A permanently available molecular-beam injection setup for controlled molecules (COMO) was installed and commissioned at the small quantum systems (SQS) instrument at the European x-ray free-electron laser (EuXFEL). A b-type electrostatic deflector allows for pure state-, size-, and isomer-selected samples of polar molecules and clusters. The source provides a rotationally cold (T ≈ 1 K) and dense
In this study, we present the initial results from a long-term initiative to develop a multi-millennial tree-ring width (TRW) chronology for subfossil oak (Quercus spp.) trees in South Scandinavia. We have constructed 40 TRW chronologies, primarily from oak trunks extracted from peatlands, archaeological sites, drainage ditches, and infrastructure projects, as well as some submerged material. The
This study employs computational algorithms to automatically identify and classify features in X-Ray fluorescence (XRF) microscopy images. Principal component analysis (PCA) and unsupervised machine learning algorithms, such as Gaussian mixture (GM) clustering, are implemented to label features on a collection of XRF maps of human atherosclerotic plaque samples. The investigation involves the hard
The interaction between a low angle grain boundary in front of a crack tip and the emerging plasticity from the tip of a microstructurally short edge crack subjected to fatigue loading has been studied. The modeling rests solely on discrete dislocations, were the geometry is described by dislocation dipole elements in a boundary element approach and the plasticity, restricted to one slip plane, to
Cosmogenic radionuclide records (e.g., 10Be and 14C) contain information on past geomagnetic dipole moment and solar activity changes. Disentangling these signals is challenging, but can be achieved by using independent reconstructions of the geomagnetic dipole moment. Consequently, solar activity reconstructions are directly influenced by the dipole moment uncertainties. Alternatively, the known
Background: The instant, single-sampling rule-out of acute myocardial infarction (AMI) is still an unmet clinical need. We aimed at testing and comparing diagnostic performance and prognostic value of two different single-sampling biomarker strategies for the instant rule-out of AMI. Methods: From the Biomarkers in Acute Cardiac Care (BACC) cohort, we recruited consecutive patients with acute ches
Analytical solutions for a one-line model for shoreline changes are employed to investigate the formation of two wave-dominated river delta coastlines, along with a small-scale laboratory experiment. Since the present analytical solution can be applied only to a river delta with infinite shorelines, a new analytical solution was developed to consider the effects of lateral boundaries to the evolut
Analogs of the incretin hormones Gip and Glp-1 are used to treat type 2 diabetes and obesity. Findings in experimental models suggest that manipulating several hormones simultaneously may be more effective. To identify small molecules that increase the number of incretin-expressing cells, we established a high-throughput in vivo chemical screen by using the gip promoter to drive the expression of
Background: There is growing attention and policy debate about the sharing of personal information that the modernization of electricity grids requires. This is particularly important for big data management in smart grids that needs access to data generated and sent through devices such as smart meters. Using the Nordic Countries as a case study, this study investigates the willingness of people
The construction of interfacial engineered heterojunctions is an effective strategy to broaden the optical response and facilitate charge separation. Herein, a novel 0D/1D Ag2S/Sb2S3 heterojunction is prepared by in-situ growth of Ag2S quantum dots on Sb2S3 nanorods using a simple hydrothermal approach. The 10% Ag2S/Sb2S3 (10AS) heterojunction exhibited efficient CO2 photoreduction activity with a
OBJECTIVES: Our aim was to derive, based on the SWEDEHEART registry, and validate, using the Western Denmark Heart registry, a patient-oriented risk score, the SweDen score, which could calculate the risk of 1-year mortality following a myocardial infarction (MI).METHODS: The factors included in the SweDen score were age, sex, smoking, diabetes, heart failure and statin use. These were chosen a pr
Background: Mutations in BRCA2 cause a higher risk of early-onset aggressive prostate cancer (PrCa). The IMPACT study is evaluating targeted PrCa screening using prostate-specific-antigen (PSA) in men with germline BRCA1/2 mutations. Objective: To report the utility of PSA screening, PrCa incidence, positive predictive value of PSA, biopsy, and tumour characteristics after 3 yr of screening, by BR
This paper develops a model based on the concept of Positive Mathematical Programming (PMP) that is useful for ex-ante analyses of how policy measures affect commercial fisheries. PMP models are frequently used in agriculture, but rarely for analyzing fisheries. Fisheries often face a large set of constraints such as effort regulations and catch quotas of which some might be binding and others not
Standing wave ambient pressure photoemission spectroscopy (SWAPPS) is a promising method to investigate chemical and potential gradients across solid-vapor and solid-liquid interfaces under close-to-realistic environmental conditions, far away from high vacuum. Until now, these investigations have been performed only near room temperature, but for a wide range of interfacial processes, chief among
This thesis addresses the corporate sustainability process and different tools to assist the process of generating corporate strategies towards sustainability in the energy sector. The focus of the research was in backcasting approaches. The main outcome of the work is a framework for corporate sustainability for the energy sector. The framework is constructed around a three step strategic plannin
Aiming to start a constructive debate,“A tour to sustainability?” examines the preparedness of the tour operating sector to undertake the challenges of sustainable tourism. Drivers and barriers for acknowledging operators’ share of impacts and consequently their responsibilities for actions are presented and analysed further. The influential potential of tour operators in tourism industry is defin
