The economic costs associated with currency crises following successful speculative attacks may motivate intervention by the public sector. This thesis uses macro data to examine the effects of two forms of public intervention with regard to debt inflows on the economic costs of a crisis. On the one hand, official creditors may provide debt financing to the country’s public sector. On the other,
Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e., the Kronecker model and the Weichselberger model, and a cluster-based m
The protein hemoglobin (Hb) is vital for us humans to ensure enough oxygen replacement in the body. Hb-resembling proteins also exist in plants, these are called phytoglobins (Pgbs). Pgbs are very interesting since they can play a considerable role in the development of blood substitutes and iron supplements for human use. A few years ago, genes that code for Pgb in sugar beet were found and ident
Urban last mile delivery has become an increasingly relevant topic in this day and age, where the urban population is growing at the same time as climate change forces nations to limit emissions. The demand for fast and flexible deliveries in urban areas accelerates, which further escalates the need to optimize these last mile deliveries since they are the most polluting part of the supply chain.
In recent years, as Internet of Things (IoT) and machine learning technologies have advanced, there has been increasing interest in the study of energy-efficient and flexible architectures for embedded systems. To bridge the performance gap between microprocessors and memory systems, Near-Data Processing (NDP) was introduced. Although some works have implemented NDP, few of them utilize the microp
Reaching the targets of the Paris Agreement requires acceleration of low-carbon energy transitions. At the same time, it is not fully understood why some technologies spread more rapidly and widely than others. This thesis advances our understanding of the diffusion of large-scale low-carbon technologies by bridging technology diffusion studies and political economy of transitions. Through combini
This project was done for the company Beijer Electronics Products AB and the task was given by the hardware development department of the company. The project was about developing a concept proposal for a new generation operator panels. This was done to inspire the product developers at Beijer Electronics with innovative ideas before the actual operator panel development. More in detail the object
Novel rotating-cylinder sliding vane rotary compressors (RC-SVRCs) are promising machines in energy conversion systems due to extremely low friction. However, three-dimensional visual investigations on geometrical optimizations of RC-SVRCs are highly limited. Besides, most flow mechanisms and leakage flow affected by geometric structures have not been fully revealed yet. Therefore, the sliding van
Animal species differ considerably in their ability to fight off infections. Finding the genetic basis of these differences is not easy, as the immune response is comprised of a complex network of proteins that interact with one another to defend the body against infection. Here, we used population- and comparative genomics to study the evolutionary forces acting on the innate immune system in nat
Digital sustainability education (DSE) is becoming increasingly relevant in higher Education for Sustainable Development (ESD) and spreads globally. DSE is fueled by the Covid-19-pandemic and urges lecturers, students and universities alike to break new ground in academic teaching. DSE impacts established approaches to ESD and raises questions of ... appropriate online teaching concepts, tools and
Study objectives: Following traumatic events, people frequently experience distressing, involuntary memories of them (i.e., intrusions). Accumulating evidence suggests that sleep facilitates voluntary memory retrieval by supporting memory consolidation, but it is less clear what effect sleep has on intrusions. Recent research has used distressing film clips as a proxy for traumatizing events and e
Aim: To establish outcomes of a priority setting partnership between participants with diabetes mellitus and clinicians to identify the top 10 research priorities for preventing and treating diabetic foot ulcers (DFUs). Methods: Due to the COVID-19 pandemic, the James Lind Alliance Priority Setting Partnership process was adapted into a digital format which involved a pilot survey to identify unde
Objectives: To evaluate the discrimination, calibration, and net benefit performance of the Prostate Cancer Prevention Trial Risk Calculator (PCPTRC) across five European randomized study of screening for prostate cancer (ERSPC), 1 United Kingdom, 1 Austrian, and 3 US biopsy cohorts. Methods: PCPTRC risks were calculated for 25,733 biopsies using prostate-specific antigen (PSA), digital rectal exa
Objectives: To understand the comparability of serum prostate-specific antigen (PSA) determinations across assays and storage time. Methods: Serum PSA levels were determined for men aged 40 to 79 years from the clinical subset of the Olmsted County Study of Urinary Symptoms and Health Status Among Men on fresh samples and after a median of 32 months on banked samples, frozen at -70 °C. Baseline se
Cervical cancer is one of the most recurrent and dangerous female cancers in Algeria and worldwide. It is mainly caused by human papillomaviruses (HPV), which can induce other cancers as well. Although it can be fatal, cervical cancer is one of the most preventable and manageable cancers. While HPV vaccination is the key weapon to win the battle against this pathology, it is still not approved in
Dietary phosphorus restrictions are usually recommended for people on haemodialysis, although its impact on patient-relevant outcomes is uncertain. We aimed to evaluate the association between total phosphorus intake and its sources with mortality in haemodialysis. Phosphorus intake was ascertained within the DIET-HD study in 8110 adults on haemodialysis. Adjusted Cox regression analyses were cond
Objective. The diagnostic yield of sural nerve biopsy (SNB) in vasculitis is uncertain. Our aim was to document relevant characteristics of patients undergoing SNB in the investigation of vasculitis; determine the diagnostic yield; relate positive biopsy findings to patient demographic, laboratory, and clinical variables; and to calculate the rate of surgical complications. Methods. Patients with
