We study how the k dependence in the self-energy affects the quasiparticle band structure and one-particle spectral functions. It is known that, in electron-gas-like materials, the self-energy depends significantly on k and there is a strong cancellation between the k dependence and the energy dependence of the self-energy. Analysis of the GW self-energy reveals that, even in correlated materials

Climate change mitigation and energy security are partly interacting areas that both present future challenges. The extensive research underway within these areas is mainly conducted in separate research communities, although there are some integrative efforts. This paper examines the breadth and heterogeneity involved in treating energy security and climate change mitigation as a combined researc
Det nya handboksförslaget granskas med avseende på språk och stil och med avseende på strukturen i gudstjänsten. Flera kritiska synpunkter på språk och stil ges, och placeringen av syndabekännelsen i gudstjänstens inledning liksom placeringen av förbönen mellan predikan och nattvard kritiseras, detta med utgångspunkt från hermeneutiska insikter, och från dramaturgisk analys.
Axonal outgrowth on smooth and porous silicon surfaces was studied in organ culture. The pore size of the silicon substrata varied between 100 and 1500 nm. We found that axons preferred to grow and elongate on porous silicon surfaces only when pores of (150-500 nm) are available.
Low molecular weight heparins (LMWH's) are used to prevent and treat thrombosis. Tests for monitoring LMWH's include anti-factor Xa (anti-FXa), activated partial thromboplastin time (aPTT) and thrombin generation. Anti-FXa is the current gold standard despite LMWH's varying affinities for FXa and thrombin.
Popular Abstract in Swedish Denna avhandling syftar till att föreslå, utvärdera och applicera testprocedurer för rationalitet, svag separabilitet och effektivitet. Främst behandlas icke-parametriska så kallade ’revealed preference’ procedurer, vilka har fördelen att de, till skillnad från den parametriska ansatsen, inte behöver anslå någon funktionell form för nyttofunktionen. En majoritet av de tThis thesis aims to propose, evaluate and apply test procedures for rationality, weak separability and efficiency. In particular, it focuses on nonparametric revealed preference procedures. This approach has the advantage of not having to stipulate any functional form for the utility function, unlike the parametric approach which relies on finding a suitable functional form for the utility functio
Sophisticated statistical analyses are common in ecological research, particularly in species distribution modeling. The effects of sometimes arbitrary decisions during the modeling procedure on the final outcome are difficult to assess, and to date are largely unexplored. We conducted an analysis quantifying the contribution of uncertainty in each step during the model-building sequence to variat
The herbaceous understory forms the richest stratum in temperate broadleaved forests in terms of plant diversity. Understanding the process of understory succession is thus of critical importance for the development of management guidelines for biodiversity restoration in post-agricultural plantation forests. We studied effects of stand age, forest fragmentation, and soil and canopy conditions on
A key aspect of leadership is the followers’ constructions of its value and relevance. Based on two empirical, qualitative case studies, this paper highlights the importance of the ‘demand’ for leadership when leader–follower relationships are established. We further discuss how followers influence, inhibit and initiate managerial leadership (i.e. leadership acts from their formal superior targeti
Background: This contribution deals with chemical processes at the biological membranes of endothelial cells in blood vessels. A basic observation is that the intensity of blood flow navigates the vascular width through a negative feedback circle. When the blood flow increases, the vessels become wider; when it decreases the vascular smooth muscle cells contract. The anionic polyelectrolyte hepara

Steven Spielberg's film Saving Private Ryan is at the centre of this text, with a particular focus on how it displays the past in ways that place the audience in the middle of the historical action. By looking at various technical breakthroughs predating this film, it is argued that what we here see is the beginning of a new kind of 360-degree historiography that nowadays dominates historical epic
We discuss general non-stationary spatio-temporal surfaces that involve dynamics governed by velocity fields. The approach formalizes and expands previously used models in analysis of satellite data of significant wave heights. We start with homogeneous spatial fields. By applying an extension of the standard moving average construction we obtain models which are stationary in time. The resulting
BackgroundA common genetic variant (rs10993994) in the 5' region of the gene encoding β-microseminoprotein (MSP) is associated with circulating levels of MSP and prostate cancer risk. Whether MSP levels are predictive of prostate cancer risk has not been evaluated.MethodsWe investigated the prospective relationship between circulating plasma levels of MSP and prostate cancer risk in a nested case-
Treatment of [Fe-3(CO)(12)] with tri(2-furyl)phosphine (PFu(3)) or tri(2-thienyl)phosphine (PTh3) in dichloromethane at 40 degrees C leads to facile phosphorus carbon bond scission affording di-iron furyl- and thienyl-bridged complexes [Fe-2(CO)(6)(mu-eta(1),eta(2)-C4H3E)(mu-P(C4H3E)(2))] (1 E = O, Fu; 3 E = S, Th) in good yields, together with smaller amounts of the phosphine-substituted [Fe-2(CO
Young exocrine pancreas insufficient (EPI) pigs given a commercial feed (polymeric diet) show growth retardation that can be reversed by dietary supplementation with pancreatic enzymes. Our aim was to investigate if providing an elemental diet, mimicking a pre-digested diet, can support body growth in EPI-pigs. Thus, EPI-pigs, pancreatic duct-ligated at 12.2 +/- 2.6 weeks of age (15.3 +/- 4.8 kg),
We report the discovery of ferroelectricity below 4.5 K in highly underdoped La2CuO4+x accompanied by slow charge dynamics which develop below T similar to 40 K. An anisotropic magnetoelectric response has also been observed, indicating considerable spin-charge coupling in this lightly doped parent high-temperature copper-oxide superconductor. The ferroelectric state is proposed to develop from po
