the adjacent network links will stop working. C. Only the affected link will stop working. D. Only the adjacent links will stop working. Answer: C In the star topology each computer is connected to a central point by a separate cable or wireless connection. Thus each computer has a dedicated link to the network central device and a break in the link between a particular computer...

The topology of central carbon metabolism ofAspergillus nigerwas identified and the metabolic network reconstruc-ted, by integrating genomic, biochemical and physiological information available for this microorganism and other related fungi. The reconstructed network may serve as a valuabledatabase for annotationof genes identified in future genome sequencing projects on aspergilli. Based on the metabolic reconstruction, a stoichiometric model was set up that includes 284metabolites and335reactions,...

In view of the increasing number of reported concentration oscillations in living cells, methods are needed that can identify the causes of these oscillations. These causes always derive from the influences that concentrations have on reaction rates. The influences reach over many molecular reaction steps and are defined by the detailed molecular topology of the network. So-called
autoinfluence paths, which quantify the influence of one molecular species upon itself through a particular path through the network, can have positive or negative values....

Patterns of protein interactions are organized around complex heterogene-ous networks. Their architecture has been suggested to be of relevance in understanding the interactome and its functional organization, which per-vades cellular robustness. Transcription factors are particularly relevant in this context, given their central role in gene regulation.
