Talvez deva tentar algumas variações de ortografia:
sampling python » sampling method (Expandir a busca), sampling position (Expandir a busca), sampling methods (Expandir a busca)
based sampling » and sampling (Expandir a busca), blood sampling (Expandir a busca), based sample (Expandir a busca)
decrease based » decreased base (Expandir a busca), decrease blood (Expandir a busca)
decrease with » decreases with (Expandir a busca), increase with (Expandir a busca), decrease in (Expandir a busca)
with decrease » with decreased (Expandir a busca), with deceased (Expandir a busca), with increase (Expandir a busca)
python based » action based (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease with decrease based program ) OR ( python based sampling python programming ))~.
