Massive MIMO is a promising technology to connect very large numbers of energy constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge resides in partitioning the many nodes in groups that can communicate simultaneously such that the mutual interference is minimized. We here propose node partitioning strategies that do not require full channel state in

For a long time, laboratory work has been an important part of science teaching. Curricular objectives of laboratory work have remained mostly unchanged for over a century but have changed somewhat over the past sixty years as a result of political decisions and educational trends. Technology development is reflected in the increased use of digital equipment, which has also led to continuously cha

In patients with asthma and chronic obstructive pulmonary disease, the addition of long-acting β2-agonists (LABA) to glucocorticosteroids (GCS) results in better control than increasing the dose of GCS alone. In smooth muscle cells and fibroblasts, one apparent underlying mechanism involves the ability of LABAs to activate the glucocorticoid receptor (GR). The present study investigates the effect

Multiple sclerosis is a neuroinflammatory degenerative disease, caused by activated immune cells infiltrating the CNS. The disease etiology involves both genetic and environmental factors. The mouse genetic locus, Eae27, linked to disease development in the experimental autoimmune encephalomyelitis (EAE) model for multiple sclerosis, was studied in order to identify contributing disease susceptibi

Context: Older people with multimorbidity are vulnerable and often suffer from conditions that produce a multiplicity of symptoms and a reduced health-related quality of life. Objectives: The aim of this study is to explore the experience of living with a high symptom burden from the perspective of older community-dwelling people with multi-morbidity. Method: A qualitative descriptive design with

In Sweden, as in other industrialised nations, occupational exposure limits are considered to be an important tool for chemical risk management, although many other factors also play a role in occupational safety and health management. The aim of this study was to investigate the role of occupational exposure limits in relation to information about, and the risk perception of, chemicals. An interv

Physiological processes of terrestrial plants regulate the land-atmosphere exchange of carbon, water, and energy, yet few studies have explored the acclimation responses of mature boreal conifer trees to climate change. Here we explored the acclimation responses of photosynthesis, respiration, and stomatal conductance to elevated temperature and/or CO2 concentration ([CO2]) in a 3-year field exper

This paper deals with policy options for constructing cross-border innovation systems. Trans-frontier cooperation and policies to stimulate increased interaction between neighbouring regions that belong to different nation states are not new phenomena. There is a large body of work on the governance structures of such areas and the array of public policies geared towards promoting increased econom

Abstract This paper offers a new description and explanation of morphological agreement, argument-verb agreement in particular. The hypothesis explored is that argument-verb agreement is directly related to selection of arguments (s-selection), i.e. s-selectional features are in fact ф-features ([PERSON, NUMBER(, GENDER)], and that morphological argument-verb agreement mirrors this relation. Call

In language acquisition it is important to imitate the native speakers of the language. For the young child it is natural to imitate both the language and the behaviour of the culture. Imitation, or adaptation (Markham 1997), is also useful in second language acquisition to learn how to pronounce the words and to learn the prosody of the language. For most people it is difficult to learn to speak

Risk and vulnerability analyses are a required decision support tool in processes to improve societal safety and crisis preparedness at national, regional and local levels in several European states. Analyses result in risk images, which are the stakeholders’ views of events that must be addressed in planning processes related to topics such as land use and crisis management. Hence, risk and vulne

The new public diplomacy is a major paradigm shift in international political communication. Globalisation and a new media landscape challenge traditional foreign ministry ‘gatekeeper’ structures, and foreign ministries can no longer lay claim to being sole or dominant actors in communicating foreign policy. This demands new ways of communicating foreign policy to a range of nongovernmental intern

Glycero-3-phosphocholine (GPC), the product of the complete deacylation of phosphatidylcholine (PC), was long thought to not be a substrate for reacylation. However, it was recently shown that cell-free extracts from yeast and plants could acylate GPC with acyl groups from acyl-CoA. By screening enzyme activities of extracts derived from a yeast knock-out collection, we were able to identify and c

This study investigates how the debt levels of firms belonging to the Nordic market change over time and what determines these changes. We find that contemporaneous changes in leverage are mainly determined by profitability, market timing, leverage deficits (deviations from target leverage) and changes in targets. We find two factors whose effects persist for at least ten years, namely profitabili

Purpose: We intend to study what exactly happens to organizational identity construction during a crisis. Thereby we are particularly interested in elucidating the influencing factors and levels for identity construction. We investigate how organizational identity was deconstructed and want to suggest a discussion of the terminology as the notion of “identity construction” does not seem to be appr

The aim of this paper is to examine how various types of investors react, and how ownership structures of firms involved in unethical tax practices change once these unethical behaviours are made public. It combines news data with market data to identify investor reactions to tax scandals. Using a staggered diff-in-diff approach, we find that different ownership classes such as hedge funds, banks,

Denna studie undersöker hur irritation och frustration uppstår, uttrycks och hanteras i vardagliga interaktioner med röstassistenter i hemmet. Tidigare forskning har ofta behandlat irritation som ett tillfälligt svar på tekniska misslyckanden eller som en indikation på bristande användbarhet. I denna uppsats ser vi istället på irritation som en aktiv och återkommande process som bidrar till den påThis study examines how irritation and frustration emerge, are expressed, and are managed in everyday interactions with voice assistants in the home. Previous research has often treated irritation as a temporary response to technical failures or as an indicator of poor usability. In this thesis, irritation is instead understood as an active and recurring process that contributes to the ongoing dom

Against the backdrop of escalating US-China competition, the Association of Southeast Asian Nations (ASEAN) is situated in a key geopolitical position. This is not the first time ASEAN has faced great power competition within the region. During the Cold War, to respond to the US-Soviet rivalry, ASEAN developed neutrality as one of its fundamental norms. This thesis aims to explore the role and evo

Can the way a word is used give legitimacy to a political movement? Feminism, Violence, and Representation in Modern Italy traces the use of the word "femminicidio" (or "femicide") as a tool to mobilize Italian feminists, particularly the Union of Women in Italy (UDI). Based on nearly two years of fieldwork among feminist activists, Giovanna Parmigiani takes a broad look at the many ways in which
