Searches for exclusively produced W boson pairs in the process pp(γγ)→pW+W-p and an exclusively produced Higgs boson in the process pp(gg)→pHp have been performed using e±μ final states. These measurements use 20.2 fb-1 of pp collisions collected by the ATLAS experiment at a center-of-mass energy s=8 TeV at the LHC. Exclusive production of W+W- consistent with the Standard Model prediction is foun

Measurements of the anisotropic flow coefficients v2{Ψ2},v3{Ψ3},v4{Ψ4}, and v4{Ψ2} for identified particles (π±,K±, and p+p) at midrapidity, obtained relative to the event planes Ψm at forward rapidities in Au + Au collisions at sNN=200GeV, are presented as a function of collision centrality and particle transverse momenta pT. The vn coefficients show characteristic patterns consistent with hydrod

Three- and four-pion Bose-Einstein correlations are presented in pp,p-Pb, and Pb-Pb collisions at the LHC. We compare our measured four-pion correlations to the expectation derived from two- and three-pion measurements. Such a comparison provides a method to search for coherent pion emission. We also present mixed-charge correlations in order to demonstrate the effectiveness of several analysis pr

We hypothesized that in a normal healthy population changes in several ECG parameters together might reliably characterize the functional age of the heart. Data from 377 healthy subjects (209 men, 168 women, aged 4 to 75 years) were included in the study. In all subjects, ECG recordings (resting 5-minute 12-lead high fidelity ECG) were evaluated via custom software programs to calculate up to 120

Background: Lund is one of the two tertiary referral centers for pediatric cardiac surgery in Sweden, with nearly 350 surgical procedures every year. We performed a retrospective analysis of newborns and infants with transposition of the great arteries (TGA) operated with arterial switch (ASO) during the past 10 years. Methods: a single-institution retrospective analysis of nearly 100 newborns and

Introduction: Cardiopulmonary bypass (CPB) surgery remains associated with significant cardiovascular morbidity in both pediatric and adult patients but the mechanisms are not fully clarified. Abnormalities in coronary flow and function have beensuggested to play an important role. A few prior studies suggested protective effects on coronary and myocardial function by short intravenous (i.v.) infu

Polarity is a shared feature of most cells. In epithelia, apical-basal polarity often coexists, and sometimes intersects with planar cell polarity (PCP), which orients cells in the epithelial plane. From a limited set of core building blocks (e.g. the Par complexes for apical-basal polarity and the Frizzled/Dishevelled complex for PCP), a diverse array of polarized cells and tissues are generated.

The purpose of the present study is to evaluate the effect of rate control drugs on the AV node characteristics during atrial fibrillation (AF) using a model-based approach. A statistical model of the AV nodal function is employed, defined by parameters which characterize the arrival rate of atrial impulses, the refractoriness of the fast and the slow AV-nodal pathway and the probability of atrial

The atrioventricular (AV) node plays a central role during atrial fibrillation (AF).We have recently proposed a statistical AV node model defined by parameters characterizing the arrival rate of atrial impulses, the probability of an impulse choosing the slower of the two AV nodal pathways, the refractory periods of the pathways, and the prolongation of refractory periods. All model parameters are

This paper introduces a number of advancements of our recently proposed model of atrioventricular (AV) node function during atrial fibrillation (AF). The model is defined by parameters characterizing the arrival rate of atrial impulses, the probability of an impulse choosing either one of the two AV nodal pathways, the refractory periods of these pathways, and their prolongation. In the updated mo

This brief presents an on-chip memory subsystem for massive multiple-input-multiple-output (MIMO) baseband processing at the base station. In massive MIMO systems, the required memory bandwidth and capacity are orders of magnitude higher than those used in conventional wireless systems, due to the large number of serving antennas. These are further combined with design targets on low access latenc

Samlingen av medeltida kyrklig konst från Skåne på Historiska museet i Lund är unik sett till både kvantitet och kvalitet. Här finns nära en tredjedel av landskapets kyrkor representerade och träskulpturen omspänner allt från verk av lokala konstnärer till firade mästare från kontinenten. På museets tredje våning kan besökaren se det mesta och det bästa i en närmast tidlös installation, designad a

The collection of medieval Scanian church art at the Historical museum of Lund is unique as to both quantity and quality. Here, nearly a third of the churches in the province are represented and the wood sculpture encompasses everything from works by local artists to celebrated masters from the continent. On the second floor of the museum the visitor can see most and the best of it in a nearly tim

"This account of the Historical Museum and Archaeological Research at Lund University 1805-2005 consists of two parts; a reprint of the history of the Museum including the Archaeological Department until 1984, published that year, and a part comprimising the development during the subsequent twenty years. It describes and discusses the changges and, if possible, the causes of change.The author, Be

Human milk provides a very wide range of nutrients and bioactive components, including immune factors, human milk oligosaccharides, and a commensal microbiota. These factors are essential for interconnected processes including immunity programming and the development of a normal infant gastrointestinal microbiome. Newborn immune protection mostly relies on maternal immune factors provided through
