This article summarizes the processes that are responsible for cosmogenic radionuclide variations in ice cores and the results that can be inferred from these records. The article starts with the production in the atmosphere caused by the influx of galactic cosmic ray particles and its modulation by the solar and geomagnetic fields. Subsequently, the geochemical behavior of cosmogenic radionuclide
Ba3Si6O12N2:Eu2+ and Ba3Si6O9N4:Eu2+ have strikingly similar atomistic structures, but the former is an efficient green phosphor at working temperature while the latter is a bluish-green phosphor whose luminescence decreases quite fast with temperature. Aiming at the understanding of such different behavior, we compute the quasiparticle electronic band structure of the two hosts, Ba3Si6O 12N2 and
For a set of ten crystalline materials (oxides and semiconductors), we compute the electronic band structures using the Tran-Blaha (TB09) functional. The band widths and gaps are compared with those from the local-density approximation (LDA) functional, many-body perturbation theory (MBPT), and experiments. At the density-functional theory (DFT) level, TB09 leads to band gaps in much better agreem
Savannas are inherently “disturbed” ecosystems, but the regularly recurring disruptions play such a fundamental ecological role (Scholes and Archer, 1997) that “episodic events” rather than “disturbance” may the more apt terminology. From an atmospheric perspective, fire is the most significant of these episodic events. Fires shape community species composition; tree to grass ratio and nutrient re
We review some recent developments in many-body perturbation theory (MBPT) calculations that have enabled the study of interfaces and defects. Starting from the theoretical basis of MBPT, Hedin's equations are presented, leading to the GW and GWΓ approximations. We introduce the perturbative approach, that is the one most commonly used for obtaining quasiparticle (QP) energies. The practical strat
Carefully converged calculations are performed for the band gap of ZnO within many-body perturbation theory (G0W0 approximation). The results obtained using four different well-established plasmon-pole models are compared with those of explicit calculations without such models (the contour-deformation approach). This comparison shows that, surprisingly, plasmon-pole models depending on the f-sum r
We study the effects of self-consistency and vertex corrections on different GW-based approximations for model systems of interacting electrons. For dealing with the most general case, we use the Keldysh time-loop contour formalism to evaluate the single-particle Green's functions. We provide the formal extension of Hedin's GW equations for the Green's function in the Keldysh formalism. We show an

Translation Studies has crossed a tumultuous interval of theorization. But has it passed the linguistic limits instituted by a semiotician like Umberto Eco? Wouldn’t be the time to access more courageously the intersemiotic interregnum with its heterogeneous transfer of signs? As it happens in advertising, concrete poetry, tattoos, and stage or filmed version of famous texts? If we have gradually

Episoder utspelar sig i en vintrig småstad där gatljus speglar sig i den kalla snön och där människor befinner sig i rörelse; bort från andra och bort från sig själva. handlingen kretasar kring det möjliga och omöjliga i mötet med andra människor, om avgrunden mellan vad en människa är inför andra och vad hon är inför sig själv.Del 2 handlar om suget efter nåt att dricka och om ensamhet och om sjö
The aim with this paper is to examine how different GIS-based visualization methods can be applied and come to practical uses in the emergency service’s fire preventive work. These techniques motivate and facilitate various forms of fire prevention such as selection of areas or neighborhoods, blocks or buildings before home visits, identification and targeting of different risk groups and customiz
"Man's Desire to be God" is musical suite stretching from blues, rock, jazz to electronic music and classical music. Through particular performance methods in playing, singing, recording and producing the musical elements are blended together in a most mix. The concept and texts starts out from the sect around Charles Manson in the end of the 60s, out from where a story emerges that revolves aroun
Although there have been significant advances in the research field of critical infrastructures and vital societal functions during the last decade, there still exist many challenges in implementing and carrying out studies in practice. One of these challenges is a feasible method for mapping, analysing and visualising the cascading consequences that arise for critical infrastructures and societal
A ca 20 m thick succession of upper Furongian (Cambrian Stage 10) through Middle Ordovician (Darriwilian) strata exposed at Lanna, in the province of Närke, south-central Sweden, is described. The upper Furongian is represented by the Alum Shale Formation and reflects an overall shallowing trend that ultimately resulted in emergence above sea level and subaerial conditions. Hence, as in most other
The recently published Lethaia paper by Bergström et al. (https://doi.org/10.1111/let.12269) on the age of the Ordovician Winneshiek Shale (Iowa, USA), and the impact that formed the Decorah crater which hosts this rock unit, is an interesting scientific contribution, although there are a number of problems with the interpretations and data presentation that merit comment. Due mainly to a lack of
Critical infrastructures today are highly interdependent and increasingly important in providing services to the rest of the society. At the same time, each type of infrastructure requires specialised knowledge to design and manage. Therefore, to get a better understanding of how the infrastructures and the effect of interdependencies work as a whole, it is necessary to have an interdisciplinary a
Konsekvenser till följd av stora översvämningar och andra geografiskt utbredda händelser är ett återkommande fenomen världen över. Befolkningstäta områden med sammanflätade nätverk av kritiska infrastrukturer och samhällsviktiga verksamheter tillhör de mest drabbade. De komplexa beroendena mellan olika former av samhällsviktiga verksamheter kan leda till kaskadeffekter, därkonsekvenserna utifrån e
