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 […]
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 […]
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 […]
Kavli Affiliate: Changhuei Yang | First 5 Authors: Haowen Zhou, Haowen Zhou, , , | Summary: Automation in optical microscopy is critical for enabling high-throughput imaging across a wide range of biomedical applications. Among the essential components of automated systems, robust autofocusing plays a pivotal role in maintaining image quality for both single-plane and volumetric […]

Meyers, William Dylan Hale, Akhilesh Pandey and Richard L. Huganir | Summary: Synaptic plasticity in the central nervous system enables the encoding, storing, and integrating new information. AMPA-type glutamate receptors (AMPARs) […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Benny Trakhtenbrot, Benny Trakhtenbrot, , , | Summary: We use the narrow [Ne v] $lambda$3427 emission line detected in the recently published JWST spectra of two galaxies, at z = 6.9 and 5.6, to study the key properties of the active galactic nuclei (AGN) and the supermassive […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: , , , , | Summary: We present a detailed analysis of the most luminous and obscured Active Galactic Nuclei (AGNs) detected in the ultra-hard X-ray band (14-195 keV) by Swift/BAT. Our sample comprises 21 X-ray luminous (log $L_X/rm erg,s^-1>44.6$, 2-10 keV) AGNs at $z<0.6$, optically classified […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Xiaojing Lin, Xiaojing Lin, , , | Summary: JWST observations have revealed a population of high-redshift "little red dots" (LRDs) that challenge conventional AGN models. We report the discovery of three local LRDs at $z = 0.1-0.2$, initially selected from the SDSS database, with follow-up optical/near-IR spectroscopy […]
Kavli Affiliate: Ke Wang | First 5 Authors: Xiao-Xiong Zeng, Xiao-Xiong Zeng, , , | Summary: In this paper, we investigate the power and efficiency of energy extraction through magnetic reconnection in the Kerr-Sen-AdS$_4$ black hole, with a primary focus on both the circular orbit and plunging region. We plot the allowed regions for energy […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Suyeong Jin, Suyeong Jin, , , | Summary: Graphene is a material with potential applications in electric, thermal, and mechanical fields, and has seen significant advancements in growth methods that facilitate large-scale production. However, defects during growth and transfer to other substrates can compromise the integrity and […]
