Pathological nystagmus is a symptom of oculomotor disease where the eyes oscillate involuntarily. The underlying cause of the nystagmus and the characteristics of the oscillatory eye movements are patient specific. An important part of clinical assessment in nystagmus patients is therefore to characterise different recorded eye-tracking signals, i.e. waveforms. Approach. A method for characterisat
Background: Compression of the greater occipital nerve (GON) may contribute to chronic headache, neck pain, and migraine in a subset of patients. We aimed to evaluate whether GON decompression could reduce pain and improve quality of life in patients with occipital neuralgia and chronic headache and neck pain. Methods: In this retrospective cohort study, selected patients with neck pain and headac
While the literature on failed Olympic bids has grown recently, not all failed bids have received attention. This article fills some gap in the literature. The aim of the study is to explore why the cities of Oslo and Stockholm – capitals in countries which are scoring high on various democracy indexes - choose to withdraw their Olympics bids. This is explored by drawing upon literature on urban g
We investigate robustness properties of the Generalized Proportional Allocation (GPA) policy that has been recently proposed for traffic signal control in urban networks. The GPA policy is fully decentralized, relies only on local information on the current congestion state, and requires no knowledge of the routing, the exogenous inflows, or the network structure. In previous work, we proved throu
Cerebral ischemia associated with subarachnoid haemorrhage (SAH) may have severe consequences for neuronal function leading to reversible or permanent neurological deficits. The excitatory amino acid neurotransmitters, such as glutamate, have been shown to be of particular importance for ischemic neuronal damage. In seven patients who underwent early surgery for a ruptured intracranial aneurysm, m
This paper is concerned with tracking of reference vectors in the continuous-discrete-time setting. For this end, an Itô stochastic differential equation, using the gyroscope as input, is formulated that explicitly accounts for the geometry of the problem. The filtering problem is solved by restricting the prediction and filtering distributions to the von Mises-Fisher class, resulting in ordinary
The mechanics of concrete can be understood comprehensively only if its heterogeneous microstructure is considered in experiments and simulations. We combine mesoscale modeling, in-situ X-ray computed tomography imaging, and in-situ 3D X-ray diffraction measurements for one of the first times to investigate the role of heterogeneities on macroscopic and microscopic responses in concrete. The focus
The outcome of the British Brexit referendum sent shockwaves across Europe. It sent signals about the future of the European Union (EU), not only to the Member States but also to the surrounding world. How to characterize the EU after Brexit? We address this problematic by investigating the metaphors applied to the EU in the Russian and Ukrainian press in the first week after the referendum. We fi
Low-quality health services are a problem across low- and middle-income countries. Information failure may contribute, as patients may have insufficient knowledge to discern the quality of health services. That decreases the likelihood that patients will sort into higher quality facilities, increasing demand for better health services. This paper presents results from a health survey in Nigeria to
In this study, effects of a dust hole and its location on the flow structure, endwall heat transfer and friction factor in a U bend channel used for a gas turbine blade tip cooling are numerically studied. The dust hole is placed on the endwall of a U bend at different locations. The U bend channel without dust hole is considered as Baseline. The Reynolds number ranges from 50,000 to 440,000. Resu
A nonlinear prediction method, developed based on the ideas gained from deterministic chaos theory, is employed: (a) to predict monthly runoff; and (b) to detect the possible presence of chaos in runoff dynamics. The method first reconstructs the single-dimensional (or variable) runoff series in a multi-dimensional phase space to represent its dynamics, and then uses a local polynomial approach to
We investigate the impact of impurity configuration on electronic and optical properties of YVO4 through application of plane-wave DFT. Since this crystal is a common host material for optical devices and it has been widely used as a phosphor and a laser host material, it is important to identify a correlation between impurity location and the intrinsic properties of the material. To further impro
The multi-objective optimal power management of multi-microgrid systems is solved in this paper. Minimizing the total cost and emission of the system are considered as the objective functions. The multi-objective particle swarm optimization algorithm is applied on a multi-microgrid system that consists of four microgrids each includes diesel generators, wind turbines, photovoltaic units, battery,
Within neutron imaging, different methods have been developed with the aim to go beyond the conventional contrast modalities, such as grating interferometry. Existing grating interferometers are sensitive to scattering in a single direction only, and thus investigations of anisotropic scattering structures imply the need for a circular scan of either the sample or the gratings. Here we propose an
Recent studies have found that explanations of the neolithisation of South Scandinavia based on dichotomies between migration (population replacement) and diffusion (in-group change) are insufficient if we want to understand the complexity and variation involved in what happened during the centuries around 4000 BCE. However, these contrasting narratives still overshadow discussions on change in So
Teamwork is considered something positive. While there is much research on teamwork in healthcare, research on teamwork in home care nursing is limited. As the need for home care nursing is likely to increase in the future, it is of great interest to investigate the circumstances associated with the implementation of teamwork in home care nursing. The present study compares the results from a larg
Previous research shows that transmission of attitudes in the family is gendered. However, there are limited findings about intergenerational transmission of risk attitudes and whether it is gendered. This study replicates the findings by Dohmen et al. (Rev Econ Stud 79(2):645–677) for Germany by using quantitative data from Burkina Faso in 2014 to analyze three different self-reported risk questi
Archaeological radiocarbon dating in coastal northern Hokkaido is challenged by the marine reservoir effect and the scarcity of materials with terrestrial carbon sources. This has contributed to gaps and general uncertainty in the timing of the region's culture-historical periods. The Late Holocene site of Hamanaka 2 on Rebun Island, featuring a stratified shell midden context with excellent prese
