A Light Signalling Approach to Node Grouping for Massive MIMO IoT Networks

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

A descriptive study of pain treatment and its follow-up in primary care of elderly patients after orthopaedic care

Background: Pain treatment post orthopaedic care in the elderly is complicated and requires careful follow-up. Current guidelines state all patients prescribed opioids should have a plan for gradual reduction, with the treatment progressively reduced and ended if any pain remains after more than three months. How this works in primary care remains to be explored.The aim was to describe pain treatm

The role of the understory in litter DOC and nutrient leaching in boreal forests

Dissolved organic carbon (DOC) derived from plant litter plays an important role in the ecosystem carbon balance and soil biogeochemistry. However, in boreal coniferous forests no integrated understanding exists of how understory vegetation contributes to litter leaching of DOC, nitrogen (N) and phosphorus (P) with different bioavailability at the forest stand level. We characterized water extract

Applicability of ultrasonic tomographic technique for progressive damage evaluation in prismatic rock specimen

Several damage processes are associated with the loading of intact rock specimens including closure of existing microcracks, initiation of cracks, and finally development of cracks. Ultrasonic imaging techniques have proven to be very successful in providing relatively high-resolution images of the damage processes in the rock. Ultrasonic velocity tomography is a full-field measurement technique t

Remarkable preservation of microfossils and biofilms in mesoproterozoic silicified bitumen concretions from Northern China

Prokaryotes, often generally referred to as “bacteria,” are the original and thus oldest life on Earth. They have shaped the chemical environment of the Earth, but they are difficult to find as ancient fossils due to their subtle structure. Here we report well-preserved fossilized microbial communities in silicified bitumen concretions from unit 3 of the Xiamaling Formation (1.39 Ga) in northern C

Oxygen, climate and the chemical evolution of a 1400 million year old tropical marine setting

The Xiamaling Formation is an exceptionally well-preserved sedimentary succession deposited on a marine passive margin about 1400 million years ago. We used a multi-proxy approach, including iron speciation, trace metal dynamics, and organic geochemistry, to explore the evolution of ocean chemistry through most of the Xiamaling Formation. This evolution is put in the context of the paleogeography

Convergent Evolution, Evolving Evolvability, and the Origins of Lethal Cancer

Advances in curative treatment to remove the primary tumor have increased survival of localized cancers for most solid tumor types, yet cancers that have spread are typically incurable and account for >90% of cancer-related deaths. Metastatic disease remains incurable because, somehow, tumors evolve resistance to all known compounds, including therapies. In all of these incurable patients, de novo

Brief Report : Interferon-γ-Inducible Protein 10-A Potential Marker for Targeted Viral Load Monitoring of Antiretroviral Treatment?

BACKGROUND: The use of surrogate markers for targeting viral load (VL) testing could be an alternative to universal VL testing during antiretroviral treatment (ART) and would allow for more effective resource allocation. We investigated the correlation between levels of HIV RNA and interferon-γ-inducible protein 10 (IP-10) in Ethiopian adults at 12 months after ART initiation. In addition, we spec

Rawlsian Constructivism : A Practical Guide to Reflective Equilibrium

Many normative theorists want to contribute to making the world a better place. In recent years, it has been suggested that to realise this ambition one must start with an adequate description of real-life practices. To determine what should be done, however, one must also fundamentally criticise existing moral beliefs. The method of reflective equilibrium offers a way of doing both. Yet, its prac

Är Gud påhittad eller verklig?

Populärvetenskaplig framställning av den religionsfilosofiska frågan om realism/anti-realism applicerat på den centrala religiösa termen "Gud". Lösningsförslag utifrån pragmatisk realism och referensteorier presenteras.

Moderaternas ideologiska grundsyn : En uppföljning av debatten under det sena 1900-talet

Aims Three doctoral theses by Aronson (1990), Hylén (1991) and Ljunggren (1992) drew different conclusions regarding the ideological development of the Swedish Conservative (Moderate) party during the 20th century until the 1980s. This study investigates the party programs from 1904 to 2011/2013 with regard to the party’s most fundamental perception of reality in terms of a collectivistic versus i

Decentraliserad diakoni - en studie av tre församlingar

Denna rapport handlar om Svenska kyrkans sociala arbete, dess diakoni, i tre församlingar i mitten av 2010-talet. Svenska kyrkan har allt sedan den skildes från staten år 2000 på olika sätt behövt anpassa sig till att den numera är en frivilligorganisation bland andra, låt vara med en tydlig särställning i kraft av sin historia, storlek och tillgång till resurser. Vi är intresserade av att undersö
