Cell type-specific barcoding reveals the projectional architecture of the mouse midbrain dopaminergic system

Posted by dbos July 15, 2025July 23, 2025Hopkins, This Week: Neuroscience

Kavli Affiliate: Justus M Kebschull | Authors: Hyopil Kim, Cheng Xu, Craig Washington, Maggie Lowman and Justus M Kebschull | Summary: Brain-wide neural circuits are formed by the diverse axonal branching patterns of many individual neurons. Here we introduce POlNTseq (projections of interest by sequencing), a high-throughput and user-friendly barcoded connectomics method that uses cell […]

High-redshift AGN population in radiation-hydrodynamics simulations

Posted by klaurent July 15, 2025July 21, 2025MIT, This Week: Astrophysics

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Teodora-Elena Bulichi, Teodora-Elena Bulichi, , , | Summary: High-redshift active galactic nuclei (AGN) have long been recognized as key probes of early black hole growth and galaxy evolution. However, modeling this population remains difficult due to the wide range of luminosities and black hole masses involved, and […]

Odd-even parity dependent transport in an annular Kitaev chain

Posted by klaurent July 15, 2025July 21, 2025This Week: Theoretical Physics, UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Wei Wang, Wei Wang, , , | Summary: We investigate the impact of magnetic flux and the odd-even parity of lattice points $N$ on electron transport in an annular Kitaev chain, with an explanation provided from the energy band perspective. Three transport mechanisms including direct transmission (DT), […]

Efficient Branch-and-Bound for Submodular Function Maximization under Knapsack Constraint

Posted by klaurent July 15, 2025July 21, 2025This Week: Theoretical Physics, UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yimin Hao, Yimin Hao, , , | Summary: The submodular knapsack problem (SKP), which seeks to maximize a submodular set function by selecting a subset of elements within a given budget, is an important discrete optimization problem. The majority of existing approaches to solving the SKP are […]

Asymptotically Optimal Repair of Reed-Solomon Codes with Small Sub-Packetization under Rack-Aware Model

Posted by klaurent July 15, 2025July 21, 2025Peking, This Week: Astrophysics

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: This paper presents a comprehensive study on the asymptotically optimal repair of Reed-Solomon (RS) codes with small sub-packetization, specifically tailored for rack-aware distributed storage systems. Through the utilization of multi-base expansion, we introduce a novel approach that leverages monomials […]

EquiContact: A Hierarchical SE(3) Vision-to-Force Equivariant Policy for Spatially Generalizable Contact-rich Tasks

Posted by klaurent July 15, 2025July 21, 2025Berkeley, This Week: Nanoscience

Kavli Affiliate: Xiang Zhang | First 5 Authors: Joohwan Seo, Joohwan Seo, , , | Summary: This paper presents a framework for learning vision-based robotic policies for contact-rich manipulation tasks that generalize spatially across task configurations. We focus on achieving robust spatial generalization of the policy for the peg-in-hole (PiH) task trained from a small […]
