摘要：
The electronic structure of the 13-atom Rh cluster is studied with the structure model optimized by Estiu and Zerner using the discrete variational local-spin density-functional method. The magnetic moment per atom of the cluster is calculated to be 0.54 mu(B), in good agreement with experimental measurements (0.48 +/- 0.13)mu(B). It confirms our previous assumption that the structural distortion of the Rh-13 cluster from a perfect icosahedron to its ground state geometry decreases its magnetic moment and makes the theoretical calculation close to the experimental measurement.

摘要：
QCD three-loop vacuum graphs are calculated in Feynman gauge. All the temperature-dependent divergences are extracted by using dimensional regularization. Ultraviolet divergences are shown to cancel with each other and the ir divergences remain uncanceled.

摘要：
It is shown that for a magnetized accretion disk under Narayan's revised viscosity law, three oscillating modes exist. Of these, the viscous mode is always stable, the inward and outward magneto-acoustic modes are usually unstable. These results may be useful for understanding the light variation in BL Lac objects, Seyfert galaxies, and quasars.
摘要：
The stability of the sonic point in an isothermal accretion disc is examined for the case in which a new revised viscosity is adopted. From this viscosity, it follows that at a sonic point T

τ/r). The results show that the sonic point is a saddle and stable against small amplitude perturbations. Finally, we discuss these results.

摘要：
The kinetic equations for quark-gluon plasma (QGP) are studied beyond the linear response theory, and the nonlinear eigenfrequency shift owing to the non-Abelian interaction of the color eigenmodes in a spatially uniform QGP is calculated.
