Abstract: Techniques are described herein for performing a flush operation for a write booster buffer of a memory system. The flush operation may include swapping valid blocks in the write booster buffer for invalid blocks in a storage space of the memory system. After swapping the blocks, the memory system may transfer the information from a first type of blocks that were formerly assigned to the write booster buffer to a second type of blocks in the storage space. In such a flush operation, space is made available in the write booster buffer with less latency than it would take to transfer information between blocks, thereby improving the performance of the write booster mode.

Abstract: Disclosed herein are methods and systems that use a photonic crystal (PC) for interference scattering microscopy. Incident light is directed onto a surface of the PC and couples into a photonic crystal guided resonance (PCGR) mode of the PC such that less than 1% of the incident light is transmitted through the PC as transmitted light. One or more particles adjacent to the surface of the PC scatter a portion of the light coupled into the PCGR mode as scattered light. An image comprising a pattern of constructive and destructive interference between the transmitted light and the scattered light is formed, and an image sensor may capture one or more image frames of the image. Imaging processing of the one or more image frames can be used to identify at least one scattering center corresponding to at least one particle of the one or more particles.

A new payment transaction that looks similar to a previously identified cluster of mostly fraudulent payment transactions, for example, may be higher risk.

A new event can be classified into a particular segment very quickly using feature table searching, which can allow for better decision making when a short timeframe is required (e.g. transaction processing, online advertising, etc.).
