Comparison of Phenotypes and Transcriptomes of Mouse Skin-Derived Precursors and Dermal Mesenchymal Stem Cells

The document from 2019 describes a search scheme called SMRI for retrieving encrypted full-text data from large datasets in cloud storage. It uses Simhash for dimensionality reduction to create an index, an improved secure k-nearest neighbor algorithm for encryption, and a B+ tree index for organizing data. The retrieval process involves a "filter-refine" strategy to efficiently find the top-k results with reduced computational complexity. The scheme is shown to be more efficient and less complex than existing methods, making it suitable for fast and secure data retrieval.
