A method and apparatus for improved performance for reloading translation look-aside buffers in multithreading, multi-core processors. The first rotatable body includes one of a magnet and a hysteresis plate. , greater than 0 degrees and less than 180 degrees, with respect to each other, such that the exposed surfaces together form a concave surface. Further disclosed is a storage medium encoded with a machine-readable computer program code for horizontally structured CADCAM modeling. The compositions and methods disclosed herein provide ethylene polymers with low levels of long chain branching.
