以下函数已被编写可以利用future 框架，如果设置适当的 plan，将进行并行。 例如，要运行并行版本，您只需要设置future 并照常调用 FindMarkers () 功能。 这里，我们将执行一个简单的比较，比较有和没有并行运行的时间差异。 请注意，虽然我们预计使用并行策略将减少上述函数的运行时间，但这种减少的幅度将取决于许多因素（例如数据集的大小、线程数、系统的规格、future框架等）。 以下基准是在运行 Ubuntu 16.04.5 LTS 的计算机上执行的，配置是 Intel (R) Core (TM) …

The 4 R's provides an ecologically sound and environmentally friendly approach to minimizing and managing waste and waste streams. The 4 R's approach attacks a waste stream in a logical and methodical method by taking steps to sequentially Reduce, Reuse, Recycle and Recover a waste stream into incremental fractions.

THE FOUR R'S Good waste management follows the 4 Rs: Reduce, Reuse, Recycle and Recover, as well as avoiding illegal dumping and littering. Did you know that the 4 Rs can help us to find better ways to
