Research progress of cerebral small vessel disease associated with immunoinflammatory mechanisms

Publikováno v: Chinese Journal of Contemporary Neurology and Neurosurgery, Vol 21, Iss 05, Pp 345-349 (2021)

Cerebral small vessel disease (CSVD) is a type of intracranial vascular disease characterized by recurrent stroke and neurodegenerative progression. The pathogenesis of CSVD is still unclear, and immunoinflammatory mechanisms such as blood⁃brain ba

LAMOST medium-resolution spectroscopic survey of binarity and exotic star (LAMOST-MRS-B): Observation strategy and target selection

Autor: Li, Jiao, Li, Jiang-Dan, Guo, Yan-Jun, Han, Zhan-Wen, Chen, Xue-Fei, Liu, Chao, Ge, Hong-Wei, Jiang, Deng-Kai, Li, Li-Fang, Zhang, Bo, Liu, Jia-Ming, Tian, Hao, Zhang, Hao-Tong, Yuan, Hai-Long, Cui, Wen-Yuan, Ren, Juan-Juan, Cai, Jing-Hao, Shi, Jian-Rong

LAMOST-MRS-B is one of the sub-surveys of LAMOST medium-resolution (R~7500) spectroscopic survey. It aims at studying the statistical properties (e.g., binary fraction, orbital period distribution, mass ratio distribution) of binary stars and exotic

Report

The Spectroscopic Binaries from LAMOST Medium-Resolution Survey (MRS). I. Searching for Double-lined Spectroscopic Binaries (SB2s) with Convolutional Neural Network

Autor: Zhang, Bo, Jing, Ying-Jie, Yang, Fan, Wan, Jun-Chen, Ji, Xin, Fu, Jian-Ning, Liu, Chao, Zhang, Xiao-Bin, Luo, Feng, Tian, Hao, Zhou, Yu-Tao, Wang, Jia-Xin, Guo, Yan-Jun, Zong, Weikai, Xiong, Jian-Ping, Li, Jiao

We developed a convolutional neural network (CNN) model to distinguish the double-lined spectroscopic binaries (SB2s) from others based on single exposure medium-resolution spectra ($R\sim 7,500$). The training set consists of a large set of mock spe

Binary fraction of O and B-type stars from LAMOST data

Autor: Luo, Feng, Zhao, Yong-Heng, Li, Jiao, Guo, Yan-Jun, Liu, Chao

Binary stars plays important role in the evolution of stellar populations . The intrinsic binary fraction ($f_{bin}$) of O and B-type (OB) stars in LAMOST DR5 was investigated in this work. We employed a cross-correlation approach to estimate relativ
