In microarray data mining, one of the key problems is how to handle weak signals. Based on a bent piecewise linear accumulated distribution generally found in the microarray data, a new detectable...
All-angle zero reflection at metamaterial surfaces (2008)
Li, Xin, Liang, Zixian, Liu, Xiaohan, Jiang, Xunya, Zi, Jian
The authors study theoretically reflection on the surface of a metamaterial with a hyperbolic dispersion. It is found that reflection is strongly dependent on how the surface is terminated with...
Dirac Spectra and Edge States in Honeycomb Plasmonic Lattices (2008)
Han, Dezhuan, Lai, Yun, Zi, Jian, Zhang, Zhao-Qing, Chan, C. T.
We study theoretically the dispersion of plasmonic honeycomb lattices and find Dirac spectra for both dipole and quadrupole modes. Zigzag edge states derived from Dirac points are found in ribbons of...
Extrinsic photonic crystals (2005)
Xu, Chun, Han, Dezhuan, Wang, Xin, Liu, Xiaohan, Zi, Jian
Doped semiconductors are intrinsically homogeneous media. However, by applying an external magnetic field that has a spatially periodic variation, doped semiconductors can behave extrinsically like...
Enhanced transmission of optically thick metallic films at infrared wavelengths (2005)
Han, Dezhuan, Li, Xin, Wu, Fengqin, Zi, Jian
For an optically thick metallic film, the transmission for both s- and p-polarized waves is extremely low. If the metallic film is coated on both sides with a finite dielectric layer, light...
Protein flexibility prediction by an all-atom mean-field statistical theory (2005)
Pandey, B.P., Zhang, Chi, Yuan, Xianzhang, Zi, Jian, Zhou, Yaoqi
We extended a mean-field model to proteins with all atomic detail. The all-atom mean-field model was used to calculate the dynamic and thermodynamic properties of a three-helix bundle fragment of...
Universal behavior of localization of residue fluctuations in globular proteins (2003)
Wu, Yinhao, Yuan, Xianzhang, Gao, Xia, Fang, Haiping, Zi, Jian
Localization properties of residue fluctuations in globular proteins are studied theoretically by using the Gaussian network model. Participation ratio for each residue fluctuation mode is...
Two-dimensional photonic crystal polarizer (1999)
Zhang, Chun, Wan, Jun, Qiao, Feng, Zi, Jian
A novel polarizer made from two-dimensional photonic bandgap materials was demonstrated theoretically. This polarizer is fundamentally different from the conventinal ones. It can function in a wide...
Wang, Lingjun, Wei, Guanghong, Zi, Jian
A planar force-constant model is developed for longitudinal phonons of wurtzite GaN and AlN propagating along the [0001] direction. The proposed model is then applied to the study of the phonon modes...
Coloration strategies in peacock feathers
Zi, Jian, Yu, Xindi, Li, Yizhou, Hu, Xinhua, Xu, Chun, Wang, Xingjun, ...
We report the mechanism of color production in peacock feathers. We find that the cortex in differently colored barbules, which contains a 2D photonic-crystal structure, is responsible for...
