Shot-to-shot flat-field correction at X-ray free-electron lasers

X-ray free-electron lasers (XFELs) provide high-brilliance pulses, which offer unique opportunities for coherent X-ray imaging techniques, such as in-line holography. One of the fundamental steps to process in-line holographic data is flat-field correction, which mitigates imaging artifacts and, in turn, enables phase reconstructions. However, conventional flat-field correction approaches cannot c

Article 17 DSM Directive: the Swedish proposal (Part 2)

Commentary and analysis of the proposal of the Swedish Ministry of Justice (Ds 2021:30) concerning implementation of Article 17 Directive 2019/790 on copyright and related rights in the Digital Single Market (DSM Directive). Part 2 of 2.

Improving neural network classification of indigenous forest in New Zealand with phenological features

Accurate and up-to-date land cover maps inform and support effective management and policy decisions. Describing phenological changes in spectral response using time-series data may help to distinguish vegetation types, thereby allowing for more specificity within vegetation classification. In this research, we test this by classifying indigenous forest vegetation in New Zealand, using PlanetScope

Cultural ideals in the entrepreneurship industry

As both public and private organizations are spending resources on fostering entrepreneurship, we have witnessed the emergence of an entrepreneurship industry. Using the entrepreneurship industry in Sweden as a case and example, this chapter provides an explorative analysis the emergence, manifestations and consequences of cultural ideals within this industry. The analysis reveals how the entrepre

A Three Year Case Study with a Multidisciplinary Treatment of Relative Energy Deficiency and Anorexia in a Female Tennis Player

Tennis is an all-year racket sport requiring qualities such as speed, agility, flexibility, and endurance, as competitions may last up to five hours.Elite players have an estimated daily need of carbohydrate (CHO) between 6-10 g/kg to sustain high amounts of training and frequent competitions. Low energy availability (LEA), over time, may impair both health and performance. LEA may cause metabolic

Local multipliers and the growth of services: evidence from late nineteenth century USA, Great Britain, and Sweden

In the shadow of industry, the service sector substantially expanded during the late nineteenth century. This paper analyzes how the creation of industrial employment contributed to this growth of services. I leverage full-count census data from the United States, Great Britain, and Sweden to estimate local employment multipliers. I show that industrial growth was a key driver in the emergence of

Hydrogen plasma enhanced oxide removal on GaSb planar and nanowire surfaces

Due to its high hole-mobility, GaSb is a highly promising candidate for high-speed p-channels in electronic devices. However, GaSb exhibits a comparably thick native oxide causing detrimental interface defects, which has been proven difficult to remove. Here we present full oxide removal from GaSb surfaces using effective hydrogen plasma cleaning, studied in-situ by synchrotron-based X-ray photoel

Enhanced cGMP Interactor Rap Guanine Exchange Factor 4 (EPAC2) Expression and Activity in Degenerating Photoreceptors: : A Neuroprotective Response?

The disease retinitis pigmentosa (RP) leads to photoreceptor degeneration by a yet undefined mechanism(s). In several RP mouse models (i.e., rd mice), a high cyclic GMP (cGMP) level within photoreceptors is detected, suggesting that cGMP plays a role in degeneration. The rap guanine exchange factor 4 (EPAC2) is activated by cyclic AMP (cAMP) and is an accepted cGMP-interacting protein. It is uncle

The potential role of retinal cGMP-interaction partners within the degeneration mechanism causing Retinitis Pigmentosa

The eye disease Retinitis Pigmentosa (RP) represents a heterogeneous group of inherited retinal dystrophies, and it has been estimated that 1 in 3000 to 7000 people worldwide has the disease. The symptoms of RP are photoreceptor degeneration that leads to night blindness, followed by a decline in peripheral and central vision, and potential blindness. However, the mechanism(s) behind the photorece

Towards sugar- and lignin-based polyesters and polyurethanes with enhanced properties

The enormous production and consumption of fossil-based plastics has caused severe environmental challenges such as pollution of the ocean, increased CO2-emissions, and various health problems. Many ofthese concerns are intimately connected to the use of fossil fuels in the production of polymers. For this reason, there is a considerable interest to develop bio-based monomers to mitigate some of t

Interfacial behaviours of ionic fluids : Theory and simulations

This thesis and the papers included is an \textit{in silico} study of how charged particles interact and behave close to surfaces, and how to treat these interactions in simulations. This type of systems is found in widely different contexts, from capacitors to biological cells. The knowledge about such systems is therefore very important, as it affects many different areas, not in the least in sc

SIRPα - CD47 axis regulates dendritic cell-T cell interactions and TCR activation during T cell priming in spleen

The SIRPα-CD47 axis plays an important role in T cell recruitment to sites of immune reaction and inflammation but its role in T cell antigen priming is incompletely understood. Employing OTII TCR transgenic mice bred to Cd47-/- (Cd47KO) or SKI mice, a knock-in transgenic animal expressing non-signaling cytoplasmic-truncated SIRPα, we investigated how the SIRPα-CD47 axis contributes to antigen pri

Omställning till elbussar i svenska städer : Lärdomar om affärsmodeller, ägarskap och upphandling

Stadsbusstrafiken genomgår just nu en förändring där elbussar introduceras i snabb takt. Medan elbussar för några år sedan mestadels förekom i olika test- och pilotprojekt rullar det våren 2022 över 600 elbussar i ordinarie linjelagd kollektivtrafik i ca 25 olika svenska städer. Omställningen till elbussar karaktäriseras bland annat av att man gjort olika val avseende tillverkare och olika val avs

Translation and implementation of nature-based solutions in cities : Experimentation, learning and knowledge production

As part of current efforts to work towards sustainable development, find solutions to curb greenhouse gas emissions, and adapt cities to the effects of climate change, such as floods and extreme heat, there are high hopes that nature-based solutions (NBS) can support the transformation needed. Based on the knowledge that implementation and governance of urban NBS is still emerging and constrained

EU Competences in Crisis: Disentangling the Conflict between Monetary and Economic Legal Bases

This paper analyses the inherent competence conflict between the economic and the monetary policies under EU law. The particular policy areas have come under scrutiny with regards to the financial rescue packages issued in the course of the financial crisis (PSPP) as well as the Covid-19 pandemic (PEPP). Both crises have exposed some of the Union’s core morbidities: a lack of competence at EU leve

Unpaid care for parents, coresidence, and psychological well-being among older working-age men and women across Europe

Given population aging and the emphasis on in-home care, more working-age adults face demands of providing unpaid care to the elderly with potential implications for their wellbeing. Such effects likely vary across Europe because care is differently organized with more or less public support, dependence on family, and orientation toward gender equality. We studied the relationship between unpaid c
