De senaste århundraden har vår förståelse för världen runt omkring oss förbättrats avsevärt. Grundpelaren i att bedriva det vetenskapliga arbete som har lett fram till detta är att kunna utföra olika experiment vars resultat kan falsifiera olika teorier om de inte stämmer överens med observationerna. Allt eftersom de experimentella delarna av fysiken har fått möjligheten att göra noggrannare och nAfter the Higgs boson’s discovery precision searches for Beyond the Standard Model physics has become a new frontier in fundamental physics research. In extensions to the Standard Model, large combinatorics arising due to the many possibly involved particles in Feynman diagrams stands in the way of performing precision calculations of what such extensions predict. This work investigates the feasib

Purpose: Incisional hernia (IH) after open liver surgery is a well-recognized complication. The clinical importance of IH detected on computed tomography in terms of objective abdominal wall discomfort and impairment of quality of life (QoL) is less well known. Methods: Patients who underwent curative surgery for colorectal liver metastases between 2010 and 2015 at a single center and were alive i

In this editorial, we discuss why disclosure of many aspects commonly seen in positionality statements may be problematic given the cultural and legal context surrounding personal information in Europe, and the unequal distribution of required bravery, experienced burdens and barriers. We summarize current norms and problems with requiring labels, and suggest that, rather than disclosing identity

In this paper, the factors affecting flame extension under curved ceilings are presented. An experimental campaign in reduced scale was carried out in Lund University’s Fire Lab using a propane gas burner and heptane pool fire in different positions and heat release rates within a curved ceiling setup. A flame recognition script was developed to identify the flame length in the videos taken for ea

The United Nations (UN) put out a questionnaire and request for public comment on a proposal to form an Independent International Scientific Panel on ArtificialIntelligence (AI), as well as a Global Dialogue on AI in the context of the Global Digital Compact. The questionnaire was sent out in late 2024, and the following brief report forms the response submitted by the AI Policy Lab at Umeå Univer

JavaDL ArtifactJavaDL is a language and toolchain for analyzing Java at the source level. JavaDL is based on MetaDL, a variant of Datalog that adds syntactic pattern matching, here specialized to pattern matching on Java.

Hydrogen-based steelmaking using green hydrogen can achieve above 95 % CO2 emission reductions. Low-cost renewable electricity is a prerequisite and research has found that access to renewable energy resources could pull energy-intensive industry to new locations, the “renewables pull”-effect. However, previous studies on hydrogen-based steel differ on key assumptions and analyse a wide range of e

Artificial intelligence (AI) has rapidly emerged as a transformative technology across various disciplines. However, its widespread adoption is accompanied by numerous myths, which are fueled by limited public understanding and can significantly shape how individuals perceive and interact with AI, often leading to negative consequences such as misunderstanding, fear, or resistance. Despite the imp

Extreme conditions caused by climate change and other crises call for enhancing the resilience of buildings and urban energy systems. This paper investigates the role of collaborative decision-making to improve the performance of single buildings and the unified whole in the form of a cohesive cluster of energy consumers to enhance resilience. CIRLEM, the previously developed energy management app

Numerous studies have been carried out in recent years on the use of virtual reality (VR) technologies and environments in education. On the other hand, many researchers have drawn attention to the inadequacy of studies that deal with the education process in virtual reality environments from a broad perspective. In this research, the process of designing, developing, and testing an educational vi

The application of Agent-Based Modeling and Simulation (ABMS) has few established guidelines and often suffers from insufficient model documentation. We assess the prevalence of best practices associated with different types of model documentation in light of the European Union’s AI Act (AI Act). Our analysis reveals that best practices are often implemented together but ultimately reinforce the p

We introduce the point process [Formula presented] where Zn is the normalization constant. This point process is attractive: it involves n dependent, uniformly distributed random variables on the unit circle that attract each other. (For comparison, the well-studied CβE involves n uniformly distributed random variables on the unit circle that repel each other.) We consider linear statistics of the

Background & aims: We have previously reported that the serum levels of gut-derived tryptophan metabolite indole-3-propionic acid (IPA) are lower in individuals with liver fibrosis. Now, we explored the transcriptome and DNA methylome associated with serum IPA levels in human liver from obese individuals together with IPA effects on shifting the hepatic stellate cell (HSC) phenotype to inactiv

Slow sand filters (SSFs) for drinking water production are habitats for diverse microbes from multiple domains of life, which are integral to the ability of SSFs to purify water. While cultivation-independent analyses of the prokaryotic communities of SSFs have provided valuable insights, little attention has been paid to fungi inhabiting SSFs. This study characterized the fungal communities in th

Greywater, which comes from household sources such as showers, laundry, and dishwashing, is typically less polluted than toilet wastewater and can be treated and reused. In Helsingborg, Sweden, the RecoLab collects and treats greywater from Oceanhamnen separately as part of a source-separated wastewater system. However, the system has experienced is-sues with filamentous bacteria overgrowth, raisi

Introduction: PARP15 belongs to the PARP family, which carries out ADP-ribosylation, a post- translational modification involved in DNA repair. Finding selective inhibitors can help discover more of the role PARP15 plays in our body. Background: Inhibitors of other PARP family members, such as PARP1, have been studied because of their role in cancer processes. However, PARP15 remains poorly charac

I samband med att ett intrångsmål prövas är det inte ovanligt att svaranden invänder att den immaterialrätt som intrånget avser är ogiltig. Ett ogiltighetsförsvar kan vara ett effektivt sätt för den påstådda intrångsgöraren att retroaktivt beröva käranden den rättighet som ligger till grund för intrångstalan och, om talan ogillas, undvika ansvar. När det gäller immaterialrättsliga tvister som prIn the context of an infringement action, it is not uncommon for the defendant to object that the intellectual property right in question is invalid. An invalidity defence may be an effective strategy for the alleged infringer to retroactively deprive the right on which the plaintiff's infringement action is based and, if the court dismisses the action, thereby avoid liability. In the context

Fri rörlighet för varor och konsumentskydd utgör två centrala intressen inom EU. Emellertid är det inte ovanligt att det uppstår en konflikt mellan de två intressena. Ett exempel på en sådan konflikt är regleringen av produktmärkning på mottagarlandets språk. Regleringen av produktmärkning på mottagarlandets språk syftar främst till att skydda konsumenter genom att se till att information om en The free movement of goods and consumer protection are two key interests within the EU. However, it is not unusual that a conflict occurs between the two interests. An example of such a conflict is the regulation of product labelling in the language of the recipient country. The regulation of product labelling in the language of the recipient country primarily aims to protect consumers by ensuri

Hanteringen av barn som begår brott är ett allt mer omdiskuterat ämne, särskilt mot bakgrund av den markanta ökningen av grova våldsbrott som begås av barn under 18 år. Samtidigt som svensk gällande rätt traditionellt präglats av principen att barn inte ska fängslas, har allt fler unga frihetsberövats. Detta aktualiserar både rättsliga och etiska frågor om hur samhället bör agera när barn begår alThe treatment of children who commit crimes is an increasingly debated topic, particularly in light of a marked increase in serious violent crimes com- mitted by children under 18. While Swedish law has traditionally been char- acterized by the principle that children should not be imprisoned, the reality is that more and more young people are being deprived of their liberty. This raises both lega
