University of Oklahoma researchers have investigated a new variant of multidimensional hypercubes as computational elements of nanocomputers: the "M-hypercube," which could provide a higher-dimensional layout to support three-dimensional integrated circuits and the quantum properties of nanocomputers.The unique structure of hypercubes provides a massively parallel, distributed processing architecture with simple, robust communication linkages, able to count single electrons, and allow for parallel computing, reversibility, locality, and a three-dimensional architecture.M-hypercubes contain two types of nodes: state nodes, which are embedded on the vertices of the M-hypercubes; and transmission nodes, which are embedded in the middle of the links between state nodes. Each node can be turned on or off; the transmission nodes can isolate parts of the cube from other parts when in the off state.

With search engine privacy growing as a hotbutton issue, Microsoft announced Sunday that it is instituting an "enhanced set of privacy principles" for its Live Search and online-advertising technologies. The privacy measures parallel some of those taken recently by Google and Ask.com.
When a user searches on Live Search, some information, such as a machine-identifiable piece of software known as a "cookie," is retained to assist in targeted advertising. Microsoft's new privacy steps include setting an 18-month time limit on cookie IDs and other identifiers so that the data will become anonymous unless users opt in.
Microsoft's chief privacy strategist, Peter Cullen, said in a statement that it is "critical" for the company to evolve its privacy principles. He added that "keeping these issues as simple as possible for consumers is the best approach," so that, for instance, "anonymous should mean anonymous." Microsoft also asked that the search industry meet to set standards.
Unique Identifiers
Much of Microsoft's new privacy efforts revolve around unique identifiers, such as cookies. Matching up what you search with who you are is increasingly becoming a concern for privacy advocates. In 2006, for example, AOL researchers mistakenly posted data on some 650,000 searches. New York Times reporters were able to track down a single searcher on the basis of the posted information.
Microsoft said that when it begins to offer ads for third-party Web sites, it will let users opt out of behavioral targeting, which is pegged to "personal and unique" identifiers. Microsoft also said it will store Live Search query terms separately from any account information that identifies a registered user, to avoid the "unauthorized correlation of the data" by ers.
Microsoft sees privacy as "a potential advantage that can be played against Google," said Gartner analyst Andrew Frank. "If Microsoft can take the high ground," he said,. Microsoft Promotes Privacy in Search
Late this week, the Federal Reserve responded to concerns about liquidity in the markets by infusing cash into the banking system. Some on Wall Street want the Fed to do more. But, as NBR Washington Bureau Chief Darren Gersh reports, Bernanke's bank isn't eager to jump into its red cape and tights. Fed Strategy
