Distance to Ck hypersurfaces

hypersurfaces: The vector distance functions

We present a novel method for representing and evolving objects of arbitrary dimension. The method, called the Vector Distance Function (VDF) method, uses the vector that connects any point in space to its closest point on the object. It can deal with smooth manifolds with and without boundaries and with shapes of diierent dimensions. It can be used to evolve such objects according to a variety...

Some Properties of the Volume Distance to Hypersurfaces

In this paper we consider the volume distance from a point to a convex hypersurface M ⊂ R, which is defined as the minimum (N + 1)-volume of a region bounded by M and a hyperplane through the point. We describe some of its properties, among them the centroid property, which says that any point is the centroid of its minimal section. We discuss the differentiability of the volume distance and sh...

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...

Circulating CK-MB and CK-BB isoenzymes after prostate resection.

We studied the effect of prostate resection on serum creatine kinase (EC 2.7.3.2) and lactate dehydrogenase (EC 1.1.1.27) isoenzymes in 22 patients. Two hours after their operations, two-thirds of these patients had increased total creatine kinase activity. The MB isoenzyme was demonstrated in sera of 66% of the patients and the BB isoenzyme in 76%. MB content varied from 1 to 7% of total creat...
