Background Perioperative blood loss and early recovery are major concerns when elderly patients undergo total hip arthroplasty (THA) for femoral neck fractures. The minimally invasive transpiriformis approach (MIS-TPA), which preserves posterior soft-tissue structures, has recent…
Background Despite the growing burden of prostate cancer in China and the widespread use of androgen deprivation therapy (ADT), no validated disease-specific instrument has been used to systematically characterize symptom clusters and their impact on quality of life (QoL) in this…
Objective To systematically evaluate the quality and internal consistency of the long-term care insurance (LTCI) policy documents in five pilot cities of Guangxi Zhuang Autonomous Region, explore the allocation structure of policy instruments and the interaction pattern of stakeh…
Recommendation systems, from traditional multi-stage to recent unified generative architectures, face challenges in incorporating diverse contextual signals, such as trending topics, breaking news, cultural events, and cross-surface user activities, into their ranking pipelines.…
The decline of human balance control due to aging and pathological conditions increases fall risk, a major concern in geriatric care and rehabilitation. Gait training is essential for balance recovery, enhancing walking ability and postural control. However, existing overground r…
Merge with Motion Vector Difference (MMVD) is a key coding tool in Versatile Video Coding for improving motion prediction accuracy. However, its exhaustive search strategy imposes a significant computational burden on the encoder. To address this issue, we propose a novel fast MM…
Industrial recommendation systems serve billions of users through a multi-stage funnel -- retrieval, early-stage ranking, and re-ranking -- where the final re-ranking step disproportionately shapes user engagement and downstream performance, particularly for carousel and grid dis…
