Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e., the Kronecker model and the Weichselberger model, and a cluster-based m

S:t Jacobs church and burial site from medieval Lund was excavated in 1983. There has until now not been any osteological study and there is nearly no information about the church. To gain more information about the church and the burials, an osteological study has now been made. The analysis is based on aging and sexing the skeletons to enable a socio-economic discussion. 93 out of 320 excavated

Abstract Metal oxide semiconductor (MOS) capacitor was fabricated on the InGaAs substrate with Al2O3/HfO2 gate oxide. InGaAs is one of the promising candidates for advanced applications which require the lower power supply and high frequency. The high-k films (Al2O3/HfO2) were formed by atomic layer deposition (ALD) as an alternative to silicon dioxide (SiO2) to proceed the scaling of oxide to low

Prior to the accomplishment of this research, the compatibility of the classic e-servicescape conceptual model in the context Taobao and TMall in China were rarely found among existing e-servicescape literatures due to the standardization taken by both online platforms towards the establishment of individual webshops. Meanwhile, the conceptualization of social factors as social dimension of e-serv

Background. The definition of a "difficult" cannulation varies considerably in reports of endoscopic retrograde cholangiopancreatography (ERCP). Aims. To define a difficult cannulation, which translates into higher risk of post-ERCP pancreatitis. Patients and methods. Prospective consecutive recording of 907 cannulations in Scandinavian centers done by experienced endoscopists. Inclusion: indicati

Background: Trust as a measure of social capital has been documented to be associated with health. Mediating factors for this association are not well investigated. Harmful alcohol consumption is believed to be one of the mediating factors. We hypothesized that low social capital defined as low institutional trust is associated with harmful alcohol consumption. Methods: Data from the 2006 Swedish

Massive MIMO, also known as very-large MIMO or large-scale antenna systems, is a new technique that potentially can offer large network capacities in multi-user scenarios. With a massive MIMO system, we consider the case where a base station equipped with a large number of antenna elements simultaneously serves multiple single-antenna users in the same time-frequency resource. So far, investigatio

Background: We evaluated the efficacy and safety of the aromatase inhibitor exemestane in patients with advanced, persistent or recurrent endometrial carcinoma. Methods: We performed an open-label one-arm, two-stage, phase II study of 25 mg of oral exemestane in 51 patients with advanced (FIGO stage III-IV) or relapsed endometrioid endometrial cancer. Patients were stratified into subsets of estro

The purpose of this phase II randomized trial was to evaluate the effect and safety of interferon-2a (IFN) in combination with extended dosing rituximab in patients with symptomatic, advanced indolent lymphoma responding to a standard single course of rituximab. Totally 123 patients were treated with rituximab 375mg/m2 once weekly for 4 weeks leading to 14 complete response (CR; 11%), 56 partial r

Background: The use of inhaled corticosteroids (ICSs) is associated with an increased risk of pneumonia in patients with COPD. However the risks of other respiratory infections such as TB and influenza remain unclear. Methods: Through a comprehensive literature search of MEDLINE EMBASE CINAHL Cochrane Library and ClinicalTrials.gov from inception to July 2013 we identified randomized controlled tr

Objectives. Studies have suggested a correlation between untreated celiac disease and risk for other autoimmune diseases. We investigated the prevalence of thyroid autoimmunity in 12-year-old children (i) with symptomatic celiac disease diagnosed and treated with a gluten-free diet, (ii) with screening-detected untreated celiac disease, and (iii) without celiac disease. Methods. Blood samples from

Objectives. Cirrhosis is a well-known risk factor for hepatocellular cancer, but the true risk in autoimmune hepatitis (AIH) is scarcely studied. Other cancers may arise after prolonged use of immune-modulating drugs. The aim of this study was to investigate the cancer risk in a large cohort of AIH patients. Material and methods. Six hundred and thirty-four Swedish patients in a well-defined cohor

Objectives. To study the correlation between Sunnybrook and House-Brackmann facial grading systems at different time points during the course of peripheral facial palsy. Study Design. Prospective multicenter trial. Setting. Seventeen otorhinolaryngological centers. Subjects and Methods. Data are part of the Scandinavian Bell's palsy study. The facial function of 1920 patients with peripheral facia

Beta-microseminoprotein (MSP) is one of the most abundant proteins secreted by the prostate gland. Because MSP is also synthesized in nonreproductive organs, the establishment of a solid relationship between the levels of MSP in serum and semen is crucial for future studies connecting MSP with aging or diseases of the prostate gland. We developed a specific, competitive, europium-based immunoassay
