We analyze the energy and angular momenta of the two-spin spiky string moving on the AdS3×S with NS-NS field. Due to the infinite boundary of the AdS spacetime the solution will extend to infinity and it appears the divergences. After adding the counter terms we then obtain the dispersion relation of the corresponding giant magnon and see how the background field produces the correction terms. ...

Type IIA toroidal orientifolds offer a promising toolkit for model builders, especially when one includes not only the usual fluxes from NS-NS and R-R field strengths, but also fluxes that are T-dual to the NS-NS three-form flux. These new ingredients are known as metric fluxes and non-geometric fluxes, and can help stabilize moduli or can lead to other new features. In this paper we study two ...

In this paper we consider superstring propagation in a nontrivial NS-NS background. We deform the world sheet stress tensor and supercurrent with an infinitesimal Bμν field. We construct the gauge-covariant super-Poincaré generators in this background and show that the Bμν field spontaneously breaks spacetime supersymmetry. We find that the gauge-covariant spacetime momenta cease to commute wit...

Bacterial nucleoid-associated proteins (NAPs) form nucleoprotein complexes and influence the expression of genes. Recent studies have shown that some plasmids carry genes encoding NAP homologs, which play important roles in transcriptional regulation networks between plasmids and host chromosomes. In this study, we determined the distributions of the well-known NAPs Fis, H-NS, HU, IHF, and Lrp ...

The phylogenetic relationships of the hemagglutinin (HA) and non-structural (NS) genes from avian influenza (AI) H5 subtype viruses of North American origin are presented. Analysis of the HA genes of several previously uncharacterized isolates from waterfowl and turkeys provided clear evidence of significant sequence variation and existence of multiple virus clades or sub-lineages, maintained i...

The complete nucleotide sequence of the NS mRNA of vesicular stomatitis virus (New Jersey serotype) was established from two cDNA clones spanning the entire coding region of the mRNA. The gene is 856 nucleotides long and can code for a polypeptide of 274 amino acids. Comparison with the nucleotide sequence of the NS gene of the Indiana serotype revealed only 41% sequence homology. The deduced a...

The influenza A virus pandemic of 1918-1919 resulted in an estimated 20-40 million deaths worldwide. The hemagglutinin and neuraminidase sequences of the 1918 virus were previously determined. We here report the sequence of the A/Brevig Mission/1/18 (H1N1) virus nonstructural (NS) segment encoding two proteins, NS1 and nuclear export protein. Phylogenetically, these genes appear to be close to ...

Noonan syndrome (NS) and NS-related disorders (Cardio-Facio-Cutaneous (CFC) syndrome, Costello syndrome, LEOPARD (Lentigines, ECG conduction abnormalities, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth and sensory neural Deafness) syndrome) share common clinical features characterized by unique facial features, postnatal growth failure, psychomotor retardati...

The genome of the autonomous parvovirus minute virus of mice (MVM) is organized in two overlapping transcription units: the genes coding for the two non-structural proteins (NS-1 ad NS-2) are transcribed from a promoter (P04) located at map unit 4, whereas the promoter controlling the capsid protein genes (P39) lies at map unit 39. We studied the effect of viral proteins on the activity of the ...
