In multiple-planet systems, gravitational interactions of exoplanets could lead to transit timing variations (TTVs), whose amplitude becomes significantly enhanced when planets are in or near mean-motion resonances (MMRs), making them more easily detectable. In cases where both TTVs and radial velocity (RV) measurements are available, combined analysis can break degeneracies and provide robust pla

Objective: Abdominal aortic graft and endograft infection (AGI) is primarily treated by resection of the infected graft and restoration of distal perfusion through extra-anatomic bypass (EAB) or in situ reconstruction/repair (ISR). The aim of this study was to compare these surgical strategies in a nationwide multicentre retrospective cohort study. Methods: The Swedish Vascular Registry (Swedvasc)

Tools for accurate measurements of microbial biomass/abundance are imperative in soil ecology. This perspective was prompted by a lack of consistency in how the neutral lipid fatty acid (NLFA) and phospholipid fatty acid (PLFA) 16:1ω5 are used to estimate arbuscular mycorrhizal (AM) fungal abundance, which we argue can lead to erroneous conclusions within studies and complicate among-study compari

The variety of different controllers is today very big. Much research is done in the field of neural network control and more well established technologies are sometimes looked at as old fashioned. The work is much based on the identification of a process model. In this report some different controllers have been built to see if neural networks are a good alternative to classic controllers. The cl

The purpose of this thesis is to investigate and analyze power relations between Muslim female and male employees, active in working together with gender issues in two Indonesian non governmental organizations in Java. The study analyzes power relations and gendered work among female and male employees in the daily work and aims to give a picture on both female and male experiences from working to

Virtual reality headsets, such as the HTC Vive, can be used to model objects, forces, and interactions between objects with high perceived realism and accuracy. Moreover, they can accurately track movements of the head and the hands. This combination makes it possible to provide subjects with precise quantitative feedback on their performance while they are learning a motor task. Juggling is a cha

Novelty is a core value in science, and a reliable measurement of novelty is crucial. This study proposes a new approach of measuring the novelty of scientific articles based on both citation data and text data. The proposed approach considers an article to be novel if it cites a combination of semantically distant references. To this end, we first assign a word embedding–a vector representation o

Purpose: To assess the change in mammography screening attendance in Sweden—overall and in sociodemographic groups at risk of low attendance—after removal of the out-of-pocket fee in 2016. Methods: Individual-level data on all screening invitations and attendance between 2014 and 2018 were linked to sociodemographic data from Statistics Sweden. Odds ratios and 95% confidence intervals (CIs) for at

This thesis explores the emerging strategy of nation sub-branding and critically argues for the domestic implications it has on national identities and the falsely promoted tradition of social justice. The study situates itself within the critical cultural stream of nation branding research, rejecting, however, prior scholarly presumption that a segmented nation brand could mean less marginalizati

This research is dedicated to a problem of discrimination of women in local politics in Ukraine. It explores what are the forms of discrimination that women engaged in local politics face, how they perceive and handle discrimination and what kind of impact it has on their political careers. This thesis employs socio-psychological theories of discrimination, the ambivalent sexism theory and the con

At the foundation of most inequalities in expression of sexuality lie the social constructions of gender. For this reason I consider sex and sexuality education as a possibility to challenge institutionalised sexism and enhance sexual well-being. As sex education has become a battle of morality, non-governmental organisations and others can be seen as alternatives to the national curriculum plan e

Sverige är en representativ demokrati, vilket innebär att vi väljer de personer vi vill ska styra samt har möjlighet att uttrycka våra åsikter tack vare yttrandefriheten. Ändå finns det dem som väljer att handla på ett brottsligt sätt för att påvisa fel eller orättvisor i samhället. I En uthållig demokrati anses att rätten bör ta hänsyn till personens moraliska motiv i mål som handlar om civil oly

Våldtäkter i Sverige är ett fenomen som fått mycket belysning i media, men där det funnits ganska lite forskning om hur profilerna på de som begår brotten ser ut. Gärningsmannaprofilering har ett värde i att det kan hjälpa polisen avgränsa sökområdet, men profilering är också en disciplin inom forskningen där det funnits stora skillnader mellan olika länder. Därför är det viktigt att det bedrivs fRape is a criminal phenomenon that is widely recognized in Sweden, both journalistically and politically, but where research concerning the offenders' profiles is very sparse. Offender profiling is a valuable investigative tool which may help law enforcement limit their search parameters and prevent information overload. However, there are national disparities between crime scene actions and b

Abstract The study of teachers and students’ perceptions of second language acquisition (SLA) and teaching began in earnest with Horwitz’s seminal research during the 1980s. Numerous studies into both teachers and learners’ belief systems have since then been conducted by researchers and educators (Bell, 2005; Borg & Burns, 2008; Brown, 2009; Davis, 2003; Horwitz, 1987, 1988; Lasagabaster &

Children and adolescents exposed to traumatic events are at high risk of developing posttraumatic stress disorder (PTSD). With the rare exception of very young children, their PTSD presentations at the symptom level are similar to those of trauma-exposed adults, as are their patterns of psychiatric comorbidity, particularly for adolescents. Untreated, at least a significant proportion will carry o

Background. Many individuals are infected with the bacterium Helicobacter pylori. Some develop ulcers or mucosal atrophy. Aims. To correlate the histological characteristics of the H. pylori-induced gastritis to the immunoblot pattern of the H. pylori infection and to compare the presence of H. pylori bacteria in tissue specimens with ELISA serology and immunoblot analysis. Methods. One hundred an

The “acidic mantle” of the skin surface has been related to several essential functions of the skin, although the origin of the acidity is still obscure. In this paper, we investigate how different transport processes can influence the local proton concentration inside a membrane consisting of oriented lipid bilayers. This system is chosen as a simple model of the extracellular lipids in the upper

The global surgery workforce is in crisis in many low- and middle-income countries (LMICs). The shortage of surgery, obstetrics, and anesthesia providers is an important cause of the unmet need for surgical care in LMICs. The goal of this paper is to summarize the available literature about surgical physicians in LMICs and to describe ongoing initiatives to supplement the existing surgical workfor
