The LAMOST Stellar Parameter Pipeline at Peking University --- LSP3
Maosheng Xiang, Xiaowei Liu, Haibo Yuan +17
We introduce the LAMOST Stellar Parameter Pipeline at Peking University --- LSP3, developed and implemented for the determinations of radial velocity and stellar atmosp…
Research of the active reflector antenna using laser angle metrology system
Yong Zhang, Jie Zhang, Dehua Yang +3
Active reflector is one of the key technologies for constructing large telescopes, especially for the millimeter/sub-millimeter radio telescopes. This article introduces a new effi…
Overview of the LAMOST survey in the first decade
Hongliang Yan, Haining Li, Song Wang +24
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), also known as the Guoshoujing Telescope, is a major national scientific facility for astronomical research l…
LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC): target selection and the first release of value-added catalogues
Haibo Yuan, Xiaowei Liu, Zhiying Huo +16
As a major component of the LAMOST Galactic surveys, the LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC) aims to survey a significant volume of the Galactic thin/…
Natural resources balance sheets accounting: theoretical framework and practice in the Shaanxi province of China
Wentao Wang, Guoping Li, Andreas Kontoleon +2
To achieve sustainable development, there is widespread of the need to protect natural resource and improve government oversight in achieving China's economic security and ecologic…
LAMOST Spectroscopic Survey of the Galactic Anticentre (LSS-GAC): the second release of value-added catalogues
Maosheng Xiang, Xiaowei Liu, Haibo Yuan +29
We present the second release of value-added catalogues of the LAMOST Spectroscopic Survey of the Galactic Anticentre (LSS-GAC DR2). The catalogues present values of radial velocit…
Relative Flux Calibration of the LAMOST Spectroscopic Survey of the Galactic Anti-center
Maosheng Xiang, Xiaowei Liu, Haibo Yuan +17
We have developed and implemented an iterative algorithm of flux calibration for the LAMOST Spectroscopic Survey of the Galactic anti-center (LSS-GAC). For a given LSS-GAC plate, t…
Testing the chaos bound in the spinor field of Einstein-Euler-Heisenberg-Anti-de Sitter spacetime
Xiaowei Li, Bingbing Chen, Guoping Li
Violations of the chaos bound have been observed in scalar fields. In this work, we investigate the Lyapunov exponents of chaotic particles in the spinor field of an Einstein-Euler…
Unambiguous identification of the indirect band nature of atomically thin hexagonal boron nitride
Lei Fu, Yuqing Hu, Ning Tang +10
Atomically thin hexagonal boron nitride (h-BN), especially monolayer, has garnered increasing attention due to its intriguing optical and light-matter-interaction properties. Howev…
Strong Gravitational Lensing in the Einstein-Proca Theory
Guoping Li, Yan Zhang, Li Zhang +2
Adopting the strong field limit approach, we investigate the strong gravitational lensing of a spherically symmetric spacetime in the Einstein-Proca theory. With the strong field l…
Chaos bound violation by spinning particles in Gauss-Bonnet-AdS black holes
Xiaowei Li, Mengxuan Wu, Guoping Li
The paper examines how spinning test particles in Gauss‑Bonnet anti‑de Sitter black holes can violate the chaos bound, showing that the Lyapunov exponent depends on particle spin,…
Newton Method for Soft Quadratic Surface Support Vector Machine with 0-1 Loss Function
Guoping Li, Wen Song
A nonlinear kernel-free soft quadratic surface support vector machine model with 0-1 loss function (-SQSSVM) is proposed for binary classification problems, which is non-c…
