Talvez deva tentar algumas variações de ortografia:
retrieval process » retrieval models (Expandir a busca), removal process (Expandir a busca)
dense retrieval » phase retrieval (Expandir a busca), dna retrieval (Expandir a busca), depth retrieval (Expandir a busca)
decrease after » increase after (Expandir a busca), disease after (Expandir a busca)
after decrease » faster decrease (Expandir a busca), after deceased (Expandir a busca), litter decrease (Expandir a busca)
decrease toc » decrease of (Expandir a busca), decrease the (Expandir a busca), decreased to (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)
toc dense » to dense (Expandir a busca), of dense (Expandir a busca), on dense (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease toc dense retrieval process ) OR ( decrease in decrease after decrease ))~.
