A large amount of scientific work has been carried out to enhance the methods used for design and control of technical systems. For many of these systems, the main objective is to utilize the limited resources in an optimal way. Different simulation techniques have, in many cases, been successfully applied to the analysis. When working with technical systems, it is important to have a common notat
Objective In patients with traumatic knee distorsion and hemarthrosis, to investigate the panorama of structural injury, as visualized on magnetic resonance imaging (MRI). Design Cohort study of 1145 consecutive patients with traumatic knee distorsion who underwent MRI within median 8 days after injury. We present structural injury as visualized on MRI in relation to age, sex and activity at injur
We tested domestic cats in the cylinder task, and found that they perform better ifthe cylinder is larger. We also found that their highest performance parallels that ofgreat apes and corvids, which are known as the best performing animals on this task.The cylinder task is used to test animals’ motor self-regulation. Recently a large-scalestudy tested 36 species on the task and found that absolute
We consider the potential for positioning with a system where antenna arrays are deployed as a large intelligent surface (LIS), which is a newly proposed concept beyond massive multi-input multi-output (MIMO) where future man-made structures are electronically active with integrated electronics and wireless communication making the entire environment "intelligent". In a first step, we derive Fishe
Objective: Experimental findings and previous observational data have suggested lower risk of osteoarthritis (OA) with statin use but results are inconsistent. Large-scale studies with a clinically important outcome are needed. Thus, we aimed to determine whether statin use is associated with a reduced risk of developing clinically-defined hip or knee OA. Design: Pooled analysis based on time-to-e
Objectives: To examine the association between race and pre-eclampsia and gestational hypertension after adjustment for factors in maternal characteristics and medical history in a screening study from the Fetal Medicine Foundation (FMF) in England, and to perform a systematic review and meta-analysis of studies on pre-eclampsia. Design: Prospective observational study and systematic review with m
That Florida is in the midst of an ecological crisis is a perspective increasingly shared by academy, government, private industry and civil society. Ideas about the causes of the state’s environmental problems and how best to address them, however, are not so well aligned. While some are prone to emphasize the primacy of economic growth over environmental conservation, others argue that, like lov

Drawing on social stratification and relative resource theory, and gender ideology theory, this article investigates how class and gender shape outsourcing domestic work patterns within the Swedish welfare state, a forerunner in terms of gender equality. Using full-population longitudinal administrative registers from 2007 to 2022, we include individual-level information on domestic outsourcing fo
Most current models of recognition memory fail to separately model item and person heterogeneity which makes it difficult to assess ability at the latent construct level and prevents the administration of adaptive tests. Here we propose to employ a General Condorcet Model for Recognition (GCMR) in order to estimate ability, response bias and item difficulty in dichotomous recognition memory tasks.
Background: Magnetic resonance (MR) safety procedures are designed to allow patients, research subjects and personnel to enter the MR-scanner room under controlled conditions and without the risk to be harmed during the examination. Ferromagnetic objects in the MR-environment or inside the human body represent the main safety risks potentially leading to human injuries. Screening for MR-safety ris
Diversifying cropping systems by increasing the number of cash and cover crops in crop rotation plays an important role in improving resource use efficiency and in promoting synergy between ecosystem processes. The objective of this study was to understand how the combination of crop diversification practices influences the performance of arable crop sequences in terms of crop grain yield, crop an
Aims: The association between cancer and survival after out-of-hospital cardiac arrest (OHCA) has not been thoroughly investigated. We aimed to address this knowledge gap using national, population-based registries. Methods and results: For this study, 30 163 patients with OHCA (≥18 years) were included from the Swedish Register of Cardiopulmonary Resuscitation. Through linkage to the National Pat
Det övergripande syftet med denna licentiatavhandling är att öka kunskapen kring vad som påverkar att jobba som en brandman vars huvudsakliga sysselsättning är utanför räddningstjänsten (exempelvis frivilliga brandmän eller deltidsbrandmän) för att förstå hur utmaningar och engagemang påverkar beslutet att fortsätta vara verksam. Bibehållandet av dessa brandmän är en välkänd utmaning i många ländeThe overarching aim of this licentiate thesis is to increase knowledge about the implications of working as a non-career firefighter in order to understand how challenges and commitment affect retention. Retention of non-career firefighters (for example volunteer or part-time firefighters) is a well-known, multifaceted challenge in several countries. These non-career firefighters account for the m
Purpose: Acute trauma-related rotator cuff tears are believed to have better healing potential than chronic tears due to less degenerative changes of the tendons. However, the histopathological condition of tendons from trauma-related tears is not well investigated. The purpose of this study was to explore specific histopathological features in tendons from acute trauma-related full-thickness rota
AIMS/INTRODUCTION: An increased risk of diabetes mellitus has been reported in primary aldosteronism, but the pathogenesis of glucose intolerance between the primary aldosteronism subtypes remains unclear. This study aimed to evaluate glucose metabolism in oral glucose tolerance test between aldosterone-producing adenoma and idiopathic hyperaldosteronism, and characterize patients with improved gl
Recent industrial interest in producing smaller volumes of products in shorter time frames, in contrast to mass production in previous decades, motivated the introduction of human–robot collaboration (HRC) in industrial settings, as an attempt to increase flexibility in manufacturing applications by incorporating human intelligence and dexterity to these processes. This thesis presents methods for
OBJECTIVE: : To estimate the association between an Apgar score of less than 7 at 5 minutes after birth and long-term cognitive function. METHODS: : A linkage between the Swedish Medical Birth Registry and the Swedish School Grade Registry was performed. All singletons born from 1973 to 1986 after 36 6/7 weeks of gestation to Swedish-born women were included. Fetuses that were stillborn, newborns
In pulse-echo (PE) ultrasound measurements, the use of focused transducers is desirable for quantitative assessment of bone characteristics because of the attenuation in the overlying soft tissues. However, the variable thickness and composition of the soft tissue overlying bone affect the focal depth of the ultrasound beam and induce errors into the measurements. To compensate for the attenuation
