An ensemble Green's function formalism, based on the von Neumann density matrix approach, to calculate one-electron excitation spectra of a many-electron system with degenerate ground states is proposed. A set of iterative equations for the ensemble Green's function and self-energy is derived and a simplest approximation corresponding to an ensemble GW approximation is naturally obtained. The deri

The addition of polyelectrolytes (PEs) to suspensions of charged colloids, such as nanoplatelets (NPs), is of great interest due to their specific feature of being either a stabilizing or a destabilizing agent. Here, the complexation between a PE and oppositely charged NPs is studied utilizing coarse-grained molecular dynamics simulations based on the continuum model. The complex formation is eval

Identifying the environmental factors that shape intraspecific genetic and phenotypic diversity of species can provide insights into the processes that generate and maintain divergence in highly diverse biomes such as the savannas of the Neotropics. Here, we sampled Qualea grandiflora, the most widely distributed tree species in the Cerrado, a large Neotropical savanna. We analyzed genetic variati

Biofilm has been implicated as a barrier to wound healing and it is widely accepted that the majority of wounds not following a normal healing trajectory contain biofilm. Therefore, strategies that inform and engage clinicians to reduce biofilm and optimise the wound tissue environment to enable wound progression are of interest to wound care providers. In March 2019, an advisory board was convene

Aims To investigate practice effects in a test-retest situation, where vibration perception thresholds (VPT) were measured in healthy subjects using a multi-frequency test method. Methods In eight consecutive tests, VPTs were tested in the pulps of the index and little fingers at seven frequencies (8, 16, 32, 64, 125, 250 and 500 Hz). Subjects were twenty healthy adults aged 26 to 65 years (mean 4

Small-angle scattering of X-rays and neutrons is a routine method for the determination of nanoparticle sizes. The so-called Guinier law represents the low-q approximation for the small-angle scattering curve from an assembly of particles. The Guinier law has originally been derived for nonmagnetic particle-matrix-type systems and it is successfully employed for the estimation of particle sizes in

In this paper, a unique event is studied: the opening of Bank of Canada in 1935, the central bank note issuance monopoly and its impact on the note issuing chartered banks. Between 1935-1950, Canadian chartered banks had to gradually withdraw their notes from circulation. In a difference-in-differences analysis, I show that chartered banks constrained by new issuance limits experienced higher vola

What determines inequality and mobility of wealth? This paper quantifies in closed form both the bottom and the top (Pareto) tail of the distribution for a rich continuous-time model. The distribution is especially shaped by bequest motives, demographics, and the asset portfolio composition under idiosyncratic wealth risk. Factors that increase inequality also reduce mobility. The model - enriched

A plant bioassay was used to enumerate infectious Frankia in soil and micro- and molecular techniques were used to identify possible mechanisms by which Frankia survive drying.Myrica-nodulating Frankia occurred in five Hawaiian volcanic deposits with depositional ages ranging from 20 to 162 years before present. The oldest deposit had a mean estimated nodulation capacity from 450 to 1200 times gre

The Uppsala university coin cabinet harbours arather unusual numismatic treasure, a ‘screw-thaler’ from Augsburg, produced in the secondhalf of the 17th century. The object combines twothalers from Augsburg, one from 1632 portrayingthe Swedish king Gustavus Adolphus, and theother one coined 1658 displaying the city ofAugsburg. One side of both coins is polished aswell as hollowed out, and the rim

Om tidigmodern ärekränkande svensk och dansk begravningspoesi, med utgångspunkt i Christina Holst Færchs stuide Smædeskrifter, sladder og erotiske vers i 1700-tallet. Hans Nordrups forfatterskab, København 2019.

Experimental studies have suggested an atheroprotective role of interleukin (IL)-5 through the stimulation of natural immunoglobulin M antibody expression. In the present study we show that there are no associations between baseline levels of IL-5 and risk for development of coronary events or stroke during a 15.7 ± 6.3 years follow-up of 696 subjects randomly sampled from the Malmö Diet and Cance

In recent years, several Swedish companies have been accused in the media, by NGOs, and via legal proceedings of engaging in criminal activities. Two of these companies, TeliaSonera and Lundin Petroleum have been the focus of substantial public attention. During the years following the revelations that TeliaSonera, a partly state owned telecommunications company, had committed bribery offences in

In comparison to other human cancer types, malignant melanoma exhibits the greatest amount of heterogeneity. After DNA-based detection of the BRAF V600E mutation in melanoma patients, targeted inhibitor treatment is the current recommendation. This approach, however, does not take the abundance of the therapeutic target, i.e., the B-raf V600E protein, into consideration. As shown by immunohistoche

Upprinnelsen till detta specialnummer är frågan om hur dagens forskning om läsning och skrivning kan möta framtidens behov av undervisning för individen och i klassrummet. Både läsning och skrivning är komplexa aktiviteter, och för att vi till fullo ska förstå dem och kunna bidra till utveckling av skolans praktiker krävs att kunskaper från (ett antal) olika forskningsfält integreras.

Heart failure (HF) is a major public health problem characterized by inability of the heart to maintain sufficient output of blood. The systematic characterization of circulating proteins across different stages of HF may provide pathophysiological insights and identify therapeutic targets. Here we report application of aptamer-based proteomics to identify proteins associated with prospective HF i

We evaluated the performance of CSF biomarkers for predicting risk of clinical decline and conversion to dementia in non-demented patients with cognitive symptoms. CSF samples from patients in two multicentre longitudinal studies (ADNI, n = 619; BioFINDER, n = 431) were analysed. Aβ(1–42), tTau and pTau CSF concentrations were measured using Elecsys CSF immunoassays, and tTau/Aβ(1–42) and pTau/Aβ(

The last decade has seen a range of studies using non-invasive neutron and X-ray techniques to probe the ultrastructure of a variety of photosynthetic membrane systems. A common denominator in this work is the lack of an explicitly formulated underlying structural model, ultimately leading to ambiguity in the data interpretation. Here we formulate and implement a full mathematical model of the sca
