Talvez deva tentar algumas variações de ortografia:
the preprocessing » the processing (Expandir a busca), their processing (Expandir a busca), image preprocessing (Expandir a busca)
decreased fear » decreased heart (Expandir a busca), decreased mean (Expandir a busca), decreased after (Expandir a busca)
fear decrease » break decrease (Expandir a busca), merr decreases (Expandir a busca), can decrease (Expandir a busca)
decrease the » decreases the (Expandir a busca), decrease of (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decreased fear decrease the preprocessing ) OR ( decrease in decrease NOT decrease ))~.
