Propagation Kernels

open access: yesCoRR, 2014
We introduce propagation kernels, a general graph-kernel framework for efficiently measuring the similarity of structured data. Propagation kernels are based on monitoring how information spreads through a set of given graphs. They leverage early-stage distributions from propagation schemes such as random walks to capture structural information encoded

Error Self-calibration Method in Spatial Spectrum Estimation

open access: yesLeida xuebao, 2014
An important bottleneck in spatial spectrum estimation theory is array errors. A new error self-calibration method is presented on the basis of active error calibration and online self-calibration theories.

Subcarrier-based Processing for Clutter Rejection in CP-OFDM Signal-based Passive Radar Using SFN Configuration (in English)

open access: yesLeida xuebao, 2013
Clutter rejection is a key technique used by passive radars for target detection. Especially when using Single Frequency Network (SFN) configuration, the multipath clutter and ground clutter increase several times more than during a single illuminator ...

On the propagation of dependences [PDF]

open access: yesPacific Journal of Mathematics, 1989
We quote the author's abstract: ``An alternative proof of recent uniqueness theorems by Shanyu Ji is given. Ji's results are extended to the propagation of certain dependences from analytic subsets to the total space. Also these results are lifted from \({\mathbb{C}}^ m\) to ramified covering spaces of \({\mathbb{C}}^ m\).

Innovation in Propagation of Fruit, Vegetable and Ornamental Plants

open access: yes, 2020
There are two primary forms of plant propagation: sexual and asexual. In nature, propagation of plants most often involves sexual reproduction, and this form is still used in several species.
