We describe a method to observe the directional emission of electromagnetic radiation produced by the radiative decay of surface plasmonpolaritons (SPPs) that allows the dispersion of the modes in k-space to be directly visualized. The method presented here opens up the possibility of characterizing the effect of a wide range of surface morphologies on SPP dispersion. As an example we show the ...

The authors discuss the growing evidence that strenuous physical activity is not only healthy for students but improves their academic performance. Based on such research, they argue that schools in the United States need to stop eliminating physicaleducation programs under the current political pressures to emphasize academics and instead to reform traditional physical education. Modern physic...

Ribosomes can read through stop codons in a regulated manner, elongating rather than terminating the nascent peptide. Stop codon readthrough is essential to diverse viruses, and phylogenetically predicted to occur in a few hundred genes in Drosophila melanogaster, but the importance of regulated readthrough in eukaryotes remains largely unexplored. Here, we present a ribosome profiling assay (d...

The English stop voicing contrast is examined in both wordinitial position (via VOT) and word-final position (via the duration of the preceding vowel) in young adult speakers born and brought up in the Shetland Isles. The subjects’ parents were either also from Shetland, from elsewhere in Scotland, or England. All have identical phonemic stop systems, unambiguously so in initial position. The q...

A new technique to reduce the size, improve the rejection in the stop-band of a low-pass filter using modified defected ground structure (DGS) is proposed. An equivalent circuit model is used to study the DGS characteristics. The parameters are extracted by using a simple circuit analysis method. Several comparisons between the EMsimulations and the circuit simulations of the new structure are ...

The new WHO guidelines for the treatment on Tuberculosis (4th edition) has come out in 2010 with several important changes from the previous guideline published in 2003.1 Major progress in global TB control follows the wide spread implementation of DOTs strategy. In 2006 stop TB strategy was launched with the objective of (i) universal access to patient centred treatment and protection of popul...
