Importance: Disrupted sleep commonly occurs with progressing neurodegenerative disease. Large, well-characterized neuroimaging studies of cognitively unimpaired adults are warranted to clarify the magnitude and onset of the association between sleep and emerging β-amyloid (Aβ) pathology. Objective: To evaluate the associations between daytime and nighttime sleep duration with regional Aβ pathology

Since the beginning of African decolonisation in the mid-twentieth century, many newly independent countries struggled to embark upon a path of sustained economic growth to raise their populations out of poverty. One of these countries is Tanzania. Surrounded by the Great Lakes on the west and bordering the Indian Ocean to the east, Tanzania is the fifth-most populous country in Africa. It is also

Having been unavailable for many years, the Swedish film Rätten att älska (‘The right to love’) was restored by the Swedish Film Institute in 2013 and made accessible for research. In many ways a typical example of the sex education film genre of its time, the film is simultaneously unusual because it deals with children’s sexuality. This article explores and discusses the representation of childr

The Face of AIDS film archive at Karolinska Institutet, Sweden, consists of more than 700 hours of unedited and edited footage, shot over a period of more than thirty years and all over the world by filmmaker and journalist Staffan Hildebrand. The material documents the HIV/AIDS pandemic and includes scenes from conferences and rallies, and interviews with activists, physicians, people with the in

Swedish filmmaker Jan Halldoff's fiction film Korridoren (The Corridor) premiered in 1968 to a mainly positive Swedish reception. Shot at Karolinska Hospital and criticizing the Swedish healthcare system, the film became much debated and can furthermore be seen as a turning point in Swedish film history regarding the portrayal of medical institutions and professionals. In this article, the film an

Spatially coupled serially concatenated codes (SC-SCCs) are constructed by coupling several classical turbo-like component codes. The resulting spatially coupled codes provide a close-to-capacity performance and low error floor,which have attracted a lot of interest in the past few years. The aim of this paper is to perform a comprehensive design space exploration to reveal different aspects of SC

In recent years the number of connected devices and the demand for high data-rates have been significantly increased. This enormous growth is more pronounced by the introduction of the Internet of things (IoT) in which several devices are interconnected to exchange data for various applications like smart homes and smart cities. Moreover, new applications such as eHealth, autonomous vehicles, and c

This paper presents a reasoned account of the critiques addressed to the circular economy and circular business models. These critiques claim that the circular economy has diffused limits, unclear theoretical grounds, and that its implementation faces structural obstacles. Circular economy is based on an ideological agenda dominated by technical and economic accounts, which brings uncertain contri

Elle s’est également imposée comme principe de développement stratégique d’entreprises, villes, régions, et réseaux professionnels. On connait moins bien les critiques théoriques et pratiques dont l’économie

With the technological advancements in electronics, thermal management is becoming a concern that considerably affects the performance of electronic parts and systems, and two-phase immersion cooling is attracting attention due to its preferable cooling capacity. In immersion cooling, heat is dissipated by boiling that occurs on hot surfaces immersed in coolants. Therefore, it is essential to inve
