A new species of Purpureocillium (Ophiocordycipitaceae) fungus parasitizing trapdoor spiders in Brazil’s Atlantic Forest and its associated microbiome revealed through in situ “taxogenomics”

Our planet is inhabited by an estimated 2.5 million species of fungi, of which fewer than 10% have been scientifically described. Some of the most understudied yet remarkable fungal species are those capable of parasitizing arthropods, notably insects and spiders. Here, we explore the hidden diversity of a spider-attacking (araneopathogenic) fungus and its associated microbiome in one of the world

Artificial intelligence approaches for mapping the nexus of biodiversity, climate change and human society

We face closely intertwined crises related to biodiversity, climate change, global health andinequality. Unfortunately, the knowledge that could help overcome these existential crises isscattered across millions of scientific articles, reports, policy documents, databases, andindividual datasets, far exceeding human processing capabilities. This hinders evidence-basedresearch, innovation and polic

Loss of nidogen-1 causes lung basement membrane defects and increased metastasis

Metastasis is the most common cause of cancer patient deaths. It is a complex process strongly influenced by the extracellular matrix (ECM). A mass spectrometry analysis comparing ECM proteins from healthy mouse lungs versus metastatic lungs has previously been performed, and the basement membrane (BM) component nidogen-1 has been identified to be one of the most downregulated ECM proteins in meta

Knowledge Production About Women’s Experiences of Conflict. A Critical Analysis of the WPS Agenda

The Nordic states have played a central role in the production of knowledge within the Women, Peace and Security (WPS) agenda. Through a strong research tradition in peace and conflict studies, extensive policy development, and significant international engagement, the Nordic region has contributed to both the theoretical and practical advancement of the agenda. In this article, we examine the WPS

Affective construal in deictic gestures as evidence for awareness in choice making

What is the role of deictic gestures in expressing affective valence, and can such gestures serve as an indicator of awareness in choice making? To examine this, we analyzed participants’ deictic gestures toward preferred and non-preferred picture alternatives in an experimental choice justification task. The task involved manipulation: in some trials, participants were presented with the rejected

Image enhancements by CLAHE and gamma correction do not improve diagnostic accuracy in teledermoscopy: a retrospective cohort study

Teledermoscopy (TDS) offers an efficient alternative to face-to-face assessment of suspicious skin lesions. Although diagnostic accuracy in TDS is relatively high, further improvement is desirable to reduce the risk of overlooked skin cancers and unnecessary interventions of benign lesions. Image enhancement (IE), i.e. digital modification of different parameters of an image, may potentially impro

Integrated life cycle assessment (ILCA) approach to daylighting renovation of a sports hall considering light quality, environmental and financial aspects

Purpose – This paper concerns an integrated life cycle assessment (ILCA) comparing daylighting retrofit solutions for an existing sports hall, currently relying only on electric lighting. Daylight quality, environmental impact and financial aspects are generally independently considered, leading to suboptimal decisions when all aspects are considered together. By taking the sports hall as an examp

“Det har blivit så vanligt för ungdomarna att dom inte reflekterar över att det är en form av våld”

The digitalisation of adolescents’ everyday lives has created new contexts in which intimate partner violence can occur. Digital intimate partner violence includes controlling, monitoring, and harassing behaviours carried out through digital tools such as social media, messaging applications, and location-sharing services. These behaviours are often normalised among young people, which makes the v

Bio-Compositional and Microstructural Changes in Rabbit Knee Collateral Ligaments Eight Weeks After Anterior Cruciate Ligament Transection

Injury to the anterior cruciate ligament (ACL) is common in young, active individuals. It has the potential to lead to post-traumatic osteoarthritis. However, the effects of ACL injury on the bio-composition and microstructure of the knee's collateral ligaments have been poorly explored. In this study, Fourier transform infrared (FTIR) imaging and quantitative polarized light microscopy (qPLM) wer

Acquisition Geometry vs Radiation Dose in Digital Breast Tomosynthesis : Design Considerations for Optimizing the Reconstruction Quality Through Denoising

In the last decade, breast cancer diagnosis has seen the widespread application of digital breast tomosynthesis (DBT) in screening programs. DBT involves the X-ray tube traversing along an arc trajectory parallel to the patient’s chest wall, acquiring multiple low-dose mammograms from various angles. Reconstruction algorithms process these projection views to generate a stack of slices forming a p

The Growth, Inequality, and Poverty Nexus : Lessons from Long-term Trends in Tanzania, 1961–2017

This paper analyses the growth-inequality-poverty nexus in Tanzania. We provide a unique long-term study covering six decades of Tanzanian independence and disentangle the competing narratives concerning growth, inequality, and poverty in the country. We do this by carefully assessing the existing–and at times contradictory–data on growth, inequality, and poverty and by introducing the inequality

Propagating Model Uncertainty through Filtering-based Probabilistic Numerical ODE Solvers

Filtering-based probabilistic numerical solvers for ordinary differential equations (ODEs), also known as ODE filters, have been established as efficient methods for quantifying numerical uncertainty in the solution of ODEs. In practical applications, however, the underlying dynamical system often contains uncertain parameters, requiring the propagation of this model uncertainty to the ODE solutio

Advancing Food By-Product Valorization: Membrane Technologies for Sustainable Protein Recovery

Membrane technology plays a crucial role in food by-product valorization, especially in protein recovery. Initially applied to whey protein extraction from cheese production, it enabled the concentration and purification of whey, leading to the production of protein concentrates and isolates. This success was extended to other animal proteins like blood plasma, fish proteins, and albumen.With a gr

A Central Limit Theorem and Exponential Correlation Decay for the Coulomb Chain

We study the Coulomb chain where particles are restricted to one dimension and experience three-dimensional Coulomb interactions with their nearest and next-to-nearest neighbours. The distances between consecutive particles are treated as random variables. It is shown that the correlation between clusters of consecutive variables decay exponentially with the number of variables separating them. Th
