Large language models have recently attracted significant attention due to their impressive performance on a variety of tasks. ChatGPT developed by OpenAI is one such implementation of a large, pre-trained language model that has gained immense popularity among early adopters, where certain users go to the extent of characterizing it as a disruptive technology in many domains. Understanding such early adopters' sentiments is important because it can provide insights into the potential success or failure of the technology, as well as its strengths and weaknesses. In this paper, we conduct a mixed-method study using 10,732 tweets from early ChatGPT users. We first use topic modelling to identify the main topics and then perform an in-depth qualitative sentiment analysis of each topic. Our results show that the majority of the early adopters have expressed overwhelmingly positive sentiments related to topics such as Disruptions to software development, Entertainment and exercising creativity. Only a limited percentage of users expressed concerns about issues such as the potential for misuse of ChatGPT, especially regarding topics such as Impact on educational aspects. We discuss these findings by providing specific examples for each topic and then detail implications related to addressing these concerns for both researchers and users.

在本文中，创建了具有定制设计的执行器空间弦编码器的增强软机器人原型，以研究动态软机器人轨迹跟踪。软机器人原型嵌入了所提出的自适应被动性控制和有效的动态模型，使具有挑战性的轨迹跟踪任务成为可能。我们通过在不同的操作场景上执行实验验证：各种跟踪速度和外部干扰来探索跟踪准确性以及提出的控制策略的全部潜力。在所有实验场景中，提出的自适应被动控制都优于常规PD反馈线性化控制。实验分析详细介绍了所提出的方法的优势和缺点，并指出了未来软机器人动态控制的下一步。

脑出血（ICH）是最致命的中风子类型，死亡率高达52％。由于颅骨切开术引起的潜在皮质破坏，保守管理（注意等待）历史上一直是一种常见的治疗方法。最小的侵入性疏散最近已成为一种可公认的治疗方法，用于体积30-50 mL的深座性血肿的患者，但适当的可视化和工具敏感性仍然受到常规内窥镜方法的限制，尤其是较大的血肿体积（> 50 mL）。在本文中，我们描述了Aspihre的发展（脑部出血机器人疏散的手术平台），这是有史以来的第一个同心管机器人，该机器人使用现成的塑料管来进行MR引导ICH撤离，改善工具敏感性和程序可视化。机器人运动学模型是基于基于校准的方法和试管力学建模开发的，使模型可以考虑可变曲率和扭转偏转。使用可变增益PID算法控制旋转精度为0.317 +/- 0.3度。硬件和理论模型在一系列系统的基准和MRI实验中进行了验证，导致1.39 +\ -0.54 mm的管尖的位置精度。验证靶向准确性后，在MR引导的幻影凝块疏散实验中测试了机器人的疏散功效。该机器人能够在5分钟内撤离最初38.36 mL的凝块，使残留血肿为8.14 mL，远低于15 mL指南，表明良好的后疏散临床结果。
