Quantum interference in transport through almost symmetric double quantum dots

We theoretically investigate transport signatures of quantum interference in highly symmetric double quantum dots in a parallel geometry and demonstrate that extremely weak symmetry-breaking effects can have a dramatic influence on the current. Our calculations are based on a master equation in which quantum interference enters as nondiagonal elements of the density matrix of the double quantum do

Autonomy and ownership – digital music tools enhance autonomy and musical creativity for children in need of special support : The 22nd annual conference of the Nordic Network for Research in Music Education March 14-16 2017

This presentation highlights results from an action research project in a Swedish primary school. The aim of the project is to investigate digitally-based musical settings with young children in need of special support. Various digital-based music instruments were used to facilitate performing, creating and learning music, alone or in small groups. The theoretical background of the project is foun

Survival in ovarian cancer patients by histology and family history

Introduction. Earlier studies suggest that histology has no prognostic significance in patients with invasive ovarian tumors. Studies about the effect of family history on survival have given conflicting results, which we try to clarify in this study. As an additional question, we examined whether family members share survival experience. Methods. We used the nation-wide Swedish Family-Cancer Data

Effects of neighbourhood and individual factors on injury risk in the entire Swedish population : a 12-month multilevel follow-up study

In this cumulative incidence study of the entire population of Sweden, we examined the association between neighbourhood income level and injury risks across a comprehensive set of individual variables. The population, stratified by age (0-14, 15-64, and > or =65 years), was followed for incident injury events in 1998. Multilevel logistic regression was used to examine the associations between nei

Early-Life Assets in Oldest-Old Age : Evidence From Primary Care Reform in Early Twentieth Century Sweden

Do early-life effects of investments in public health persist to the oldest-old ages? This article answers this question by using the primary care reform in rural Sweden that between 1890 and 1917 led to the establishment of local health districts, together with openings of hospitals and recruitments of medical personnel, as a natural experiment in early-life environmental conditions. The initiati

Continuous-flow LVADs in the Nordic countries : complications and mortality and its predictors

Objectives: The purpose of this study was to assess complications and mortality and its predictors, with continuous-flow left ventricular assist devices (CF-LVADs) in the Nordic Countries. Design: This was a retrospective, international, multicenter cohort study. Results: Between 1993 and 2013, 442 surgically implanted long-term mechanical assist devices were used among 8 centers in the Nordic cou

Potential use of biomass for separation of lignin by hydrotropic extraction

The demand for energy in the world is increasing steadily. As the standard of living for people in the developing countries is increasing so is the net energy use per capita. The main contributor to the energy consumption is the use of fossil fuels, which is also the major emission source for carbon dioxide. Carbon dioxide is in turn one of the most significant greenhouse gases and will enhance te

Malperfusion in acute type A aortic dissection : An update from the Nordic Consortium for Acute Type A Aortic Dissection

Objectives: To evaluate the effect of preoperative malperfusion on 30-day and late mortality and postoperative complications using data from the Nordic Consortium for Acute Type A Aortic Dissection (ATAAD) registry. Methods: We studied 1159 patients who underwent ATAAD surgery between January 2005 and December 2014 at 8 Nordic centers. Multivariable logistic and Cox regression analyses were perfor

Familial Risk for Esophageal Cancer : An Updated Epidemiologic Study From Sweden

Background & Aims: Familial risks for esophageal cancer are not well known, especially for specific histologic types. Methods: We used the nationwide Swedish Family-Cancer Database to examine familial risks for esophageal cancer in offspring. Standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were used to calculate the risk. Age standardized incidence rates for specific hi

Socioeconomic and occupational groups and Parkinson's disease : a nationwide study based on hospitalizations in Sweden

OBJECTIVES: The aim of this study was to investigate whether there is an association between socioeconomic status, occupation and hospitalization for Parkinson's disease (PD).METHODS: A nationwide database was constructed by linking the Swedish Census to the Hospital Discharge Register to obtain data on all first adult hospitalizations for PD diagnosed in Sweden during the study period from 1987 t

Does modularity trump usability? Assessing modular facility solutions for the public sector

Purpose: Western societies are currently facing major demographic changes, due to megatrends such as urbanization, ageing of the population, and migration. These disruptions placea lot of pressure on public services, and consequently on municipal facilities includingschools, day-care centres, and hospitals. The purpose of this study is to examine the potentialof modular facility solutions to respo

Freedom or Love? : Marriage, Single Life, and the Road to Happiness in Swedish 1920s Magazines

This article analyses discourses about self-supporting women in Swedish women’s magazines in the 1920s, after the attainment of legal equality in marriage and the acquisition of the right to vote. The self-supporting middle class woman was a controversial figure in this context. On the one hand symbolizing freedom and independence, she was on the other hand ridiculed and labelled mannish and unatt

Membrane spacers for ultrafiltration: Modelling of mass transfer and pressure

Membrane spacers are an essential part of spiral wound modules and can significantly influence the mass transfer performance and pressure drop in the modules. To develop further understanding of the importance of spacer selection, the performance of two configurations of parallel spacers for ultrafiltration using Dextan T40 was analysed in this study using lab-scale experiments and CFD simulations

Performance of top-quark and W -boson tagging with ATLAS in Run 2 of the LHC

The performance of identification algorithms (“taggers”) for hadronically decaying top quarks and W bosons in pp collisions at s = 13 TeV recorded by the ATLAS experiment at the Large Hadron Collider is presented. A set of techniques based on jet shape observables are studied to determine a set of optimal cut-based taggers for use in physics analyses. The studies are extended to assess the utility

A Bayesian method to localize lost gamma sources

A feasibility study of a Bayesian based algorithm for orphan source localization by means of mobile gamma spectrometry is presented. The method was tested on three types of gamma sources (137Cs, 133Ba and 131I) using a HPGe detector mounted on a vehicle. Estimates on source activity and source locations were within 51% and 29% of actual values, respectively. Further studies are required to validat

Systematics for types and effects of DNA variations

Background: Numerous different types of variations can occur in DNA and have diverse effects and consequences. The Variation Ontology (VariO) was developed for systematic descriptions of variations and their effects at DNA, RNA and protein levels. Results: VariO use and terms for DNA variations are described in depth. VariO provides systematic names for variation types and detailed descriptions fo
