In the course of a few months in 1997, about 20 per cent of Stockholm Stock Exchange's primary-list firms transferred to the Exchange's secondary list due to a new tax policy. Drawing on a theory of social influence, we suggest that the transfer decisions depended both on the firms' social embeddedness with other firms in the population at risk and their economic predisposition to make such transf
This paper describes the development of a novel modelling tool for evaluation of solid oxide fuel cell (SOFC) performance. An artificial neural network (ANN) is trained with a reduced amount of data generated by a validated cell model, and it is then capable of learning the generic functional relationship between inputs and outputs of the system. Once the network is trained, the ANN-driven simulat
In this work, we reconstructed in vitro the behavior of two motor proteins-myosin and actin-responsible for the mechanical action of muscle cells. By transferring this in vivo system to an artificial environment, we were able to study the interaction between the proteins in more detail, as well as investigating the central mechanism of force production. Nm-patterning by e-beam lithography (EBL) co
A sensitive method for the detection of staphylococcal enterotoxin B (SEB) using a flow-injection capacitive biosensor is presented. SEB was purified from a crude culture filtrate of Staphylococcus aureus through three chromatographic steps. The first two steps were based on ion-exchange chromatography, and the last step was carried out on a gel filtration column. The SEB recovery values after the
A new mu-oxo diiron(III) complex of the lithium salt of the pyridine-based unsymmetrical ligand 3-[(3-{[bis(pyridin-2-ylmethyl)amino]methyl}-2-hydroxy-5-methylbenzyl)(pyridin2-ylmethyl)amino] propanoate (LiDPCPMPP), [Fe-2(mu-O)(LiDPCPMPP)(2)](ClO4)(2), has been synthesized and characterized. The ability of the complex to catalyze oxidation of several alkanes and alkenes has been investigated by us

Syfte: Studien undersöker om det på ett reliabelt sätt går att använda en modifierad version av Pati-ent Attachment to Therapist Rating Scale (PAT-RS) för att skatta anknytningsmönster från patient till terapeut utifrån inspelade psykoterapisessioner från fjärde sessionen under en korttidsterapi. Metod: Två oberoende observatörer har skattat anknytningsmönster från patient till terapeut utifrån 30Objective: This thesis investigates if it is possible to use a modified version of Patient Attachment to Therapist Rating Scale (PAT-RS) estimating attachment style between patient and therapist dur- ing an early stage of short term psychotherapy in a reliable way using recorded psychotherapy ses- sions. Method: Recorded material from 30 psychotherapy sessions have been separately estimated by two
As our lives ever increasingly move online, the influence of social media is constantly growing. It has however proven difficult for legislators to keep up with rapid development of online spaces. Therefore, legislative control has largely been left to the social media platforms. To see if this is a good solution, this paper aims to analyze Twitters terms of use, rules, guidelines, and policies, i
Loss functions are a crucial part of image processing when using modern neural networks, trained with stochastic gradient descent. There exist multiple loss functions today, some claiming to be perceptual. Researchers at NVIDIA recently published a proposal of such a metric called FLIP. This led to our work on this thesis where we present a comparison between multiple loss functions, both establis
An ongoing discussion in Sweden regards the reduced green areas as a consequence of urbanization and housing shortages. Previous research emphasizes positive effects that nature has to our health. Public outdoor environments such as playgrounds or parks are the basis of children's play in their neighborhood. To plan and create good environ-ments, for children to grow up in, is therefore necess
Entanglement is a fundamental aspect of quantum computation and quantum information processes. In this work, we analyse the entanglement of two microwave resonators when connected to a semiconductor double quantum dot. The two-mode squeezing operation is a commonly used tool in entanglement creation and, based on this, we utilise the related two-mode two-photon Jaynes-Cummings model in the theoret
Pornografi har de senaste decennierna blivit alltmer lättillgängligt och närmast oändligt i utbud. Det kan införskaffas anonymt och gratis. Användandet är utbrett och börjar ofta i unga åldrar. Trots att många rapporterar att deras användande av pornografi och annat sexuellt explicit material (SEM) är problematiskt saknas en vedertagen konceptualisering. Denna studies syfte var att beskriva den raPornography has become increasingly accessible and almost infinite in supply. It can be used anonymously and for free. The use is widespread and often starts at a young age. Despite large numbers of people reporting problematic use of pornography and other sexually explicit material (SEM), the problem lacks an officially recognized conceptualization. The purpose of the present study was to investi
This thesis examines the evolution of markups among the largest publicly listed firms in Sweden, represented by the OMXS30 index, during the period surrounding the COVID-19 pandemic from 2018 to 2024. The study assesses whether changes in firms’ pricing power contributed to Sweden’s inflationary and subsequent disinflationary dynamics. Using a microeconomic production function approach developed b
This paper presents a new τ-lepton reconstruction and identification procedure at the ATLAS detector at the Large Hadron Collider, which leads to significantly improved performance in the case of physics processes where a highly boosted pair of τ-leptons is produced and one τ-lepton decays into a muon and two neutrinos (τμ), and the other decays into hadrons and one neutrino (τhad). By removing th
Cement hydration kinetics are controlled by clinker composition, water addition, sulfate availability and fineness. The analytical access to the first hour of hydration is limited. Here a new setup is introduced to record the initial 30-60 minutes of hydration on a routine basis with isothermal calorimetry. Fast isothermal calorimetry is fully quantitative. Reproducibility is reported in terms of
