Application Fields

In this paper, some virtuallab experiments have been done, in which the we get extraordinary transmission phenomenon by adding dielectric coating in the subwavelength periodic metallic slits. It is proved that dielectric coatings on the metal films can excite a surface wave which is transmitted in the metal slits by dielectric waveguides, and the symmetric wrapped dielectric cladding around the metal gains almost 10 times as great transmission as two surfaces cladding does. The paper explores a preliminary physics mechanism of this extraordinary transmission, which gets some valuable results in the application fields.

Chromatin assembly involves the combined action of ATP-dependent motor proteins and histone chaperones. Because motor proteins in chromatin assembly also function as chromatin remodeling factors, we investigated the relationship between ATP-driven chromatin assembly and chromatin remodeling in the generation of periodic nucleosome arrays. We found that chromatin remodeling-defective Chd1 motor proteins are able to catalyze ATP-dependent chromatin assembly. The resulting nucleosomes are not, however, spaced in periodic arrays. Wild-type Chd1, but not chromatin remodeling-defective Chd1, can catalyze the conversion of randomly-distributed nucleosomes into periodic arrays. These results reveal a functional distinction between ATP-dependent nucleosome assembly and chromatin remodeling, and suggest a model for chromatin assembly in which randomly-distributed nucleosomes are formed by the nucleosome assembly function of Chd1, and then regularly-spaced nucleosome arrays are generated by the chromatin remodeling activity of Chd1. These findings uncover an unforeseen level of specificity in the role of motor proteins in chromatin assembly.
