the effect of repetitive electrical field stimulation and the response of the guinea-pig and rat ileal longitudinal muscle to single pulse stimulations was examined. single pulse field stimulation produced twitch contraction which was inhibited by repetitive field stimulation (10 hz, 40v, 0.5 msec for 5 m). this inhibition was largely, though never completely, reversed by naloxone. contractions...

,The arrangement of repetitive and non-repetitive sequences was studied in the DNA of Xenopus. Labeled DNA sheared to various fragment lengths was reassociated to C,t 50 (SO’C, O-18 M-Na+) with excess 450 nucleotide fragments of unlabeled DNA, and binding of the labeled DNA to hydroxyapatite was measured. Repetitive sequences monitored in this way are present on about 45% of the 450 nucleotide ...

A within-subjects experimental design examined differences in functional near-infrared spectroscopy (fNIRS) assessment of prefrontal cortex (PFC) activation with two virtual reality (VR) drawing conditions (rote tracing and creative self-expression) without a fragrance stimulus. Participants were healthy adults included 18 women, 6 men: age range = 18–54 years. Findings indicate significant suc...

This paper consists of three sections. In the first section an efficient method is used for decomposition of the canonical matrices associated with repetitive structures. to this end, cylindrical coordinate system, as well as a special numbering scheme were employed. In the second section, divide and conquer method have been used for eigensolution of these structures, where the matrices are in ...
