Run Time Assured Reinforcement Learning for Six Degree-of-Freedom Spacecraft Inspection
Kyle Dunlap, Kochise Bennett, David van Wijk +2
The trial and error approach of reinforcement learning (RL) results in high performance across many complex tasks, but it can also lead to unsafe behavior. Run time assurance (RTA)…
Accurate Prediction of Chemical Shifts for Aqueous Protein Structure for "Real World" Cases using Machine Learning
Jie Li, Kochise C. Bennett, Yuchen Liu +2
Accurate prediction of NMR chemical shifts can in principle help refine aqueous solution structure of proteins to the quality of X-ray structures. We report a new machine learning…
A Multi-Resolution 3D-DenseNet for Chemical Shift Prediction in NMR Crystallography
Shuai Liu, Jie Li, Kochise C. Bennett +6
We have developed a deep learning algorithm for chemical shift prediction for atoms in molecular crystals that utilizes an atom-centered Gaussian density model for the 3D data repr…
Strong Anisotropy in Liquid Water upon Librational Excitation using Terahertz Laser Fields
Fabio Novelli, Luis Ruiz Pestana, Kochise C. Bennett +9
Tracking the excitation of water molecules in the homogeneous liquid is challenging due to the ultrafast dissipation of rotational excitation energy through the hydrogen-bonded net…
X-Ray sum frequency generation; direct imaging of ultrafast electron dynamics
Jérémy R. Rouxel, Markus Kowalewski, Kochise Bennett +1
X-ray diffraction from molecules in the ground state produces an image of their charge density, and time-resolved X-ray diffraction can thus monitor the motion of the nuclei. Howev…
Linear and Nonlinear Time- and Frequency-Domain Spectroscopy with Multiple Frequency Combs
Kochise Bennett, Jeremy Rouxel, Shaul Mukamel
Two techniques that employ equally spaced trains of optical pulses to map an optical high frequency into a low frequency modulation of the signal that can be detected in real time…
