A magnetic reconnection origin for the soft X-ray excess in AGNMay 31 2013We present a new scenario to explain the soft X-ray excess in Active Galactic Nucleus. The magnetic reconnection could happen in a thin layer on the surface of accretion disk. Electrons are accelerated by shock wave and turbulence triggered by magnetic ... More

Strong decays of the newly observed $D(2550)$, $D(2600)$, $D(2750)$, and $D(2760)$Sep 02 2010Dec 21 2010The strong decay properties of the newly observed $D(2550)$, $D(2600)$, $D(2750)$ and $D(2760)$ are studied in a constituent quark model. It is predicted that the $D(2760)$ and $D(2750)$ seem to be two overlapping resonances. The $D(2760)$ could be identified ... More

Exact solution to the Schrödinger equation for the quantum rigid bodyNov 26 1999The exact solution to the Schr\"{o}dinger equation for the rigid body with the given angular momentum and parity is obtained. Since the quantum rigid body can be thought of as the simplest quantum three-body problem where the internal motion is frozen, ... More

Large Margin Low Rank Tensor AnalysisJun 11 2013Other than vector representations, the direct objects of human cognition are generally high-order tensors, such as 2D images and 3D textures. From this fact, two interesting questions naturally arise: How does the human brain represent these tensor perceptions ... More
