Applications of Interval Analysis to Statistical Problems
This paper contribution is about guaranteed numerical methods based on interval analysis and the application of these methods to vast classes of statistical problems. ’Guaranteed’ means here the inner and outer approximations of the sets of interest are obtained, which can be made as precise as desired, at the cost of increasing the computational effort. It thus becomes possible to archieve tas...
متن کاملKaryotype analysis of Rheum palmatum.
Rheum palmatum, one of the source plants of the traditional Chinese medicine rhubarb, is anendemic and endangered species. To our knowledge, this is the first report on the chromosome number and karyotype of this species. Sectioning combined with micrography was used to analyze the karyotype. The following results were obtained: R. palmatum had a stable chromosome number 2n = 22; the basic numb...
متن کاملKaryotype Analysis and Chromosome Banding
Nearly all methods of chromosome banding rely on harvesting chromosomes in mitosis. This is usually achieved by treating cells with tubulin inhibitors, such as colchicine or demecolcine (colcemid), that depolymerize the mitotic spindle and so arrest the cell at this stage. Excessively long incubations with Colcemid result in overcondensed chromosomes that band poorly and moreover some cell type...
متن کاملStatistical Problems in the Analysis of Unequally Spaced Data
The statkiical analysis of irregularly spaced data or the handling of series with missing data asks for particular care because results may be biased In particular, in PTTI applications, two poi& seem to be addressed: the noise analysis in t e r m of Allan or related variances; the estimation of a missing datum on aparticular date. Both these issues are examined in the particular case of the cu...
متن کاملDNA index and karyotype analysis in myelodysplasia.
DNA index (DI) determined by flow cytometry and karyotype determined by conventional methods were obtained on bone marrow samples from 43 haematologically normal subjects and 54 patients with myelodysplastic syndrome (MDS). Twenty one patients had a clonal karyotype abnormality but an additional five had a DI outside the normal range, showing evidence of aneuploidy that was not available from c...
