$texttt{StreamSculptor}$: Hamiltonian Perturbation Theory for Stellar Streams in Flexible Potentials with Differentiable Simulations

Posted by dbos Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Jacob Nibauer, Ana Bonaca, David N. Spergel, Adrian M. Price-Whelan, Jenny E. Greene | Summary: Stellar streams retain a memory of their gravitational interactions with small-scale perturbations. While perturbative models for streams have been formulated in action-angle coordinates, a direct transformation to these coordinates is only […]

Data-Efficient Low-Complexity Acoustic Scene Classification via Distilling and Progressive Pruning

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Bing Han, Wen Huang, Zhengyang Chen, Anbai Jiang, Pingyi Fan | Summary: The goal of the acoustic scene classification (ASC) task is to classify recordings into one of the predefined acoustic scene classes. However, in real-world scenarios, ASC systems often encounter challenges such as recording device mismatch, […]

Superposition- and interference-induced optical spectrum distortion in the figure-9 fiber laser

Posted by dbos Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Guochao Wang, Kangrui Chang, Haobin Zheng, Yongzhuang Zhou | Summary: The spectrum of the output pulses from the figure-9 laser typically exhibits more distortion than the spectra from mode-locked lasers based on other saturable absorbers and the spectrum of its intracavity pulses. Here, we demonstrate […]

Evidence for a shock-compressed magnetic field in the northwestern rim of Vela Jr. from X-ray polarimetry

Posted by dbos Stanford

Kavli Affiliate: Nicola Omodei | First 5 Authors: Dmitry A. Prokhorov, Yi-Jung Yang, Riccardo Ferrazzoli, Jacco Vink, Patrick Slane | Summary: Synchrotron X-ray emission has been detected from nearly a dozen young supernova remnants (SNRs). X-rays of synchrotron origin exhibit linear polarization in a regular, non-randomly oriented magnetic field. The significant polarized X-ray emission from […]

A simple accurate way to model noise-seeded ultrafast nonlinear processes

Posted by dbos Cornell

Kavli Affiliate: Frank Wise | First 5 Authors: Yi-Hao Chen, Frank Wise, , , | Summary: Noise can play an important role in nonlinear pulse propagation. It is not only the origin of fluctuations in supercontinuum but can also determine the generated signal amplitude and phase, as seen in phenomena such as noise-seeded four-wave mixing […]

EACO-RAG: Towards Distributed Tiered LLM Deployment using Edge-Assisted and Collaborative RAG with Adaptive Knowledge Update

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Jiaxing Li, Chi Xu, Lianchen Jia, Feng Wang, Cong Zhang | Summary: Large language models (LLMs) have demonstrated impressive capabilities in language tasks, but they require high computing power and rely on static knowledge. To overcome these limitations, Retrieval-Augmented Generation (RAG) incorporates up-to-date external information into LLMs […]

Drosophila Trus, the orthologue of mammalian PDCD2L, is required for proper cell proliferation, larval developmental timing, and oogenesis

Posted by dbos Columbia

Kavli Affiliate: Michael Goldberg | Authors: Saeko Takada, Bonnie J. Bolkan, MaryJane O’Connor, Michael Goldberg and Michael B. O’Connor | Summary: Toys are us (Trus) is the Drosophila ortholog of mammalian Programmed Cell Death 2-Like (PDCD2L), a protein that has been implicated in ribosome biogenesis, cell cycle regulation, and oncogenesis. In this study, we examined […]
