The invariant imbedding T-matrix (IIM T-matrix) model is regarded as one of the most promising models for calculating scattering parameters non-spherical particles. However, IIM needs to be iterated along radial direction when T-matrix, which involves complex calculations such matrix inversion and multiplication. Therefore, how improve its computational efficiency an important problem solved. F...

Recent studies showed that p34(SEI-1), also known as TRIP-Br1 or SEI-1, plays a dual role in the regulation of cell-cycle progression. It exhibits the transactivation activity and regulates a number of genes required for G1/S transition, while it also binds and activates cyclin-dependent kinase 4 (CDK4) independent of the inhibitory activity of p16. The goals of this paper are to further dissec...
