In many ferroelectrics, large electromechanical strains are observed near regions of composition- or temperature- driven phase coexistence. Phenomenologically, this is attributed to easy re-orientation of the polarization vector and/or phase transition, although their effects are highly convoluted and difficult to distinguish experimentally. Here, we used synchrotron X-ray scattering and digital i
The real-world impact of psychosis prevention is reliant on effective strategies for identifying individuals at risk. A transdiagnostic, individualized, clinically-based risk calculator to improve this has been developed and externally validated twice in two different UK healthcare trusts with convincing results. The prognostic performance of this risk calculator outside the UK is unknown. All ind
Background: Acute coronary syndromes most commonly arise from thrombosis of lipid-rich coronary atheromas that have large plaque burden despite angiographically appearing mild. Objectives: This study sought to examine the outcomes of percutaneous coronary intervention (PCI) of non–flow-limiting vulnerable plaques. Methods: Three-vessel imaging was performed with a combination intravascular ultraso
Previous research has shown that polygenic risk scores (PRSs) can be used to stratify women according to their risk of developing primary invasive breast cancer. This study aimed to evaluate the association between a recently validated PRS of 313 germline variants (PRS313) and contralateral breast cancer (CBC) risk. We included 56,068 women of European ancestry diagnosed with first invasive breast
The mechanisms by which lime and/or phosphate addition impacts the preservation of soil organic matter (OM) are poorly understood. We explored the changes in quantity and chemistry of water-extractable organic matter (WEOM) in the bulk soil and its heavy density fraction (>1.6 g/cm3) of an unmanaged C-rich volcanic soil caused by lime and/or phosphate application. The addition of lime or phosphate
BACKGROUND: The comparative efficacy and safety of ticagrelor versus clopidogrel in older patients with myocardial infarction (MI) has received limited study. METHODS: We performed an observational analysis of all patients ≥80 years (n=14 005) who were discharged alive with aspirin combined with either clopidogrel (60.2%) or ticagrelor (39.8%) after a MI between 2010 and 2017 registered in the nat
Neuroblastoma is a childhood tumor of the sympathetic nervous system and the most common tumor form diagnosed in infants. Patients with aggressive tumors are treated intensely with multi-modal therapy including chemotherapy, surgery, radiotherapy and immunotherapy. Despite this, many children suffer from incurable relapses and long-term side effects are common. Novel treatments are thus necessary
Madsen et al. show substantial long term (26 years) population demography and genetic benefits of genetic rescue of an initially inbred adder (Vipera berus) population. A post-rescue genetic bottleneck did not affect population genetic diversity. To be successful large numbers of novel alleles should be introduced into the focal population.
Recent genome-wide association studies (GWAS) identified DUSP8, encoding a dual-specificity phosphatase targeting mitogen-activated protein kinases, as a type 2 diabetes (T2D) risk gene. Here, we reveal that Dusp8 is a gatekeeper in the hypothalamic control of glucose homeostasis in mice and humans. Male, but not female, Dusp8 loss-of-function mice, either with global or corticotropin-releasing ho
Mot bakgrund av den nuvarande och framtida kompetensbrist som kännetecknar offentlig sektor, syftar föreliggande studie till att bidra till såväl forskning som praktik genom sitt fokusera på talangförsörjning. Studien har koncentrerats dels kring två frågor: 1. Hur använder sig ett antal av Skånes offentliga organisationer av HR-driven talent management för sin talangförsörjning? 2. Hur an
We take a fresh look at Feynman diagrams in the spinor-helicity formalism. Focusing on tree-level massless QED and QCD, we develop a new and conceptually simple graphical method for their calculation. In this pictorial method, which we dub the chirality-flow formalism, Feynman diagrams are directly represented in terms of chirality-flow lines corresponding to spinor inner products, without the nee
Baserat på ett empiriskt material som består av enkätsvar och intervjuer samt kompletterande dokumentgranskning från landets samtliga 21 landsting och regioner(endast dokumentgranskning i två fall) tar sig den här rapporten an två syften: Att ge en heltäckande bild av de modeller för styrning, inklusive ersättningsmodeller,som tillämpas i svensk primärvård samt en analy
Det övergripande syftet i denna studie är attjämföra och analysera skillnader och likheter mellan att leda i kommunal och icke-kommunal regi för rektorer i gymnasieskolan och enhetschefer för äldreboenden. Ambitionen ärockså att beskriva hur kraven fördessa två chefskategorier har förändratssedanbörjan av 1990-talet samt vad i omvärlden som för närvarande påverkar deras
The aethalometer model has shown to offer a fast, inexpensive and robust method for source apportionment. The method relies on aerosol light absorption attribution, mass balance of the total carbon and results in a fraction of unaccounted, residual carbon that has been associated to biogenic carbon due to its presumably non-light absorbing properties. This residual carbon and its relation to trace
