Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Science is becoming more and more international breaking down walls in its’ pursuit for high impact. Despite geographical location and distance are still standing as major barriers for scientific collaboration, little is known whether high impact collaborations are similarly constrained by geography like collaborations with an average impact. To address this question, we analyze Web of Science data on international collaboration between global leader cities in science production. We report increasing intensity of international city-city collaboration and find that average distance of collaboration of the strongest connections has slightly increased but distance-decay has remained stable over the last three decades. However, high impact collaborations span large distances by following similar distance decay. This finding suggests that a ' .
