Revisiting the "Fundamental Plane" of Black Hole Activity at Extremely Low Luminosities
Feng Yuan, Zhaolong Yu, Luis C. Ho
We investigate the origin of the X-ray emission in low-luminosity AGNs (LLAGNs). Yuan & Cui (2005) predicted that the X-ray emission should originate from jets rather than from an…
A pathway-based kernel boosting method for sample classification using genomic data
Li Zeng, Zhaolong Yu, Hongyu Zhao
The analysis of cancer genomic data has long suffered "the curse of dimensionality". Sample sizes for most cancer genomic studies are a few hundreds at most while there are tens of…
On the Origin of Ultraviolet Emission and the Accretion Model of Low-luminosity AGNs
Zhaolong Yu, Feng Yuan, Luis Ho
Low-luminosity active galactic nuclei (LLAGNs) are generally believed to be powered by an inner radiatively inefficient, advection-dominated accretion flow (ADAF), an outer truncat…
A general kernel boosting framework integrating pathways for predictive modeling based on genomic data
Li Zeng, Zhaolong Yu, Yiliang Zhang +1
Predictive modeling based on genomic data has gained popularity in biomedical research and clinical practice by allowing researchers and clinicians to identify biomarkers and tailo…
Correlation between the photon index and X-ray luminosity of black hole X-ray binaries and active galactic nuclei: observations and interpretation
Qi-Xiang Yang, Fu-Guo Xie, Feng Yuan +4
We investigate the observed correlation between the 2--10 keV X-ray luminosity (in unit of the Eddington luminosity; ) and the photon index () of the X-…
