The most prominent sign of degeneration is that the central cell nucleus produced nuclear vacuoles.

The overlapping cylinder model(OCM) is used in this letter to describe the rapidity (or pseudorapidity) distributions of charged particles produced in nucleus-nucleus collisions at high energies.

The pseudorapidity distributions of charged particles produced in high-energy nucleus-nucleus collisions are studied using Liu's cylinder model.

Fusion is the process of forcing the nuclei of atoms so close together that they fuse into a nucleus of a new element. (Fission, of course, is the opposite: energy produced by splitting nuclei.) The new, fused nucleus weighs less than the original two.

They produced a lively and, to all intents and purposes, normal sheep, known as Dolly, from the nucleus of a mammary-gland cell.
