The SocialAI School: Insights from Developmental Psychology Towards Artificial Socio-Cultural Agents

Posted by klaurent MIT

Kavli Affiliate: Peter Ford | Summary:Developmental psychologists have long-established the importance of socio-cognitive abilities in human intelligence. These abilities enable us to enter, participate and benefit from human culture. AI research on social interactive agents mostly concerns the emergence of culture in a multi-agent setting (often without a strong grounding in developmental psychology). We argue […]

Large Language Models as Superpositions of Cultural Perspectives

Posted by klaurent MIT

Kavli Affiliate: Peter Ford | Summary:Large Language Models (LLMs) are often misleadingly recognized as having a personality or a set of values. We argue that an LLM can be seen as a superposition of perspectives with different values and personality traits. LLMs exhibit context-dependent values and personality traits that change based on the induced perspective […]

Search for Daily Modulation of MeV Dark Matter Signals with DAMIC-M

Posted by klaurent Chicago

Kavli Affiliate: Paolo Privitera | Summary:Dark Matter (DM) particles with sufficiently large cross sections may scatter as they travel through Earth’s bulk. The corresponding changes in the DM flux give rise to a characteristic daily modulation signal in detectors sensitive to DM-electron interactions. Here, we report results obtained from the first underground operation of the […]

High-energy Neutrinos from the Inner Circumnuclear Region of NGC 1068

Posted by klaurent Stanford

Kavli Affiliate: Rodriguez Enrique Lopez | Summary:High-energy neutrinos are detected by the IceCube Observatory in the direction of NGC 1068, the archetypical type II Seyfert galaxy. The neutrino flux, surprisingly, is more than an order of magnitude higher than the $γ$-ray upper limits at measured TeV energy, posing tight constraints on the physical conditions of […]

Hue selectivity from recurrent circuitry in Drosophila

Posted by klaurent Columbia

Kavli Affiliate: Rudy Behnia | Authors: Matthias P Christenson, Alvaro Sanz Diez, Sarah L Heath, Maia Saavedra-Weisenhaus, Atsuko Adashi, LF Abbott and Rudy Behnia | Summary: A universal principle of sensory perception is the progressive transformation of sensory information from broad non-specific signals to stimulus-selective signals that form the basis of perception. To perceive color, […]

The electrostatic fate of $N$-layer moiré graphene

Posted by klaurent Caltech

Kavli Affiliate: Stevan Nadj-Perge | Summary:Twisted $N$-layer graphene (TNG) moiré structures have recently been shown to exhibit robust superconductivity similar to twisted bilayer graphene (TBG). In particular for $N=4$ and $N=5$, the phase diagram features a superconducting pocket that extends beyond the nominal full filling of the flat band. These observations are seemingly at odds […]

Six-Point AdS Gluon Amplitudes from Flat Space and Factorization

Posted by dbos UCAS

Kavli Affiliate: Xinan Zhou | First 5 Authors: Luis F. Alday, Vasco Gonçalves, Maria Nocchi, Xinan Zhou, | Summary: We present a powerful new approach to compute tree-level higher-point holographic correlators. Our method only exploits the flat-space limit, where we point out a novel and important simplification, and factorization of amplitudes in AdS. In particular, […]
