    • Methods are provided for the preparation of a sample using a digital microfluidic platform and the optional subsequent mass analysis of an extracted analyte. A sample is dried, optionally on a solid phase support, and contacted with digital microfluidic array. An analyte present within the dried sample is extracted into an extraction solvent by electrically addressing the digital microfluidic array to transport a droplet of extraction solvent to the dried sample spot. The extracted sample may be dried and subsequently processed on the digital microfluidic array for derivatization. The digital microfluidic device may further include an integrated microfluidic channel having an output aperture, and the method may further include contacting a droplet containing extracted analyte with the microfluidic channel and applying a suitable electric field for generating nano-electrospray, thereby enabling the device to be directly interfaced with a mass analysis device.

    • Methods and systems are provided for optimally trading off replication overhead and consistency levels in distributed data replication where nodes are organized in a hierarchy. The root node has the original data that need to be replicated at all other nodes, and the replicated copies have a freshness threshold that must be satisfied. The data are propagated through periodic updates in the hierarchy. Each node periodically sends data to its child nodes. Given the freshness threshold, an algorithm and its distributed protocol can determine the optimal update period for each link of the hierarchy such that the freshness threshold is satisfied for every node and the overall replication overhead is minimized. The systems and methods can be used in any scenario where replicated data have consistency requirements, such as in a replicate overlay assisted resource discovery system.
    • 提供了方法和系统,用于最佳地折中分布式数据复制中的复制开销和一致性级别,其中节点被组织在层次结构中。 根节点具有需要在所有其他节点进行复制的原始数据,并且复制副本具有必须满足的新鲜度阈值。 数据通过层次结构中的定期更新进行传播。 每个节点周期性地向其子节点发送数据。 给定新鲜度阈值,算法及其分布式协议可以确定层次结构的每个链路的最佳更新周期,使得每个节点满足新鲜度阈值,并将整体复制开销最小化。 系统和方法可以在复制数据具有一致性要求的任何情况下使用,例如在复制覆盖辅助资源发现系统中。
