Abstract: A cutting tool assembly having a tool holder and a cutting tool. The cutting tool has a shank that is matingly received within an axial bore in the lower end of the tool holder. The shank includes an eccentrically-shaped driver portion. The tool holder's axial bore includes an enlarged eccentrically-shaped drive opening which is complementary in shape to, but slightly larger than, the driver portion. When the shank is inserted into the axial bore, the driver portion and drive opening are aligned allowing the cutting tool to be partially rotated relative to the tool holder. This partial rotation abuts a portion of the eccentric driver portion against the drive opening wall to provide rigid support of the cutting tool against further rotation as the tool assembly cuts. A cammed fastener releasably interlocks the partially rotated cutting tool within the tool holder.

Abstract: A method and system for generating authority score ranking to a plurality of linked documents is provided. The method uses a linear or nonlinear authority score function that takes in the feature vectors of the documents and a set of parameters. The system generates feature vectors for the documents. The method updates the parameters for each of the documents, for which an update on a document is based on the score of the document, the scores of one or more predecessors of the document, and some scalar signals. Finally, the authority score assigned to a document is computed from the score function using the feature vector of the document and the set of parameters. The method and system is particularly useful in reducing memory requirement, improving computation efficiency, providing generalization among similar documents, and scaling with the size of databases for authority ranking of large corpuses of documents, such as ranking of web pages.

Abstract: HLTF, a SWI/SNF2 ATPase, has a role in replication of damaged DNA. We found that HLTF is able to reverse model replication forks, which depends on its double-stranded DNA translocase activity.   Furthermore, from analysis of isolated dual-labeled chromosomal fibers, we demonstrate that in vivo HLTF promotes the restart of replication forks blocked at DNA lesions. These findings indicate that HLTF can facilitate template switching for error-free damage bypass and support a role for HLTF in preventing mutagenesis and carcinogenesis, providing thereby for its potential tumor suppressor role.   The invention provides for methods for finding HLTF inhibitors and methods for identifying cytotoxic drugs effective in HLTF deficient tumors.

Abstract: A method and apparatus for reducing discharges into the atmosphere of mercury pollutants associated with dry process, precalciner cement manufacturing is shown. Raw feed meal used in cement production is heated in a special heating chamber to drive off volatile mercury pollutants, such as elemental mercury and mercury oxides. Preferably, the feed meal is heated to a temperature of at least 175° C. The gases that are driven off flow are then cooled to condense the mercury pollutants causing them to be adsorbed on carbon particles injected into the gas flow. The carbon particles containing the condensed mercury pollutants are then filtered out of gas flow, for example, using a fabric filter. The gas flow may be burned to destroy other volatile pollutants such as hydrocarbons and/or ammonia.
