Differential Control of Inhibitory and Excitatory Nerve Terminal Function by Mitochondria

Posted by dbos Rockefeller

Kavli Affiliate: Timothy A. Ryan | Authors: Kirsten Bredvik and Timothy A Ryan | Summary: Inhibitory neurons shape the brain’s computational landscape and rely on different cellular architectures and intrinsic properties than excitatory neurons. Maintenance of the overall balance of excitatory (E) versus inhibitory (I) drive is essential, as disruptions can lead to neuropathological conditions, […]

Adjacent Leader Decentralized Stochastic Gradient Descent

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Haoze He, Jing Wang, Anna Choromanska, , | Summary: This work focuses on the decentralized deep learning optimization framework. We propose Adjacent Leader Decentralized Gradient Descent (AL-DSGD), for improving final model performance, accelerating convergence, and reducing the communication overhead of decentralized deep learning optimizers. AL-DSGD relies on […]

Symmetrically Threaded SQUIDs As Next Generation Kerr-cat Qubits

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Bibek Bhandari, Irwin Huang, Ahmed Hajr, Kagan Yanik, Bingcheng Qing | Summary: Kerr-cat qubits are bosonic qubits with autonomous protection against bit-flips. They have been studied widely using driven Superconducting Nonlinear Asymmetric Inductive eLement (SNAIL) oscillators. We theoretically investigate an alternate circuit for the Kerr-cat qubit, namely […]

Sub-relativistic Outflow and Hours-Timescale Large-amplitude X-ray Dips during Super-Eddington Accretion onto a Low-mass Massive Black Hole in the Tidal Disruption Event AT2022lri

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Yuhan Yao, Muryel Guolo, Francesco Tombesi, Ruancun Li, Suvi Gezari | Summary: We present the tidal disruption event (TDE) AT2022lri, hosted in a nearby ($approx!144$ Mpc) quiescent galaxy with a low-mass massive black hole ($10^4,M_odot < M_{rm BH} < 10^6,M_odot$). AT2022lri belongs to the TDE-H+He subtype. More […]

The Empirical and Radiative Transfer Hybrid (EaRTH) Disk Model: Merging Analyses of Protoplanetary Dust Disk Mineralogy and Structure

Posted by dbos MIT

Kavli Affiliate: David A. Principe | First 5 Authors: William Grimble, Joel Kastner, Christophe Pinte, Beth Sargent, David A. Principe | Summary: Our understanding of how exoplanets form and evolve relies on analyses of both the mineralogy of protoplanetary disks and their detailed structures; however, these key complementary aspects of disks are usually studied separately. […]
