The double bubble sign
The double bubble sign in neonates is seen on plain abdominal radiographs in a variety of conditions. It represents gas distended dilated stomach and proximal duodenum, and implies congenital proximal bowel obstruction. A newborn with a double bubble and no distal bowel gas can be presumed to have duodenal atresia and in most cases no further imaging is required. If double bubble is present wit...
متن کاملThe Double Bubble Conjecture
The classical isoperimetric inequality states that the surface of smallest area enclosing a given volume in R3 is a sphere. We show that the least area surface enclosing two equal volumes is a double bubble, a surface made of two pieces of round spheres separated by a flat disk, meeting along a single circle at an angle of 2π/3.
متن کاملBubble dynamics in double-stranded DNA.
We report the first measurement of the dynamics of bubble formation in double-stranded DNA. Fluctuations of fluorescence of a synthetic DNA construct, internally tagged with a fluorophore and a quencher, are monitored by fluorescence correlation spectroscopy. The relaxation dynamics follow a multistate relaxation kinetics, with a characteristic time scale of 50 microseconds. A simple model of b...
متن کاملProof of the Double Bubble Conjecture
The least-area hypersurface enclosing and separating two given volumes in R is the standard double bubble.
متن کاملProof of the Double Bubble Conjecture
We prove that the standard double bubble provides the least-area way to enclose and separate two regions of prescribed volume in R3.
