Objective. To describe the change of pain reports over time in 3 cohorts derived from the general population: (1) no chronic pain (NCP, n = 1156); (2) chronic regional pain (CRP n = 502) and (3) chronic widespread pain (CWP; n = 242). To identify risk factors that predict the development or persistence of chronic widespread pain. Methods. A 3-year followup from 1995 to 1998 with postal questionnai
A fully integrated instrument for cereal grain quality assessment is presented. Color video images of grains fed onto a belt are digitized. These images are then segmented into kernel entities, which are subject to the analysis. The number of degrees of freedom for each such object is decreased to a suitable level for Artificial Neural Network (ANN) processing. Feed- forward ANN's with one hidden
Patent citations added by examiners are often used as indicators of technological impact and knowledge flows, despite various criticisms. In this study we analyze the distribution of examiner patent citations according to patent characteristics in order to show their limitations. According to our findings, the number of applicant citations included is dependent on the science-base of the technolog
Bouncing on a trampoline lets the jumper experience the interplay between weightlessness and large forces on the body, as the motion changes between free fall and large acceleration in contact with the trampoline bed. In this work, several groups of students were asked to draw graphs of elevation, velocity and acceleration as a function of time, for two full jumps of the 2012 Olympic gold medal tr
Popular Abstract in Swedish Prosodi och intonation är viktiga delar i det mänskliga talet. I system för text-till-talomvandling och automatisk taligenkänning måste prosodiska modeller inkluderas för att uppnå acceptabla resultat. Denna avhandling bidrar till modelleringen av svensk prosodi ur lexikalt och akustiskt perspektiv. Tre aspekter av lexikal modellering av prosodi studeras. Vi skisserar Prosody and intonation are very important ingredients of human speech. In speech technology, text-to-speech (TTS) and automatic speech recognition (ASR) systems must incorporate prosodic models in order to reach acceptable performances. We contribute to the modelling of Swedish prosody in a speech technology context from lexical and acoustic angles. Three aspects of lexical prosodic modelling are
In this paper, we analyze the potentials of a four-phase 14-GHz CMOS voltage-controlled oscillator, tailored to a sub-harmonic receiver, for signal processing at Ka-band. When mild phase accuracies between in-phase and quadrature down-converted signals are required, the four-phase oscillator displays roughly the same phase noise figure-of-merit as quadrature oscillator counterparts. However, the o
According to religious fictionalism, a non-believer can participate in religious life by playing a game of make-believe. Considering how games of make-believe build on imagination and pretence, I argue that religious fictionalism requires the non-believing participant to engage in role-playing. Turning to the literature on role-playing games, I demonstrate how religious fictionalism conforms to a
Startups use prototyping to develop and validate their products and business models. For startups, it is important to have a good knowledge of relevant adoption factors, to make decisions regarding which prototyping technology to adopt. In this article, we identify such factors based on our practical experiences of startups in various industries. We define a research framework, describe challenges
The economics of biobanking are intertwined with its social and scientific aspects. In this article, we illustrate this interrelationship and describe two problems that structure the discussion about the economics of biobanking. First, there is a “sustainability problem” about how to maintain biobanks in the long term. Second, and representing a partial response to the first problem, there is a “c
Soil contamination is a widespread problem and action needs to be taken in order to prevent damage to the groundwater and the life around the contaminated sites. In Sweden, it is estimated that more than 80,000 sites are potentially contaminated, and therefore, there is a demand for investigations and further treatment of the soil. In this paper, we present the results from a methodology applied i
In memorium commentary about the Romanian anthropologist Vintila Mihailescu, who died in 2020, published as part of several contributions in Anuac, the journal of the Italian Society for Cultural Anthropology
Imprinted genes, giving rise to parent-of-origin effects (POEs), have been hypothesised to affect type 1 diabetes (T1D) and rheumatoid arthritis (RA). However, maternal effects may also play a role. By using a mixed model that is able to simultaneously consider all kinds of POEs, the importance of POEs for the development of T1D and RA was investigated in a variance components analysis. The analys
The paper explores the flux of male homosexual identity between urban subcultures and small rural settings in Sweden. Eve Kosofsky Sedgwick has claimed that we cannot interpret Foucault’s History of Sexuality as if one understanding of sexuality was substituted by another, but that many forms of sexuality coexist in any given time. Inspired by her analysis, this paper claims that a shift between t
Experiments have shown that the time is now ripe for a new generation of interactive learning tools for control. The tools are based on objects which admit direct graphical manipulation. During manipulations, objects are updated instantaneously, so that relations between objects are maintained all the time. The tools are natural complements to traditional education, and allow students to quickly g
