Abstract: The subject invention relates to the identification of genes involved in the desaturation of polyunsaturated fatty acids at carbon 5 (i.e., “&Dgr;5-desaturase”) and at carbon 6 (i.e., “&Dgr;6-desaturase”) and to uses thereof. In particular, &Dgr;5-desaturase may be utilized, for example, in the conversion of dihomo-&ggr; -linolenic acid (DGLA) to arachidonic acid (AA) and in the conversion of 20:4n-3 to eicosapentaenoic acid (EPA). Delta-6 desaturase may be used, for example, in the conversion of linoleic (LA) to &ggr;-linolenic acid (GLA). AA or polyunsaturated fatty acids produced therefrom may be added to pharmaceutical compositions, nutritional compositions, animal feeds, as well as other products such as cosmetics.

Abstract: A transistor gate dielectric structure includes an oxide layer formed on a substrate, a superjacent nitride layer and a transition layer interposed therebetween. The presence of the transition layer alleviates stress between the nitride and oxide layers and minimizes any charge trapping sites between the nitride and oxide layers. The transition layer includes both nitrogen and oxygen as components. The method for forming the structure includes forming the transition layer using a remote nitridation reactor at a sufficiently low temperature such that virtually no nitrogen reaches the interface formed between the oxide layer and the substrate. The oxide layer/substrate interface is relatively pristine and defect-free. In an exemplary embodiment, the oxide layer may be a graded structure formed using two distinct processing operations, a first operation at a relatively low temperature and a final operation at a temperature above the viscoelastic temperature of the oxide film.

Abstract: An exemplary embodiment of the invention is a method and apparatus for delaying the start of an array built-in self-test (ABIST) until after the ABIST memory arrays have been started. The length of the delay is determined by the value in a programmable delay located on the integrated circuit. The initiation of the ABIST test is delayed by the time specified in the programmable delay.

Abstract: The present invention relates to a general-purpose programmable packet-processing platform for accelerating network infrastructure applications which have been structured so as to separate the stages of classification and action. Network packet classification, execution of actions upon those packets, management of buffer flow, encryption services, and management of Network Interface Controllers are accelerated through the use of a multiplicity of specialized modules. A language interface is defined for specifying both stateless and stateful classification of packets and to associate actions with classification results in order to efficiently utilize these specialized modules.

Abstract: The subject invention relates to the identification of four genes involved in the elongation of polyunsaturated acids (i.e., “elongases”) and to uses thereof. Two of these genes are also involved in the elongation of monounsaturated fatty acids. In particular, elongase is utilized in the conversion of gamma linolenic acid (GLA) to dihomogamma linolenic acid (DGLA) and in the conversion of DGLA or 20:4n-3 to eicosapentaenoic acid (EPA). DGLA may be utilized in the production of polyunsaturated fatty acids, such as arachidonic acid (AA), docosahexaenoic acid (DHA), EPA, adrenic acid, &ohgr;6-docosapentaenoic acid or &ohgr;3-docosapentaenoic acid which may be added to pharmaceutical compositions, nutritional compositions, animal feeds, as well as other products such as cosmetics.

Abstract: Tantalum and niobium aluminum-doped hydrated mixed metal oxide sols may be made by a process comprising combining a first metal compound aluminum alkoxide, with a second metal compound selected from the group consisting of niobium alkoxide and tantalum alkoxide, and mixtures thereof to provide a substantially water-free precursor and combining the precursor with a ketone to provide a hydrated mixed metal oxide sol, wherein the ketone is substantially free of water. The sol may then be processed to obtain thin films, fibers, crystals (both micro- and meso-porous), powders and macroscopic objects and to provide mixed metal oxide that may be used in a variety of components of integrated circuits.

Abstract: Systems and methods for enlarging selectable content. Content that includes selectable items is displayed on a display device through a user interface. When an item is selected, the item is enlarged such that the selected item is more easily viewed. If the item includes text, the text is more legible because it has been enlarged. Other items included in the content that are not currently selected are not enlarged or modified. When a new item is selected, the new item is enlarged and the previously selected item returns to an unselected size and is no longer enlarged.

Abstract: Displaying a video stream when constrained by system memory and connection bandwidth. When the resources and/or memory of a client are insufficient to decode and process a video stream, the client only decodes and processes key frames of the video stream. The other frames are discarded by the client. By decoding and processing key frames, the memory and resource requirements of the video stream are reduced. The client is also able to negotiate with the video stream source such that only key frames are downloaded. Bandwidth limitations can thus be accommodated because downloading only key frames requires less bandwidth.

Abstract: The subject invention relates to the identification of several genes involved in the elongation of polyunsaturated acids (i.e., “elongases”) and to uses thereof. At least two of these genes are also involved in the elongation of monounsaturated fatty acids. In particular, elongase is utilized in the conversion of gamma linolenic acid (GLA) to dihomogamma linolenic acid (DGLA) and in the conversion of AA to adrenic acid (ADA), or eicosapentaenoic acid (EPA) to &ohgr;3-docosapentaenoic acid (DPA).

Abstract: A voice networking switching (VNS) appliance and methods for its use are disclosed. In a preferred embodiment, the VNS is an adjunct processor attached to a WAN node and software-configured to provide switching services for private network PBXs and PSTN central offices that have trunks ported to a WAN node. The switching services offered by the VNS allows PBXs to establish voice and data connections between each other, as well as with the PSTN, dynamically via Switched Virtual Circuits (SVCs) that are routed directly across a WAN. This arrangement eliminates the need for an extensive mesh of PVCs or leased “tie lines” carrying voice and data traffic between ported trunks across the WAN. Furthermore, private network end users can connect to the PSTN without their PBX having a direct connection to the PSTN. Likewise, a private network connection to a PSTN central office can be established in a location where no PBX is present.

Abstract: A package substrate having sides, which is formed of multiple non electrically conductive layers laminated together. Each of the multiple non electrically conductive layers is formed of a first lamina and a second lamina bonded together in a resin matrix. The first lamina is formed of woven fibers having a first warp. The first warp of the first lamina is disposed at a positive orientation of a first angle from the sides of the package substrate, where the first angle is neither zero degrees nor ninety degrees. The second lamina is also formed of woven fibers, having a second warp. The second warp of the second lamina is disposed at a negative orientation of the first angle from the sides of the package substrate. Electrically conductive layers are dispersed between different ones of the multiple non electrically conductive layers, with electrical connections dispersed between different ones of the electrically conductive layers.
