Electroanatomic Mapping to determine Scar Regions in patients with Atrial Fibrillation
Jiyue He, Kuk Jin Jang, Katie Walsh +3
Left atrial voltage maps are routinely acquired during electroanatomic mapping in patients undergoing catheter ablation for atrial fibrillation. For patients, who have prior cathet…
You Don't Know When I Will Arrive: Unpredictable Controller Synthesis for Temporal Logic Tasks
Yu Chen, Shuo Yang, Rahul Mangharam +1
In this paper, we investigate the problem of synthesizing controllers for temporal logic specifications under security constraint. We assume that there exists a passive intruder (e…
Patient-Specific Heart Model Towards Atrial Fibrillation
Jiyue He, Arkady Pertsov, Sanjay Dixit +3
Atrial fibrillation is a heart rhythm disorder that affects tens of millions people worldwide. The most effective treatment is catheter ablation. This involves irreversible heating…
Fiber Organization has Little Effect on Electrical Activation Patterns during Focal Arrhythmias in the Left Atrium
Jiyue He, Arkady M. Pertsov, Elizabeth M. Cherry +5
Over the past two decades there has been a steady trend towards the development of realistic models of cardiac conduction with increasing levels of detail. However, making models m…
Local_INN: Implicit Map Representation and Localization with Invertible Neural Networks
Zirui Zang, Hongrui Zheng, Johannes Betz +1
Robot localization is an inverse problem of finding a robot's pose using a map and sensor measurements. In recent years, Invertible Neural Networks (INNs) have successfully solved…
Teaching Autonomous Systems Hands-On: Leveraging Modular Small-Scale Hardware in the Robotics Classroom
Johannes Betz, Hongrui Zheng, Zirui Zang +8
