Isometries and Approximate Isometries

Some properties of isometric mappings as well as approximate isometries are studied. 2000 Mathematics Subject Classification. Primary 46B04. 1. Isometry and linearity. Mazur and Ulam [17] proved the following well-known result concerning isometries, that is, transformations which preserve distances. Theorem 1.1. Given two real normed vector spaces X and Y , let U be a surjective mapping from X ...

Macro-CK and CK-BB Contributing to Sham CK-MB Elevation

A 65-year-old man in whom an inferior vena cava filter had been implanted for deep vein thrombosis was admitted to the cardiology department due to appetite loss and lumbago. Laboratory data showed increased total creatinine kinase (CK, 796 U/L, Picture 1, left) and CK-MB (1,213 U/ L), which exceeded the total CK value. Electrophoresis showed, in addition to an increase in CK-BB, a peak that mi...

A novel platform for detection of CK+ and CK- CTCs.

UNLABELLED Metastasis is a complex, multistep process that begins with the epithelial-mesenchymal transition (EMT). Circulating tumor cells (CTC) are believed to have undergone EMT and thus lack or express low levels of epithelial markers commonly used for enrichment and/or detection of such cells. However, most current CTC detection methods target only EpCAM and/or cytokeratin (CK) to enrich e...

Computing Isometries of Lattices

Introduction. We report on some new ideas to calculate the group of automorphisms of a lattice with a positive definite quadratic form, which lead to an improvement of an algorithm described in [PlP 85] and [Sou 91]. To illustrate the reach of the algorithm e.g. 2 matrices generating the automorphism group of the Leech lattice can be calculated in less than 3 hours on a HP 9000/730 workstation....
