The availability of light pulses down to the attosecond timescale has led to the development of spectroscopic methods capable of resolving the dynamics of electrons. By studying the interference of electron wave packets (EWP) on their natural timescales, greater understanding of the dynamics can be gained. An attosecond pump-probe technique has been applied previously in Lund to study attosecond
This paper examines the applicability of three licensing models, compulsory licensing, free licensing and FRAND licensing, to green technology patent pools. Given that green technologies are critical in addressing global environmental challenges and achieving the SDGs, they can be effective in balancing incentives for innovation with wider dissemination of technologies. This study evaluates ea
Syftet med denna studie är att kartlägga självrapporterade symtom som drabbar tal/röst- samt sväljning hos nydiagnostiserade patienter med Parkinsons sjukdom (PS) innan medicinering påbörjats, så kallade de novo-patienter. Studien undersöker eventuella samband mellan dessa symtom och andra självupplevda symtom som drabbar gång- och balansförmågan (inklusive fall) samt salivöverskott. Studien är en
The European Union and China mark 50 years of diplomatic relations in 2025 amidst intensifying international tensions. This research explored the Chinese international relations (IR) scholarly discourse to identify how Chinese academics perceive, interpret, and represent the EU. Drawing from 23 publications and two in-depth semi-structured interviews with Chinese scholars, the study found that the
Modebranschens tillväxt online har förändrat konsumenternas köpvanor, men har även bidragit till en ökning av deras returer. Detta har i sin tur medfört påtagliga miljömässiga konsekvenser för samhället. Konsumenter uppskattar företagens milda returpolicy, men detta har bidragit till en problematik där de beställer fler kläder än vad de faktiskt behöver. Allt fler företag har börjat implementera r
Next-generation sequencing (NGS) has transformed the study of antibody repertoires by enabling high-throughput, in-depth analysis of immune diversity and antigen-driven selection. When paired with in vitro display technologies, NGS offers unparalleled resolution in characterizing antibody libraries, but also presents substantial computational challenges due to the highly variable nature of antibod
With the development of high-throughput sequencing technology, the acquisition of large-scale human genome variation data has become increasingly prevalent, offering new opportunities for biomedical research. Therefore, obtaining meaningful information from high-throughput data has become a key task in related scientific research fields. However, how to quickly identify potential pathogenic sites
Background Brain metastases are a common complication in cancer, particularly in patients with breast cancer, lung cancer, and melanoma, and are associated with poor prognosis. Understanding the spatial organization of tumor and immune cells is critical for uncovering the mechanisms of metastasis. Spatial transcriptomics technologies now allow gene expression profiling while preserving tissue arch
The brand Carhartt WIP has been working with establishing their brand image through social media that includes several collections with famous skate companies and posts including famous skaters from their team. Their clothing consisting of big silhouettes and good quality has been valued by the skate - community. Therefore this essay studies how Carhartt WIP is contributing to identity and what bo
Background: Gender differences in palliative care is an under-researched area, both internationally and in Sweden. A regional pilot study by our research group indicated that men have greater unmet palliative care needs prior to referral. Building on these findings, the aim of this study was to examine gender differences in the quality of care received at the end of life within specialized palliat
This thesis investigates sensorless methods for detecting collisions and added weight in dual motor-driven industrial doors, to enhance safety without additional hardware. The study is grounded in the safety requirements outlined in EN 12453:2017 and conducted in collaboration with ASSA ABLOY. By monitoring deviations in the torque-producing current (IQ) from the motors, the developed methods iden
This master thesis presents the development of a vision-based feedback control system for automating sample placement in a virtual neutron beam emulated using a laser. The thesis was carried out on behalf of the European Spallation Source (ESS) to investigate the feasibility, possibilities and limitations of using a robotic automation system for sample alignment. Due to the radioactive research en
Glioblastoma (GBM) remains one of the most aggressive and treatment-resistant brain tumors, with limited systemic therapeutic options and high recurrence rates. New treatment modalities in oncology, including antibody-drug conjugates and CAR-T cells, target the tumor cell surfaceome. However, despite extensive genomic and transcriptomic profiling, actionable surface antigens for targeted immunothe
Alzheimer’s disease (AD) is characterized by amyloid-β (Aβ) plaque deposition, tau pathology, and neuroinflammation, with genetic variants in the apolipoprotein E (APOE) gene representing the strongest risk factor for late-onset AD. Microglia, the brain’s resident immune cells, are increasingly recognized as central to disease progression through their roles in neuroinflammation and Aβ clearance.
Since the discovery of graphene in 2004, there has been intense and continuous research into the possibilities of creating other 2 dimensional (2D) materials. Since then, much progress has been made, resulting in many new metals, semiconductors, and insulators that can fill any number of roles from transistors to solar cells. In this thesis, I discuss hexagonal beryllium oxide (h-BeO) as a potenti
This study aims to explore how healthcare counselors in adult psychiatry in Region Skåne work with children as next of kin and the limitations and opportunities they experience in implementing a child’s perspective. The study is based on six semi-structured interviews with healthcare counselors. The material was analyzed thematically with an inductive approach. The results indicate that healthcare
The dissertation De argutis imaginibus was presented in 1725, in Uppsala, Sweden, by supervisor Lars Arrhenius and respondent Johannes J. Dalenius. The text contains various ideas regarding emblem studies, and concerns itself with emblems as well as other argutae imagines – “witful images”. This thesis aims to present an overview of the content of the dissertation, and to frame this with a cultura
We observe that, while predicting returns remain difficult and uncertain, volatility exhibit more persistence and predictability due to well-known patterns such as volatility clustering (Mandelbrot, 1967). We test whether short-horizon volatility forecasts can be used to time leverage in a passive index strategy so as to mitigate the growth penalty from volatility drag in leveraged exchange-traded
Pollinators such as Bombus terrestris play a vital role in ecosystem stability and agricultural productivity. Developing methods to estimate key biological traits such as age and weight is crucial for advancing ecological understanding and conservation efforts. In eusocial insects like B. terrestris, age and weight influence behaviour, task allocation, and survivability, but traditional methods fo
