μFFE device operation Liquid-electrode microchip free-flow electrophoresis (μFFE) devices were used83. Briefly, fluids were introduced to the device by PTFE tubing, 0.012″ inner diameter × 0.030″ outer diameter (Cole-Parmer) from glass syringes (Gas Tight, Hamilton) driven by syringe pumps...
We can do this in one pivot table operation too! From pandas, we'll call the pivot_table() method and set the following arguments: data to be our DataFrame df_tips index to be ['day', 'time'] since we want to aggregate by both of those columns so each row represents a unique ...
Don't understand why "operation writes a value happens before an operation that reads that value" in chapter 5.3.1 in <C++ Concurrency in action> I currently read about "C++ Concurrency in action", in the memory model part (Chapter 5). In chapter 5.3.1, the author writes: Leaving ...
Pandas: select rows if a specific column satisfies a certain condition Say I have this dataframe df: Say you want to select all rows which column C is >1. If I do this: I only obtain True or False in the resulting df. Instead, in the example given I want this result: ......
