Measurements of spin correlation in top-antitop quark events from proton-proton collisions at root s=7 TeV using the ATLAS detector

Measurements of spin correlation in top quark pair production are presented using data collected with the ATLAS detector at the LHC with proton-proton collisions at a center-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 4.6 fb(-1). Events are selected in final states with two charged leptons and at least two jets and in final states with one charged lepton and at least four

Controlling the growth of epitaxial graphene on metalized diamond (111) surface

The 2-dimensional transformation of the diamond (111) surface to graphene has been demonstrated using ultrathin Fe films that catalytically reduce the reaction temperature needed for the conversion of sp(3) to sp(2) carbon. An epitaxial system is formed, which involves the re-crystallization of carbon at the Fe/vacuum interface and that enables the controlled growth of monolayer and multilayer gra

Reproductive and hormone-related risk factors for epithelial ovarian cancer by histologic pathways, invasiveness and histologic subtypes: Results from the EPIC cohort

Whether risk factors for epithelial ovarian cancer (EOC) differ by subtype (i.e., dualistic pathway of carcinogenesis, histologic subtype) is not well understood; however, data to date suggest risk factor differences. We examined associations between reproductive and hormone-related risk factors for EOC by subtype in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. A

Fungal and bacterial growth following the application of slurry and anaerobic digestate of livestock manure to temperate pasture soils

How land-application of digestate sourced from anaerobic digestion (AD) of animal waste influences the functioning of a mixed pasture agroecosystem is not well characterised, particularly with regard to the response of the actively growing microbial community. We studied the impact of the liquid AD digestate on the decomposer community in two different soils, seeded with two different common grass

Poor sleep as a risk factor for nonsuicidal self-injury in adolescent girls

The purpose of this study was to examine the relation between poor sleep and nonsuicidal self-injury (NSSI), and to test the hypothesis that poor sleep is a risk factor for the development of NSSI in young adolescents. Questionnaire data were used from a 2-wave longitudinal study of a community sample of 881 young Swedish adolescents. The results showed that 7 % of the girls reported poor sleep (n

Associations between serum phthalates and biomarkers of reproductive function in 589 adult men.

Phthalates which are widely used, are ubiquitous in the environment and in some human tissues. It is generally accepted that phthalates exert their toxic action by inhibiting Leydig cell synthesis of testosterone, but in vitro studies have also shown anti-androgenic effects at the receptor level. Some cross-sectional studies have shown inverse associations between urinary levels of phthalates and

Prospective evaluation of long-term safety of dual-release hydrocortisone replacement administered once daily in patients with adrenal insufficiency.

Objective: The objective was to assess the long-term safety profile of dual-release hydrocortisone (DR-HC) in patients with adrenal insufficiency. Design: Randomized, open-label, crossover trial of DR-HC or thrice-daily hydrocortisone for 3 months each (stage 1) followed by two consecutive, prospective, open-label studies of DR-HC for 6 months (stage 2) and 18 months (stage 3) at five university c

The role of individual adaptive practice for sustainable adaptation

Purpose – This paper aims to investigate the strategies used by Swedish citizens to adapt to changing climate variability and extremes. There is an increasing consensus that individual adaptive capacities are critical to successfully adapt to climate change and achieve sustainable development. However, little is known about individual adaptive practices, particularly in developed countries. Design

Heparin-Binding Protein Measurement Improves the Prediction of Severe Infection With Organ Dysfunction in the Emergency Department.

Early identification of patients with infection and at risk of developing severe disease with organ dysfunction remains a difficult challenge. We aimed to evaluate and validate the heparin-binding protein, a neutrophil-derived mediator of vascular leakage, as a prognostic biomarker for risk of progression to severe sepsis with circulatory failure in a multicenter setting.

How migration motives change over distance: evidence on variations across socioeconomic and demographic groups

Migration researchers have long known that the motives for changing place of residence vary over migration distance. Typically, short-distance moves are regarded as motivated by housing considerations and longer-distance moves primarily by employment considerations. Using a large-scale survey on migration motives, this paper explores how migration motives change over migration distance. Particular

The use of ICF in the neurorehabilitation process.

Rehabilitation is often described as a process that starts when the diagnosis is made and continues as long as the person needs interventions. This process comprises four steps: assessment, goal setting, interventions and outcome measurement. In each step, the WHO International Classification of Functioning, Disability and Health (ICF) can be used and the results can be summarized in a rehabilitat

Quantitative oxygen concentration imaging in toluene atmospheres using Dual Imaging with Modeling Evaluation

Fluorescence lifetimes of toluene as a function of oxygen concentration in toluene/nitrogen/oxygen mixtures have been measured at room temperature using picosecond-laser excitation of the S-1-S-0 transition at 266 nm. The data satisfy the Stern-Volmer relation with high accuracy, providing an updated value of the Stern-Volmer slope. A newly developed fluorescence lifetime imaging scheme, called Du

In-line rheometry of particulate suspensions by pulsed ultrasound velocimetry combined with pressure difference method

The in-line rheometer concept based on the combination of the ultrasonic velocity profiling (UVP) technique and pressure difference (PD) measurements was utilized for investigating the influence of particle concentration and size distribution on the rheology of particulate suspensions in pipe flow under realistic industrial process conditions. Well defined model suspensions were used, consisting o

Simultaneous Fusion Moves for 3D-label Stereo

Second derivative regularization methods for dense stereo matching is a topic of intense research. Some of the most successful recent methods employ so called binary fusion moves where the combination of two proposal solutions is computed. In many cases the fusion move can be solved optimally, but the approach is limited to fusing pairs of proposals in each move. For multiple proposals iterative b

Assessment of genetic and pheromonal diversity of the Cydia strobilella species complex (Lepidoptera: Tortricidae)

Combining pheromone trapping and genetic analyses can be useful whentrying to resolve complexes of closely related insect taxa that are difficult to distinguishbased on morphological characters. Nearctic and Palearctic populations of the spruceseed moth, Cydia strobilella L., have been considered taxonomically synonymoussince 1983, but more recent work revealing distinct sex pheromones for Canadia

Slow Aromatic Ring Flips Detected Despite Near-Degenerate NMR Frequencies of the Exchanging Nuclei.

Aromatic ring flips of Phe and Tyr residues are a hallmark of protein dynamics with a long history in molecular biophysics. Ring flips lead to symmetric exchange of nuclei between sites with distinct magnetic environments, which can be probed by NMR spectroscopy. Current knowledge of ring-flip rates originates from rare cases in which the chemical shift difference between the two sites is sufficie

Positron emission tomography in malignancies of the liver, pancreas and biliary tract - indications and potential pitfalls.

Abstract Malignancies of the hepato-pancreatico-biliary (HPB) system are relatively common and generally characterized by a dismal prognosis. Positron emission tomography (PET) is a functional imaging technique that has emerged as an important modality in oncological decision-making. The principal radiopharmaceutical in PET imaging is the glucose analog (18)F-fluorodeoxyglucose, which is able to d

Metacognition and Learning Journals in Higher Education

The studies in higher education have its natural focus on the subject matters of study. This also holds for the master program Technology Management (TM). In addition it is important to complement the students’ academic knowledge with insights about metacognition, i.e. knowledge and understanding of themselves and their own behaviour. The introduction of so-called Learning Journals has proved to b

An Efficient Null Model for Conformational Fluctuations in Proteins

Protein dynamics play a crucial role in function, catalytic activity, and pathogenesis. Consequently, there is great interest in computational methods that probe the conformational fluctuations of a protein. However, molecular dynamics simulations are computationally costly and therefore are often limited to comparatively short timescales. TYPHON is a probabilistic method to explore the conformati
