Cellulose dissolution and regeneration is an increasingly active research field due to the direct relevance for numerous production processes and applications. The problem is not trivial since cellulose solvents are of remarkably different nature and thus the understanding of the subtle balance between the different interactions involved becomes difficult but crucial. There is a current discussion
The quality of student-teacher classroom interactions is important to learning, belonging, and success, particularly for students from groups that have been historically excluded from or marginalized in higher education. The literature commonly asserts that one necessary part of high-quality educational interactions (whether in person or online) is trust, but several scholars note that trust has n
If a disease affects fewer than 1 in 2 000, the European Union defines it as a rare disease. Globally, about 300 million people live with a rare disease, and in Sweden about 400 000. There are approximately 7 000 different rare diseases. The clinical picture varies from a single symptom to complex patterns with multiple organs affected, often combined with cognitive and motor impairment. At least
This chapter analyses responses of European policymakers to the Covid-19 pandemic’s first and second waves. It is based on an empirical analysis where patterns are sought between contextual factors and policy responses. The results shows that that macroeconomic conditions and policy interactions appear to matter more than countries’ number of Covid-19 cases. The level of government indebtedness ca
Although the nature and definition of populism are a source of considerable disagreement, there seems to be a minimal consensus by now that populism poses a number of threats to liberal democracy, and that public authorities should therefore act in defence of the latter. In searching for appropriate responses, however, most scholars draw from strategies for combatting anti-democratic or extremist
Accountability is central for accelerating progress towards achieving the Sustainable Development Goals (SDGs). It means to hold powerful actors answerable for how they turn agreements into action. Governments, who hold the main responsibility for SDG implementation, can in the ideal case be held accountable by voters, parliaments, civil society, and the media, for how they address the SDGs. At th
Accurately predicting the macroscopic behaviour of heterogeneous materials, particularly in thermo-electrically coupled systems, remains a challenging problem in materials science and engineering. Against this background, this study presents a comprehensive framework for the homogenisation of electrical conductors subject to strongly coupled thermo-electrical processes in (quasi-)stationary settin
A concept of germ graphs and the M-function formalism are employed to construct large families of isospectral and isoscattering graphs. This approach represents a complete departure from the original approach pioneered by Sunada, where isospectral graphs are obtained as quotients of a certain large symmetric graph. Using the M-function formalism and the symmetries of the graph itself we construct
A resolved optical image of a gamma-ray emitter would be of enormous scientific interest. For gamma-ray sources associated with interacting stars (colliding winds or novae), stellar intensity interferometry (SII), envisioned as a second observing mode at the Cherenkov Telescope Array Observatory (CTAO), could yield images of the systems in visible light. Recent radius measurements of massive stars
Mannosyl β-C-1 amidotriazoles have previously been reported to have higher selectivity for galectin-9N (N-terminal domain) than the corresponding galactoside C3 amidotriazoles have, which were more selective for galectin-3. This study further investigated this by synthesis of mono- and bis-aryltriazolyl mannoside analogues to known high-affinity galectin-3 galactosyl-derived inhibitors. Following
Protecting qubits from perturbations is a central challenge in quantum computing. Topological superconductors with separated Majorana bound states (MBSs) provide a strong form of protection that only depends on the locality of perturbations. While the link between MBS separation, robust degeneracy, and protected braiding is well understood in noninteracting systems, recent experimental progress in
Using detailed hand-collected data on firm ownership and board cultural diversity from Sweden, we find that foreign ownership is positively associated with board cultural diversity. This relationship is not an artifact of foreign owners joining the board, and it is not driven by firms with substantial foreign focus. The presence of foreign owners on nomination committees seems to be the channel th
Topological superconductors are appealing building blocks for robust and reliable quantum information processing. Most platforms for engineering topological superconductivity rely on a combination of superconductors, materials with intrinsic strong spin-orbit coupling, and external magnetic fields, detrimental for superconductivity. We propose a setup where a conventional Josephson junction is lin
