Talvez deva tentar algumas variações de ortografia:
observed programa » observer program (Expandir a busca), server programa (Expandir a busca)
decay observed » data observed (Expandir a busca), newly observed (Expandir a busca), directly observed (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
python based » action based (Expandir a busca)
based python » based path (Expandir a busca), and python (Expandir a busca), gate python (Expandir a busca)
code decay » mode decay (Expandir a busca), body decay (Expandir a busca), golden decay (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code decay observed programa ) OR ( python based python python programming ))~.
