one of the important factors influencing outdoor insulators performance is pollution phenomenon. the pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of leakage currents (lc) on the insulator surface, which may result in total flashover. the lc characteristics are affected by parameters such as nature and severity of pollution. loca...

UNLABELLED TopoICE-R is a three-dimensional visualization and manipulation software for solving 2-string tangle equations and can be used to model the topology of DNA bound by proteins such as recombinases and topoisomerases. AVAILABILITY This software, manual and example files are available at www.knotplot.com/download for Linux, Windows and Mac.

25 The accuracy of a nested PCR in gastric DNA obtained by string test for the diagnosis of 26 H. pylori infection in asymptomatic children was 94.0%. The cagA-positive toxigenic vacA 27 s1m1 strains were the most prevalent indicating that this population is early colonized by the 28 strains associated with gastric cancer. 29

Extended Abstract In DNA, one section of a string may be reversed. Since this occurs naturally, it would be beneficial to be able to match two strings and note where these reverse subsequences occur. The K-algorithm provides a way to detect reverse substrings. It has worst-case time complexity of O(m3/2n), yet performs quickly in application due to its parallelistic nature.

The accuracy of a nested PCR in gastric DNA obtained by a string test for the diagnosis of Helicobacter pylori infection in asymptomatic children was 94.0%. The cagA-positive toxigenic vacAs1m1 strains were the most prevalent strains, indicating that this population is colonized early by the strains associated with gastric cancer.

We determine the asymptotic limiting probability as m-->infinity that a random string of length m over some alphabet sigma can be determined uniquely by its substrings of length l. This is an abstraction of a problem faced when trying to sequence DNA clones by SBH.

Self-assembling DNA nanostructures are an efficient means of executing parallel molecular computations. However, previous experimental demonstrations of computations by DNA tile self-assembly only allowed for one set of distinct input to be processed at a time. Here, we report the multibit, parallel computation of pairwise exclusive-or (XOR) using DNA "string tile" self-assembly. A set of DNA t...
