We found the linear complexity of quaternary sequences of period over the ring Z_4 . The sequences are based on Whiteman's generalized cyclotomic classes of order four. Also we derived the maximum nontrivial autocorrelation magnitude of the constructed sequences.

Rotational energy levels of axially asymmetric nuclei have been calculated in the manner of Davydov and Filippov, and a comparison with experiment shows good quantitative agreement. It is suggested that agreement may be improved by introducing the Bohr-Mottelson vibration-rotation interaction…

The existing literature on the effect of recycling on a virgin producer’s market power assumes that the entire output of the recyclable product produced in any period is available to the recycling firms as scrap in a subsequent period. The…
