This thesis encompasses an introductory part and five papers related to developing techniques and phantoms required for the further growth of photoacoustic imaging (PAI). In PAI, images are created by detecting acoustic waves followed by the absorption of laser light, enabling high spatial resolution while maintaining high optical contrast. Due to the distinct absorption patterns of various chromo
To further understand the inter-relationship of the familial transmission of major depression (MD) and alcohol use disorder (AUD), we examine, via a multivariable Cox proportional hazards model, risks for AUD and MD in 1,244,516 individuals born in Sweden from 1970 to 1990 to intact mother-father pairs as a function of parental diagnoses of MD and/or AUD. Across the nine possible mating types, we
Some things hold value in a way that makes them superior to others, regardless of how much of the lesser values are involved. Philosophers have often found this idea of persistent betterness to be puzzling. In this paper, we argue that superiority belongs to a broader class of persistent value relations, including stubborn varieties of equality and parity, each of which will be exemplified and ana
Humaniora är ett viktigt – men ibland underskattat – vetenskapsområde som behövs för att utbilda studenter för en komplex yrkesvardag och för att möta aktuella samhällsutmaningar. Humanistisk kompetens ger förmåga att tolka, förstå och sätta kunskap i ett kulturellt, historiskt och samhälleligt sammanhang. Humaniora hjälper oss att navigera i komplexa frågor som inte enbart handlar om effektivitet
In the software industry, the drive to add new features often overshadows the need to improve existing code. Large Language Models (LLMs) offer a new approach to improving codebases at an unprecedented scale through AI-assisted refactoring. However, LLMs come with inherent risks such as braking changes and the introduction of security vulnerabilities. We advocate for encapsulating the interaction
Maintainable source code is essential for sustainable development. Yet, many studies show that maintainability often receives less attention than it deserves. We argue that requirements engineering can help close this gap by fostering discussions and setting appropriate targets in a responsible manner. In this preliminary work, we explore industry practices related to requirements engineering for
The introduction to this special issue argues that International Relations (IR) needs to give greater consideration to the existential and psychological implications of the accelerating climate crisis. Starting from debates about the disciplinary suitability of IR to meaningfully tackle an issue as all-encompassing as climate change, this introduction gives a short overview of how the problem of c
The remarkable advances in AI and Large Language Models (LLMs) have enabled machines to write code, accelerating the growth of software systems. However, the bottleneck in software development is not writing code but understanding it; program understanding is the dominant activity, consuming approximately 70% of developers' time. This implies that improving existing code to make it easier to under
Inledning till recensionsavdelningen i Historielärarnas Förenings Årsskrift 2025, vilken jag har varit redaktör för.
With the aim of isolating immunomodulatory compounds from the n-butanol extract of Boehmeria nivea leaves, nine megastigmane compounds were identified. Among these, the structure of the new compound 1, namely, “boehmegaside A”, was established using NMR and HR-ESI-MS, and its absolute configurations were established through ECD calculations and DP4+ analysis using DFT-NMR chemical shift calculatio
The relationship between requirements engineering and testing has been a key interest throughout my research career. It cannot be that requirements engineers are from Omicron Persei 7 and testers from Omicron Persei 9—we all live on the same planet. I’m happy to co-author this column with a former collaborator from a test automation EU project, now a manager at Ericsson. With this issue’s focus on
Background: Comorbid conditions and breathlessness are associated with poor outcomes in chronic obstructive pulmonary disease (COPD). We evaluated the associations of comorbid heart disease and depression/anxiety with breathlessness in daily life among people with COPD. Methods: Cross-sectional analysis from the PRAXIS cohort in central Sweden. Data on patient characteristics and the modified Medi
Background: Carry Life UF is a novel peritoneal dialysis (PD) technology for improved fluid management using steady concentration PD (SCPD). The Carry Life UF treatment starts with a manual peritoneal fill of 1.36% glucose PD fluid, followed by a 5-hour treatment where small amounts of glucose are continuously added to maintain a stable intraperitoneal glucose concentration. A recent in-center cli
This column summarizes a panel discussion given by REFSQ 202 held in Barcelona on responsibility. Given the mediator role of our field, what other soft- ware engineering discipline could be a better fit for responsible engineering? And this will just keep getting more important as the influence of technology on society increases.
The study examines trends in part-time employment among school students (15–20 years old) in Sweden. Using data from the Swedish Labor Force Survey (2006–2019) and population-based registries, the article analyzes developments in employment rates and work patterns. The results indicate a rapid increase in part-time work, particularly in the hospitality sector, which underscores how young student-w
Huntington’s disease is a progressive, untreatable neurodegenerative disorder caused by a mutation in the Huntingtin gene. Next to neurodegeneration, altered immune activation is involved in disease progression. Since central nervous system inflammation and dysfunction of immune cells are recognized as driving characteristics, immunomodulation might represent an additional therapeutic strategy. Sh
This article examines the formation of teenage students as workers through their participation in low-status service jobs, building on Weeks’ theorization of the contemporary work ethic. Based on 40 interviews with working teenagers in Sweden, the analysis explores how they use narratives of working to ‘gain experience’ and ‘earn extra money’ in response to the cultural imperative of constructing
Hundreds of active learning assignments are reported in the political education literature. However, the adaptability of these assignments to new courses can be limited by different learning outcomes, course themes, or institutional contexts. To assist educators in developing assignments that align with their teaching needs, this study introduces the concept of element design. Element design refer
Cluster superlattice membranes constitute a novel 2D material, comprising a cluster superlattice sandwiched between a graphene support and an amorphous carbon embedding matrix. They offer a platform for investigating phenomena at the few atom to small cluster level with lateral averaging techniques. The amorphous carbon matrix provides mechanical and thermal stability to the cluster array, but alt
