Development and Validation of Daping Orthopedics Operative Risk Scoring System for Geriatric Hip Fracture ( DOORS ‐ GHF ) for Predicting Postoperative Outcomes in Geriatric Hip Fracture Patients: A Multicenter Retrospective Comparative Study

ABSTRACT Objective With China's accelerating population aging, geriatric hip fractures pose a growing clinical challenge. High comorbidity burden and diminished physiological reserve drive elevated postoperative complication and mortality risks in this population. However, most e...

Controlled Bidirectional Remote Implementation of Arbitrary Unknown Single-Qubit Operations via a High-Dimensional Quantum Channel

Consider two remote laboratories: Alice holds an unknown input |ξ⟩ and a private single-qubit unitary UA, while Bob holds |η⟩ and UB. We present an exact local-operations-and-classical-communication protocol that produces UB|ξ⟩ at Alice’s site and UA|η⟩ at Bob’s site only after t...
