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
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
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
Memory integration is how series of similar memories can merge into overlapping representations as one abstract model of behavior to anticipate present and future episodes – facilitating instrumental use of episodic experience for higher-order inferences. Previous research has showed that a novel memory of reward can travel backwards in time through episodic memory and generalize its contents to p
This project was done for the company Beijer Electronics Products AB and the task was given by the hardware development department of the company. The project was about developing a concept proposal for a new generation operator panels. This was done to inspire the product developers at Beijer Electronics with innovative ideas before the actual operator panel development. More in detail the object
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
As the industrial, commercial, and domestic prevalence of Internet of Things networks grows, so does the search for viable solutions to decrease their energy consumption. One common solution is using a low-power proxy that can control the power state of the devices within the network. To evaluate such solutions, either implementations can be made and measured for energy consumption, or energy mode
The study aimed at (a) investigated the ability of potential lactic acid bacteria (LAB) to ferment quinoa milk, and (b) formulating a method for producing fermented quinoa milk. To meet the objectives, Lactobacillus pentosus and Pediococcus pentosaceus two native bacterial strains were tested. Quinoa milk elaboration was optimized at laboratory scale by selecting an appropriate quinoa/water propor
To compete on the global market many companies need to undergo fundamental organizational changes. However, many companies fail to make successful transformations. To identify the factors that contribute to a successful transformation, some researchers have focused on a micro perspective and investigated employees’ characteristics and attitudes (e.g., organizational commitment, readiness for chang
Reaching the targets of the Paris Agreement requires acceleration of low-carbon energy transitions. At the same time, it is not fully understood why some technologies spread more rapidly and widely than others. This thesis advances our understanding of the diffusion of large-scale low-carbon technologies by bridging technology diffusion studies and political economy of transitions. Through combini
Protection of humanitarian aid workers (HAWs) is a challenging task. There are various reports on the topic where much research seems to focus on traditional physical attacks and intentional violence against HAWs (security) rather than the accidental event risks (safety) or discussing it separately. These risks are usually defined by the organization’s security risk management holding the power in
