    2016 Update of the ttˉH\mathrm{t\bar{t}H} Multilepton Analysis at s=13\sqrt{s} = 13 TeV

    Full text link
    The latest results from the search for a Standard Model Higgs boson produced in association with a top quark pair (ttˉH\mathrm{t\bar{t}H}) at s=13\sqrt{s} = 13 TeV decaying to final states with multiple leptons is presented using the 2016 dataset from the CMS experiment. The Higgs decays into either WW*, ZZ*, or ττ\tau\tau, and the top quark pair decays considered are either fully leptonic, or semi-leptonic. The leptons defining the final states are muons and/or electrons. The overall analysis strategy, as well as new techniques with respect to the 2015 results are outlined.Comment: 9th International Workshop on Top Quark Physics Olomouc, Czech Republic, September 19-23, 2016. arXiv admin note: substantial text overlap with arXiv:1612.0770

    The political economy of the Brazilian model of agricultural development: Institutions versus sectoral policy

    Get PDF
    AbstractThis paper analyzes the transition of Brazilian agriculture from low productivity and backwardness to its current status as a major player in international markets. Long-term investment in local agricultural technology was a crucial determinant of this transformation, but the impact of agricultural policy along this path was highly convoluted, often causing more distortions than progress. We highlight the importance of the underlying institutional setting on the impact of agricultural policy. The remarkable transformation in Brazilian agriculture only really emerged when inclusive and sustainable institutions created a fiscal, monetary and political environment in which those policies could succeed

    Biooptical variability in the Greenland Sea observed with the Multispectral Airborne Radiometer System (MARS)

    A site-specific ocean color remote sensing algorithm was developed and used to convert Multispectral Airborne Radiometer System (MARS) spectral radiance measurements to chlorophyll-a concentration profiles along aircraft tracklines in the Greenland Sea. The analysis is described and the results given in graphical or tabular form. Section 2 describes the salient characteristics and history of development of the MARS instrument. Section 3 describes the analyses of MARS flight segments over consolidated sea ice, resulting in a set of altitude dependent ratios used (over water) to estimate radiance reflected by the surface and atmosphere from total radiance measured. Section 4 presents optically weighted pigment concentrations calculated from profile data, and spectral reflectances measured in situ from the top meter of the water column; this data was analyzed to develop an algorithm relating chlorophyll-a concentrations to the ratio of radiance reflectances at 441 and 550 nm (with a selection of coefficients dependent upon whether significant gelvin presence is implied by a low ratio of reflectances at 410 and 550 nm). Section 5 describes the scaling adjustments which were derived to reconcile the MARS upwelled radiance ratios at 410:550 nm and 441:550 nm to in situ reflectance ratios measured simultaneously on the surface. Section 6 graphically presents the locations of MARS data tracklines and positions of the surface monitoring R/V. Section 7 presents stick-plots of MARS tracklines selected to illustrate two-dimensional spatial variability within the box covered by each day's flight. Section 8 presents curves of chlorophyll-a concentration profiles derived from MARS data along survey tracklines. Significant results are summarized in Section 1

    The Evolution of the American Real Estate Society

    Get PDF
    The American Real Estate Society (ARES) started with the need for real estate academics to increase their applied research and teaching skills and grew rapidly as research practitioners realized the benefits of working with academics in their field. From its humble beginnings, ARES has grown to be the largest organization of real estate researchers in the world and has spawned a number of new real estate societies on a number of continents. The history of the ARES approach to being innovative and inclusive to all real estate thought leaders is chronicled in this article by two authors who met at one of the early pre-ARES meetings and have been both real estate academics and practitioners in their careers.

    Helicopter main-rotor speed effects: A comparison of predicted ranges of detection from the aural detection program ICHIN and the electronic detection program ARCAS

    Get PDF
    NASA LaRC personnel have conducted a strudy of the predicted acoustic detection ranges associated with reduced helicopter main rotor speeds. This was accomplished by providing identical input information to both the aural detection program ICHIN 6, (I Can Hear It Now, version 6) and the electronic acoustic detection program ARCAS (Assessment of Rotorcraft Detection by Acoustics Sensing). In this study, it was concluded that reducing the main rotor speed of the helicopter by 27 percent reduced both the predicted aural and electronic detection ranges by approximately 50 percent. Additionally, ARCAS was observed to function better with narrowband spectral input than with one-third octave band spectral inputs and the predicted electronic range of acoustic detection is greater than the predicted aural detection range

    A rounded picture is what we need : rhetorical strategies, arguments, and the negotiation of change in a UK hospital trust

    Get PDF
    This article is concerned with the introduction of the agenda of New Public Management (NPM) within the board of a UK Hospital Trust: West London Hospital (WLH). We discuss the literature on New Public Management, including its limitations for analysing the organizational reality of implementing NPM. But we will also be drawing on discourse theory and the literature on rhetoric. The main argument in this article is that in order to understand the reality of the NPM paradigm, we need to study the rhetorical strategies of protagonists involved in the negotiation of the NPM agenda. Rhetorical strategies are means of making general viewpoints more convincing, for example, by comparing 'our' organization with similar organizations. Rhetorical strategies show patterns, which reappear in conversations and arguments made by protagonists. Specifically, we identified three rhetorical strategies justifying why and what kind of a more 'rounded picture' was required: widening the argument to include national productivity comparisons with other hospitals; widening the argument away from a narrow focus on finance toward a strategic and political perspective; and, lastly, widening the argument to look at innovation in the whole clinical process

    [Review of] Jane Katz. Artists in Exile: American Odessey [Odyssey]

    Get PDF
    The major accomplishment of this collection of first-person reminiscences and third-person authorial interjection is its presentation of an impressive collection of imported talents, all of whom suffer (often gladly) the intellectual and spiritual privations of the West in exchange for its relative economic and social largess. To paraphrase Churchill, democracy (read capitalism ) is the worst form of government except for all the others. This book says this geometrically, with the lines and curves formed by the various interviews forming a final, however planular, shape
