Generative inference unifies feedback processing for learning and perception in natural and artificial vision

Posted by dbos Columbia, This Week: Neuroscience

Kavli Affiliate: Kenneth Miller | Authors: Tahereh Toosi and Kenneth D Miller | Summary: We understand how neurons respond selectively to patterns in visual input to support object recognition; however, how these circuits support perceptual grouping, illusory percepts, and imagination is not understood. These perceptual experiences are thought to require combining what we have learned […]

An Axial-Vector Leptophilic Fifth Force Sourced by Solar Neutrinos

Posted by klaurent This Week: Astrophysics, Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Rundong Fang, Rundong Fang, , , | Summary: We investigate long-range, purely leptophilic axial-vector interactions mediated by a light gauge boson $A’$ that couples to charged leptons and, by weak symmetry, to left-handed neutrinos. We analyze two realizations, a minimal effective model with muon-only couplings and an […]

Quantifying robustness and locality of Majorana bound states in interacting systems

Posted by klaurent Delft, This Week: Nanoscience

Kavli Affiliate: Michael Wimmer | First 5 Authors: William Samuelson, William Samuelson, , , | Summary: Protecting qubits from perturbations is a central challenge in quantum computing. Topological superconductors with separated Majorana bound states (MBSs) provide a strong form of protection that only depends on the locality of perturbations. While the link between MBS separation, […]

Detection of ultra-high-energy cosmic rays in the southern hemisphere with FAST: data acquisition and preliminary results

Posted by klaurent Chicago, This Week: Astrophysics

Kavli Affiliate: Radomir Smida | First 5 Authors: Jakub Kmec, Jakub Kmec, , , | Summary: Ultra-high-energy cosmic rays (UHECRs) remain one of the greatest mysteries in astroparticle physics. The Fluorescence detector Array of Single-pixel Telescopes (FAST) is a next-generation cosmic ray experiment which utilizes ground-based fluorescence telescopes designed to detect these extremely rare particles […]

AnyPcc: Compressing Any Point Cloud with a Single Universal Model

Posted by klaurent Caltech, This Week: Nanoscience

Kavli Affiliate: Wei Gao | First 5 Authors: Kangli Wang, Kangli Wang, , , | Summary: Generalization remains a critical challenge for deep learning-based point cloud geometry compression. We argue this stems from two key limitations: the lack of robust context models and the inefficient handling of out-of-distribution (OOD) data. To address both, we introduce […]

ResearchGPT: Benchmarking and Training LLMs for End-to-End Computer Science Research Workflows

Posted by klaurent This Week: Theoretical Physics, UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Penghao Wang, Penghao Wang, , , | Summary: As large language models (LLMs) advance, the ultimate vision for their role in science is emerging: we could build an AI collaborator to effectively assist human beings throughout the entire scientific research process. We refer to this envisioned system […]

Exposing Blindspots: Cultural Bias Evaluation in Generative Image Models

Posted by klaurent This Week: Theoretical Physics, UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Huichan Seo, Huichan Seo, , , | Summary: Generative image models produce striking visuals yet often misrepresent culture. Prior work has examined cultural bias mainly in text-to-image (T2I) systems, leaving image-to-image (I2I) editors underexplored. We bridge this gap with a unified evaluation across six countries, an 8-category/36-subcategory […]

Detecting White Dwarf Binary Mergers with Gravitational Waves

Posted by klaurent Stanford, This Week: Astrophysics

Kavli Affiliate: Peter W. Graham | First 5 Authors: Giona Sala, Giona Sala, , , | Summary: Mergers of white dwarf binaries are a possible progenitor channel for Type Ia supernovae. While white dwarfs are abundant in the universe and relatively well understood, their gravitational wave signals have not yet been directly observed. In order […]

Canonical decision computations underlie behavioral and neural signatures of cooperation in primates

Posted by dbos This Week: Neuroscience, Yale

Kavli Affiliate: Anirvan Nandy | Authors: Weikang Shi, Olivia C. Meisner, Monika P. Jadi, Steve W. C. Chang and Anirvan S. Nandy | Summary: Successful cooperation requires dynamic integration of social cues. However, the neural mechanisms supporting this complex process remain unknown. Here, we reveal that the primate dorsomedial prefrontal cortex (dmPFC) implements a gaze-dependent […]

Exploiting Endogenous CRISPR-Cas9 System for Functional Engineering of Probiotic Lacticaseibacillus rhamnosus GG (LGG)

Posted by dbos Hopkins, This Week: Neuroscience

Kavli Affiliate: Michael Miller | Authors: Zifan Xie, Yong-Su Jin and Michael J Miller | Summary: Lacticaseibacillus rhamnosus GG (LGG) is one of the most extensively studied probiotic strains, widely used in food and health applications. However, the absence of efficient, precise genome editing methods has limited its broader potential and functional versatility. Here, we […]
