Why Are Halo Coronal Mass Ejections Faster? [PDF]
, 2010 Halo coronal mass ejections (CMEs) were found to be significantly faster than normal CMEs, which was a long-standing puzzle. In order to solve the puzzle, we first investigate the observed properties of 31 limb CMEs that display clearly loop-shaped frontal loops.

Joint Action is a Framework for Understanding Partnerships Between Humans and Upper Limb Prostheses [PDF]
arXiv, 2022 Recent advances in upper limb prostheses have led to significant improvements in the number of movements provided by the robotic limb. However, the method for controlling multiple degrees of freedom via user-generated signals remains challenging. To address this issue, various machine learning controllers have been developed to better predict movement ...

Hierarchical generative modelling for autonomous robots [PDF]
arXiv, 2023 Humans can produce complex whole-body motions when interacting with their surroundings, by planning, executing and combining individual limb movements. We investigated this fundamental aspect of motor control in the setting of autonomous robotic operations. We approach this problem by hierarchical generative modelling equipped with multi-level planning-

Using Learned Predictions as Feedback to Improve Control and Communication with an Artificial Limb: Preliminary Findings [PDF]
arXiv, 2014 Many people suffer from the loss of a limb. Learning to get by without an arm or hand can be very challenging, and existing prostheses do not yet fulfil the needs of individuals with amputations. One promising solution is to provide greater communication between a prosthesis and its user. Towards this end, we present a simple machine learning interface
