Garden escapes of Acer campestre spread as a cryptic invading gene pools and challenge the conservation of a unique ancient population in southern Scandinavia. The native gene pool consists of just 34 individuals and is listed as critically endangered. This population is more than 150 years old and represents a unique diorama into an almost extinct genetic diversity of the early 19th century. That
Experimental studies of infinitely repeated games typically consist of several indefinitely repeated games (“matches”) played in sequence with different partners each time, whereby match length, i.e. the number of stages of each game is randomly determined. Using a large meta data set on indefinitely repeated prisoner's dilemma games (Dal Bó and Fréchette, 2018) we demonstrate that the realized le
We report on the ultrafast dynamics of charge order and structural response during the photoinduced suppression of charge and orbital order in a mixed-valence manganite. Employing femtosecond time-resolved resonant x-ray diffraction below and at the Mn K absorption edge, we present a method to disentangle the transient charge order and structural dynamics in thin films of Pr0.5Ca0.5MnO3. Based on
Superantigens (SAgs) are bacterial enterotoxins produced by Staphylococcus aureus. Staphylococcal enterotoxin type A (SEA), a staphylococcal superantigen, has been shown to bind to the cytokine signalling receptor glycoprotein 130 (gp130). The structural details, as well as the exact physiological role of this interaction, remain unclear. Here, we describe the structural details of the SEA–gp130 c
The Swedish response to the pandemic at the national level has attracted considerable international attention, but little focus has been placed on the way municipalities dealt with the crisis. Using Hay's dimensions of politicization, namely the capacity for human agency, deliberation in the public domain, and social context, we analyze the politicization of the municipal response to the pandemic
Global value chains (‘GVCs’) have become a basic operative unit of economic production. Their development over the twentieth and twenty-first centuries has resulted in immense creation of wealth while linking together individuals, companies and economies across the world. But GVCs are also a major cause for environmental degradation, carbon emissions and human rights abuses—the ‘externalities’ of
The existence of a miscibility gap limits the range of solid compositions which are possible to achieve under near-equilibrium growth conditions. Circumventing the miscibility gap is of paramount importance for device fabrication. We propose that one of the suppression mechanisms is the nucleus surface energy and explain how the surface energy influences the miscibility gap during nucleation from
The mitochondrial genome almost exclusively encodes a handful of transmembrane constituents of the oxidative phosphorylation (OXPHOS) system. Coordinated expression of these genes ensures the correct stoichiometry of the system's components. Translation initiation in mitochondria is assisted by two general initiation factors mIF2 and mIF3, orthologues of which in bacteria are indispensible for pro
Industrial catalysts are often comprised of nanoparticles supported on high-surface-area oxides, in order to maximise the catalytically active surface area and thereby utilise the active material better. These nanoparticles expose steps and corners that, due to low coordination to neighboring atoms, are more reactive and, as a consequence, are often assumed to have higher catalytic activity. We ha
Previous research has expressed concerns about firms engaging less in basic research. We contribute to this debate by studying trends in the scientific publishing activities of firms located in Germany. Our results indicate that the firms’ aggregate volume of scientific publications stayed constant between 2008 and 2016. However, the number and share of publishing firms declined, and publication a
Although research indicates that single parenting is not by itself worse for children than their being brought up by both their parents, there are reasons why it is better for children to have more than one committed parent. If having two committed parents is better, everything else being equal, than having just one, I argue that it might be even better for children to have three committed parents
The article first rehearses three deflationary theories of reference, (1) disquotationalism, (2) propositionalism (Horwich), and (3) the anaphoric theory (Brandom), and raises a number of objections against them. It turns out that each corresponds to a closely related theory of truth, and that these are subject to analogous criticisms to a surprisingly high extent. I then present a theory of my ow
As a result of the project “A National Strategy for Standardisation of DigitalInformation Management within the Built Environment”, this report describes the framework of the strategy. The responsibility of the framework, maintenance and the update will be handled by the newly created Samhällsbyggandets Regelforum.Samhällsbyggandets Regelforum aims to contribute to the development of new and exist
We investigate the performance of linear consensus algorithms subject to a scaling of the underlying network size. Specifically, we model networked systems with nth order integrator dynamics over families of undirected, weighted graphs with bounded nodal degrees. In such networks, the algebraic connectivity affects convergence rates, sensitivity, and, for high-order consensus [n ≥ 3), stability pr
This paper shows the advantage of using both 3d models and surgical navigation system when preparing and planning complex brain surgery. The novel clinical process introduced here combine CT and MRI images in special computer program where the regions of interest are isolated e.g. the skull base, tumor and other soft tissue. A 3D model is calculated from the segmented m
