The Radon transform and its adjoint, the back-projection operator, can both be expressed as convolutions in log-polar coordinates. Hence, fast algorithms for the application of these operators can be constructed by using FFT, if data is resampled at log-polar coordinates. Radon data is typically measured on an equally spaced grid in polar coordinates, and reconstructions are represented (as images

Objectives Whether the increased risk of comorbidities, such as cardiovascular disease, in rheumatoid arthritis (RA) can be reverted by particular antirheumatic therapies, or response to these, is unclear but of critical clinical importance. We wanted to investigate whether response to tumour necrosis factor inhibitors (TNFi) translates into a reduced risk for acute coronary syndrome (ACS). Method

Peak bone mass is normally reached in the third decade of life. Previously, in the population-based PEAK-25 cohort (n = 1061, age 25.5 ± 0.2), we demonstrated that bone mineral density in the population-based PEAK-25 cohort is comparatively high; therefore, this study aimed to determine if the calcaneus microarchitecture mirrored this. In the process, we describe normative quantitative ultrasound

The present contribution presents event-related potential (ERP) and functional magnetic resonance imaging (fMRI) findings related to the processing of Swedish word accents. These results are then discussed and further analysed in the context of models of word activations and phonological neighbourhoods. It has previously been seen that word accents (either a low tone (accent 1) or a high tone (acc

This paper reviews the growing literature on “state capacity” in political science and related disciplines and proposes a new conceptualization of state capacity. The paper argues that most existing definitions and theories of state capacity are too closely tailored to explaining a particular set of outcomes – such as economic growth – which limits the applicability of the concept of state capacit

Relying on three new indicators of the information capacity of states, this paper provides new evidence on the ability of states to collect and process information about the territories and populations that they govern. The three indicators are (a) the availability of a reliable census, (b) the establishment of a permanent government agency tasked with processing statistical information about the

Recently several distinct literatures have thematically converged around the topic of non-European state-making: political scientists – both comparativists and international relations scholars, historical sociologists, comparative and world historians, anthropologists, archaeologists and others, have begun to interest themselves in state making or state formation in non-European settings, and also

Since the German reform of asylum law in 1993, statistics indicate a significant decrease of protection claims and an increasing number of deportations. This article presents relevant domestic legislation and international agreements contributing to this development It focuses on how domestic and international law interact to inhibit or end the presence of protection seekers on German territory. I

Having left their home country, 18 million refugees and other protection seekers cannot exert their rights to democratic participation. As a consequence, they are deprived of all influence on a legal instrument of existential importance for them, namely the grant of asylum. Can the exclusion of refugees from the framing of aliens legislation be justified?The analysis carried out in this text proce

This text aims at exploring the relationship between a more equitable sharing of the responsibility for protection seekers and the normative framework on refugees and immigration already existing in Europe.

The revised version of the Swedish Aliens Act contains a specific category providing protection for persons who fear persecution on account of their sex. Benefits afforded under this category, however, fall short of those under the 1951 Convention relating to the Status of Refugees or article 3 of the European Convention for the Protection of Human Rights and Fundamental Freedoms. In order to eval

Are foreign ministers punished for their performance in office, or when the country loses a war? The literature has increasingly recognized the importance of individual leaders when explaining foreign policy outcomes. Several scholars have focused on the survival of leaders as an important predictor of war onset, which has created an interest in predicting the survival of heads of governments. We
