We present results for the QCD next-to-leading order (NLO) calculation of single-top t-channel production in the 4-flavour scheme, interfaced to Parton Shower (PS) Monte Carlo programs according to the POWHEG and MC@NLO methods. Comparisons between the two methods, as well as with the corresponding process in the 5-flavour scheme are presented. For the first time results for typical kinematic dist
We present predictions for the SM-Higgs-pair production channels of relevance at the LHC: gluon-gluon fusion, VBF, and top-pair, W, Z and single-top associated production. All these results are at the NLO accuracy in QCD, and matched to parton showers by means of the MC@NLO method; hence, they are fully differential. With the exception of the gluon-gluon fusion process, for which a special treatme
Objective:Sleep duration has been related to overweight in children, but determinants of sleep duration are unclear. The aims were to investigate the association between sleep duration and childhood overweight adjusted for family characteristics and unhealthy behaviours, to explore determinants of sleep duration and to determine with sleep competing activities.Method:A cross-sectional study was ca
Unesterified radioactive cholesterol, both bound to serum lipoproteins and dispersed in ethanol-saline, was injected into bile fistula and intact rats. Due to phagocytosis, mainly by the liver macrophages, intravenously injected cholesterol in ethanol-saline disappears from the bloodstream significantly faster than lipoprotein-bound cholesterol. Soon after the initial phagocytosis, the particulate
We use observations of M3 to constrain thermohaline mixing. This is done by matching [C/Fe] and [N/Fe] along the RGB of M3. We find our models can explain observations if it is assumed there is a spread of ∼ 0.3 - 0.4 dex in [C/Fe] in the stars in M3 from their birth. We reproduce the full spread in [C/Fe] at the tip of the RGB. Thermohaline mixing can produce a significant change in [N/Fe] as a f
In a population of Blue Tits, Parus caeruleus, we performed two different food provisioning experiments; one starting before clutch initiaition and one starting when the first eggs were laid. We assessed the effect of these feeding experiments on four fitness—related factors, viz., laying date, clutch size, egg mass, and onset of incubation. Given that breeding birds are food and energy constraine
The value of a quality-adjusted life-year (QALY) and the value of a statistical injury (VSI) are important measures within health economics and transport economics. Several studies have, therefore, estimated people's willingness to pay (WTP) for these estimates, but most results show scale insensitivity. The 'original' chained approach (CA) is a method developed to mitigate this problem by combini
The excitatory amino acid glutamate has been suggested to be an important mediator of the selective CA1 hippocampal damage which follows transient cerebral ischemia. In order to evaluate the possible involvement of altered glutamate receptor regulation in the expression of the delayed neuronal necrosis following ischemia, we have determined the density of glutamate receptor subtypes in the rat hip
Human rights are meant to be universal, indivisible, and inalienable. They are legal norms that claim to reflect urgent moral concerns, and to protect human beings by mere virtue of their humanity. As such they are held to be universal, in that they apply to all human beings regardless of their background and nationality; they are inalienable, in that all human beings are born with them and they
Research infrastructures such as biobanks are increasingly important for science and society. This paper focuses on the transition of biobanks from being a research tool of individual research groups to complex, internationally networked research infrastructures supporting large-scale biomedical investigations, and the challenges that this change poses for governance in relation to management, fun
Background: Embolic stroke of undetermined source (ESUS) identifies patients with cryptogenic ischemic stroke presumed due to embolism from several unidentified sources. Among patients with recent ESUS, we sought to determine independent predictors of recurrent ischemic stroke during treatment with aspirin or rivaroxaban and to assess the relative effects of these treatments according to risk. Met
Introduction: The clinical diagnosis of Parkinson’s disease (PD) is based on the identification of bradykinesia and at least one additional feature among rigidity, resting tremor and postural instability. These clinical features have been estimated to appear when at least 50% of the nigral dopamine neurons and 70% of putaminal dopamine tissue contents are lost [1]. Dopaminergic imaging suggests th
Thanks to Bruno Galantucci, “experimental semiotics” is usually nowadays taken to mean the study of “novel forms of communication which people develop when they cannot use pre-established communication systems”. In spite of Galantucci’s claim to have picked the label because it was free, it has actually been used in different ways at least twice before: by Colin Ware, who takes it to be involved w
The purpose of the current paper is to outline how gestures can contribute to the study of some key issues in language development. Specifically, we (1) briefly summarise what is already known about gesture in the domains of first and second language development, and development or changes over the life span more generally; (2) highlight theoretical and empirical issues in these domains where gest
We present a study of tunable high-order sum and difference frequency mixing in the 7-70 eV range, in xenon, argon and neon. We mix the light from a terawatt, subpicosecond titanium-sapphire laser and that from a tunable optical parametric generator. The radiation generated through mixing processes involves absorption or emission of one or Mo photons from the weak tunable source. The relative stre
