Kavli Affiliate: Jia Liu | First 5 Authors: Yuyang Zhang, Xinhe Zhang, Jia Liu, Na Li, | Summary: In this paper, we focus on learning linear dynamical systems under noisy observations. In this setting, existing algorithms either yield biased parameter estimates, or suffer from large sample complexities. To address these issues, we adapt the instrumental […]
Kavli Affiliate: Joshua Frieman | First 5 Authors: Ryn Grutkoski, Hayley J. Macpherson, John T. Giblin Jr, Joshua Frieman, | Summary: We use numerical relativity to study the violent preheating era at the end of inflation. This epoch can result in highly nonlinear fluctuations in density and gravitational potential which feed back onto the averaged […]
Kavli Affiliate: Jeremy Nathans | Authors: Yanshu Wang, Amir Rattner, Zhongming Li, Philip M Smallwood and Jeremy Nathans | Summary: Cajal-Retzius (CR) cells are glutamatergic neurons that transiently populate the most superficial layer of the isocortex and allocortex during development, serving an essential role during both prenatal and early postnatal brain development. Notably, these cells […]

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Bozo Vareskic, Finn G. Kennedy, Takashi Taniguchi, Kenji Watanabe, Kenji Yasuda | Summary: We fabricate and measure electrically-gated tunnel junctions in which the insulating barrier is a sliding van der Waals ferroelectric made from parallel-stacked bilayer hexagonal boron nitride and the electrodes are single-layer graphene. Despite […]
Kavli Affiliate: Xian Chen | First 5 Authors: Julian Bäumler, Louis Blöcher, Lars-Joel Frey, Xian Chen, Markus Bayer | Summary: The dissemination of online hate speech can have serious negative consequences for individuals, online communities, and entire societies. This and the large volume of hateful online content prompted both practitioners’, i.e., in content moderation or […]
Kavli Affiliate: Elise Jennings | First 5 Authors: Ronny Müller, Maximilian Zanner, Mika Schielein, Martin Rüfenacht, Elise Jennings | Summary: We develop a parametric error model to construct a digital twin of a superconducting transmon qubit device. The model parameters are extracted from hardware calibration data and supplementary benchmarking circuits, providing a dynamic, system-specific representation […]
Kavli Affiliate: Giulia Quattrocolo | Authors: Kristian Moan, Robert P Machold and Giulia Quattrocolo | Summary: Cajal-Retzius (CR) cells are glutamatergic neurons that transiently populate the most superficial layer of the isocortex and allocortex during development, serving an essential role during both prenatal and early postnatal brain development. Notably, these cells disappear from most cortical […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Jia-Lai Kang, Chris Done, Scott Hagen, Mai Liao, Matthew J. Temple | Summary: Accretion flows in both stellar and supermassive black holes show a distinct spectral transition. This is seen directly in binaries and changing look AGN, and also in a recent sample of eROSITA X-ray […]
