We have followed this case for 10 years.Up to now, the outcome of this operation is very good, with no tumor recurrenceand good function. According to the experiences, the authors raised the technicalindexes of design, the indications, incision, surgical procedures, and warnings.展开更多

In our paper we prove results concerning G-decorrelated decompositions of functions in l2(G). These G-decorrelated decompositions are obtained using the G-convolution either by the irreducible characters of the group G or by an orthogonal projection onto the matrix entries of the irreducible representations of the group G. Applications of these G-decorrelated decompositions are given to crossover designs in clinical trials, in particular the William’s 6×3?design with 3 treatments. In our example, the underlying group is the symmetric group S3.展开更多
