Abstract: Methods and cells for producing scattered branched-chain fatty acids are provided. For example, the invention provides a method for producing branched-chain fatty acid comprising a methyl on one or more even number carbons. The method comprises culturing a cell comprising an exogenous or overexpressed polynucleotide comprising a nucleic acid sequence encoding a polypeptide that catalyzes the conversion of propionyl-CoA to methylmalonyl-CoA and/or an exogenous or overexpressed polynucleotide comprising a nucleic acid sequence encoding a polypeptide that catalyzes the conversion of succinyl-CoA to methylmalonyl-CoA, under conditions allowing expression of the polynucleotide(s) and production of branched-chain fatty acid. The cell produces more branched-chain fatty acid comprising a methyl on one or more even number carbons than an otherwise similar cell that does not comprise the polynucleotide(s). A cell that produces branched-chain fatty acid and the branched-chain fatty acid also are provided.

Abstract: A method of forming a well-anchored carbon nanotube (CNT) array, as well as thermal interfaces that make use of CNT arrays to provide very high thermal contact conductance. A thermal interface is formed between two bodies by depositing a continuous array of carbon nanotubes on a first of the bodies so that, on mating the bodies, the continuous array is between surface portions of the first and second bodies. The thermal interface preferably includes a multilayer anchoring structure that promotes anchoring of the continuous array of carbon nanotubes to the first body. The anchoring structure includes a titanium bond layer contacting the surface portion of the first body, and an outermost layer with nickel or iron catalytic particles from which the continuous array of carbon nanotubes are nucleated and grown. Additional thermal interface materials (TIM's) can be used in combination with the continuous array of carbon nanotubes.

Abstract: Architecture for extracting document information from documents received as search results based on a query string, and computing an edit distance between the data string and the query string. The edit distance is employed in determining relevance of the document as part of result ranking by detecting near-matches of a whole query or part of the query. The edit distance evaluates how close the query string is to a given data stream that includes document information such as TAUC (title, anchor text, URL, clicks) information, etc. The architecture includes the index-time splitting of compound terms in the URL to allow the more effective discovery of query terms. Additionally, index-time filtering of anchor text is utilized to find the top N anchors of one or more of the document results. The TAUC information can be input to a neural network (e.g., 2-layer) to improve relevance metrics for ranking the search results.

Abstract: Systems and methods are provided for implementing error identification and evaluation for a Reed-Solomon (RS) error-correction code (ECC) system. The BMA algorithm and/or list decoding may produce one or more error locator polynomials that are related to a decision-codeword. An accelerated Chien search can be used to more quickly evaluate the one or more error locator polynomial. If the accelerated Chien search identifies a valid error locator polynomial, a normal Chien search can be used to identify error locations, and Forney's algorithm or an equivalent technique can be used to evaluate the error values. A RS ECC decoder can include a computation circuit that evaluates an error locator polynomial or an error evaluator polynomial. The computation circuit can include computation components that receive the coefficients of the polynomials.
