The number concentration of cloud droplets determines several climatically relevant cloud properties. A major cause for the high uncertainty in the indirect aerosol forcing is the availability of cloud condensation nuclei (CCN), which in turn is highly sensitive to atmospheric new particle formation. Here we present the effect of new particle formation on anthropogenic aerosol forcing in present-d
Ulceration of primary melanomas is associated with poor prognosis yet is reported to predict benefit from adjuvant interferon. To better understand the biological processes involved, clinicopathological factors associated with ulceration were determined in 1804 patients. From this cohort, 348 primary tumor blocks were sampled to generate gene expression data using a 502-gene cancer panel and 195 b
The majority of herbaceous plants are connected by arbuscular mycorrhizal (AM) fungi in complex networks, but how this affects carbon (C) and phosphorus (P) allocation among symbionts is poorly understood. We utilized a monoxenic AM system where hyphae from donor roots colonized two younger receiver roots of varying C status. AM fungal C allocation from donor to receiver compartments was followed
The goal of this paper is to determine whether the photoplethysmography (PPG) can replace the ECG-based detection of heart rate turbulence. Using the PPG, classification of ventricular premature beats (VPBs) is accomplished with a linear classifier. The two conventional parameters turbulence onset and slope are studied together with a recently introduced parameter characterizing turbulence shape.
There is a growing interest in the prospects of community energy projects to increase energy access for the world's poor. Yet it is not readily apparent how community energy projects can be organized to be successful in the long-term. By utilizing information from four case studies, this work creates a general framework for organizing community energy projects in developing countries. Using th
A system we denote Seg2Pose is presented which converts pixel coordinate tracks, represented by instance segmentation masks across multiple video frames, into world coordinate pose tracks, for road users seen by static surveillance cameras. The road users are bound to a ground surface represented by a number of 3D points and does not necessarily have to be perfectly flat. The system works with one
Aims: Ischaemic coronary artery disease (CAD) remains the leading cause of mortality globally due to sudden death and heart failure (HF). Invasive coronary angiography (CAG) is the gold standard for evaluating the presence and severity of CAD. Our objective was to assess temporal trends in CAG utilization, patient characteristics, and prognosis in HF patients undergoing CAG at a national level. Me
Migration distance and seasonal redistribution patterns may vary between and within bird populations. A common pattern is leap-frog migration, in which northerly breeding populations migrate farther and winter south of more southerly breeding populations. Another common pattern is difference in migration distances between males and females within the same population. Evidently different population
Decision-making in risk management reflects a normative choice of approach. This dissertation is concerned with the possibility of putting the decision in focus by employing an optimum decision criterion within a utility-based approach. The dissertation describes a cost-benefit analysis of separation distance, a risk-reducing measure used in land use planning in the vicinity of hazardous installat
This chapter investigates nominals in the early monolingual acquisition of Swedish. The major morphological properties of nominals in the adult grammar are described with regard to gender, number, definiteness, and nominal-internal agreement between determiner, adjective and noun. I summarise the empirical findings in the existing literature on the acquisition of nominals for Swedish children betw
We present fully self-consistent results for the self-energy of the electron gas within the GW approximation. This means that the self-consistent Green’s function G, as obtained from Dyson’s equation, is used not only for obtaining the self-energy but also for constructing the screened interaction W within the random-phase approximation. Such a theory is particle and energy conserving in the sense
The aim of the study was to examine parents’ experiences of personal assistance of their child's personal assistance in the home. The focus set on the relationship to the assistant. The material has been gathered through semi-structured interviews and the sample group consisted of four parents. The approach is ethno methodological. Furthermore, the concepts of backstage and frontstage from Gof
This thesis examines how asymmetric information causes issues in online markets and how it leads to mispricing between buyers and sellers. Asymmetric information and its negative effect on traditional markets have been examined by earlier studies but we strive to test the the theory on an online market. This is tested by looking at how review systems affects the market and whether this information

Remote sensing is increasingly being used as a cost-effective and practical solution for the rapid evaluation of impacts from wildland fires. The present study investigates the use of the support vector machine (SVM) classification method with multispectral data from the Advanced Spectral Emission and Reflection Radiometer (ASTER) for obtaining a rapid and cost effective post-fire assessment in a
