Techniques for accurate, robust and efficient over-the-air testing for devices in the next generation communication system are important. This work aims at presenting the use of an aperture calibration technique, through which field values and power density values are reconstructed at an arbitrary plane in the near-field from a measurement of a separate plane for devices operating in 28-60 GHz. Th
A model for interaction between acoustic and elec- tromagnetic waves based on photoelasticity is presented. A radar equation based on physical, geometric and system parameters is shown, as well as a condition for maximizing interaction (equivalent to the Bragg condition in acousto-optics). The photoelastic model is used to implement a multiphysics simulation of the problem. The Bragg condition is
Wireless connectivity is becoming an important feature in cars, which together with recent developments in car design point to the need to accurately predict the performance of real antennas in simulation, to speed up the design cycle. However, it is challenging to accurately represent structurally complex real cars in simulation. This paper proposes a car model simplification approach for designi
Fundamental bounds on antenna and scattering metrics are presented in this paper utilizing volumetric method of moments. This makes it possible to investigate scenarios not solvable with classical surface method of moments which assumes that good conductors as used. One practical example is the study of plasmonic devices whose operation relies on the interaction between material properties and rad
Objectives: To quantify the effect of secondary screening for hip dislocations. Design: Retrospective analysis of hospital files from participants in a prospectively collected nationwide registry. Setting: Child healthcare centres and orthopaedic departments in Sweden. Participants: Of 126 children with hip dislocation diagnosed later than 14 days age in the 2000-2009 birth cohort, 101 had complet
Difficulty in obtaining bone tissue is an obstacle to studying epigenetics to understand gene–environment interactions, and their role in disease pathogenesis. Blood is an obvious alternative and in this proof of principle study, our aim was to systematically investigate whether blood is a viable surrogate for bone. We measured epigenome-wide DNA methylation at 850 K CpG sites in matched trabecula
Open Source Security and Dependency Vulnerability Management (DVM) has become a more vital part of the software security stack in recent years as modern software tend to be more dependent on open source libraries. The largest open source of vulnerabilities is the National Vulnerability Database (NVD), which supplies developers with machine-readable vulnerabilities. However, sometimes Common Vulner
BACKGROUND: Maldescended testes or cryptorchidism is a genital birth defect that affects 2-9% of all male new-borns. Over the last 40 years there have been reports of increased prevalence in countries like the US, the UK and the Scandinavian countries. This possible increase has in some studies been linked to a foetal exposure to chemical pollutants. In this matched case-control study, we analysed
The complement system is a well-characterized cascade of extracellular serum proteins that is activated by pathogens and unwanted waste material. Products of activated complement signal to the host cells via cell surface receptors, eliciting responses such as removal of the stimulus by phagocytosis. The complement system therefore functions as a warning system, resulting in removal of unwanted mat
Neutrophil extracellular traps (NETs) play a key role in the development of acute pancreatitis (AP). In the present study, we studied the role of extracellular cold-inducible RNA-binding protein (eCIRP), a novel damage-associated-molecular-pattern molecule, in severe AP. C57BL/6 mice underwent retrograde infusion of taurocholate into the pancreatic duct. C23, an eCIRP inhibitor, was given 1 h prio
Apolipoprotein M (apoM) was first identified and characterized to the apolipoprotein family in 1999. Human apoM gene is located in a highly conserved segment in the major histocompatibility complex (MHC) class III locus on chromosome 6 and codes for an about 23 kDa protein that structurally belongs to the lipocalin superfamily. ApoM is selectively expressed in hepatocytes and in the tubular epithe
Background: While discontinuation of COPD maintenance medication is a known problem, the proportion of patients with discontinuation and its geographical and sociodemographic distribution are so far unknown in Sweden. Therefore, we analyse this question by applying an innovative approach called multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA). Patients and Metho
In modern history, states have typically attempted to eliminate nomadism. Perhaps uniquely, Sweden reinforced nomadism among some of its Sámi population. In this chapter, I argue that the reason for this was twofold. First, reindeer herding necessitated nomadism, and it was thought to be the only economic contribution parts of the traditional Sámi land could provide. Second, a discourse of Boreali
The End of History was the title of Francis Fukuyama’s book (Fukuyama 1992), suggesting that with the demise of communism in the Soviet Union and Eastern Europe after the Berlin Wall, the consequence was that The Market had come out victorious after the Cold War, and now there was only one way ahead, and the savior capitalism would relentlessly lead to democracy. Now we know that this is not the c
Sweden attracted much attention as an interesting socioeconomic role model already in the 1930s, especially after Marquis Childs published his famous and influential book, The Swedish Middle Way (1936). Childs’ main argument was that the “Swedish model” was a successful “socialist” policy with a growing cooperative sector-as a counterbalance to the private sector-and effective crisis management. O
In this volume, the authors reflect on the question “what is socialism” as it pertains to today’s economy. There is particular emphasis on democratic socialism models as a potential alternative to classic authoritarian socialism. A number of topical questions are addressed such as: What is democratic socialism and is it feasible, or even viable? What can be learnt from existing democratic socialis
Introduction Children with appendicitis often present with complicated disease. The aim of this study was to describe the clinical management of pediatric appendicitis, and to report how disease severity and operative modality are associated with short- and long-term risks of adverse outcome. Materials and Methods A nationwide retrospective cohort study of all Swedish children (<18 years) diagnose
Persons who have survived a stroke might lower the risk of having recurrent strokes by adopting a healthier lifestyle with more exercise. One way to promote exercising is by fitness or exergame apps for mobile phones. Health and fitness apps are used by a significant portion of the consumers, but these apps are not targeted to stroke survivors, who may experience cognitive limitations (like fatigu
