Collective Bayesian Decision-Making in a Swarm of Miniaturized Robots for Surface Inspection

Posted by dbos Harvard

Kavli Affiliate: Radhika Nagpal | First 5 Authors: Thiemen Siemensma, Darren Chiu, Sneha Ramshanker, Radhika Nagpal, Bahar Haghighat | Summary: Robot swarms can effectively serve a variety of sensing and inspection applications. Certain inspection tasks require a binary classification decision. This work presents an experimental setup for a surface inspection task based on vibration sensing […]

FlowWalker: A Memory-efficient and High-performance GPU-based Dynamic Graph Random Walk Framework

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Junyi Mei, Shixuan Sun, Chao Li, Cheng Xu, Cheng Chen | Summary: Dynamic graph random walk (DGRW) emerges as a practical tool for capturing structural relations within a graph. Effectively executing DGRW on GPU presents certain challenges. First, existing sampling methods demand a pre-processing buffer, causing substantial […]

Searching for Hyper-compact star clusters in the Milky Way using LAMOST and Gaia

Posted by dbos Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Haibo Yuan, Yilun Wang, Zexi Niu, Huawei Zhang | Summary: During the early merger of the Milky Way, intermediate-mass black holes in merged dwarf galaxies may have been ejected from the center of their host galaxies due to gravitational waves, carrying some central stars along. […]

Dissecting Quantum Many-body Chaos in the Krylov Space

Posted by dbos UCAS

Kavli Affiliate: Huajia Wang | First 5 Authors: Liangyu Chen, Baoyuan Mu, Huajia Wang, Pengfei Zhang, | Summary: The growth of simple operators is essential for the emergence of chaotic dynamics and quantum thermalization. Recent studies have proposed different measures, including the out-of-time-order correlator and Krylov complexity. It is established that the out-of-time-order correlator serves […]

Microlensing near macro-caustics

Posted by dbos MIT

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Luke Weisenbach, Timo Anguita, Jordi Miralda-Escudé, Masamune Oguri, Prasenjit Saha | Summary: Microlensing near macro-caustics is a complex phenomenon in which swarms of micro-images produced by micro-caustics form on both sides of a macro-critical curve. Recent discoveries of highly magnified images of individual stars in massive […]
