Intercalated amygdala dysfunction drives extinction deficits in the Sapap3 mouse model of obsessive-compulsive disorder

Posted by klaurent UCSF

Kavli Affiliate: Anatol Kreitzer | Authors: Robyn St. Laurent, Kelly M Kusche, Anatol C Kreitzer and Robert C Malenka | Summary: Background The avoidance of aversive stimuli due to negative reinforcement learning is critical for survival in real-world environments, which demand dynamic responding to both positive and negative stimuli that often conflict with each other. […]

Approximate Analytical Solutions for the Circular Restricted Three-Body Problem Including Non-Hamiltonian Solar Radiation Pressure

Posted by Chicago

Kavli Affiliate: David W. Miller | First 5 Authors: Hailee Hettrick, David W. Miller, Begum Cannataro, , | Summary: The circular restricted three-body problem (CR3BP) with solar radiation pressure (SRP) has often been analyzed with assumptions made on a spacecraft’s attitude, such that the problem remains Hamiltonian. These assumptions are unsatisfactorily limiting for a starshade […]

Flux-tunable Kitaev chain in a quantum dot array

Posted by dbos Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Juan Daniel Torres Luna, A. Mert Bozkurt, Michael Wimmer, Chun-Xiao Liu, | Summary: Connecting quantum dots through Andreev bound states in a semiconductor-superconductor hybrid provides a platform to create a Kitaev chain. Interestingly, in a double quantum dot, a pair of poor man’s Majorana zero modes can […]

The PFS view of TOI-677 b: A spin-orbit aligned warm Jupiter in a dynamically hot system

Posted by klaurent MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Qingru Hu, Malena Rice, Xian-Yu Wang, Songhu Wang, Avi Shporer | Summary: TOI-677 b is part of an emerging class of “tidally-detached” gas giants ($a/R_star gtrsim 11$) that exhibit large orbital eccentricities and yet low stellar obliquities. Such sources pose a challenge for models of giant planet […]

The TESS-Keck Survey. XVIII. A sub-Neptune and spurious long-period signal in the TOI-1751 system

Posted by klaurent MIT

Kavli Affiliate: Alan M. Levine | First 5 Authors: Anmol Desai, Emma V. Turtelboom, Caleb K. Harada, Courtney D. Dressing, David R. Rice | Summary: We present and confirm TOI-1751 b, a transiting sub-Neptune orbiting a slightly evolved, solar-type, metal-poor star ($T_{eff} = 5996 pm 110$ K, $log(g) = 4.2 pm 0.1$, V = 9.3 […]

A Strontium-rich Ultra Metal-poor Star in the Atari Disk Component

Posted by klaurent MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Mohammad K. Mardini, Anna Frebel, Anirudh Chiti, , | Summary: We report on the discovery of the first ultra metal-poor (UMP) star 2MASS~J20500194$-$6613298 (J2050$-$6613; mbox{[Fe/H] = $-4.05$}) selected from the Gaia BP/RP spectral catalog that belongs to the ancient Atari disk component. We obtained a high-resolution spectrum […]

Neurofeedback training can modulate task-relevant memory replay in rats

Posted by klaurent UCSF

Kavli Affiliate: Loren Frank | Authors: Anna K Gillespie, Daniela A Astudillo Maya, Eric L. Denovellis, Sachi Desse and Loren M Frank | Summary: Hippocampal replay – the time-compressed, sequential reactivation of ensembles of neurons related to past experience – is a key neural mechanism of memory consolidation. Replay typically coincides with a characteristic pattern […]
