Chimpanzee stool associated circular virus is a single stranded DNA virus isolated from chimpanzee stool. The genome is ~2.6 kilobases in length and encodes two open reading frames (ORFs). The larger of the ORFs encodes the replicase gene and the other the putative capsid protein. A stem-loop and TATA boxes are present...

World tube In physics, a world tube is the path of an object which occupies a nonzero region of space (nonzero volume) at every moment in time, as it travels through 4-dimensional spacetime. That is, as it propagates in spacetime, a world tube traces out a three-dimensional volume for every moment in time. The world tu...

Bel–Robinson tensor In general relativity and differential geometry, the is a tensor defined in the abstract index notation by: Alternatively, where formula_3 is the Weyl tensor. It was introduced by Lluís Bel in 1959. The is constructed from the Weyl tensor in a manner analogous to the way the electromagnetic stress–e...

Buoyant density centrifugation (also isopycnic centrifugation or equilibrium density-gradient centrifugation) uses the concept of buoyancy to separate molecules in solution by their differences in density. Historically a caesium chloride (CsCl) solution was often used, but more commonly used density gradients are sucro...

Peeling theorem In general relativity, the peeling theorem describes the asymptotic behavior of the Weyl tensor as one goes to null infinity. Let formula_1 be a null geodesic in a spacetime formula_2 from a point p to null infinity, with affine parameter formula_3. Then the theorem states that, as formula_3 tends to in...

Synge's world function In general relativity, is an example of a bitensor, i.e. a tensorial function of pairs of points in the spacetime. Let formula_1 be two points in spacetime, and suppose formula_2 belongs to a convex normal neighborhood of formula_2 so that there exists a unique geodesic formula_4 from formula_2 t...

Geroch's splitting theorem In the theory of causal structure on Lorentzian manifolds, Geroch's theorem or (first proved by Robert Geroch) gives a topological characterization of globally hyperbolic spacetimes. Let formula_1 be a globally hyperbolic spacetime. Then formula_1 is strongly causal and there exists a global ...

Pearl vortex In superconductivity, a is a vortex of supercurrent in a thin film of type-II superconductor, first described in 1964 by Judea Pearl. A is similar to Abrikosov vortex except for its magnetic field profile which, due to the dominant air-metal interface, diverges sharply as 1/formula_1 at short distances fro...
