Aberrant protein aggregation into amyloid fibrils is often catalyzed by interfaces. Therefore, it is important to characterize the surface activity of chaperone proteins having the ability to suppress amyloid formation. The air–water interface is of large practical significance in experimental setups used to study aggregation kinetics in vitro, but in addition, the binding of chaperones to hydroph
Breakthroughs in battery research are imperative to provide society with batteries that are safe and sustainable, have a high energy density, and have a long cycle life at low cost. Recent advances in research methodologies, the emergence of new market opportunities, and strategic funding schemes have allowed not only large, but also small companies, universities, and public research organizations
Precisely determining the oxidation states of metal cations within variable-valence transition metal oxides remains a significant challenge, yet it is crucial for understanding and predicting the properties of these technologically important materials. Iron oxides, in particular, exhibit a remarkable diversity of electronic structures due to the variable valence states of iron (Fe 2+ and Fe 3+). A
UNLABELLED: The primary objective of this study was to investigate whether ligand-receptor interactions (LRIs) between IGHG and FCGR gene products are associated with progression to type 1 diabetes (T1D). Using two completed clinical trials (DPT-1 and TN07), we applied next-generation targeted sequencing to genotype IGHG and FCGR genes in a cohort of 1,214 individuals and assessed LRI associations
Detta arbete undersöker tillväxteffekten av andelen förnybar elproduktion av den totala nationella elmixen med paneldata från 49 afrikanska länder 1996-2020, i Fixed Effects-regressioner. Förnybar energi framhålls ofta som en nyckelfaktor för hållbar utveckling, samtidigt som sambandet mellan förnybar energi och ekonomisk tillväxt är omdiskuterat i tidigare forskning. Resultaten i denna undersökni
This study investigates the effects of climate policy uncertainty (CPU) shocks on metal spot prices from 1990 to 2025 using impulse response analysis within a Vector Auto-Regressive (VAR) framework. The results indicate that price responses are time-varying and heterogeneous across metals. Overall, CPU shocks are found to have contemporaneous negative effects with short-term persistence. Although
This paper is an empirical study on the effect that different weather conditions have on electricity prices in Denmark between the 29th of April 2023 and the 29th of April 2025. The study analyses how daily time series data for wind speed, temperature and solar exposure impacts daily electricity prices in respective bidding areas. The findings of this paper concludes that each of the measured weat
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
This thesis examines how heterogeneous U.S. firms respond to trade policy announcements issued by President Donald Trump during his two administrations (2017–2021 and from 2025 onward). The results imply that among the 144 firms studied, export-oriented firms were more negatively affected by the trade policy announcements chosen for this study than non-export-oriented firms. These findings are con
This thesis asks whether European Union candidacy, as an intermediate stage prior to accession, increases bilateral trade between Western Balkan candidates and EU members. The methodology combines a structural-gravity framework estimated by PPML with a heterogeneity-robust staggered difference-in-differences event study, using directional dyad–year goods trade for 2006–2019 and exporter×year, impo
This thesis investigates the impacts of three major global disruptions: the COVID-19 pandemic, the Suez Canal blockage, and the Russia-Ukraine war on Sweden’s automotive exports, a critical sector contributing approximately 15% to Sweden’s total goods exports. Utilizing monthly export data from 2017 to 2024 and employing a Seasonal Auto-Regressive Integrated Moving Average model with exogenous inp
This study investigates how different monetary policy tools have influenced deviations from Covered Interest Parity (CIP) in the USD/SEK 3-month cross-currency basis from 2007 to 2023. Using weekly data and OLS regression with Newey-West standard errors, the analysis evaluates the impact of policy-rate changes, quantitative easing (QE), and central-bank swap lines implemented by the Federal Reserv
In this text we develop a model of countries deciding on mitigation levels of CO2 in a tit-for-tat manner. Taking key ideas from earlier papers, we construct a payoff framework which describes free-riding incentives and which assesses the utility of countries' discounted future output - an output which is reduced by both abatement costs and climate damage. We then, by means of a differential e
Background: Chronic kidney disease (CKD) affects 6–10% of adults and often remains undiagnosed until advanced stages, leading to inadequate management. This study compared diagnosed, proxy-diagnosed, and undiagnosed CKD patients regarding prevalence, clinical assessment, nephroprotective treatment, healthcare utilization, and mortality. Methods: This retrospective observational study analyzed Regi
Self-harm, including nonsuicidal self-injury and suicide attempts, is common among youth, associated with elevated psychopathology, suicide risk, and increased demand for clinical services. Despite advances in understanding and treatment, few interventions have demonstrated efficacy in randomized controlled trials (RCTs), which are considered the gold standard for evaluating treatment effects by r
Characteristic Mode analysis is a widely used technique in antenna design, providing insight into the fundamental electromagnetic behavior of radiating structures. In this paper, we establish fundamental bounds on the slope of characteristic mode eigenvalues and angles, demonstrating that their rate of change is subject to fundamental constraints for all possible realizations within a given design
The chapter summarizes the different methods available for damage repair after water and/or fire events. Different drying methods as well as their advantages and disadvantages are discussed. This is done separately for timber framing and mass timber constructions. The section for repair after fire events points out the different steps that should be taken after a fire event. This includes methods
In Nordic countries, demand response (DR) programs are critical for enhancing energy flexibility and reducing peak electricity consumption in buildings and industry. Accurate short-term demand forecasting is essential to support these programs, especially in the context of cities with varying levels of data availability. This paper compares three different forecasting approaches for hourly electri
During the last two decades, an active line of research in proof complexity has been into the space complexity of proofs and how space is related to other measures. By now these aspects of the resolution proof system are fairly well understood, but many open problems remain for the related but stronger proof system polynomial calculus (PC/PCR). For instance, the space complexity of many standard “
This article explores the regional embeddedness of bioeconomy innovations in Germany, focusing on “flagship” innovation projects that exemplify the challenges and opportunities of systemic changes towards bioeconomies. While bioeconomies have been promoted as solutions to global challenges and opportunities for sustainable regional development, there are ongoing debates about the actual benefits o
