Arbetet är utfört åt skogsforskningsstationen Mógilsá som ligger strax norr om Reykjavik. Forskningen inom Mógilsá bedrivs inom delar av eller för hela Island med inriktning inom exempelvis dendrokronologi, proveniensförsök, och studier av insekter. Sedan 1900-talets början har inplantering av exotiska trädarter blivit allt vanligare och i en allt större skala. Syften med inplanteringen är bland aThis study was made in an attempt to give the forest research centre Mógilsá a produced tetratherm map and a better understanding of how topography and temperature influence the growth of two tree species. The digital tetratherm map model, covering the northern part of Iceland, was developed to investigate the correlation between tetratherm and the growth of Picea sitchensis and Larix (sukaczewii

Innovation may be described as the new religion of the 21st Century. The acceleration of technical change and innovation has created a new competitive dynamism, which poses a challenge to the present competition policy. This competitive dynamism is particularly apparent in those markets that are referred to as constituting the ''new economy''. These markets are characterised by hig

States have discretion what concrete measures to undertake to fulfil their primary positive obligations under the ECHR. If a violation of these obligations is found, states also have discretion how to execute the judgment to comply with their secondary obligations. Yet, when the Court reasons to reach a conclusion whether there has been a violation, it necessarily specifies possible concrete measu

BACKGROUND: Despite the increasing longevity of the world's population, with an unprecedented rise in the number of people who need palliative care (PC), there has been sparse research regarding palliative care for older people, especially when it comes to comparison of PC between healthcare systems and cultures. The aim of this systematic scoping review was to identify the characteristics of the

BACKGROUND: Since the "War on Cancer" was declared in 1971, the United States alone has expended some $300 billion on research, with a heavy focus on the role of genomics in anticancer therapy. Voluminous data have been collected and analyzed. However, in hindsight, any achievements made have not been realized in clinical practice in terms of overall survival or quality of life extended. This migh

Objectives: To study in vivo gray matter (GM) volumes of the nucleus basalis of Meynert (nbM) in different parkinsonian syndromes and assess their relationship with clinical variables. Methods: T1-weighted magnetic resonance images from patients with progressive supranuclear palsy (PSP, N = 43), multiple system atrophy (MSA, N = 23), Parkinson’s disease (PD, N = 26), and healthy controls (HC, N =

Results from the radiological environmental monitoring of the European Spallation Source (ESS) are presented for year 2020.Among the 63 environmental samples analysed for gamma emitting radionuclides, no elevated levels of anthropogenic radioactivity were observed. All samples (except two samples of lichen) had activity concentrations below the MDA for the natural radionuclides as well as 137Cs, a

Objectives: To investigate absolute and relative risk of serious infections in adult/elderly inflammatory bowel disease (IBD) diagnosed 2002–2017. Methods: Nationwide, register-based cohort study of Swedish patients with IBD compared with general population matched reference individuals with regard to time to first serious infection, equal to hospital admission. Multivariable Cox regression estima

Anomaly detection is the process of identifying unexpected data samples in datasets. Automated anomaly detection is either performed using supervised machine learning models, which require a labelled dataset for their calibration, or unsupervised models, which do not require labels. While academic research has produced a vast array of tools and machine learning models for automated anomaly detecti

Microarray technology has revolutionized genetic analysis. However, limitations in genome analysis has lead to renewed interest in establishing 'omic' strategies. As we enter the post-genomic era, new microarray technologies are needed to address these new classes of 'omic' targets, such as proteins, as well as lipids and carbohydrates. We have developed a microarray platform that combines self- a

BACKGROUND: Although coronary events (CE) and ischemic stroke share many risk factors, there are also some important differences. The aim of this paper was to assess the association of risk factors in relation to incident CE and ischemic stroke and to evaluate the heterogeneity in patterns of risk factors between the two outcomes.METHOD: Traditional risk factors and inflammatory markers associated

Hepatitis B virus (HBV) infection remains a major public health threat in the Middle East and North Africa (MENA). Phylogenetic analysis of HBV can be helpful to study the putative transmission links and patterns of inter-country spread of the virus. The objectives of the current study were to analyze the HBV genotype/sub-genotype (SGT) distribution, reverse transcriptase (RT), and surface (S) gen

The problem of equivalence in terms of multistability properties between gene regulatory network models of different dimensionality has been recently addressed by Schittler et al.(2013). The authors in that work proposed construction rules for a high-dimensional dynamical system, when given a low-dimensional dynamical system and the high-dimensional network structure. However, the proof therein wa

The past years have seen an unprecedented growth in the ICT economy that has fundamentally altered business models and consumer cultures. Many of the changes this has implied are specifically relevant for tourism, a sector that perhaps more than any other is exposed to and implicated in digital innovation, consumer-business interrelationships, and platform reliance. Most studies of the digitalizat

Background: As many countries seek to slow the spread of COVID-19 without reimposing national restrictions, it has become important to track the disease at a local level to identify areas in need of targeted intervention. Methods: In this prospective, observational study, we did modelling using longitudinal, self-reported data from users of the COVID Symptom Study app in England between March 24,

The number of degrees of freedom is a crucial parameter in many electromagnetic problems. In for example modern communication systems spatial diversity is often employed through multiple beams to enhance capacity and reliability. However, while the degrees of freedom can be computed, their connection to physical quantities is not as easily understood. To address this issue, this paper proposes a s

Purpose: Validation of artificial intelligence (AI) algorithms in digital pathology with a reference standard is necessary before widespread clinical use, but few examples focus on creating a reference standard based on pathologist annotations. This work assesses the results of a pilot study that collects density estimates of stromal tumor-infiltrating lymphocytes (sTILs) in breast cancer biopsy s

Many long-term childhood cancer survivors suffer from treatment-related late effects, which may occur in any organ and include a wide spectrum of conditions. Long-term follow-up (LTFU) is recommended to facilitate early diagnosis and to ensure better health outcomes. Due to the heterogeneity of these sequelae, different specialists work together in the diagnosis and treatment of these conditions.

Objectives: To evaluate outcomes of management without surgical revascularization in patients with acute lower limb ischemia (ALI) in a population-based setting. Design: Retrospective observational population-based study. Materials: Patients from Malmö, Sweden, hospitalized for ALI between 2015 and 2018. Methods: In-hospital, surgical, radiological, and autopsy registries were scrutinized for desc
