Crosslinkable, polyaromatic, polyether or polyester oligomers can have glass transition temperatures above 900.degree. F. while exhibiting desirable toughness for aerospace applications and ease of processing. A plurality (i.e. three or more) of generally linear aryl arms extend outwardly like spokes from a central aromatic hub through ether or ester linkages. Each spoke usually includes electronegative linkages, and is capped with one or two crosslinking functionalities (i.e. unsaturated hydroc...

An agent generates a multidimensional database including file object characteristics, also known as a datacube, on each of a plurality of hosts, and employs a common server for aggregating each of the smaller datacubes into a collective datacube, or multicube, representative of all of the smaller datacubes from each of the hosts. Each individual host, therefore, contributes only a portion of the larger multicube and therefore processes and stores only the multicube portion of the file objects it...

This invention provides an advanced platform for the analysis of biological data that emphasizes pathway mapping and relationship inference based upon data acquired from multiple diverse sources. The platform employs a bioinformatic system that integrates data from the diverse sources, connecting related genes and proteins and inferring biological functions in the context of global cellular processes.

High performance polyester sulfone oligomers are prepared for aerospace applications by condensing mono- or difunctional crosslinkable end caps (i.e. unsaturated hydrocarbons having one or two crosslinking sites) with dicarboxylic acid halides and dialcohols (i.e. diols). Multidimensional oligomers have an aromatic hub from which the polyester chains radiate. Blends of the linear and multidimensional oligomers can be made using compatible, non-crosslinking polymers. Prepregs and composites are f...

A hierarchial bus structure having at least three dimensions provides improved interconnect flexibility between nodes located on one or more levels of the structure. Nodes are defined on at least first and second "horizontal" (or "H") rings, the rings being coupled by at least one "vertical" (or "V") ring. Each node is identified in terms of its (H,V) coordinates in the hierarchial interconnect structure, and an M-dimensional structure will provide an M-way multiplex unit at each node. For an M=...

The present method provides methods and apparatus for separating proteins using a series of electrophoretic methods that utilize controlled fractionation and labeling techniques to resolve mixtures of proteins. The samples for each electrophoretic method other than the initial method, contain only a subset of proteins resolved in the preceding method. The methods can be used in a variety of different applications including, creating proteomic databases, comparative expression studies, diagnostic...

A computer-based method and system for performing header filtering of data is presented The method comprises compressing the header of a data packet to obtain a header signature and determining if the header signature matches a known header signature. If the header signature is determined to have a match, then the header signature is identified as a known header signature. A header signature may be generated using a multidimensional data compression algorithm. A compression algorithm comprises o...

In a multidimensional database, an aggregation operation is performed in an optimal manner by storing the values included in the/aggregation operation on the same disk page. A sparsity manager determines aggregate values that are computed from other data values during the aggregation operation. Each aggregate value is associated with one or more data values that are used during the aggregation operation to compute the aggregate value. The sparsity manager stores the associated data values in pro...

A method and system for processing multidimensional data. A method of forming multiresolution representations of data includes partitioning the data in a first dimension at a first rate, and partitioning the data in a second dimension at a second rate, wherein the first rate is not equal to the second rate. In one embodiment, the first rate is set to one, and the second rate is computed as the ratio of a smoothness estimate of the first dimension data and a smoothness estimate of the second dime...
