Small-Target Detection between SAR Images Based on Statistical Modeling of Log-Ratio Operator.

The log-ratio (LR) operator is well suited for change detection in synthetic aperture radar (SAR) amplitude or intensity images. In applying the LR operator to change detection in multi-temporal SAR images, a crucial problem is how to develop precise models for the LR statistics. In this study, we first derive analytically the probability density function (PDF) of the LR operator.

Complete mitochondrial genome sequence of the Asian golden cat, Catopuma temminckii.

In this study, the mitochondrial genome of Asian golden cat (Catopuma temminckii) is sequenced. The mitochondrial genome was 16,985 bp long, including 13 protein-coding genes, 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes, 1 control region and 1 origin of light-strand replication. The overall base composition of the mitochondrial genome was 32.

Online coregularization for multiview semisupervised learning.

We propose a novel online coregularization framework for multiview semisupervised learning based on the notion of duality in constrained optimization. Using the weak duality theorem, we reduce the online coregularization to the task of increasing the dual function. We demonstrate that the existing online coregularization algorithms in previous work can be viewed as an approximation of our dual ascending process using gradient ascent.
