To receive support from social services in one’s own home is a major life course transition for the client in need of help. But this is also a life changing transition for cohabitating partners, whose home is transformed to a workplace where staff come and go. Partners' perspectives have received a lot of attention in social work, but almost exclusively based on their relationship with the primary
Pancreatic islet hormones regulate blood glucose homeostasis. Changes in blood glucose induce oscillations of cytosolic calcium in pancreatic islet cells that trigger secretion of three main hormones: insulin (from β-cells), glucagon (α-cells) and somatostatin (δ-cells). β-Cells, which make up the majority of islet cells and are electrically coupled to each other, respond to the glucose stimulus a
Car prevalence in society has a negative effect on both local and global environments. One way to tackle these problems is to restrict car traffic in city centres, this comes not only with effects on the environment. How car free zones can affect retail in cities is examined in this study. The study takes place in ten retail shops in the city centre of Lund along three streets. Customers are aske
Time-domain induced polarization (TDIP) data carry spectral information that can be used for petrophysical interpretation. At the same time, TDIP data can be collected in the field more efficiently than frequency-domain induced polarization (FDIP) data, thanks to the use of square-wave signals. However, TDIP field data are prone to noise, particularly strong near industrial installations and urban

‘Is there life on exoplanets?’. We refer to exoplanets as planets in other solar systems than our own. This often asked question can be further refined by asking ‘is there life on exoplanets which is so extensive that it may impact on its atmosphere, its biosphere and its optical properties?’. And if such a life exists, at astronomical distances from us, can we detect it with instruments on Earth-
Cooperative transmission by base stations (BSs) can significantly improve the spectral efficiency of multiuser, multicell, multiple input multiple output (MIMO) systems. We show that contrary to what is often assumed in the literature, the multiuser interference in such systems is fundamentally asynchronous. Intuitively, perfect timing-advance mechanisms can at best only ensure that the desired si
Deep metabarcoding offers an efficient and reproducible approach to biodiversity monitoring, but noisy data and incomplete reference databases challenge accurate diversity estimation and taxonomic annotation. Here, we introduce a novel algorithm, NEEAT, for removing spurious operational taxonomic units (OTUs) originating from nuclear-embedded mitochondrial DNA sequences (NUMTs) or sequencing error
The aim of this paper is to explore the establishment of diplomatic representation as a measure of de facto recognition by other state units, and to explain its causes in the “long 19th century” (1817-1914). The premise of the paper is that, at least before the advent of broad-ranging legitimizing international organizations such as the League of Nations or the UN in the 20th century, sending a di
Subband adaptive filters have been proposed to speed up the convergence and to lower the computational complexity of time domain adaptive filters. However, subband processing causes signal degradations due to aliasing effects and amplitude distortions. This problem is unavoidable due to further filtering operations in subbands. In this paper, the problem of aliasing effect and amplitude distortion
A novel low-complexity detection scheme is proposed for the multiple-input multiple-output (MIMO) single-carrier frequency division-multiple access (SC-FDMA) systems, which is suitable for ASIC implementations. The proposed detection scheme makes an initial estimate of the transmitted signal based on a minimum mean square error (MMSE) frequency domain equalizer (FDE) detector and finds symbols wit
Early and accurate diagnosis of intestinal ischemia is important in order to provide rapid and correct treatment and reduce morbidity and mortality rates. Clinical signs and symptoms are often unspecific. This systemic review sums up literature regarding human plasma biomarkers for acute mesenteric ischemia reported during the last ten years. Classic, general markers, including lactate, white cell
The determination of the CP nature of the Higgs coupling to top quarks is addressed in this paper, using tt-h events produced in s=13 TeV proton-proton collisions at the LHC. Dileptonic final states are employed, with two oppositely charged leptons and four jets, corresponding to the decays t→bW+→b+ν, t-→b-W-→b--ν-, and h→bb-. Pure scalar (h=H), pure pseudoscalar (h=A), and CP-violating Higgs boso
The problem of classifying short atrial fibrillatory segments in ambulatory ECG recordings as being either paroxysmal or persistent is addressed by investigating a robust approach to signal characterization. The method comprises preprocessing, estimation of the dominant atrial frequency for the purpose of controlling the subbands of a filter bank, and computation of the relative subband (harmonics

Medlemsbrev från ordföranden 201904 Medlemsbrev från ordföranden (English version below) Hej! Nu verkar våren ha tagit ett grepp om vår vackra stad och vad passar väl bättre än en uppdatering av vad som händer på Saco-S förhandlingsområden. • RALS-2018 har avslutats i oenighet eftersom parterna inte lyckats nå en överenskommelse. Detta betyder att alla som varit oeniga får vänta lite till på sina
In previous work we have demonstrated increased expression of NOX2 in cardiomyocytes of infarcted human hearts. In the present manuscript we investigated the functional role of NOX2 in ischemically challenged H9c2 cells, a rat cardiomyoblast cell line, and adult rat cardiomyocytes. Expression of NOX2 in H9c2 cells was confirmed by RT-PCR. In Western-blot experiments, increased NOX2 expression was
