Growing Brains: Co-emergence of Anatomical and Functional Modularity in Recurrent Neural Networks

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Mikail Khona, Ila R. Fiete, Max Tegmark, | Summary: Recurrent neural networks (RNNs) trained on compositional tasks can exhibit functional modularity, in which neurons can be clustered by activity similarity and participation in shared computational subtasks. Unlike brains, these RNNs do not exhibit anatomical modularity, […]

Variability as a predictor for the hard-to-soft state transition in GX 339-4

Kavli Affiliate: Erin Kara | First 5 Authors: Matteo Lucchini, Marina Ten Have, Jingyi Wang, Jeroen Homan, Erin Kara | Summary: During the outbursts of black hole X-ray binaries (BHXRBs), their accretion flows transition through several states. The source luminosity rises in the hard state, dominated by non-thermal emission, before transitioning to the blackbody-dominated soft […]

An end-to-end calibration of the Mini-EUSO detector in space

Kavli Affiliate: Angela Olinto | First 5 Authors: Hiroko Miyamoto, Matteo Battisti, Dario Barghini, Alexander Belov, Mario Bertaina | Summary: Mini-EUSO is a wide Field-of-View (FoV, 44$^{circ}$) telescope currently in operation from a nadia-facing UV-transparent window in the Russian Zvezda module on the International Space Station (ISS). It is the first detector of the JEM-EUSO […]

Lyman Continuum Emission from Spectroscopically Confirmed Ly$α$ Emitters at $zsim3.1$

Kavli Affiliate: Linhua Jiang | First 5 Authors: , , , , | Summary: We present a study of Lyman continuum (LyC) emission in a sample of $sim$150 Ly$alpha$ emitters (LAEs) at $zapprox3.1$ in the Subaru-XMM Deep Survey field. These LAEs were previously selected using the narrowband technique and spectroscopically confirmed with Ly$alpha$ equivalent widths […]

The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES): driving science cases and expected outcomes

Kavli Affiliate: Bruce Macintosh | First 5 Authors: , , , , | Summary: The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES) is a $2-5~mu$m, high-contrast integral field spectrograph (IFS) currently being built for Keck Observatory. With both low ($Rlesssim250$) and medium ($Rsim3500-7000$) spectral resolution IFS modes, SCALES will detect and characterize […]

The classical field approximation of ultra light dark matter: quantum breaktimes, corrections, and decoherence

Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Alvaro Zamora, Michael Kopp, Tom Abel, | Summary: The classical field approximation is widely used to better understand the predictions of ultra-light dark matter. Here, we use the truncated Wigner approximation method to test the classical field approximation of ultra-light dark matter. This method approximates […]
