Abstract: A method for operating a graph database, including receiving, by a computer system, a query to a particular graph database, the query identifying a plurality of vertices of the particular graph database. The method further includes performing, by the computer system, hash operations on two or more of the plurality of vertices to generate respective hash values and dividing, using the respective hash values, the query into a plurality of sub-queries, each corresponding to a subset of the plurality of vertices. The method also includes sending, by the computer system, ones of the plurality of sub-queries to a plurality of database repositories for the particular graph database.

Abstract: A method for masking sensitive data based on image recognition comprises: extracting initial image features of a to-be-processed image in multiple dimensions of features; reducing dimensions for the initial image features in the multiple dimensions of features, to obtain image features of the to-be-processed image in at least one dimension of sensitive data masking; identifying sensitive features of the to-be-processed image based on the image features in the at least one dimension of sensitive data masking; masking the sensitive data for the sensitive features of the to-be-processed image. The method for masking sensitive data based on image recognition realizes the sensitive data masking for images based on image recognition, and the efficiency of sensitive data masking is relatively high.

Abstract: A new composition of nanosized bagasse fibers has been made by a method which reduces the sugarcane bagasse fibers to nano-sized particles while retaining the natural components of the bagasse. The resulting bagasse particles were shown to be effective as a nutritional supplement in a mouse model to aid in glucose control and body weight. Using the bagasse nanofibers, the addition of 5 to 10% fiber did not change the color or texture of food products. Moreover, the bagasse powder has a natural color and absorbs color evenly so that it could be used as a natural foundation material for cosmetic products.

Abstract: A method to decrease the surface roughness of exposed PMMA surfaces has been discovered. PMMA surface roughness was decreased by a post-exposure heat treatment of less than 70° C. The optimum post-exposure heat treatment to produce a PMMA microstructures with a smooth surface was found to be about 60° C. for about 30 min. The structural features of post-exposure heat-treated PMMA patterns were not statistically different from otherwise identical features of untreated PMMA patterns. This method produces a smoother PMMA structure that may then optionally be glued on a substrate or that may be assembled with other PMMA structures into a three-dimensional or multilayer microstructure.

Abstract: A skate cart includes a board with a front wheel and a rear wheel. A handlebar stem is pivotally connected to a connection port extending from a front end of the board and the front wheel is connected to the handlebar stem. The connection port has two lugs and a lower end of the handlebar stem is engaged between the two lugs. A rod is movably inserted through one of the lugs and a passage in the handlebar stem. When pulling the rod out from the passage in the handlebar stem, the handlebar stem is pivotable relative to the board.
