Abstract:
Multi-dimensional scaling is used to solve characteristic polynomials of similarity matrixes, in order to determine a minimal-number SNP set (htSNPs (haplotype-tagging SNPS)) for identifying an arbitrary number of haplotypes in blocks with strong linkage disequilibrium. Thus, unnecessary SNP typing in blocks with strong linkage disequilibrium can be avoided.
Abstract:
A cathode ray tube has a vacuum envelope formed of a panel portion supporting a phosphor film on an inner surface thereof, a neck housing an electron gun, a funnel joining the panel and the neck, and a stem sealing an open end of the neck and mounting the electron gun via a plurality of pins extending through the stem. The inside diameters at the open end sealed by the stem and vicinities thereof become gradually larger toward the open end sealed by the stem, or retain at least a value substantially equal to an inside diameter of a major portion of the neck.
Abstract:
A structure of a photoconductive film related to a target of an image pickup tube of the photo conductivity type is disclosed. This photoconductive film is formed from mainly Se and Te is added in a central part thereof. Further, As, which is considered to form a deep trap level which captures electrons in Se and GaF.sub.3, etc. which form negative space charges by capturing electrons in Se are added in the region adjacent to the region where Te exists. In addition, a thickness of film in the region where GaF.sub.3, etc. exists is selected to be thinner (not smaller than 20 .ANG. and not larger than 90 .ANG.) than a value which has been adopted so far.
