Spatial multiplexing using Massive MIMO has been shown to have very promising properties, including large gains in spectral efficiency and several orders of magnitude lower transmit power, as compared to today's access schemes. The properties of massive MIMO have been studied mostly for theoretical channels with independent and identically distributed (i.i.d.) complex Gaussian coefficients. To eff
The question whether very weak, low frequency magnetic fields can affect biological matter is still under debate. The theoretical possibility of such an interaction is often questioned and the site of interaction in the cell is unknown. In the present study, the influence of extremely weak 60?Hz magnetic fields on the transport of Ca2+ was studied in a biological system consisting of highly purifi
Abstract—This article have been written in cooperation with The Swedish Defense Research Agency (FOI). The article proposes a method to calibrate hydrophone positions for improved underwater survailence in The Baltic Sea. The idea with the method is to use the sound of a powerboat and a novel beamforming algorithm for array element localisation (AEL). There are strategic military advatages to this
Vår undersökning kommer handla om kundfokuset inom agila utvecklingsmetoder. Vi vill skapa en förståelse samt en bredare bild över hur arbete och kommunikationen inom agila utvecklingsmetoder påverkar företag och deras kunder. Denna frågeställning har även en stor koppling till det systemvetenskapliga programmet som vi tre författare läser tills Juni, 2015. Vi har i rapporten använt oss utav litte
The paper examines the impact of the mining sector's closure on population decline patterns in the Principality of Asturias, Spain. It utilizes two distinct databases of own construction that provide disaggregated data on the region's 78 councils. The first database encompasses demographic information spanning from 1900 to the present day, while the second database contains socioeconomic d
This paper analyzes the existence of market power on the Nordic electricity market between 2018-2022, and if the energy market turbulence caused by covid-19, and later deepened following the war in Ukraine affected producers' bidding behavior. Market power was tested using Cournot assumptions to see if producers withheld output strategically when demand was more inelastic. Auction data on syst

The statistical sparse jump model, a recently developed, robust and interpretable regime-switching model, is used to analyze the factors driving the return dynamics of the largest cryptocurrencies. This method simultaneously incorporates feature selection, parameter estimation, and state classification. A wide range of candidate features is considered, including cryptocurrency, sentiment, and fina
Concepts are an important element of the way international lawyers think and talk about international law. They materialise as conceptual terms, such as ‘jurisdiction’, ‘self-defence’ and ‘abuse of rights’. To enable a critical evaluation of international law and legal discourse, it is important that single instances of use of such terms be fully understood. This task presupposes a full recognitio
The critique of the legal form of capitalism by E. B. Pashukanis has risen to prominence once again. However, the negative origin of the concept of the legal form, the critique of formalism and instrumentalism, has received too little attention. This essay substantiates the significance of Pashukanis’s critique, avoiding both overly general and narrow conceptions. Moreover, it proposes that his neThe critique of the legal form of capitalism by E. B. Pashukanis has risen to prominence once again.
