The index of an invariant subspace M of a Banach space of analytic functions in the open unit disc is defined by ind M = dim M/zM. In this paper, we provide a strong link between high index and nontangential boundary behaviour of the functions in an invariant subspace.
A novel approach to the visualisation of soot is presented. It relies on a combination of laser-induced soot vapourisation and consecutive polarisation spectroscopy. Upon soot vapourisation, molecular fragments (for example, C-2) emerge, and may serve as effective tracers for soot. In this study we demonstrate that saturated polarisation spectroscopy on photoinduced C-2 can be exploited for soot d
Hyperresponsiveness to bronchoconstrictor stimuli is a major pathophysiologic feature of asthma, but the molecular mechanisms behind this are not fully understood. The release of TNF-alpha and IL-1 beta during the inflammatory process is believed to play an important role in airway hyperresponsiveness. We have previously demonstrated, using a murine in vitro model of chronic airway inflammation, t
This article proposes that people working with integration projects in Sweden are driven by a wish to help immigrants integrate into the host society. At the same time, however, the practices of multiculturalism tend to reproduce narratives that depict immigrants as threats to the host society and as inherently different from it. This tension can be analyzed through the intersections of a dilemma
Mass, heat and momentum transport processes are strongly coupled by internal chemical reforming reactions in planar design solid oxide fuel cell (SOFC) anodes. In this paper, a three-dimensional computational fluid dynamics approach is applied to simulate and analyze reforming reactions of methane and various transport processes in a duct relevant for SOFC anodes. The results show that the anode d
OBJECTIVE: The purpose of this study was to use transvaginal ultrasonographic measurements to find the thickness of the endometrium below which the risk of endometrial abnormality in women with postmenopausal bleeding is low. STUDY DESIGN: This multicenter study was carried out at eight clinics in four Nordic countries. The study included 1168 women with postmenopausal bleeding scheduled for curet
A quantitative validation of the microdialysis ethanol technique was performed in cat gastrocnemius muscle. Six to eight microdialysis probes were inserted into the isolated muscle preparation and perfused (0.5-10.0 microliters/min) with Krebs-Henseleit buffer containing between 5 and 1,000 mmol/l ethanol. Skeletal muscle blood flow was held constant in the range of 4-99 ml.100 g-1.min-1 by a serv
This paper investigates the effect of international research visits on promotion. Research visits may help to expand existing networks and promote knowledge transfer while at the same time ensuring career stability, identified as the main barrier to mobility in Europe and Japan. Using a dataset of 370 bioscience professors in Japan we find that international research visits have a positive effect
The possibility to manufacture hematopoietic stem cells (HSCs) in the laboratory would provide an indefinite source of cells for patients requiring bone marrow transplantation. Moreover, combined with the progress in gene editing techniques, it would provide a novel platform for gene and cell replacement therapies for a range of currently incurable congenic and acquired disorders. During my PhD, I
Neural transplantation can restore striatal dopaminergic neurotransmission in animal models of Parkinson's disease. It has now been shown that mesencephalic dopamine neurons, obtained from human fetuses of 8 to 9 weeks gestational age, can survive in the human brain and produce marked and sustained symptomatic relief in a patient severely affected with idiopathic Parkinson's disease. The grafts, w
This study examines the factors that have shaped the long-term evolution of the ICT industry in Sweden, 1950-2013. Exploiting a new historical micro-database on actual innovation output, the driving forces and technological interdependencies in the third industrial revolution are chronicled. The results of this study support some stylized facts about innovational interdependencies in general-purpo
Oxygenic photoautotrophs require mechanisms for rapidly matching the level of chlorophyll excited states from light harvesting with the rate of electron transport from water to carbon dioxide. These photoprotective reactions prevent formation of reactive excited states and photoinhibition. The fastest response to excess illumination is the so-called non-photochemical quenching which, in higher pla
Human postural control works as a dynamic feedback control system. The dynamic performance of postural control for anterior-posterior movements during upright posture are defined by three parameters. These parameters reflect the stiffness, the damping and the swiftness of a response to an induced perturbation. In the present study 23 normal subjects were investigated. Both with open and closed eye
BackgroundThe role of inflammation in Alzheimer’s disease (AD) and other cognitive disorders is unclear. In a well-defined mono-center population, we measured cytokines and chemokines in paired serum and cerebrospinal fluid (CSF) samples. MethodsConsecutive patients with AD (n = 30), stable mild cognitive impairment (SMCI, n = 11), other dementias (n = 11), and healthy controls (n = 18) were inclu
Background: Production of second-generation bioethanol and other bulk chemicals by yeast fermentation requirescells that tolerate inhibitory lignocellulosic compounds at low pH. Saccharomyces cerevisiae displays high plasticitywith regard to inhibitor tolerance, and adaptation of cell populations to process conditions is essential for reachingefficient and robust fermentations.Results: In this stu
