Search for diphoton events with large missing transverse momentum in 7 TeV proton-proton collision data with the ATLAS detector
No full textATLAS Collaboration Contributor: Paul Douglas Jackson and Nitesh Soni of School of Chemistry and Physics, University of Adelaide, Adelaide, Australia.A search for diphoton events with large missing transverse momentum has been performed using proton-proton collision data at s=7 TeV recorded with the ATLAS detector, corresponding to an integrated luminosity of 4.8 fb-1. No excess of events was observed above the Standard Model prediction and model-dependent 95% confidence level exclusion limits are set. In the context of a generalised model of gauge-mediated supersymmetry breaking with a bino-like lightest neutralino of mass above 50 GeV, gluinos (squarks) below 1.07 TeV (0.87 TeV) are excluded, while a breaking scale Λ below 196 TeV is excluded for a minimal model of gauge-mediated supersymmetry breaking. For a specific model with one universal extra dimension, compactification scales 1/R<1.40 TeV are excluded. These limits provide the most stringent tests of these models to date. © 2012 CERN.ATLAS Collaboratio
Search for a heavy top-quark partner in final states with two leptons with the ATLAS detector at the LHC
No full textAtlas Collaboration contributor: Paul Douglas Jackson and Nitesh Soni of School of Chemistry and Physics, University of Adelaide, North Terrace Campus, 5000, SA, Australia. Extent: 35p.The results of a search for direct pair production of heavy top-quark partners in 4.7 fb⁻¹ of integrated luminosity from pp collisions at √s = 7 TeV collected by the ATLAS detector at the LHC are reported. Heavy top-quark partners decaying into a top quark and a neutral non-interacting particle are searched for in events with two leptons in the final state. No excess above the Standard Model expectation is observed. Limits are placed on the mass of a supersymmetric scalar top and of a spin-1/2 top-quark partner. A spin-1/2 top-quark partner with a mass between 300 GeV and 480 GeV, decaying to a top quark and a neutral non-interacting particle lighter than 100 GeV, is excluded at 95% confidence level.The ATLAS Collaboratio
Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in root s = 7 TeV pp collisions with the ATLAS detector
No full textATLAS Collaboration Contributor: Paul Douglas Jackson and Nitesh Soni of School of Chemistry and Physics, University of Adelaide, Adelaide, Australia.A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb⁻¹ of √s = 7TeV proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results.The ATLAS Collaboratio
ATLAS search for new phenomena in dijet mass and angular distributions using pp collisions at root s=7 TeV
No full textATLAS Collaboration Contributor: Paul Douglas Jackson of SLAC National Accelerator Laboratory, Stanford CA, United States of America. Nitesh Soni of School of Chemistry and Physics, University of Adelaide, Adelaide, Australia. Extent: 45p.Mass and angular distributions of dijets produced in LHC proton-proton collisions at a centre-of-mass energy √s=7 TeV have been studied with the ATLAS detector using the full 2011 data set with an integrated luminosity of 4.8 fb⁻¹. Dijet masses up to ~ 4.0 TeV have been probed. No resonance-like features have been observed in the dijet mass spectrum, and all angular distributions are consistent with the predictions of QCD. Exclusion limits on six hypotheses of new phenomena have been set at 95% CL in terms of mass or energy scale, as appropriate. These hypotheses include excited quarks below 2.83 TeV, colour octet scalars below 1.86 TeV, heavy W bosons below 1.68 TeV, string resonances below 3.61 TeV, quantum black holes with six extra space-time dimensions for quantum gravity scales below 4.11 TeV, and quark contact interactionsThe ATLAS Collaboratio
The story of the Soni Ventorum Wind Quintet
No full textThesis (D. Mus. Arts)--University of Washington, 2000The Soni Ventorum Wind Quintet has been the wind quintet-in-residence at the University of Washington School of Music since 1968. Officially founded in 1962, when its members were on the faculty of the Conservatory of Music of Puerto Rico, the group has had a long and stable history. Through their concerts, tours, and recordings, the Soni Ventorum Wind Quintet has established an international reputation. Over the years, many distinguished composers have written works especially for the Soni Ventorum, thus expanding the repertoire of the wind quintet.This study traces the history of the Soni Ventorum Wind Quintet mainly through interviews with the quintet members themselves. This history includes antecedent quintets in which members of the Soni Ventorum Wind Quintet participated (namely, a student quintet at the Curtis Institute, The American Wind Ensemble of Vienna, and the U.S. Seventh Army Symphony Wind Quintet). It covers the founding of the Soni Ventorum Wind Quintet in 1962 at the Conservatory of Music in Puerto Rico through their tenure from 1968 through the present as the wind quintet-in-residence at the University of Washington in Seattle. It gives an account of the establishment of the Soni Ventorum's recording career, their approach to sound and ensemble, their many tours, participation in festivals and competitions, and personnel. The study details the Soni Ventorum's collaborations with colleagues at the University of Washington School of Music, especially the many composers who wrote pieces for the group. One chapter covers ensemble pieces that have been written for the members of the Son! Ventorum Wind Quintet, while another presents wind quintet and quartet arrangements that were prepared by the quintet members themselves. The final chapter provides biographies of the members of the Soni Ventorum Wind Quintet.The Introduction to the study is a brief history of wind quintets. The study concludes with detailed appendices cataloguing the Soni Ventorum Wind Quintet's repertoire, concerts, residencies, tours and a complete discography.At the time of this writing, the author is aware of no other work detailing the history of an established wind quintet

Relationship between IQ, DQ and SQ in young children with hearing impairment
No full textThe data was collected from 40 young children with hearing impairment (YCHI) and their caregivers at the Department of Clinical Psychology, in a Government teaching Institute of Speech and Hearing. These 40 YCHI underwent the SFBT, the GDT, the DST, and the VSMS. YCHI were referred for assessment of intelligence prior to cochlear implant surgery. Assent from the caregivers of the participants was taken. A positive correlation was found between the GDT IQ and the SQ (r= 0.558, p < 0.01), the GDT IQ and the DQ (r= 0.431, p < 0.01), the SQ and the DQ (r=0.576, p< 0.01). On comparing the means of the SFBT IQ, the GDT IQ, the DQ and the SQ, the mean of the SFBT IQ was the highest and the mean of the DQ was the lowest. The DQ was 35 and 31 points lesser than the SFBT IQ and the SQ respectively. SFBT IQ score was higher (3 points) than the SQ
A brief analysis of corrosion-induced degradation in metallic materials: a challenge in additive manufacturing
No full textAdditive manufacturing (AM) has revolutionised the production of metal components, opening up the possibility of designing and producing parts previously unattainable with traditional manufacturing techniques. Nevertheless, concerns remain regarding these AM-produced parts’ long-term durability and reliability. Several studies have shown that material degradation (corrosion) ranks among the foremost factors responsible for constraining the performance of metal parts. It is well-established that corrosion undermines the functionality of a component by deteriorating its mechanical characteristics, including ductility, fatigue resistance, as well as its physical and elastic properties. This review delves into the various corrosion-induced degradation mechanisms that affect metallic materials, particularly those fabricated using the Additive Manufacturing (AM) process. Furthermore, the review highlights the importance of proper post-processing techniques as a key factor in improving the durability and reliability of AM components, offering valuable insights for readers to strengthen their AM practices
