Shenghui - 
Check charm decay electron cross section. 
Check low pT inclusive electron if have time.
Help on Run14 embedding if available.
Work on TPC NPE if embedding is not ready.

Long -
Check TMVA-BDT method with D0 tree sample.
Check preselection tuning.

Xiaolong - 
Start working on D0 with TPC only. 
Hybrid method: loop all global tracks for K/pi, if primary information is valid use primary momentum, otherwise use global track with a DCA cut (need study).
