Study on lightweight strategies for L-YOLO algorithm in road object detection.

With the increasing complexity of urban traffic, object detection has become critical in autonomous driving and intelligent traffic management. The demand for real-time, efficient object detection systems is growing. However, traditional algorithms often suffer from large parameter sizes and high computational costs, limiting their applicability in resource-constrained environments.

[Application of electro-acupuncture-anesthesia device in brachiplex nerve blocking].

Objective: To investigate the effect of electro-acupuncture-anesthesia device (EAAD) as an auxiliary localizing method for brachiplex nerve blocking.

Methods: One hundred and twenty patients scheduled for operation in upper limbs were randomly divided into group A and group B, 60 in each group. Bupivacaine 25 ml (0.
