Alternating north-south brightness ratio of Ganymede’s auroral ovals: Hubble Space Telescope observations around the Juno PJ34 flyby

Posted by klaurent MIT

Kavli Affiliate: George Clark | First 5 Authors: Joachim Saur, Stefan Duling, Alexandre Wennmacher, Clarissa Willmes, Lorenz Roth | Summary: We report results of Hubble Space Telescope observations from Ganymede’s orbitally trailing side which were taken around the flyby of the Juno spacecraft on June 7, 2021. We find that Ganymede’s northern and southern auroral […]

Arrestin-3 agonism at D3 dopamine receptors defines a subclass of second generation antipsychotics that promotes drug tolerance

Posted by klaurent UCSF

Kavli Affiliate: Kevin Bender | Authors: Selin Schamiloglu, Elinor Lewis, Anne C Hergarden, Kevin Bender and Jennifer L Whistler | Summary: ABSTRACT Second generation antipsychotics (SGAs) are front-line treatments for serious mental illness. Often, individual patients benefit only from some SGAs and not others. The mechanisms underlying this unpredictability in treatment efficacy remain unclear. All […]

The Photon Ring in M87*

Posted by klaurent Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Avery E. Broderick, Dominic W. Pesce, Paul Tiede, Hung-Yi Pu, Roman Gold | Summary: We report measurements of the gravitationally lensed secondary image — the first in an infinite series of so-called "photon rings" — around the supermassive black hole M87* via simultaneous modeling and imaging of […]

The Atacama Cosmology Telescope: limits on dark matter-baryon interactions from DR4 power spectra

Posted by dbos Cambridge

Kavli Affiliate: Blake Sherwin | First 5 Authors: Zack Li, Rui An, Vera Gluscevic, Kimberly K. Boddy, J. Richard Bond | Summary: Diverse astrophysical observations suggest the existence of cold dark matter that interacts only gravitationally with radiation and ordinary baryonic matter. Any nonzero coupling between dark matter and baryons would provide a significant step […]

Measurement of the $Ω_c^0$ lifetime at Belle II

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, L. Aggarwal, H. Ahmed | Summary: We report on a measurement of the $Omega_c^0$ lifetime using $Omega_c^0 to Omega^-pi^+$ decays reconstructed in $e^+e^-to cbar{c}$ data collected by the Belle II experiment and corresponding to $207~{rm fb^{-1}}$ of integrated luminosity. The […]

Internal states as a source of subject-dependent movement variability and their representation by large-scale networks

Posted by klaurent Hopkins

Kavli Affiliate: Kathleen Cullen & Sridevi Sarma | Authors: Macauley Smith Breault, Pierre Sacré, Zachary B Fitzgerald, John T Gale, Kathleen E Cullen, Jorge A González-Martínez and Sridevi V Sarma | Summary: Abstract A human’s ability to adapt and learn relies on reflecting on past performance. Such reflections form latent factors called internal states that […]

SYNTHESIS: A Semi-Asynchronous Path-Integrated Stochastic Gradient Method for Distributed Learning in Computing Clusters

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Zhuqing Liu, Xin Zhang, Jia Liu, , | Summary: To increase the training speed of distributed learning, recent years have witnessed a significant amount of interest in developing both synchronous and asynchronous distributed stochastic variance-reduced optimization methods. However, all existing synchronous and asynchronous distributed training algorithms suffer […]

Spin-Hall magnetoresistance in quasi-two-dimensional antiferromagnetic insulator/metal bilayer systems

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Takuto Ishikawa, Mamoru Matsuo, Takeo Kato, , | Summary: We study the temperature dependence of spin Hall magnetoresistance (SMR) in antiferromagnetic insulator (AFI)/metal bilayer systems. We calculate the amplitude of the SMR signal by using a quantum Monte Carlo simulation and examine how the SMR depends on […]
