Comparison of the effects of Valsalva maneuver, EMLA cream, and the combination of both in relieving pain of needle insertion on totally implantable access port: A randomized controlled study.

Background: Totally implantable access port (TIAP) is a subcutaneously implanted, long-term infusion device that is widely used in oncology patients. However, multiple needle insertions into TIAP may lead to pain, anxiety, and dread in patients. This study aimed to compare the effectiveness of Valsalva maneuver, eutectic mixture of local anesthetics (EMLA) cream, and the combination of both in relieving pain of cannulations on TIAP.

Driver Intent-Based Intersection Autonomous Driving Collision Avoidance Reinforcement Learning Algorithm.

With the rapid development of artificial intelligent technology, the deep learning method is widely applied to predict human driving intentions due to its relative accuracy of prediction, which is one of critical links for security guarantee in the distributed, mixed driving scenario. In order to sense the intention of human-driven vehicles and reduce the self-driving collision avoidance rate, an improved intention prediction method for human-driving vehicles based on unsupervised, deep inverse reinforcement learning is proposed. Firstly, a contrast discriminator module was proposed to extract richer features.
