Evidence of Cosmic-Ray Acceleration up to Sub-PeV Energies in the Supernova Remnant IC 443.

Z. Cao, F Aharonian, Yuting Bai, Yiwang Bao et autres

Supernova remnants (SNRs) have been considered as the primary contributors to cosmic rays (CRs) in our Galaxy. However, the maximum energy of particles that can be accelerated by shocks of SNRs is uncertain, and SNRs' contribution to CRs around PeV energies is …

A BERT-Assisted LLM Framework for Knowledge Graph Construction

Yixin Jiang, Kaitian Huang, Ximing Zhang, Wang Xu et autres

In knowledge graph construction, traditional NLP models suffer from poor cross-domain adaptability, while large language models (LLMs) face issues of hallucinations and data shift in information extraction. To address these challenges, we propose a collaborative framework for LLM-based triple extraction that integrates …

Precise measurements of the cosmic ray proton energy spectrum in the “knee” region

Z. Cao, F. Aharonian, Y.X Bai, Y. W. Bao et autres

We report the high-purity identification of cosmic-ray (CR) protons and a precise measurement of their energy spectrum from 0.15 to 12 PeV using the Large High Altitude Air Shower Observatory (LHAASO). Abundant event statistics, combined with the simultaneous detection of electrons/photons, muons, …

Diagnosis of steam turbine rotor based on improved convolutional neural network algorithm

Miao Zhou, Hui Huang, Yanghai Li, Wang Xu

To address the challenges of insufficient precision and limited adaptability in conventional rotor fault diagnosis methods, we propose a new approach using convolutional neural networks. This aims to effectively identify complex and diverse fault patterns in a steam turbine rotor through a …

P-S Separation from Multi-Component Seismic Data Using Deep Convolutional Neural Networks

Yingchang Xiong, Tengfei Wang, Wang Xu, Jing Cheng

Summary The accurate separation of single-mode waves from multi-component seismic data is of great significance for elastic imaging and inversion. Traditional separation methods require accurate velocity information and do not perform well on the far offset. In this paper, we propose to …

Interaction Chamber Design for an Energy Continuously Tunable Sub-Mev Laser-Compton Gamma-Ray Source

Hang-Hua Xu, Hailong Wu, Jianhui Chen, Benji Xu et autres

Previously, fixed angle Laser-Compton Scattering (LCS) experiments have been conducted at the terminal of the 100 MeV LINAC of the Shanghai Institute of Applied Physics, using SINAP-I and SINAP-II facility. Sub-MeV energy continuously tunable laser-Compton light source device (SINAP-III) is an updated …

The nonlinear effect in relativistic Compton scattering for an intense circularly polarized laser

Wen Luo, H. B. Zhuo, Y. Y., Zhichao Zhu et autres

Compton scattering between an intense laser pulse and a relativistic electron beam offers a promising development path toward high-energy, high-brightness x- and gamma-ray sources. Increasing laser peak power to obtain intense x- and gamma rays causes nonlinear Compton scattering to occur. To …
