Indications of suppression of excited ÎĽ states in Pb-Pb collisions at âsNN = 2.76TeV
This is the pre-print version of the Published Article which can be accessed from the link below.A comparison of the relative yields of ÎĽ resonances in the Îź+Îź- decay channel in Pb-Pb and pp collisions at a center-of-mass energy per nucleon pair of 2.76 TeV is performed with data collected with the CMS detector at the LHC. Using muons of transverse momentum above 4ââGeV/c and pseudorapidity below 2.4, the double ratio of the ÎĽ(2S) and ÎĽ(3S) excited states to the ÎĽ(1S) ground state in Pb-Pb and pp collisions, [ÎĽ(2S+3S)/ÎĽ(1S)]Pb-Pb/[ÎĽ(2S+3S)/ÎĽ(1S)]pp, is found to be 0.31-0.15+0.19(stat)Âą0.03(syst). The probability to obtain the measured value, or lower, if the true double ratio is unity, is calculated to be less than 1%

Pineapple translation factor SUI1 and ribosomal protein L36 promoters drive constitutive transgene expression patterns in Arabidopsis thaliana
The availability of a variety of promoter sequences is necessary for the genetic engineering of plants, in basic research studies and for the development of transgenic crops. In this study, the promoter and 5' untranslated regions of the evolutionally conserved protein translation factor SUI1 gene and ribosomal protein L36 gene were isolated from pineapple and sequenced. Each promoter was translationally fused to the GUS reporter gene and transformed into the heterologous plant system Arabidopsis thaliana. Both the pineapple SUI1 and L36 promoters drove GUS expression in all tissues of Arabidopsis at levels comparable to the CaMV35S promoter. Transient assays determined that the pineapple SUI1 promoter also drove GUS expression in a variety of climacteric and non-climacteric fruit species. Thus the pineapple SUI1 and L36 promoters demonstrate the potential for using translation factor and ribosomal protein genes as a source of promoter sequences that can drive constitutive transgene expression patterns
