Attosecond transient absorption spectroscopy (ATAS) allows for the study of electron dynamics in atoms and molecules with attosecond time resolution. Previous works reported in the literature have made use of ATAS to image and control such dynamics in the single-channel ionization continuum of helium; in particular, in the vicinity of the doubly excited autoionizing states lying between the N=1and
I Arktis er en klimakjempe i ferd med å våkne sakte, men sikkert fra sin lange dvale: Permafrosten – grunn som kan ha vært frosset i tusenvis av år – begynner flere steder å tine på grunn av de sterkt økende temperaturene (Box m.fl. 2019). Dette kan gjøre klimaproblemet enda verre enn det allerede er, fordi det kan føre til store utslipp av drivhusgasser som CO2 og metan (CH4). Når det skjer, varm
Smart cities promise to generate economic, social and environmental value through the seamless connection of urban services and infrastructure by digital technologies (Hollands 2008, Viitanen and Kingston 2014), but there is scant evidence concerning their ability to enhance social well-being, build just and equitable communities, reduce resource consumption and waste generation, improve environme
How do crisis perceptions interrelate with the emergence and re-constitution of policy problems? By using a novel combination of interviews with a content and network analysis of hand-coded parliamentary questions, this article maps the emergence of brain drain as a policy problem at the level of the European Union and follows the evolution of the issue over the last four parliamentary periods (fr
In this article, Giorgio Agamben's essay Pilate and Jesus and in particular its notion of suspension as stalemate is treated as an important contribution to an ongoing exegetical conversation about the theological valence and event of John 18:28.19:41. In Agamben's essay, the suspension created by the dialogue between the Christ and the "Vicar of Caesar" demonstrates a peculiar stalemate of immane
A large literature emphasizes that elite capture of political institutions hampered the spread of mass schooling in the nineteenth and twentieth century. We collect new data on investments in elementary education and the distribution of voting rights for more than 2,000 local governments in nineteenth‐century Sweden and document that educational expenditure was higher where the distribution of pol
Maternally inherited parasites are known to impose a wide variety of reproductive manipulations upon their host. These often produce strong selection on the host to suppress the parasite, resulting in a reduction in the frequency of the parasite. However, in the butterfly Hypolimnas bolina, infected with a Wolbachia bacterium, field data demonstrate that suppression of the male-killing phenotype d
The marine environment harbors a large proportion of the total biodiversity on this planet, including the majority of the earths’ different phyla and classes. Studying the genomes of marine organisms can bring interesting insights into genome evolution. Today, almost all marine organismal groups are understudied with respect to their genomes. One potential reason is that extraction of high-quality
Using the LiDAR-derived Swedish national height model we have identified previously undescribed shallow streamlined glacial bedforms, small-scale drumlins, on the Närke plain in south-central Sweden. These drumlins could only be detected with high-resolution LiDAR, due to both their subtle size and forest cover. In this area the ice margin receded in a subaqueous environment with a proglacial wate
Hox genes orchestrate development by patterning the embryonic axis. Vertebrate Hox genes are arranged in four compact clusters, and the spacing between genes is assumed to be crucial for their function. The genomes of squamate reptiles are unusually rich and variable in transposable elements (TEs), and it has been suggested that TE invasion is responsible for the Hox cluster expansion seen in snak
The Copenhagen Food Coop (CFC) is an alternative food community in Copenhagen that provides locally grown organic vegetables and fruits to its members. It also disseminates knowledge on organic and sustainable food production, distribution, and consumption and aims to develop a participatory and inclusive community organisation. Some scholars see such alternative food networks as having great pote
Amyloid fibrils of α-synuclein (α-syn) are a component of Lewy bodies, the characteristic hallmark of Parkinson's disease. Amyloid fibrils arise through primary nucleation from monomers, which in the case of α-syn is often heterogeneous, followed by the growth of the nuclei by monomer addition. Secondary nucleation corresponds to the formation of new fibrils facilitated by pre-existing fibrils. Wh
We report on the influence of doping on the band-edge abruptness of InAs/GaSb p-n and p-i-n tunnel diodes. Understanding and fabrication of a well-defined and sharp band edge is mandatory for tunnel FET operation. InAs/GaSb nanowire junctions were selectively grown by metal organic chemical vapor deposition (MOCVD) on silicon-on-insulator (SOI) substrates using template assisted selective epitaxy
Human intrahepatic lymphocytes are enriched in CD1d-unrestricted T cells coexpressing NKR. Although the origin of this population remains controversial, it is possible to speculate that the hepatic microenvironment, namely epithelial cells or the cytokine milieu, may play a role in its shaping. IL-15 is constitutively expressed in the liver and has a key role in activation and survival of innate a
The transcriptional events that control T cell tolerance are still poorly understood. To investigate why tolerant T cells fail to produce interleukin (IL)-2, we analyzed the regulation of NFkappaB-mediated transcription in CD4(+) T cells after tolerance induction in vivo. We demonstrate that a predominance of p50-p50 homodimers binding to the IL-2 promoter kappaB site in tolerant T cells correlate
How can we reconcile the conception of language as a conventional-normative semiotic system with a perception/action-based account of its structure and meaning? And why should linguistic meaning - as opposed to linguistic expression - be so closely related to motor activity and its neural underpinnings, as suggested by recent findings? A conceptual framework and evolutionary scenario building on t
