We study applications of clustering (in particular, the Hamming k-center clustering problem) in the design of efficient and practical algorithms for computing an approximate and the exact arithmetic matrix product of two 0-1 rectangular matrices with clustered rows or columns, respectively. Our results in part can be regarded as an extension of the clustering-based approach to Boolean square matri
Accurate identification of anatomical structures is essential for safe congenital cardiac surgery and for the development of assistive robotic systems. However, scalable annotation of open-heart surgical video remains a major challenge due to dynamic tissue motion, occlusion, and anatomical variability. The aim of this study was to develop and evaluate a human-in-the-loop segmentation and tracking
Objectives: The Queen of Hearts (QoH) ECG artificial intelligence model has demonstrated improved sensitivity for detecting occlusion myocardial infarction (OMI) compared with STEMI criteria, but further validation is needed. We aimed to evaluate QoH's diagnostic performance in patients with chest pain at Swedish emergency departments (EDs). Methods: This retrospective analysis included consecutiv
Aim Infant massage has been suggested as a beneficial approach; however, evidence regarding how it is implemented within routine child health care remains limited. The aim of this observational study was to explore how infant massage education was enacted in a child health care setting, with a focus on infant behavior, caregiver–infant interaction, and group dynamics among caregivers during the se
In insects, antennal ionotropic receptors (IRs) play a crucial role in the detection of airborne chemicals. However, little functional information is available beyond drosophilids, particularly in terms of their functional evolution. In the present study, we functionally assayed IR75q.2 orthologues from eight moth species and found that three of them primarily responded to nonanoic acid, with seco
BACKGROUND: Bilateral basal ganglia calcifications (BGCs), if severe, are known hallmarks for idiopathic BGC disease (IBGC), but if milder, are often considered radiological findings of unknown significance. In previous studies, only a minority of patients with BGC had monogenic forms of IBGC.METHODS: We studied consecutive patients from a tertiary neurology clinic with bilateral BGCs of variable
BACKGROUND: It is now possible to acquire a fully diagnostic standard 12-lead electrocardiography (ECG) using a smartwatch, a smartphone app, and no additional hardware. This study aims to evaluate the predictive performance of advanced ECG (A-ECG) analysis applied to a smartwatch 12-lead ECG (SWECG) acquired using an Apple Watch in identifying cardiovascular risks among asymptomatic adults perfor
ObjectiveTo investigate degree of speech improvement and adverse effects after secondary velopharyngeal dysfunction (VPD) surgery in individuals with cleft palate with or without cleft lip/alveolus (CP ± L), and to examine whether any patient- or treatment-related factors were associated with treatment efficacy.DesignRetrospective intervention study.SettingA regional public care university hospita
As small modular reactors (SMRs) gain prominence in global discussions on the nuclear renaissance, questions about their societal acceptance become increasingly important. While technological and economic aspects dominate the early discourse, social dimensions—especially public attitudes—remain underexplored. This study examines how the Swedish public perceives SMRs in a period marked by a signifiAs small modular reactors (SMRs) gain prominence in global discussions in the nuclear renaissance, questions about their societal acceptance become increasingly important. Technological and economic aspects dominate the public debate while social dimensions – especially public attitudes – remain under explored. Based on a survey with citizens, this study examines how the Swedish public perceives S
This report maps the fossil and biogenic carbon flows that entered and left the Swedish economy in 2023 and discusses the implications of the Swedish climate target and some EU regulations on future carbon flows. The carbon flows were mapped according to Eurostat’s Economy Wide Material Flow Accounts (EW MFA) framework, focusing on anthropogenic carbon flows. The input flows in this framework cons
BackgroundChild-to-parent violence (CPV) is a serious but under-researched form of family violence. There is a lack of previous studies examining whether school violence and exposure to parental violence interact in their association with CPV. We hypothesize that involvement in school violence – as victim or perpetrator – is more strongly associated with physical CPV among individuals who have beeBackgroundChild-to-parent violence (CPV) is a serious but under-researched form of family violence.

Shifts in dissolved organic matter (DOM) composition, caused by seasonal or episodic events, can significantly alter the removal of per- and polyfluoroalkyl substances (PFAS) by granular activated carbon (GAC). To investigate how changes in feedwater composition impact PFAS removal in aged GAC, a 20-day experiment was conducted in eight parallel small-scale columns. Columns were filled with aged G
Aim: A prolonged time from diagnosis to start of radiotherapy (TTRT) for malignant disease may negatively influence survival, but studies in squamous cell carcinoma of the anus (SCCA) are largely lacking. The purpose of this study was to investigate the impact of TTRT on overall survival (OS) and anal cancer-specific survival (ACSS) in a nationwide population-based cohort from the Swedish Anal Can
Environmental destruction and extractivism are increasingly central to contemporary armed conflicts. Yet scholarship has paid limited attention to how these processes reshape landscapes over time and become embedded within strategies of war, governance, and resource control. This article examines the intersection of armed conflict, extractivism, and environmental change in Kurdish-dominant areas o
BACKGROUND: Many studies have shown that coffee and tea consumption is associated with diabetes. However, limited research exists on their effects on the risk of macrovascular complications in diabetic patients. Therefore, the purpose of this study was to examine the relationship between the intake of coffee and tea and macrovascular complications in patients with type 2 diabetes mellitus (T2DM).M
Background: Industrial adoption of third-party software tools requires more than technical performance evaluation, yet selection methods often underrepresent integration and organizational constraints. Objective: We develop CAFE, a context-aware framework for eliciting, assessing, and synthesizing tool selection requirements. Method: Following a Design Science Research approach, CAFE was developed
A brain-computer interface (BCI) controls a device using brain signals rather than conventional input modalities such as a computer mouse. Before use, the BCI must be calibrated. During the calibration process, the user repeatedly performs mental tasks while electroencephalography (EEG) data is collected. The calibration process is often time-consuming and tiresome for the user. One approach to re

However, the long-term effects of childhood adversity on marriage formation and social mobility remain insufficiently explored in historical populations. This study examines whether exposure to adverse early-life conditions affected the probability of entering a first maObjectives: Early-life conditions may influence later-life outcomes through biological scarring and selective survival mechanisms.

SaKu-projektet har varit ett tvåårigt, Forte-finansierat projekt som pågick mellan åren 2024 och 2026 och som har undersökt och vidareutvecklat samverkan mellan socialtjänsten i Lunds kommun och Socialhögskolan vid Lunds universitet, med särskilt fokus på hur kunskap kan cirkulera mellan praktik och akademi. Genom att kartlägga befintliga samverkansformer och pröva nya möjligheter till fördjupad s
