Nanodiscs are self-assembled nanostructures composed of a belt protein and a small patch of lipid bilayer, which can solubilize membrane proteins in a lipid bilayer environment. We present a method for the alignment of a well-defined two-dimensional layer of nanodiscs at the air-water interface by careful design of an insoluble surfactant monolayer at the surface. We used neutron reflectivity to d

This study examines the influence of health conditions experienced during the individual's first year of life on the incidence of sickness absence during adulthood. Using a sample of approximately 9000 biological siblings from 17 countries of origin and living in Sweden during the time period 1981-1991, sibling fixed effect models are estimated. This approach is combined with the use of an exogeno

We develop a general recipe for constructing orthogonal bases for the calculation of color structures appearing in QCD for any number of partons and arbitrary N-c. The bases are constructed using hermitian gluon projectors onto irreducible subspaces invariant under SU(N-c). Thus, each basis vector is associated with an irreducible representation of SU(N-c). The resulting multiplet bases are not on

Hexachlorobenzene (HCB) is a persistent environmental fungicide that may disrupt androgen regulation. The aim of this study was to investigate associations between HCB levels and biomarkers of male reproductive function. 589 spouses of pregnant women from Greenland, Poland and Ukraine were enrolled between 2002 and 2004. The men provided semen and blood samples and were interviewed. HCB was measur

A substantial fraction of the price for a supermirror neutron guide system is the shielding, which is needed because of the gamma radiation produced as a result of neutron absorption in the supermirror layers. Traditional coatings have been made of nickel-titanium heterostructures, but Ni and Ti also have a fairly high absorption cross section for cold and thermal neutrons. We examine a number of

In this paper we summarize the properties of nu (dyn) and discuss briefly how the results can be interpreted in terms of a simple pair-production model. The ideas are then illustrated in detail with a PYTHIA simulation study of forward-backward correlations in pp collisions.

Purpose: Here, we describe an integrated bioinformatics, functional analysis, and translational pathology approach to identify novel miRNAs involved in breast cancer progression. Experimental Design: Coinertia analysis (CIA) was used to combine a database of predicted miRNA target sites and gene expression data. Using two independent breast cancer cohorts, CIA was combined with correspondence anal

The theoretical point of departure of this paper is that the perspective of political myth adds to the understanding of political developments in Russia. The upcoming Olympic Winter Games in Sochi in 2014 are discursively constructed as a manifestation of Russia's return to great power status. In official Russian discourse, there is an encounter between the Russian great power myth and the myth of

Measurements of the production of jets of particles in association with a Z boson in pp collisions at root s = 7 TeV are presented, using data corresponding to an integrated luminosity of 4.6 fb(-1) collected by the ATLAS experiment at the Large Hadron Collider. Inclusive and differential jet cross sections in Z events, with Z decaying into electron or muon pairs, are measured for jets with transv

Activated microglial cells, which are the resident macrophages of the central nervous system, surround amyloid beta-plaques in Alzheimer's disease (AD) brains. Inflammation including microglial activation may contribute in AD pathogenesis, and biomarkers for this process may thus be of value to study AD pathogenesis and might facilitate development of therapies targeting these cells. We therefore

Several studies suggest that hormonal mechanisms may be associated with the development of uveal melanoma. Therefore, the association between the risk of uveal melanoma and exposure to hormonal exposures was investigated in a case-control study from nine European countries. Incident cases of uveal melanoma were frequency-matched to population and hospital controls by country, age, and sex. Female

In situ laser diffraction, scanning electron microscopy (SEM) imaging, and thermography have been used to investigate particle formation and particle size distribution of alkyl ketene dimer (AKD) produced by rapid expansion of supercritical solution (RESS). The investigated RESS process is based on an earlier reported method to prepare superhydrophobic coatings. Spray distance, pre-expansion tempe

Published prospective pediatric exercise intervention studies are short term and use skeletal traits as surrogate endpoints for fractures, whereas other reports infer exercise to be associated with more trauma and fractures. This prospective, controlled exercise intervention study therefore followed both skeletal traits and fracture risk for 36 months. Fractures were registered in children aged 7

PURPOSE: Whether coffee modulates response to endocrine therapy in breast cancer patients is currently unknown. The CYP1A2 and CYP2C8 enzymes contribute to tamoxifen and caffeine metabolism. The purpose was to investigate the impact of coffee consumption on tumor characteristics and risk for early events in relation to breast cancer treatment and CYP1A2 and CYP2C8 genotypes. METHODS: Questionnaire

Browning of inland waters has been noted over large parts of the Northern hemisphere and is a phenomenon with both ecological and societal consequences. The increase in water color is generally ascribed to increasing concentrations of dissolved organic matter of terrestrial origin. However, oftentimes the increase in water color is larger than that of organic matter, implying that changes in the c

We show how to compute the two-loop sunset integrals at finite volume, for non-degenerate masses and non-zero momentum. We present results for all integrals that appear in the Chiral Perturbation Theory (chi PT) calculation of the pseudoscalar meson masses and decay constants at next-to-next-to-leading order, including the case of Partially Quenched chi PT. We also provide numerical implementation

This Letter presents measurements of the polarization of the top quark in top-antitop quark pair events, using 4: 7 fb(-1) of proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider at root s = 7 TeV. Final states containing one or two isolated leptons ( electrons or muons) and jets are considered. Two measurements of alpha P-l, the product of the leptonic spin-a

The growing interest in the possibility of applying stem-cell therapies to gastroenterological diseases is outlined. Some promising results have been reported, but more research is needed in view of the uncertainties and knowledge gaps that still exist. The ethical issues raised by this kind of research are then indicated and classified. Three problematic kinds of situation are outlined: experimen

Within-category induction is the projection of a generic property from a class (Apples are sweet) to a subtype of that class (Chinese apples are sweet). The modifier effect refers to the discovery reported by Connolly et al., that the subtype statement tends to be judged less likely to be true than the original unmodified sentence. The effect was replicated and shown to be moderated by the typical
