    摘要: This invention relates to a system and methods for determining the placement of an object in a distributed key-value store by mapping the object to nodes in multidimensional hyperspace. A search function supports efficient object retrieval, even when the search query requests multiple objects and specifies them through non-primary keys. In response to a search query, the search is translated into hyperregions in the hyperspace to determine the set of nodes that hold the queried data object. The number of contacted nodes and the number of scanned objects are significantly reduced in comparison to prior art techniques.

    摘要: The present invention provides a device for detecting the presence of an analyte, wherein said analyte is a microorganism marker gas. The device comprises a sample chamber having a fluid inlet port for the influx of the microorganism marker gas; a fluid concentrator in flow communication with the sample chamber, wherein the fluid concentrator has an absorbent material capable of absorbing the microorganism marker gas and thereafter releasing a concentrated microorganism marker gas; and an array of sensors in fluid communication with the concentrated microorganism marker gas. The sensor array detects and identifies the marker gas upon its release from fluid concentrate.
