X-ray phase contrast imaging (X-PCI) is a powerful technique for high-resolution, three-dimensional imaging of soft tissue samples in a non-destructive manner. In this technical report, we assess the quality of standard histopathological techniques performed on formalin-fixed, paraffin-embedded (FFPE) human tissue samples that have been irradiated with different doses of X-rays in the context of a
Systematic evaluations are vital to support learning and enhance performance in a crisis response. There are quantitative methods available today for evaluating crisis response management (CRM), but there are limiting factors negatively affecting their potential; They often involve techniques difficult to implement in real events, lack reliability testing, provide outcomes questionable from a lear
Over the last thirty years, suggestions for how to develop defence capability have developed rapidly. However, supporting theory and structured concept development lag behind. Despite this imbalance, countries need to continuously spend resources on defence development. This study identifies central challenges in relation to the scientific perspectives and approaches needed to support the developm
Background and aims: Gestational diabetes is more common in many first-generation immigrant women in Europe and other Western countries. Less is known about second-generation immigrant women; such knowledge is needed to understand generational influences on diabetes risk. We aimed to study second-generation immigrant women regarding the presence of all types of diabetes during pregnancy. Methods a
Background: Chronic lymphocytic leukemia (CLL) has been a good model system to understand the functional role of 5-methylcytosine (5-mC) in cancer progression. More recently, an oxidized form of 5-mC, 5-hydroxymethylcytosine (5-hmC) has gained lot of attention as a regulatory epigenetic modification with prognostic and diagnostic implications for several cancers. However, there is no global study
The inclusive top-quark pair (tt¯) production cross-section σtt¯ is measured in proton–proton collisions at a centre-of-mass energy s = 5.02 TeV, using 257 pb−1 of data collected in 2017 by the ATLAS experiment at the LHC. The tt¯ cross-section is measured in both the dilepton and single-lepton final states of the tt¯ system and then combined. The combination of the two measurements yields σtt¯=67
Gaia Data Release 3 provides novel flux-calibrated low-resolution spectrophotometry for '220 million sources in the wavelength range 330 nm ≤ λ ≤ 1050 nm (XP spectra). Synthetic photometry directly tied to a flux in physical units can be obtained from these spectra for any passband fully enclosed in this wavelength range. We describe how synthetic photometry can be obtained from XP spectra, illust
Dimensionality reduction is an Exploratory Data Analysis (EDA) approach allowing for fast visualization of high-dimensional data and the possibility of discovering hidden systematic patterns within a data set. While linear dimensionality reduction techniques, such as Principal Component Analysis (PCA), are considered the golden standard in many areas of data science, they seem to be inadequate for
This work is focused on the modelling of experimental behaviour of a bone-shape sample made of aluminium alloy AW5083 under tension. This behaviour involves propagating instabilities, namely Lueders bands and the Portevin–Le Chatelier effect. A series of experiments was performed at room temperature for three loading rates, showing the instabilities and failure. In the paper a large strain thermov
Friction characteristics and wear of sheet-bulk metal forming tools featuring microstructured surfaces are simulated on the mesoscale. Computational homogenisation is used for surface cut-outs on which the structures are geometrically resolved and where friction laws model lower scale roughness. Two approaches are presented for the modelling of wear. A dissipation based Archard model is implemente
Background and objective Low-density computed tomography (LDCT) improved early lung cancer diagnosis but introduces an excess of false-positive pulmonary nodules data. Hence, accurate diagnosis of early-stage lung cancer remains challenging. The purpose of the study was to assess the feasibility of using circulating tumour cells (CTCs) to differentiate malignant from benign pulmonary nodules. Mate
This study explores the potential benefits of combining a wave-shaped piston geometry with post injection strategy in diesel engines. The wave piston design features evenly spaced protrusions around the piston bowl, which improve fuel-air mixing and combustion efficiency. The ‘waves’ direct the flames towards the bowl center, recirculating them and utilizing the momentum in the flame jets for more
Circular economy (CE) has been of utmost interest in the industry and research community in the preceding years. However, CE is still a nascent research field in the built environment context. As technological advances within CE are slowing, the incorporation of business models into the concept is deemed important to achieve the necessary transition. Circular business models within the built envir

Nitrogenase is the only enzyme that can cleave the strong triple bond in N2, making nitrogen available for biological life. There are three isozymes of nitrogenase, differing in the composition of the active site, viz., Mo, V, and Fe-nitrogenase. Recently, the first crystal structure of Fe-nitrogenase was presented. We have performed the first combined quantum mechanical and molecular mechanical (

The construction industry has a great impact on the environment but there is a great potential for improvements. In the era of climate change, sustainable construction methods and ecological solutions are required to improve energyefficiency, and to decrease the environmental impact of housing development. Circular Economy is considered a feasible solution to global sustainability issues and relat
This article analyses the competence shift in EU competition law, with a particular focus on the digital era and the EU’s institutional dimension. As will be argued, the latter is expanding by means of new legislation in the Digital Single Market. Particularly Article 114 TFEU is employed as a legal base for this purpose, which essentially harmonises and pre-empts Member States’ action in this are
While the role of grandparents has increasingly been explored, the position of being a grandchild is under-researched. Recognising the active role of children in intergenerational care relationships, we analyse narratives of being a grandchild in Sweden in the 1940s–1950s, the 1970s–1980s, and today. Interviews with 63 participants of both genders show how conditions for care-doings change in resp
En studie av hur föreställningsförmågan, det inre seendet, uppmuntrades av några Vadstena-predikanter på 1400-talet. Framför allt tar artikeln upp en predikan över den Apostoliska trosbekännelsen, vilken kopplas samman med ädelstenarna i den Heliga Stadens grundmurar i Uppenbarelseboken. Artikelförfattaren gör en koppling till ett unikt smycke, det s k Motalaspännet.
