The transition energies and the pressure coefficients of the heavy-hole excitons in a ZnCdSe/ZnSe strained quantum well are studied numerically with consideration of the changes of the barrier heights, the exciton binding energies and other factors.
2. 13C CP/MAS and DD/MAS spectra, as well as 13C Ti and 1H T2 relaxation times of the individual nuclei were measured for the first time of "in-situ stretched" NR samples.
Based on the results of band structure, we have studied the gain spectra of the 2m lasers, the effects of strain and width of the well have been systematically investigated, we have pointed out that the model gain of the lasers can be improved by increasing the compression strain or decreasing the width of the well layers.
The asymptotic expression of dispersion equation of cylindrical Love waves as well radius r 1→∞ consistently tends to the dispersion equation in the horizontal half space case,and cut off frequency tends to zero.
In this paper, we prove the degenerations of Schubert varieties in a minusculeG/P, as well as the class of Kempf varieties in the flag varietySL(n)/B, to (normal) toric varieties.

Well known wonderfulG-varieties are those of rank zero, namely the generalized flag varietiesG/P, those of rank one, classified in [A], and certain complete symmetric varieties described in [DP] such as the famous space of complete conics.

There are two well known combinatorial tools in the representation theory ofSLn, the semi-standard Young tableaux and the Gelfand-Tsetlin patterns.

It is well-known that the ring of invariants associated to a non-modular representation of a finite group is Cohen-Macaulay and hence has depth equal to the dimension of the representation.

As a corollary, we obtain a new proof for Roberts' well-known counterexample in dimension seven.
