Abstract: A method for forming a substrate comprising nanometer-scale pillars or cones that project from the surface of the substrate is disclosed. The method enables control over physical characteristics of the projections including diameter, sidewall angle, and tip shape. The method further enables control over the arrangement of the projections including characteristics such as center-to-center spacing and separation distance.

Abstract: An optoelectronic device comprising an optically active layer that includes a plurality of domes is presented. The plurality of domes is arrayed in two dimensions having a periodicity in each dimension that is less than or comparable with the shortest wavelength in a spectral range of interest. By virtue of the plurality of domes, the optoelectronic device achieves high performance. A solar cell having high energy-conversion efficiency, improved absorption over the spectral range of interest, and an improved acceptance angle is presented as an exemplary device.

Abstract: A method and system for searching an electronic map. The method includes the steps of: receiving a query entered by a user for searching the electronic map; extracting place names in the query; extracting in web pages searched on a computer network co-occurrence place names that co-occurred with the place names; selecting extension place names from the co-occurrence place names, thereby obtaining a set of extension place names; generating a set of queries, wherein the set of queries includes the query entered by the user, and includes a query obtained by replacing the place names in the query entered by the user with each extension place name in the set of extension place names respectively; and sending the set of queries to a map search engine.

Abstract: A user comment processing method and system and an information retrieval method and system. The user comment processing method includes the steps of: receiving objective data of a feature of a product or service and user comments on the product or service; identifying user comments associated with the feature of the product or service from the user comments on the product or service; identifying the opinion facet in the user comments associated with the feature of the product or service; establishing association-relationship between the opinion facet and the objective data of the corresponding feature of the product or service, and calculating an occurrence frequency of the opinion facet associated with the objective data; and creating an association rule of the opinion facet and the objective data according to the association-relationship and the occurrence frequency of the opinion facet associated with the objective data.

Abstract: The invention relates to methods for extending a primer or a pair of primers in low-temperature cycle DNA amplification for cycle sequencing and PCR. In particular, the methods contemplate the combined use of moderately thermostable DNA polymerases in the presence of a low concentration of glycerol or ethylene glycol, or the mixtures thereof, as an agent to reduce the melting temperature of DNA (that is, the temperature at which the double-strands of DNA are denatured). Predistributed reaction mixtures of a high-fidelity and high processivity DNA polymerase stable at room temperature for several weeks in ready-to-use kits are also contemplated by the invention.
