The genome size of Cyclops in cells at early stages of cleavage (up to the fifth division) and in somatic cells was estimated by static digital Feulgen cytophotometry in order to study quantitative changes in DNA content during chromatin diminution. Described here cytophotometric method was approbated on five different digital-imaging systems in blood cells(More)
This work has proposed a new theoretical approach to analysis of histograms of DNA content, which are obtained by the method of flow cytometry, in cells of Drosophila melanogaster imaginal discs. The precision of measurements of the DNA amount in G1 and G2(M) phases has been shown to be limited by precision of instrument tuning of zero of the flow(More)
Diffractive optical elements (polypropylene kinoform diffractive lenses, silicon binary diffractive lenses, and silicon beamsplitters) for the terahertz spectral range have been designed and characterized using high-power terahertz radiation of Novosibirsk free electron laser. The effect of an antireflection coating on the silicon elements was studied.
A test of the qualities of polarizing filters was performed for a set of specimens including a bulk Nicol prism, standard polaroids, and special polyvinyl alcohol (PVA)-iodine thin-film filters coated on both sides by vertically oriented carbon nanotubes. The residual transmission of polarizing filters depending on the incidence angle of polarized light was(More)
We propose that multiview wavelets can be used in processing multiview images. The reference functions for the synthesis/analysis of multiview images are described. The synthesized binary images were observed experimentally as three-dimensional visual images. The symmetric multiview B-spline wavelets are proposed. The locations recognized in the continuous(More)
