New series of proton-conducting polymer composite membranes were fabricated by impregnating a cobalt metal–organic framework (Co-MOF) into a sulfonated polyethersulfone/poly(vinyl alcohol) (SPES/PVA) blend matrix. Post-sulfonation technique is used to sulfonate polyethersulfone using chlorosulfonic acid as a sulfonating agent. The presence of hydrophilic functional moieties in SPES and PVA contrib
Developing a conceptual framework of strategic silence and applying it to various domains of Central Asian international relations, this book uncovers how silence allows states to navigate structural constraints, maintain flexibility, and assert subtle forms of resistance or alignment. Strategic ambiguity and restraint often characterise Central Asia’s response to major geopolitical shifts. This b
Cardiovascular disease (CVD) is a major long-term complication and the leading cause of morbidity and mortality among individuals with type 1 diabetes (T1D), with a substantially higher prevalence compared to the general population and driven by multiple interrelated risk factors—underscoring the urgent need for accurate risk assessment. To support more tailored approaches to CVD prevention, recen
Background: Cannabis, the most consumed illicit drug globally, has been legal for non-medical use in Canada since 2018. Problematic internet use is considered a behavioral addiction involving excessive online activities (e.g., social media, video watching), which can cause social isolation, family issues, psychological distress, and even suicide ideation. Studies mainly conducted with adolescents
Correlation functions and correlation lengths are frequently used to describe phase transitions in quantum systems, but they require an explicit choice of observables. The recently introduced information lattice instead provides an observable-independent way to identify where and at which scale information is contained in quantum lattice models. Here, we use it to study the difference between the
Background: Preoperative lymph node staging in upper tract urothelial carcinoma (UTUC) using 18F-Fluorodeoxyglucose (FDG) positron emission tomography combined with computed tomography (PET-CT) is sparsely reported. Objective: This study investigates the diagnostic accuracy of PET-CT and conventional computed tomography (CT) for detecting regional lymph node metastases in patients with UTUC, using
Abstract – There is a growing interest in the genomic and developmental basis of discrete or multimodal phenotypes governed by genetic polymorphisms. Recent research has uncovered the genomic basis of such polymorphisms and their maintenance through balancing selection such as negative frequency-dependent selection (NFDS). Such polymorphisms often originate through structural genomic changes or th
International mobility can provide students with opportunities for intercultural learning and developing language skills. Language proficiency is also a factor in the choice of a host university and satisfaction with study abroad programmes. The present study examines student reflections on the role language played in their academic, social, and personal experiences during international mobility,
Teledermatology is increasingly used for the assessment of suspicious skin tumours, yet referral content remains poorly standardized. To develop a European expert consensus on the essential clinical and visual variables required for teledermatological assessment of primary skin tumours. A 3-round modified Delphi study was conducted among experienced dermatologists. In round 1, participants propose
Within-species size variation is known to create asymmetries in resource competition and, increasingly, is recognized to correlate with systematic shifts in behavioral responses (e.g., boldness) between juveniles and adults. The combined effects of these asymmetries on population stability, especially under anthropogenic pressures, however, remain poorly understood. We use a size-structured consum
BACKGROUND The global prevalence of functional constipation is approximately 12%. It is characterized by infrequent complete spontaneous bowel movements (CSBMs), hard or lumpy stools, straining during defecation, and has a negative impact on quality of life (QoL). The probiotic strain Lactiplantibacillus plantarum (L. plantarum) 299v (Lp299v) has been demonstrated to be efficacious in irritable bo
In recent years, the utilisation of biogas has attracted attention as an alternative to fossil fuels and as a countermeasure against global warming. Efficient utilisation of biogas requires biogas upgrading, and with technological advances, membrane separation using small-pore zeolite membranes with excellent molecular sieving effects is becoming mainstream. In this study, biogas separation was pe
As the climate crisis intensifies, climate adaptation becomes increasingly urgent and necessary. This holds especially true for Small Island Developing States, who, despite bearing little responsibility in creating the problem, are uniquely vulnerable to slow onset and extreme weather events. To address climate impacts in developing countries, the international community has set up pathways to hel
This thesis compares the entrepreneurial contexts of Lund, Sweden, and Toronto, Canada to examine whether Creative Destruction Lab (CDL), a non-profit accelerator founded in Toronto, would fit within Lund's ecosystem. Two research questions are addressed: what similarities and differences exist between the entrepreneurial contexts of Lund and Toronto, and how a CDL site would mesh with Lund
The Shallow Neural Network (SNN) is one of the most basic forms of machine learning models. It has a high theoretical representational capacity, but this is often not realized in practice, in part due to overfitting. This thesis proposes a new regularization method and compares it against existing techniques across a range of tasks using SNNs. The proposed method, norm-preserving regularization (N
This thesis investigates the design and implementation of Model Predictive Control (MPC) and motion planning to enable an Unmanned Surface Vessel (USV) to perform autonomous escort missions. The objectives were to assess how the control architecture could utilize preexisting internal USV controllers and handle dynamic obstacles. Furthermore, how the controller architecture should be organized and
Collaborative robots, or cobots, are increasingly used in industrial automation, where they work in flexible, semi-modular configurations while still being expected to meet demanding positioning accuracy requirements. After a joint is replaced on such a robot, the resulting joint zero offset typically forces a full kinematic recalibration before the robot can return to service, causing downtime an
Visual Autoregressive models (VARs) are a recent class of text-to-image generation models that have achieved state-of-the-art image-generation quality. Compared with diffusion-based models, VARs can generate images much faster, in some settings producing an image in under a second. This speed relies heavily on KV-caching, which introduces a considerable memory overhead, up to 10 GB to generate one
Control systems at European Spallation Source (ESS) are large-scale, complex and difficult to model using traditional approaches. Data-driven methods are therefore required to model systems such as the Cryogenic Moderator System (CMS) and Target Helium Cooling System (THCS). This work presents a control-system modeling approach based on the Transformer and Long Short-Term Memory (LSTM), enabling l
Drones are becoming more common everywhere, and with that comes the risk of unauthorized drones entering protected areas such as airports or military sites. One way to deal with this is to send out another drone to find and follow the unknown one for closer inspection. This project built a system that does exactly that. A drone equipped with a camera is able to automatically spot another drone, es
