Explaining the evolutionary origin and maintenance of color polymorphisms is a major challenge in evolutionary biology. Such polymorphisms are commonly thought to reflect the existence of alternative behavioral or life-history strategies under negative frequency-dependent selection. The European common wall lizard Podarcis muralis exhibits a striking ventral color polymorphism that has been intens

The origin of eukaryotes represents an unresolved puzzle in evolutionary biology. Current research suggests that eukaryotes evolved from a merger between a host of archaeal descent and an alphaproteobacterial endosymbiont. The discovery of the Asgard archaea, a proposed archaeal superphylum that includes Lokiarchaeota, Thorarchaeota, Odinarchaeota and Heimdallarchaeota suggested to comprise the cl

Proactive identification and characterization of hazards attributable to chemicals are central aspects of risk assessments. Current legislations and trends in predictive toxicology advocate a transition from in vivo methods to nonanimal alternatives. For skin sensitization assessment, several OECD validated alternatives exist for hazard identification, but nonanimal methods capable of accurately c

Background: User involvement is a requirement of most research funders. There is a growing body of literature exploring the benefits and challenges of user involvement in research, but such studies are scarce in the field of aging and health. Moreover, the majority of such research is qualitative, which limits the generalizability of results. The UserAge panel study will be instrumental in expandi

This paper presents a search for new heavy particles decaying into a pair of top quarks using 139 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of s = 13 TeV with the ATLAS detector at the Large Hadron Collider. The search is performed using events consistent with pair production of high-transverse-momentum top quarks and their subsequent decays into the fully hadronic f

Initiation of celiac disease is triggered in the gastrointestinal tract by transglutaminase 2 (TG2) assisted deamidation of gluten peptides. Deamidation is a side-reaction to transamidation and occurs if primary amines are absent. In contrast to deamidation, transamidation does not trigger an immune response. The aim of the study was to identify a suitable food additive that interacts with TG2 bin

Processing of lignocellulosic biomass is complex due to the heterogeneity of the substrate, but also due to lengthy unit operations, which complicates process control including for enzymatic saccharification. Methods for predicting enzymatic saccharification yield based on the properties of the pretreated biomass would be advantageous to process optimization and control. Biomass-water interaction

The demand for better methods for condition control and monitoring of embankment dams will increase in a near future as a result of expected more extreme weather situations. Furthermore the availability demand on hydropower will increase as a result of switching from fossil fuels to wind and solar power, in some countries in combination with decommissioning of nuclear power. Temperature monitoring

Spatial downscaling is an effective way to obtain precipitation with sufficient spatial details. The performance of downscaling is typically determined by the empirical statistical relationships between precipitation and the used auxiliary variables. In this study, we conducted a comprehensive comparison of five empirical statistical methods for spatial downscaling of GPM IMERG V06B monthly and an

The COVID-19 pandemic has raised awareness of the urgent need to improve the design of health systems, as well as the practical implementation of new strategies and technical solutions to better prepare for future pandemics. These preparations must also consider harms secondary to the pandemic, including the resulting effects on antimicrobial resistance (AMR). While drug-resistant infections pose

The aesthetic outcome is crucial in a breast reconstruction. Our aim was to evaluate the intra- and interrater reliability of an aesthetic outcome assessment scale with digital photos of breast reconstructions in two-dimensional (2D) and three-dimensional (3D) format. Thirty-three women with delayed breast reconstructions, consecutively participating in a five-year follow-up between November 2019

OBJECTIVES: Sequential Organ Failure Assessment score is the basis of the Sepsis-3 criteria and requires arterial blood gas analysis to assess respiratory function. Peripheral oxygen saturation is a noninvasive alternative but is not included in neither Sequential Organ Failure Assessment score nor Sepsis-3. We aimed to assess the association between worst peripheral oxygen saturation during onset

This article illuminates (inter)actions and group dynamics of adult volunteers in programs for bereaved children and parents. A focus group interview with seven volunteers in Swedish was conducted. A latent, thematic analysis was conducted, inspired by Braun and Clarke, and Goffman. Two themes were constructed: Personal despair as a motivation for establishing and consolidating voluntary involveme

Introduction: This study examined the emotional impact that parents experience when confronted with an increased genetic risk of type 1 diabetes (T1D) in their child. Population-based screening of neonates for genetic risk of chronic disease carries the risk of increased emotional burden for parents. Methods: Information was collected using a well-being questionnaire for parents of infants identif

The implications of professionalization of civil society organizations have seldom been explored in relation to the governance structure of organizations’ and leaders’ different terms of engagement. This study draws on a survey targeting leaders of Swedish welfare-oriented civil society organizations (N. 140) and compares the motives for engagement and leadership ideals of two groups of leaders: b

Why and how new migration routes emerge remain fundamental questions in ecology, particularly in the context of current global changes. In its early stages, when few individuals are involved, the evolution of new migration routes can be easily confused with vagrancy, i.e. the occurrence of individuals outside their regular breeding, non-breeding or migratory distribution ranges. Yet, vagrancy can

INTRODUCTION Women and their families are often excluded from reproductive decisionmaking processes in postnatal care, and do not know which choices they have. Shared decision-making is a critical but challenging component of maternity care quality. The aim was to explore women's experience of the decision-making process about early return from hospital with home-based postnatal midwifery care. ME
