Algorithmic Strategies for Sustainable Reuse of Neural Network Accelerators with Permanent Faults

Kavli Affiliate: Ke Wang | First 5 Authors: Youssef A. Ait Alama, Sampada Sakpal, Ke Wang, Razvan Bunescu, Avinash Karanth | Summary: Hardware failures are a growing challenge for machine learning accelerators, many of which are based on systolic arrays. When a permanent hardware failure occurs in a systolic array, existing solutions include localizing and […]

Vortex-Induced Rings and Gaps within Protoplanetary Disks

Kavli Affiliate: Ruobing Dong | First 5 Authors: Xiaoyi Ma, Pinghui Huang, Cong Yu, Ruobing Dong, | Summary: Observations of protoplanetary disks have revealed the presence of both crescent-shaped and ring-like structures in dust continuum emission. These crescents are thought to arise from dust-trapping vortices generated by the Rossby Wave Instability (RWI), which induces density […]

X-ray properties of coronal emission in radio quiet Active Galactic Nuclei

Kavli Affiliate: Claudio Ricci | First 5 Authors: Sibasish Laha, Claudio Ricci, John C. Mather, Ehud Behar, Luigi C. Gallo | Summary: Active galactic nuclei (AGN) are powerful sources of panchromatic radiation. All AGN emit in X-rays, contributing around $sim 5-10%$ of the AGN bolometric luminosity. The X-ray emitting region, popularly known as the corona, […]

On the Relation between the Inclination Angle of the Accretion Disk and the Broad-line Region in Active Galactic Nuclei

Kavli Affiliate: Luis C. Ho | First 5 Authors: Rong Du, Luis C. Ho, Yuanze Ding, Ruancun Li, | Summary: Models of active galactic nuclei often invoke a close physical association between the broad-line region and the accretion disk. We evaluate this theoretical expectation by investigating the relationship between the inclination angle of the BLR […]

Dynamical evolution of massless particles in star clusters with NBODY6++GPU-MASSLESS: I. Free-floating MLPs

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Flammini Dotti, M. B. N. Kouwenhoven, Peter Berczik, Qi Shu, Rainer Spurzem | Summary: Context. Low-mass bodies, such as comets, asteroids, planetesimals, and free-floating planets, are continuously injected into the intra-cluster environment after expulsion from their host planetary systems. These can be modeled as massless particles […]

Discovery of Local Analogs to JWST’s Little Red Dots

Kavli Affiliate: Linhua Jiang | First 5 Authors: Ruqiu Lin, Zhen-Ya Zheng, Chunyan Jiang, Fang-Ting Yuan, Luis C. Ho | Summary: Recently, the James Webb Space Telescope (JWST) has revealed a new class of high redshift (high-$z$, $z>4$) compact galaxies which are red in the rest-frame optical and blue in the rest-frame UV as V-shaped […]

MoDULA: Mixture of Domain-Specific and Universal LoRA for Multi-Task Learning

Kavli Affiliate: Ran Wang | First 5 Authors: Yufei Ma, Zihan Liang, Huangyu Dai, Ben Chen, Dehong Gao | Summary: The growing demand for larger-scale models in the development of textbf{L}arge textbf{L}anguage textbf{M}odels (LLMs) poses challenges for efficient training within limited computational resources. Traditional fine-tuning methods often exhibit instability in multi-task learning and rely heavily […]

A comprehensive study of type I (thermonuclear) bursts in the new transient SRGA J144459.2$-$604207

Kavli Affiliate: Renxin Xu | First 5 Authors: Tao Fu, Zhaosheng Li, Yuanyue Pan, Long Ji, Yupeng Chen | Summary: We report analysis of $textit{Insight}$-HXMT observations of the newly discovered accreting millisecond pulsar SRGA J144459.2$-$604207. During the outburst, detected in 2024 February by $textit{eROSITA}$, the broadband persistent spectrum was well fitted by an absorbed Comptonization […]
