We study several problems of clearing subgraphs by mobile agents in digraphs. The agents can move only along directed walks of a digraph and, depending on the variant, their initial positions may be pre-specified. In general, for a given subset S of vertices of a digraph D and a positive integer k, the objective is to determine whether there is a subgraph H = (VH, AH) of D such that (a) S ⊆ VH, (b
Two approaches to the macro basis function (MBF) method that target interconnected subdomains have been adapted to finite linear arrays, and benchmarked against each other in order to estimate their performance with respect to the strong near field coupling that occurs under the endfire mode operation. The methods, here referred to as methods A and B, are based on the synthetic function and charac
The evolution of phenotypic plasticity requires a number of conditions. Selection of plasticity is favoured when the organism experience environmental change, costs are low and cues are reliable about the environmental heterogeneity. However, organisms living in stable environments, not showing constitutive traits but a large amount of plasticity, are predicted to demonstrate high rates of gene fl
What can be done to raise awareness of the significance of sense- and soundscape for health, wellbeing and communication? A massive body of research is being conducted in the sound environment field today with important discoveries especially on relationship between noise and health. Outcomes of this research slowly pours up into society, raising warnings of health and environmental risks, not sel
An explicit expression, free from adjustable parameters, is derived for the effective pair interaction between charged colloidal spheres at high concentration in a medium containing an electrolyte. This is accomplished by first considering the electrostatic interaction between two infinite charged plates placed in a stack of identical plates. These act as a reservoir defining the chemical potentia
Comparisons of the strength and form of phenotypic selection among groups provide a powerful approach for testing adaptive hypotheses. A central and largely unaddressed issue is how fitness and phenotypes are standardized in such studies; standardization across or within groups can qualitatively change conclusions whenever mean fitness differs between groups. We briefly reviewed recent relevant li
Macrolide antibiotics are used as anti-inflammatory agents, e.g., for prevention of exacerbations in chronic obstructive pulmonary disease and cystic fibrosis. Several studies have shown improved outcomes after the addition of macrolides to -lactam antibiotics for treatment of severe community-acquired pneumonia. However, a beneficial effect of macrolides in treating Gram-negative bacterial airway
A heterogeneous distribution of crosslinker in micro-hydrogels (microgels) results in a non-uniform polymer density inside the particles. Identifying the morphology of the hydrogel backbone enables a bottom-up approach towards the structural and rheological properties of microgel systems. On a local level we use a Flory-Rehner inspired model that focuses on highly swollen networks, characterized b
The human cathelicidin peptide LL-37 has antimicrobial and anti-biofilm functions, but LL-37 may also damage the host by triggering inflammation and exerting a cytotoxic effect, thereby reducing host cell viability. Human plasma mitigates LL-37-induced host cell cytotoxicity but the underlying mechanisms are not completely understood. Apolipoprotein A-I (ApoA-I) is a plasma protein endowed with at
Background: Chronic rhinosinusitis with and without nasal polyps (CRSw/sNP) are common conditions decreasing health-related quality of life (HRQOL). Individual symptoms capable of predicting outcome after endoscopic sinus surgery (ESS) are poorly defined, and the indirect costs of CRS is rarely reported in Europe. Methodology: Patients with CRSw/sNP admitted for ESS were prospectively enrolled. Pa
In recent years, the increase of the global incidence of obesity and obesity-related disorders has been associated with metabolic imbalance and low grade inflammation. Fat-rich meals and diets contribute importantly to those alterations. The aim of this work was to evaluate the impact of exchanging butter by Hass avocado-oil on postprandial metabolic parameters in healthy overweight volunteers con
Cocoa is a well acknowledged polyphenol-rich functional product. However, the mechanisms and effects of cocoa products on glucose metabolism and appetite regulation are not clear. A crossover randomised study was carried out in twenty (4male; 16female) healthy middle-age (62.6 ± 6.5 yr) subjects with normal BMI (23.0 ± 2.0 kg/m2). Effects on postprandial glucose-, insulin- and subjective appetite
Introduction: The importance of mobile health has increased during recent years but few studies have described the use of apps among persons with neurological disabilities. Aim: The aim of this paper was to describe how persons ageing with a neurological disability experience barriers and facilitators in relation to using apps in everyday life. Method: A qualitative approach was used. 16 persons w
This paper presents a study of WWγ and WZγ triboson production using events from proton–proton collisions at a centre-of-mass energy of s=8TeV recorded with the ATLAS detector at the LHC and corresponding to an integrated luminosity of 20.2 fb- 1. The WWγ production cross-section is determined using a final state containing an electron, a muon, a photon, and neutrinos (e). Upper limits on the prod
The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures. Backorder costs are traditionally assumed to be linear, whereas we consider structures that are more general functions of the customers’ time in backorder. The system studied is a two-echelon system with one central warehouse and a number of local sites,The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures.

Global engagement can impact firm organization and the occupations firms need. We use a simple task-based model of the firm's choice of occupational inputs to examine how that choice varies with global engagement. We reveal a robust and causal relationship between global engagement and the skill mix of occupations within firms, using Swedish matched employer-employee data that link firms and the l
