We show how a careful analysis of the behaviour of a parton shower Monte Carlo in the vicinity of the soft and collinear regions allows one to formulate a modified MC@NLO-matching prescription that reduces the number of negative-weight events with respect to that stemming from the standard MC@NLO procedure. As a first practical application of such a prescription, that we dub MC@NLO-∆, we have impl

Multi-peaked spectra of the primordial gravitational waves are considered as a phenomenologically relevant source of information about the dynamics of sequential phase transitions in the early Universe. In particular, such signatures trace back to specific patterns of the first-order electroweak phase transition in the early Universe occurring in multiple steps. Such phenomena appear to be rather

På uppdrag av Riksförbundet FUB har en granskning genomförts av tolkning och tillämpning av begreppet ”normalt föräldraansvar” och vad detta innebär i relation till olika stöd- och serviceinsatser enligt lagen om stöd och service till vissa funktionshindrade (LSS). Vidare har Försäkringskassans tolkning och tillämpning av begreppet utifrån ersättningar som ges via Socialförsäkringsbalken (SFB) und

Study Design: Prospective register cohort study. Objectives: The indication for surgery in patients with lumbar spinal stenosis (LSS) is considered to be leg pain and neurogenic claudication (NC). Nevertheless, a significant part of patients operated for LSS have mild leg pain levels defined as leg pain ≤minimally important clinical difference (MICD). Information is lacking on how to inform these

Introduction: Magnetic resonance imaging (MRI) is an important modality in diagnostics and treatment follow-up. However, MRI can be perceived as unpleasant even though the examination is non-invasive. Patients' knowledge of the MRI procedure is usually scarce, which may enhance patient anxiety at examination. We investigated the effects on anxiety and satisfaction with an information booklet on MR

Evidence for potential effects of inorganic nitrate (NO3) on body weight is limited to inconsistent findings of animal experiments. In this systematic review and meta-analysis, we aimed to quantify the overall effect of inorganic NO3, administered via drinking water, on body weight gain in rats. We searched PubMed, Scopus, and Embase databases, and the reference lists of published papers. Experime

Erythropoiesis is intimately coupled to cell division, and deletion of the cell cycle regulator retinoblastoma protein (pRb) causes anemia in mice. Erythroid-specific deletion of pRb has been found to result in inefficient erythropoiesis because of deregulated coordination of cell cycle exit and mitochondrial biogenesis. However, the pathophysiology remains to be fully described, and further chara

This review discusses magnetomotive ultrasound, which is an emerging technique that uses superparamagnetic iron oxide nanoparticles as a contrast agent. The key advantage of using nanoparticle-based contrast agents is their ability to reach extravascular targets, whereas commercial contrast agents for ultrasound comprise microbubbles confined to the blood stream. This also extends possibilities fo

In this experimental study, mass transfer and hydrodynamic parameters of water/kerosene/acetic acid system in a packed column were investigated, in which the mass transfer direction was set from the continuous phase (saturated water of kerosene and acetic acid) to the dispersed phase (saturated kerosene of water) in all the experiments. To assess the impact of nanoparticles on mass transfer, the e

Background: A common bearing combination in total hip arthroplasty today is a metal femoral head articulating with polyethylene in the cup. Ceramic heads are thought to be more resistant to third-body damage, and have better wettability and decreased surface roughness, which taken together have been suggested to result in less polyethylene wear. The purpose of this study is to compare the initial

Investment in railways, and transport infrastructure in general, are often motivated because they are believed to improve peoples’ accessibility to jobs. By linking together and increasing the size of labour markets, the matching between individuals and jobs is improved, and the productivity increases. Communities and municipalities lobby for investments that lead to higher accessibility and those

Background: Recent reports suggest that the negative association between diabetes mellitus and abdominal aortic aneurysm (AAA) may be driven by metformin, the world's most common antidiabetic drug rather than diabetes per se. We sought to investigate the association among AAA growth rate, chemokine profile, and metformin prescription in a contemporary Swedish cohort. Methods: Patients under survei
