It is shown that the equation of motion of the one-particle Green function of an interacting many-electron system is governed by a multiplicative time-dependent exchange-correlation potential, which is the Coulomb potential of a time-dependent exchange-correlation hole. This exchange-correlation hole fulfills a sum rule, a generalization of the well-known sum rule of the static exchange-correlatio

IntroductionSmall bowel obstruction, infertility, and chronic abdominal pain are generally mentioned as the main clinical consequences of adhesion formation after abdominal surgery1,2. Difficulties experienced during reoperation are less pronounced consequences, but seem to have a huge impact. A large retrospective cohort study3 revealed that adhesiolysis was significantly associated with risk of

Nanowires bring new possibilities to the field of hot-carrier photovoltaics by providing flexibility in combining materials for band engineering and using nanophotonic effects to control light absorption. Previously, an open-circuit voltage beyond the Shockley-Queisser limit was demonstrated in hot-carrier devices based on InAs-InP-InAs nanowire heterostructures. However, in these first experiment

Context. Wide hot subdwarf B (sdB) binaries with main-sequence companions are outcomes of stable mass transfer from evolved red giants. The orbits of these binaries show a strong correlation between their orbital periods and mass ratios. The origins of this correlation have, so far, been lacking a conclusive explanation. Aims. We aim to find a binary evolution model which can explain the observed

Aims: Preterm birth has been associated with elevated blood pressure early in life; however, hypertension risks from childhood into adulthood remain unclear. We conducted a large population-based study to examine gestational age at birth in relation to hypertension risks from childhood into adulthood. Methods and results: A national cohort study was conducted of all 4 193 069 singleton live births

Online learning has become an increasingly expected and popular component for education of the modern-day adult learner, including the medical provider. In light of the recent coronavirus pandemic, there has never been more urgency to establish opportunities for supplemental online learning. Heart University aims to be "the go-to online resource" for e-learning in CHD and paediatric-acquired heart

Atmospheric carbon dioxide enrichment (eCO2) can enhance plant carbon uptake and growth1–5, thereby providing an important negative feedback to climate change by slowing the rate of increase of the atmospheric CO2 concentration6. Although evidence gathered from young aggrading forests has generally indicated a strong CO2 fertilization effect on biomass growth3–5, it is unclear whether mature fores

Background: Extracorporeal membrane oxygenation (ECMO) is used in severe respiratory and/or circulatory failure when conventional critical care fails. Studies on patients with hematological malignancies on ECMO have shown contradictory results; immunosuppression and coagulopathy are relative contraindications to ECMO. Observations: This nationwide Swedish retrospective chart review identified 958

Introduction: Preeclampsia (PE) is a human specific pregnancy-related syndrome of unknown etiology that affects 2–8 % of pregnancies. Polymorphism in maternal Killer Cell Immunoglobulin-like Receptors (KIRs) and the ligand fetal Human Leukocyte Antigen-C (HLA-C) may predispose pregnant mothers for PE due to defective trophoblast invasion into the maternal decidua. Our study aimed to investigate th

This paper presents a measurement of the production cross-section of a Z boson in association with b-jets, in proton-proton collisions at s = 13 TeV with the ATLAS experiment at the Large Hadron Collider using data corresponding to an integrated luminosity of 35.6 fb−1. Inclusive and differential cross-sections are measured for events containing a Z boson decaying into electrons or muons and produ

The purpose of this paper is to increase our understanding of the governing of flood risk mitigation in advanced liberal society, through an in-depth Swedish case study. By combining social network analysis and genealogy, this paper investigates who is involved, how they organise, their modes of thinking, how they mitigate flood risk, as well as how such regime of practises have come into being. T

Growth in the smallholder-based livestock sector, characterized by increasing number of animals, commercialization and processing of animal products have historically provided a decisive contribution to raising the incomes of farm households, and to the broader process of agricultural transformation. In this paper, we use a mixed methods approach to examine the processes of extensive and intensive

Fires in waste facilities represent significant potential social, economic and environmental challenges. Although the awareness of fires in waste facilities and their consequences has increased in recent years, significant fire safety challenges remain. Fires in waste facilities in Norway and Sweden have been studied to make an overall fire safety assessment and propose measures for increased fire

A deeper knowledge of the architecture of the peripheral nerve with three-dimensional (3D) imaging of the nerve tissue at the sub-cellular scale may contribute to unravel the pathophysiology of neuropathy. Here we demonstrate the feasibility of X-ray phase contrast holographic nanotomography to enable 3D imaging of nerves at high resolution, while covering a relatively large tissue volume. We show

Based on the multiphase field conception and integrated with the idea of vector valued phase fields, a phase field model for typical allotropic transformation of solid solution is proposed. The model takes the non-uniform distribution of grain boundaries of the parent phase and the crystal orientation into account, as illustrated in simulations of austenite to ferrite transformation in low carbon Based on multiphase field conception and integrated with the idea of vectorvalued phase field, a phase field model for typical allotropic transformation of solid solution is proposed. The model takes the non-uniform distribution of grain boundaries of parent phase and crystal orientation into account in proper way, as being illustrated by the simulation of austenite to ferrite transformation in lo

Most adaptive controllers do not assume any a priori knowledge about the process to be controlled. In most situations there is, however, some knowledge about the process. This knowledge should be used to improve the performance compared to the “black box” approach of earlier adaptive controllers. The a priori knowledge is in this paper used in the estimation of the process and also in the design o

Background: Parents of young children are a vulnerable group with an increased risk of stress-related health problems compared to adults without children. Low occupational balance has been identified as a risk factor for stress-related disorders. Aim: The study aimed to describe occupational balance in parents of pre-school children and to explore potential differences between mothers and fathers.
