The ATLAS (one of two general purpose detectors at the LHC) Transition Radiation Tracker (TRT) is the outermost of the three tracking subsystems of the ATLAS Inner Detector. It is a large straw-based detector and contains about 350,000 electronics channels. The performance of the TRT as tracking and particularly particle identification detector strongly depends on stability of the operation parame
Objective The effect of a common polymorphism in the Growth Hormone (GH) receptor (d3-GHR) gene on growth, metabolism and body composition was examined in short children born small for gestational age (SGA) on GH treatment. Design In 96 prepubertal, short SGA children treated with high-dose GH (67 μg/kg/day) in the NESGAS study, insulin sensitivity (IS), insulin secretion and disposition index (DI
Objectives: Dysglycemia and glycemic variability are associated with poor outcomes in critically ill patients. Targeted temperature management alters blood glucose homeostasis. We investigated the association between blood glucose concentrations and glycemic variability and the neurologic outcomes of patients randomized to targeted temperature management at 33°C or 36°C after cardiac arrest. Desig
The current study provides a social constructionist approach to crisis communication in the Chinese context. Crisis communication is viewed as a form of strategic communication, involving multiple stakeholders in situations that are dependent on context, space and time. This approach provides a much-needed path for investigating and understanding crisis communication practices in contemporary Chin
Introduction: It has traditionally been believed that early repolarization (ER) is benign. Significant association between ER and sudden cardiac arrest due to idiopathic ventricular fibrillation was recently found in a large cohort of adult survivors of sudden cardiac arrest. In some prior studies, unexplained syncope has been linked to risk of sudden death, but the mechanisms remain speculative.W
Background: Although transposition of the great arteries (TGA) accounts for less than 5% of congenital heart disease, the clinical course is often dramatic with need for early diagnosis and careful preoperative care as well as advanced surgical correction and postoperative support. Since 1993, Lund is one of the two tertiary referral centers for pediatric cardiac surgery in Sweden, with nearly 400
Objectives: Endothelial cells of coronary arteries undergo apoptosis in patients with coronary artery disease. Carotid artery ultrasound studies show that after acute infections intima media thickness is increased. The possible effects of infections on endothelial cell apoptosis and the presence of apoptosis in early life remain unknown. Methods: Chlamydia pneumonia was inoculated three times at t
A search for the standard model Higgs boson produced in association with a vector boson with the decay H→ττ is presented. The data correspond to 20.3 fb-1 of integrated luminosity from proton-proton collisions at s=8 TeV recorded by the ATLAS experiment at the LHC during 2012. The data agree with the background expectation, and 95% confidence-level upper limits are placed on the cross section of t
Introduction: Four-dimensional (4D) flow magnetic resonance imaging (MRI) enables kinetic energy (KE) quantification of intraventricular blood flow. In this study we aimed to quantify the KE in in patients with univentricular heart and to assess the change in the KE after different types of interventions. Methods: 4D flow MRI was acquired in patients with Fontan circulation (n=12; median age 12, r
Background: Hypertrophic cardiomyopathy (HCM) is the most common monogenic cardiac disorder and the leading cause of sudden cardiac death in the young. Although in a majority of HCM cases there are gene mutations coding for sarcomere proteins, the onset for the clinical consequences of these mutations are difficult to predict, as these mutations do not show any clear relationship to the degree of
This paper presents measurements of W±Z production in pp collisions at a center-of-mass energy of 8 TeV. The gauge bosons are reconstructed using their leptonic decay modes into electrons and muons. The data were collected in 2012 by the ATLAS experiment at the Large Hadron Collider and correspond to an integrated luminosity of 20.3 fb-1. The measured inclusive cross section in the detector fiduci
This paper presents a new method of reconstructing the individual charged and neutral hadrons in tau decays with the ATLAS detector. The reconstructed hadrons are used to classify the decay mode and to calculate the visible four-momentum of reconstructed tau candidates, significantly improving the resolution with respect to the calibration in the existing tau reconstruction. The performance of the
A search for Higgs boson production in association with a pair of top quarks (tt¯ H) is performed, where the Higgs boson decays to bb¯, and both top quarks decay hadronically. The data used correspond to an integrated luminosity of 20.3 fb−1 of pp collisions at √s = 8 TeV collected with the ATLAS detector at the Large Hadron Collider. The search selects events with at least six energetic jets and
