Measurement of the W+W− production cross section in pp collisions at a centre-of-mass energy of s=13 TeV with the ATLAS experiment

The production of opposite-charge W-boson pairs in proton–proton collisions at s=13 TeV is measured using data corresponding to 3.16 fb−1 of integrated luminosity collected by the ATLAS detector at the CERN Large Hadron Collider in 2015. Candidate W-boson pairs are selected by identifying their leptonic decays into an electron, a muon and neutrinos. Events with reconstructed jets are not included

Diet Analysis of Wetland Passerine Nestlings Using Neck Collars or Faecal Sampling Produces Similar Results

Two methods are commonly used to study the diet of nestling passerines: the neck collar method and faecal sampling. Most studies apply either method, however, few methodological studies comparing both methods exist and are mainly limited to farmland birds. Furthermore, existing methodological studies only include high-level taxonomic diet categories. Here, we compared both methods using two wetlan

Search for new high-mass phenomena in the dilepton final state using 36 fb−1 of proton-proton collision data at √s=13 TeV with the ATLAS detector

A search is conducted for new resonant and non-resonant high-mass phenomena in dielectron and dimuon final states. The search uses 36.1 fb−1 of proton-proton collision data, collected at s=13 TeV by the ATLAS experiment at the LHC in 2015 and 2016. No significant deviation from the Standard Model prediction is observed. Upper limits at 95% credibility level are set on the cross-section times branc

Multi-modal sensory feedback system for upper limb amputees

Providing sensory feedback for myoelectric prosthetic users can not only increase the manipulation ability but can also introduce a feeling of embodiment. Previous research has demonstrated the feasibility of providing mechanotactile or vibrotactile feedback on the remaining stumps of amputees. To improve the recognition rate and reduce mental work load when identifying stimulation patterns, we pr

Nano-Scratching resistance of high-chromium white cast iron and its correlation with wear of cBN tool in machining

In this paper, a nano-scratch testing approach was used to measure and evaluate the abrasion wear resistance of high-chromium white cast irons in order to understand the wear mechanism in the interaction between the high-chromium white cast iron and the cBN cutting tool during the machining process. Scratch testing was performed on a nanoindentation instrument using a diamond indenter as the scrat

Development and application of high-speed laser visualization techniques in combustion research

In order to fulfil the requirements of available energy resources, there is a great need to obtain a sustainable and environmentally friendly energy utilization using combustion processes. In order to do this, it is of utmost importance to utilize non-intrusive diagnostic techniques with high spatial and temporal resolution which can characterize the combustion process and also validate combustion

Changes in drug spending for different age groups during the 1990s? : Evidence from Sweden

The objective of this review is to examine how drug spending in different age groups changed during the 1990s. Time series analysis of registered data on prescription drug spending were performed, along with two decompositions, one of which was spending in three components: price, quantity (defined daily dose) and residual. The size of the residual is a measure of the impact of changes in drug tre

More detailed data does not always raise the costs : Experience from a Swedish cost of alcohol study

The aim is to investigate the effect of availability and level of detail of data on cost estimates of alcohol consumption. Using the recent Swedish cost of alcohol study as baseline, limitations on data are applied, forming two models. The costs of alcohol in Sweden are re-estimated in the two models and compared to the baseline, to establish the magnitude and direction of the bias resulting from

Medical net cost of low alcohol consumption - a cause to reconsider improved health as the link between alcohol and wage?

Background: Studies have found a positive effect of low/moderate alcohol consumption on wages. This has often been explained by referring to epidemiological research showing that alcohol has protective effects on certain diseases, i.e., the health link is normally justified using selected epidemiological information. Few papers have tested this link between alcohol and health explicitly, including

HIV/AIDS-GDP Nexus? : Evidence from panel-data for African countries

To test potential bilateral causalities relation between HIV-AIDS mortality and GDP, we propose a simple Granger noncausality test for heterogeneous panel data models. 44 African countries are selected for annual pooled data from 1990 to 2009. Results are presented for the heterogeneous noncausality hypothesis (HENC), which tests, for each cross-section unit, the nullity of all the coefficients of

Swedish experience-based value sets for EQ-5D health states

PurposeTo estimate Swedish experience-based value sets for EQ-5D health states using general population health survey data.MethodsApproximately 45,000 individuals valued their current health status by means of time trade off (TTO) and visual analogue scale (VAS) methods and answered the EQ-5D questionnaire, making it possible to model the association between the experience-based TTO and VAS values

Health behavior in the Nordic countries

This paper provides a descriptive analysis of the level of and change in cigarette smoking, excessive alcohol consumption and body weight in Nordic countries and compares them with non-Nordic OECD countries. Our results show that the average prevalence of daily smokers is significantly lower for Nordic countries compared to non-Nordic countries. Four out of five Nordic countries are below the non-

Frequency and intensity of alcohol consumption : New Evidence from Sweden

There is an increasing body of evidence that the intensity in which alcohol is drunk is of greater concern than the frequency or overall quantity consumed. This paper provides an extensive analysis of the demand for alcohol as measured by total quantity, frequency, and intensity. A unique large sample of cross-sectional data from Sweden 2004–2011 allows reduced-form alcohol demand equations to be

Do kidney transplantations save money? – A study using a before–after design and multiple register-based data from Sweden

Background: The health care costs of kidney transplantation and dialysis are generally unknown. This study estimates the Swedish health care costs of kidney transplantation and dialysis over 10 years from a health care perspective.Method: A before–after design was used, in which the patients served as their own controls. Health care costs the year before transplantation were assumed to continue in

VSC-HVDC application to improve the long-term voltage stability

This paper concerns the VSC-HVDC application to improve the long-term voltage stability. For this purpose the NORDIC32 test system is considered. All necessary dynamics to study the long-term voltage stability are included in the test system. An appropriate control strategy for VSC-HVDC is proposed in the paper. The goal is to reach the best condition from long-term voltage stability perspective w

A large eddy simulation study of bluff body flame dynamics approaching blow-off

The mechanisms leading to blowoff were investigated numerically by analyzing bluff body stabilized flame at two conditions: a condition far from blowoff to a condition just prior to blowoff. Large eddy simulations have been used to capture the time dependent, three-dimensional evolution of the field. The results were first validated to available experimental data, showing very good agreement for t
