Ultra-hypofractionated versus conventionally fractionated radiotherapy for prostate cancer : 5-year outcomes of the HYPO-RT-PC randomised, non-inferiority, phase 3 trial

Background: Hypofractionated radiotherapy for prostate cancer has gained increased attention due to its proposed high radiation-fraction sensitivity. Recent reports from studies comparing moderately hypofractionated and conventionally fractionated radiotherapy support the clinical use of moderate hypofractionation. To date, there are no published randomised studies on ultra-hypofractionated radiot

Simulation and Estimation of Diffusion Processes : Applications in Finance

Kvantitativ analys är en teknik som syftar till att förstå komplexa system genom att använda matematisk och statistisk modellering. Det är en viktig del av dagens finansiella system och innebär bland annat att modellera den slumpmässiga utvecklingen av finansiella tillgångar, och för att förutspå verkliga händelser som till exempel förändring av riksbankens styrränta. En mycket vanlig metod som anDiffusion processes are the most commonly used models in mathematical finance, and are used extensively not only by academics but also practitioners. Nowadays a wide range of models, that can capture many of the effects observed in financial markets, are available. A very important task is to calibrate the models to observed market data and to achieve a good fit, since a slight misspecification ca

Probing Stark-induced nonlinear phase variation with opto-optical modulation

We extend the recently developed technique of opto-optical modulation (OOM) to probe state-resolved ac-Stark-induced phase variations of a coherently excited ensemble of helium atoms. In a joint experimental and theoretical study, we find that the spatial redirection of the resonant emission from the OOM process is different for the low-lying 1s2p state as compared with the higher-lying Rydberg st

First-principles characterization of Mg low-index surfaces : Structure, reconstructions, and surface core-level shifts

In this paper, first-principles calculations provide structural characterization of three low-index Mg surfaces - Mg(0001), Mg(1010), and Mg(1120) - and their respective surface core-level shifts (SCLSs). Inspired by the close similarities between Be and Mg surfaces, we also explore the reconstruction of Mg(1120). Through the calculation of surface energies and the use of the angular-component dec

Circulating HER2/ErbB2 Levels Are Associated With Increased Incidence of Diabetes : A Population-Based Cohort Study

OBJECTIVE: HER2/ErbB2 is a member of the epidermal growth factor receptor family. It is widely used as a tumor marker, but it also has recently been associated with insulin resistance. Both ErbB2 and diabetes have been associated with cancer; however, the relationship between ErbB2 and diabetes has not been well explored. The aim of this population-based cohort study was to assess the association

Design guidelines for fluid-elastic instability of tube bundles subjected to two-phase cross flow

Fluid-elastic instability of tube bundles is the main cause of vibration failure of heat exchangers. To establish more reasonable and reliable design guidelines for fluid-elastic instability of tube bundles subjected to two-phase cross flow, we investigated experimentally the effects of the flow conditions of the two-phase flow and the geometrical characteristics of the tube bundles on damping, vi

Molecular determinants of disease severity in urinary tract infection

In the urinary tract, Escherichia coli infection may result in life-threatening disease, or asymptomatic bacterial carriage, comparable to bacterial commensalism in the gut. Pathogenic strains trigger a disease provoking host response which differs depending on the infected organ. The diversity of the response reflects the virulence repertoire of the infecting strain and by the susceptibility of t

Struggles over Human Smuggling in Court: Challenging National and European Border Regimes

In this paper, we explore the ways in which national and European border regimes have been chal- lenged by cases of “compassionate smuggling” of refugees. We centre the analysis around a Swedish case, in which three film makers accompanied a boy from Syria on his journey through Europe in 2015, while at the same time documenting the journey in a documentary film. After the screening of the film inIn this paper, we explore the ways in which national and European border regimes have been challenged by cases of “compassionate smuggling” of refugees.

Emerging local solidarities? Local responses to migration to non-urban communities in the south of Sweden

In a time of harshening border control and public discourses on securitisation and “crisis” at the national as well as European levels, it is of interest to explore local responses to migration, especially in areas outside of the larger cities. Local organising in support of different migrant groups, as well as more hostile or openly racist responses, are not new phenomena. However, we argue that

Multi-particle momentum correlations extracted using covariance methods on multiple-ionization of diiodomethane molecules by soft-X-ray free-electron laser pulses

Momenta of ions from diiodomethane molecules after multiple ionization by soft-X-ray free-electron-laser pulses are measured. Correlations between the ion momenta are extracted by covariance methods formulated for the use in multiparticle momentum-resolved ion time-of-flight spectroscopy. Femtosecond dynamics of the dissociating multiply charged diiodomethane cations is discussed and interpreted b

Attitudinal and Motivational Profiles of Second Foreign Language Learners in Multilingual Contexts

Abstract: Reports and studies repeatedly indicate that foreign languages other than English are facing major challenges in European educational systems (European Commission, 2012). In Sweden, pupils’ motivation to learn a second foreign language (SFL) is reported to be low while motivation to learn English is high (Eurobarometer 2012, Tholin & Lindqvist 2009).
