Japanese pear (Pyrus pyrifolia Nakai) has a gametophytic self-incompatibility (GSI) mechanism controlled by a single S-locus with multiple S-haplotypes, each of which contains separate genes that determine the allelic identity of pistil and pollen. The pistil S gene is the S-ribonuclease (S-RNase) gene, whereas good candidates for the pollen S gene are the… (More)
This paper deals with the pseudo noise (PN) generating method for digital audio watermarking using time-spread echo hiding. In time-spread echo based audio watermarking, the secret payload is embedded in the form of multiple echoes spread by a pseudo noise sequence and the pseudo noise sequence is used as secret key. Generally, the pseudo noise sequence is… (More)
Realistic and interactively generated computer graphics are needed in various fields, such as for CGI-animated movie and in education. To express the realistic appearance of various materials, it is important to represent the specific optical properties for each material.
Metalated O-silyl cyanohydrins of beta-silyl-alpha,beta-epoxyaldehyde have been found to serve as functionalized homoenolate equivalents by a tandem sequence involving base-promoted ring opening of the epoxide, Brook rearrangement, and alkylation of the resulting allylic anion. On the basis of mechanistic studies involving competitive experiments using the… (More)
Reaction of gamma-silyl-beta,gamma-epoxybutanenitrile with a base generates an alpha-nitrile carbanion derivative of 4-siloxybut-3-enenitrile, which undergoes reaction with bis-electrophiles such as 1,omega-dihaloalkanes, omega-bromo-alpha,beta-unsaturated esters, and bisenoates to provide highly functionalized carbocycles.
The visual expression of a surface quality of human skin is required in a wide range of fields, such as in cosmetics industry. It is much harder, however, to generate intuitively and accurately a computer graphics (CG) image of human skin that has a desired impression without professional knowledge and skills because of its complex physical properties. It… (More)
