Algorithms such as Kleinberg’s HITS algorithm, the PageRank algorithm of Brin and Page, and the SALSA algorithm of Lempel and Moran use the link structure of a network of web pages to assign weights to each page in the network. The weights can then be used to rank the pages as authoritative sources. These algorithms share a common underpinning; they find a dominant eigenvector of a nonnegative ...

The local linear embedding algorithm (LLE) is a non-linear dimension-reducing technique, widely used due to its computational simplicity and intuitive approach. LLE first linearly reconstructs each input point from its nearest neighbors and then preserves these neighborhood relations in the low-dimensional embedding. We show that the reconstruction weights computed by LLE capture the high-dimen...

This paper proposes an approach to estimate the parameters of AC–DC boost power factor corrector converter that includes EMI filter. To this end, once topology was known, values passive elements were identified from measurements at input and output terminals converter. The based on trust region nonlinear least squares algorithm. steady-state transient signals input/output acquired non-intrusive...

das erlernen einer zweiten sprache neben der erstsprache, n?mlich der muttersprache, gilt als zweitspracherwerb. man kann verschiedene formen des zweitspracherwerbs unterscheiden und zwar je nachdem, in welchem alter, auf welche weise, mit welchen zielen und bis zu welchem grad der sprachbeherrschung die neue sprache gelernt wird. aber es spielt eine besonders gro?e rolle, ob diese neue sprache...

Quantification of genetic modification (GM) is often undertaken to test for compliance with the European Union GM labeling threshold in food. Different control laboratories will often use common validated methods, but with different models of real-time PCR machines. We performed two separate ring trials to evaluate the relative precision and accuracy of different types of real-time PCR machines...

Functional studies of resident microglia require molecular tools for their genetic manipulation. Here we show that microRNA-9-regulated lentiviral vectors can be used for the targeted genetic modification of resident microglia in the rodent brain. Using transgenic reporter mice, we demonstrate that murine microglia lack microRNA-9 activity, whereas most other cells in the brain express microRNA...

Dale Pearse School of Agricultural & Resource Economics, University of Western Australia A choice modeling approach was used to identify consumer preferences for various hypothetical forms of genetic modification in beer, using a sample from Western Australia. It was found that respondents were equally averse to first-generation modification in either plants or microorganisms but were willing t...
