Oligodendrocytes form paranodal bridges that generate chains of myelin sheaths that are vulnerable to degeneration with age

Kavli Affiliate: Dwight Bergles | Authors: Cody L. Call, Sarah A. Neely, Jason J. Early, Owen G. James, Lida Zoupi, Anna C. Williams, Siddharthan Chandran, David A. Lyons and Dwight E. Bergles | Summary: Myelin sheaths in the CNS are generated by the tips of oligodendrocyte processes, which wrap axons to accelerate action potential conduction, […]

Behavioral decomposition reveals rich encoding structure employed across neocortex

Kavli Affiliates: Jingyi Guo, Claudia Battistin, Tuce Tombaz, Bartul Mimica, Jonathan Whitlock | Authors: Bartul Mimica, Tuçe Tombaz, Claudia Battistin, Jingyi Guo Fuglstad, Benjamin A. Dunn and Jonathan R. Whitlock | Summary: The Cortical population code is pervaded by activity patterns evoked by movement, but how such signals relate to the natural actions of unrestrained […]

Decision formation in parietal cortex transcends a fixed frame of reference

Kavli Affiliate: Michael N Shadlen | Authors: NaYoung So and Michael N Shadlen | Summary: Neurons in the lateral intraparietal cortex (area LIP) represent the formation of a decision when it is linked to a specific action, such as an eye movement to a choice target. However, these neurons should be unable to represent a […]

The irreducible mass and the horizon area of LIGO’s black holes

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Davide Gerosa, Cecilia Maria Fabbri, Ulrich Sperhake, , | Summary: The mass of a Kerr black hole can be separated into irreducible and rotational components -the former is a lower limit to the energy that cannot be possibly extracted from the event horizon and is related to […]

TOI-2119: A transiting brown dwarf orbiting an active M-dwarf from NASA’s TESS mission

Kavli Affiliate: Edward H. Morgan | First 5 Authors: Theron W. Carmichael, Jonathan M. Irwin, Felipe Murgas, Enric Pallé, Keivan G. Stassun | Summary: We report the discovery of TOI-2119b, a transiting brown dwarf (BD) that orbits and is completely eclipsed by an active M-dwarf star. Using light curve data from the Transiting Exoplanet Survey […]

Listing Maximal k-Plexes in Large Real-World Graphs

Kavli Affiliate: Yi Zhou | First 5 Authors: Zhengren Wang, Yi Zhou, Mingyu Xiao, Bakhadyr Khoussainov, | Summary: Listing dense subgraphs in large graphs plays a key task in varieties of network analysis applications like community detection. Clique, as the densest model, has been widely investigated. However, in practice, communities rarely form as cliques for […]

Weak Ergodicity Breaking in Non-Hermitian Many-body Systems

Kavli Affiliate: Zheng Zhu | First 5 Authors: Qianqian Chen, Shuai A. Chen, Zheng Zhu, , | Summary: The recent discovery of persistent revivals in the Rydberg-atom quantum simulator has revealed a weakly ergodicity-breaking mechanism dubbed quantum many-body scars, which are a set of nonthermal states embedded in otherwise thermal spectra. Until now, such a […]

Mitigating Closed-model Adversarial Examples with Bayesian Neural Modeling for Enhanced End-to-End Speech Recognition

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Chao-Han Huck Yang, Zeeshan Ahmed, Yile Gu, Joseph Szurley, Roger Ren | Summary: In this work, we aim to enhance the system robustness of end-to-end automatic speech recognition (ASR) against adversarially-noisy speech examples. We focus on a rigorous and empirical "closed-model adversarial robustness" setting (e.g., on-device or […]
