Anion exchange membranes (AEMs) functionalized with certain alicyclic quaternary ammonium cations show high alkaline stability, which is necessary for use in fuel cells and water electrolyzers. Here, we have prepared and studied a series of poly(fluorene alkylene)s incorporating N,N-dimethylpiperidinium (DMP) and 6-azoniaspiro[5.5]undecane (ASU) cations in spirocyclic and bis-spirocyclic arrangeme

Research have shown that the correct integration of daylight and electric lighting reduces the energy use in buildings, while improving visual comfort. Smart shading systems, especially those electrically controlled, play an important role to control solar radiation. Similarly, smart and dimmable/tunable lighting can help to adjust the artificial light to the real users' needs. This paper presents

This paper presents basic data of the energy demand for district heating and plug loads logged by a building management system of an energy-efficient academic building located in Lund, Sweden. The data refers to the years 2019 and 2020 when occupancy varied significantly due to the Corona pandemic. The data shows that the building energy demand adapts poorly to fluctuating occupancy rates. With a

To ensure building construction with low heating demand, efficient use of sustainable energy carriers, and neutrality between heating technologies, Sweden recently introduced weighting factors (WFs) for different energy carriers which are now used in Energy Performance Certificates (EPCs). As EPC ratings are gaining increased influence in Swedish energy policy and regulation, with recent examples

SKINNY is a lightweight tweakable block cipher which received a great deal of cryptanalytic attention following its elegant structure and efficiency. Inspired by the SKINNY competitions, multiple attacks on it were reported in different settings (e.g. single vs. related-tweakey) using different techniques (impossible differentials, meet-in-the-middle, etc.). In this paper we revisit some of these

People with Parkinson’s disease (PwPD) have an increased risk for falls and near falls. They have particular difficulties with maintaining balance against an external perturbation, and several retropulsion tests exist. The Unified PD Rating Scale item 30 (UPDRS30) is the most common, involving an expected shoulder pull. Others recommend using an unexpected shoulder pull, e.g., the Nutt Retropulsio

Over the past decade, characteristic mode analysis (CMA) research has grown from a niche topic to a mainstream topic, warranting a tutorial-style special issue to survey the significant progress that has been made in this field. In thisintroductory article (PAPER 1), the focus is on providing the big picture. We start with a simple description of characteristic modes. Next, we examine the trends in

BACKGROUND: Remote assessment of respiratory tract infections (RTIs) has been a controversial topic during the fast development of private telemedicine providers in Swedish primary health care. The possibility to unburden the traditional care has been put against a questionable quality of care as well as risks of increased utilization and costs. The covid-19 pandemic has contributed to a changed m

Portugal's real income per head grew by a factor of eight during the second half of the twentieth century, a period of fast convergence towards Western European standards of living. We use a new sample of about 2,000 children to document trends in the prevalence of stunting and wasting in the city of Lisbon between 1945 and 1994. We find that stunting and wasting fell quickly in the 1950s and 1960

The pandemic-induced economic crisis has seen a massive build up in savings across Europe and North America as households could not spend their income as they normally would. The last time that consumers were seriously rationed was during the Second World War. This paper models the behaviour of households during the War years and its immediate aftermath in Ireland, Sweden, the US and the UK. We fi

Background & AimsYAP (Yap1) and TAZ (Wwtr1) are transcriptional co-activators and downstream effectors of the Hippo pathway, which play crucial roles in organ size control and cancer pathogenesis. Genetic deletion of YAP/TAZ has shown their critical importance for embryonic development of the heart, vasculature, and gastrointestinal mesenchyme. The aim of this study was to determine the functi

A low-profile wideband tri-polarized MIMO antenna is proposed in this paper. Based on characteristic mode analysis of a circular patch, four slots are etched symmetrically on the patch to transform the high-order monopole-like modes into broadside modes with lower resonant frequencies. Four sets of shorting pins are also applied to simultaneously adjust the resonant frequencies of the monopole-lik

This paper engages with the micro action of lifestyle enterprising from an interactionist perspective. The here-and-now action of enterprising is examined in the using the microsociology of Erving Goffman in a single observational case study of tourism lifestyle enterprising in Sweden. The findings illustrate the blurring of assorted personal and commercial domains in the performance of enterprisi
