The problem of finding the controller that optimizes the expected H2-norm of an uncertain system is solved in closed form for a class of problems including such signal processing applications as feedforward design, channel equalization, noise cancellation etc. The method uses covariance information on model uncertainty and does therefore match information obtainable from standard system identifica

BACKGROUND—: Myeloid cells are central to atherosclerotic lesion development and vulnerable plaque formation. Impaired ability of arterial phagocytes to uptake apoptotic cells (efferocytosis), promotes lesion growth and establishment of a necrotic core. The transcription factor Interferon Regulatory Factor (IRF)-5 is an important modulator of myeloid function and programming. We sought to investig

Economic divisions have deepened in Sweden in recent years, and lone mothers are one group where the poverty rate has increased most (Salonen 2014). At the same time, di erences between the situations of lone mothers have also increased (Lundqvist 2014). As a consequence, intergenerational support from grandparents in terms of care and nancial transfers are important (see also Halleröd 2008). Thi

A 2009 G20 official document stated that the era of banking secrecy is over but is it? If banking secrecy is the result of market mechanisms, it suggests that worldwide demand and supply are likely to remain for a long time to come. Since the Global Financial Crisis, many countries have fought to combat banking secrecy, yet it permeates both national and international industries, and global effort

Endohedral lanthanide ions packed inside carbon nanotubes (CNTs) in a one-dimensional assembly have been studied with a combination of high resolution transmission electron microscopy (HRTEM), scanning transmission X-ray microscopy (STXM), and X-ray magnetic circular dichroism (XMCD). By correlating HRTEM and STXM images we show that structures down to 30 nm are resolved with chemical contrast and

BACKGROUND: Alzheimer's disease (AD)-linked β-amyloid (Aβ) accumulates in multivesicular bodies (MVBs) with the onset of AD pathogenesis. Alterations in endosomes are among the earliest changes associated with AD but the mechanism(s) that cause endosome enlargement and the effects of MVB dysfunction on Aβ accumulation and tau pathology are incompletely understood.METHODS: MVB size and Aβ fibrils i

The limited available treatment options for patients with chronic lung diseases, such as fibrosis, lead to poor prognosis after diagnosis and short survival rates. An exciting new bioengineering approach utilizes de- and recellularization of lung tissue to potentially overcome donor organ shortage and immune reactions toward the received transplant. The goal of decellularization is to create a sca

BACKGROUND: Monitoring levels and trends in premature mortality is crucial to understanding how societies can address prominent sources of early death. The Global Burden of Disease 2016 Study (GBD 2016) provides a comprehensive assessment of cause-specific mortality for 264 causes in 195 locations from 1980 to 2016. This assessment includes evaluation of the expected epidemiological transition wit

BACKGROUND: The UN's Sustainable Development Goals (SDGs) are grounded in the global ambition of "leaving no one behind". Understanding today's gains and gaps for the health-related SDGs is essential for decision makers as they aim to improve the health of populations. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016), we measured 37 of the 50 health-relate

MOTIVATION: Neutrophil extracellular traps (NETs) are believed to be essential in controlling several bacterial pathogens. Quantification of NETs in vitro is an important tool in studies aiming to clarify the biological and chemical factors contributing to NET production, stabilization and degradation. This estimation can be performed on the basis of fluorescent microscopy images using appropriate

The porcine and human pathogen Streptococcus suis induces and degrades neutrophil extracellular traps (NETs) in vitro. In this study, we investigated the working hypothesis that NET degradation is mediated not only by the known secreted S. suis nuclease A (SsnA) but also by a so-far undescribed putative endonuclease A of S. suis (designated EndAsuis) homologous to the pneumococcal endonuclease A (

The formation of neutrophil extracellular traps (NETs) as a host innate immune defence mechanism has been shown to be the result of a novel cell death process called NETosis. The objective of this study was to investigate the role of cholesterol in the formation of NETs. To this end, primary human neutrophils were treated with different concentrations of methy-β-cyclodetxrin (MβCD) to reduce chole

In this paper we are investigating how project complexity is affecting the management of single projects in a multi-project environment. The project manager’s perspective is applied. A conceptual framework is developed in order to summarize how project complexity effect project management. The framework is applied to two cases and conclusions are drawn.

Metallic cast components inevitably contain defects such as shrinkage cavities which are inherent to the solidification process. Those defects are known to significantly alter the fatigue life of components. Yet very little is known, quantitatively, on the dangerosity of internal casting defects compared to surface ones. In this study, fatigue specimens containing controlled internal defects (shri
