We define a complex R RrJ J of graded modules on a d-dimensional simplicial complex β¬, so that the top homology module of this complex consists of piecewise Ε½ . polynomial functions splines of smoothness r on the cone of β¬. In a series of w Ε½ .
We construct a hierarchy of spectral sequences for a filtered complex under a Ε½ . left-exact functor. As applications we prove 1 the existence of a Leray spectral Ε½ . sequence for de Rham cohomology, 2 the equivalence of this sequence with the ''usual'' Leray spectral spectral sequence under the com
Completely Arbitrary Regional Volume Excitation (CARVE) is a technique that enables the excitation of complex shapes in two and three dimensions. It is based on the train of interleaved short RF pulses and gradient steps. For on-resonance magnetization, the CARVE parameters (amplitudes and phases of
