according to the global fuel crisis, it seems necessary to use alternative fuel instead of gasoline. since the natural gas is cheaper, have higher frequency than gasoline and less pollution, it is a suitable fuel. many efforts have been done in order to replace gasoline with natural gas. one of the methods is to inject natural gas and gasoline fuel simultaneously and to use the benefits of both...

most developing countries have achieved productivity growth in economic sectors like agriculture for more than 30 years. universities and governmental research centers have tried to generate knowledge with direct social and economic effects during these decades. so, productivity and production growth can be attributed to technological changes made possible through investment in agricultural res...

introduction: it is a common protocol to use 201tl for the rest and 99mtc for the stress cardiac spect imaging. theoretically, both types of imaging may be performed simultaneously using different energy windows for each radionuclide. however, a potential limitation is the cross-contamination of scattered photons from 99mtc and collimator x-rays into the 201tl energy window. we used a middle en...

Oligonucleotide microarrays provide a high-throughput method for exploring genomes. In addition to their utility for gene-expression analysis, oligonucleotide-expression arrays have also been used to perform genotyping on genomic DNA. Here, we show that in segregants from a cross between two unrelated strains of Saccharomyces cerevisiae, high-quality genotype data can also be obtained when mRNA...

We address multi-parameter quantum estimation for one-dimensional discrete-time walks and its applications to metrology. use the walker as a probe unknown parameters encoded on coin degrees of freedom. find an analytic expression Fisher information matrix most general operator, show that only two out three can be accessed. also prove resulting two-parameter model is asymptotically classical i.e...

In this paper, the physical layer security aspects of a wireless framework over ????? shadowed (AKMS) fading channel are examined by acquiring closed-form novel expressions average secrecy capacity, secure outage probability (SOP), and strictly positive capacity. The lower bound SOP is derived along with asymptotic expression at high signal-to-noise ratio regime in order to achieve diversity ga...

An optical fiber based well array platform was used for simultaneous, dynamic gene expression monitoring from hundreds of individual live Escherichia coli cells carrying promoter-fluorescent reporter gene fusions. High information content about gene expression kinetics and cell-to-cell gene expression variability can be collected from a single experiment. These data are invaluable for investiga...
