I read with interest the paper by Rumble and colleagues that appeared in an issue of Gynecologic Oncology (Rumble et al., 2015). The authors investigated the circadian rest–activity rhythm disturbances among 60 endometrial cancer patients after surgery, and identified predictors of dysregulated rest–activity rhythms by actigraphy. Namely, the rest–activity dysregulation significantly recovered ...

In the present study, the effect of post-rolling annealing heat treatment on the formation of intermetallic compounds between Al-Cu strips, in the presence of nickel coating on the Cu strips, was investigated. In addition, the effect of post-rolling annealing and intermetallic compounds on the bond strength of Al-Cu strips was evaluated. In order to prepare samples, Cu strips were coated with n...

There is a complicated relation between cold flat rolling parameters such as effective input parameters of cold rolling, output cold rolling force and exit thickness of strips. In many mathematical models, the effect of some cold rolling parameters has been ignored and the outputs have not a desirable accuracy. In the other hand, there is a special relation among input thickness of strips, the ...

We present a bijective proof of the hook length formula for rooted trees based on the ideas of the bijective proof of the hook length formula for standard tableaux by Novelli, Pak and Stoyanovskii [10]. In section 4 we present another bijection for the formula. MR Subject Classification: 05A05,05A15

We present a bijection between 321and 132-avoiding permutations that preserves the number of fixed points and the number of excedances. This gives a simple combinatorial proof of recent results of Robertson, Saracino and Zeilberger [8], and the first author [3]. We also show that our bijection preserves additional statistics, which extends the previous results.
