    Abstract: As a calcium indicator protein having an excellent fluorescent characteristic and calcium reactivity, there is provided DNA in which one of a nucleotide sequence derivative of a calmodulin-binding sequence (ckkap sequence) of calcium/calmodulin-dependent protein kinase kinase and a nucleotide sequence encoding a calcium-binding sequence (CaM sequence) of calmodulin is linked to a 5? end of a nucleotide sequence encoding a fluorescent protein, and the other nucleotide sequence is linked to a 3? end of the nucleotide sequence encoding the fluorescent protein. The calcium indicator protein encoded by this DNA, which based on the derivative of the ckkap sequence as a binding domain for the calcium-bound CaM sequence, exhibits a fluorescent characteristic and calcium reactivity superior to those of conventional calcium indicator proteins.

  • Publication number: 20130258259
    Abstract: Color reproduction is improved by reducing color noise without changing color signal processing of a device in such a manner to match a new color filter arrangement. The film thickness of a green (G) color layer in a Bayer color arrangement is made thin to be the green (G) color layer having a steeply inclined spectral characteristic with a high range of transmissivity extended towards the short wavelength, and a yellow (Y1) color layer with a thin film thickness is newly stacked on the thinned green (G1) color layer. Thereby the y-axis value of the spectral characteristic of green (G) of the green (G) color layer becomes greater than or equal to 0.45 and less than or equal to 0.60 on a CIE chromaticity diagram.

A mark may be formed so that a reproduction signal level in the recorded mark of auxiliary data write once recorded on the reflective film is increased, and a reproduction signal level is decreased in an optical recording medium prepared by physically transferring the surface shape of the pits and lands of the substrate. A pirated optical recording medium may be determined in this manner.
