Using an exact circuit analogy for the scattering of vector spherical waves, it is shown how the problem of determining the optimal scattering bounds for a homogeneous sphere in its high-contrast limit is identical to the closely related, and yet very different problem of finding the broadband tuning limits of the spherical waves. Using integral relations similar to Fano's broadband matching bound

Against the backdrop of the accelerated advancement of a new round of technological revolution and industrial transformation, the global economy is moving towards a development model driven by innovation as its core. Enterprises, as important carriers of technological progress and institutional innovation, are facing increasingly fierce market competition and transformational pressures. In this pr

Microvias are key enablers of next-generation high-speed and high-density electronic products. However, their signal-integrity performance can be affected by manufacturing-induced non-idealities, including tapered sidewalls caused by laser drilling and positional staggering caused by fabrication tolerances. This thesis investigates the impact of microvia vertical geometry and manufacturing-induced

At a time when journalism is said to be facing an epistemic crisis, the Baltic Sea islands tell a different story. On Åland, Gotland, Bornholm, and Saaremaa, local newsrooms still verify their information and connect to and sustain public life. Besides being a source of information, their journalism is also part of the islands’ shared identity – and a reminder that a free press is something worth

The presence of epistemic uncertainties in probabilistic modeling of structural performance implies that not only one but a multitude of possible models should be considered. When such models are utilized in the context of reliability and risk analysis, this does not pose any particular problem. In fact, epistemic and aleatory uncertainties may be treated without differentiation. However, in the c

This paper examines the influence of the Efficient Markets Hypothesis (EMH) on financial regulation, using a perspective drawing on arguments from the Philosophy of Science discipline.The paper aims to show that, prior to the global financial crisis, there already existed a large body of empirically observed asset price anomalies, which may be seen to contradict the notion of elastic demand curves

Culture and creativity are active but often overlooked processes in contemporary urbanisation. This paper contributes to scholarship on the cultural and creative industries, as well as urban placemaking on the margins, by adopting a placemaking approach in which artists are positioned at the centre of the analysis. The focus is on why artists choose to be located away from national cultural hubs,

Droughts have intensified under climate change, threatening ecosystem stability. While rising atmospheric CO2 concentrations may enhance vegetation drought resistance, the net effect remains uncertain amid concurrent warming. Here we combine ecological modeling with multi-source observations to investigate how CO2 and warming jointly regulate vegetation drought responses on the Qinghai-Tibetan Pla

Gärdenfors' and Levi's theories of rational belief changes will be compared to Kuhn's theory of scientific progress. Gärdenfors' proposal to analyze scientific revolutions in terms of big changes in epistemic entrenchment will be criticized for not being able to represent the important constituting function of the paradigms. Parts of Levi's theory that are incompatible with Ku

Previous studies have entertained the prospect of having 3D models substitute for their dry bone originals in osteological analysis. The objective of this study was to contribute to qualifying to what extent this may be possible given current technology. To this purpose, rather than choosing just a quantitative and purely technical method for evaluating models, as has been the norm in previous stu

Along with a deeper integrated world economy have countries discovered the benefits of harmonizing and simplifying the procedures linked to international trade, referred to as trade faciliation. A quite unexplored part of this field of research is yet how trade facilitation affects international investment flows, referred to as Foreign Direct Investments (FDI). In theory is trade facilitation affe

A large number of forest fires occurred in Sweden during the summer 2018 on a total area of 21 000 hectares. Between 300 and 500 residents were evacuated from their home due to these fires. This situation was unfamiliar in Sweden at the time, and the routines for dealing with such crisis were challenged. This thesis aimed to investigate the communication and information strategies, the evacuation

In this work we report the solvothermal synthesis of iron oxide and zinc oxide using a ternary eutectic mixture of choline chloride, urea and glycerol at three molar ratio of the components 1 : 1 : 1, 1 : 1.5 : 0.5 and 1 : 0.5 : 1.5. The synthesised iron oxide is nanocrystalline with a crystallite size of 67.5 ± 8.9 nm, however ZnO formed larger particles. Water and surfactants can be added to the

Title: The Influence of Institutional Investor Heterogeneity on Dividend Payouts: Evidence from Japan Purpose: To examine how institutional investor heterogeneity influences dividend payout policies in Japanese firms, and whether the implementation of Japan’s Corporate Governance Code (CG Code) in 2015 has modified this relationship. Methodology: The study employs fixed effects panel regressio
