This article presents a study of the variation found in the oral production of verbs in L2 French by adult beginners with Swedish as L1. The study deals with the production of the two main forms of regular verbs in spoken French, a short form /parl/ and a long form /parle/, in present-tense and infinitive contexts. Learners at beginner stages use these two forms invariantly in both finite and non-
In therapy imaging there is a need to optimize imaging protocols and different correction methods for e.g. photon attenuation, contribution from scatter and other physics-related effects that limits the possibility to achieve accurate quantitative results. Physical phantom studies are important but lack flexibility and are often difficult to make patient realistic. A complement is to simulate the
BackgroundObesity is a complex disease caused by the interplay of genetic and lifestyle factors, but identification of gene-lifestyle interactions in obesity has remained challenging. Few large-scale studies have reported use of genome-wide approaches to investigate gene-lifestyle interactions in obesity.MethodsIn the PROMIS study, a cross-sectional study based in Pakistan, we calculated BMI varia
The association of contemporary hosts and their parasites might reflect either cospeciation or more recent shifts among existing hosts. Cospeciation implies that lineages of hosts and parasites diverge in parallel at the same time, but testing this prediction requires time-calibrated phylogenies, which are particularly difficult to obtain in organisms that leave few fossils. It has successively be
When isolated conjugated polymer (CP) chains are studied by single molecule spectroscopy, excitation power density in the range of 10-1000 W cm(-2) is normally used. We show that at such excitation power densities the fluorescence ability of CPs is significantly reduced. A new methodological approach allowed us to measure the fluorescence quantum yield (QY) of thin matrix polymer films doped with
Recent genome-wide meta-analyses identified 157 loci associated with cross-sectional lipid traits. Here we tested whether these loci associate (singly and in trait-specific genetic risk scores [GRS]) with longitudinal changes in total cholesterol (TC) and triglyceride (TG) levels in a population-based prospective cohort from Northern Sweden (the GLACIER Study). We sought replication in a southern
The cross-section average (CA) augmentation approach of Pesaran (A simple panel unit root test in presence of cross-section dependence. Journal of Applied Econometrics 2007; 22: 265–312) and Pesaran et al. (Panel unit root test in the presence of a multifactor error structure. Journal of Econometrics 2013; 175: 94–115), and the principal components-based panel analysis of non-stationarity in idios
P>The efficacy and safety of zanolimumab (HuMax-CD4) in patients with relapsed or refractory peripheral T Cell lymphoma (PTCL) was evaluated. Twenty-one adult patients with relapsed or refractory CD4+ PTCL of non-cutaneous type (angioimmunoblastic T cell lymphoma (AITL) n = 9, PTCL-not otherwise specified (NOS) n = 7, anaplastic large cell lymphoma (ALCL) n = 4 and enteropathy type T cell lymphoma
The aim of this study was to examine the expression of serotonin receptors in patients with breast cancer and to explore their utility as diagnostic and prognostic markers. Immunohistochemical analysis was performed to examine the expression of serotonin (5-HT) receptor subtypes 1A, 1B, 2B and 4 in a tissue microarray containing tumor specimens from 102 patients. Statistical analysis was performed
We investigate the temperature dependence of the O-H stretch band in the infrared absorbance spectra of the proton-conducting hydrated perovskites BaInxZr1-xO3-x/2 (x = 0.10-0.75) over the temperature range -160 to 350 degrees C. Upon increasing temperature from -160 to 30 degrees C, we show that there is a redistribution of protons from nonsymmetrical structural configurations, such as Zr-OH-In a
Objective: To evaluate whether the duration of the active phase of labor is associated with maternal body mass index (BMI), in nulliparous women with spontaneous onset of labor. Study design: Historical prospective cohort study including 63,829 nulliparous women with a singleton pregnancy and a spontaneous onset of labor, who delivered between January 1, 1995 and December 31, 2009. Data were colle
The aim of this study was to employ an experimental protocol for in vivo evaluation of sols of 5 wt.\% poly(ethylene glycol) (PEG) in phosphate buffered saline (PBS) as artificial vitreous substitutes. A 20 gauge pars plana vitrectomy and posterior vitreous detachment were performed in the right eye of 8 pigmented rabbits. Approximately 1 mL of the viscoelastic PEG sols were then injected into the
Molecular mechanics with generalised Born and surface area solvation (MM/GBSA) is a popular method to calculate the free energy of the binding of ligands to proteins. It involves molecular dynamics (MD) simulations with an explicit solvent of the protein-ligand complex to give a set of snapshots for which energies are calculated with an implicit solvent. This change in the solvation method (explic
We present a structural analysis of halo star clusters in M31 based on deep Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) imaging. The clusters in our sample span a range in galactocentric projected distance from 13 to 100 kpc and thus reside in rather remote environments. Ten of the clusters are classical globulars, whilst four are from the Huxor et al. population of extended, ol
Eye gaze is a window onto cognitive processing in tasks such as spatial memory, linguistic processing, and decision making. We present evidence that information derived from eye gaze can be used to change the course of individuals’ decisions, even when they are reasoning about high-level, moral issues. Previous studies have shown that when an experimenter actively controls what an individual sees
Vulcanization of rubber changes its allergen pattern.
Giant and colossal deep-sea squid (Architeuthis and Mesonychoteuthis) have the largest eyes in the animal kingdom [1, 2], but there is no explanation for why they would need eyes that are nearly three times the diameter of those of any other extant animal. Here we develop a theory for visual detection in pelagic habitats, which predicts that such giant eyes are unlikely to evolve for detecting mat
