Loss of the autism associated gene Tbr1 disrupts prediction and encoding by prefrontal ensembles during socioemotional behaviors

Posted by dbos Hopkins

Kavli Affiliate: John Rubenstein and Vikaas Sohal | Authors: Marc Turner, Sarah Robinson-Schwartz, Siavash Fazel Darbandi, John L.R. Rubenstein and Vikaas Singh Sohal | Summary: Disruptions in many genes linked to autism spectrum disorder (ASD) affect synaptic function and socioemotional behaviors in mice. However, exactly how synaptic dysfunction alters neural activity patterns underlying behavior remains […]

Non-equilibrium ionization in the multiphase circumgalactic medium — impact on quasar absorption-line analyses

Posted by klaurent Chicago

Kavli Affiliate: Hsiaowen Chen |Summary:This paper presents an updated framework for studying the ionizing conditions and elemental abundances of photoionized, metal-enriched quasar absorption systems. The standard assumption of ionization equilibrium invoked in absorption line analyses requires gas to cool on longer timescales than ionic recombination (t_cool >> t_rec). However, this assumption may not be valid […]

BlackTHUNDER — A non-stellar Balmer break in a black hole-dominated little red dot at $z=7.04$

Posted by klaurent Cambridge

Kavli Affiliate: Debora Sijacki | Summary:Recent observations from JWST have revealed an abundant population of active galactic nuclei (AGN) and so-called “Little Red Dots” (LRDs) at $2lesssim z lesssim 11$, many of which are characterized by V-shaped UV-to-optical continua with turnovers around the Balmer limit. The physical nature of these LRDs is unclear, and it […]

On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Takada | Summary:We investigate the angular power spectrum ($C_ell)$ and angular correlation function ($w(θ)$) of galaxy number density field in the presence of the local-type primordial non-Gaussianity (PNG), explicitly accounting for the integral constraint in an all-sky survey. We show that the PNG signature in $C_ell$ is confined to low multipoles in […]

Global symmetries of quantum lattice models under non-invertible dualities

Posted by klaurent Tokyo

Kavli Affiliate: Masahito Yamazaki | Summary:Non-invertible dualities/symmetries have become an important tool in the study of quantum field theories and quantum lattice models in recent years. One of the most studied examples is non-invertible dualities obtained by gauging a discrete group. When the physical system has more global symmetries than the gauged symmetry, it has […]

Repulsive thermal van der Waals interaction in multi-species asymmetric electrolytes driven by external electric fields

Posted by dbos UCAS

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Guangle Du, David S. Dean, Bing Miao, Rudolf Podgornik, | Summary: It is well established that the long-range component of the thermal van der Waals interaction between two semi-infinite dielectrics becomes short-range when an electrolyte is present between them, this is the well known phenomenon of screening. […]

Whole-brain neural substrates of behavioral variability in the larval zebrafish

Posted by dbos Rockefeller

Kavli Affiliate: Alipasha Vaziri | Authors: Jason Manley and Alipasha Vaziri | Summary: Animals engaged in naturalistic behavior can exhibit a large degree of behavioral variability even under sensory invariant conditions. Such behavioral variability can include not only variations of the same behavior, but also variability across qualitatively different behaviors driven by divergent cognitive states, […]
