Kavli Affiliate: Wei Gao | First 5 Authors: Yiqing Xu, Wei Gao, David Hsu, , | Summary: Inverse reinforcement learning (IRL) seeks to infer a cost function that explains the underlying goals and preferences of expert demonstrations. This paper presents receding horizon inverse reinforcement learning (RHIRL), a new IRL algorithm for high-dimensional, noisy, continuous systems […]
Kavli Affiliate: V. S. Ramachandran | Authors: Vignesh Ramachandran, Gregory Hatlestad and Travis White | Summary: Background: One way single-celled eukaryotes respond to DNA damage stress is by modifying their gene expression, facilitating genomic repair. Gene expression responses to DNA damage induced by methyl methanesulfonate (MMS) have been studied in the model organism Saccharomyces cerevisiae. […]
Kavli Affiliate: Solomon Snyder | Authors: Robin Roychaudhuri, Hasti Atashi and Solomon Snyder | Summary: The hippocampal CA3 subregion is a densely connected recurrent circuit that supports memory consolidation and retrieval by generating and storing sequential neuronal activity patterns that reflect recent experience. The encoding of precise temporal firing patterns in CA3 ensembles during awake-behavior […]
Kavli Affiliate: Solomon Snyder | Authors: Robin Roychaudhuri, Hasti Atashi and Solomon Snyder | Summary: The adult subventricular zone is one of the two neurogenic niches that continuously produce newborn neurons. Here we show that serine racemase (SR), an enzyme that catalyzes the racemization of L-serine to D-serine and vice versa, affects neurogenesis in the […]
Kavli Affiliate: John Reynolds | Authors: Courtney Glavis-Bloom, Casey R Vanderlip and John H Reynolds | Summary: Aging is the greatest risk factor for the development of neurodegenerative diseases, yet we still do not understand how the aging process leads to pathological vulnerability. The research community has relied heavily on mouse models, but the considerable […]
Kavli Affiliate: Robert Hawkins | Authors: Sreejan Kumar, Theodore R. Sumers, Takateru Yamakoshi, Ariel Goldstein, Uri Hasson, Kenneth A. Norman, Thomas L. Griffiths, Robert D. Hawkins and Samuel A. Nastase | Summary: Piecing together the meaning of a narrative requires understanding not only the individual words but also the intricate relationships between them. How does […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Jared A. Goldberg, Yan-fei Jiang, Lars Bildsten, , | Summary: Using Athena++, we perform 3D Radiation-Hydrodynamic calculations of the radiative breakout of the shock wave in the outer envelope of a red supergiant (RSG) which has suffered core collapse and will become a Type IIP supernova. The […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Jason T. Hinkle, Christopher S. Kochanek, Benjamin J. Shappee, Patrick J. Vallely, Katie Auchettl | Summary: We analyze high-cadence data from the Transiting Exoplanet Survey Satellite (TESS) of the ambiguous nuclear transient (ANT) ASASSN-18el. The optical changing-look phenomenon in ASASSN-18el has been argued to be due to […]

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Dan Hooper, Aurora Ireland, Gordan Krnjaic, , | Summary: The origin of our universe’s cosmological magnetic fields remains a mystery. In this study, we consider whether these magnetic fields could have been generated in the early universe by a population of charged, spinning primordial black holes. To […]
