The overall system performance of massive MIMO is improved by equipping user terminals with multiple antennas. In this paper, we investigate transceiver designs for the case of a single downlink stream and in particular, we study the uplink pilot design. Moreover, we study the consequences of channel estimation errors at the base-station, and to what extent a dual-antenna terminal can get access t

In this work, we introduce an antenna placement algorithm for indoor radio networks. The algorithm aims to minimize the number of antennas required to provide sufficient coverage in an area of interest, minimizing the cost of equipment and installation work. The optimization algorithm exploits a semi-deterministic model for the most dominant radio paths. Each path is in turn determined with the A∗

A search for the bb decay of the Standard Model Higgs boson produced through vector-boson fusion is presented. Three mutually exclusive channels are considered: two all-hadronic channels and a photon-associated channel. Results are reported from the analysis of up to 30.6 fb-1 of pp data at s=13 TeV collected with the ATLAS detector at the LHC. The measured signal strength relative to the Standard

Rising global sea level caused by melting ice sheets poses a major challenge in a persistently warming climate. The Greenland Ice Sheet (GrIS) is among the main contributors, and in order to make accurate predictions of future ice retreat and sea level rise, it is imperative to understand how the ice sheet responded to global warming in the past. Reconstructions of relative sea level (RSL) are a k

When humans plan for the future, we recognize not only that one particular event may occur, but that the future can have different, mutually exclusive possible outcomes. A recent study by Suddendorf et al. (Suddendorf 2017 Biol. Lett. 13, 20170170 (doi:10.1098/rsbl.2017.0170)) suggests that young children (less than 3 years) and apes lack this capacity, as demonstrated by their failure to cover ea

Chronic liver disease (CLD) is frequently seen in the hemophilia population. The ADVANCE Working Group conducted a cross-sectional study in which people with hemophilia (PWH) aged ≥40 years were included. This study aimed to assess the associations between CLD and its risk factors using data from the H3 study, and to suggest implications for optimal care.Data from 13 European countries were collec

With origins in post-war development thinking, the core-periphery concept has spread across the social and, increasingly, the natural sciences. Initially reflecting divergent socioeconomic properties of geographical regions, its relational connotations rapidly led to more topological interpretations. In today's network science, the standard core-periphery model consists of a cohesive set of core a

The present paper aims to analyze the applicability of film cooling method to a rocket as a thermal protection. Lateral curvature effect on film cooling performance through a single row of cylindrical holes with different spanwise angles is investigated. Four different lateral curvature cases (C = ∞, 100, 60, 20) with four inclination angles of cooling injection holes (β= 35°, 45°, 55°, 65°) are c

Congenital muscular dystrophy with laminin α2 chain-deficiency (LAMA2-CMD) is a severe muscle disorder with complex underlying pathogenesis. We have previously employed profiling techniques to elucidate molecular patterns and demonstrated significant metabolic impairment in skeletal muscle from LAMA2-CMD patients and mouse models. Thus, we hypothesize that skeletal muscle metabolism may be a promi

This article reports the results of a survey focusing on the educational context of second foreign languages (SFL) to which 147 Swedish secondary school leaders responded. The study aims to provide a picture of how SFLs like German, French and Spanish are organised in a representative selection of Swedish schools across the country. The results of the survey show that there are major differences b

RESEARCH DESIGN AND METHODS: We studied participants in PROVALID (PROspective cohort study in patients with type 2 diabetes mellitus for VALIDation of biomarkers), a prospective multinational cohort study of patients with type 2 diabetes and a follow-up of more than 24 months (n = 2,560; baseline median eGFR, 84 mL/min/1.73 m2; urine albumin-to-creatinine ratio, 8.1 mg/g). The 17 biomarkers were m

Background: Helping consumers make healthier food choices is a key issue for the prevention of cancer and other diseases. In many countries, political authorities are considering the implementation of a simplified labelling system to reflect the nutritional quality of food products. The Nutri-Score, a five-colour nutrition label, is derived from the Nutrient Profiling System of the British Food St

The aim of this article is to problematize tourism enterprising fishermen ́s understanding of nature. From a discourse-theoretic outlook, I explore how fishermen “know” nature. Here, “knowing nature” is a positioning practice which means that views of nature are uttered and negotiated by people in relation to another person or a group of people. The empirical material that is analyzed was created

Comments are given on the identity of some populations of allotetraploid Dactylorhiza in southern Norway and their relationships to populations elsewhere in Scandinavia and in continental Europe. The most widespread allotetraploid member of Dactylorhiza in southern Norway is D. majalis ssp. sphagnicola. This subspecies is confined to poor and medium-rich fens dominated by peat mosses, Sphagnum, inComments are given on the identity of some populations of allotetraploid Dactylorhiza in southern Norway and their relationships to populations elsewhere in Scandinavia and in continental Europe.

En eftermiddag i juli 2011 besökte jag yrkesfiskaren Nils i hamnen. Vi talade länge om hur han kommit att börja med yrkesfiske och om hans dröm som nyligen blivit verklighet, att sälja fångsten från en egen fiskvagn i hamnen. Han hade även många idéer om hur fisket kunde utvecklas samtidigt som framtidsbilden var dystopisk. I en ekonomi där yrkesfisket har minskat med åttio procent på nittio år, m

Despite morphological divergence, the two orchid genera Gymnadenia andNigritella are closely related and hybrids are often encountered at places wheremembers of the two genera grow together. On basis of pollination studies, it hasbeen suggested that members of Nigritella should have served as pollen parent tothese hybrids. Hybridization does not go beyond primary hybrid formation, butone of the hy

The orchid Coeloglossum viride (L.) Hartm. has a circumboreal distribution and is widespread in the Nordic countries, especially in the boreal and montane regions. Whereas plants from the lowlands are generally slender and have greenish-yellowish flowers, plants from mountain areas tend to be low-growing with fewer, reddish-brown flowers, leading some authors to recognize the latter as a separate The orchid Coeloglossum viride (L.)

Back pain is the #1 cause of years lived with disability worldwide, yet surprisingly little is known regarding the biology underlying this symptom. We conducted a genome-wide association study (GWAS) meta-analysis of chronic back pain (CBP). Adults of European ancestry were included from 15 cohorts in the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium, and from th

Populations of Dactylorhiza incarnata (early marsh orchids) with spotted leaves appear in widely separate parts of Europe including Scandinavia and the Baltic area, The Alps, and Britain and Ireland. Forms with spotted leaves have often been segregated as a separate subspecies, D. incarnata subsp. cruenta. Although previous studies have indicated that the taxon is heterogeneous, it is not known hoPopulations of Dactylorhiza incarnata (early marsh orchids) with spotted leaves appear in widely separate parts of Europe including Scandinavia and the Baltic area, the Alps, and Britain and Ireland.
