A deficit of atmospheric ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ events, consistent with the hypothesis neutrino oscillations, is observed in 5.90 kiloton-year fiducial exposure Soudan 2 detector. An unbinned maximum likelihood analysis $L/E$ distribution has been carried out using Feldman-Cousins prescription. The probability no oscillation $5.8\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}.$ 90% confidence allowed region...
Salmonid alphavirus is the aetological agent of pancreas disease (PD) in marine Atlantic salmon, Salmo salar, and rainbow trout, Oncorhynchus mykiss, with most outbreaks Norway caused by SAV subtype 3 (SAV3). This atypical transmitted horizontally causing a significant economic impact on aquaculture industry. histopathological proteomic study, using an established cohabitational experimental model, investigated correlation between tissue damage during PD number serum proteins associated...
The energy resolution of the barrel part CMS Electromagnetic Calorimeter has been studied using electrons 20 to 250 GeV in a test beam. incident electron's was reconstructed by summing measured arrays 3 × or 5 channels. There no significant amount correlated noise observed within these arrays. For at centre crystals, mean stochastic term be 2.8% and constant 0.3%. electrons' which is contained array depends on its position incidence. variation containment with corrected for distribution...
Upward-going stopping muons initiated by atmospheric νμ and ν¯μ interactions in the rock below Soudan 2 detector have been isolated, together with a companion sample of neutrino-induced single muons, created within detector, which travel downwards exit. The downward-going is consistent atmospheric-neutrino flux prediction, but upward-going exhibits sizable depletion. Both are previously reported neutrino-oscillation results. Inclusion two samples an all-event likelihood analysis, using...
The measurement of scintillation light from the lead tungstate crystals Compact Muon Solenoid (CMS) electromagnetic calorimeter (ECAL) poses a substantial technical challenge, particularly in endcap regions, where radiation levels are highest. photodetectors must be fast, sensitive, radiation-hard, and operate with significant internal gain magnetic field 4 Tesla. measured performance characteristics first batches series production vacuum phototriodes (VPT), developed to satisfy needs CMS,...
Abstract Sequence data from salmonid alphavirus (SAV) strains obtained farmed marine Atlantic salmon, Salmo salar L. , over a 20‐year period between 1991 and 2011 was reviewed to examine the geographical distribution of genetically defined SAV subtypes in twelve regions across Ireland Scotland. Of 160 different salmon examined, 62 belonged subtype 1, 28 2, 34 4, 35 5 1 6. 4 6 were found Ireland, while In majority regions, there clear clustering subtypes, with being dominant overall, as well...
The response of the CMS barrel calorimeter (electromagnetic plus hadronic) to hadrons, electrons and muons over a wide momentum range from 2 350 GeV/c has been measured. To our knowledge, this is widest momenta in which any system studied. These tests, carried out at H2 beam-line CERN, provide wealth information, especially low energies. analysis differences charged pions, kaons, protons antiprotons detailed discussion underlying phenomena are presented. We also show techniques that apply...
Deep underground muon events recorded by the Soudan 2 detector, located at a depth of 2100 m water equivalent, have been used to infer nuclear composition cosmic rays in ``knee'' region ray energy spectrum. The observed multiplicity distribution favors model with substantial proton content $8\ifmmode\times\else\texttimes\fi{}{10}^{5}$--$1.3\ifmmode\times\else\texttimes\fi{}{10}^{7}$ GeV/nucleus.
Sea lice infection is the most expensive disease factor for Atlantic salmon sea-cage farming. For triploid to be accepted as a commercial possibility, investigation of susceptibility sea fundamental milestone. The diploid and with Lepeophtheirus salmonis was examined in tank trial Scotland, Norway cage Scotland.Following single challenge, results indicated significant correlation between fish size number attached lice. Triploid were larger than diploids at smolt stage. In trials, no...
Abstract Diseases which cause skeletal muscle myopathy are some of the most economically damaging diseases in Atlantic salmon, S almo salar L., aquaculture. Despite this, there limited means assessing fish health non‐destructively. Previous investigation serum proteome during pancreas disease ( PD ) has identified proteins that have potential as biomarkers disease. Amongst these proteins, enzyme enolase was selected viable for use a biomarker associated with . Western blot and immunoassay...
