Non-Orthogonal Multiple Access (NOMA) is studied under statistical Channel State Information (CSI) and probabilistic constraints. Unlike the conventional power domain only NOMA, the definition of NOMA here considers both the power and the frequency domains simultaneously, where a flat power spectrum is assumed for each UE. This increases the capacity region when compared to the conventional definiti
For a pair of closely located and cooperating user equipments (UEs), a precoder is designed at the base station (BS) which considers the UE cooperation. The UEs collaborate over an out-of-band side-link with a finite capacity. The side-link may be used for interference cancellation (IC) or for relaying decoded symbols. The precoder has two parts, a cooperative part based on channel inversion and a
STUDY DESIGN: This prospective, randomized study compares the efficacy of surgical and conservative treatments in patients with long-lasting cervical radicular pain.OBJECTIVES: To compare the effects of surgery, physiotherapy, and a cervical collar.SUMMARY OF BACKGROUND DATA: There are no previous controlled outcome studies that have compared surgical treatment with nonsurgical treatment of patien
Background: Echolucent carotid plaques have been related to an increased risk of ischemic cerebrovascular events. The aim of the present study was to evaluate whether a new objective ultrasonographic parameter, the statistical geometric feature (SGF), reflecting spottiness of carotid plaques, can be associated with cerebrovascular symptoms and with a rupture-prone plaque phenotype. Methods: The pl
This prospective, randomised study compares the efficacy of surgery and conservative treatments in patients with cervical radiculopathy. The study group comprised 81 patients with long-lasting cervicaloradiculopathy, with a pain distribution corresponding to a significant nerve root compression, verified by magnetic resonance imaging or computed tomographic myelography. The patients were randomly
Heldagsseminariet handlar om lantmäteriförrättningar, där vi särskilt riktar in oss på lantmäteriförrättningarnas betydelse för fastighetsbranschen. Vi strävar alltid efter att ordna seminarier som ger klara och handfasta besked om centrala fastighetsrättsliga ämnen. Denna nionde gång är ämnet lantmäteriförrättningar. Ett centralt och ämne inom den speciella fastighetsrätten som vi nu tar ett saml
Objectives: To determine the intra- and inter-observer agreement of erosions detected and scored with cone-beam computed tomography (CBCT) of bones in the hands and feet, and to compare CBCT with conventional radiography (CR) for assessment of bone erosions in patients with long-standing rheumatoid arthritis (RA). Method: Thirty patients with long-standing RA from the Better Anti-Rheumatic Pharmac
Summary: We aimed to study the risk of hip fracture and risk of hip arthroplasty among farmers in Sweden. Our results indicate that farming, representing an occupation with high physical activity, in men is associated with a lower risk of hip fracture but an increased risk of hip arthroplasty. Introduction: The risks of hip fracture and hip arthroplasty are influenced by factors including socioeco
The study of extrasolar planets and of the Solar System provides complementary pieces of the mosaic represented by the process of planetary formation. Exoplanets are essential to fully grasp the huge diversity of outcomes that planetary formation and the subsequent evolution of the planetary systems can produce. The orbital and basic physical data we currently possess for the bulk of the exoplanet
