Improved parton showers at large transverse momenta

Several methods to improve the parton-shower description of hard processes by an injection of matrix-element-based information have been presented over the years. In this article we study (re)weighting schemes for the first/hardest emission. One objective is to provide a consistent matching of the POWHEG next-to-leading order generator to the Pythia shower algorithms. Another is to correct the def

Back-pulsing as an energy-saving method in the microfiltration of milk

Extended shelf-life milk can be produced by a combination of microfiltration and pasteurisation. However, due to the need for high cross-flow velocity during microfiltration, the energy consumption is high. One way of decreasing the energy demand during microfiltration is to use back-pulsing for fouling control. Microfiltration was performed in constant flux mode on skim milk to measure the foulin

Everyday hassles and uplifts among women on long-term sick-leave due to stress-related disorders

A balance between different experiences of occupations in everyday life is important for well-being. The study aim was to describe hassles and uplifts in everyday occupations among women on long-term sick-leave due to stress-related disorders. The sample consisted of 77 women and experiences were collected by the THU-5 instrument. The statements were analysed using quantitative content analysis. D

A novel atlas of gene expression in human skeletal muscle reveals molecular changes associated with aging.

Although high-throughput studies of gene expression have generated large amounts of data, most of which is freely available in public archives, the use of this valuable resource is limited by computational complications and non-homogenous annotation. To address these issues, we have performed a complete re-annotation of public microarray data from human skeletal muscle biopsies and constructed a m

Upregulation of contractile endothelin type B receptors by lipid-soluble cigarette smoking particles in rat cerebral arteries via activation of MAPK

Cigarette smoke exposure increases the risk of stroke. However, the underlying molecular mechanisms are poorly understood. Endothelin system plays key roles in the pathogenesis of stroke. The present study was designed to examine if lipid-soluble (dimethyl sulfoxide-soluble) cigarette smoke particles (DSP) induces upregulation of contractile endothelin type B (ETB) receptors in rat cerebral arteri

Is nephrolithiasis an unrecognized extra-articular manifestation in ankylosing spondylitis? A prospective population-based Swedish national cohort study with matched general population comparator subjects.

Ankylosing spondylitis (AS) is associated with several extra-articular manifestations. Nephrolithiasis (NL) has not been recognized as one of those, however, several factors known to increase the risk of NL are at play in AS patients. The objective was to estimate rates and predictors of NL in Swedish patients with AS compared to the general population.

Generalisability of clinical registers used for drug safety and comparative effectiveness research: coverage of the Swedish Biologics Register

Objective To determine coverage and generalisability of data in the Swedish Biologics Register ARTIS. Methods Patients with adult onset rheumatoid arthritis (RA) were identified in the National Patient Register and the Swedish Rheumatology Quality Register, including the ARTIS cohort of patients exposed to biological agents. Exposure to etanercept and adalimumab between 2006 and 2008 was determine

Lemming-Food Plant Interactions, Density Effects, and Cyclic Dynamics on the Siberian Tundra

Theory predicts that trophic interactions can produce cyclic dynamics of microtine rodents, but that in addition, social interactions are necessary to create the cyclicity. We tested the induced defence hypothesis as a component driving multiannual cycles by analyzing data on Siberian lemming (Lemmus sibiricus Kerr) populations and the levels of trypsin inhibitors (TI) and free proteins (SPP) in t

Study of the spin and parity of the Higgs boson in diboson decays with the ATLAS detector.

Studies of the spin, parity and tensor couplings of the Higgs boson in the [Formula: see text], [Formula: see text] and [Formula: see text] decay processes at the LHC are presented. The investigations are based on [Formula: see text] of pp collision data collected by the ATLAS experiment at [Formula: see text] TeV and [Formula: see text] TeV. The Standard Model (SM) Higgs boson hypothesis, corresp

Error characterization of the Gaia astrometric solution II. Validating the covariance expansion model

Context. To use the data in the future Gaia catalogue it is important to have accurate estimates of the statistical uncertainties and correlations of the errors in the astrometric data given in the catalogue. Aims. In a previous paper we derived a mathematical model for computing the covariances of the astrometric data based on series expansions and a simplified attitude description. The aim of th

Evolution of “determinants” in sex determination: A novel hypothesis for the origin of environmental contingencies in avian sex bias

Abstract in FinnishSex-determination is commonly categorized as either "genetic" or "environmental"-a classification that obscures the origin of this dichotomy and the evolution of sex-determining factors. The current focus on static outcomes of sex-determination provides little insight into the dynamic developmental processes by which some mechanisms acquire the role of sex determinants. Systems

Kinetic Studies of Amino Acid-Based Surfactant Binding to DNA

In this work, the binding kinetics of amino acid-based surfactants, presenting different linkers and head groups, with calf thymus (CT)-DNA was studied using stopped-flow fluorescence spectroscopy. The kinetic studies were carried out as a function of Na+ concentration and surfactant-to-DNA charge ratio. The surfactant binding on DNA took place in two consecutive steps, for which the corresponding

Varying Virtue : Mythological Paragons of Wifely Virtues in Roman Elegy

This dissertation investigates references to five mythological characters (Penelope, Laodamia, Andromache, Alcestis and Euadne) used as paragons of wifely virtues in Roman elegy. Providing extensive close readings, it discusses the usage of these five characters in the works of Propertius and Tibullus, and in the elegiac works of Ovid, with special reference to issues of narratology, intertextuali
