LongRCA Bench: Root-Cause Localization in Long-Horizon Agent Trajectories

In long agent executions, an early error can persist through later actions and checks, while evidence needed to trace its origin is dispersed across the history. Short histories offer limited tests of recovering error origins across substantial subsequent execution. We introduce LongRCA Bench: 1,140 complete failed tra...

Effect of early local cold compression therapy combined with rehabilitation exercises on local swelling and joint function recovery in patients with periarticular ankle fractures

Early local cold compression therapy combined with rehabilitation exercises can significantly alleviate ankle swelling and pain, improve ankle function as assessed by the AOFAS Ankle-Hindfoot Scale, and accelerate the recovery of ankle ROM in patients with periarticular ankle fractures.

This work introduces LongRCA Bench, comprising 1,140 failed trajectories across five domains without injected errors, and presents Root-Cause Trajectory Attribution (RCTA), a training-free method that retrieves candidate error steps from segment summaries and traces them to available earlier handoff instructions.
