Shunting yards are one of the main areas impacting the reliability of rail freight networks, and delayed departures from shunting yards can further also affect the punctuality of mixed-traffic networks. Methods for automatic detection of departures, which are likely to be delayed, can therefore contribute towards increasing the reliability and punctuality of both freight and passenger services. In
Tack vare kikare, teleskop och spektroskop har vi kunnat blicka längre ut i Universum än som någonsin hade varit möjligt med bara ögonen. På samma sätt finns det ett helt Universum åt andra hållet. Bland celler, molekyler, ände ner till atomer. Men nere i atomvärlden är det inte teleskop som behövs. Nej, där tar vi hjälp av de fiffiga små neutronerna själva. Thanks to binoculars, telescopes and spectroscopes, we have been able to look further out into the Universe than would ever have been possible with the naked eye. In the same way, there is a whole Universe in the other direction. Among cells, molecules, and down to atoms. But down in the nuclear world, telescopes are not needed. No, there we take the help of the small neutrons themselves.
Streptococcus pyogenes is known to cause both mucosal and systemic infections in humans. In this study, we used a combination of quantitative and structural mass spectrometry techniques to determine the composition and structure of the interaction network formed between human plasma proteins and the surfaces of different S. pyogenes serotypes. Quantitative network analysis revealed that S. pyogene
The freedom for children to autonomously move and play in their neighborhood, i.e. their independent mobility, has implications for their health, wellbeing and development. How children and parents experience the outdoor environment is vital to children’s independent mobility. Well-lit outdoor environments are, among adults, associated with perceived visual accessibility, safety, and walking. Howe
Momentary contentment theory is a grounded theory explaining how to find safety and balance in life despite an awareness of life´s unpredictability. The theory is based on communion with others, proactivity and acceptance. It explains cognitive and emotional ways of finding a sense of safety and enjoyment despite illness and accidents. Three concepts are central to Momentary contentment theory: do
In this text, concerning 50 years of Ethnologia Scandinavica, I shall follow ethnological development in the context of the object of study that in itself came to influence the shape and character of Nordic ethnology as a discipline.
Model Predictive Control (MPC) is an efficient point-to-point trajectory-generation method for robots that can be used in situations that occur under time constraints. The motion plan can be recalculated online to increase the accuracy of the trajectory when getting close to the goal position. We have implemented this strategy in a Franka Emika Panda robot, a redundant collaborative robot, by exte
Experimental studies are carried out to investigate the heat transfer performance of six different arrangements of truncated ribs in internal cooling channel by fixing the Reynolds number. The convective heat transfer mechanisms of the considered cases are detailed and analyzed based on the fluid flow characteristics by using three dimensional numerical simulations. The results show that among six
Bacterial endotoxin is a potent inflammatory antigen abundant in the human intestine. Endotoxins circulate in the blood at low concentrations in all healthy individuals. Elevated levels of circulatory endotoxins may cause inflammation with the development of chronic disease, either affecting metabolism, neurological disease, or resistance to viral and bacterial infections. The most important endot
Stories are being increasingly recognised for their potential as creators, not only depicters, of change. As such, they are receiving greater interest within sustainability science, not least in the approaches specifically focused on transformative processes of co-creation. But while highly powerful, stories are confined by both inherent and external frameworks that, if not acknowledged, limit the
Semialgebraic proof systems have been studied extensively in proof complexity since the late 1990s to understand the power of Gröbner basis computations, linear and semidefinite programming hierarchies, and other methods. Such proof systems are defined alternately with only the original variables of the problem and with special formal variables for positive and negative literals, but there seems t
In this release note we describe the 1.2 update to NLOX, a computer program for calculations in high-energy particle physics. New features since the 1.0 release and other changes are described, along with usage documentation. New version program summary: Program title: NLOX Developer's repository link: http://www.hep.fsu.edu/~nlox Licensing provisions: CC BY NC 3.0 Programming language: C++. Fortr
Law enforcement demands self-management, intrinsic motivation, high energy levels and tolerance to stress. The concept of self-management might involve both autonomy and responsibility. Autonomy and responsibility, however, are often considered and measured as the same construct even thought at a conceptual level they can be seen as a separate dual construct. Our aims were: (a) to investigate the
Objectives: Cognitive aging has been extensively investigated using both univariate and multivariate analyses. Sophisticated multivariate approaches such as graph theory could potentially capture unknown complex associations between multiple cognitive variables. The aim of this study was to assess whether cognition is organized into a structure that could be called the “cognitive connectome,” and
A growing body of evidence suggests that the deep oceans during the early Paleozoic Era were widely oxygen deficient, despite evidence for increased marine oxygenation during the Neoproterozoic. However, the temporal and geographic extents and dynamics of reducing marine conditions within these oceans are not well understood. Here, we investigate marine redox history during the Drumian through the
(1) Background: Reconditioning of the paraspinal lumbar extensor muscles by isolated lumbar extension resistance exercises (ILEX) has shown good clinical results for patients with chronic unspecific low back pain. However, the clinical value and safety for patients with specific spine pathologies is unclear. In this study, clinical outcome and influencing factors were retrospectively analyzed for
