Rarely categorical and highly separable: how neural representations change along the cortical hierarchy

Posted by dbos December 23, 2025January 12, 2026Columbia

Kavli Affiliate: Stefano Fusi and Liam Paninski | Authors: Lorenzo Posani, Shuqi Wang, Samuel Muscinelli, Liam Paninski and Stefano Fusi | Summary: A long-standing debate in neuroscience concerns whether individual neurons are organized into functionally distinct populations that encode information differently (“categorical” representations [1–3]) and the implications for neural computation. Here, we systematically analyzed how […]

Analytical quantification of strongly disordered discrete time crystals

Posted by klaurent December 23, 2025UCAS

Kavli Affiliate: Biao Huang | Summary:We introduce an analytical framework to calculate the values of key observables in a strongly disordered discrete time crystal (DTC) without fitting parameter. The perturbatively obtained closed-form formulae show quantitative agreement with numerical simulations of inverse participation ratios for eigenstate localization in Fock space, Edwards-Anderson parameters for spin-glass orders, mutual […]

BASS.L. Near-infrared Data Release 3: A Spectral Atlas and Characterization of AGN

Posted by klaurent December 23, 2025Peking

Kavli Affiliate: Claudio Ricci | Summary:We present an analysis of near-infrared (NIR) emission-line properties, AGN diagnostics, and circumnuclear gas dynamics for 453 hard X-ray selected (14$-$195 keV) AGN from the BAT AGN Spectroscopic Survey (BASS) NIR Data Release 3 (DR3; $langle z rangle=0.036$, $z<1.0$). This dataset is the largest compilation of rest-frame NIR spectroscopic observations […]

Squeezed States in Gravity

Posted by klaurent December 23, 2025MIT

Kavli Affiliate: Frank Wilczek | Summary:We present a general framework for the production of squeezed quantum states of the gravitational field in linearized quantum gravity. Time-dependent couplings in the quadratic part of the action generically produce squeezed states from the vacuum. Using the harmonic oscillator as an example, we describe three techniques to obtain the […]

Shear viscosity at finite magnetic field for graphene, non-relativistic and ultra-relativistic cases

Posted by klaurent December 23, 2025February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Present article has addressed finite magnetic field extension of previous work by Cho et al. (Phys. Rev. B 108, 235172, 2023) on microscopic calculation of shear viscosity for electron fluid in graphene system. Our calculation is based on the kinetic theory approach […]

On holography with ADE singularities

Posted by klaurent December 23, 2025Tokyo

Kavli Affiliate: Yuji Tachikawa | Summary:We study aspects of the AdS/CFT correspondence for $mathcalN=4$ $U(N)$ super Yang-Mills theory on $S^3/Γ$, where $Γsubset SU(2)$ is a finite subgroup, leading to an ADE singularity in the bulk AdS geometry. We show that a large vacuum degeneracy arises from the choice of gauge holonomy on $S^3/Γ$. On the […]

Highly Tunable Two-Qubit Interactions in Si/SiGe Quantum Dots by Interchanging the Roles of Qubit-Defining Gates

Posted by klaurent December 23, 2025Delft

Kavli Affiliate: Giordano Scappucci | Summary:Silicon quantum dot spin qubits have become a promising platform for scalable quantum computing because of their small size and compatibility with industrial semiconductor manufacturing processes. Although Si/SiGe heterostructures are commonly used to host spin qubits due to their high mobility and low percolation density, the SiGe spacer creates a […]

On the Effectiveness of Instruction-Tuning Local LLMs for Identifying Software Vulnerabilities

Posted by klaurent December 23, 2025February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Large Language Models (LLMs) show significant promise in automating software vulnerability analysis, a critical task given the impact of security failure of modern software systems. However, current approaches in using LLMs to automate vulnerability analysis mostly rely on using online API-based LLM […]

Lyman Continuum escaping from in-situ formed stars in a tidal bridge at z = 3

Posted by klaurent December 23, 2025February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We present an analysis of archival JWST NIRSpec IFS and HST imaging observations of the z = 3 Lyman-Continuum Emitter (LCE) candidate LACES104037. We show that a nearby galaxy, denoted LACES104037-S, has a redshift offset from the main galaxy by only $sim […]

Lyman Continuum escaping from in-situ formed stars in a tidal bridge at z = 3

Posted by klaurent December 23, 2025February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:In order to account for reionization of the early Universe, galaxies at that time must have had significantly higher escape fractions of Lyman Continuum (LyC) than observed in the present Universe. Any explanation invoked to explain LyC escape must agree with this […]
