A measurement of the cross section for the production of an isolated photon in association with jets in proton-proton collisions at a center-of-mass energy root s = 7 TeV is presented. Photons are reconstructed in the pseudorapidity range vertical bar eta(gamma)vertical bar < 1.37 and with a transverse energy E-T(gamma) > 25 GeV. Jets are reconstructed in the rapidity range vertical bar y(jet)vert

When a superconducting sample is submitted to a sufficiently strong external magnetic field, the superconductivity of the material is lost. In this paper we prove that this effect does not, in general, take place at a unique value of the external magnetic field strength. Indeed, for a sample in the shape of a narrow annulus the set of magnetic field strengths for which the sample is superconductin

Objectives: To describe the findings of cardiovascular magnetic resonance (CMR) imaging in patients with pulmonary arterial hypertension (PAH) associated with connective tissue disease (CTD) and in consecutive patients with systemic sclerosis (SSc) without PAH. Methods: The study comprised nine consecutive patients who were admitted for right heart catheterization (RHC) under a suspicion of CTD-PA

Reactive nitrogen (N-r) compounds have different fates in the atmosphere due to differences in the governing processes of physical transport, deposition and chemical transformation. N-r compounds addressed here include reduced nitrogen (NHx: ammonia (NH3) and its reaction product ammonium (NH4+)), oxidized nitrogen (NOy: nitrogen monoxide (NO) + nitrogen dioxide (NO2) and their reaction products)

Objectives To compare different chronic obstructive pulmonary disease (COPD) cost-effectiveness models with respect to structure and input parameters and to cross-validate the models by running the same hypothetical treatment scenarios. Methods COPD modeling groups simulated four hypothetical interventions with their model and compared the results with a reference scenario of no intervention. T

A warmer climate may increase the risk of attacks by insect pests on agricultural crops, and questions on how to adapt management practice have created a need for impact models. Phenological models driven by climate data can be used for assessing the potential distribution and voltinism of different insect species, but the quality of the simulations is influenced by a range of uncertainties. In th

Legislative speeches are an important instrument for parties and members of parliament (MPs) to signal their positions and priorities. This raises the question of who speaks when. We evaluate whether a MP’s presence on the floor depends on his or her gender. We hypothesize that female MPs give in general less speeches in parliament and that this pattern results from debates dealing with “harder” p

Stakeholders of firms have pushed for enterprise risk management (ERM) as a response to flawed risk management and corporate governance systems (Kirkpatrick, 2009). Previous studies explaining why ERM is implemented have been informative but overly simplified. The basic argument presented in this study is that ERM should be seen as a composition of traditional risk management and risk governance,

This paper considers the consequences of a large scale mortality shock arising from a famine or epidemic for long run economic and demographic development. The Great Irish Famine of 1845-1852 is taken as a case-study and is incorporated as an exogenous mortality shock into the type of long-run unified growth theory pioneered by Galor and Weil (1999, 2000), and modelled by Lagerlof (2003a,b) among

Large longitudinal studies on stroke outcome are scarce. The aim of this study was to analyze predictors and changes in functional outcome during the first year poststroke.

Accurate and internationally comparable human papillomavirus (HPV) DNA genotyping is essential for HPV vaccine research and for HPV surveillance. The HPV Laboratory Network (LabNet) has designed international proficiency studies that can be issued regularly and in a reproducible manner. The 2011 HPV genotyping proficiency panel contained 43 coded samples composed of purified plasmids of 16 HPV typ

Despite significant progress in recent years, the cleavage of unstrained C(sp(3) )C(sp(3) ) bonds remains challenging. A CC coupling and cleavage reaction in a PC(sp(3) )P iridium pincer complex is mechanistically studied; the reaction proceeds via the formation of a carbene intermediate and can be described as a competition between α-hydrogen and α-alkyl elimination; the latter process was observ

Hereditary myopathy with early respiratory failure and extensive myofibrillar lesions has been described in sporadic and familial cases and linked to various chromosomal regions. The mutated gene is unknown in most cases. We studied eight individuals, from three apparently unrelated families, with clinical and pathological features of hereditary myopathy with early respiratory failure. The investi

Many empirical studies of the economics of crime focus solely on the determinants thereof, and do not consider the dynamic and cross-sectional properties of their data. As a response to this, the current paper offers an in-depth analysis of this issue using data covering 21 Swedish counties from 1975 to 2010. The results suggest that the crimes considered are non-stationary, and that this cannot b

In this article I argue that On Suffocation relies on paratexts in order to articulate what I take to be its most important message. I foreground a few of these paratexts, especially Facebook postings and a festival Q&A session, in order to illustrate how they contribute to the film’s meaning.

The World Health Organization (WHO) classification of myeloid leukaemia was revised in 2008. It incorporates newly recognized entities and emphasizes the pivotal role of cytogenetic abnormalities. The aim of this study was to evaluate the usability of the WHO classification when applied to a large population-based paediatric acute myeloid leukaemia (AML) cohort. We included children diagnosed with

Deficiencies in the classical pathway of complement activation have some common features but show also great differences. Deficiencies of each of the components (C1q, C1s, C1r, C4 and C2) imply increased susceptibility to bacterial infections. They are also associated with increased risk to develop systemic lupus erythematosus where deficiency of C1q is strongly associated to the disease while C4

Chalcopyrite structures are candidates for efficient intermediate-band solar cells in thin-film technology. Here, we examine a material combination of CuInSe2 dots embedded in CuGaS2 matrix and show that epitaxial growth leads to distinctive tetrahedral nanostructures. Our model calculations provide us with the optimal nanodot size to reach the maximum efficiency-in principle up to 61%. The optima
