Access to digital infrastructure in highly digitalized societies is shaped not only by the availability of technology but also by the administrative arrangements that govern access to it. This study examines how non-EU international students at Lund University experience and navigate exclusion from Sweden’s digital financial infrastructure through the case of Swish, a mobile payment system widely
Technical drawings play an important role in many industrial processes, including product development, manufacturing, and lifecycle management, by representing the product definition. The purpose of the study was to investigate which processes influence technical drawing creation and management, what challenges are associated with these processes, and how these challenges can be addressed through
This thesis presents the design and schematic-level simulation of a highly linear mixer-first receiver front-end implemented in CMOS, targeting improved robustness against strong input signals. The proposed architecture employs a current-mode passive mixer directly loaded by a low-impedance transimpedance amplifier (TIA) in order to minimize the voltage swing at the mixer output and thereby enhanc
Developing high-temperature proton exchange membranes (HT-PEMs) that simultaneously achieve high proton conductivity, strong phosphoric acid (PA) retention, and long-term chemical stability remains a major challenge, particularly due to PA-induced plasticization and radical-induced oxidative degradation. Here, we develop a side-chain engineering strategy to decouple PA-binding sites from the polym
With approximately 94 percent of traffic accidents being caused by human error, improving driver behaviour has the potential to save lives. To encourage safer driving, Volvo Cars is developing a Safety Coach feature for their mobile application. However, pilot studies of a minimum viable product (MVP) indicated low user retention, suggesting the need for design elements that better support user en
Universities are widely understood to be sites of free expression, knowledge-seeking institutions that serve the public good while encouraging personal development of individuals. They typically uphold and communicate institutional integrity and ethics, seeking to encourage open communication, equip students with critical thinking, and foster civil participation. For the Social Sciences, questions
OBJECTIVE: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are chronic, relapsing inflammatory diseases, yet reliable biomarkers for detecting relapse and organ involvement remain limited. This study aimed to identify plasma protein biomarkers that distinguish active disease from remission and to explore markers associated with lung and kidney involvement.METHODS: Plasma
Background: Data are lacking on left ventricular ejection fraction (LVEF) trajectory following myocardial infarction (MI). Objectives: This study aimed to evaluate the impact of LVEF trajectory after percutaneous coronary intervention (PCI) for MI on long-term outcomes. Methods: Patients undergoing PCI for MI (2007-2022) with serial echocardiograms were identified in the Swedish Coronary Angiograp
PURPOSE: Provision of adequate support is much needed to secure equal educational opportunities for students with developmental language disorder (DLD). Important perspectives on support provision and its impact on academic progress are held by school professionals, caregivers, and students with DLD. This study sought to further the current knowledge on the perceived relation between educational s
Background and purpose: Stereotactic radiosurgery (SRS) requires high positional accuracy to safely deliver large doses. This study evaluated an integrated surface- and image-guided radiotherapy (SGRT-IGRT) system by analysing (1) the agreement between thermo-optical and stereoscopic X-ray positioning, and (2) the impact of intra-fractional workflows on treatment accuracy and time. Materials and m
We show exponential lower bounds on resolution proof length for pigeonhole principle (PHP) formulas and perfect matching formulas over highly unbalanced, sparse expander graphs, thus answering the challenge to establish strong lower bounds in the regime between balanced constant-degree expanders as in [Ben-Sasson and Wigderson’01] and highly unbalanced, dense graphs as in [Raz’04] and [Razborov’03
AIMS: Diagnosing heart failure with preserved ejection fraction (HFpEF) remains challenging, particularly in older individuals. We hypothesized that machine learning (ML) approaches could improve diagnostic accuracy compared with HFpEF scores.METHODS: We evaluated the diagnostic performance of four supervised ML algorithms (random forest [RF], extreme gradient boosting [XGBoost], support vector ma
We explore mission assignment and task offloading in Open Radio Access Network (Open RAN)-enabled intelligent transportation systems (ITS), where autonomous vehicles utilize mobile edge computing for efficient processing. Existing studies often overlook mission dependencies and offloading costs, leading to suboptimal decisions. To address this, we formulate a novel optimization problem that integr
Cu-based ternary catalysts often outperform their binary counterparts in the hydrogenation of CO2 to methanol. Unraveling the underlying synergistic effects among multiple components remains challenging and requires comprehensive operando characterization. In this study, we present a detailed investigation into the synergistic Cu−Zn−Zr interactions in inverse ZnZrOx/Cu catalysts, which show strong
The construction industry is a major contributor to resource consumption and waste generation in the EU, making the transition to circular construction essential. Reuse of building products is an important circular strategy, but large-scale implementation is hindered by limited market maturity and uncertainty regarding product availability. This study aims to investigate the gap between reported a
The diagnostic accuracy of AIDOC-VO, the first commercial artificial intelligence tool for intracranial large-and medium-vessel occlusion (LVO/MeVO) detection on head-and-neck CT angiography (CTA), was evaluated in a multicenter emergency setting. A prospective diagnostic-accuracy study of 3,031 adult CT angiograms (mean age, 67.3 years ± 16.4 [SD]; 1,549 females) acquired March-July 2024 across a
The power systems of drilling rigs have changed considerably since the early days of steam driven machinery. This paper reviews that progression, from mechanical and diesel electric configurations through to modern hybrid and renewable integrated systems, with a focus on the power conversion technologies that enable each stage. Coverage includes the electrical architecture of drilling rig power sy
PurposeIn the transformation to the circular economy, circular logistics nodes are becoming increasingly important to, for example, match supply and demand, coordinate flows, increase logistics efficiency and customer utility, and reduce environmental impact. The purpose of this study is to expand our theoretical understanding of the circular retail transformation and its implications for circular
The healthcare systems of today are facing large challenges, with increasing amounts of patients and overworked hospital staff. Prostate cancer and Alzheimer’s disease are two of the most prevalent diseases, with incidence numbers expected to rise over the coming decade. Medical imaging plays a central role in current diagnostic procedures for these diseases, enabling the potential use of machine-
