Fractal plasmonic metamaterials for subwavelength imaging (2009)
Huang, Xueqin, Ye, Dexin, Xiao, Shiyi, Huangfu, Jiangtao, Wang, Zhiyu, Ran, Lixin, ...
We show that a metallic plate with fractal-shaped slits can be homogenitized as a plasmonic metamaterial with plasmon frequency dictated by the fractal geometry. Owing to the all-dimensional...
Sub-diffraction-limit Observation Realized by Nonlinear Metamaterial Lens (2009)
Wang, Zhiyu, Luo, Yu, Peng, Liang, Huangfu, Jiangtao, Jiang, Tao, Wang, Dongxing, ...
In this paper, we show by experiment that by covering a thin flat nonlinear lens on the sources, the sub-diffraction-limit observation can be achieved by measuring either the near-field distribution...
Second-Harmonic Generation and Spectrum Modulation by Active Nonlinear Metamaterial (2009)
Wang, Zhiyu, Luo, Yu, Peng, Liang, Huangfu, Jiangtao, Jiang, Tao, Wang, Dongxing, ...
The nonlinear properties of a metamaterial sample composed of double-layer metallic patterns and voltage controllable diodes are experimentally investigated. Second harmonics and spectrum modulations...
Classification of Buildings in Nature Images (2006)
We present an un-supervised image recognition method based on a statistical learning theory (Support Vector Machine). Images are classified using randomly or regularly extracted sub-windows that are...
With recent improvements in methods for the acquisition, rendering and storing of 3D models, the need for retrieval of models from large 3D model database becomes more and more prominent in the...
An intact corneal epithelial cell barrier is essential for visual acuity, and is maintained by cell adhesion to the underlying basement membrane. The urokinase plasminogen activator (uPA) system...

The ectodomain of the paramyxovirus haemagglutinin-neuraminidase (HN) glycoprotein spike can be divided into two regions: a membrane-proximal, stalk-like structure and a terminal globular domain. The...
