Fathers are expected to play an increasing part in the care of children, but fathers are not automatically included in studies of early childhood. In this paper we present Swedish fathers' experiences of child health care. In the study, a total of 237 out of 279 (85%) fathers of small children were telephone interviewed using a structured questionnaire. As many as 165 (70%) had visited the child h
This Letter reports a measurement of the W W production cross section in root s = 7 TeV pp collisions using data corresponding to an integrated luminosity of 1.02 fb(-1) collected with the ATLAS detector. Using leptonic decays of oppositely charged W bosons, the total measured cross section is sigma (pp -> W W) = 54.4 +/- 4.0 (stat.) +/- 3.9 (syst.) +/- 2.0 (lumi.) pb, consistent with the Standard
The jet structure in events with Drell-Yan-produced W bosons is discussed, and a new model for describing such an event is presented. The model is shown to explain recent measurements of the W-jet rapidity correlation and predicts a transverse energy flow at high W rapidities (corresponding to probing small-x partons in one of the incoming protons) higher than conventional parton cascade event gen
We present a study of lνbb and l++l-bb production at hadron colliders. Our results, accurate to the next-to-leading order in QCD, are based on automatic matrix-element calculations performed byMadLoop andMadFKS, and are given at both the parton level, and after the matching with the Herwig event generator, achieved with aMC@NLO. We retain the complete dependence on the bottom-quark mass, and inclu
Recently a slight tension between data and predictions has been reported in tt¯ W production by both the CMS and ATLAS collaborations. We revisit the theoretical predictions for this process, focussing on the following two effects. We disentangle various effects that lead to asymmetries among the leptonic decay products of the (anti-)top quarks and W bosons, for which we find that the spin correla
The W and Z boson production was measured via the muonic decay channel in proton-lead collisions at sNN=5.02 TeV at the Large Hadron Collider with the ALICE detector. The measurement covers backward (−4.46 < ycms < −2.96) and forward (2.03 < ycms < 3.53) rapidity regions, corresponding to Pb-going and p-going directions, respectively. The Z-boson production cross section, with dimuon invariant mas
Background: The development of factor (F) VIII neutralizing alloantibodies (inhibitors) is a major complication of treatment with FVIII concentrates in hemophilia A and the etiology is still poorly understood. The low-affinity Fc gamma receptors (Fc gamma R), which are expressed on immune cells, provide an important link between cellular and humoral immunity by interacting with IgG subtypes. Genet
The possibility of positronium induced free volume cavity expansion in some polymers above the glass transition temperature was investigated using experimental positron annihilation lifetime data from the literature for polydimethylsiloxane, polyisobutylene, and polybutadiene as function of temperature. The results suggest that free volume sites can expand towards an equilibrium size, determined a
Popular Abstract in Swedish Den fria volymen i en polymer är kopplad till flera fundamentala fysikaliska egenskaper som till exempel densitet, viskositet och gas diffusivitet. De fysikaliska egenskaperna hos polymerer i närheten av, eller i kontakt med, en solid yta har visats vara väsentligt olika dess bulkegenskaper. De fysikaliska egenskaperna hos polymerer i närheten av, eller i kontakt med, yThe free volume in polymers is coupled to several important physical properties, such as density, viscosity and gas diffusivity. The physical properties of polymers close to a solid surface have been shown to be significantly perturbed as compared to their bulk state. The behavior of polymers close to surfaces comes into play within the field of polymer composites, where the properties of the inte
This article provides an analysis on how disruptive innovation is spurred by the dynamics of digital and analogue networks in the sharing economy. The analysis builds on a free guided tour company in Copenhagen. Data is collected in a bottom-up reiterative process, drawing on theories on disruptive innovation and network theory. Between 2013 and 2016, one of the free tour companies in Copenhagen w
We present an experimental study of controlled Free Induction Decay (FID) in the extreme ultraviolet regime excited by High-order Harmonics. The control is done by applying a delayed infrared pulse.
Jury and Martin establish an analogue of the classical inner-outer factorization of Hardy space functions. They show that every function f in a Hilbert function space with a normalized complete Pick reproducing kernel has a factorization of the type f = ϕg, where g is cyclic, ϕ is a contractive multiplier, and ||f|| = ||g||. In this paper we show that if the cyclic factor is assumed to be what we
Aim: To investigate self-reported needs for care, support and treatment among persons who frequently visit psychiatric emergency rooms (PERs).Design: A cross-sectional design. Qualitative and quantitative data were collected using an interview-based manual. Qualitative data were analysed using content analysis, whereas quantitative data were analysed using descriptive, non-parametric statistical t
