Infant outcome after active management of early-onset fetal growth restriction with absent or reversed umbilical artery blood flow

Objective: To describe the short- and long-term outcomes of infants with early-onset fetal growth restriction (FGR) and umbilical artery absent or reversed end-diastolic flow (AREDF), delivered before 30 weeks' gestation and managed proactively. Methods: This was a retrospective cohort study of fetuses delivered for fetal indication before 30 completed weeks' gestation that had early-onset FGR (de

Reconfiguring work and organizing for post-pandemic futures

Across the world, the pandemic has made many of us rapidly change (at least temporarily) how we organize, work, and live, provoking a series of urgent questions. What is our relationship with the family, community, environment and the state? How should we structure our work? How do we value essential work and workers? How are we going to live, work, and organize differently in a post-pandemic worl

Sequential Infiltration Synthesis into Maltoheptaose and Poly(styrene): Implications for Sub-10 nm Pattern Transfer

Vapor phase infiltration into a self-assembled block copolymer (BCP) to create a hybrid material in one of the constituent blocks can enhance the etch selectivity for pattern transfer. Mul- tiple pulse infiltration into carbohydrate-based high-χ BCP has previously been shown to enable sub-10 nm feature pattern transfer. By optimizing the amount of infiltrated material, the etch selectiv- ity shoul

Efficient downlink power allocation algorithms for cell-free massive mimo systems

Cell-free Massive MIMO systems consist of a large number of geographically distributed access points (APs) that serve the users by coherent joint transmission. The spectral efficiency (SE) achieved by each user depends on the power allocation: which APs that transmit to which users and with what power. In this article, we revisit the max-min and sum-SE power allocation policies, which have previou

Towards Fully Dynamic Surface Illumination in Real-Time Rendering using Acceleration Data Structures

The improvements in GPU hardware, including hardware-accelerated ray tracing, and the push for fully dynamic realistic-looking video games, has been driving more research in the use of ray tracing in real-time applications. The work described in this thesis covers multiple aspects such as optimisations, adapting existing offline methods to real-time constraints, and adding effects which were hard

Depressive symptoms during pregnancy and after birth in women living in Sweden who received treatments for fear of birth

The aim of this study was to investigate the prevalence of depressive symptoms and associated factors in women who underwent treatments for fear of birth; internet-based cognitive therapy, counseling with midwives, continuity with a known midwife or standard care. A secondary analysis was performed using data collected from four samples of women identified with fear of birth and receiving treatmen

Type 1 diabetes, cognitive ability and incidence of cardiovascular disease and death over 60 years of follow-up time in men

AIMS: There are few cohorts of type 1 diabetes that follow individuals over more than half a century in terms of health outcomes. The aim of this study was to examine associations between type 1 diabetes, diagnosed before age 18, and long-term morbidity and mortality, and to investigate whether cognitive ability plays a role in long-term morbidity and mortality risk.METHODS: In a Swedish cohort, 1

Quantification of the absorption and scattering effects of diffusers in a room with absorbent ceiling

In ordinary public rooms, such as classrooms and offices, an absorbent ceiling is the typical first acoustic action. This treatment provides a good acoustic baseline. However, an improvement of specific room acoustic parameters, operating for specific frequencies, can be needed. It has been seen that diffusing elements can be effective additional treatment. In order to choose the right design, pla

Helsingborg – var fanns den äldsta staden? : Myten om högstaden och urbaniseringen

Already in the 16th century, archbishop Mogens Madsen described the area around the castle on the steep escarpment overlooking the narrowest strait in Öresund, as a vanished Troy. The historian Ludvig Magnus Bååth, who wrote the first academic work on the history of Helsingborg, promoted this narrative of an original urban settlement on the top of the escarpment. The paramount argument for an urba

60 fs, 1030 nm FEL pump-probe laser based on a multi-pass post-compressed Yb:YAG source

This paper reports on nonlinear spectral broadening of 1.1 ps pulses in a gas-filled multi-pass cell to generate sub-100 fs optical pulses at 1030 nm and 515 nm at pulse energies of 0.8 mJ and 225 μJ, respectively, for pump-probe experiments at the free-electron laser FLASH. Combining a 100 kHz Yb:YAG laser with 180 W in-burst average power and a post-compression platform enables reaching simultan

Adaptive doping of spatially coupled LDPC codes

In this paper, we study the problem of error propagation in sliding window decoding (SWD) of spatially coupled LDPC (SC-LDPC) codes. A general decoder model that accounts for error propagation is proposed and analyzed, and the decoded block error rate (BLER) is calculated using the model. In order to improve the BLER performance under decoder error propagation conditions, adaptive variable node (V

Uanset hvilken målestok man bruger for en retfærdig fordeling af det globale klimabudget må man konstatere, at den danske klimapolitik er langt fra tilstrækkelig ambitiøs.

Healthcare costs of dementia diseases before, during and after diagnosis : Longitudinal analysis of 17 years of Swedish register data

Introduction: This study examines health-care costs attributed to dementia diseases in the 10 years prior to, during, and 6 years after diagnosis. Methods: Using administrative register data for people diagnosed with dementia (2010–2016) in southern Sweden (n = 21,184), and a comparison group without dementia, health-care costs over 17 years were examined using longitudinal regression analysis. Re

Two-stage reflective self-seeding scheme for high-repetition-rate X-ray free-electron lasers

X-ray free-electron lasers (XFELs) open a new era of X-ray based research by generating extremely intense X-ray flashes. To further improve the spectrum brightness, a self-seeding FEL scheme has been developed and demonstrated experimentally. As the next step, new-generation FELs with high repetition rates are being designed, built and commissioned around the world. A high repetition rate would si

A review of ichthyosaur (Reptilia, Ichthyopterygia) soft tissues with implications for life reconstructions

The dolphin-like ichthyosaurs – also known as ‘fish lizards’ – are extinct marine reptiles that roamed the Mesozoic oceans for some 160 million years. As for most ancient vertebrates, our knowledge of these iconic animals largely derives from biomineralized hard parts (teeth and bones). However, soft tissues are also known from a number of Lagerstätte specimens, and have opened up new avenues for
