  • Publication number: 20140136540
    Abstract: A system and method of determining the level of diversity for a search query are described. Distances between leaf categories in a hierarchical category tree are determined using co-click counts between the leaf categories for a query. Coordinate representations of the leaf categories are determined using the distances between the leaf categories. A diversity score for the query is determined using the coordinate representations. The diversity score represents a degree of variability in what different users find relevant to the query. In some embodiments, determining distances between leaf categories comprises determining the distances using a normalization of the co-click counts that uses co-impression counts between the leaf categories for the query. In some embodiments, a manifold learning algorithm is used to determine the coordinate representations. In some embodiments, multi-dimensional scaling is used to determine the coordinate representations.

  • Publication number: 20130273261
    Abstract: Methods of increasing an energy density of an energy storage device involve increasing the capacitance of the energy storage device by depositing a material into a porous structure of the energy storage device using an atomic layer deposition process, by performing a procedure designed to increase a distance to which an electrolyte penetrates within channels of the porous structure, or by placing a dielectric material into the porous structure. Another method involves annealing the energy storage device in order to cause an electrically conductive substance to diffuse to a surface of the structure and form an electrically conductive layer thereon. Another method of increasing energy density involves increasing the breakdown voltage and another method involves forming a pseudocapacitor. A method of increasing an achievable power output of an energy storage device involves depositing an electrically conductive material into the porous structure.

  • Patent number: 8029921
    Abstract: A semiconductor device including a ferrite layer, a widebandgap semiconductor material layer, and a buffer layer. The buffer layer comprises an interweaving of MgO and BaM. In addition the buffer layer allows a gradual reduction of the interfacial stress, and mediates the strain between a silicon substrate and a ferrite layer of the device. In addition, the buffer layer allows for high crystal alignment resulting in high crystal quality and thereby producing a low microwave loss semiconductor device. The buffer layer also minimizes chemical interdiffusion of atoms between the substrate and the ferrite layer.

  • Patent number: 7928268
    Abstract: The present invention relates to a process for producing a 2-fluoro-6-halophenol as an intermediate; a process for producing a 2-alkoxy-3-fluorophenol and further a 1,2-dialkoxy-3-fluorobenzene from the 2-fluoro-6-halophenol; a second process for producing a 1,2-dialkoxy-3-fluorobenzene from the 2-fluoro-6-halophenol; and a 2-alkoxy-3-fluorophenol. The 2-fluoro-6-halophenol can be obtained using a 2-fluorophenol as a starting material and through a sulfonation reaction, a halogenation reaction, and a deprotection reaction. The 2-fluoro-6-halophenol is alkyl-etherified, and subsequently the halogen atom is converted into a hydroxyl group to obtain the 2-alkoxy-3-fluorophenol, which is further alkyl-etherified to thereby obtain the 1,2-dialkoxy-3-fluorobenzene. Alternatively, a 1,2-dialkoxy-3-fluorobenzene is also obtained by converting the halogen atom of the 2-fluoro-6-halophenol into a hydroxyl group to thereby form 3-fluorocatechol and subsequently alkyl-etherifying two hydroxyl groups thereof.
