A22 22..22

Four randomised controlled trials (RCTs) and one RCT metaanalysis are featured in the Journal this month. The latter is a review of trials of newer-generation antidepressants and cognitive–behavioural therapy (CBT) for adolescent depression (Dubicka et al, pp. 433–440). In an area of clinical practice plagued by controversy, the authors of this review were able to contribute the finding that ad...

Baron-Cohen et al (pp. 500–509) undertook a study to establish the prevalence of autism-spectrum conditions in Cambridgeshire using two case ascertainment methods.

The Token Flow Model 22 of 22

Dataflow graphs that are strongly consistent and have finite complete cycles can always be scheduled statically and executed in bounded memory. Some strongly consistent graphs without finite complete cycles can also be executed in bounded memory. We have described a clustering technique that can identify such graphs and construct their schedules. However, some perfectly correct graphs may not f...

This paper considers the maximum value of the permanent over the class H(m, n) of n × n Hessenberg, (0, 1)-matrices with m 1’s, and shows that among those matrices that attain the maximum value there exists a matrix with a special form. This special form determines the exact value of the maximum permanent on H(m, n) for certain values of m and n.
