Search for Standard Model Higgs boson in the two-photon final state in ATLAS

We report on the search for the Standard Model Higgs boson decaying into two photons based on proton-proton collision data with a center-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. The dataset has an integrated luminosity of about 1.08 fb-1. The expected cross section exclusion at 95% confidence level varies between 2.0 and 5.8 times the Standard Model cross section over the diphoton mass range 110 - 150 GeV. The maximum deviations from the background-only expectation are consistent with statistical fluctuations.Comment: Presented at the 2011 Hadron Collider Physics symposium (HCP-2011), Paris, France, November 14-18 2011, 3 pages, 4 figure

A limnological assessment of Russell Pond, Woodstock, New Hampshire

A limnological survey was conducted during 17-18 September, 1998 to characterize the trophic state of Russell Pond, a 15.8 Ha natural Lake located in Woodstock, Grafton County, New Hampshire. Physical, biological and chemical parameters were measured to assess the health of the lake and changes from previous studies. Russell Pond is oligotrophic with high Secchi disk depths (13.8 m), low phosphorus levels (3.8 µg L1) and low Chlorophyll a concentration (0.5 µg L-1). Peridinium (Dinophyceae) dominated (64%) the net phytoplankton. Calanoid copepods (Diaptomidae) constituted 87.5% of the crustacean zooplankton. The lake is at risk for acidification because of low acid neutralizing capacity (1.2 mg CaCO3 L-1) and low pH (5.6) in the deep water. Russell Pond has exceptionally high water clarity due to the low phytoplankton density and low water color (6.9 CPU). Water quality of the lake has been stable over the past few years. Compared to data from four other New Hampshire lakes, Russell Pond is the most oligotrophic of the lakes, followed by Pleasant Lake and Stonehouse Pond. Great Pond and Townhouse Pond were the most mesotrophic of the lakes

Ongoing Clinical Trials of the Pleiotropic Effects of Statins

Jean Davignon1, Lawrence A Leiter21Clinical Research Institute of Montreal, Montreal, QC, Canada; 2Division of Endocrinology and Metabolism, St Michael’s Hospital, Toronto, ON, CanadaBackground: The multiple effects (ie, pleiotropic effects of statins) have received increasing recognition and may have clinical applicability across a broad range of cardiovascular and noncardiovascular conditions. Objective: To determine the relevance and significance of ongoing clinical trials of the pleiotropic effects of statins, focusing on nonlipid effects. Method: Ongoing trials were identified through personal communication, reports presented at scientific meetings (2000–2004), and queries made to AstraZeneca, Bristol-Myers Squibb Co, Merck & Co, Novartis, and Pfizer, manufacturers of the currently marketed statins. Published trials and other source material were identified through electronic searches on MEDLINE (1990–2003), abstract books, and references identified from bibliographies of pertinent articles. Eligible studies were the clinical trials of statins currently under way in which primary or secondary outcomes included the statins’ nonlipid (ie, pleiotropic) effect(s). Data were extracted and trial quality was assessed by the authors. Results: Of the 22 ongoing trials of the nonlipid effects of statins identified, 10 assessed inflammatory markers and plaque stabilization, 4 assessed oxidized low density lipoprotein/vascular oxidant stress, 3 assessed end-stage renal disease, 3 assessed fibrinogen/viscosity, 2 assessed endothelial function, 2 assessed acute coronary syndrome, 2 assessed aortic stenosis progression, and 1 each assessed hypertension, osteoporosis, ischemic burden, Alzheimer’s disease, multiple sclerosis, and stroke (outcomes often overlapped). Conclusion: Given the excellent safety and tolerability of statins as a class, full exploration of their pleiotropic effects has the potential to provide additional benefits to many patients.

Paper Session I-C - Integrated Resource Management

The 45th Space Wing is responsible for providing range and launch processing support services to its customers using the launch site at Cape Canaveral Air Station and the Eastern Range. At the same time, funding for providing this support and maintaining the necessary infrastructure continues to be constrained. Government and contractor manning for operating the Eastern Launch Site and the Eastern Range has declined by roughly ten percent in the last five years. The government, along with industry, is being asked to do more with less and do it faster. New customers no longer spend four to five years introducing a launch program. Instead, a new commercial customer may expect to make a launch date two years after initial program introduction. To accomplish the 45th Space Wing’s mission of “Ensure National Strength Through Assured Access To Space” and achieve its vision: “To be the World’s Premier Gateway To Space” require that the funding and resources the Wing does receive be used as efficiently and effectively as possible. Effective and efficient use of the Wing’s resources to accomplish its mission depends upon information— information about those resources and how they are to be used

Simultaneous expression of CD4 and CD8 antigens by a substantial proportion of resting porcine T lymphocytes

The existence of four subpopulations in resting porcine T lymphocytes is documented. In addition to the two known subpopulations which are typified by a mutually exclusive expression of either the CD8 or the CD4 differentiation antigen, CD4-CD8+ and CD4+CD8- T lymphocytes, respectively, two unusual subpopulations were prominent not only in peripheral blood, but also in lymphoid tissues: CD4-CD8- T lymphocytes expressing neither of these antigens and CD4+CD8+ T lymphocytes coexpressing both antigens. While CD4+CD8+ lymphoblasts have been found also in other species, resting T lymphocytes with that phenotype are without precedent among all species analyzed to date. This unique composition of the porcine T lymphocyte population has to be taken into consideration when the swine is used as a large animal model in experimental medicine

Development of a high strength Al-Mg2Si-Mg-Zn based alloy for high pressure die casting

A high strength Al-Mg2Si-Mg-Zn based alloy has been developed for the application in high pressure die casting to provide improved mechanical properties. The effect of various alloying elements on the microstructure and mechanical properties including yield strength, ultimate tensile strength and elongation of the alloy was investigated under the as-cast and heat-treated conditions. The typical composition of the high strength alloy has been optimised to be Al-8.0wt%Mg2Si-6.0wt%Mg-3.5wt%Zn-0.6wt%Mn (Al-11.0wt%Mg-2.9wt%Si-3.5wt%Zn-0.6wt%Mn) with unavoidable trace impurities. The mechanical properties of the alloy were enhanced by a quick solution treatment followed by ageing treatment. The improved tensile properties were at a level of yield strength over 300MPa, the ultimate tensile strength over 420MPa and the elongation over 3% assessed using international standard tensile samples made by high pressure die casting. The microstructure of the die-cast alloy consisted of the primary α-Al phase, Al-Mg2Si eutectics, AlMgZn intermetallics and α-AlFeMnSi intermetallics under the as-cast condition. The AlMgZn intermetallic compound was dissolved into the Al-matrix during solution treatment and subsequently precipitated during ageing treatment for providing the effective improvement of the mechanical properties.The financial support is gratefully acknowledged for the Engineering and Physical Sciences Research Council (EPSRC) (Project number: EP/I038616/1), Technology Strategy Board (TSB) (Project number: 101172) and Jaguar Land Rover (JLR), United Kingdom
