Massive MIMO (MaMI) is often promoted as a technology that will enable the use of low-quality, cheap hardware. One particular component that has been in the focus of MaMI-related research is the analog-to-digital converter (ADC), and use of very low-resolution ADCs has been proposed. However, studies about whether this strategy is justified from an energy-efficiency point of view have largely been
Issues surrounding relationships between different writings and questions regarding literary dependence are ubiquitous in New Testament scholarship. This study aims to answer questions concerning how one is to understand the way that early Christian writers used other Christian writings: Are any typical characteristics discernible regarding the earliest use of Christian writings? Were they memoriz
Aims This prospective study focuses on risk factors for arterial damage in children with type 1 diabetes (T1D). Methods Eighty children and adolescents with T1D were investigated twice, approximately 2 years apart, for carotid artery intima-media thickness (cIMT) and compliance (CAC), flow-mediated dilatation (FMD) of the brachial artery, and plasma levels of matrix metalloproteinase (MMP)-8. Al
Phosphorylation is a protein post-translational modification (PTM) that plays an important role in cell signaling, cell differentiation, and metabolism. The hyper phosphorylated forms of certain proteins have been appointed as biomarkers for neurodegenerative diseases, and phosphorylation-related mutations are important for detecting cancer pathways. Due to the low abundance of phosphorylated prot
Aims Screening for atrial fibrillation (AF) using intermittent electrocardiogram (ECG) recordings can identify individuals at risk of AF-related morbidity in particular stroke. We aimed to validate the performance of an AF screening algorithm compared with manual ECG analysis by specially trained nurses and physicians (gold standard) in 30 s intermittent one-lead ECG recordings. Methods and result
Previous studies on organic sediment contaminants focused mainly on a limited number of highly hydrophobic micropollutants accessible to gas chromatography using nonpolar, aprotic extraction solvents. The development of liquid chromatography–high-resolution mass spectrometry (LC–HRMS) permits the spectrum of analysis to be expanded to a wider range of more polar and ionic compounds present in sedi
Physiological adaptation through acclimation is one way to cope with temperature changes. Biochemical studies on acclimation responses in ectotherms have so far mainly investigated consequences of short-term acclimation at the adult stage and focussed on adaptive responses. Here, we assessed the consequences of rearing Drosophila melanogaster at low (12°C), benign (25°C) and high (31°C) temperatur
It is well known that nonirradiated cells can exhibit radiation damage (bystander effect), and recent findings have shown that nonirradiated cells may help protect irradiated cells (rescue effect). These findings call into question the traditional view of radiation response: cells cannot be envisioned as isolated units. Here, we investigated traditional colony formation assays to determine if they
The "habitat heterogeneity hypothesis" predicts positive effects of structural complexity on species coexistence. Increasing habitat heterogeneity can change the diversity (number of species, abundances) and the functional roles of communities. The latter, however, is not well understood as species and individuals may respond very differently and dynamically to a changing environment. Here, we exp
Popular Abstract in Swedish Avhandlingen handlar om litteraturläsning och litteraturundervisning i grundskolan. Syftet är att belysa den betydelse läsning av skönlitteratur ges i skolans mellanår i början av det tjugoförsta århundradet. Forskningsfrågorna berör de mål och föreställningar om litteratur och läsning som lärare ger uttryck för och hur dessa kommer till uttryck i konkret klassrumsarbetThis dissertation explores the teaching of literature in Swedish compulsory school. The aim of the study is to elucidate different approaches to literature instruction in upper elementary school (grades 4-6, pupils aged 10-13). The research questions focus on what goals and ideas about literature and reading guide teachers and how these are carried out in pedagogical practice and classroom activit
In a cross-sectional study of diabetic patients diagnosed at or after 30 years, and with different stages of retinopathy, factors such as duration of diabetes, treatment mode, metabolic control, blood pressure, and clinical signs of nephropathy were examined. The different stages of retinopathy used were absence of retinopathy, simplex, and severe retinopathy. Patients with simplex and severe reti
Background: Individuals belonging to the same family share a number of genetic as well as environmental circumstances that may condition a common SBP level. Among the genetic factors, the angiotensin converting enzyme (ACE) gene I/D polymorphism appears as a possible candidate as it might influence both SBP and the pharmacological effect of ACE inhibitors. We aimed to combine genetic epidemiology
Popular Abstract in Swedish ?Överbrygga det kommunikativa gapet mellan personer med en demenssjukdom och deras vårdare. Ett omvårdnadsperspektiv? En problematik i omvårdnaden av personer med långt framskriden demenssjukdom är hur vårdare skall tolka och förstå den demensdrabbade så att omvårdnaden kan anpassas till dennes behov. Forskning tyder på att vissa reaktioner, bland annat aggressiva handThe aim was to explore possible areas and sources that could inform the care for people with dementia. These were the people with dementia themselves, nurses reflective discussions about caring, nurse-patient interaction together with information from close family members, and the previous personality and sense of coherence of people with dementia in relation to behaviour during the disease as rel
This paper reviews current issues regarding short-term (i.e. for surgery and invasive procedures) and long-term (i.e. regular infusions to prevent bleeding on a permanent or temporary basis) prophylaxis treatment using replacement concentrates for patients with von Willebrand disease (VWD) who do not respond satisfactorily to desmopressin. The standard treatment of these patients is with factor co
PURPOSE:: The purpose of this research is 2-fold. First of all, the level of keratopathy development in patients with congenital aniridia is studied. In addition, a correlation between the effects of ocular surgery on the severity of keratopathy is made. METHODS:: A thorough search for the total number of patients with aniridia in Sweden and Norway was performed. One hundred eighty-one patients we
Density-dependent reproduction is commonly explained by either the habitat heterogeneity (HHH) or individual adjustment (IAH) hypothesis. Under the HHH, high quality territories are assumed to be occupied first. At higher density, occupation of low-quality territories increases due to lower availability of high-quality territories, which reduces mean reproductive success. Alternatively, the IAH as
Antibodies directed towards non-neutralizing epitopes on the factor VIII protein (FVIII) may be detected in patients with haemophilia A. We evaluated the prevalence of non-neutralizing antibodies, in 201 inhibitor-negative brother pairs with severe haemophilia A, enrolled in the Malmö International Brother Study and the Haemophilia Inhibitor Genetics Study. To evaluate binding specificity of the a
Germinal centers (GC) are well-defined areas in lymphoid organs were B cells proliferate and differentiate in response to T-cell-dependent antigens. The GC comprises B cells, follicular dendritic cells, tangible body macrophages, and a low number of CD4+ T cells. A large portion of these T cells expresses CD57. We have examined the ability of the CD4+CD57+ GC T cells to become activated and to tak
High-resolution core-level photoemission is used to study structural aspects for the molecular adsorption of CO on the Rh(111) single-crystal surface, and in particular to derive the adsorption sites. The site sensitivity of the core-level binding energy and the fact that the core level photoemission signal is proportional to the adsorbate coverage make it possible to study quantitatively how the
The rapid advances in life science, including the sequencing of the human genome and numerous other techiques, has given an extraordinary ability to aquire data on biological systems and human disease. Even so, drug development costs are higher than ever, while the rate of new approved treatments is historically low. A potential explanation to this discrepancy might be the difficulty of understand
