Traditionally, traffic safety is expressed through the number of accidents (crashes) or people injured, since these are the most direct manifestations of an unsafe traffic environment. As we discuss in this chapter, such an approach has its limitations due to the low frequency of accidents and some other issues. Neither is it unusual that accident data is not available, not reliable or lacks impor
In this chapter, we will discuss the limitations of police accident data and the added value of health data as a complementary source. Several types of health organisations exist that cover a certain severity of traffic casualties. A number of medical indicators will be discussed, as well as methods to estimate the true number of serious injuries and the completeness of the police reporting. For t
Background: The incorporation of artificial intelligence (AI) into point-of-care ultrasound (POCUS) platforms has rapidly increased. The number of B-lines present on lung ultrasound (LUS) serve as a useful tool for the assessment of pulmonary congestion. Interpretation, however, requires experience and therefore AI automation has been pursued. This study aimed to test the agreement between the AI
The main goal of my studies was obtaining bulk acoustofluidic devices able to achieve high energy density inside a water-filled cavity. This led us to explore the interplay of sound and thermal effects more in details. Hence, this thesis covers both thermoacoustic effects in Bulk Acoustic Wave devices and a revisited approach for designing them, focusing on achieving good performance. Thermoacoust
The magnetic Laplacian on a planar domain under a strong constant magnetic field has eigenvalues close to the Landau levels. We study the case when the domain is a disc and the spectrum consists of branches of eigenvalues of one dimensional operators. Under Neumann boundary condition and strong magnetic field, we derive asymptotics of the eigenvalues with accurate estimates of exponentially small
Objective: To describe the SHIELD cohort in terms of symptoms indicative of early knee osteoarthritis (OA) and to investigate associations between patient characteristics (demographics, activity/injury-related) and these symptoms at 1 (cross-sectional) and 3 years (longitudinal) post anterior cruciate ligament reconstruction (ACLR). Method: 106 participants (50 % women, mean [SD] age 25 [5] years
Human-machine interfaces using electromyography (EMG) offer promising applications in control of prosthetic limbs, rehabilitation assessment, and assistive technologies. These applications rely on advanced algorithms that decode the activation patterns of muscles contractions. This paper presents a new approach to assess and decode muscle activity by localizing the origin of individual temporal pe
Bone morphogenetic protein 10 (BMP-10) is crucial for endothelial cell signaling via activin receptor-like kinase 1 (ALK1), a pathway central to vascular homeostasis and angiogenesis. Dysregulated BMP-10 signaling contributes to cardiovascular diseases and cancer, highlighting the need to control ALK1-mediated endothelial responses to BMP-10 for therapeutic development. BMP-10 biosynthesis involve
Background: Current guidelines for initial management of traumatic brain injury (TBI) support decision making, but they are rarely validated. The Scandinavian guideline for management of children with TBI (SNC16) was developed to minimise the use of cranial computed tomography (cCT) without compromising safety, but the performance of the guideline in a real-world population is unknown. We aimed to
Is being informed about a nudge detrimental to its effect? This paper reports results from an experimental online study testing the effects of transparency on the effectiveness of a default nudge while accounting for psychological reactance and response time. Overall and in line with earlier studies, we find no negative effect of transparency on average behaviour. Adding to the previous discussion
The widespread adoption of lithium-ion batteries (LIBs) for energy storage has introduced significant fire risks, particularly in confined and restricted environments such as tunnels. This study investigated thermal runaway (TR) behavior in a model tunnel at ventilation speeds ranging from 0 m/s to 2.5 m/s, using LiFePO4 (LFP) and LiNixCoyMnzO2 (NCM) batteries. The experiments identified two criti
Objective: The present study compared individual personality traits and demographic variables, i.e. sex, age, and socioeconomic status, in explaining mental health in a large representative adolescent Swedish high school survey. Method: This data collection on 15- to 18-year-olds (N = 10,288, response rate 79 %) was conducted in 2024 and included, for the first time, a brief Big Five personality m
Beslut om utlämning fattas av regeringen efter yttrande från Riksåklagaren. Om den eftersökte inte samtycker till utlämning yttrar sig även Högsta domstolen (HD). I den här analysen behandlar JP Infonets expert Christoffer Wong, universitetslektor i straff- och straffprocessrätt, processen i utlämningsärenden. Han diskuterar särskilt frågan om och när HD:s prövning bör omfatta förenligheten med Eu
Electron paramagnetic resonance of Cr3+ ions in β -Ga2O3 is investigated using terahertz spectroscopic ellipsometry under magnetic field sweeping, a technique that enables the polarization resolving capabilities of ellipsometry for magnetic resonance measurements. We employed a single-crystal chromium-doped β -Ga2O3 sample, grown by the Czochralski method, and performed ellipsometry measurements a
We describe a magnetic relation in analogy to the well-known dielectric Lyddane-Sachs-Teller relation [R. H. Lyddane et al., Phys. Rev. 59, 673 (1941)PHRVAO0031-899X10.1103/PhysRev.59.673]. This magnetic relation follows directly from the model equations for nuclear induction due to fast oscillating electromagnetic fields [F. Bloch, Phys. Rev. 70, 460 (1946)PHRVAO0031-899X10.1103/PhysRev.70.460] a
