The ongoing war in Ukraine is associated with unprecedented radiological threats to the public in Ukraine and the neighboring countries. This calls for fundamental revision of the preparedness plans and established approaches to radiological monitoring of the populations affected by potential radiological emergencies. Dosimetric information will be needed for triage of victims and support to decis
Males that behave violently to achieve social and reproductive objectives are a widespread phenomenon among mammals, as well as humans. Because this kind of behaviour can be socially very disruptive, its continued survival in human populations, in particular, remains a puzzle. We use historical data on the pedigrees of medieval Icelandic Vikings to test the hypothesis that males who killed had hig
In this study, high pressure synchrotron powder X-ray diffraction is used to investigate the compression of two high pressure polymorphs of CrSb2. The first is the CuAl2-type polymorph with an eight-fold coordinated Cr, which can be quenched to ambient conditions from high-pressure high-temperature conditions. The second is the recently discovered MoP2-type polymorph, which is induced by compressi
Quinones are organic molecules that facilitate electron-transfer reactions in terrestrial environments. The reduced forms, hydroquinones, are powerful reductants that can trigger non-enzymatic radical-based decomposition of organic matter and contaminants by simultaneous reduction of iron and oxygen. Iron oxides often occur as coatings on other minerals, thus our study investigated the reactions b
This paper addresses the problem of consensus on SO(3) for networks of uncalibrated cameras. Under the assumption of a pinhole camera model, we prove convergence to the consensus manifold for two types of kinematic control laws, when only conjugate rotation matrices KRK -1 are available among the agents. In these conjugate rotations, the rotation matrices are distorted by the (unknown) intrinsic p
Businesses across different areas of interest are increasingly depending on data, particularly for machine learning (ML) applications. To ensure data provisioning, inter-organizational data sharing is proposed, e.g. in the form of data ecosystems. The aim of this study was to perform an exploratory investigation into the data sharing practices that exist in business-to-business (B2B) and business-
Recent self-reported and cross-sectional survey evidence documents high levels of mental health problems among PhD students. We study the impact of PhD studies on mental health care uptake using Swedish administrative records of prescriptions for psychiatric medication for the full population of PhD students. First, we provide descriptive evidence that PhD students collect psychiatric medication a
Understanding how momentum anisotropies arise in small collision systems is important for a quantitative understanding of collectivity in terms of QCD dynamics in small and large collision systems. In this letter we present results for small collision systems from the newly developed parton cascade ALPACA, which faithfully encodes the AMY effective kinetic theory. ALPACA reproduces quantitatively
Economic research on gender gaps in preferences and economic outcomes has focused on variation with respect to sex—a binary classification as either a “man”or “woman.” We validate a novel and simple measure of self-reported continuousgender identity (CGI) and explore whether gender identity correlates with variationin economic decisions and outcomes beyond the relationship with binary sex.We use f
Identifying key molecular pathways and genes involved in the response to urban pollutants is an important step in furthering our understanding of the impact of urbanisation on wildlife. The expansion of urban habitats and the associated human-introduced environmental changes are considered a global threat to the health and persistence of humans and wildlife. The present study experimentally invest
Objectives: To examine the risk of fractures in a cohort of patients with newly diagnosed rheumatoid arthritis (RA), compared to the background population, and predictors of fractures detectable early in RA. Methods: An inception cohort of patients with RA (N = 233; 164 women/69 men, recruited 1995–2005) was evaluated according to a structured program, including repeated clinical assessments and m
This paper is a study of the implementations of two new working methods, systems construction and incentive contracts, in Swedish State building construction around 1970 with an analysis of the implication of such implementations on the organization of the building industry. Specifically, the study is focusing on the role of the architect in the building process of the National Board of Public Bui
Significant progress has been made in elucidating genetic risk factors influencing Type 1 diabetes (T1D); however, features other than genetic variants that initiate and/or accelerate islet autoimmunity that lead to the development of clinical T1D remain largely unknown. We hypothesized that genetic and environmental risk factors can both contribute to T1D through dynamic alterations of molecular
Both straight and curved carbon fibers are widely used in various commercial gas diffusion layer (GDL) fabrications. The effect of the different carbon fiber curvatures on two-phase flow dynamics within the cathode GDLs of proton exchange membrane fuel cells remains unclear. In this study, we investigate liquid transport in three types of GDLs with varying fiber curvatures using the two-phase volu
The production, reading and correcting of article proofs is a highly important part of scholarly publishing, and the proof of an article is the only place where researcher, journal production team and publisher come together, directly or indirectly. Yet, the proof process is rarely examined or discussed, and scholars seem to regard it as something separated from the research process.

When coupled to different applications, a polymer electrolyte fuel cell (PEFC) work at a different operating temperature. In this study, the internal resistance of a PEFC is evaluated by using Electrochemical Impedance Spectroscopy (EIS) at moderate low current density, i.e., 0.5 A/cm2, in the range of 40 – 80°C. The evaluation is carried out considering frequencies between 10kHz and 0.1Hz. An equ
Mycket forskarmöda har ägnats åt den stora reduktionen i början av 1680-talet, då den svenska adelns förläningar drogs in till kronan och maktbalansen skiftade till den enväldige kungens fördel. Denna forskning har framför allt behandlat den politiska och ekonomiska utvecklingen, ofta ur ett elitperspektiv. Andra gruppers agerande och levda verklighet har sällan blivit belysta, vilket inte minst gA large body of scholarly work has been dedicated to the Swedish reduction in the early 1680s when fiefs granted to the nobility were revoked as the crown strengthened its position. However, this research has focused on political and economic developments from an elite perspective. Insufficient attention has been paid to the actions and lived realities of other groups, not least the servants of th
