Evidence for νμ → ντ appearance in the CNGS neutrino beam with the OPERA experiment

Abstract: The OPERA experiment is designed to search for $ u_{\mu} \rightarrow u_{\tau}$ oscillations in appearance mode ie through the direct observation of the $\tau$ lepton in $ u_{\tau}$ charged current interactions The experiment has taken data for five years, since 2008, with the CERN Neutrino to Gran Sasso beam Previously, two $ u_{\tau}$ candidates with a $\tau$ decaying into hadrons were observed in a sub-sample of data of the 2008-2011 runs Here we report the observation of a third $ u_\tau$ candidate in the $\tau^-\to\mu^-$ decay channel coming from the analysis of a sub-sample of the 2012 run Taking into account the estimated background, the absence of $ u_{\mu} \rightarrow u_{\tau}$ oscillations is excluded at the 34 $\sigma$ level

Analyses of a Polyhydroxyalkanoic Acid Granule-Associated 16-Kilodalton Protein and Its Putative Regulator in the pha Locus of Paracoccus denitrificans

Abstract: The polyhydroxyalkanoic acid (PHA) granule-associated 16-kDa protein (GA16 protein) of Paracoccus denitrificans was identified, and its corresponding gene was cloned and analyzed at the molecular level. The N-terminal amino acid sequence of GA16 protein revealed that its structural gene is located downstream from the PHA synthase gene (phaCPd) cloned recently (S. Ueda, T. Yabutani, A. Maehara, and T. Yamane, J. Bacteriol. 178:774-779, 1996). Gene walking around phaCPd revealed two new open reading frames (ORFs) possibly related to PHA synthesis, one of which was the phaPPd gene, encoding GA16 protein, and the other was the phaRPd gene, encoding a protein that is putatively involved in the regulation of the expression of phaPPd. Overproduction of PhaPPd was observed in Escherichia coli carrying phaPPd, but the overproduction was not observed in the presence of phaRPd. Coexpression of phaPPd and PHA biosynthesis genes in E. coli caused increases in both the number of poly-(3-hydroxybutyric acid) (PHB) granules and PHB content and caused decreases in both the size of the granules and the molecular weight of PHB. GA16 protein was considered a phasin protein. The phaRPd gene had significant similarities to stdC, a possible transcriptional factor of Comamonas testosteroni, as well as to other ORFs of unknown function previously found in other PHA-synthetic bacteria.
