Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Roxana Rosca-Mead, Ulrich Sperhake, Christopher J. Moore, Michalis Agathos, Davide Gerosa | Summary: This paper provides an extended exploration of the inverse-chirp gravitational-wave signals from stellar collapse in massive scalar-tensor gravity reported in [Phys. Rev. Lett. {bf 119}, 201103]. We systematically explore the parameter space that characterizes […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Silviu-Marian Udrescu, Max Tegmark, , , | Summary: We present a method for unsupervised learning of equations of motion for objects in raw and optionally distorted unlabeled video. We first train an autoencoder that maps each video frame into a low-dimensional latent space where the laws of […]
Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Nolan Denman, Andre Renard, Keith Vanderlinde, Philippe Berger, Kiyoshi Masui | Summary: We present an overview of the Graphics Processing Unit (GPU) based spatial processing system created for the Canadian Hydrogen Intensity Mapping Experiment (CHIME). The design employs AMD S9300x2 GPUs and readily-available commercial hardware in its […]
