We propose and theoretically investigate an alternative way to create the poor man's Majorana bound states (MBSs) introduced in Phys. Rev. B 86, 134528 (2012)10.1103/PhysRevB.86.134528. Our proposal is based on two quantum dots (QDs) with strong electron-electron interactions that couple via a central QD with proximity-induced superconductivity. In the presence of spin-orbit coupling and a magneti
A Majorana box - two topological superconducting nanowires coupled via a trivial superconductor - is a building block in devices aiming to demonstrate non-Abelian physics, as well as for topological quantum computer architectures. We theoretically investigate charge transport through a Majorana box and show that current can be blocked when two Majoranas couple to the same lead, fixing their parity
Gambling disorder is an addiction that can cause major suffering, and some populations seem to be more vulnerable than others. Offender populations have a remarkably high prevalence of gambling problems and they are also over-represented in a number of diagnoses related to gambling disorder, like substance use disorders and antisocial personality disorder. Yet, there are few studies investigating
Background: To our knowledge there is no report in the literature on measurements of vertebral rotation with low-dose computed tomography (CT) in prone position.Aims: To describe and test the reliability of this new method, compare it with other methods in use and evaluate the influence of body position on the degree of vertebral rotation measured by different radiological methods.Study design: Re
OBJECTIVE: To ascertain the mortality rate and causes of death in patients with systemic lupus erythematosus (SLE) within a defined region in southern Sweden during the time period 1981-2014 and determine whether these have changed over time. METHODS: In 1981, a prospective observation study of patients with SLE was initiated in southern Sweden. All incident SLE patients within a defined geographi
The advent of nanofocused X-ray beams has allowed the study of single nanocrystals and complete nanoscale devices in a nondestructive manner, using techniques such as scanning transmission X-ray microscopy (STXM), X-ray fluorescence (XRF) and X-ray diffraction (XRD). Further insight into semiconductor devices can be achieved by combining these techniques with simultaneous electrical measurements.
A demonstration of the theoretically predicted non-abelian properties of Majorana bound states (MBSs) would constitute a definite proof of a topological superconducting phase. Alongside the nontrivial braiding statistics, the fusion rules are fundamental properties of all non-abelian anyons. In this work, we propose and theoretically analyze a way to demonstrate MBS fusion rules in a Majorana sing
The prediction, identification, and characterization of phases away from equilibrium conditions remain difficult challenges for material science. Herein, we demonstrate how systems whose phase diagrams contain deeply incising eutectics can offer opportunities to address these challenges. We report the synthesis of a new compound in the Au-Si system, a textbook example of a system with a deep eutec
Background and PurposeIn a previous study comparing the amount of visual field damage at presentation in patients having open-angle glaucoma (OAG) identified through screening and in patients diagnosed in routine clinical practice in the 1990s, the damage was considerably worse in the clinically diagnosed patients. In the present study we compare visual field damage at presentation in the same 402
Background: We aim to estimate population-attributable fractions (PAF) for 13 comorbidities potentially predisposing to hepatobiliary cancer of hepatocellular carcinoma (HCC), gallbladder cancer (GBC), cancers of the intrahepatic and extrahepatic bile ducts (ICC and ECC), and ampullary cancer. Methods: Patients were identified from the Swedish Inpatient Register from 1987 to 2018 and cancers from
Objectives A novel longitudinal clustering technique was applied to comprehensive autoantibody data from a large, well-characterised, multinational inception systemic lupus erythematosus (SLE) cohort to determine profiles predictive of clinical outcomes. Methods Demographic, clinical and serological data from 805 patients with SLE obtained within 15 months of diagnosis and at 3-year and 5-year fol
Research continues to identify genetic variation, environmental exposures, and their mixtures underlying different diseases and conditions. There is a need for screening methods to understand the molecular outcomes of such factors. Here, we investigate a highly efficient and multiplexable, fractional factorial experimental design (FFED) to study six environmental factors (lead, valproic acid, bisp
Background: Temperament and character have been shown to be important factors in understanding psychiatric and neurodevelopmental disorder. Adults with autism spectrum disorder (ASD) have repeatedly been shown to have a distinct temperament and character, but this has not been evaluated in relation to psychiatric comorbidity and ASD diagnostic stability. Aims: To examine temperament and character
OBJECTIVE: To study the effect of methotrexate on male fertility and subsequent effects on their children, for which data are scarce and contradictory.DESIGN: Nationwide multiregister cohort study.SETTING: Not applicable.SUBJECT(S): All children born alive in Sweden between 2006 and 2014 and their fathers. Three cohorts were defined: children to fathers with periconceptional methotrexate exposure
BackgroundUniversity students experience a distinct working environment in the context of completing their studies. In line with existing research into the connection between workplace environment and stress, it is rational to believe that such study environments can affect the level of stress that students experience. However, few instruments have been developed for measuring this.ObjectiveThe ai
Growing evidence suggests that young migrants are particularly vulnerable to sexual violence. As young migrants often lack family and social networks, professionals are often the recipients of disclosures of sexual violence. This study aimed to explore how professionals experience young migrants’ disclosures of sexual violence. A qualitative design was used, based on 14 semi-structured interviews
Background: A diagnosis of prostate cancer (PC) may cause psychosocial distress that worsens quality of life; however, long-term mental health outcomes are unclear. Objective: To determine the long-term risks of major depression and death by suicide in a large population-based cohort. Design, setting, and participants: This was a national cohort study of 180 189 men diagnosed with PC during 1998–2
Background: Global health and sustainable development have increasingly been recognised as important parts of medical education, yet education on these issues remains fragmented and scarce. In 2020, a bill to reform the national medical curricula across all Swedish medical schools was introduced, including a greater emphasis on global health and sustainable development. This study aimed to explore
