Employing a large number of antennas at the base station, massive MIMO significantly improves spectral efficiency and transmit power efficiency. On the other hand, massive MIMO also introduces unprecedented implementation challenges, especially in terms of processing and storage of large-size channel state information (CSI) matrices. Since on-chip memory is generally very expensive and has limited
Light-by-light scattering (γγ → γγ) is a quantum-mechanical process that is forbidden in the classical theory of electrodynamics. This reaction is accessible at the Large Hadron Collider thanks to the large electromagnetic field strengths generated by ultra-relativistic colliding lead ions. Using 480 μ1 of lead-lead collision data recorded at a centre-of-mass energy per nucleon pair of 5.02 TeV by

Popular Abstract in SwedishVad är barnets bästa i en domstolsprocess? Hur skall barns behov och intressen tillvaratas under utredningsarbete och beslut, och av vem? I vilken utsträckning skall barn få komma till tals, och varför? Under senare år har barns rättsliga ställning inom olika områden tilldragit allt större intresse inom rättsvetenskapen, bland rättstillämpare och hos allmänheten. SverigeThis dissertation deals with the question of the child´s legal status in legal proceedings concerning its own person. Special problems that may arise in investigations concerning the situation of the child and in decisions on measures to be taken in the best interest of the child are also examined. The Care of Young Persons Act (1990:52) constitutes the framework of this study. According to the Ac
alpha(1)-Microglobulin is a 26-kd protein, widespread in plasma and tissues and well-conserved among vertebrates. alpha(1)-Microglobulin belongs to the lipocalins, a protein superfamily with highly conserved 3-dimensional structures, forming an internal ligand binding pocket. The protein, isolated from urine, has a heterogeneous yellow-brown chromophore bound covalently to amino acid side groups a
We consider two interrelated tasks in a synchronous n-node ring: distributed constant colouring and local communication. We investigate the impact of the amount of knowledge available to nodes on the time of completing these tasks. Every node knows the labels of nodes up to a distance r from it, called the knowledge radius. In distributed constant colouring every node has to assign itself one out
INTRODUCTION: Non-native linguistic tone learning ability has been found to be influenced by the anatomy of primary auditory regions in the left hemisphere (Wong et al., 2008). In native speakers, however, where phonemic categories are firmly established, variations in the macrostructure of more secondary auditory processing areas might be expected to affect performance. The present study investig
To compete on the global market many companies need to undergo fundamental organizational changes. However, many companies fail to make successful transformations. To identify the factors that contribute to a successful transformation, some researchers have focused on a micro perspective and investigated employees’ characteristics and attitudes (e.g., organizational commitment, readiness for chang
When an internet user opens a web page containing an advertising slot, how is it determined which ad is shown? Today, the most common software-based approach to trading advertising slots is real time bidding: as soon as the user begins to load the web page, an auction for the slot is held in real time, and the highest bidder gets to display their advertisement of choice. Auction bidding is perform
Robots have become important for the development of today’s society. They are known to obtain good accuracy and repeatability of tasks that either complement or replace human labour. Furthermore, as machine-learning is emerging in many technologies, it is important to consider the uncertainties that are introduced when this method is used in robotics. This work aims at developing and evaluating a

Detta project utfördes i samarbete med svenska förpackningsföretaget Tetra Pak Packaging Solutions AB. Deras huvuduppgift är att utveckla förpacknngsmaterial, processer och maskinlinjer som krävs för att producera laminatet, vilket är att flerskiktsmaterial som vanligtvis består av papper, plast och aluminium för att skapa en stark och skyddande barriär för flytande livsmedel. För att skapa laminaThis project was carried out in cooperation with Swedish packaging company Tetra Pak Packaging Solutions AB. Their main purpose is to develop the packaging material, process, and machine lines needed to produce the laminate, which is a multi-layered material typically made by combining paper, plastic, and aluminum to create a strong, protective barrier for liquid food packaging. In order to create
Aim: To establish outcomes of a priority setting partnership between participants with diabetes mellitus and clinicians to identify the top 10 research priorities for preventing and treating diabetic foot ulcers (DFUs). Methods: Due to the COVID-19 pandemic, the James Lind Alliance Priority Setting Partnership process was adapted into a digital format which involved a pilot survey to identify unde
Dietary phosphorus restrictions are usually recommended for people on haemodialysis, although its impact on patient-relevant outcomes is uncertain. We aimed to evaluate the association between total phosphorus intake and its sources with mortality in haemodialysis. Phosphorus intake was ascertained within the DIET-HD study in 8110 adults on haemodialysis. Adjusted Cox regression analyses were cond
Den fotokemiska reaktorn vid Copenhagen Centre for Atmospheric Research, Köpenhamns universitet, har i denna studie används för att bestämma nya värden på hastighetskonstanterna k(i) för reaktionen: CH3Br + OH -> produkter (i) och k(ii) för reaktionen: CH3Br + O(1D) -> produkter. (ii) Radikalerna (O(1D) och OH) framställdes i studien genom att fotolysera ozonmolekyler med UV-C-ljus. OxidationsprocThe photochemical reactor in Copenhagen Centre for Atmospheric Research, University of Copenhagen, was used to determine new values for the rate constants k(i) and of the reaction: CH3Br + OH −> products (i) and k(ii) for the reaction: CH3Br + O(1D) −> products. (ii) The radicals (O(1D) and OH) were produced by photolysis of ozone molecules with UV-C light. The oxidation process was monitored by a
“The important criterion for a graph is not simply how fast we can see a result; rather it is whether through the use of the graph we can see something that would have been harder to see otherwise or that could not have been seen at all.” William S. Cleveland When presenting graphs for people with visual impairments the solutions found on the market today often present pure data values only. Over
Med elasticitetsteori kan man inte beskriva hur en statiskt obestämd konstruktion där materialet kan plasticeras går till brott. Enligt elasticitetsteori och ett antagande om ett sprött brott vid en viss spänning går en konstruktion till brott så fort denna spänning uppnås i det högst belastade snittet. Det som egentligen sker är att materialet plasticeras vilket leder till en momentomlagring. KonUsing theory of elasticity it is not possible to describe exactly how a statically indeterminate structure collapses. Theory of elasticity is often combined with an assumption of breakage at a certain level of stress, this meaning that a structure will break as soon as this level of stress is reached in the most heavily loaded section. A plastic hinge will occur followed by a changed distribution
A cochlear implant (CI) is a device that provides individuals with severe to profound hearing impairment (SPHI) with auditory stimulation, which makes it possible for them to develop skills related to spoken communication. We have little knowledge about how hearing with a CI influences cognitive and communicative development and there is a need for development of methods for assessment. The genera
Background: Recently, some US cohorts have shown a moderate association between red and processed meat consumption and mortality supporting the results of previous studies among vegetarians. The aim of this study was to examine the association of red meat, processed meat, and poultry consumption with the risk of early death in the European Prospective Investigation into Cancer and Nutrition (EPIC)
The Swedish referendum on the euro in September 2003 is an exceptional event for researchers of monetary unions and of European economic integration. Voters chose between maintaining the domestic currency, the krona, and replacing it with the euro, the single currency of the European Union. The referendum revealed significant dividing lines between Yes- and No-voters in areas such as income, edu
