Abstract:
Updating a personalized web page by identifying characteristic features and an information sample from an input, in which the input specifies a web site that provides the information sample. When an update is required by a user-specified frequency, corresponding contents of the web site are determined based on the characteristic features. If the corresponding contents are highly relevant to the information sample, the corresponding contents are extracted, and the personalized web page is updated with the corresponding contents.
Abstract:
The present invention is a method for providing light onto a thin light transparent substrate comprising the steps of passing noncoherent light through a fiber optic line light guide to produce line light; and impinging the line light onto the edge of the substrate to produce an evanescent planar wave on the surface of the substrate. This method is specifically useful in reading fluorescent signals from microarrays placed on a light transparent substrate.

Abstract:
The present invention provides a method for engraving desired irreproducible patterns on the surface of gemstones including diamond by the use of an energetic ion beam. The pattern has a characteristic topological texture, which is irreproducible even using the same ion beam to engrave onto the same location of the same diamond.
Abstract:
A truncated glucanase with an improved thermal stability and a higher specific enzymatic activity than the wild-type enzyme. The truncated glucanase is obtained by removing a number of amino acid residues from the C-terminal of the wild-type 1,3-1,4-β-D-glucanase of Fibrobacter succinogenes. The removal of the C-terminal amino acid residues can be conducted at the genetic level by modifying the gene encoding for the wild type enzyme using, for example, a PCR-based method. Or, it can also be conducted at the protein level by first producing the wild-type enzyme protein and then subjecting the wild-type protein to certain protease action to remove a portion of its C-terminal.
