Online Optimisation of the MAX IV 3 GeV Ring Dynamic Aperture

In order to improve the resilience of the MAX IV 3 GeV ring's beam to a horizontal dipole kick while at the design tunes (42.20, 16.28) the optimisation algorithm RCDS (Robust Conjugate Direction Search) was deployed. The algorithm was able to increase the horizontal acceptance by finding new settings for the sextupole and octupole magnets, whilst leaving the vertical acceptance virtually unchangeIn order to improve the resilience of the MAX IV 3 GeVring’s beam to a horizontal dipole kick while at the designtunes (42.20, 16.28) the optimisation algorithm RCDS (Robust Conjugate Direction Search) was deployed.

Pulse-Picking by Resonant Excitation (PPRE) for Timing Users at the MAX IV 3 GeV Storage Ring

At synchrotron light storage rings there is demand for serving both high-brilliance and timing users simultaneously. At many rings this is commonly achieved by operating fill patterns with gaps of sufficient length, but this is not favorable for rings that operate with passive harmonic cavities to damp instabilities and increase Touschek lifetime by lengthening the bunches. For such rings, gaps in

Spirituality among Iranian nursing students during undergraduate study

Background Nursing students are expected to deliver holistic care in their upcoming career. Developing spirituality during nursing training is poorly understood. Objectives The current study aimed to explore the process of developing spirituality among Iranian nursing undergraduates. Patients and Methods The study employed Grounded theory approach and purposive sampling with maximum variation to s

Förändrad syn på glaukom : I första hand en optikusneuropati, inte en sjukdom i ögats kammarvinkel

Glaucoma is now considered to be primarily an optic neuropathy, not a disease of the anterior chamber angle. Although intraocular pressure remains a crucial variable, the relationship between increased intraocular pressure and glaucoma is now recognised as being less simple than formerly believed. The new approach to the disease is reflected in a review by the National Board of Health and Welfare

Early Manifest Glaucoma Trial : Design and baseline data

Objectives: The Early Manifest Glaucoma Trial (EMGT) will evaluate the effectiveness of reducing intraocular pressure (lOP) in early, previously untreated open-angle glaucoma. Its secondary aims are to explore factors related to glaucoma progression and to study the natural history of the disease. This article describes the EMGT design and presents baseline data. Design: Randomized, clinical trial

Pitfalls of automated perimetry in glaucoma diagnosis

Perimetry is a cornerstone in glaucoma management. The detection of glaucomatous visual field loss is of crucial importance for diagnosing the disease. Automated threshold perimetry makes thorough testing of the central visual field very possible and high-quality data are often achieved. Certain factors, however, may hamper the visual field examination or visual field interpretation. Many diseases

Response surface methodology and artificial neural network modeling of an aqueous two-phase system for purification of a recombinant alkaline active xylanase

A two-stage polyethylene glycol (PEG)-phosphate aqueous two-phase system was used for purification of a highly thermostable and alkaline active recombinant xylanase. Response surface methodology (RSM) and artificial neural network (ANN) have been used to develop predictive models for simulation and optimization of purification process. Effects of pH, PEG molecular weight, concentrations of phospha

Chemical relationships of ambers using attenuated total reflectance Fourier transform infrared spectroscopy

Amber is known for its remarkably well-preserved fossils, but the chemical complexity of amber and its history are less well known. Amber is highly variable in both its physical and chemical properties, which are dependent on factors such as the source tree and the diagenetic history. Amber from a given locality therefore has a unique chemical composition. Fourier transform infrared (FTIR) spectro

Increased molecular mobility in humid silk fibers under tensile stress

Silk fibers are semicrystalline nanocomposite protein fibers with an extraordinary mechanical toughness that changes with humidity. Diffusive or overdamped motion on a molecular level is absent in dry silkworm silk, but present in humid silk at ambient temperature. This microscopic diffusion distinctly depends on the externally applied macroscopic tensile force. Quasielastic and inelastic neutron-

Smoking-induced risk of future cardiovascular disease is partly mediated by cadmium in tobacco : Malmö Diet and Cancer Cohort Study

Background: Smoking is a strong risk factor for cardiovascular disease (CVD) and causes exposure to cadmium, which is a pro-atherosclerotic metal. Cadmium exposure has also been shown to increase the risk of CVD, even after adjustment for smoking. Our hypothesis was that part of the risk of CVD in smokers may be mediated by cadmium exposure from tobacco smoke. We examined this hypothesis in a medi

Sjögren's syndrome: epidemiological risk factors and biomarkers

Primary Sjögren’s syndrome (pSS) is an autoimmune disease, primarliy affecting women, characterised by inflammation and destruction of exocrine glands with a prevalence of 0.01-0.09%. About one-third of the patients also suffer from extraglandular manifestations e.g. inflammation in the lungs, kidneys, skin or nerves. Apart from dyness symptoms, patients often suffer from fatigue and pain. Little

Reviews and taxonomies

This chapter summarizes the existing review articles in the field of monitoring and diagnosing older adults at risk of health deterioration, in the context of smart-homes. We provide taxonomy of these notable review articles, characterizing their aims and reviewing approaches of proposed monitoring systems capable of detecting health threats in smart-home settings. We included reviews, which focus

Datasets

Publicly available datasets constitute the ground to evaluate and compare the performance of proposed approaches for monitoring older patients at home. In this chapter, we shed light on the importance of using datasets as a benchmarking tool for comparing various monitoring techniques for detecting the health threats, which we discussed in the previous chapters. The methods, which are tested by us

Unsupervised learning of action primitives

Action representation is a key issue in imitation learning for humanoids. With the recent finding of mirror neurons there has been a growing interest in expressing actions as a combination meaningful subparts called primitives. Primitives could be thought of as an alphabet for the human actions. In this paper we observe that human actions and objects can be seen as being intertwined: we can interp
