Octylisothiazolinone—A New Sensitizer in Over-Ear Headphones

Background: Allergic contact dermatitis (ACD) caused by isothiazolinones is a growing concern, particularly in consumer products. Octylisothiazolinone (OIT) is a potent sensitiser and commonly used as a preservative in rubbers, plastics and coatings, including those found in headphones. Despite increasing regulations on isothiazolinones in cosmetics, their presence in wearable devices remains unde

On Minimax Optimal Dual Control for Fully Actuated Systems

A multi-variable adaptive controller is derived as the explicit solution to a minimax dynamic game. The minimizing player selects the control action as a function of past state measurements and inputs. The maximizing player selects disturbances and model parameters for the underlying linear time-invariant dynamics. This leads to a Bellman equation that can be solved explicitly for the case with un

Smart City Governance – AI Ethics in a Spatial Context : Selected Essays from 2024/2025

This brief anthology begins with a basic outline of the interdisciplinary course Smart City Governance – AI Ethics in a Spatial Context, given at LTH, Lund University. Three selected student essays from the class of 2024/2025 then follow. These demonstrate the topics possible to analyse when combining engineering students from programmes on data, ICT, architecture, and land surveying with students

A THEORETICAL STUDY OF THE OBJECTIVE-FUNCTIONAL FOR JOINT EIGEN-DECOMPOSITION OF MATRICES

The problem of approximate joint eigen-decomposition of a collection of matrices arises in a number of diverse engineering and signal processing problems. This problem is usually cast as an optimization problem, and it is the main goal of this publication to provide a theoretical study of the corresponding objective-functional. As our main result, we prove that this functional tends to infinity in

Fossil capital at 10 : Andreas Malm on capitalism, energy, and resistance

With the publication of Fossil Capital in 2016, Andreas Malm reshaped how scholars understand the relationship between capitalism and fossil fuels. Energy humanities scholars Caleb Wellum and Imre Szeman interviewed Malm in November 2024 about the arguments and impact of Fossil Capital, the development of his thought in several subsequent books, and the shifting landscape of climate politics. At a

Due Diligence and Due Remedy? A Critical Evaluation of Human Rights Due Diligence in the UN Binding Treaty on Business and Human Rights: Lessons from Marikana and Comparative Case Studies.

The discourse on Business and Human Rights (BHR) has evolved substantially over the past two decades, particularly since the adoption of the UN Guiding Principles on Business and Human Rights (UNGPs) in 2011. While the UNGPs established the corporate responsibility to respect human rights through Human Rights Due Diligence (HRDD), their voluntary nature has resulted in fragmented implementation an

Two sides of the same green coin? A legal analysis of the concept of the (green) industrial competitiveness of the Union through the Net-Zero Industry Act

I den pågående kampen mot klimathotet har Europeiska unionen antagit en ledande roll för att fullfölja skiftet mot en grön ekonomi, bland annat genom att fokusera på att stärka konkurrenskraften avseende tillverkningen av netto-noll energiindustrin och säkra de nödvändiga råvarorna för denna omställning. För att möjliggöra detta presenterade den Europeiska kommissionen i mars 2023, i samband med pIn the global race against climate change, the answer of the European Union is the transition towards a green economy by focusing on strengthening the competitiveness of the net-zero technology industry and securing the necessary critical materials. To do so, the Union presented two legislative acts in the European Green Deal Industrial Plan in 2023, amongst which the Net-Zero Industry Act. While

Mapping the distribution of neurotransmitters to resting-state functional connectivity in Parkinson's disease

Dopamine and serotonin are two major monoamine neurotransmitters associated with Parkinson's disease (PD), but their spatial distribution and relationship to underlying functional brain architecture are not fully understood. We assessed 30 patients with PD at baseline using structural MRI, resting-state functional MRI (rs-fMRI), 11C-PE2I and 11C-DASB PET, along with comprehensive clinical evaluati

Higher music education as a site of public pedagogy : Identifying institutional change in the Nordic countries

This study explores how higher music education institutions position themselves in relation to wider social and political forces and the expanding professional responsibilities of musicians in increasingly complex Nordic societies, which in this study includes Finland, Sweden, Norway and Denmark. By asking how the political—including various local and global social-ecological values, relations and

Patterns of Caffeine Use in Adolescents and Their Association with Sleep Quality : A Latent Class Analysis

Background: Although there is substantial evidence of the negative impact of caffeine use on sleep quality, few studies focus specifically on adolescents’ patterns of use. This study aimed to identify patterns of caffeine use among adolescents and analyze their association with sleep quality. Method: A cross-sectional study was conducted in southern Sweden including 1,404 adolescents aged 15–17 (5

Thalassa : Transforming Symbolic PDEs into Tensor-Based Solvers Running on ML Accelerators

We introduce Thalassa, a framework designed to convert nonlinear systems of partial differential equations (PDEs) with a time-like component into tensor programs that solve these equations. These programs can run on GPUs as well as machine learning (ML) acceleration hardware, enabling scientific computing fields such as computational fluid dynamics, astrophysics, mechanics and biology to utilize a

Characteristics of short REM sleepers and long-term CPAP use in the RICCADSA cohort

Study objectives: The impact of rapid eye movement (REM) sleep duration on long-term adherence to continuous positive airway pressure (CPAP) therapy in patients with obstructive sleep apnea (OSA) is unclear. This study aimed to assess the characteristics of individuals with short REM sleep and investigate whether reduced REM sleep is associated with lower CPAP adherence over a two-year period in t

Bricks without straw: Using linked census data to estimate child mortality in the pre-registration era of the United States

We describe a method to estimate child mortality using linked IPUMS full-count census data for the decades following the 1850, 1860, 1870, 1900, 1910, 1920, and 1930 censuses. We compare the estimates to several external sources and conclude that the method represents a viable way to estimate and model child mortality at individual and aggregate levels over the course of the mortality transition.

Predictive Value of Plasma Biomarkers in Tau-PET Transitions

Objective: The objective of this study was to determine the predictive value of amyloid-positron emission tomography (PET) versus the plasma ratio of phosphorylated tau at threonine 217 (p-tau217) to non-phosphorylated tau217 (%p-tau217) for tau-PET transitions (T− to T+). The added value of combining plasma amyloid-β 42 and amyloid-β 40 (Aβ42/40) and %p-tau217 into an amyloid probability score (A
