This paper applies the GARCH-MIDAS (mixed data sampling) model to examine whether information contained in macroeconomic variables can help to predict short-term and long-term components of the return variance. A principal component analysis is used to incorporate the information contained in different variables. Our results show that including low-frequency macroeconomic information in the GARCH-
To estimate the prevalence, determine the subgroups at risk, and the outcomes of patients with systemic sclerosis (SSc) and gastric antral vascular ectasia (GAVE).
In this paper, an inverse source reconstruction method with great potential in radome diagnostics is presented. Defects, e.g., seams in large radomes, and lattice dislocations in frequency selective surface (FSS) radomes, are inevitable, and their electrical effects demand analysis. Here, defects in a frequency selective radome are analyzed with a method based on an integral formulation. Several f
Although case studies exist of the influence of non-governmental organisations in international environmental negotiations, theoretical conclusions remain scattered, and the separation in previous literature between the study of environmental non-governmental organisations (ENGOs) and business and industry non-governmental organisations (BINGOs) reduces the generalisability of conclusions. The con
The innate immune system relies to a great deal on the interaction of pattern recognition receptors with pathogen- or damage-associated molecular pattern molecules. Extracellular histones belong to the latter group and their release has been described to contribute to the induction of systemic inflammatory reactions. However, little is known about their functions in the early immune response to an
This article addresses the research gap of water desecuritisation and advances an interdisciplinary approach within the issue area of peacebuilding. It draws upon three strands of research: security, peacebuilding and transboundary water management. The article examines three core questions: (1) how is desecuritisation conceptualised and understood in theory as well as within the context of water
The article uses conceptual metaphor theory in order to analyse how the concept of “copy” in copyright law is expanding in a digital society to cover more phenomena than it originally did. For this purpose, the legally accepted model for valuing media files in the case against The Pirate Bay (TPB) is used in the analysis. When four men behind TPB was convicted in District Court of Stockholm, Swede
AimsTo assess the variation in ovarian carcinoma type diagnosis among gynaecological pathologists from Nordic countries, and whether a rationally designed panel of immunohistochemical markers could improve diagnostic reproducibility. Methods and resultsEight pathologists from four countries (Sweden, Denmark, Norway, and Finland) received an educational lecture on the diagnosis of ovarian carcinoma
The human leukocyte antigen (HLA) is the main genetic determinant of multiple sclerosis (MS) risk. Within the HLA, the class II HLA-DRB1*15:01 allele exerts a disease-promoting effect, whereas the class I HLA-A*02 allele is protective. The CIITA gene is crucial for expression of class II HLA molecules and has previously been found to associate with several autoimmune diseases, including MS and typ
The aviation business has gone through a process of radical restructuring during the latest decades. De-regulation and fierce competition from low-cost carriers have put traditional flag carriers under pressure, resulting in falling fares. In this cost cutting process, service quality aboard has in many cases fallen at the same time as the glamorous image of aviation partly remains. This process h
A U-Pb dating of titanite from an augen granitoid mylonite in the Druksiai-Polotsk Deformation Zone has yielded a concordant age of 1534 +/- 9 Ma. This light brown titanite follows the foliation in the host rock and was obviously formed during retrogression from amphibolite to epidote-amphibolite facies and coeval mylonitization. Shear zones of the same age are known in southern and central Sweden
Two-dimensional polarization fluorescence imaging of single light harvesting complexes 2 (LH2) of Rps. acidophila was carried out to investigate the polarization properties of excitation and fluorescence emission simultaneously, at room temperature. In two separate experiments we excited LH2 with a spectrally narrow laser line matched to the absorption bands of the two chromophore rings, B800 and
Every two seconds, someone across the globe suffers a symptomatic stroke. 'Silent' cerebrovascular disease insidiously contributes to worldwide disability by causing cognitive impairment in the elderly. The risk of cerebrovascular disease is disproportionately higher in low to middle income countries where there may be barriers to stroke care. The last two decades have seen a major transformation
Several treatment alternatives for food waste can result in both energy and nutrient recovery, and thereby potential environmental benefits. However, according to the European Union waste management hierarchy, waste prevention should be the prioritized strategy to decrease the environmental burdens from all solid waste management. The aim of the present study was therefore to investigate the poten
As a lecturer in mathematics for first-year university students one faces several challenging problems; big classes, low motivation and a high level of abstraction. Based on interviews with several experienced university lecturers in mathematics, we present a toolbox of tips and tricks intended to be used when reflecting over one's own teaching in order to improve it.
The intensities of the X and A valence photoelectron lines of N-2 have been found to display Fano line shapes as a function of photon energy around the N 1s -> Rydberg excitations. The vibrational intensity distributions of these photoelectron lines change at the N 1s -> 3s sigma and 3p pi resonances. These effects indicate interference between direct and resonant photoionization channels. Our num
We consider a random synaptic pruning in an initially highly interconnected network. It is proved that a random network can maintain a self-sustained activity level for some parameters. For such a set of parameters a pruning is constructed so that in the resulting network each neuron/node has almost equal numbers of in- and out-connections. It is also shown that the set of parameters which admits
Previous studies have shown gender differences in preoperative status and outcome of spine surgery. This study explores whether gender differences in preoperative demographics exist in patients scheduled for lumbar disc herniation (LDH) surgery.
Tri-isopropylsilyl thio-glycosides (TIPS S-glycosides) were synthesized through base promoted SN2 substitution of glycosyl halides with TIPS-SH or by Lewis acid promoted glycosylation of TIPS-SH with glycosyl acetates or p-methoxyphenyl glycosides. Various thioglycoside derivatives were obtained in high yields by one-pot fluoride-mediated de-silylation and thiol alkylation with alkyl halides or Mi
