A theoretical study on growth patterns of Ni-doped germanium clusters

Article Abstract:

A systematic investigation of Ni-doped germanium clusters is carried out by using the density functional approach. It is concluded that the average binding energy of the Ni-doped germanium clusters is larger than that of pure [Ge.sub.n] clusters and it could be expected that the encapsulated Ni atom in the Ni[Ge.sub.n] clusters contribute to strengthening the stabilities of germanium clusters.

Clustering in the absence of attractions: density functional theory and computer simulations

Article Abstract:

Several studies are employed to explain the formation of stable clusters of overlapping particles in various interacting systems. The results prove the occurrence of such clustering phenomenon in dense fluid, as well as solid phases.

Dynamics and intrinsic statistical fluctuations of a gene switch

Article Abstract:

The toggle switch gene regulatory network is studied using the master equation. It is found that the time values for system relaxation increased with [omega] having significant phase transition effects.
